Wollastonite Applications
1) Coating Grade Wollastonite Powder
With a good reinforcement, it can not only improve the toughness and durability of the coating, but also maintain the flat and good gloss of the coating surface. In addition, it improves the resistance to washing and anti-windy. It can also reduce the amount of oil absorption of coatings and inks and maintain alkaline, and has the ability to resist corrosion. You can get high-quality coatings with high-quality colors, and have good equalization and anti-aging performance. The coating can get better mechanical strength, increase durability, enhance adhesion and corrosion resistance. There are also good coverage and adhesion.
2) Plastic Rubber Grade Wollastonite
It has unique needle-like fibers, good insulation, abrasion resistance, and high discounts. It is a better filling material for plastic and rubber products.Features and performance: Wollastonite powder can improve impact intensity, enhance liquidity, and improve tensile strength, impact strength, linear stretching and mold contraction rate.
3) Paper Grade Wollastonite
Due to its unique needle-shaped structure, wollastonite mineral fiber can replace some plant fiber for the papermaking industry. The price of mineral fiber is far lower than the price of bleaching wood pulp. It can use it to replace part of the wood pulp, which can improve the strength of paper, save resources, reduce costs, and generate obvious economic, environmental protection, and social benefits.
Fiber-shaped silicon bellies are more suitable for replacement of traditional fillers such as news paper, rubber version paper, writing paper and other printing culture paper. Entering the breakthrough point in the field of papermaking.
Due to good characteristics that have good size stability, heat resistance, anti-chemical, flame retardability, and electrical insulation, the addition of fiber wollastonte stones in the poverty will give some special performance of paper on paper It can be used to produce special paper.
And because the modified siliconite has a special fiber structure, it will not seriously affect the mechanical strength of the paper after filling the pulp, so that it can also be used in some paper species with higher mechanical strength requirements. In addition, this will also become the main research direction and development direction of fibrous wollastonite.
After a special processing process, it can still maintain its unique needle -shaped structure, so that white sheet paper with wollastonite powder is added, which improves its whiteness, opaque (surface layer cover), flatness, smoothness, adaptability, reduction, reduction.Quantitative horizontal differences and cardboard wet deformation, improve printing adaptability, and greatly reduce the amount of other various raw materials, and overall reduction of paper products costs.
4) Building materials level wollastonite
It is a kind of non-toxic, tasteless, and radioactivity. It has gradually replaced the asbestos that is harmful to human health, and has become a new raw material for environmental protection building materials in the new century. After a special processing process, its unique needle-shaped structure can be maintained, so that the impact, anti-bending strength, and abrasion resistance of silicon calcium calcium plates, fireproof boards and other materials with wollastonite-like powder are greatly improved. In the field of architectural materials, wollastonite stones will be more widely used.
5) Ceramic Grade Wollastonite
Adding an appropriate amount of wollastonite powder to the ceramic raw material can greatly reduce the firing temperature, shorten the firing time, and achieve a fast-fired at a time. A large amount of fuel saving, significantly reduced product costs; at the same time, improve the mechanical properties of the product, reduce the cracks and warmers of the product, increase the glaze gloss, increase the strength of the embryo, thereby increasing the product's qualification rate.
