Preparation for gypsum board production: modified starch, retarder, pulp, water reducing agent and water are put into hydraulic pulp crusher for mixing to form raw material pulp after quantitative measurement, and then pump into slurry reserve tank for standby; The foaming agent and water are mixed evenly in the foaming agent preparation tank in proportion, and pumped into the foaming agent reserve tank (with heating device, kept above 35 ℃) for standby; The raw materials of coagulant and gypsum powder are transported by lifting equipment into the silo for standby.
Production process of gypsum board: the slurry in the slurry reserve tank is pumped into the mixer by metering pump, and the foaming agent is blown by dynamic foaming device and then into the mixer. The coagulant and gypsum powder are measured by full-automatic measuring belt, and then all main and auxiliary materials are mixed into qualified gypsum slurry in the mixer. Note: all the main and auxiliary materials are included in the automatic control system, which can be adjusted automatically according to the speed of the production line to meet the requirements of large-scale and high speed.
