新型磷酸盐铸造粘结剂自硬砂性能研究

Study on Properties of Phosphate Binder No-Bake Sand

本文以新型磷酸盐为铸造型砂粘结剂,研究了混砂工艺,粘结剂加入量,固化剂加入量对型砂性能的影响,考察了该粘结剂自硬砂铸型脱模时间,型砂可使用时间,溃散性,抗吸湿性等。实验结果表明新型磷酸盐粘结剂良好的综合工艺性能,能满足实际使用要求。

She properties of phosphate binder of no bake sand such as sand mixing technique, the amount of binder and hardener, the scrip time and work time, the shakeout property and humidity resistance are studied in the paper. She experiment showed that the phosphate binder has general technique property and can satisfy practical use.
