As the main admixture in construction dry-mix mortar products, hydroxypropyl methyl cellulose plays a key role in the performance and cost of dry-mix mortars. Currently, the majority of cellulose ether products are used in construction materials worldwide. An important property of cellulose ethers is their water retention in construction materials. Without the addition of cellulose
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
Cellulose ether is a synthetic polymer made of natural cellulose as raw material by chemical modification. Cellulose ether is a derivative of natural cellulose, cellulose ether production and synthetic polymers are different. Its basic material is cellulose, a natural polymer compound. Due to the particularity of natural cellulose structure, cellulose itself has no ability to
