The Resin Coated Sand For Oil Production
Product description
1. Phenolic resin for coated sand has good fluidity and is easy to
be coated.
2. Low free formaldehyde, reduce environmental pollution and
improve working conditions.
3. High strength, not only can improve the quality of coated sand,
but also can reduce the cost by reducing the addition of phenolic
resin.
4. Low gas escape, which is conducive to casting accuracy.
5. By improving the formula to achieve high temperature strength,
the diffusion capacity of resin coated sand can be improved.
Precautions:
1. The place of use should be well ventilated.
2. It must be kept in a cool and dry place, protected from heat and
exposure, preferably refrigerated.
3. The warranty period of ZP204, ZP205, ZP206 is up to 3 months.
4. Those who are allergic to phenol and formaldehyde should be
protected.
The advantage
1) It has suitable strength that can manufacture both high strength
and low strength coated sand.
2) It has good fluidity that can manufacture complex sand cores.
3) The surface quality of sand core is in high quality that it can
use less coating or without coating.
4) It has good collapsibility that the casting is easy to clean up.
5) The sand core has good hygroscopicity that can be stored in a
long time and conveniently to transport.
6) Resin coated sand can be applied as commodity that offer
convenience for customers.
