Drywall Production Equipment In China

Raw materials: Due to the small scale of home manufacturing lines, uncooked gypsum is commonly now not homogenized at once into grinding and calcining. Therefore, the pleasant index of plaster of Paris powder fluctuates greatly, coupled with the gas fluctuation, the product first-rate is very unstable.

From the three-phase evaluation of the plaster of Paris powder in the home gear manufacturing line, the content material of anhydrous gypsum and dihydrous gypsum exceeds the lifelike restriction value, and some plaster of Paris powder anhydrous gypsum content material even reaches extra than 15%, which has a exquisite have an effect on on the water distribution and mixture of gypsum slurry, and without delay impacts the product quality. Face paper is every other uncooked fabric that motives exceptional fluctuations, due to the fact the wooden pulp and waste paper uncooked substances of home paper are no longer handy to acquire in China, so the high-quality warning signs of paper frequently fluctuate greatly, water content, water absorption, strength, moist growth fee and different symptoms are now not uniform and unstable, which is convenient to reason board stripping, grooving, gypsum board power decline and different defects. Other auxiliary substances such as blowing agent and sticking adhesive are regularly wasted and have an effect on the first-class of gypsum board due to the fact there is no high quality gear to measure and manipulate them.
