What is the difference between hydroxypropyl methylcellulose and carboxymethylcellulose

Carboxymethyl cellulose CMC, sodium carboxymethyl starch (CMS), the price is relatively cheap (from the performance of the product itself, CMC is a grade lower than Fuying HPMC), carboxymethyl cellulose is used for low-grade putty powder for interior walls Among them, the water retention and stab...

Hydroxypropyl methylcellulose Hpmc water retention effect and principle

In cement mortar and gypsum-based slurry, HPMC mainly plays the role of water retention and thickening. It can effectively improve the binding force and anti-pituitarism of the slurry. Air temperature, air temperature and air pressure velocity affect the volatilization rate of water in cement mor... Read More

Application of Daily Chemical Grade Hydroxypropyl Methyl Cellulose (HPMC) in Daily Chemical Washing

Daily chemical grade hydroxypropyl methylcellulose is a synthetic polymer made from natural cellulose through chemical modification. Cellulose ether is a derivative of natural cellulose. The production of cellulose ether is different from synthetic polymers. Its most basic material is cellulose, ... Read More

Knowledge about cellulose ether

Cellulose ether (CelluloseEther) is made from cellulose through the etherification reaction of one or several etherification agents and dry grinding. According to the different chemical structures of ether substituents, cellulose ethers can be divided into anionic, cationic and nonionic ethers. I... Read More

How to maintain and detect the viscosity of hydroxypropyl methylcellulose?

Apparent viscosity is an important indicator of hydroxypropyl methylcellulose, commonly used measurement methods include rotational viscometry, capillary viscometry and drop viscometry. Hydroxypropyl methylcellulose was previously measured using capillary viscometry using an Ubbelohde viscometer.... Read More

Analysis of different effects of cellulose ether, starch ether and RDP powder on gypsum mortar

Hydroxypropyl Methyl Cellulose (HPMC) 1. It is stable to acid and alkali, and its aqueous solution is very stable in the range of pH=2-12. Caustic soda and lime water do not have much effect on its performance, but alkali can speed up its dissolution rate and slightly increase its viscosity. 2. H... Read More

What are the factors affecting the viscosity of hydroxypropyl methylcellulose?

The application of hydroxypropyl methylcellulose is very extensive, and it has a lot to do with its viscosity, and the viscosity required for different uses of hydroxypropyl methylcellulose is also different, so when we use its products First of all, we should know what its viscosity is, but the ...
