What is hydroxypropyl methylcellulose? Hydroxypropyl methylcellulose is simplified to hydroxypropyl cellulose, appearing as a white or white fibrous or granular powder; the solid is flammable and incompatible with strong oxidants. Hydroxypropyl cellulose is soluble in water and some solvents, such as an appropriate proportion of ethanol/water and propanol/water. The aqueous solution is surface-active. High transparency, stable performance, different gel temperature of different specifications, and solubility changes with the viscosity. The lower the viscosity, the greater the solubility, and the performance of different specifications of HPMC has certain differences. The dissolution of HPMC in water is not affected by pH value. HPMC decreased with methoxy content, gel point, water solubility, and surface activity.
Main uses of hydroxypropyl methylcellulose Hydroxypromethyl cellulose, a cement mortar water retention agent, retarder makes mortar pumping. The plaster, gypsum material, putty powder or other building materials as an adhesive 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 too quickly after application, enhancing the strength after hardening; in the coating industry as a thickening agent, dispersing solvent and an organic solvent; widely used as an adhesive agent in ceramic products; as a thickening agent, dispersing agent and stabilizer in water or organic solvent; in the pharmaceutical industry, hydroxy propylene cellulose is mainly used as coating material; membrane material; controlled polymer material for slow release preparation; stabilizer; suspension; tablet adhesive; adhesive. Dissolution method of hydroxypromethcellulose: All models can be added to the material by dry mixing method or directly added to the room temperature solution, and cold water is preferably dispersed, usually in 10-90 minutes; ordinary models are dissolved with hot water and cooled; if the dissolution is insufficient mixing or the ordinary model is directly added to cold water; if the bubble is dissolved, it can be set for 2-12 hours (the solution consistency determines the specific time) or vacuum or pressurized. An appropriate amount of defoaming agent can also be added. Price of hydroxypropyl methylcellulose The different price of hydroxypropyl methylcellulose purity is also different.
