Method of changing the whiteness of talc powder
With the continuous improvement of product quality requirements of various industries, so people are looking for new ways to improve product quality, which is useful to change the whiteness of talcum powder to improve product quality, then, why is there such a way? How do we change the whiteness of talcum powder? Today we will discuss together.
1, the surface covering modification method: the surfactant covering the surface of ultrafine talc particles. The approach is now commonly used methods.
2, high-energy surface modification: the use of high-energy discharge, ultraviolet light, plasma rays and other huge energy generated by the surface modification of ultrafine talc particles.
3, the outer film layer modification: ultra-fine 1250 mesh talc particles surface uniformly coated with a layer of polymer.
4, deposition reaction modification: this approach is the use of deposition reaction on the surface of talc particles for coating.
5, mechanical and chemical methods: this approach is larger than the ultra-fine talcum powder particles after crushing, friction and other methods to make it smaller.
6, part of the active modification: the use of chemical reactions in the particle surface grafted on some compatible with the polymer groups or functional groups, so as to achieve the purpose of inorganic particles and polymer composite.
The above is currently known to change the whiteness of talcum powder methods, talcum powder can be widely used in papermaking, ceramics, coatings, cables, rubber, food, plastics and other industries, and play an important role in these industries. So changing the whiteness of talcum powder also becomes a way to improve product quality.
