工业沉淀（轻质）碳酸钙
Technical precipitated (light) Calcium
carbonate |
|
本品为极细白色粉末，不溶于水。优质石灰石经高温煅烧，经化学反应、过滤、干燥、筛粉等工艺制作。比重轻，广泛用于橡胶、塑料、建材、造纸和涂料等工业中的填充剂。
This product is very fine white powder,
not dissolved in water. The high quality limestone is burned by high
heat, through the chemical reaction,
filtration, drying, and sieving to reach the finished
product. It is with the low density. This product is widely used as stuff in
rudder, building material, paper, and paint. |
