Cellulose ether hpmc muaj kev ua haujlwm ntawm dej tuav thiab thickening nyob rau hauv cov cement mortar thiab gypsum-raws li mortar, uas tuaj yeem txhim kho qhov adhesion thiab ntsug ntawm cov ntaub ntawv mortar.
Cov yam ntxwv xws li qhov kub thiab txias, qhov kub thiab cua siab tus nqi muaj kev cuam tshuam rau tus nqi ntawm evaporation ntawm noo noo los ntawm cement mortar thiab gypsum raws li cov khoom. Yog li ntawd, muaj qee qhov sib txawv hauv kev ntxiv tib yam ntawm HPMC cov khoom lag luam kom tswj tau cov dej hauv txhua lub caij.
Nyob rau hauv cov pob zeb pouring, cov nyhuv xauv dej tuaj yeem hloov kho los ntawm kev nce thiab txo cov fractional ntws. Cov dej tuav tus nqi ntawm methyl cellulose ether ntawm qhov kub thiab txias yog qhov tseem ceeb ntsuas tus nqi kom paub qhov zoo ntawm methyl cellulose ether.
Cov khoom lag luam zoo HPMC tuaj yeem daws qhov teeb meem ntawm qhov ntsuas kub ntawm qhov ntsuas dej. Nyob rau hauv lub caij kub kub, tshwj xeeb tshaj yog nyob rau hauv kub thiab av noo thiab chromatography kev tsim kho, high-zoo HPMC yog xav tau los txhim kho cov dej tuav ntawm slurry.
Cov khoom zoo HPMC yog qhov sib npaug zoo heev, thiab nws cov methoxyl thiab hydroxypropyl pawg tau muab sib npaug ntawm cov saw molecular ntawm cellulose, uas tuaj yeem txhim kho lub peev xwm ntawm oxygen molecules los ua covalent bonds ntawm hydroxyl thiab ether bonds.
Nws tuaj yeem tswj tau cov evaporation ntawm cov dej los ntawm huab cua kub thiab ua tiav cov dej-xauv siab. High-zoo methylcellulose HPMC tuaj yeem siv rau hauv cov khoom sib xyaw thiab plaster ntawm paris crafts.
Encapsulate tag nrho cov khoom siv los ua ib zaj duab xis moist, thiab cov dej noo nyob rau hauv lub sij hawm yuav raug tso tawm maj mam mus rau lub sij hawm ntev, thiab hnov mob nrog inorganic tshuaj thiab cov ntaub ntawv collagen kom ntseeg tau lub zog thiab tensile zog.
Yog li ntawd, nyob rau hauv lub caij ntuj sov kev tsim kho qhov chaw, thiaj li yuav ua tau cov nyhuv ntawm cov dej txuag, peb yuav tsum ntxiv cov khoom zoo HPMC raws li daim ntawv qhia, txwv tsis pub, nws yuav tshwm sim los ntawm tsis muaj solidification, txo lub zog, tawg, gas nruas. thiab lwm yam khoom tsis zoo. Ua kom qhuav sai heev.
Qhov no kuj ua rau muaj kev nyuaj ntawm kev tsim kho rau cov neeg ua haujlwm. Raws li qhov kub thiab txias, tus nqi ntawm HPMC ntxiv maj mam txo kom ua tiav cov ntsiab lus noo noo ib yam.
