摘　　要：研究了固化剂加入量对自硬呋喃树脂砂可用时间、脱模时间、发气量、24 h抗拉强度、含水量等性能指标的影响,得出了各参数随固化剂加入量变化的曲线图。综合考虑各参数对型砂性能的影响,实际生产中固化剂适宜加入量为40%~60%。The effects of the varying amounts of hardener on the properties of self hardening furan resin sand,such as working time,stripping time,gas evolution,24 h tensile strength,moisture content,were studied.The curve of each property changing with the addition amount of curing agent was obtained.Considering the overall influence of the addition amount of hardener on the properties of molding sand,the suitable amount of hardener is advised for 40%-60%in the actual production.
