HPMC siv hauv Tshuaj pleev ib ce

Tshuaj pleev ib ce qib HPMC Hydroxypropyl methylcellulose yog ib tug hluavtaws polymer npaj los ntawm kev hloov tshuaj ntawm natural cellulose li raw khoom. Cellulose ether yog derivative ntawm natural cellulose, cellulose ether ntau lawm thiab hluavtaws polymer yog txawv, nws cov khoom siv yooj yim tshaj plaws yog cellulose, natural polymer compounds.

Khoom nta

1, ntuj raw khoom, 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: soluble nyob rau hauv dej txias, soluble nyob rau hauv ib co organic solvents thiab dej thiab organic solvents sib tov;

3, thickening thiab viscosity: ib qho me me ntawm kev daws teeb meem los tsim cov kua nplaum pob tshab, siab pob tshab, kev ua haujlwm ruaj khov, kev hloov pauv hloov nrog cov viscosity, qis dua viscosity, ntau dua solubility; Txhim kho qhov system txaus stability;

4, ntsev tsis kam: HPMC yog non-ionic polymer, ruaj khov nyob rau hauv hlau ntsev los yog organic electrolyte aqueous tov;

5, kev ua haujlwm saum npoo: cov khoom siv cov tshuaj aqueous muaj cov dej num saum npoo av, emulsification, tiv thaiv colloid thiab txheeb ze stability thiab lwm yam haujlwm thiab cov khoom; Qhov nro saum npoo yog 42 ~ 56Dyn / cm hauv 2% aqueous tov.

6, PH stability: viscosity ntawm aqueous tov yog ruaj khov nyob rau hauv thaj tsam ntawm ph3.0-11.0;

7, dej tuav: HPMC hydrophilic, ntxiv rau slurry, muab tshuaj txhuam, muab tshuaj txhuam cov khoom kom tswj tau cov dej zoo;

8, kub gelation: dej tov ua opaque thaum rhuab mus rau ib tug tej yam kub, kom txog rau thaum tsim ntawm (poly) flocculation xeev, thiaj li hais tias cov tshuaj poob viscosity. Tab sis thaum nws txias nws yuav rov qab mus rau nws qhov kev daws teeb meem qub. Qhov kub ntawm qhov gelation 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, nrog rau ntau yam enzyme kuj, dispersity thiab adhesion yam ntxwv;

Khoom siv

Tshuaj pleev ib ce qib HPMC yog tsuas yog siv nyob rau hauv cov tshuaj niaj hnub, tshuaj ntxuav txhua hnub, tshuaj pleev ib ce thiab lwm yam teb; Xws li tshuaj zawv plaub hau, dej da dej, tshuaj ntxuav lub ntsej muag, tshuaj pleev ib ce, gel, toner, plaub hau txias, cov khoom siv tsis zoo, tshuaj txhuam hniav, cov khoom ua si npuas dej thiab lwm yam.

Lub luag hauj lwm ntawm cov tshuaj pleev ib ce qibHPMC

Nyob rau hauv daim ntawv thov ntawm cov tshuaj pleev ib ce, Tshuaj pleev ib ce qib HPMC mas siv rau cosmetic thickening, foaming, ruaj khov emulsification, dispersion, adhesion, zaj duab xis thiab dej tuav kev ua tau zoo, siab viscosity khoom siv rau thickening, tsawg viscosity khoom mas siv rau ncua kev kawm ntawv dispersion thiab zaj duab xis.
