The role of HPMC in wet mortar
1.Wet mixed mortar: mixed mortar is a kind of cement, fine aggregate, admixture and water, and according to the properties of various components, according to a certain ratio, after being measured at the mixing station, mixed, transported to the location where the truck is used, and entered into ...Read more -
Quality Identification of Hydroxypropyl Methyl Cellulose
one. The difference between adulterated hydroxypropyl methylcellulose (HPMC) and pure hydroxypropyl methylcellulose (HPMC) 1. Appearance: Pure hydroxypropyl methylcellulose HPMC looks fluffy and has a low bulk density, ranging from 0.3-0.4g/ml; adulterated hydroxypropyl methylcellulose HPMC has ...Read more -
Anti-cracking mortar, bonding mortar, thermal insulation mortar
anti-crack mortar Anti-crack mortar (anti-crack mortar), which is made of anti-crack agent made of polymer emulsion and admixture, cement and sand mixed with water in a certain proportion, can satisfy a certain deformation without cracking, and cooperate with the grid Cloth works better.

Characteristics and Applications of Hydroxyethyl Methyl Cellulose HEMC
The main characteristics of hydroxyethyl methyl cellulose (HEMC) are: 1. Solubility: soluble in water and some organic solvents, HEMC can be dissolved in cold water, its maximum concentration is only determined by viscosity, solubility varies with viscosity, the lower the viscosity, the greater t...Read more -
Tile Adhesive Construction
There are two kinds of materials commonly used for laying tiles: one is tile adhesive, and the other is the auxiliary paste material tile adhesive, which can also be called tile back glue. The tile adhesive itself is an emulsion-like auxiliary material, so how do we use the tile adhesive correctl...Read more -
How to use tile adhesive correctly
Clean the back of the tile first. If the stains, floating layer and residual release powder on the back of the tiles are not cleaned up, it is easy to gather and fail to form a film after the adhesive is applied. Special reminder, the cleaned tiles can only be painted with adhesive after they are...Read more -
Tile glue, tile adhesive, tile back glue, silly and unclear

What is the difference between HPMC and MC
MC is methyl cellulose, which is obtained by treating refined cotton with alkali, using methyl chloride as an etherifying agent, and making cellulose ether through a series of reactions. Generally, the degree of substitution is 1.6~2.0, and the solubility is also different with different degrees ...Read more -
Factors Affecting the Viscosity Production of HPMC
1. Viscosity Control High-viscosity hydroxypropyl methylcellulose cannot produce very high cellulose only by vacuuming and replacing with nitrogen. However, if a trace oxygen measuring instrument can be installed in the kettle, the production of viscosity can be controlled artificially. 2. Use of...Read more -
