Hydroxypropyl methylcellulose, feem ntau hu ua HPMC, yog cov khoom siv dav siv hauv cov khoom noj khoom haus, tshuaj, kev tsim kho, tshuaj pleev ib ce, thiab cov khoom tu tus kheej.Nws yog ntuj cellulose ether uas yog tsim los ntawm cov tshuaj hloov kho ntawm cellulose, ib tug natural polymer muab tau los ntawm cov nroj tsuag.Cov txheej txheem hloov kho muaj kev qhia txog hydroxypropyl thiab methyl pawg rau cov cellulose molecule, uas hloov nws cov khoom thiab ua rau nws muaj ntau yam siv rau ntau yam kev siv.
Muaj ntau hom HPMC muaj nyob rau hauv kev ua lag luam, txhua tus muaj nws tus kheej cov khoom tshwj xeeb uas ua rau nws tsim nyog rau cov ntawv thov tshwj xeeb.Hauv tsab xov xwm no, peb yuav tham txog hom loj ntawm HPMC, lawv cov yam ntxwv thiab kev siv.
1. HPMC E5
HPMC E5 yog ib hom HPMC uas muaj viscosity tsawg thiab yog tus cwj pwm los ntawm nws cov adhesion zoo, dej tuav thiab thickening zog.Nws yog feem ntau siv nyob rau hauv kev tsim kho kev lag luam raws li ib tug additive nyob rau hauv cement-raws li cov khoom los txhim kho lawv workability, dej tuav, thiab kev sib raug zoo zog.Nws kuj tseem siv rau hauv kev tsim cov vuas luaj ceramic, gypsum khoom, thiab plastering compounds.Hauv kev lag luam khoom noj khoom haus, nws yog siv los ua tus neeg sawv cev thickening hauv cov khoom noj siv mis, kua ntses, thiab kua zaub.
2. HPMC E15
HPMC E15 yog hom HPMC uas muaj qhov nruab nrab viscosity thiab yog tus cwj pwm los ntawm nws cov dej khaws cia siab, thickening thiab dispersing zog.Nws yog feem ntau siv los ua tus neeg sawv cev thickening thiab stabilizer hauv kev tsim khoom noj, nrog rau hauv kev lag luam kws tshuaj raws li cov khoom siv los txhim kho cov viscosity thiab sib xws ntawm cov tshuaj.Nws kuj tseem siv rau hauv kev tsim cov tshuaj pleev ib ce thiab cov khoom tu tus kheej los txhim kho lawv cov kev ntxhib los mos thiab ruaj khov.
3. HPMC E50
HPMC E50 yog ib hom HPMC uas muaj viscosity siab thiab yog tus cwj pwm los ntawm nws cov thickening zoo heev, dej tuav thiab ua yeeb yaj kiab.Nws yog feem ntau siv nyob rau hauv zus tau tej cov coatings, xim, thiab adhesives raws li ib tug thickener thiab binder.Nws kuj tseem siv rau hauv kev lag luam khoom noj los txhim kho kev ntxhib los mos thiab ruaj khov ntawm cov khoom xws li cov khoom ci, cheese, thiab cov nqaij ua tiav.
4. HPMC K4M
HPMC K4M yog ib hom HPMC uas muaj viscosity siab thiab yog tus cwj pwm los ntawm nws cov thickening zoo heev thiab cov khoom nplaum.Nws yog feem ntau siv nyob rau hauv kev lag luam kws tshuaj raws li ib tug excipient los txhim kho lub dissolution tus nqi thiab bioavailability ntawm cov tshuaj, raws li zoo raws li hloov kho qhov tso tawm profile ntawm cov tshuaj.Nws kuj tseem siv rau hauv kev lag luam khoom noj los txhim kho kev ntxhib los mos thiab ruaj khov ntawm cov khoom xws li dej haus, khoom noj txom ncauj, thiab cov khoom qab zib khov.
5. HPMC K100M
HPMC K100M yog ib hom HPMC uas muaj viscosity siab heev thiab yog tus cwj pwm los ntawm nws cov thickening zoo heev, zaj duab xis-tsim thiab ruaj khov-tso cov khoom.Nws yog feem ntau siv nyob rau hauv kev lag luam kws tshuaj raws li ib tug excipient los txhim kho cov bioavailability thiab tswj kev tso tawm ntawm cov tshuaj.Nws kuj tseem siv rau hauv kev tsim cov coatings, xim, thiab cov nplaum los txhim kho lawv cov thickening thiab binding zog.
Hauv kev xaus, HPMC yog ntau yam polymer uas muaj ntau yam kev siv hauv ntau yam lag luam.Qhov sib txawv ntawm HPMC muaj nyob rau hauv kev ua lag luam ua rau nws muaj peev xwm xaiv qhov tsim nyog tshaj plaws rau ib daim ntawv thov tshwj xeeb raws li nws cov khoom thiab cov yam ntxwv.Qhov cuam tshuam zoo ntawm HPMC rau ntau yam kev lag luam tau ua rau nws muaj kev xaiv nrov raws li cov khoom ntxiv hauv ntau yam khoom.
