Gypsum Board Production Ingredients And Process

Material preparation: Modified starch, retarder, pulp, water reducer and water are quantitatively measured and put into a hydraulic pulper to stir into raw material slurry, and then pumped into the slurry reserve tank for standby; foaming agent and water are put into the foaming agent preparation tank in proportion and stirred evenly, and pumped into the foaming agent reserve tank (with heating device, maintained above 35°C) for standby; coagulant and gypsum powder raw materials are put into the silo for standby through the lifting and conveying equipment; Process: The slurry in the slurry reserve tank is pumped into the mixer by a metering pump, the foaming agent is foamed by a dynamic foaming device and then enters the mixer, the coagulant and gypsum powder are measured by a fully automatic metering belt scale and then enter the mixer, and then all the main and auxiliary materials are mixed into qualified gypsum slurry in the mixer. Note: The addition of all main and auxiliary materials is included in the automatic control system, which is automatically adjusted with the speed of the production line to meet the requirements of large-scale and high speed.
