Txhua Hnub Qib Hypromellose yog ib qho hluavtaws molecular polymer npaj los ntawm ntuj cellulose los ntawm kev hloov tshuaj lom neeg. Cellulose ether yog derivative ntawm natural cellulose. Tsis zoo li hluavtaws polymers, cellulose ether yog tsim los ntawm cellulose, ib tug natural macromolecule. Vim hais tias ntawm cov qauv tshwj xeeb ntawm ntuj cellulose, cellulose nws tus kheej tsis muaj peev xwm los cuam tshuam nrog etherifying tus neeg sawv cev. Tab sis tom qab kev kho mob nrog cov kab mob o, lub zog hydrogen bonds ntawm thiab nyob rau hauv cov saw hlau molecular tau tawg, thiab cov active hydroxyl pawg tau tso rau hauv reactive alkali cellulose, cellulose ether tau txais los ntawm cov tshuaj tiv thaiv ntawm OH pab pawg neeg los yog pab pawg neeg ntawm etherification tus neeg saib xyuas. 200,000 viscosity hypromellose siv hauv Max yog cov hmoov dawb lossis daj. Nws tuaj yeem yaj hauv dej txias thiab cov organic sib tov ntawm cov kuab tshuaj, tsim cov kua nplaum pob tshab. Cov tshuaj aqueous muaj cov dej num saum npoo av, siab pob tshab thiab muaj zog ruaj khov, thiab nws qhov kev sib cais hauv dej tsis cuam tshuam los ntawm pH. Nyob rau hauv cov tshuaj zawv plaub hau, da dej gel thickening, anti-freezing nyhuv, plaub hau, dej ntawm daim tawv nqaij thiab zoo film-forming. Nrog rau qhov nce ntawm cov khoom siv raw, cellulose (anti-freeze thickener) kuj tuaj yeem siv rau hauv cov tshuaj zawv plaub hau thiab da dej gel tuaj yeem txo cov nqi thiab ua tiav cov txiaj ntsig xav tau.
Cov yam ntxwv thiab qhov zoo ntawm txhua hnub hypromellose HPMC yog: 1) chim siab, ua siab mos siab muag, 2) broad pH stability, uas tuaj yeem lav nyob rau hauv thaj tsam ntawm pH 3-11, 3) txhim kho qhov txias; 4, ua npuas ncauj, ua npuas ncauj stability, txhim kho daim tawv nqaij; 5, zoo txhim kho fluidity ntawm lub system. Txhua hnub Hypromellose HPMC yog siv rau hauv tshuaj zawv plaub hau, ntxuav lub cev, tshuaj ntxuav lub ntsej muag, tshuaj pleev ib ce, tshuaj pleev, gels, toners, plaub hau txias, styling khoom, tshuaj txhuam hniav, xab npum, thiab cov khoom ua si npuas da dej. Lub luag haujlwm ntawm hypromellose HPMC hauv kev siv tshuaj pleev ib ce, nws yog tsuas yog siv rau thickening, foaming, ruaj khov emulsification, dispersion, adhesion, film-forming thiab dej tuav cov tshuaj pleev ib ce, siab viscosity khoom siv rau thickening, tsawg viscosity khoom yog tsuas yog siv rau ncua kev kawm ntawv dispersion. thiab zaj duab xis tsim ntawm hypromellose HPMC. Hydroxypropyl methyl fibers yog tsim rau kev lag luam tshuaj txhua hnub nrog viscosity ntawm 100,000,150,000,200,000, raws li lawv tus kheej cov mis los xaiv cov nyiaj ntxiv rau hauv cov khoom yog feem ntau peb mus rau tsib txhiab qhov ntim tshwj xeeb: 25 kg / hnab
