CMC can be used in ceramic body, glazing pulp, and decoration, Used in ceramic body, it is a good strengthening agent, which can strengthen the mouldability of mud and sand materials, help the shaping of the base and increase the folding strength of the green body. Used in glazing pulp and decoration, it is a binder that plays a role of suspending, uncoagulating, and keeping water.
CMC is macromolecule compound with multichain, and the linear chain will open, spread, interact and form the network collide after the water swelling.
Meanwhile, the macromolecule chain with oxhydryl has hydration with water and twine with each other, and then increase the water phase viscosity.
It has the excellent compatibility in water or in organic solvent, as well as the pigment. It used as thickener, dispersant and stabilizer in coating industry.
Industrial-grade hydroxypropyl methyl cellulose used in mortar is distinguished by viscosity. Generally, the following types are commonly used Low viscosity: 400 is mainly used for self-leveling mortar. Reason: low viscosity, good leveling, high mortar density. Medium and low viscosity: 20000-400000
Hydroxypropyl methyl cellulose ether-HPMC, as an auxiliary additive widely used in the field of building materials, is mainly used for water retention, thickening and improving the workability of the finish product. Water retention rate is often one of the core indicators for selecting high-quality
