Hauv kev ua haujlwm, nws yog qhov tseem ceeb heev rau kev cia siab rau cov khoom pov thawj thiab cov khoom siv tau zoo kom ua tiav cov txiaj ntsig xav tau. Ntawm cov ntaub ntawv no yog hydroxypropy kasthylcellulose los yog hpmc. Nws yog lub cellulose ether uas tuaj yeem siv ua cov khoom nplaum hauv tsev xws li vuas, casas, pob zeb ua thiab plaster. Vim nws cov kev ua tau zoo tshaj, HPMC tau dhau los ua cov neeg xaiv tau hauv tsev thiab cov neeg ua haujlwm thoob ntiaj teb.
HPMC yog ntev-saw polymer muab tau los ntawm lub ntuj polymer cellulose. Nws thawj qhov kev siv yog nyob rau hauv kev lag luam kws tshuaj uas cov txheej txheem thiab cov nplaum. Txawm li cas los xij, vim nws cov nplaum nplaum zoo tshaj plaws, HPMC tau dhau los ua cov khoom siv tseem ceeb hauv ntau yam kev tsim kho vaj tsev thiab kev kho vaj tsev.
Kev siv lub ntsiab ntawm HPMC hauv cov khoom tsim kho yog raws li cov kua nplaum wectering. Thaum sib xyaw nrog dej, HPMC tsim ib tug du thiab tuab muab tias adheres zoo rau cov chaw. Adhesives tsim muaj zog thiab ruaj ruaj uas tuaj yeem nkag siab ntau cov neeg kho tshuab, thermal thiab tshuaj lom neeg rau lawv cov kev xaiv zoo tshaj rau cov khoom siv.
Ib qho zoo ntawm HPMC yog nws lub peev xwm los ua raws li dej tuav tus neeg sawv cev. Thaum HPMC ntxiv rau MAAs lossis pob zeb ua ke, nws yuav pab khaws cov dej noo, yog li nce lub zog tag nrho thiab ruaj khov ntawm cov khoom siv. Ib qho ntxiv, HPMC pab txo cov dej uas yuav tsum muaj rau kev sib xyaw, ua rau muaj kev tawg tsawg dua thiab qhov chaw smoother.
Lwm qhov txiaj ntsig ntawm HPMC yog tias nws txhim kho cov ntaub ntawv ua haujlwm, ua rau lawv yooj yim rau kev thov thiab cov duab. HPMC kuj ua raws li cov roj nplua zoo, pab kom txo kev sib txhuam ntawm cov ntaub ntawv, tso cai rau lawv ntws thiab du cov chaw tsis xwm yeem lossis kev nruj.
HPMC kuj muaj feem siv hauv cov nplais nplaum thiab grouts. Nws ua raws li cov nplaum, tuav cov nplais hauv qhov chaw thaum txhim kho adhesion ntawm cov nplais thiab saum npoo. HPMC's nplaum cov khoom tseem pab txhawb cov pobzeb yooj yim yam tsis muaj kev puas tsuaj rau hauv qab, ua rau kev xaiv zoo rau kev teeb tsa ib ntus.
HPMC yog ib puag ncig phooj ywg thiab biodegradable. Nws tsis ua mob rau ib puag ncig lossis ua kom muaj kuab paug. Nws tseem muaj kev nyab xeeb los daws thiab siv thiab tsis ua rau muaj kev pheej hmoo txaus ntshai.
HPMC tau dhau los ua ib feem tseem ceeb ntawm kev tsim kho kev tsim kho. Nws yog siv los ua tus neeg sawv cev ua kom zoo rau cov ntaub ntawv tsim tsev xws li Maas, pob zeb ua kom zoo nkauj thiab cov nplaum thiab cov grouts. Nws cov dej khaws cia, txhim kho kev ua haujlwm thiab kev tsim kho tau zoo ua rau nws cov kev xaiv zoo tshaj plaws rau cov neeg tsim khoom thiab cov lag luam thoob ntiaj teb. Tsis yog HPMC ua tau zoo thiab muaj txiaj ntsig hauv kev siv daim ntawv thov, lawv yog tus phooj ywg ua phooj ywg thiab muaj kev nyab xeeb siv. Raws li qhov tshwm sim, kev siv HPMC hauv kev tsim kho kev tsim kho yuav txuas ntxiv ntxiv, muab cov qauv zoo dua qub, nyab xeeb, muaj kev nyab xeeb ntev.
