Hydroxypropyl methyl cellulose (HPMC), is a cellulose carboxymethyl group substituted products. According to their molecular weight or degree of substitution, can be completely soluble or insoluble polymer, which can be used as a weak acid cation exchange agent, for the separation of neutral or alkaline protein. Carboxymethyl cellulose can form colloidal solution, high viscosity, adhesion, thickening, emulsifying, flow, shaped, water retention, protective colloid, film forming, acid resistance, salt tolerance, suspension and other characteristics, and the physiological harm, so it has been widely used in food, medicine, daily chemical, petroleum, papermaking, textile, construction and other fields in production.
Tile adhesives are cement and/or polymer dispersion-based systems. The rheological additives used for these are mainly cellulose ethers, which provide the right consistency for the application, sag resistance of wall tiles, water retention for the optimum hardening of cement, and the control of open
It depends on the nature of the base course, the parameters of the base material and the use area. This is the principle of choosing tile adhesive On the nature of the base courseWhen it comes to base course, concrete or brick masonry are common. In the selection of ceramic tile adhesive, it is nece
