6. Main process:
The basic material for producing such gypsum boards is mainly gypsum powder (calcined gypsum) that the content of CaSO4·1/2H2O is 75% above.
Calcined gypsum, water and various additives are automatically and separately metered and brought into the blending machine by a continuous auto-conveying system before well mixed into pulp and casted onto the gypsum board surface protecting paper which is continuously moving forward. During the progressing process, the pulp is gradually dispersed and well distributed under jarring before brought to the shaping station where the pulp is composed with the back paper of gypsum board and brought through the shaping machine after which the pulp is fully wrapped by an upper and a lower cardboard and pressed into well-regulated flat board which is continuously brought forward as per a stable and strictly controlled speed. After 5 minutes around, the calcined gypsum in the pulp is hydrated again and crystallized into tiny crystal of interpenetrative dihydrate gypsum with a high strength. And then, the wet gypsum board with a certain strength and regular shape is precisely cut into individual boards with set size by an auto-controlled cutting system. The individual boards are orderly arranged, turned over and brought into the dying machine in which the absorbed water in the board is evaporated away in a strict drying atmosphere (The crystal water in the gypsum crystal has no loss). After brought out from the drying machine, the boards are gradually cooled down in the further production process before the front sides of each two boards are folded after turned over again, and the two ends are cut into regularly sized and well-ordered appearance by an end saw. And then, the two ends of the board are packed by paper strips with fixed symbol, and finally the packed boards are sent to the automatic stacking machine and stacked into well-ordered finished products before put into storage.
7. Main technology:
The production line adopts special designed hot air stove heating system, paper supply system, wet board shaping, entering, exiting, drying,
stacking system. Each system controled by central control box .
