Daim ntawv thov thiab tshuaj ntau npaum li cas ntawm HPMC nyob rau hauv tus kheej-levelive adhesive

Kev siv tus kheej txoj kev nplaum yog cov nplaum muaj txiaj ntsig siv rau qib thiab kev sib tham hauv kev lag luam ntau yam. Nws cov khoom tshwj xeeb ua rau nws zoo tagnrho rau cov ntawv thov uas yuav tsum tau ua du, xws li flooring, pleev xim thiab phab ntsa nruab.

Ib qho ntawm cov khoom xyaw tseem ceeb uas ua rau nce tus kheej cov nplaum ua kom muaj txiaj ntsig yog hydroxypropyl methylulose (HPMC). HPMC yog qhov ua kom muaj txiaj ntsig ntawm cellulose thiab yog siv dav hauv cov txheej txheej, cov khoom siv tsev, cov nplaum thiab lwm thaj teb.

Lub luag haujlwm tseem ceeb ntawm HPMC nyob rau hauv tus kheej-theem Adhesives yog los tswj lub viscosity thiab sib xws ntawm cov nplaum. Cov cuab yeej Viscoelastic ntawm HPMC tso cai cov nplaum kom ntws khov kho thiab tusyees, ua kom muaj kev sib luag thiab tiaj tiaj.

HPMC kuj txhim kho cov khoom sib txuas ntawm tus kheej cov nplaum nplaum, ua rau nws muaj kev daws teeb meem zoo tagnrho rau ntau hom substrates. Qhov no yog vim HPMC lub peev xwm tshwj xeeb los ua cov nyiaj sib txuam uas muaj zog nrog cov sib txawv, suav nrog cov pob zeb sib txawv, ntoo thiab hlau.

Tus nqi ntawm HPMC siv nyob rau hauv tus kheej-theem nplaum yog nyob ntawm ntau yam ntawm cov substrate, suav nrog hom ntawv nplaum sib xws thiab cov txheej txheem kev cai tshwj xeeb. Feem ntau hais lus, cov tshuaj pom zoo ntau ntawm HPMC yog 0.1% rau 0.5% los ntawm qhov hnyav ntawm cov qauv nplaum.

Thaum ntxiv HPMC mus rau tus kheej txoj kev ua kom zoo nkauj, nws yuav tsum tau muab sib xyaw nrog lwm cov khoom xyaw ntawm cov nplaum. Qhov no ua kom pom tseeb txawm tias kev faib tawm HPMC, ua rau muaj kev sib xws thiab cov nplaum sib txawv.

HPMC ua si lub luag haujlwm tseem ceeb hauv kev tsim cov qauv ntawm tus kheej cov nplaum. Nws cov khoom siv Viscoelastic rau kev ua tiav du, tiaj tus thawj thaj chaw thaum tseem txhim kho cov khoom sib txuas ntawm cov nplaum. Qhov muaj cov tshuaj kho thiab daim ntawv thov ntawm HPMC tseem ceeb heev rau kom ntseeg tau cov kev ua tau zoo ntawm kev ua kom zoo ntawm tus kheej.
