The cellulose ether is a polymer compound. For more than 60 years, these products have played a significant role in a host of applications, from construction products, ceramics, and paints to foods, cosmetics, and pharmaceuticals.
HPMC has low viscosity and is widely used in self-leveling. Self leveling is a very advanced construction technology. As the whole ground is naturally flat, the interference of the construction personnel is very small, compared with the previous manual leveling process, the flatness and construction speed are greatly improved. In self leveling, hydroxypropyl methyl cellulose has excellent water retention during dry mixing. Because self-leveling requires the mixing mortar to automatically level on the ground, the use of water materials is relatively large. Adding hydroxypropyl methyl cellulose can control the water holding capacity of the ground after pouring, and the water release is not obvious, resulting in high strength and shrinkage of the ground after drying, thus greatly reducing cracks. In addition, the addition of hydroxypropyl methyl cellulose also provides viscosity, anti-settling effect, enhances fluidity and pumpability, and improves floor efficiency.
