Product Description Hydroxypropylmethylcellulose (HPMC) is a nonionic cellulose alkyl hydroxyalkyl mixed ether obtained from cellulose by alkalization, etherification, neutralization and washing processes. Hydroxypropyl methyl cellulose ether As a nonionic cellulose mixed ether with excellent performance, HPMC has good dispersing, emulsifying, thickening, bonding, water retention and glue retention properties as other cellulose ethers (such as CMC, MC, HEC, MHEC, HEMC, HBMC). It is soluble in water, also soluble in ethanol and acetone below 70%. It can be widely used as thickener and adhesive.HPMC has thickening, dispersing and emulsifying film-forming properties, and is widely used in petrochemicals, building materials, ceramics, textiles, daily-use chemicals, synthetic resins, coatings and electronics and other industrial fields. Molecular structure and synthetic principle of hydroxypropyl methyl cellulose ether We would like to introduce you to the properties and principles of QINGQUAN cellulose ethers Chemical formula of the product HPMC is a partially methyl and partially polyhydroxypropyl ether of cellulose, which is obtained by alkalizing cellulose and then reacting it with two etheric agents, chloromethane and propylene oxide .

In cement and gypsum based, plasters, the moisture retention effect of HPMC will result in high bond strength and hardness of the plaster after curing. High water retention can make the cement fully hydrated, significantly increase the bond strength, but also appropriate to improve the tensile bond strength and shear bond strength of hardened mortar, but also significantly improve the ease of use and lubricity, greatly improve the construction effect, improve work efficiency. When cement mortar is used, it is important to ensure good water retention because of the strong water absorption of bricks and wall surfaces, coupled with the high sand content of the mortar. Otherwise, bricks etc. can easily adsorb the water out of the mortar, making the mortar partially water-loss and the cement difficult to fully hydrate. The bond strength of mortar composed of sand-lime-cement is very low, and after adding cellulose ether, the bond strength increases significantly, and the tensile bond strength and shear bond strength will be relatively high even if there is a significant eccentric load or horizontal load occurs.
