Gypsum board production process

Ingredients:

Preparation:

The modified starch, the retarder, the pulp, the water reducing agent and the water are quantitatively metered, put into a hydraulic pulper and stirred into a raw material slurry, and then pumped into the slurry storage tank for use;

The foaming agent and water are proportionally put into the foaming agent preparation tank and stirred uniformly, and pumped into the foaming agent storage tank (with a heating device and kept above 35 ° C) for use;

The coagulant and gypsum powder raw materials are fed into the silo through the lifting conveying equipment;

Ingredients:

The slurry in the slurry storage tank is pumped into the mixer using a metering pump. The foaming agent is foamed using a dynamic foaming device and then enters the mixer. The coagulant and gypsum powder are metered into the mixer using a fully automatic metering belt, and then all the main The excipients are mixed into a qualified gypsum slurry in a blender.

Description: All the main and auxiliary materials are included in the automatic control system, and are automatically adjusted according to the speed of the production line to meet the requirements of large-scale and high-speed;

Plastics are also called synthetic resins and are broadly classified into two categories; thermosetting resins and thermoplastic resins.

The thermosetting resins include phenolic resin and melamine resin, which are thermally hardened and never become soft again. Thermoplastic resins include PVC, polyethylene (PE), polystyrene (PS) and polypropylene (PP), which can be re-softened by heating
