Hangzhou Yingtian Biological Technology Co., Ltd.

Hydroxypropyl methyl cellulose (HPMC), is as natural cellulose as raw material, under certain conditions after alkalization and etherification reaction and the.

Hydroxypropyl methyl cellulose is mainly used for dry mixed mortar and construction putty powder industry. In all the dry mixed mortar shall be mixed with hydroxypropyl methyl cellulose ether and its contribution is mortar increased the water holding capacity, improve liquidity and construction, improve the early strength of cement mortar and avoid cracking. In addition, the product is used in the plaster, paint and other products, are maintaining a high water retention.

Physical and chemical properties

1, appearance: the product is white or slightly yellow, powder, no coarse particles, no impurities. The general fineness is 0.2mm square hole sieve.

2, dry weight loss rate (mainly water): about 5%.

3, the sulfate ash content (ash): less than 5%.

4, viscosity: low viscosity general 100-4000, in the middle of 100000 or so, high viscosity about 200000. Different viscosity, different in use. The sticky putty powder is mainly used for high viscosity, mainly used for dry mixed mortar.

5, pH value: 5-9, was neutral, or slightly acid, alkali.

6, the light transmittance of more than or equal to 80%.

7, gel temperature: 60 degrees celsius.

8, water: 87%.

Main use:

1 construction industry: as cement mortar water retaining agent, retarder to make the mortar pump. In the mortar, gypsum material, putty powder or other materials as adhesive, improve and extend the operational time of painting. For the use of ceramic tile, marble, plastic decoration, paste, and also can reduce the amount of cement. HPMC water retention of the smear after the slurry will not dry too fast and cracked, enhanced strength after hardening.

2 ceramic manufacturing: widely used as binder in the manufacture of ceramic products.

3 coating industry: in the paint industry as a thickening agent, dispersing agent and stabilizer, in water or organic solvents have good compatibility. As paint remover.

4 ink printing: in the ink industry as a thickening agent, dispersing agent and stabilizer, in water or organic solvents have good compatibility.

5: plastic forming release agent, softening agent, lubricant etc..

6 polyvinyl chloride: in the production of polyvinyl chloride as a dispersant, the main auxiliary agent for the preparation of PVC by suspension polymerization.

7 other: This product is also widely used in leather, paper products industry, fruit and vegetable preservation and textile industry, etc..

8. The pharmaceutical industry: coating material; membrane material; sustained release preparation to control the speed of the polymer material; stabilizer; help suspension; tablet binder; adhesive
