As for the particle size, the finer the particle, the better the water retention. After large particles of cellulose ether are touched with water, the surface will immediately dissolve to form a gel, which wraps the material to prevent the continuous entry of water molecules.

Cellulose ether is widely used in petrochemical, pharmaceutical, paper, cosmetics, food, beverage, building materials, there are thousands of varieties, is a widely used additive, different uses, have different performance requirements for cellulose products.

In the dry mortar, cellulose ether plays the role of retaining water, thickening and improving construction performance. Good water retention performance ensures that the mortar will not be sanded, dusting and strength due to lack of water, cement hydration incompleted, thickening effect makes the structural strength of the wet mortar greatly enhanced.

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.
