400 cps hpmc used in self leveing mortar
Self-leveling mortar is a special dry-mix mortar product with leveling and self-compacting functions. Its self-leveling and self-compacting ability is essential to achieve a smooth and seamless ground layer. A good self-leveling product must first have proper operating performance, and be able to maintain its leveling performance and self-healing ability within the construction time, which requires the mortar to ensure its uniformity and stability during this period of time. Secondly, it must have a certain strength, including the bearing capacity and the binding force to the base surface, which is the basis for the normal application of floor materials. The realization of these properties of self-leveling, special types of cellulose ether products play a vital role. Low-viscosity cellulose ether can play a very good suspension effect, prevent the slurry from settling and bleeding; it can ensure that it will not affect the flow effect of the slurry, which is convenient for construction; it also has a certain water retention, which makes the surface effect after leveling Better, reduce mortar shrinkage and avoid cracks.
