Cellulose Ether White Hpmc Powder For Construction Putty CAS 9004-65-3

 

Introduction:

HPMC was used widely in the construction industry. The yield and consumption of HPMC are increased sharply in recent years. HPMC has different types, cold water fast dissolving type and hot dissolving type. Cold water fast dissolving HPMC can be used in putty powder, mortar, liquid glue etc.. Hot dissolving type HPMC can be used for dry powder products. It can mix with dry powder and use directly like putty powder and mortar. The water retaining property and stability of cold water fast dissolving type is worse than that of hot dissolving type. So the customers should choose different types according to different applications.

 

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.

Application:

HPMC has the effect of thickening, water retaining and construction in putty powder.

1. HPMC can thicken and make the solution uniform. Then avoid sagging.

2. HPMC makes putty powder dry slower and help ash calcium powder react in water.

3. Construction: HPMC has lubrication action, which makes putty powder has a good condition for construction.

HPMC has no any chemical reaction but assistant. HPMC only retains water and help ash calcium powder react well but no any chemical reaction was involved.

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.

Properties:

1. Water retention: The water retention will be enhanced, which is helpful with such problems as cement or gypsum construction material drying too fast and poor hardening or cracking.

2. Adhesivity: It can make mortar attach to base material better sincethe plasticity of mortar is enhanced.

3. Operationality: It can enhance the plasticity of mortar and improve the coating efficiency in construction projects.

 

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. It can load 12MT in one 20GP and 25MT in one 40GP.

FAQ

1. How to choose the viscosity of HPMC?

Generally HPMC with 100000mpa.s is enough for putty powder and for mortar, HPMC with 150000mpa.s will be better.

2. What is the main technical index of HPMC?

Most of the customers pay more attention to Hydroxypropyl content and viscosity. The water retaining property of HPMC with higher Hydroxypropyl content is better. The bigger the viscosity, the better the water retaining. In mortar, HPMC with high viscosity is better.

3. Can we get smaller quantity of HPMC?
Generally our MOQ is 1000kg and we can deliver it by sea, by air or courier like FedEx etc.. We always do it according to the requirements of the customers.
4. Can you accept the customized packaging?
Generally we provide 25kg/carton for our customers. But if you have some special requirements, we can do that if you have a large quantity.
5. What is your payment terms?
We have T/T, LC, DP, Paypal, Moneygram and many other payment terms. For the first cooperation, we prefer T/T in advance or LC at sight.
