What is Zinc Sulfide

Zinc Sulfide:

Its chemical formula is ZnS. Its molecular weight, 134.72. It is created by interacting through ionic interactions with zinc ions, (Zn2+), and sulfur ions, (S2-). In the crystal, the sulfur ions form a regular tetrahedron with the zinc ion in the middle. The sulfur ion occupies the center of the tetrahedron. This structure can also be described as a face centered cubic crystal system where zinc and sulfur are respectively located in the vertex of the lattice and at its face center.

Zinc Sulfide (also known as Zinc Sulfide) is an insoluble, white solid. It is not soluble in water. However, it is soluble with bases and acids. Zinc sulfide's density is 3.98 g/cc, with a melting point of 1350 degrees C. and a boiling point of 1650 degrees C. It is also transparent and has good optical properties. The light transmission is between 200 and 400nm. Its chemical properties are stable but under certain circumstances it can also change. zinc Sulfide is oxidized by an oxidizing substance to produce zinc sulfate. In an environment that is alkaline, zinc sulfide will react with hydroxide molecules to produce zinc hydroxide.

What is the role and mechanism of water

We often see concrete used on construction sites and in home improvement. However, you may not know that adding a water-reducing agent to concrete is a very important step. So, why do we need to add a water-reducing agent to concrete, and what is the function and mechanism of this additive? Next, we will reveal the answers for you.

First of all, let us understand what is water water-reducing agent.

Water reducing agent is a chemical additive, and the main component is a surfactant. It can greatly reduce the amount of water required for concrete, thus improving the strength and durability of concrete. Using this additive can save the amount of cement, reduce the cost of concrete, and improve the quality of construction.

So, what's the purpose and function of the water-reducing agents?

Particularly, they include the following elements:

1. The effect of surfactants on water is reducing The surfactant that is contained in this water reducing ingredient may be applied to the surface of cement particles, causing them to become more dispersed, thereby reducing the demand for water in the concrete.

2. Dispersing effect Water-reducing agents will make the water within the concrete spread more uniformly, which can prevent the possibility of drying locally and settling.

3. Reduced water-water absorption: These agents reduce the amount of pores present in concrete, thereby improving its permeability and endurance.

The development history of water-reducing agents:

1. The first generation of water-reducing agent

Ordinary water reducing agent (water reduction rate 8%), also known as plasticizer; the main representative of the lignosulfonate system (sodium lignosulfonate, calcium lignosulfonate, magnesium lignosulfonate, etc.).

2. The second generation of water-reducing agent

High-efficiency water-reducing agent (water reduction rate 14%), also known as superplasticizer; the main representative of the naphthalene system, melamine system, amino sulfonate system, and aliphatic system.

3 .Third generation water reducing agent

High-performance water-reducing agent (water reduction rate 25%); the main representative of polycarboxylic acid water-reducing agent, which can be divided into early-strength type, standard type, and slow-setting type.

In short water-reducing agent play an important role in concrete. It will not only increase the durability and strength of concrete, but also reduce concrete needed and cut costs. This is why water-reducing agents are an essential chemical ingredient in construction.

Micro-porous PVC-SiO2 Separator for Gelled Lead-acid Battery

PVC and SiO2 Separators PVC separators that are made by wet processing are mostly used in lead-acid sealed gel batteries. PVC-SiO2 Separators have higher porosity and more uniform pore sizes than sintered PVC Separators, as well as better puncture and compressive resistance, greater toughness and better compression strength than glass fibre separators. It has better chemical stability and oxidation resistance than polyethylene PE.

PVC and SiO2 Separator Properties:

1. The PVC/SiO2 separator is characterized by high porosity, a small maximum pore, and high liquid absorption. These characteristics allow the separator to retain the electrolyte easily, and have a rapid penetration rate.
2. The wet elastic is strong and can provide electrolyte to the plate while keeping the ion conductivity unblocked.

3. The "acid-strategization" phenomenon can be effectively prevented by a battery with strong liquid transfer abilities.

4. Based on the glass fiber. By adding organic fibers, the PVC/SiO2 separation is enhanced in terms of tensile strength and other performance indicators.

Application of the PVC-SiO2 separation in batteries:

1. The positive and the negative plates are placed close to each other, but should not be in direct contact. A separator between the plates is used. The PVC-SiO2 should be porous to allow electrolyte into the separator, and have good acid resistance and alkali tolerance. Wood, microporous Rubber, Microporous Plastic, and Resin-impregnated Paper are all good materials for separation.

2. The battery separator is responsible for carrying the electrolyte containing sulfuric acid in the cell. In the lean state, the separator shares the entire amount of sulfuric acid needed to meet the rated battery capacity with the electrode plate. For this to work, the separator needs to be large enough to absorb the sulfuric acids. Also, the battery must have enough space to accommodate the separator.

3. The PVC-SiO2 separation should provide sufficient oxygen channels to allow the oxygen that precipitates from the positive plate to pass through it to the negative, where it can be converted into oxygen. cycle. The separator must have a reasonably microporous surface, and the acid saturation of the separator must be determined at the time the battery is being designed.

4. The separator is used in lead-acid batteries with valve regulation to prevent the active material from falling off of the electrode plates and to keep the electrode plates from deforming. This prolongs the service life. It is necessary that the separator shrinks after being injected with sulfuric acid.

5. The internal resistance of a battery includes the resistance of a battery separator as well as the resistance that is formed when the separator contacts the plate. It is necessary that the separator has a low resistance and also be put under greater pressure when designing the battery. So, the PVC/SiO2 separation is in contact with the poleplate, and resistance is reduced at this point.

Tech Co., Ltd. is a professional PVC-SiO2 Separator With over 12 year experience in chemical product research and development. We accept payments by Credit Card, T/T (wire transfer), West Union, Paypal, and T/T. The goods will be shipped to overseas customers via FedEx or DHL.

The product of the quartz mine is referred to by the term below 120 mesh. Quartz powder has more than 120 different products as their destination.
What are the uses of quartz powder?
Quartz is one the most important minerals on the surface of the Earth. Quartz Powder has many uses in industry.

Rich quartz sand used in glass making. Quartz sand plays a key role in the production of instrumentation, flat-sheet, specialty, and fiberglass glass. Quartz can also be used to produce lenses for optical instruments such as telescopes and microscopes. It is also used in prisms, sensors and electronic and scientific instruments.

Quartz Powder as an Abrasive. Because of its high hardness, which is seven on the Mohs scaling, quartz powder is more durable and effective than many other natural substances. Quartz powders and finely ground oxides have many uses, including sandblasting media, scouring cleanser, grinding media, grit, and sanding for sawing and sanding.

Quartz Powder used in the Slab Industry. Quartz Grains and powder are also used to produce artificial marble slabs. Since the very beginning, we are producing the highest-quality products for this industry.

Other Uses for Quartz Powder: You can use quartz powder as a filler when making rubber, putty, or paint. The sized and screened quartz grains can be used for roofing granules or as filter media. Quartz Powder is used to provide traction in the railroad and mining industry. These sands can be found on beaches, golf course sandboxes and volleyball courts.

Quantum Powder for Investigation of the Properties of Engineered Cementitious Composites Reinforced by Fibers
ECC mixes are more workable when they contain quartz powder and silica dust. These materials can absorb water. Water absorption is lower for cement and quartz than silica. Silica fume, however, has a specific area of between 15,000-30,000m2/kg. The use of water is constant in all ECC mixtures. In essence, these conditions may be the cause of the poor workability of ECC mixes. However, by adjusting superplasticizer content (SP) for each mix, a good consistency and working ability of ECC mixes can be achieved.

In the case of PVA fiber-based ECCs, adding quartz powder can improve the average compressive force of 6.85% or average strength ratio of 1,0685 compared to PVA fiber-based samples with no quartz powder. The addition of quartz to steel fibers based ECC can improve the average compressive strengths of 8.09% and the average strength ratios of 1.0809, compared with the steel fibres based ECC samples that do not contain quartz powder. The addition of the quartz powder to the steel fibers and PVA ECC samples led to higher compressive strengths with an average strength of 1.0747 when compared to samples of FR ECC without quartz.

Properties and Applications of Quartz Powder

What is quartz?

Quartz powder is also known by the name silica. Quartz sand has a high chemical stability and is hard. Its main component is SiO2. The quartz sand color is translucent or milky white. Hardness 7; brittle with no cleavage. Shape fracture, grease-luster, density of 2,65, bulk density (20 to 200 mesh is 1,5), chemical, mechanical, and thermal properties are clearly anisotropic, it's insoluble in acids, but slightly soluble in KOH solutions, melting point 1650. Quartz sand is the result of processing the quartz stone from the mine. It has a mesh size less than 120. The products with a mesh greater than 120 are known as quartz powder.

Use of quartz powder

Mineral fillers such as non-metallic minerals are used in modern polymer products like plastics, rubber and coatings. Addition of non-metallic minerals, such as the quartz powder, to the polymer material base can reduce costs, but also improve performance and dimensional stabilty, while giving the material special chemical and physical characteristics. Compression resistance, impact and corrosion resistance, fire retardancy, insulation etc.

KMPASS, etc. SlEC, a high-pressure epoxy molding material with good weather resistance and excellent electrical properties was developed using silicon micropowder. It is the best material to use for high voltage insulators and switches. KMPASS et al. Quartz powder was added to the patent of flame-retardant coatings in order to improve their thixotropic qualities. The coating features uniform coating, no cracked, quick curing, and low costs. Liu You and other researchers added quartz to epoxy resin in order to develop an epoxy coating that is non-toxic and has anti-corrosion properties. It overcomes existing coating's shortcomings when it comes to brushing or spraying. KMPASS, etc. In the patented electronic insulation sealing film prepared by using butyl as the base material, adding silicon powder to it, the film has high strength insulation, is waterproof, resistant to heat, cold, chemical corrosion, ageing resistance, good plasticity and insulation.
