The use of wollastonite powder in coatings
Wollastonite is selected, crushed, and ground into fine powder by a wollastonite mill to obtain an ultra-fine powder of about 80-5000 mesh. Wollastonite powder is widely used in coatings, plastics, ceramics, construction , paper, fiber, glass and other industries, wollastonite powder has a large number of meshes, commonly used are 100 mesh, 400 mesh, 800 mesh, 1250 mesh, 3000 mesh, etc. :
First, the use of wollastonite in powder coatings
Incorporating wollastonite powder into powder coatings, because wollastonite has the characteristics of bright white, needle-like particle shape and low oil absorption, it can produce high-quality white and soft light-colored coatings, improve the toughness and durability of coatings, and maintain coatings. Smooth surface and good gloss and resistance to scrubbing and weathering, but also reduce oil absorption of paint and maintain alkalinity, with anti-corrosion ability. When wollastonite is used as filler or emulsion in paint, high-quality and bright paint can be obtained, and it has good leveling and anti-aging properties. White wollastonite is a good raw material for high-quality white paints and soft-toned paints. It is easy to paint, has a smooth surface, and has high weather resistance. Surface-treated, fine-grained, high-aspect-ratio wollastonite products have proven to be cost-effective functional fillers for a wide range of industrial and marine coatings. strength, increased durability, enhanced adhesion and corrosion resistance. Wollastonite products are also used in housing construction, roof tile materials and powder coatings. It can be used as a filler in the coating to reduce the amount of titanium dioxide. It has good anti-aging and anti-radiation effects, as well as good coverage and adhesion.
Wollastonite powder is used in anti-corrosion coatings, thermal insulation coatings, architectural paints, marine paints, electrical insulating paints, etc. With wear resistance, corrosion resistance, UV resistance; improve surface gloss, water erosion and buffer PH value performance; covering, incremental action, anti-cracking; anti-aging, prolong coating life; improve thermal stability; reduce bonding substances consumption
