煅烧高岭土

一、主要优点：

1.由于高岭岩纯度高，有害元素含量极低，所以不仅处理工艺简单，而且产品白度高，平均白度可达到93%，最高白度可达到97%，用于造纸可提高涂布纸的白度，部分代替钛白粉，可降低成本。

2.粘浓度高，可达74%，分散性好，并与天然和合成胶粘剂以及配方中其他助剂都有很好的相容性，可使涂料具有很好的流变性能，特别适于机内涂布等要求固含量高的涂布机使用

3.磨耗值低，物料受热均匀，决不会出现局部的过烧，经测试磨耗值仅3.6mg/2000次。

二、主要应用领域

1．造纸、涂料可替代部分昂贵的钛白粉。
 2．油漆、水性乳胶涂料

3．橡胶及特种电缆补强剂，工业塑料功能填料，油墨、食品、药品、化妆品填料。
 4．高白度高级瓷器及特种陶瓷原料。

Calcine kaolin 
一、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.
二、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.
