The HPMC mainly plays a role in water retention and thickening, able to effectively improve the bond force and sag resistance of slurry.

There are different types of viscometers used to measure the viscosity of a cellulose ether solution. The widely adopted viscometers are: HoppIer falling ball viscometer, Haake rotation Rheometer and Brookfield rotation viscometer. The viscometer commonly used in China is NDJ series.

Cellulose ethers are currently the commonly used polymer admixtures of the cement mortar used in construction. Cellulose ethers can be fully dispersed in water to form a transparent viscous liquid. With a small amount (the mass percentage of less than 1%) added to the cement,

SLEOCHEM, a professional manufacturer of cellulose ether (an essential additive of tile adhesives), will tell you what are the causes of tile falling off and the solutions.

Cellulose ether is a non-ionic semi-synthetic polymer derived from cellulose. Cellulose ethers are of two types water-soluble and solvent-soluble. It performs multiple-functions and is useful in different industries. In chemical industries,

Cellulose ether thickening effect depends on: the degree of polymerization of cellulose ether, solution concentration, shear rate, temperature and other conditions. The gelling properties of the solution are unique to alkyl cellulose and its modified derivatives.

SLEOCHEM Cellulose ether is the main additive in ready-mixed mortar. The types and structural characteristics of cellulose ether are introduced. Hydroxypropyl methylcellulose ether (HPMC) is selected as the additive to systematically study the effects on various properties of mortar.

In addition to the adhesion of mortar and substrates obtained by cement, gypsum, calcium hydroxide and dispersible polymer powders, cellulose ethers also provide adhesion.

Each cellulose ether has the basic structure of cellulose-anhydroglucose structure. In the process of producing cellulose ether, the cellulose fiber is first heated in an alkaline solution, and then treated with an etherifying agent. The fibrous reaction product is purified and ground to form a uniform powder with a certain fineness.
