Application of Hydroxypropyl Methyl Cellulose in Construction Field Ⅰ. Tile adhesive 1. Make the dry mix ingredients easy to mix without any agglomeration, thus saving working time. And make construction faster and more efficient, improve workability, and reduce costs. 2. By extending the cooling time, the tiling efficiency is improved. 3. Provide excellent adhesion effect
Hydroxypropyl methylcellulose is a white, odorless and tasteless powder with different solubility in cold water and hot water. Products with high methoxyl content are insoluble in hot water above 85°C. Products with medium methoxyl content are insoluble in hot water above 65°C. Products with low methoxyl content are insoluble in hot water above 60°C. Ordinary
Generally speaking, the higher the viscosity, the better the water retention effect. However, the higher the viscosity, the higher the molecular weight of MC, and its solubility will be reduced accordingly, which has a negative impact on the strength and construction performance of mortar. The higher the viscosity, the more obvious the thickening effect on
HPMC Chinese name hydroxypropyl methyl cellulose, non-ionic, is often used as a water retention agent in dry-mixed mortar, and is the most commonly used water retention material in mortar. HPMC production process is mainly cotton fiber (domestic) through alkylation, etherification and generated a polysaccharide-based ether products. It is not charged itself and does not react
The main reason for the blistering of Wall putty powder is the problem of the wall. If the wall is pitted, uneven, and has small pits. It must be blistered. And the amount of blistering depends on the shear force of hydroxypropyl methylcellulose. The higher the viscosity of cellulose, the more bubbles, and vice versa.
