Product Description

Product Description

Anhui Yuanchen Nano Silicon Nitride Ceramic Powder Si3N4 Manufacturer

Feature

1.High purity, small particle size distribution, high specific surface area
2.Insoluble in water,but soluble in hydrofluoric acid
3.A very important structural ceramic material and superhard material
4.Have features of lubricity, abrasion resistance,strong corrosion resistance and high temperature oxidation resistance.
5.Can resist thermal shock.When heated in the air to more than 1000ºC,it will never rupture with cold snap and severely heating.
6.Silicon nitride ceramic devices have low ceramic temperatures,with good dimensional stability and high mechanical strength.

 

Precautions

This product should be stored in a cool, dry room to avoid heavy pressure.Powders that have not been surface treated should not be exposed to air to avoid moisture absorption and agglomeration, which may affect dispersion and use.

Company Introduction



YuanChen Environmental Science and Technology Co., Ltd, was founded in 1997, formerly known as the Shanghai Yuan Chen Environmental Protection Equipment Parts Co, Ltd. Anhui Yuan Chen Environmental Science and Technology Co., Ltd. Was established in 2005, is a national high-tech enterprise, specialize in manufacturing baghouse filter components for air pollution control. The main products are PTFE fiber, filter media, filter sleeves & bags, filter cages, honeycomb SCR catalyst, associated items and filter cleaning systems.

Yuan Chen S&T is always committed to scientific and technological development, focusing on research and development capabilities, Two eternal experts who enjoys the benefits of the state council, six senior engineers and eight master consist of our professional R&D team. 38 granted patents including 10 invention patents, four high-tech identified products.

Our products are widely used for environmental projects such as steel, cement, chemicals, power utilities, refuse incineration, construction, grain processing, wood, &tobacco etc. Our market includes all of China, and we also export to Germany, Russian, Japan, Korea, South America, Europe, South East Asia and many other regions and countries.

The molecular structure of PTFE ultrafine powder is the same as that of polytetrafluoroethylene, except that its molecular weight is 30,000-200,000, the average particle size is 1-20 μm. The molecular weight of polytetrafluoroethylene is 1000,000-10000,000, and the average particle size is 25. ~800μm.

Physical properties of PTFE ultrafine powder Particle size, shape and specific surface area are the main factors affecting the performance of ultrafine powder.

 

1. Maintains the excellent properties of PTFE, also has many unique properties, such as high crystallinity, good dispersibility, easy to mix and add

2. Widely used in the blending modification of polymer materials.

3. The addition of this product to engineering plastics can significantly improve the wear resistance, lubricity, non-stickiness and flame retardancy of the matrix material

4. The performance of the substrate is significantly improved.

5.YC-200 can be used as a processing aid between -190 °C and 300 °C

6. It can be used as a lubricant alone. 

7.It cannot be used to replace high-component PTFE suspension or dispersion resin for extrusion or compression molding.
