Henan Tianhe; hydroxypropyl methyl cellulose; hydroxyethyl methyl cellulose

Chinese name: English name of hydroxypropyl methylcellulose: Hydroxy Propyl Methyl Cellulose English Name: HPMC main purposes 1. Construction: As cement mortar insurance agent, retarder having a pumping mortar. In the plaster slurry, gypsum material, putty or other building materials as a binder to improve spreadability and extend the operating time. Used as a stick tile, marble, plastic decoration, paste enhancers, can also reduce the amount of cement. HPMC water retention will not dry too fast to make a slurry and cracks in the painting, reinforcing the strength after hardening. 2. ceramics industry: the manufacture of ceramic products are widely used as adhesives. 3. Paint industry: in the paint industry as thickeners, dispersants and stabilizers in water or organic solvents have good compatibility. As a paint stripper. 4. Printing ink: the ink industry as thickeners, dispersants and stabilizers in water or an organic solvent having a good compatibility. 5. plastic: for forming release agents, softeners, lubricants. 6. PVC: PVC production dispersant, the Department of the main additive prepared by suspension polymerization of PVC. 7. Other: This product is also widely used in leather, paper products, fresh fruits and vegetables and textiles. 8. pharmaceutical industry: the coating material; membranes; sustained-release rate controlling polymer material preparation; stabilizer; suspending agent; tablet binder; thickening agent dissolution methods 1. All models can be added using a dry blend method to the material; 2. need to be added directly to the aqueous solution at room temperature, preferably cold water-dispersible, generally after adding 10-90 minutes to thicken; 3. general model with hot water after the first mixing and dispersing, stirring cold water After cooling to dissolve; as caking behavior can occur when the parcel 4. dissolved because of insufficient or ordinary stirring type directly into the cold water of reason, and you should quickly stirred. 5. If bubbles dissolved can be allowed to stand for 12 hours (the time determined by the consistency of a solution) or vacuum, pressure and other methods to remove, may also be added an appropriate amount of a defoaming agent.
