Do you know how the resin sand production line works?
Why resin sand? How is it different from traditional sand? Do you understand these problems? Machinery equipment foundry company takes you to understand below.
Resin sand production line.
Significance of resin sand production:
(1) minimize the environmental pollution caused by waste sand removal, so that more than 90% of the waste sand can be recycled.
(2) due to the smooth surface of regenerated sand particles, uniform particle size distribution, less micro powder, can save more than 20% of expensive resin.
(3) regenerated sand has good thermal stability, less thermal expansion, stable chemical properties, lower acid consumption, and easy control of resin sand properties, which is conducive to improving casting quality and reducing defects such as veins and mechanical sand adhesion. Characteristics of furan self-hardening resin sand:
1. The mold (core) has high strength and good collapsibility, which can guarantee the dimensional accuracy and surface quality of the casting.
2, good liquidity, can improve the type (core) filling, improve the quality of type (core) and labor productivity, reduce the labor intensity of workers.
3, energy saving, casting (core) only bake, to meet the requirements of pouring.
4, the old sand can be recycled, can further reduce the cost.
