In some ratio, very-high-early-strength MPC can be produced. By using over-fired magnesia ( MgO) and mono-am-monium phosphate ( NH4H2PO4) as main raw material and borax as retarder. 用氧化镁(MgO)和磷酸二氢铵(NH4H2WPO4)为主要原材料,在一定配合比条件下,制备出超早强型磷酸镁水泥(MPC)。
The production practice of the new RW process for anhydrous ammonia production with am-monium phosphate absorbing ammonia shows that all indexes have reached the design requirements. 在RW型磷铵吸氨生产无水氨新工艺的生产实践表明,各项指标均达到设计要求。
