HEMC rau Pobzeb Adhesive C1 C2

Hydroxyethyl methylcellulose (HEMC) yog cellulose-raws li polymer siv nyob rau hauv kev tsim kho kev lag luam raws li ib tug additive nyob rau hauv pobzeb nplaum formulations. HEMC yog cov dej-soluble polymer uas muab viscosity, khi, thiab adhesion zog rau cov nplais nplaum. Hauv tsab xov xwm no, peb yuav tham txog cov ntawv thov ntawm HEMC hauv cov ntawv nplaum nplaum, nws cov khoom, cov txiaj ntsig, thiab cov kev pheej hmoo.

HEMC yog dav siv los ua ib qho ntxiv hauv cov nplais nplaum vim nws cov khoom tshwj xeeb, uas pab txhim kho kev ua haujlwm ntawm cov nplaum. Ib qho ntawm cov haujlwm tseem ceeb ntawm HEMC hauv cov nplais nplaum yog muab cov viscosity, uas yog qhov tseem ceeb rau kev sib xyaw kom zoo thiab siv cov nplaum nplaum. HEMC kuj ua raws li kev sib khi, tuav cov nplaum ua ke thiab muab cov khoom adhesion.

Cov nplais nplaum tsim nrog HEMC tau muab faib ua ob pawg: C1 thiab C2. C1 nplaum yog tsim los kho cov vuas luaj ceramic, thiab C2 nplaum yog tsim los kho cov vuas porcelain. Kev siv HEMC hauv cov nplais nplaum nplaum tso cai rau kev txhim kho kev ua haujlwm, txhim kho adhesion, thiab txo qhov nqus dej.

HEMC kuj tseem siv rau hauv cov pobzeb nplaum cov qauv ua cov retarder, uas pab tswj lub sijhawm teem sijhawm ntawm cov nplaum. Qhov no tso cai rau lub sijhawm ua haujlwm ntev dua thiab txhim kho cov khoom adhesion. HEMC tseem muab cov khoom tuav dej, uas tiv thaiv kom qhuav ntxov ntxov ntawm cov nplaum thiab txhawb kev kho kom zoo.

Ib qho txiaj ntsig ntawm kev siv HEMC hauv cov nplais nplaum nplaum yog nws cov kev sib raug zoo nrog lwm cov tshuaj ntxiv thiab cov khoom xyaw. HEMC tuaj yeem siv ua ke nrog lwm cov polymers, xws li polyvinyl acetate (PVA), los txhim kho kev ua haujlwm ntawm cov nplaum. Nws kuj yog sib xws nrog ntau yam fillers, xws li xuab zeb thiab xis mas, uas yog feem ntau siv nyob rau hauv pobzeb nplaum formulations.

HEMC yog ib qho kev nyab xeeb thiab ib puag ncig tus phooj ywg additive, uas yog non-toxic thiab biodegradable. Nws kuj yog heev soluble nyob rau hauv dej, ua rau nws yooj yim mus use thiab koom rau hauv cov pobzeb nplaum formulations. HEMC tseem tiv taus qhov degradation los ntawm UV teeb thiab cov kab mob, ua kom cov nplaum ua haujlwm ntev.

Txawm li cas los xij, muaj feem cuam tshuam nrog kev siv HEMC hauv cov ntawv nplaum nplaum. HEMC tuaj yeem ua rau tawv nqaij thiab qhov muag khaus hauv qee tus neeg, thiab kev raug mob ntev yuav ua rau muaj teeb meem ua pa. Nws yog ib qho tseem ceeb uas yuav tsum tau siv HEMC raws li cov txheej txheem kev nyab xeeb thiab kom tsis txhob cuam tshuam ncaj qha rau ntawm daim tawv nqaij, qhov muag, thiab ua pa.

Hauv kev xaus, Hydroxyethyl methylcellulose (HEMC) yog cov khoom siv dav siv hauv cov nplais nplaum nplaum. Nws muab viscosity, khi, thiab adhesion zog, txhim kho kev ua haujlwm ntawm cov nplaum. HEMC kuj tau sib xws nrog lwm cov tshuaj ntxiv thiab cov khoom xyaw, ua rau nws muaj ntau yam thiab muaj txiaj ntsig zoo ntxiv. Txawm li cas los xij, muaj peev xwm txaus ntshai cuam tshuam nrog kev siv HEMC, thiab nws yog ib qho tseem ceeb uas yuav tsum siv nws raws li cov lus qhia kev nyab xeeb.
