糠醇树脂是我国广大人民公社能生产的耐热、抗蚀、价廉的聚合物，利用它於铸造生产中首 创於我国。本试验中研究了液态与固态的两种树脂，用８字试样测其强度；而树脂作为粘壳用途 是作成膏状且利用型壳余热来固化的。试验证明：由於糠醇与砂的混合物流动性较糠醇树脂的型 砂混合物流动性高，因此吹出性能也较优良。 Furfuryl alcohol resin is a heat-resistant, corrosion-resistant and inexpensive polymer that can be produced by the majority of people’s communes in our country, making use of it in our foundry production. In this study, two kinds of resins, liquid and solid, were studied. The strength of the two resins was measured using a 8-word sample. The use of the resin as a sticky shell was made into a paste and cured with residual heat of the shell. Tests show that: due to the mixture of furfuryl alcohol and sand fluidity than furfuryl alcohol mixture of high sand flow, so the blowing performance is also better.
