1. Special baozhu sand product description

Our company is one of the earliest large-scale enterprises specializing in the production of baozhu sand (jewelry sand, electric melting ceramic sand, ceramic sand), with an annual output of 22,000 tons. Reliable product quality, a large number of long-term exports to Germany, Japan, South Korea and other precision casting industry developed countries. It is widely used in various casting methods (investment mold, solid mold, lost mold, etc.); It is specialized in precision casting, coated sand, self-hardening sand for new casting sand, also used for shot peening (aluminum, copper, steel castings). This product is made of high quality aluminum ore raw materials by high temperature calcination, electric melting, high pressure gas spray cutting, cost-effective is much better than zircon sand, chromite sand; In particular, its low expansion, no sintering, no pulverization, no cracking, no sand (eliminate the negative effect of casting quality), good regeneration performance, and improve the yield of casting.

2. The characteristics of Baozhu sand:

(1) The thermal expansion coefficient is small, the performance can be comparable to zircon sand, with its configuration sand, casting will not produce expansion defects

(2) The sand is spherical, with good fluidity and good air permeability

(3) the surface is smooth and the structure is compact, so that the adhesive can be evenly covered

(4) Baozhu sand belongs to neutral material, acid and alkali adhesive can be used

(5) Good recycling performance and high cost performance

(6) compared with chromite sand, zircon sand, its price is only zircon sand, chromite sand 30-50%. At the same time, because the sand is spherical, its surface area is small, so the amount of resin can be reduced by 30-50%, sodium silicate adding domain ≤4%; The casting defects caused by adhesives were reduced and the yield of castings was improved.

(7) High refractoriness, easy to collapse

(8) The mullite phase of baozhu sand is much higher than that of sintered products, and it has good fire resistance

(9) Large thermal conductivity, good stability, no cracking

(10) Wide range of application: suitable for lost mold, coated sand, sodium silicate sand, resin sand, precision casting and copper, aluminum polishing cleaning.
