呋喃树脂砂强度影响因素研究

Study to the influential factors of furan resin sand strength

通过对影响自硬呋喃树脂砂强度的研究,对影响树脂砂强度的主要因素进行了总结。认为树脂加入量超过1.7%时,树脂砂强度将降低;固化剂加入量也应根据砂温和对砂型硬化速度的不同要求而不同,一般控制在38%~55%之间为宜;随着季节的不同,必须严格控制好砂温。

Study on the effect of the strength of self hardening furan resin sand,The main factors affectingthe strength of resin sand are summarized,That the amount of resin to add more than1.7%,Resin sand strengthwill be reduced,The curing agent should be according to the different requirements of the sand and sand hardeningspeed and different,General control in38%~55%between the appropriate;with the different seasons,must bestrictly controlled sand temperature.
