Needle silicon ash powder by the silicon ash storage powder grinding of silicon ash powder processed with high length to diameter ratio (15 - part) with wollastonite has a fibrous, acicular structure, color bright white, natural low iron, sulfur, phosphorus excluding water of crystallization, high melting point, corrosion resistance, ageing resistance, small thermal expansion coefficient, high refractive index, good reinforcement, sealing, heat resistance, abrasion resistance and stability characteristics.Can replace fiber talc, asbestos, glass fiber, etc.Acicular wollastonite powder is widely used in industry and agriculture.
Wollastonite can be used as the main raw material in cement, which can enhance the toughness and compressive strength of cement, improve the durability and impermeability of cement. At the same time, wollastonite can also be directly used in concrete, greatly improving the durability and mechanical strength of concrete
Wollastonite is one of the important components of ceramic raw materials, which can improve the strength, toughness, wear resistance and fire resistance of ceramics, and is widely used in ceramic building materials, daily necessities, industrial ceramics and other fields.
In the production process of glass products, wollastonite can be used to adjust the proportion of glass components, improve the transparency and strength of glass, but also can play a role in fire and heat insulation, is widely used in glass bottles, glassware, glass fiber and other fields.
Wollastonite is one of the important chemical raw materials, can be used to manufacture silicon dioxide, aluminum hydroxide and other important chemicals, but also can extract silicone oil and other organic matter, is widely used in chemical products, pharmaceuticals, agriculture and other fields.
Wollastonite can be used to make refractory materials and high temperature insulation materials, can withstand high temperature and chemical corrosion, widely used in steel, casting, metallurgy and other fields. At the same time, wollastonite is also used to extract non-ferrous metals and alkali metals and other minerals, and is widely used in mining, metallurgy, chemical industry and other fields.
MORE APPLICATIONS:
1). Improve stretching intensity
As the content of silicon ashstones increases, the tensile strength is increasing. According to experimental data, the thinner the number of meters of silicon ashstones, the better the tensile strength.
2). Improve bending
Adding 30%silicon ashstones to PA, the curved strength and bending modulus are significantly improved. This is mainly due to the characteristics and rigidity of the cashmelite, which makes it obvious technical advantages in sheets, plates, film, plastic products, etc.
3). Improve stability
The contraction rate of PA and PP is about 1-2%, and after joining the mineral fiber, the contraction rate can be significantly reduced. Adding an appropriate amount of mineral fiber during the manufacturing process of precision injection plastic parts and large plastic products can effectively maintain plastic products effectively The size stability can also shorten the processing cooling cycle.
4).improve resistance
Silicon ash has a special needle -shaped structure and unique physical and mechanical properties, which can greatly enhance the friction and heat resistance of the finished product.
5). Improve thermal change temperature
Add 30%silicon ashstone, and the thermal deformation temperature increases from 105ºC to 177 ºC, an increase of up to 70ºC.
