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.
