Hydroxypropylmethylcellulose (HPMC) yog cov khoom muaj ntau yam siv dav hauv kev tsim kho kev lag luam.Nws yog cov organic polymer muab tau los ntawm cellulose thiab yog siv los ua dej-soluble thickener, binder thiab zaj duab xis qub.HPMC plays lub luag haujlwm tseem ceeb hauv kev tsim cov dej-resistant putty hmoov, uas yog siv dav hauv kev tsim kho.
Water-resistant putty hmoov yog ib qho nplaum siv hauv kev tsim kho vaj tsev los sau qhov khoob, tawg thiab qhov hauv cov phab ntsa, cement, qhob, stucco thiab lwm qhov chaw.Nws yog tsuas yog siv los tsim ib tug du nto rau painting, wallpapering los yog tiling.Dej-resistant putty hmoov yog qhov zoo heev rau nws lub peev xwm los tiv thaiv cov dej noo, ua rau nws yuav tsum muaj cov khoom siv rau chav dej, chav ua noj thiab lwm qhov chaw ntub dej.
Muaj ntau qhov zoo rau kev siv HPMC hauv cov dej resistant putty hmoov.
HPMC yog tus neeg saib xyuas dej zoo heev, uas tuaj yeem txhim kho kev ua haujlwm ntawm cov tshuaj tiv thaiv dej uas nquag siv hauv cov hmoov putty.Nws kuj tseem pab tiv thaiv kom tsis txhob ya raws los ntawm kev nkag mus rau putty rau lub sijhawm ntev, ruaj khov.Tsis tas li ntawd, HPMC yog ib zaj duab xis yav dhau los uas tsim muaj kev tiv thaiv kev tiv thaiv ntawm qhov chaw ntawm lub putty, tiv thaiv dej los ntawm kev nkag mus thiab ua rau kev puas tsuaj.
Lwm qhov txiaj ntsig ntawm HPMC nyob rau hauv dej-resistant putty hmoov yog los txhim kho lub zog ntawm lub putty thiab txhim kho nws adhesion rau lub substrate.Cov cuab yeej no ua rau HPMC cov khoom tseem ceeb hauv cov txheej txheem putty, kom ntseeg tau tias cov putty adheres rau saum npoo thiab tsis tawg lossis tawg thaum lub sijhawm.Nrog rau qhov sib ntxiv ntawm HPMC, dej-resistant putty hmoov ua kom ruaj khov, ruaj thiab siv tau yooj yim, ua rau lawv muaj kev xaiv nrov ntawm cov kws tsim kho.
Ntxiv nrog rau nws cov khoom tiv thaiv dej, HPMC kuj tseem muaj txiaj ntsig zoo rau ib puag ncig kev cuam tshuam ntawm dej-resistant putty hmoov.Nws cov xwm txheej biodegradable kom ntseeg tau tias cov putty yog ib puag ncig tus phooj ywg thiab tsis ua mob rau ib puag ncig.HPMC kuj tsis muaj tshuaj lom thiab tsis tsim cov pa phem lossis tsw ntxhiab, ua rau nws muaj kev nyab xeeb siv hauv tsev thiab tsev.
Kev siv hydroxypropyl methylcellulose (HPMC) nyob rau hauv dej-resistant putty hmoov yog ib qho tseem ceeb muaj nyob rau hauv kev tsim kho kev lag luam.Nws cov dej-repellent thiab cov khoom nplaum ua rau nws muaj cov khoom zoo heev rau putties, muab lub sijhawm ntev, ruaj tiav uas tiv taus ya raws thiab ib puag ncig hnav.Ntxiv rau, nws yog biodegradable thiab tsis muaj tshuaj lom, ua rau nws muaj kev nyab xeeb rau kev siv hauv cov chaw pej xeem.Los ntawm kev siv HPMC, peb tuaj yeem tsim cov qauv nrog ntau dua durability, stability thiab sustainability.
