Product description

Gypsum accupies is a very important position in the building material industry. Compared with cement,gypsum has unique and excellent characteristics:
Self curing is fast and the curing time can be adjusted.
Micro expansion after curing, no empty drum and cracking problems existing in cement-based materials.
After curing , a large number of micropore structures are formed inside the material, which has the effect of respiration and sound absorption and sound insulation. This effect of respiration can adjust the humidity of living and working environment, creat a comfortable microclimate, and make gypsum play an increasing important role in interior decoration.
Rich natural gypsum mines, the energy consumption per unit production is 78% lower than that of cement, and can be recycled.
Power plant desulfurization products a large amount of gypsum, also provides a rich source of gypsum.

It is because of the excellent characteristics of gypsum that gypsum material has been more and more widely used.

Hydroxypropyl methyl cellulose is a non-ionic cellulose ether made from natural cotton fiber through a series of chemical processing. They are an odorless, tasteless, non-toxic, off-white powder, which can be dissolved in cold water and organic solvents to form a transparent viscous solution with thickening, bonding, dispersion,emulsification, film formation, suspension and adsorption , gel, surface activity, moisture retention and protective colloid properties.


HPMC is widely used in production and construction
1. Construction industry: As a water-retaining agent and retarder of cement mortar, it has good pumping performance. Use mortar,plaster, putty powder and other building materials as adhesives to improve its applicability and extend its use time.Used for pasting tiles, marbles, plastic decorations, pasting steel bars, and can also reduce the amount of cement. The water retention of HPMC prevents the paste from cracking due to too fast drying after application, and the strength is improved after hardening.
2. Ceramic manufacturing industry: widely used in the bonding of ceramic products.
3. Paint industry: as thickener, dispersant and stabilizer, soluble in water or organic solvents. Used as paint remover.
4. Ink printing: As a thickener, dispersant and stabilizer in the ink industry, it has good compatibility in water or organic solvents.
