摘要
本试验以磷酸二氢钾和氧化镁制备磷酸镁水泥。研究了几种缓凝剂对磷酸镁水泥凝结时间的影响。研究结果发现,三乙醇胺对磷酸镁水泥具有较好的缓凝效果,但对强度的不利影响较大;硼酸-三乙醇胺复合型缓凝剂可以较好地延长磷酸镁水泥的凝结时间,且对抗压强度的影响很小。
This study used magnesium phosphate cement prepared by using KI-I2PO, and MgO,and researched the effects of some retards on it.The result showed that triethanolamine had the retarding effect on magnesium phosphate cement,but did harm for its strength.Boric acid-tfiethanolamine compound can extend magnesium phosphate cement setting time, and has little effect on its compressive strength.
