HPMC thiab HEMC muaj lub luag haujlwm zoo sib xws hauv cov ntaub ntawv siv hauv kev tsim kho. Nws tuaj yeem siv ua cov tshuaj dispersant, tus neeg sawv cev khaws dej, tus neeg sawv cev thickening thiab binder, thiab lwm yam. Nws feem ntau yog siv rau hauv cement mortar thiab molding ntawm cov khoom gypsum. Nws yog siv rau hauv cement mortar kom nce nws cov adhesion, workability, txo flocculation, txhim kho viscosity thiab shrinkage, nrog rau khaws dej, txo cov dej poob ntawm qhov chaw ntawm cov pob zeb, txhim kho lub zog, tiv thaiv cov kab nrib pleb thiab weathering ntawm cov ntsev soluble hauv dej, thiab lwm yam. Nws yog dav siv rau hauv cement-based plaster, gypsum plaster, gypsum khoom, masonry mortar, sheet caulking, caulking agent, vuas nplaum, self-leveling pem teb khoom, thiab lwm yam. Nws tuaj yeem siv ua zaj duab xis-forming agent, thickener, emulsifier thiab stabilizer hauv emulsion coatings thiab dej-soluble resin coatings, muab cov zaj duab xis zoo abrasion tsis kam, uniformity thiab adhesion, thiab txhim kho qhov nro ntawm qhov chaw, stability rau acids thiab bases thiab sib xws nrog cov hlau pigments. Vim nws zoo viscosity cia stability, nws yog tshwj xeeb tshaj yog tsim raws li dispersant hauv emulsified coatings. Hauv ib lo lus, txawm hais tias tus nqi hauv lub kaw lus me me, nws muaj txiaj ntsig zoo thiab siv dav.
Qhov kub ntawm cellulose ether txiav txim siab nws qhov kev ruaj khov thermal hauv daim ntawv thov. qhov kub ntawm HPMC feem ntau yog li ntawm 60 ° C txog 75 ° C, nyob ntawm hom, cov ntsiab lus ntawm pawg, cov txheej txheem tsim khoom sib txawv ntawm cov chaw tsim khoom sib txawv, thiab lwm yam. Vim yog cov yam ntxwv ntawm HEMC pawg, nws muaj qhov kub ntawm gel siab, feem ntau siab dua 80 ° C. Yog li ntawd, nws qhov kev ruaj khov nyob rau hauv qhov kub siab yog siab dua li ntawm HPMC. Hauv kev xyaum, nyob rau hauv qhov chaw tsim kho kub heev hauv lub caij ntuj sov, qhov kev khaws cia dej ntawm HEMC hauv cov av sib xyaw ntub nrog tib lub viscosity thiab dosing muaj qhov zoo dua li HPMC.
Cov cellulose ether tseem ceeb hauv kev lag luam kev tsim kho hauv Suav teb tseem yog HPMC, vim nws muaj ntau hom thiab tus nqi qis dua, thiab tuaj yeem xaiv tau dawb ntawm tus nqi dav dav. Nrog rau kev txhim kho ntawm kev lag luam kev tsim kho hauv tsev, tshwj xeeb tshaj yog kev nce ntawm kev tsim kho tshuab thiab kev txhim kho cov kev cai zoo ntawm kev tsim kho, kev siv HPMC hauv kev tsim kho yuav txuas ntxiv mus ntxiv.
