Sublimedgradehydroxypropyl methyl cellulose yog ib qho polymer hluavtaws uas tau npaj los ntawm kev hloov kho tshuaj ntawm cov cellulose ntuj. Cellulose ether yog ib qho derivative ntawm cov cellulose ntuj, cellulose ether ntau lawm thiab cov polymer hluavtaws sib txawv, nws cov khoom siv yooj yim tshaj plaws yog cellulose, cov tshuaj polymer ntuj. Vim yog qhov tshwj xeeb ntawm cov qauv cellulose ntuj, cov cellulose nws tus kheej tsis muaj peev xwm los cuam tshuam nrog tus neeg sawv cev etherifying, tab sis tom qab ua tiav tus neeg sawv cev o, thiab cov saw hlau hauv cov hydrogen bonds muaj zog ntawm cov saw hlau molecular raug rhuav tshem, cov haujlwm ntawm hydroxyl pawg tso tawm rau hauv fiber cable muaj peev xwm teb rau alkali, tom qab etherification tus neeg sawv cev ib qho OH puag rau hauv cellulose ether LOS YOG puag.
Sublimedgrade tshwj xeeb 200 txhiab viscosity
hydroxypropyl methyl cellulose yog ib hom dawb los yog me ntsis nrog me ntsis daj hmoov, thiab tsis muaj ntxhiab, tsis muaj saj, tsis muaj tshuaj lom. Nws tuaj yeem yaj rau hauv dej txias thiab cov organic sib xyaw ntawm cov kuab tshuaj, tsim cov kua nplaum pob tshab. Cov kua dej muaj kev ua haujlwm ntawm qhov chaw, pob tshab siab, ruaj khov, yaj rau hauv dej tsis cuam tshuam los ntawm PH. Nws muaj cov nyhuv thickening thiab antifreezing hauv tshuaj zawv plaub hau thiab tshuaj da dej gel, thiab muaj dej khaws cia thiab zoo zaj duab xis tsim rau cov plaub hau thiab daim tawv nqaij. Nrog rau kev nce ntawm cov khoom siv raw, cellulose (anti-freeze thickener) tuaj yeem siv rau hauv tshuaj zawv plaub hau thiab tshuaj da dej gel ntawm tus nqi qis dua thiab tseem ua tiav cov txiaj ntsig zoo.
Cov yam ntxwv thiab qhov zoo ntawm Sublimed qib cellulose HPMC:
1. Tsis tshua muaj kev khaus, kub siab thiab kev sib deev;
2 Kev ruaj khov ntawm pH dav dav, lav nyob rau hauv pH ntau ntawm 3-11;
3. Ua kom pom tseeb txog kev xav;
4 nce thiab ruaj khov cov npuas thiab txhim kho daim tawv nqaij
kev xav:
5. Ua kom zoo dua qhov system liquidity.
Sublimedgrade fiber HPMC daim ntawv thov ntau yam:
Siv rau tshuaj zawv plaub hau, tshuaj ntxuav lub cev, tshuaj ntxuav ntsej muag, tshuaj pleev, tshuaj pleev gel, toner, tshuaj pleev plaub hau, cov khoom siv shaping, tshuaj txhuam hniav, tshuaj ntxuav qhov ncauj, dej ua si npuas.
Sublimedgrade cellulose HPMC lub luag haujlwm.
Daim ntawv thov incosmetic, feem ntau yog siv rau kev ua kom cov khoom zoo nkauj tuab, ua npuas dej, ruaj khov
emulsification, dispersion, adhesion, zaj duab xis thiab dej retention kev ua tau zoo dua, cov khoom viscosity siab siv rau thickening, cov khoom viscosity qis feem ntau siv rau kev ncua dispersion thiab zaj duab xis.
Kev siv tshuab sublimed cellulose HPMC:
Hydroxypropyl methyl fiber rau kev lag luam tshuaj txhua hnub viscosity feem ntau yog 100,000, 150,000, 200,000 thiab lwm yam.
