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.
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.
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.
