Hydroxypropyl methyl cellulose (HPMC) Chinese name: hydroxypropyl methylcellulose Chinese alias: HPMC; hypromellose English name: Hydroxy Propyl Methyl Cellulose English Name: HPMC; (2R, 3R, 4S, 5R , 6S) -3,4,5-trimethoxy-2- (methoxymethyl) -6 - [(2R, 3R, 4S, 5R, 6R) -4,5,6-trimethoxy-2- (methoxymethyl) tetrahydropyran-3- yl] oxy-tetrahydropyran; 1 - [[(2R, 3R, 4S, 5R, 6S) -3,4,5-tris (2-hydroxypropoxy) -6 - [(2R, 3R, 4S, 5R, 6R) - 4,5,6-tris (2-hydroxypropoxy) -2- (2-hydroxypropoxymethyl) tetrahydropyran-3-yl] oxy-tetrahydropyran-2-yl] methoxy] propan-2-ol CAS: 9004-65-3 Molecular formula: C56H108O30 MW: 1261.4387 Purpose: thickener; stabilizer; emulsifier; gelling agent; suspending agents mix. Dissolution: 1. All models can be added to the dry mix method in materials; 2. need to be added directly to the aqueous solution at room temperature, preferably cold water dispersible, after joining the generally 10-90 minutes to thicken; 3 Ordinary model first with hot water dispersed by stirring to dissolve in cold water is added and stirred cooling; if caking phenomenon occurs when the parcel 4. dissolve, stir because of insufficient or ordinary models directly into the cold water of the reasons, you should rapid stirring. 5. If bubbles dissolved can be allowed to stand for 2-12 hours (the time is determined by the solution consistency) or vacuum, pressing, etc. removal, may also be added an appropriate amount of a defoaming agent. Construction industry: a cement mortar: improving cement - sand dispersion, greatly improving mortar plasticity and water retention, to prevent cracks have effect, can enhance the strength of cement. 2, tile cement: increase repression tile mortar plasticity, water retention, improve tile glue relay to prevent chalking. Coating 3, asbestos refractory: Ann as suspending agents, fluidity improving agents, but also improve the relay to the substrate gel. 4. Coagulation gypsum slurry: improve water retention and processing, to improve the adhesive strength to the substrate. 5, the joint cement: Add to joint cement plaster board, the improvement in mobility and retention. 6, latex putty: improve putty resin emulsion-based mobility and retention. 7, plaster: as an alternative to natural products paste, can improve retention, improve gum base with relay. 8, Coating: plasticizer as latex paint, coatings to improve operational performance and flowability improving role. 9, spray paint: the prevention of cement-based or latex spraying system had to sink filler material and improve the mobility and the center pattern with good results. 10, cement, gypsum secondary products: as a cement - asbestos-based materials and other hydraulic binders using extrusion molding, to improve the fluidity, a uniform molded article can be obtained. 11, fiber walls: Because DNase antibacterial action, as sand binder walls is effective. 12. Other: You can use as a thin clay sand mortar and plasterers operator action (PC version) bubble retention agent. Chemical industry: 1, vinyl chloride, vinylidene polymerization: As the polymerization suspension stabilizer, dispersant, with vinyl alcohol (PVA) hydroxypropyl cellulose (HPMC) and dried, can control the distribution and grain shape of particles. 2, bonding agents: as wallpaper bonding agent, instead of starch, usually with vinyl latex paint and use. 3. Pesticides: add to pesticides, herbicides, and can improve the adhesion effect of injection time. 4, latex: latex improve bitumen emulsion stabilizers, styrene-butadiene rubber (SBR) latex thickener. 5, the binder: as pencils, crayons forming binder. Kiln: 1. Electronic Materials: As dense ceramic filter, ferrite bauxite porcelain of extrusion molding the binder and use the same 1.2-propanediol. 2, glaze: as ceramics and enamel glaze and cooperate to improve bonding and workability. 3, refractory mortar: Add to firebrick mortar or pouring stove material can improve plasticity and water retention. Other: 1. Fiber: Indian dye paste used as a pigment, forest soil boron dyes, basic dyes, textile dyes, in addition, Bellows processing, and can be used with a thermosetting resin. 2. Paper: the skin surface for carbon rubber and oil processing and other aspects. 3, leather: used as a last-time lubrication or bonding agent. 4, water-based inks: Add in water-based ink, ink, as a thickener, film former. 5, tobacco: reconstituted tobacco as a binder. Yun Chu: NOTICE sun rain and moisture, avoid direct sunlight, sealed in a dry place.
