What is hydroxypropyl methylcellulose? Hydroxypropyl methylcellulose, also known as Hypromellose, is one of the non-ionic cellulose mixed ethers. Dissoluble in water, insoluble in hot water, DMF, DMSO, hot glycol, and pyridine, and insoluble in absolute ethanol, diethyl ether, and chloroform. The aqueous solution is surface active, dried into a thin film, heated and cooled, and undergoing a reversible transition from sol to gel. HPMC can be divided into the instant type and hot soluble type. For instant products, they are quickly dispersed in cold water and disappear in water. The liquid has no viscosity because HPMC is only dispersed in water without real dissolution. In about 2 minutes, the viscosity of the liquid gradually increases, forming a transparent, sticky colloid. Heat-soluble products formed in cold water can quickly be dispersed and disappear in hot water. When the temperature drops to a certain temperature, the viscosity slowly appears until a transparent viscous colloid is formed. The hot soluble type can only be used in putty powder and mortar. In liquid glue and paint, an agglomeration phenomenon can not be used. Instant type, a wide range of applications, in the putty powder and mortar, as well as liquid glue and paint, can be used. There is no taboo.
Main uses of hydroxypropyl methylcellulose Hydroxypropyl methylcellulose is used as a thickening agent, dispersant, binder, excipient, oil-resistant coating, filler, emulsifier, and stabilizer in the textile industry. It is also widely used in synthetic resin, petrochemical, ceramics, paper, leather, medicine, food and cosmetics, and other industries. 1, construction industry: as cement mortar water retention agent, retarder, mortar with pumping. As an adhesive, the plaster, gypsum material, putty powder, or other building materials improve the daub and extend the operating time. Use as ceramic paste tile, marble, plastic decoration, and paste enhancer still can reduce cement dosage. The water retention performance of HPMC makes the slurry not crack because of dries too fast after daub, enhancing the strength after hardening. 2, ceramic manufacturing industry: widely used as an adhesive in manufacturing ceramic products. 3, coating industry: As a thickening agent, dispersant, and stabilizer, water or organic solvents have good phase solubility. As a depaint agent. 4, ink printing: in the ink industry, as a thickener, dispersant, and stabilizer, water or organic solvents have good phase solubility.
