Product Description
Characteristics of Baozhu sand
The thermal expansion coefficient is small, and its performance is comparable to that of zircon sand. When it is used to configure molding sand, the casting will not produce expansion defects. The sand particles are spherical, with good fluidity and good air permeability, smooth surface, and dense structure, so that the adhesive can be evenly covered. Baozhu sand is a neutral material, and both acid and alkali adhesives can be used. It has good recycling performance and high cost performance. Compared with chromite sand and zircon sand, its price is only 30-50% of zircon sand and chromite sand. At the same time, because the sand particles are spherical and have a small surface area, the amount of resin added can be reduced by 30-50%, and the addition range of water glass is ≤4%; and the casting defects caused by the adhesive are reduced, and the yield rate of castings is improved.
Product advantages
The mullite phase of Baozhu sand is much higher than that of sintered products, and it has good refractory
The thermal conductivity is large, the stability is good, and it does not crack
Wide application range: suitable for lost foam, coated sand, water glass sand, resin sand, precision casting and polishing and cleaning of copper and aluminum parts.
Our advantages
The company is an enterprise that supplies jewel sand (jewel sand, fused ceramsite, ceramsite sand). The product quality is reliable. It is widely used in various casting methods (investment mold, solid mold, lost foam, etc.); it is a new type of raw sand for professional precision casting, coated sand, self-hardening sand, and is also used for shot peening (aluminum, copper, steel castings). This product is made of high-quality aluminum ore raw materials through high-temperature calcination, electric melting, and high-pressure gas spray cutting. The cost performance is much better than zircon sand and chromite sand; especially its low expansion, no sintering, no pulverization, no cracking, no sand adhesion (eliminating the negative impact of casting quality), good regeneration performance, and improved casting yield rate.
