Hydroxypropyl methyl cellulose ether (HPMC) muaj kev ua haujlwm ntawm cov dej tuav thiab thickening hauv cov cement mortar thiab gypsum-raws li mortar, thiab 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, nyob rau hauv txhua lub caij, muaj qee qhov sib txawv hauv kev ntxiv cov khoom qub ntawm hydroxypropyl methylcellulose ether (HPMC) los tswj cov dej kom zoo.
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 hydroxypropyl methyl cellulose ether ntawm qhov kub thiab txias yog qhov tseem ceeb ntsuas tus nqi kom paub qhov zoo ntawm hydroxypropyl methyl cellulose ether.
Cov khoom lag luam zoo hydroxypropyl methylcellulose (HPMC) tuaj yeem daws qhov teeb meem ntawm cov dej kub ceev. 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 hydroxypropyl methylcellulose ether (HPMC) yog xav tau los txhim kho cov dej tuav ntawm cov slurry.
High-zoo hydroxypropyl methylcellulose ether (HPMC) yog qhov zoo sib xws, thiab nws cov methoxyl thiab hydroxypropyl pawg tau sib npaug ntawm cov qauv molecular saw ntawm methylcellulose, uas tuaj yeem txhawb kev tsim cov pa oxygen molecules ntawm hydroxyl thiab ether bonds. Muaj peev xwm ua hauj lwm nrog covalent 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 hydroxypropyl methylcellulose (HPMC) tuaj yeem siv rau hauv cov khoom sib xyaw ntawm cov mortar thiab plaster crafts.
Encapsulate tag nrho cov khoom siv los ua ib zaj duab xis moist, thiab cov dej noo hauv cov txheej txheem yuav raug tso tawm maj mam rau lub sijhawm ntev, thiab hnov mob nrog cov organic teeb meem thiab collagen kom ntseeg tau lub zog sib txuas thiab tensile lub zog.
Yog li ntawd, txhawm rau txuag dej ntawm qhov chaw tsim kho thaum lub caij ntuj sov kub, peb yuav tsum ntxiv cov khoom siv zoo hydroxypropyl methylcellulose (HPMC) raws li daim ntawv qhia, txwv tsis pub, nws yuav yog vim tsis muaj coagulation, txo lub zog, tawg, roj nruas. thiab lwm yam khoom lag luam teeb meem tshwm sim los ntawm kev ziab 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 hydroxypropyl methylcellulose ether (HPMC) maj mam txo kom ua tiav cov dej noo tib yam.
