2.Technical Specifications

 

 

C6H7O2 OH x OCH3 y OCH2CHOHCH3 zn

 

 

3. Product Application

 

    In building materials as cement slurry water retention agent, retarder enable mortar with pumping. In the plastering gypsum material, putty powder, or other materials as adhesive,improve spreadability and prolong operation time. Used as a paste ceramic tile, marble, decorative plastic, paste enhancer, also can reduce the dosage of cement. HPMC water retention properties make slurry in paint will do not dry too fast and cracking, enhance the strength after hardening. In addition, in other petrochemical, paint, building materials, paint remover, agricultural chemicals, ink, textile printing and dyeing, ceramics, paper, cosmetics and other products production as thickener, stabilizer, emulsifier, excipients, water-retaining agent, film forming agent.

 

 

4. Physical and Chemical Performance

 

 

1›. The appearance: white or white powder, odorless and tasteless.

2›.  Pacticle size: **0 order by the rate of more than *8.5%; *0 mesh through rate in **0%.

3›. The carbonization temperture: ******0°c.

4›. The appearant density: ***0.*0g/(usually 0.5g/). Specific gravity 1.***1.*1.

5›. Temperture: ******0°c.

6›. Spontaneous combustion temperature of about **0°.

7›. The surface tension of aqueous solution of ****6dyn/cm:*0%.

8›.  HPMC with methoxyl content decreases, the gel point elevation, dissolved in water decline, surface activity also decreased.

9›. The solution: soluble in water and organic solvents, such as an appropriate proportion of ethanol/water, isopropanol/water, two chlorine ethane and Aqueous solution with surfactant, high transparency, stable performance. Products of different specifications in different gel temperatures, this is HPMC thermal gelation properties. The solubility increases with the viscosity and viscosity change, the lower the solubility, higher, different specifications of the HPMC properties have some differences. HPMC solubility in water is not affected by PH value influence
