Resin-coated sand takes its name from the resin covering its surface. This solid novolac phenolic resin film distinguishes it from hot-box sand, which uses liquid...

As early as the 1930s, graphite production and processing began at Liumao in Jixi, Heilongjiang, and Nanshu in Shandong. The beneficiation processes at the time...

The relationships among softening point, minimum viscosity and strength were analyzed, indicating a direction for developing high-softening-point, high-strength phenolic resins. Resin-coated sand shell peeling...

Hot-box release agents can be used in resin-coated sand casting, while cold-box release agents can be used in self-setting furan resin sand casting, making release easier and improving efficiency...

A release agent is an interfacial coating applied between surfaces that readily adhere to each other. It helps surfaces separate easily and remain smooth and clean...

Dibutyl phthalate. Formula: C16H22O4. Properties: a colorless, transparent, oily liquid with an aromatic odor; combustible, insoluble in water and soluble in common organic...

1. Introduction. Types and applications: German chemist Baeyer first synthesized phenolic resin in 1872. In 1907, Belgian-American Baekeland proposed heat curing...
