Water retention is an important performance of methyl cellulose ether, but also a lot of domestic dry mortar manufacturers concerned about the performance. In the production of building materials, especially dry mortar, cellulose ether plays an irreplaceable role, especially in the production of special mortar (modified mortar), is an indispensable and important part.
Hydroxypropyl methyl cellulose (HPMC) is a natural polymer cellulose material as raw material, made after a series of chemical processing of non-ionic cellulose ether. Under normal circumstances, adding hydroxypropyl methyl cellulose or methyl cellulose to the mortar, the water retention rate can reach more than 85%. The method used in the mortar is to mix the dry powder and add water. Cement with high water retention capacity can be filled with water, the bonding strength is significantly improved, and the tensile and shear strength can be appropriately increased, which greatly improves the work efficiency.
1. Improve lubricity and plasticity to enhance workability and make product construction more convenient and faster.
2.Helping prevent the sag of mortar, mortar and tiles. Extend the cooling time and improve work efficiency.
With a thickening, binding, dispersing, emulsifying, PH value of stability, film, suspension, adsorption, gel, surface activity, maintain a features such as water and protective colloid.
