Cov dej txias instant hydroxypropyl methylcellulose (HPMC) English lub npe: Hydroxypropyl methyl cellulose (HPMC) Hom npe: instant thickener, ruaj khov thickener, emulsion stabilizer, dispersion thickener, antifreeze thickener, Instant cellulose.
Cov khoom tseem ceeb thiab cov qauv tshuaj: non-ionic cellulose ether ua los ntawm ntuj polymer cellulose.
Khoom taw qhia: Hydroxypropyl methylcellulose (HPMC) yog ib qho uas tsis yog-ionic polymer, uas tsis yog-ionic cellulose ether ua los ntawm ntuj polymer khoom cellulose.Cov khoom yog ib qho tsis muaj ntxhiab, tsis qab, tsis muaj tshuaj lom nws tus kheej xim hmoov, uas tuaj yeem yaj hauv dej txias los ua cov kua nplaum nplaum nrog cov thickening, bonding, dispersing, emulsifying, film-forming, suspending, adsorbing, gelling, and deg. nquag, noo noo tuav thiab tiv thaiv colloid zog.
Cov tshuaj txhua hnub qib instant hydroxypropyl methylcellulose HPMC yog siv rau hauv cov tshuaj textile, tshuaj ntxuav txhua hnub, tshuaj pleev ib ce thiab lwm yam;xws li tshuaj zawv plaub hau, ntxuav lub cev, tshuaj ntxuav lub ntsej muag, tshuaj pleev ib ce, cream, gel, toner, kho tawv nqaij plaub hau, cov khoom siv styling, tshuaj txhuam hniav, qaub ncaug, cov khoom ua si npuas dej, thiab lwm yam.
Cov yam ntxwv ntawm cov tshuaj niaj hnub qib instant hydroxypropyl methylcellulose HPMC:
1. Cov khoom siv raw, tsis tshua muaj kev khaus, kev ua haujlwm me me, kev nyab xeeb thiab kev tiv thaiv ib puag ncig;
2. Dej solubility thiab thickening khoom: nws yuav yaj nyob rau hauv dej txias, yaj nyob rau hauv ib co organic solvents thiab sib tov ntawm dej thiab organic solvents;
3. Thickening thiab viscosity-nce: qhov me me ntawm kev sib cais yuav tsim cov kua nplaum nplaum, siab transparency, kev ua haujlwm ruaj khov, solubility hloov nrog viscosity, qis dua qhov viscosity, ntau dua solubility;zoo txhim kho qhov ntws stability ntawm qhov system;
4. Ntsev tsis kam: HPMC yog cov tsis-ionic polymer, kuj ruaj khov nyob rau hauv aqueous daws ntawm hlau ntsev los yog organic electrolytes;
5. Kev ua haujlwm saum npoo: cov kua dej aqueous ntawm cov khoom muaj qhov ua haujlwm saum npoo, thiab muaj cov haujlwm thiab cov khoom ntawm emulsification, tiv thaiv colloid thiab txheeb ze stability;qhov nro saum npoo yog: 2% aqueous tov yog 42 ~ 56dyn / cm;
6. PH stability: lub viscosity ntawm aqueous tov yog ruaj khov nyob rau hauv qhov ntau ntawm PH3.0-11.0;
7. Cov nyhuv dej khaws cia: cov cuab yeej hydrophilic ntawm HPMC tuaj yeem muab ntxiv rau cov khoom slurry, muab tshuaj txhuam thiab pasty kom tswj tau cov dej zoo;
8. Thermal gelation: Thaum lub aqueous tov yog rhuab mus rau ib tug tej yam kub, nws yuav opaque mus txog rau thaum nws tsim ib (poly) flocculation xeev, yog li ntawd cov tshuaj poob nws viscosity.Tab sis tom qab txias, nws yuav tig mus rau hauv cov tshuaj qub qub dua.Qhov kub ntawm qhov tshwm sim gel tshwm sim nyob ntawm seb hom khoom, qhov concentration ntawm cov tshuaj thiab cov cua kub npaum li cas;
9. Lwm yam ntxwv: zoo heev zaj duab xis-tsim zog, raws li zoo raws li ntau yam enzyme kuj, dispersibility thiab cohesiveness;
10. Lub sijhawm viscosity pib ntawm cov tshuaj txhua hnub qib hydroxypropyl methylcellulose hauv cov kais dej ntawm qhov kub thiab txias yog 3 feeb, thiab lub sijhawm pib ntawm cov dej ntshiab yuav qeeb qeeb, txog 30 feeb, kom muaj sijhawm ua haujlwm txaus, yooj yim tswj viscosity , yooj yim rau kev thov.
