HPMC yog dab tsi?

HydroxyPropy cellulose (HPMC) yog hom cellulose ether tau los ntawm ntuj cellulose. Nws yog tsim los ntawm kev siv cellulose cellulose los ntawm kev qhia txog ob pawg methlopropyl thiab methyl pawg mus rau lub cellulose caj qaum. HPMC yog qhov ntau thiab dav siv polymer nrog ntau cov ntawv thov hla ntau kev lag luam vim nws cov teeb tsa ntawm cov khoom.

Ntawm no yog qee cov yam ntxwv tseem ceeb thiab kev siv HPMC:

Cov yam ntxwv tseem ceeb:

1. Dej Solubility:
   • HPMC yog soluble hauv dej txias, thiab nws solubility tuaj yeem hloov kho raws cov qib ntawm cov pab pawg hydroxypropyl thiab methyl pawg.
2. Zaj duab xis-tsim muaj peev xwm:
   • HPMC tuaj yeem tsim cov yeeb yaj kiab ntshiab thiab hloov tau yooj yim thaum qhuav. Cov cuab yeej no yog pab tau tshwj xeeb rau cov ntawv thov xws li txheej ci thiab cov yeeb yaj kiab.
3. Thickening thiab gelling:
   • HPMC pabcuam ua cov neeg sawv cev ua kom zoo thiab ua kom pom tseeb, muab cov xim muaj ntau yam, suav nrog cov xim av, suav nrog cov xim av, cov nplaum, thiab tshuaj pleev ib ce.
4. Cov haujlwm saum npoo:
   • HPMC muaj cov khoom saum npoo av uas pab nws lub peev xwm los ua kom muaj emulsions thiab txhim kho kev sib dhos ntawm cov txheej txheem.
5. Kev ruaj khov thiab sib xyaw:
   • HPMC yog qhov ruaj khov nyob rau hauv ntau hom PH cov kev mob thiab tau tshaj nrog ntau lwm yam khoom xyaw, ua rau nws haum rau kev siv nyob rau ntau hom.
6. Dej khaws cia:
   • HPMC tuaj yeem txhim kho dej khaws cia hauv ntau cov ntawv thov, suav nrog cov khoom siv tsim kho, muab cov haujlwm txuas ntxiv.

Cov ntawv thov ntawm HPMC:

1. Cov Khoom Siv Siv:
   • Siv nyob rau hauv cov khoom siv cov paj ntaub ntawv xws li mortars, renders, thiab cov nplaum nplaum kom txhim kho kev ua haujlwm, kom dej ua ke, thiab cov tshuaj nplaum.
2. Kws Tshuaj:
   • Feem ntau siv nyob rau hauv cov kws ua tshuaj ua haujlwm zoo li lub binder, ua txhaum cai, zaj duab xis-txheej tus neeg sawv cev, thiab txhawb nqa-tso tawm sib npaug.
3. Tshuaj pleev ib ce thiab kev saib xyuas tus kheej:
   • Pom nyob rau hauv cov khoom xws li lotions, cream, tshuaj pleev haus, thiab tshuaj pleev ib ce ua cov neeg sawv cev tuab, tawv ncauj, thiab zaj duab xis, thiab zaj duab xis, thiab zaj duab xis, thiab zaj duab xis, thiab zaj duab xis, thiab zaj duab xis.
4. Xim thiab pleev xim:
   • Siv hauv cov xim pleev xim rau cov dej thiab txheej ci los muab viscosity tswj, txhim kho cov khoom thov, thiab txhim kho zaj duab xis tsim.
5. Kev Lag Luam Khoom Noj:
   • Ua haujlwm ua tuab, stabilizer, thiab emulsifier hauv cov khoom noj khoom haus.
6. Cov nplaum:
   • Siv hauv ntau cov qauv nplaum kom tswj viscosity, txhim kho cov nplaum, thiab txhim kho kev ruaj khov.
7. Polymer dispersions:
   • Muaj nyob rau hauv polymer dispersions rau nws stabilizing cuam tshuam.
8. Ua Liaj Ua Teb:
   • Siv nyob rau hauv agochemical cov qauv tsim los txhim kho kev ua haujlwm ntawm tshuaj tua kab thiab chiv.

Kev xaiv HPMC cov qib nyob ntawm cov yam xws li qhov xav tau, cov dej solubility, thiab cov kev thov rau cov dej. HPMC tau muaj cov npe nrov raws li lwm yam thiab muaj txiaj ntsig zoo polymer hauv ntau kev lag luam, ua rau kev txhim kho ntawm cov khoom ua haujlwm thiab qhov zoo.
