READ MORE Abstract: The modified cement mortar with a water-cement ratio of 0.45, a lime-sand ratio of 1:2.5, and cellulose ether with different viscosities of 0%, 0.2%, 0.4%, 0.6%, 0.8%, and 1.0% was prepared. By measuring the mechanical properties of cement mortar and observing the microscopic morphology, t
READ MORE Hydroxypropyl methyl cellulose VS methyl cellulose 1Hydroxypropyl methyl cellulose soluble in cold water, hot water dissolved will encounter difficulties. But its gelation temperature in hot water is significantly higher than that of methyl cellulose. The solubility of methyl cellulose in cold water
READ MORE The importance of hydroxypropyl methyl cellulose ether (HPMC) to dry mixed mortar HPMC hydroxypropyl methyl cellulose, non-ionic type, in dry mortar commonly used as water retention agent, is the most commonly used water retention material in mortar. HPMC production process is mainly co
READ MORE How to select hydroxypropyl methyl cellulose HPMC from water retention？ Water retention from hydroxypropyl methyl cellulose is one of the important properties of hydroxypropyl methyl cellulose. Factors such as air temperature, temperature and wind speed can affect the evaporation rate of moisture in ceme
