Product Introduction
Silica powder for jewelry casting and precision casting is a kind of inorganic non-metallic mineral functional powder material, which is made of natural quartz, fused quartz and cristobalite by fine processing such as color separation, magnetic separation, grinding and precision classification. It has good temperature resistance, acid-alkali corrosion resistance, low expansion and high purity, low stress, clean and smooth surface of castings.
Main Features:
1.High purity, good whiteness and uniform particle size distribution.
2. Acid and alkali corrosion resistance, low expansion, high purity and low stress.
3. Good fluidity, high fire resistance, low expansion coefficient and crack resistance.
4.Casting surface is smooth and delicate, which can greatly reduce the polishing cost of users.
5. Low price and can replace expensive zircon powder.
6. Imported casting powder is very expensive, which brings huge cost burden to users. After years of research and innovation, Haosen Mineral has broken the technical blockade of foreign countries. Not only low price, good quality, but also greatly reduced the production cost of users, which makes the domestic casting industry get rid of dependence on foreign casting powder.
Application:
It is used in precision jewelry casting such as gold, platinum,K gold and so on. It is the main raw material in jewelry casting process. It is used in precision stainless steel casting, shoe mold casting, advanced building materials, national defense and other fields.
