Kieselguhr easily precipitates in the paints without optimization after it is grinded by grinder. Despite this shortcoming, it is widely used in various industries due to its inactive chemical properties and low price. Kieselguhr can improve the brushability of paints and increase the adhesive power. It is broadly used in the wood packing, primer, flat paint and floor paint.
The silicon oxide got from the quartz or tripolit is called amorphous silica. After the quartz or tripolit is mined, the first step is to calcine or cool the materials to make the subsequent crushing and grinding process more easily. At last, it is screened by water.
Silicon oxide can be used as quartz or tripolit and the sandy skeleton sediment of unicellular aquatic plants. The silicon oxide got from the aquatic organic matter, also called diatomaceous earth or diatomite oxidation silicon, plays unique position in the modern paint applications.
The abradability of silicon oxide is quite good because it is difficult to be grinded. Tripolit is softer than quartz and finer in structure.
Kieselguhr features low luster, high filling rate and high oil absorption. It is widely applied in the various sectors and gains many favors from vast customers.
