What's the use of wollastonite powder in coatings?How do you use it?
Also found in certain deep metamorphic rocks: used as raw materials or fillers for paper making, ceramics, cement, rubber, plastics, gas filtration materials and heat insulation materials, metallurgical fluxes, etc.
Coating wollastonite powder has a good reinforcing effect, which can improve the coating toughness and durability, and can keep the paint surface smooth and good gloss. But also improve the washing resistance and weathering resistance performance, but also can reduce the amount of oil paint and ink and alkali, has corrosion resistance. High quality color bright paint is obtained, and has good levelling property and aging resistance. The coatings can get better mechanical strength, increased durability, enhanced adhesion and corrosion resistance. There is good coverage rate and adhesion.
Ca3 Si3O9. Three triclinic. Usually flaky, radial or fibrous aggregates. White grayish. Glass luster, pearl luster. Cleavage surface hardness of 4? 0. parallel cleavage {100}, {001} parallel medium, two groups of angle is 74 degree. The cleavage surface density of 2? 78 ~ 91 g / cm 3. is mainly produced in contact metamorphic intrusive rocks and limestone belt as the main mineral component of skarn.
