消失模铸造用冷胶的合成及应用

The Synthesis and Application of Cold Glue for Lost Form Casting

消失模铸造用冷胶是用于将消失模白模组装粘接起来的粘结剂。针对消失模铸造用冷胶的性能要求,选择合适的原料及合成工艺,试验合成了三种溶剂型冷胶。对合成的三种冷胶的粘度、固含量、发气量、灼烧残留量等进行了检测和分析,并进行了三种胶的使用性能试验。结果表明,合成的三种冷胶均可满足消失模铸造使用要求,其中工艺三的冷胶性能最优,但发气量较高。

Cold glue for lost form casting was used to bond the white patterns together. The appropriate raw materials and synthesis technology were selected on the basis of the performance requirements of cold glue for the lost foam casting, and three kinds of solvent cold glue were synthesized. The properties of the three kinds of solvent cold glues such as viscosity, solid content, gas release, ignition loss were tested, analyzed, and the serviceability was tested. The results show that the three cold glues can meet the use requirements of EPC. The cold glue manufactured by third process has the best performance, but its gas release is higher.
