Cellulose ethers are often used as water-retaining agents in (desulfurized) gypsum mortar. Years of research have shown that,water-retaining agent has a very important influence on the gypsum quality and anti-plastering layer performance of plastering gypsum.

Hydroxyethyl methyl cellulose ether, referred to as HEMC, is a non-ionic cellulose ether obtained from natural polymer material cellulose through a series of chemical reactions. It is an odorless, tasteless, non-toxic white to off-white powder or granule, which can be dissolved in cold or hot water to form a transparent viscous solution, which has the functions of thickening, binding, water retention, dispersion, emulsification and film formation.

Cellulose water-retaining agentAt present, the most widely used in the market is hydroxypropyl methyl cellulose, followed by methyl cellulose, and then carboxymethyl cellulose. The comprehensive performance of hydroxypropyl methyl cellulose is better than that of methyl cellulose, and the water retention of the two is much higher than that of carboxymethyl cellulose, but the thickening effect and bonding effect are worse than that of carboxymethyl cellulose.
