3. Kev lag luam kev tsim kho:
Pobzeb Adhesive:
Hauv kev ua haujlwm, HPMC gel ntxiv rau cov nplais nplaum kom txhim kho lawv cov haujlwm, dej cia thiab ua kom tsev neeg. Nws ntseeg tau ib txoj kev sib txuas lus zoo thiab muaj zog nruab nrab ntawm cov nplais thiab substrate.
Cov Khoom Noj xis:
HPMC gel yog siv nyob rau hauv cov tshuaj xis xws li mortars thiab groutts los txhim kho cov khoom siv hauv tsev, kev ua haujlwm thiab tag nrho cov khoom.
Kev Ntsuas Tus Kheej Cov Lus Cog Tseg:
Lub zog rheological ntawm HPMC gel ua rau siv nyob rau hauv tus kheej-levacting compounds, kom muaj kev hnav khaub ncaws zoo nkauj thiab du hauv cov ntawv thov cov ntaub ntawv flooring.
4. Cov tshuaj pleev ib ce thiab kev lag luam saib xyuas tus kheej:
Cov Khoom Tu Plaub Plaub:
HPMC gel ntxiv rau cov khoom tu plaub hau xws li cov tshuaj pleev plaub hau thiab cov styling los muab viscosity thiab txhim kho kev ntxhibture ntawm cov khoom.
Cov mis tawv tu:
Hauv cov khoom saib xyuas cov tawv nqaij, HPMC gel yog siv los ua tus neeg sawv cev tuab los txhim kho kev ruaj khov thiab xav tias yog cov cream, pleev tshuaj pleev thiab lom.
Cov khoom tiv thaiv hnub:
Vim nws cov dej solubility, hpmc gel feem ntau siv nyob rau hauv kev tsim cov khoom ntawm cov tshuaj pleev thaiv hnub tiv thaiv cov tshuaj pleev thaiv duab kom txhim kho lawv cov dej tsis kam thiab tag nrho kev ua tau zoo.
5. Kho Khoom Kho Mob:
Cov khoom lag luam uas mob siab:
HPMC gel tuaj yeem koom rau hauv cov qhov txhab hnav thiab ntaub qhwv los muab ib puag ncig ntub rau kev ua kom zoo. Nws biocompatibility thiab tsis-toxicity ua nws haum rau kev siv tshuaj kho mob.
Hniav Khoom:
Hauv kev kho hniav, HPMC cov gels yog siv nyob rau hauv cov qauv ntawm cov ntaub ntawv kho hniav ntxiv los pab txhawb cov khoom viscosity thiab teeb sijhawm.
6. Kev Ua Si:
Tshuaj tua kab mob:
HPMC gel yog siv rau hauv cov khoom siv tshuaj tua kab kom txhim kho cov nplaum ntawm cov khoom xyaw thiab txhim kho kev ua tau zoo ntawm cov tshuaj tua kab.
Noob txheej:
Raws li cov noob txheej khoom siv, HPMC gel tuaj yeem txhim kho kev hnav khaub ncaws ntawm cov noob txheej thiab muab kev tiv thaiv ib puag ncig kev ntxhov siab ib puag ncig.
HPMC gel yog cov ntaub ntawv ntau ntau cov ntaub ntawv nrog cov kev siv muaj ntau yam hauv cov tshuaj, kev tsim kho, cov tshuaj pleev, thiab ua liaj ua teb, thiab kev ua liaj ua teb. Nws cov khoom tshwj xeeb, xws li biocompatibility, cov dej solubility, tswj kav thiab rhelology tswj, pab rau nws cov ntawv thov dav hauv ntau yam kev lag luam. Raws li kev tshawb nrhiav thiab kev txhim kho txuas ntxiv, cov kev siv yuav ntawm HPMC cov kua muag yog qhov yuav nthuav dav, ua rau lawv muaj ntau yam kev ua haujlwm tseem ceeb thiab ntau yam nyob hauv ntau daim teb.
