What is quartz silica powder?

Due to various environmental factors, hollow glass microspheres are becoming more popular. They are an efficient way to decrease the production of greenhouse gases (GHG), in addition to their use for environmental remediation. Many countries have adopted policies that help reduce the impact of these greenhouse gases. For example, the United States has several states that have pledged to cut their GHG emissions by implementing executive actions plans.

What's quartz silica powder?

Quartz Silica Powder (QSP), a silica powder, is an extremely pure natural silica. This powder is nearly 99.7% SiO2 in a white color. It is extremely durable and can withstand heat and chemicals.

You can find it in rocks, soil and sand. It's a safe mineral to eat because it is breathable. It can withstand high temperatures, acid, corrosion, impact and bending. You can find it in powder form or as sand.

Quartz can be used for jewelry and plastics. Quartz's strength, high melting point and refractoriness make it a great filler in a wide range of products. This material is also useful in jewelry, gemstones and construction. Because of its strength, it is used to make bricks and watches. This metal is widely used in glass, cement and iron & steel industries.

Quartz crystal, a form of mineral composed silica or silicon dioxide is one type. Quartz crystal is common on the Earth's surface and the second-most common mineral within the crust. You can find it in rock formations, such as pegmatites or hydrothermal veins. Quartz crystals, in their purest form are completely colorless. Their color can be affected by impurities.

Quartz powder is found to have a very small particle size according to SEM. Quartz powder particles are very small and range from 0.15 to 1.15 Microns.

What is the use of hollow glass and glass microspheres?

Hollow glass microspheres can be described as a form of glass particle that has low specific gravity. They can be used for a wide range of purposes and have good heat resistance and thermal conductivity. They also have a low dielectric factor, so they can be used for applications that need low dielectric factors.

You can make these spheres from different materials like silica or multi-oxide. While pure silica microspheres are the most common, it is possible to manufacture them using a proprietary Borosilicate-Sodalime glass blend. Microspheres can also be made from silica and zirconia. Surface tension effects allow for almost perfect spherical forms.

Because of their unique abilities, hollow glass microspheres are an ideal vehicle to transport a wide range of therapeutic agents. They are able to encapsulate delicate drugs and extend their stay in the stomach region due to their shape. A uniform area can help reduce drug release.

Although hollow glass microspheres can be used for a variety of purposes, their chemical composition, sizes, and textures are all different. While some are made from glass, others are made out of plastic. Certain microspheres can be more vulnerable to chemical reactions and heat damage than others. These properties can be affected by the manufacturing process or the final use of the product.

A hollow glass microsphere's other important characteristic is its low density. This microsphere can be used for extending the properties liquids or resins. Solid glass microspheres have a disadvantage: they don't have the same low density as hollow glass microspheres. Their higher density may improve their physical properties. Potters Industries uses 30% solid glass microspheres or higher in its products to reduce warpage.

The Decisive Parameters of Solder Paste Quality Are Revealed

Tin powder and auxiliary composition SMT manufacturing relies on quality solder paste printing. Many factors affect the quality of solder paste's printing. It is important to know the properties of solder dust and how much solder powder you have to make solder paste melt. This will also affect the printing speed, printability, weldability, and quality of the solder joints. The eutectic temperature of tin powder-alloy components should be as close as possible to the eutectic. It is calculated as the proportion of flux and tin in paste. Tin powder content directly influences the viscosity, printing and durability of solder paste. In general, the content of tin powder is 7590%. Tin powder is 75 to 90% in general. It is used for template printing and no-cleaning solder paste. The content of the tin used in drip coating is 75 to 85 p> The size, shape and distribution of the Tin powder particles It is important to consider the size, shape, and uniformity of the tin powder particles in order to influence the properties. It is best to use smaller particles for solder paste printing, particularly when using high density products that have a narrow spacing. About 1/5th of the opening size for a template is used to measure the particle diameter. While the pattern of solder paste printed with small particles alloy powder is very detailed, edge collapse can easily be caused by it. The potential for oxidation is greater due to small particles' large surfaces. If the assembly density of the powder is low, it's possible to choose a coarser alloy powder without having an impact on the printing ability. This can improve both the weldability as well as reduce the price for solder paste. Also, the form of the alloy powder can impact the paste’s printingability and desorption as well as weldability. Spherical-particle alloy paste has good printing properties, low viscosity and easy to collapse after printing. This makes it ideal for printing metal templates and narrow spacing screens. Because of their small size, high oxygen content, and bright welding spots, spherical particle alloy powder improves welding quality. At present, however, they are mostly used.

Viscosity

Solder paste, a fluid that is highly thixotropic can be made to flow by external forces. It is the most important characteristic of solder paste. Viscosity can affect the performance of printing. Viscosity determines how easy it will be to get out of the template. The percentage of tin in the paste also influences the viscosity. A large percentage of flux indicates a lower viscosity.

Oxide Powder

Titanium Oxide TiO2 powder CAS 13464-67-7

About Titanium Oxide TiO2 powder:
Titanium Oxide TiO2 powder, also known as Titanium dioxide, is an important inorganic chemical pigment, mainly composed of Titanium dioxide. The titanium dioxide production process has a sulfuric acid method and chloride method of two process routes. It is widely used in coating, printing ink, paper making, plastic and rubber, chemical fiber, ceramics and other industries.

Among the commonly used white pigments, the relative density of titanium dioxide is the smallest, and the same mass of white pigments, titanium dioxide has the largest surface area and the highest pigment volume. The chemical properties of titanium dioxide are very stable, are a kind of acidic amphoteric oxide. Almost no reaction with other elements and compounds at room temperature, on oxygen, ammonia, nitrogen, hydrogen sulfide, carbon dioxide, sulfur dioxide are not effective, insoluble in water, fat, dilute acid and inorganic acid, alkali, only soluble in hydrofluoric acid. But under the action of light, titanium dioxide can take place a continuous REDOX reaction, has the photochemical activity. This kind of photochemical activity, under ultraviolet radiation anatase type titanium dioxide, is particularly obvious, this property makes titanium dioxide is some inorganic compounds of the photosensitive oxidation catalyst and some organic compounds of photosensitive reduction catalyst.

Titanium dioxide has Rutile type (Rutile R type) and Anatase type (A-type) two kinds of structure, Rutile crystal structure is dense, relatively stable, small optical activity, so good weather resistance, at the same time has A higher hiding power, color extinction. Titanium dioxide has semiconductor properties, its electrical conductivity increases rapidly with temperature, and it is also very sensitive to hypoxia. The dielectric constant and semiconductor properties of rutile TiO 2 are very important to the electronic industry, which can be used to produce electronic components such as ceramic capacitors.

According to Mos hardness scale of 10 points, rutile TiO2 is 6 ~ 6.5, anatase TiO2 is 5.5 ~ 6.0, so in chemical fiber extinction in order to avoid wear spinneret hole and use anatase. Although titanium dioxide has hydrophilic, its hygroscopicity is not too strong, rutile type is smaller than the anatase type. The hygroscopicity of titanium dioxide has a certain relationship with the size of its surface area, large surface area, high hygroscopicity, but also related to the surface treatment and properties. Feel free to send an inquiry to get the latest price if you would like to buy Titanium Oxide TiO2 powder in bulk.

How is Titanium Oxide TiO2 powder produced?
Titanium dioxide was manufactured in two different ways: Sulphate Process and Chloride Process.
1.Sulphate Process
Titanium sulfate is produced by acidolysis of iron titanium powder and concentrated sulfuric acid. The concentrated sulfuric acid is decomposed into metantitanic acid, which is then calcined and crushed to obtain titanium dioxide products. This method can produce anatase type and rutile type titanium dioxide. The sulfuric acid method has the advantages of low price and easy to get ilmenite and sulfuric acid as raw materials, more mature technology, simple equipment, easy to solve anti-corrosion materials. Its disadvantage is that the process is long, can only be based on intermittent operation, wet method operation, high consumption of sulfuric acid, water, waste and by-products, large pollution to the environment.
2.Chloride Process
The chlorination method is to use titanium-containing raw materials, high titanium chloride slag, or artificial rutile, or natural rutile and chlorine gas reaction to produce titanium tetrachloride, distillation, and then gas-phase oxidation; After rapid cooling, TiO2 was obtained by gas-solid separation. The TiO2 adsorption due to a certain amount of chlorine needs to be heated or steam treatment to remove it. The process is simple, but at 1000℃ or higher conditions of chlorination, there are many chemical engineering problems such as chlorine, chlorine oxide, titanium tetrachloride high corrosion need to be solved, coupled with the special raw materials used, compared with the sulfuric acid method cost. Chlorination process production is continuous production, the production equipment operation flexibility is not large, but its continuous process production, the process is simple, fewer process control points, product quality is easy to achieve the optimal control. The advantages of the chlorination method are short process, easy expansion of production capacity, a high degree of continuous automation, relatively low energy consumption, and high-quality products can be obtained. Its disadvantages are a large investment, complex equipment structure, high material requirements, high-temperature resistance, corrosion resistance, device maintenance is difficult, research and development is difficult.

Application of Titanium Oxide TiO2 powder:
The most important applications of titanium dioxide are paints, varnishes and paper and plastics, which account for about 80 percent of world consumption of titanium dioxide. Other pigment applications, such as printing inks, fibers, rubber, cosmetics and food, account for another 8%. The rest is used for other applications, such as industrial pure titanium, glass and glass-ceramics, electroceramics, metallic copper, catalysts, electrical conductors and chemical intermediates.
1. Titanium dioxide is the most widely used white pigment because of its brightness and high refractive index.
2. Titanium dioxide is also an effective sunscreen in powder form, where it is used as a pigment to provide whiteness and opacity to products such as paints, coatings, plastics, paper, inks, food products, pharmaceuticals (such as tablets and tablets) and most toothpaste. In painting, it is often abbreviated as "vivid white", "perfectly white", "whitest white" or other similar terms.
3. Titanium dioxide in the rubber industry as a colorant, but also with reinforcing, anti-aging, filling the role.
4. In white and color rubber products to add titanium dioxide, under sunlight, sun resistance, no cracking, no discoloration, stretching rate and acid and alkali resistance.
5. Titanium dioxide for rubber, mainly used for automobile tires, rubber shoes, rubber floor, gloves, sports equipment, etc., generally anatase type.
6. For automobile tire production, often add a certain amount of rutile titanium dioxide products, to enhance the ability to resist ozone and ultraviolet.
7. Titanium dioxide is also widely used in cosmetics. Because titanium dioxide is non-toxic, far superior to lead white, almost all kinds of powdered titanium dioxide replace lead and zinc white.
8. Only 5%-8% of titanium dioxide powder can be added to the permanent white so that the spice is more slippery, adhesion, absorption and hiding power.
9. Titanium dioxide in gouache and cold cream can reduce the greasy and transparent feeling.
10. Titanium dioxide can also be used in a variety of other spices, sunscreen, soap, white soap and toothpaste.
11. When deposited as a thin film, the refractive index and color of titanium dioxide make it an excellent reflective optical coating for dielectric mirrors.
12. Some grades of modified titanium-based pigments used in sparkling paints, plastics, topcoats and cosmetics - these are artificial pigments whose particles have two or more layers of various oxides (usually titanium dioxide, iron oxide or alumina) to produce a shimmer, iridoid and/or pearlescent effect.
13. Titanium dioxide is used as a pigment, sunscreen and thickener in cosmetics and skincare products in sunscreen and UV protection pigments.
14. As a sunscreen, ultrafine TiO 2 is used, which is notable for its combination with ultrafine zinc oxide and is considered to be an effective sunscreen that reduces the incidence of sunburn and minimizes premature photoaging, photocarcinogenesis and immunosuppressive sun exposure associated with long-term excess. Sometimes these UV-blockers are used in combination with iron oxide pigments in sunscreens to increase protection against visible light.

Storage Condition of Titanium Oxide TiO2 powder：

Nanocolloid Gold Immunolabeling Technology

An overview of the immunocolloidal-gold technology Technology based upon immunocolloidalgold (often known as "colloidal") is used as a tracer in the detection of antigen antibodies. The colloidal gilded by Faulk equals 1971 immunochemical introduced a colloidal gilded method to determine the human chorionicgonadotropin. This technology has become very popular in areas such as medical clinical inspection, food security inspection and animal epidemic monitoring. Coloidal gold immunofiltration (CGI) and colloidal Gold immunochromatography (CGI) are two of the most popular and widely used techniques within the veterinary industry.

Coloidal gold immunolabeling technology

The colloidal gold, which is positively charged when placed in weak bases environment, can form an electrical bond with negatively charged proteins molecules. It does not alter the biochemical properties of the proteins. Due to the high amount of surface charge, colloidal silver particles are strong at binding proteins. To make colloidal silver proteins, you can noncovalently combine coloidal gold particles and staphylococcus A (SPA), toxin, immunoglobulins toxin, enzyme, drug, or hormone. If the markers are made from gold particles of high electron densities, visible pink spots could be formed when they aggregate at an antigen body reaction spot on the solid-phase carrier. Therefore, colloidal gold, as a marker, can be used in immunoelectron microscopy, conventional light microscopy, quantitative and qualitative studies of antigens, as well as qualitative or semi-quantitative rapid detection of antigens or antibodies in vitro immunochromatography.

Benefits of the colloidal-gold immunolabeling technique

Immunocolloidal-gold technology is stable and easy to preserve. It is possible to preserve the results of experiments for long periods. This operation is quick and easy. The results can also be easily observed and compared. It is as simple as immersing the strips into the specimen. After the immunoanalysis, the colloidal gold will be used to indicate the process of forming the color mark. The whole process takes between 3-10 minutes. It's not harmful to the operator. There are no radioisotopes and o-phenylenediamines that can pollute the environment or cause harm to operators in colloidal silver immunodetection. There is no harm in gold or silver, and there are no environmental pollutants. The commercial reagent doesn't require any instruments, which saves money, makes it easier to use, and allows for more field applications. Biomedicalmaterialsprogram (aka.

Carbide powder

Tungsten Carbide WC Powder Cas 12070-12-1

About Tungsten Carbide WC Powder:
Tungsten carbide is a compound composed of tungsten and carbon, with a molecular formula of WC and a molecular weight of 195.85.The most basic form of tungsten carbide is a fine gray powder, but it can be pressed into shapes through a process called sintering for use in industrial machinery, cutting tools, abrasives, armor-piercing bullets, and jewelry.

The stiffness of tungsten carbide is about twice that of steel, and Young's modulus is about 530-700 GPa (77,000 to 102,000 ksi), which is twice the density of steel and is almost between lead and gold. Its hardness is comparable to that of corundum (α-Al2O3), and only cubic boron nitride and diamond powder, grinding wheels and compounds with high hardness abrasives can be used for polishing and finishing.

Tungsten carbide is a black hexagonal crystal with metallic luster and hardness similar to that of a diamond. It is a good conductor of electricity and heat. Tungsten carbide is insoluble in water, hydrochloric acid and sulfuric acid, but easily soluble in a mixed acid of nitric acid and hydrofluoric acid. Pure tungsten carbide is fragile, and if a small amount of titanium, cobalt and other metals are added, the brittleness can be reduced. Tungsten carbide used as a steel cutting tool is often added with titanium carbide, tantalum carbide or their mixture to improve the anti-knock ability. Tungsten carbide is chemically stable. Tungsten carbide powder is used in cemented carbide production materials. Feel free to send an inquiry to get the latest price if you would like to buy Tungsten Carbide WC Powder in bulk.

How is Tungsten Carbide WC Powder produced?
Using metal tungsten and carbon as raw materials, tungsten powder with an average particle size of 3 to 5 μm and carbon black of the same amount are dry mixed with a ball mill, fully mixed, press-molded, and placed into a graphite plate, and then placed in a graphite resistance furnace Or it can be heated to 1400～1700℃ in an induction furnace, preferably 1550～1650℃. In the hydrogen stream, W2C is initially produced and continues to react at high temperatures to produce WC. Or firstly, tungsten hexacarbonyl is thermally decomposed at 650-1000°C in the CO atmosphere to obtain tungsten powder, and then reacted with carbon monoxide at 1150°C to obtain WC. Temperatures higher than this temperature can generate W2C.
Chemical reaction formula:
2W + C = W2C
W + C = WC
Tungsten trioxide WO3 is hydrogenated and reduced to prepare tungsten powder (average particle size 3～5μm). Then, the mixture of tungsten powder and carbon black in an equimolar ratio (dry-blended with a ball mill for about 10 hours) is press-formed under a pressure of about 1t/cm2. Put the pressurized material block into a graphite pan or crucible, and heat it to 1400～1700℃ (preferably 1550～1650) in a hydrogen stream (using pure hydrogen with a dew point of -35℃) using a graphite resistance furnace or an induction electric furnace ℃), carburizing will produce WC. The reaction starts from around the tungsten particles, because W2C is generated at the beginning of the reaction, and because the reaction is incomplete (mainly because the reaction temperature is low), unreacted W and intermediate W2C remain in addition to WC. Therefore, it must be heated to the above-mentioned high temperature. The maximum temperature should be determined according to the particle size of raw tungsten. For coarse particles with an average particle size of about 150 μm, the reaction proceeds at a high temperature of 1550 to 1650°C.
Chemical reaction formula:
WO3 + 3H2 → W + 3H2O
2WO3 + 3C → 2W + 3CO2
2W + C = W2C
W + C = WC

Propylene glycol phenyl ether CAS 770-35-4

About Propylene glycol phenyl ether:

When PPH is added to the latex system, it is redistributed in the aqueous phase and the polymeric phase. Its excellent film-forming efficiency depends on its minimal distribution coefficient in the two phases, while ensuring its good plasticizing effect and appropriate volatilization rate balance. PPH is a colorless transparent liquid with a mild odor. For the vast majority of latex and resin has a strong ability to dissolve, water solubility is small, to ensure that it is fully absorbed by latex particles, so as to give latex paint the best coalescence performance and color uniformity while having excellent storage stability.
