Abstract: Based on the slaking curve and thermo-gravimetric curve of calcium lime, the rational cold compression molding techniques of calcium carbide were given. According to the properties of raw materials and the requirement to binding agent, ZJ-type composite binding agent, which was mainly mixed with organic and inorganic binding agent, was developed and its performance and binding mechanism were analyzed. In order to meet the need of production hi practice, the proper molding water content, pressure and curing age were determined by experiment and analysis.
