(HPMC) Dab tsi yog qhov sib txawv nrog lossis tsis muaj?

Nws zoo nkaus li koj hais txogHydroxyPropyyl methylcellulose (HPMC), dav dav siv polymer nyob rau ntau yam kev lag luam suav nrog cov kws muaj kev lag luam suav nrog cov khoom lag luam, kev tsim kho, khoom noj khoom haus, thiab tshuaj pleev ib ce. Qhov sib txawv ntawm HPMC nrog thiab tsis muaj tsab ntawv tus ntawv 'yuav yog tus "qib kev kawm sib txawv, cov khoom lag luam, lossis cov khoom lag luam tshwj xeeb.

HydroxyPropyyl methylulose (HPMC) yog ib nrab hluavtaws, inert, Stotastic Polymer muab tau los ntawm cellulose. Nws feem ntau yog tsim los ntawm kev siv tshuaj lom neeg ntawm cellulose, uas cuam tshuam nrog kev kho cellulose nrog alkali thiab propylene oxide los qhia hydroxypropyl thiab methyl pawg.

Nov yog qee cov ntsiab lus tseem ceeb txog HPMC:

Cov qauv tshuaj lom neeg: HPMC muaj cov saw ntev ntawm cov roj ham nrog hydroxypropyl txuas rau qee cov pawg ntawm hydroxyl (-oh). Qhov sib piv ntawm cov kev hloov no tuaj yeem sib txawv, ua rau cov qib sib txawv ntawm HPMC nrog cov khoom sib txawv.

Cov Khoom Siv Lub Cev: HPMC yog dej-soluble thiab cov ntawv pob tshab, cov ntsiab lus dav hlau thaum yaj hauv dej. Nws Viscosity tuaj yeem tswj los ntawm kev kho cov tsis xws li kev hnyav molecular, cov qib hloov chaw, thiab siab.

Cov Ntawv Thov:

Kws Tshuaj: HPMC yog feem ntau siv nyob rau hauv cov kws tshuaj muaj nyob rau hauv cov tuab, binder, zaj duab xis yav tas los hauv cov ntsiav tshuaj, tsiav tshuaj, thiab cov txuj ci zoo tshaj plaws.
Kev Tsim Kho: Hauv cov ntaub ntawv kev tsim kho xws li Mortars, cov khoom siv khib nyiab, thiab cov nplais nplaum, thiab cov dej ua haujlwm, dej khaws cia, thiab cov nplaum.
Khoom Noj: HPMC yog siv hauv cov khoom lag luam khoom noj raws li cov tuab tuab, stabilizer, thiab emulsifier. Nws feem ntau pom nyob rau hauv cov khoom noj mis nyuj, cov kua ntxwv, thiab cov khoom qab zib.
Cov tshuaj pleev ib ce: HPMC muaj nyob rau hauv cov tshuaj pleev ib ce thiab cov khoom tu tus kheej xws li cream, pleev tshuaj, thiab tshuaj zawv plaub hau kom txhim kho kev ntxhib los mos, thiab zaj duab xis-ua yeeb yam.

Cov txiaj ntsig:

HPMC imparts zoo heev cov dej tsis tau zoo, uas yog qhov tseem ceeb rau kev siv xws li cov dej khov kho uas yuav tsum muaj rau kev kho kom zoo.
Nws txhim kho adhesion thiab cov haujlwm ua haujlwm nyob rau hauv cov ntaub ntawv tsim kho, ua rau muaj kev ua tau zoo thiab kav ntev.
Hauv cov chaw kuaj tshuaj, HPMC pab tswj cov tshuaj tso tawm thiab txhim kho kev rho tawm cov khoom siv hluav taws xob.
HPMC yog suav tias muaj kev nyab xeeb rau kev noj thiab tau lees txais hauv cov khoom noj thiab khoom noj kom zoo nkauj.
Cov qib kawm thiab cov lus qhia tshwj xeeb: HPMC muaj nyob rau hauv ntau qib thiab cov kev qhia tshwj xeeb ua rau cov ntawv thov tshwj xeeb. Cov no suav nrog qhov sib txawv hauv viscosity, qhov loj me, qib hloov mus, thiab lwm yam tsis muaj kev lag luam sib txawv thiab cov qauv.

Kev tswj hwm cov xwm txheej: HPMC feem ntau tau pom zoo li kev nyab xeeb (gras) los ntawm kev tswj hwm kev cai xws li Asmeskas Cov Nyiaj Noj thiab Tshuaj (FDA) thaum siv raws li kev ua haujlwm zoo.

HPMC yog cov polymer ntau yam nrog cov ntawv thov sib txawv thoob plaws kev lag luam. Nws cov cuab yeej tuaj yeem ua kom haum kom tau raws li cov cai tau ua, ua rau nws muaj txiaj ntsig zoo hauv ntau hom thiab cov khoom lag luam. Yog tias koj muaj cov ncauj lus qhia ntxiv txog HPMC nrog lossis tsis muaj tsab ntawv ', thov muab cov ntsiab lus ntxiv rau cov lus piav qhia ntxiv.
