1) Whiteness: 93 ~ 97 %. 2) Viscosity ~ 74 % ; good dispersion. 3) Rub - resistant test : Value 3.6 mg / 2000 times.
Calcine kaolin
A) the main advantages
1. Kaolinite because of high purity and low content of harmful elements, not only process so easy, and high brightness Products, the average brightness can reach 93 percent, the maximum brightness can reach 97% for paper-making can improve Tu cloth paper whiteness, some substitute for titanium dioxide, can reduce costs.
2. Visco at high concentrations, up to 74%, good dispersion, and natural and synthetic adhesives and other additives formulations have good compatibility, can paint with good rheological properties, especially suitable for coating machine, etc. with high solid content coating machine use
3. Wear low-value materials, supplies, uniform heating will not lead to local over-burning, have been tested only wear value 3.6mg/2000 times.
B) the main application areas
1. Paper, paint can replace some of the expensive titanium dioxide.
2. Paint, water-based latex paint
3. Rubber reinforcing agent and special cables, industrial plastic functional filler, printing ink, food, medicines, cosmetics packing.
4. Advanced high brightness and special porcelain ceramic raw materials.
