HPMC, tseem hu ua cellulose ether, yog ib qho tseem ceeb additive nyob rau hauv zus tau tej cov cement-based hniav finishes thiab renders.Nws ua lub luag haujlwm tseem ceeb hauv kev muab dej khaws cia, ua kom lub ntsej muag du thiab du, thiab tiv thaiv kev tawg.
Cov hniav zoo nkauj no feem ntau yog siv rau cov txheej txheem sab nrauv, muab kev tiv thaiv los ntawm huab cua hnyav.Feem ntau, lawv muaj nyob rau hauv cov xim dawb los yog inorganic xim.Peb lub tuam txhab muaj cov qib HPMC li niaj zaus, nrog rau kev hloov kho HPMC kom haum rau cov neeg siv khoom tshwj xeeb.Peb cov HPMC hloov kho tau dhau los kho qhov chaw, ua rau cov dej tawg sai sai, qhib lub sijhawm qhib, thiab cov khoom tiv thaiv sagging, thiab lwm yam txiaj ntsig.
Nrog rau qhov sib ntxiv ntawm HPMC, cov khoom siv kho kom zoo nkauj tiav thiab ua tiav tau zoo dua qub, ua haujlwm ntev, thiab ua haujlwm tau zoo.Nws yog ib qho kev txhim khu kev qha thiab muaj txiaj ntsig zoo rau kev ua haujlwm siab ntawm cov cement-based coatings.
