    Study on the requirement of organic primer for titanium dioxide in the plastics industry

    As a white pigment filler of high quality, has many applications, including in plastic profiles, colormasterbatch, paints, emulsions paints, powders paints for paper making, cosmetics and chemical fibers. It can be used with both the solvent and water systems. The different application and application systems have additional requirements in selecting organic coatings agents. Traditional TMP and peg are no longer sufficient to meet these requirements. They also have some negative effects, like the bubble problem. In order to achieve an acceptable treatment effect for the application, it is important to use different organic treating agents according to the different USES (applications) of titanium dioxide. In addition to the different USES for titanium dioxide, there are also differences in titanium dioxide application performance requirements.
    Plastics - Requirements on titanium dioxide
    1. High viscosity extrusion/dispersion lubricant
    As plastic products become stronger and cheaper, they add more color filler. However, as the resin proportion decreases and compatibility between components becomes more challenging, it can cause the surface to be rough and uneven in color. Consider the colormasterbatch that is commonly used in plastics: it's made by extrusion of titanium dioxide and granulation after being kneaded with high temperature organic resins such as polyethylene wax or high-pressure polyester. It is necessary to use the least amount of carrier resin to moisten the most titanium dioxide possible in order to achieve a high-concentration white masterbatch. This will avoid low resin compatibility when applied. In order to produce masterbatches, titanium dioxide must have excellent wettability on the surface and excellent lubrication. If not, it is difficult to granulate or disperse.

    2. Temperature/weather Resistance
    Before processing or forming, the vast majority of plastics products, regardless of their type, processing method or resin, must be in high-temperature melt with titanium dioxide and additives. Processing temperatures for plastics are around 200 degrees, or higher. The decomposition of some components at this temperature will cause pigment migration, porosity and a serious impact on the physical strength and surface quality of plastic products. Each component of the formula should have excellent temperature resistance. For plastics used outdoors or in a healthy light environment (such plastic films, electrical appliances, etc.) UV resistance should also be taken into consideration. In PVC products, a stabilizer containing lead is added. This type of stabiliser is easily reacted with other active chemical substances at high temperature and produces black substances. Lead stabilizers cannot react with organic coating agents on titanium dioxide surfaces.

    3. Dry Powder Fluidity/Moisture Resistant
    As more and factories adopt continuous production line for plastics, raw materials related to it (like resins, fillers or pigments) are also metering continuously using transmission belts. Imagine that the flow rate of titanium dioxide dry is low. The powder will then get stuck in the belt of the transmission or block the screen hole. This can lead to titanium dioxide not being accurately measured or added smoothly.

    Brief introduction of silicon carbide products

    Introduction to silicon carbide products
    Silicon carburide also known by the names moissanite, emery or coal coke, is an organic substance with a formula of SiC. It is produced by a high-temperature resistive furnace using raw materials, such as wood chips, quartz sand or coal coke. Salt is required for green silicon carbide. In nature, silicon carbide is found in the rare mineral moissanite. It is also called gold steel or refractory grit. In China, silicon carbide is made up of two types: green and black. They are both hexagonal crystals and have a specific gravity ranging from 3.20 to 3.25.

    Both black silicon carburide and green silica carbide belong to the aSiC. Black silicon carbide has a SiC content of 95% and is more durable than green silicon carbide. It is used primarily for materials that have low tensile strengths, like glass, ceramics or stone. Green silicon carbide has a SiC content of over 97% and is self-sharpening. It is used primarily for the processing of cemented carbide (a titanium alloy), optical glass and titanium alloy. Also, it can be used to fine grind high-speed steel and for honing and grinding cylinder liners. There is also a cubic silicon-carbide, which is a yellowish-green crystal, prepared through a special procedure. The abrasive tools used to make them are suitable for superfinishing bearings. Surface roughness is processed between Ra320.16microns and Ra0.040.02 microns.

    Aside from being an abrasive, silicon carbide can be used in many other ways. This is due to its chemical properties that are stable, such as high thermal conductivity. The powder of silicon carbide can be used to coat a specific impeller, cylinder or other part of a turbine. The inner wall of the refractory can be improved to increase its resistance to abrasion and its life span by upto 2 times. Low-grade Silicon carbide (containing approximately 85% SiC), which is a deoxidizer of excellent quality, can improve the steelmaking process and speed. It also allows for better control over chemical composition. Silicon carbide can also be used to produce silicon carbide for electric heater elements.
    It is the second hardest substance in the world, after diamonds (10). It is a good thermal conductor, a semiconductor that can resist oxidation even at high temperatures.

    There are at least 70 crystal forms of silicon carbide. Allomorphs of silicon carbide are the most common. It has a hexagonal crystalline structure and is formed above 2000 degC at high temperatures. Below 2000 degC b Silicon Carbide with cubic crystals, similar to diamonds, is formed. The network can be seen on the page. It is eye-catching due to its larger surface area unit than the a catalyst type, even though heterogeneous catalyst support is used. A type of silicon carbide called m-silicon carbide is more stable and makes a nicer sound when it collides. However, until now these two types had not been used commercially.
    Due to its high sublimation temp (approximately 27°C) and 3.2g/cm3 specific weight, silicon carbide makes a great raw material for high temperature furnaces or bearings. It does not melt at any pressure, and it has a very low chemical activity. Its high thermal conductivity and breakdown electric field strength as well as its high maximum current densities have led many to try to replace silicon when it comes to high-power semiconductor components. It has a high coupling effect to microwave radiation.
    The color of pure silicon carbide, however, is black or brown when produced industrially. This is due to iron impurities. The silica coating on the crystal surface gives it a rainbow-like appearance. To

    Pure silicon carbide is a transparent, colorless crystal. The impurities in industrial silicon carbide cause it to be a light yellow or green color, but its transparency can vary depending on the purity. The cubic bSiC is also known as cubic silicon carbide. The different stacking of silicon and carbon atoms creates a variety of a SiC variants. Over 70 types have been identified. bSiC is transformed into aSiC at temperatures above 2100degC. Industrial silicon carbide is produced by refining petroleum coke and high-quality sand in a resistance oven. The silicon carbide blocks that have been refined are crushed and then subjected to acid-base washing, magnetic separation, sieving, or water selection.
    It is artificial because silicon carbide has a low natural content. The standard method is to combine quartz sand, coke with silica or petroleum coke. Add salt and wood chips and heat to 2000degC in an electrical furnace.
    Its excellent hardness has made it an indispensable abrasive, but its range of applications goes beyond that of general abrasives. Due to its thermal conductivity and high temperature resistance, it is a popular choice for kiln furniture in tunnel kilns. The electrical conductivity of this material makes it a vital electric heating element. SiC smelt pellets (or SiC blocks) are needed to make SiC products. It is not natural garnet, also known as emery. In the industrial production of SiC, quartz, petroleum coal, etc. is usually used. As raw materials, as auxiliary recovery material, or as spent materials. After grinding or other processes, the materials are blended to a charge that has a reasonable particle size and ratio to adjust its gas permeability. An appropriate amount must be added. To prepare green silicon carbide at high temperatures, you need to add the correct amount of sodium chloride. Special silicon carbide electric heaters are used for the thermal equipment to prepare SiC smelting at high temperatures. It consists of a furnace bottom, an end wall with electrodes attached to the inner surface of its surface, a removable sidewall as well as the core body of the electric heater. Both ends of this furnace are electrode-connected. This electric heater uses what is known as buried-powder firing. As soon as you turn it on, the heating begins. The furnace core is at 2500degC (or even higher, between 2660-2700degC). SiC synthesizes at 1450degC (although SiC mainly forms above 1800degC), and co is released. SiC decomposes when the temperature is >=2600. The decomposed si, however, will form SiC and C in the charged.
    Each electric heater is equipped with transformers. Even so, during production only one electric heater is operated to adjust voltage according to electrical load characteristics in order to maintain constant electricity. The high-power furnace must be heated for around 24 hours. After an interruption of power, the reaction that generates SiC is complete. After a cooling time, the sidewalls can be removed. The charge is then gradually removed. Silicon carbide can be divided up into many different categories. These are also divided according to their use environment and more often than not, silicon carbide is used in machinery. Silicon carbide seal rings can, for example, be used to seal mechanical seals. These seal rings can be further divided into flat rings, moving bands, static rings and more. Our silicon carbide products can be made in different shapes according to the customer's requirements. For example, we can produce silicon carbide rings and plates.
    One of the silicon-carbide products is silicon carbide, a ceramic with high hardness. It also has high corrosion resistance and high temperature strength.
    Silicon carbide ceramics are ideal for seal rings. They have a high level of chemical resistance and wear resistance. The friction coefficient of silicon carbide ceramic is lower when combined with graphite than that of cemented carbide and alumina. Therefore, it can be used to produce PV values of high value, particularly in conditions where strong acids or alkalis are transported. The SIC-1 atmospheric sintered silicon carbide products manufactured by our company are characterized by high density and high hardness. Large production batches can be produced, as well as products of complex shapes. They are suitable to produce high-performance seals. They have exceptionally high PV values. And they're resistant to strong acids and Alkalis. Our company's SIC-3 silicon-carbide ceramic works are made from graphite. When combined with other materials, the friction coefficient of silicon carbide is low because it contains fine dispersed graphite particles. It is self-lubricating and therefore ideal for air-tight, dry-friction sealings. It is used to increase the seals' service life, and improve the reliability of the work.

    The furnace charge, after high-temperature calibration, is unreacted (to preserve heat in the furnace), and silicon carbide oxycarbide. (Semi-reactive Material. The main components of the material are C and siO. Binder layer (for bonding Very Tight Material Layer, main elements are C, SiO2, 40-60% SiC and Fe Al Ca Mg Carbonate), amorphous layer (the major component is 70-90 % SiC; it is Cubic SiC b-sic), second-grade SiC (the main ingredient is 90-95% SiC; the coating has formed hexagonal SiC (a coarse SiC crystal), first-class SiC (SiC content is less than 96%, and Unreacted material from the oxycarbide layers and a small part are collected for recycling. Large lumps, tight bonds and impurities such as charges are thrown away. The first-grade material is classified, then coarsely crushed or finely ground, treated chemically, dried, sieved, and magnetically separated into various size black and green SiC particles. It is necessary to go through the water selection process in order to produce silicon carbide.

    The difference between graphite and graphene

    Difference between graphite & graphene
    Graphene consists only of an atomic layer graphite, a layer composed of sp2-bonded atoms of carbon arranged in a honeycomb or hexagonal lattice. Graphite is a mineral that contains multiple layers of graphene. Graphene and graphite have slightly different structural compositions and production methods. This article will focus on the differences between these two materials.

    Graphite mineral
    Graphite is a naturally occurring carbon allotrope. It occurs naturally in metamorphic rock in many parts of the globe, including parts of South America. Asia and North America. The reduction of deposited carbon compound during metamorphism is responsible for the formation of this mineral.
    Graphene
    The chemical bonding in graphite is similar to that in diamond. The difference in hardness between these two compounds is due to the different lattice structures of the carbon atoms. Diamond contains three-dimensional bonds while graphite has two-dimensional bonds. Each layer of graphite contains weaker intermolecular bonding between the carbon atoms. This allows graphite to be a soft, ductile and flexible material because the layers slide against one another.
    Multiple studies have proven that graphite is a mineral of exceptional quality with unique properties. It has excellent heat and electrical conductivity, and it maintains its natural strength and stiffness even at temperatures higher than 3600degC. It is also chemically resistant and self-lubricating.
    Under standard conditions, graphite remains very stable despite its many forms. In various applications, graphite comes in different forms.
    Graphite's unique properties are superior to graphite. The thin plane of graphite makes it unsuitable for use as a structure material. Contrary to popular belief, graphene has the highest strength of any material. It's more than 400 times stronger than diamonds and over 300 times stronger that A36 structural steel.
    Due to graphite’s planar structure its electronic, thermal and acoustic properties are highly anisotropic. The phonons can pass more easily through an aeroplane than they do when traveling through one. The graphene material has an extremely high electron mobility. Like graphite, there are p(p), free electrons within each carbon atom.

    It is not surprising that graphene conducts electricity much better than graphite. This is due to electrons appearing as quasi-particles. They behave as though they were massless and can travel for long distances with no scattering. To achieve this high level of conductivity, it is necessary to dope the graphene to get past the zero density state visible at the Dirac's point.
    Graphene Production or Separation
    Scientists employ many different techniques to produce graphene. Mechanical peeling is also known as the tape technology and it's one of the most effective ways to make single-layer, or even few-layer, graphene. Many research institutes are working to develop the most efficient way to produce high-quality graphene at a large scale.

    The most appropriate technology for producing graphene is Chemical Vapour Deposition (CVD). The reduction process can be used to extract carbon from carbon-rich resources. This technology has a few disadvantages. It is hard to find a suitable substrate for growing the graphene and difficult to remove it from the substrate.

    In conclusion,
    Other methods of growing graphene are thermal engineering and carbon dioxide reduction. Due to the lower cost of production, this technique has attracted a lot attention. However, the current quality of the produced graphene does not match the material's theoretical potential. More time is required to finish the project.

    Magnesium nitride and its application

    What is Magnesium Nitride? Magnesium-nitride The inorganic compound Mg3N2 is composed of magnesium and nitrogen. It has a molecular weight of 104.9494. It is a cubic crystal. At room temperature, pure magnesium nitride powder is yellow-green. However, magnesium nitride that contains some magnesium oxide is off-white. Ammonia is formed when magnesium nitride reacts to water, as it does with many metal nitrides. Magnesium strips can be burnt with nitrogen to produce magnesium nitride. It is often used as a catalyst.
    Magnesium nitride chemical and physical properties
    Magnesium (Mg3N2) nitride is an inorganic compound with a cubic crystalline system made of nitrogen and magnesium. At room temperature, pure magnesium nitride powder is yellow-green. However magnesium nitride that contains some magnesium oxide impurities appears off-white. It is soluble in acid and slightly soluble with ethanol, but not ether.
    Magnesium Nitride, like other metal nitrides that react with water, forms ammonia. Reacts with non-metal oxides or acids to produce ammonium salts.

    Magnesium nitride preparation
    To prepare magnesium nitride The strip of magnesium can be burnt with nitrogen. The reaction is:
    It is possible to produce magnesium oxide in the above reaction if the Nitrogen is not pure. The reaction is better in dry NH3 gases.
    Install the magnesium chips in a sintered boat, or a porcelain vessel. Install the boat in a tube made of porcelain. One end is connected to the T-shaped tubing. The end of the porcelain pipe is connected with a U shaped tube. The tube is then filled with desiccant. The absorption device is made up of two conical flasks that are filled with dilute acid. Avoid inserting the tube of first absorption bottle beneath the surface of dilute sulfuric.
    Pour dry NH3 or N2 into porcelain tube. When the second bottle of absorption stops bubbling it means that air is out of the tube. The temperature will be increased to 800-850degC. The magnesium powder will then be heated for four-hours. As the magnesium powder heats up, the reaction begins. H2 must also be produced. The pressure of the NH3 during the reaction should be higher than that outside atmospheric pressure, to avoid back-suction. After the reaction has finished, shut off NH3, but keep the temperature at the same level. Continue to pass N2 over 1.5h in order to remove the adsorbed NH3*Mg3N2 on Mg3N2. The NH3*Mg3N2 molecule is highly liquescent, and should be stored in an airtight container.
    When the magnesium belt is burnt in the atmosphere, magnesium nitride, as well as magnesium oxide, will be produced.
    Magnesium Nitride Application
    1. Use as a catalyst in the preparation nitrides other elements that have high hardness, thermal conductivity and corrosion resistance. Also used for high temperature resistance. Magnesium nitride acted as a catalyst when cubic boron-nitride, a new material, was synthesized successfully for the first time.
    2. Additives in the production of high-strength alloy steel. Magnesium (Mg3N2) can replace desulfurized calcium in construction steel smelting, improving the density, strength, durability, and tensile strength of steel. Magnesium nitride can be used to desulfurize construction steel, and it is also a cost-effective way to do so.
    3. Preparation special ceramic materials
    4. Foaming Agent for Manufacturing Special Alloys
    5. Special glass is used to make.
    6. Crosslinking catalytic polymers
    7. Recycling of nuclear waste

    Hexagonal boron nitride, as a solid material, has incredible application potential in optics, biology and health sciences

    What is Hexagonal Borion Nitride? Hexagonal-boron Nitride (HBN) ceramics are essential microwave communication materials in aerospace. H-BN is a covalent compound that has a low selfdiffusion coefficient at high temperature and requires difficult sintering. It is most commonly prepared through hot pressing sintering. The hot pressing pressure and temperature can be very high. This makes it difficult to create complex-shaped ceramic products. Reaction sintering and high pressure gas-solid combustion are still options, but it is hard to get sintered products that are satisfactory in size and shape. Following mechanochemical activate with hexagonal Boron Nitride Powder, press-free sintering was done on H-BN ceramics in order to achieve 70% of the AlN ceramics' relative density.
    The characteristics and applications of hexagonal Boron Nitride
    Hexagonalboron nitride is a solid material that has amazing potential to be used in optics, biology, and other health sciences. This attracts more and more attention from around the globe. Professor Bernard Gil (National Centre for Scientific Research), as well as Professor Guillaume Cassabois from the University of Montpellier made important contributions to the physics of this fascinating material and to its ability to interact and control electromagnetic radiation. They have teamed up with James H. Edgar, Kansas State University USA to examine the use of hexagonal boron nutride in developing quantum information technologies. Professor Edgar has been working on advanced technologies to make high purity boron Nitride crystals.
    Hexagonalboron Nitride (hBN), a versatile solid material, plays an important role in many traditional applications. It can be used for lubrication, cosmetic powder formulations, thermal control, neutron detection, and other purposes. HBN, which was originally synthesized in 1842 from a fragile powder, has a layered structure that is different than graphite. This includes tightly bound B, N atoms that are superimposed in a network plan of weak interactions. A similar process can be used to make graphene from graphite, and monolayers of hBN. hBN actually sits at the intersections of two worlds. It is widely used in shortwave, solid-state light sources as well as layered semiconductors such a graphene and transition metallic halogens. Nevertheless, hBN exhibits distinct properties from both these classes of materials making it a potentially widespread candidate material.
    HBN crystal growth
    Since 2004, the field of hBN research and its application has seen a breakthrough in the form of new techniques to grow large (11.2 mm3) hBN single-crystals. Kansas State University's Professor Edgar and his colleagues have been key players in this area. They investigated the factors that influence the growth of crystals, their quality and eventual size, as also the effects on doping impurities or changing the boron ratio. HBN crystals are formed from solutions of molten elements, such as chromium or nickel, and can dissolve boron. Professor Edgar and collaborators demonstrated crystals made of pure boron have a higher quality than crystals made with hBN powder. They also examined the effects of gas composition, metal solvent selection, and crucible type upon the growth process.
    Additionally, the research team developed new techniques to produce isotopically pure HBN crystals. Natural boron can be described as a mixture of two isotopes, either boron-10 (20%) or boron-11 (80%). Although they have different nuclear masses, the chemical properties are identical and produce an indistinguishable structure for hBN. However, the LATTICE (or hBN) of an isotope has a significant effect on its vibration modes. These are also known as Phonons. Crystals with boron-10 or boron-11 have longer phonon lifespans. The crystal structure's random distribution of boron Isotopes causes phonon modes and their lifetime to disperse faster. The hBN has only one boron Isotope. Phonon scattering is decreased and the lifetime of phonons is extended. This reduces the hBN's thermal conductivity and makes it more efficient at dissipating warmth. Its optical characteristics are also very important, particularly in the field nanophotonics. This is the study of light reduced to dimensions below free space wavelengths. In this instance, the wavelength of light for h10BN has been reduced by 150.
    Quantum and HBN Information Technology
    Modern quantum technology relies on the ability of individual photons to be generated and manipulated. Single-photon sources emit light, unlike traditional thermal sources like incandescent lamps or coherent sources like lasers. These single-photon source emit light in the form single quantum particles (photons). They interact with other photons and can be used for storage and generation of new information in quantum computing. In some cases, single-photon source can be a defect in crystal structures caused by impurity and atoms. In the case hBN, the possibility of a high-density defect combined with a large range provides an opportunity for a support single-photon source. Quantum applications are significantly more spectral than pure nanophotonics, as they require higher sample purity.
    Photoluminescence experiments with hBN samples containing C and Si impurities showed that the spectral characteristics are significantly higher at 4.1eV light energy than pure hBN. Single-photon emission has been reported in recent cathode luminescence studies (in which phonon emissions are induced by an electronic beam), but it is not observed in laser-induced emit (photoluminescence). In photoluminescence experiments, many spectral lines lower than 4 eV have been seen. These may be due to single-photon emission defect in this energy range. These defects are still controversial. Although the phenomena of single-photon emitting hBN is complicated, the research of Professors Edgar Gil, Cassabois and Cassabois provides solid evidence of the extraordinary capabilities of this material in the field quantum technology.
