Generally speaking, the higher its viscosity, the better the water retention effect of the gypsum mortar. However, the higher the viscosity, the higher the molecular weight of the cellulose ether and the corresponding decrease in its solubility, which has a negative effect on the strength and construction properties of the mortar. The higher the viscosity, the more obvious the thickening effect on the mortar, but it is not a positive relationship.

Cellulose ether is commonly used in the fields of insulation mortar masterbatch, putty powder, asphalt roads and gypsum products, and have the ability to improve and enhance the characteristics of building materials and enhance the stability of production and construction suitability. The following is an introduction to the considerations caused by cellulose when using putty powder.

One of the biggest differences between dry mix mortar and traditional mortar is the modification of dry mix mortar with a small amount of chemical additives. Adding one additive to dry mortar is called primary modification, and adding two or more additives is secondary modification.

The greater the viscosity of cellulose ether is, the better the water retention property will be.

With the development of dry-mixed mortar industry, high-quality sand resources are increasingly scarce,so it’s very meaningful to find resources that can replace artificial sand and river sand in dry-mixed mortar.

Cellulose ether, also known as rheological modifier, is an additive used to adjust the rheological properties of fresh mortar,

Cellulose ether is a kind of cellulose derivative, could use in various applications based on its unique properties. HPMC hydroxypropyl methylcellulose and MHEC methyl hydroxy ethyl cellulose are most widely used in dry mix mortar industry, paint and coatings, detergent and oil drilling.

Cellulose ether HPMC mainly plays a role of water retention and thickening in cement mortar and gypsum-based slurry, which can effectively improve the adhesion and sag resistance of the slurry.

The cellulose ether is a polymer compound having an ether structure made of cellulose.
