HPMC Cellulose is a non-ionic hydroxypropyl methyl cellulose. It is commonly used as a water retaining agent in cement/mortar applications and is the most commonly used water retaining material. The production process of HPMC cellulose is the alkalization and etherification of cotton fibers to form a polysaccharide ether product. It is not charged by itself and the gel-like material in the charged ions does not participate in any reaction and has stable properties. hpmc cellulose is less expensive than other types of cellulose ethers and is widely used in dry mortar. The role of hydroxypropyl methyl cellulose 1. Thickening effect: HPMC cellulose can make the fresh mortar thicken and have a certain wet viscosity to prevent segregation. 2. Water retention effect: Water retention is also one of the most important properties, which helps to keep the free water in the mortar. It gives more time for the cementing material to hydrate after mortar construction. 3.Outgassing effect: HPMC c
