    Construction Grade HPMC in Building Materials with good thickening properties

     

    Introduction:

    Construction Grade HPMC has excellent thickening property and it can be used as an anti-dispersing agent. With the development of cellulose production technology and excellent properties of construction grade HPMC, it was used widely in the construction industry. The yield and consumption of HPMC are increased sharply in recent years.

    Characters:
    • HPMC is easily dissolved in cold water and a little hard in hot water. But its gelation temperature in hot water is abviously higher than MC. The dissolving condition in cold water is also much better than MC.
    • The viscosity of HPMC is related to its molecular weight. The bigger the molecular weight, the higher the viscosity. The temperature also influences the viscosity much. The viscosity will be lower with the rise of temperature. But temperature has a smaller influence to the viscosity than MC. So the solution of HPMC is stable in room temperature.
    • The water retaining properties of HPMC depend on the dosage and viscosity. The water retation rate is higher than MC in the same dosage.
    • HPMC is stable to acid and alkali. Its aqueous solution with PH between 2 and 12 is very stable. Caustic Acid and whitewash has a small influence to HPMC properties. But alkali can quicken its speed of dissolving and increase the viscosity slightly. HPMC is also stable to normal salts. But if the concentration of salt solution is high, the viscosity of HPMC solution has a trend of increasing.

    • HPMC can mix water soluble macromolecule compounds to be homogeneous solution with higher viscosity.

    • HPMC has better enzymatic resistance and the possibility of enzyme degradation is much smaller than MC. Meanwhile, the adhesiveness to the mortar is better than MC.

    •  

    Production Process:

    The production process of HPMC is like this, purified cotton → add caustic soda → solvent treatment → etherification → water scrubbing → centrifugalization → dry. In food industry, HPMC can be used as thickening agent, stabilizer, emulgator and gelatinizing agent.

     

    Storage:

    It should be kept away from exposure to the sun, rain and moisture in storage and transportation.

     

    Packaging: 25kg/Bag or according to the requests of the customers.
