本文介绍碳素醇基涂料在冷硬树脂砂铸铁件上应用的配方、配制工艺及使用效果。
This paper describes the technological process and the result of the application of carbon ethanol-base coating on self-hardening resin sand mold.
实践证明：采用适当工艺附加少量硅酸乙酯，可减少树脂加入量、降低冷硬树脂砂成本。
The experiments prove that after being modified treatment, the addition of cold-hardening resin is cut down, so that the cost of cold-hardening resin sand can be decreased.
