- 摘要:
- 为了探讨改性磷酸盐无机粘结剂在铸造生产中的性能优劣,采用改性磷酸盐无机粘结剂配制自硬砂,分别测试自硬砂的抗拉强度、存放稳定性、可使用时间、发气性、溃散性等性能,并与水玻璃、呋喃树脂等传统粘结剂性能进行比较。通过生产实验验证,发现改性磷酸盐无机粘结剂能用于铸铁、铸钢及低熔点合金的铸造,其用于代替水玻璃应用于高温金属铸造,及代替有机树脂应用于有色合金铸造时,完全可克服砂型溃散性差的问题。改性磷酸盐无机粘结剂自硬砂性能优越。In order to adopt the process and the modified phosphate inorganic binder,respectively,test process and the stability of the tensile strength and storage,can use time,gas generating,collapsibility,such as performance,and compared with sodium silicate,furan resins such as traditional adhesive performance comparison,in order to investigate modified phosphate inorganic binder in foundry production performance.The results show that the modified phosphate inorganic binder can be used in casting of cast iron,cast steel and low melting point alloy,and it can be used in high temperature metal casting instead of sodium silicate.Instead of organic resin used in non-ferrous alloy casting,it can completely overcome the problem of sand mold failure.The self-hardening properties of modified phosphate inorganic binder are superior.
