硅酸钙 Calcium Silicate

产品特点：                                                                                                                                                                         

1、在橡胶中的应用
用于橡胶中，可增加橡胶的体积，改善橡胶的加工性，起半补强或补强作用，并可调节橡胶的硬度及回弹性。
2、在塑料中的应用
塑料工业是硅酸钙最大的消费领域，细化的重钙粉，能明显提高塑料复合材料界面的强度及力学性能。塑料中使用微细硅钙粉，既可降低其制造成本，又可提高其性能。
3、在造纸中的应用
造纸工业用硅酸钙主要有两个用途，一是作为填料，二是作为涂层。目前，我国大多数造纸厂使用的是酸法造纸工艺，采用的填料主要是高岭土和滑石粉，硅酸钙会取代酸式施胶，重钙粉作为填料将在很大范围内代替滑石粉或高岒土。
4、在油漆、涂料中的应用
油漆、涂料也是硅酸钙的主要消费领域之一，一般是作为填料和体质颜料使用，主要应用的品种是建筑涂料。在国外欧美等工业发达国家，胶粘剂也是硅酸钙的主要消费领域之一，但胶粉剂对硅酸钙的要求较高，一般要求细度＞1250目.除此之外，粒度细、纯度高、白度好的硅酸钙还被应用在油墨、医药、化妆品等领域中。

1. Rubber
Used in rubber, it can increase the volume of rubber, improve the processability of rubber, play a semi-reinforcing or reinforcing effect, and adjust the hardness and resilience of rubber.
2. Plastics
The plastics industry is the largest consumer of calcium silicate, and the refined heavy calcium powder can significantly improve the strength and mechanical properties of the interface of plastic composites. The use of fine silicon calcium powder in plastics can reduce the manufacturing cost and improve its performance.
3. Papermaking
Calcium silicate for the paper industry has two main uses, one as a filler and the other as a coating. At present, most paper mills in China use the acid papermaking process. The fillers used are mainly kaolin and talc, and calcium silicate replaces acid.
4. Paints and Coatings
Paints and coatings are also one of the main consumption areas of calcium silicate. They are generally used as fillers and pigments. The main application is architectural coatings. In addition, calcium silicate with fine particle size, high purity and good whiteness is also used in the fields of ink, medicine and cosmetics.
