HPMC thiab HEMC muaj lub luag haujlwm zoo sib xws hauv cov khoom siv.Nws tuaj yeem siv ua dispersant, dej tuav tus neeg saib xyuas, tus neeg sawv cev thickening thiab binder, thiab lwm yam. Nws yog tsuas yog siv hauv cement mortar thiab molding ntawm gypsum khoom.Nws yog siv rau hauv cov cement mortar kom nws adhesion, workability, txo flocculation, txhim kho viscosity thiab shrinkage, ntxiv rau khaws dej, txo cov dej poob ntawm pob zeb nto, txhim kho lub zog, tiv thaiv cov kab nrib pleb thiab huab cua ntawm cov dej-soluble ntsev, thiab lwm yam. Nws yog dav siv nyob rau hauv cement-based plaster, gypsum plaster, gypsum khoom, masonry mortar, ntawv caulking, caulking agent, pobzeb nplaum, self-leveling pem teb khoom, thiab lwm yam. Stabilizer nyob rau hauv emulsion coatings thiab dej-soluble resin coatings, muab cov zaj duab xis zoo abrasion tsis kam, uniformity thiab adhesion, thiab txhim kho nto nro, stability rau acids thiab bases thiab compatibility nrog hlau pigments.Vim nws zoo viscosity cia ruaj khov, nws yog tshwj xeeb tshaj yog haum raws li ib tug dispersant nyob rau hauv emulsified txheej.Nyob rau hauv ib lo lus, txawm hais tias tus nqi nyob rau hauv lub system yog me me, nws yog heev pab tau thiab dav siv.
Lub gel kub ntawm cellulose ether txiav txim siab nws thermal stability nyob rau hauv daim ntawv thov.gel kub ntawm HPMC feem ntau yog nyob ntawm 60 ° C mus rau 75 ° C, nyob ntawm seb hom, pab pawg neeg cov ntsiab lus, cov txheej txheem ntau lawm ntawm cov tuam txhab sib txawv, thiab lwm yam. Vim yog cov yam ntxwv ntawm HEMC pawg, nws muaj qhov kub thiab txias, feem ntau saum toj no. 80 ° C.Yog li ntawd, nws qhov ruaj khov nyob rau hauv qhov kub thiab txias yog siab dua li ntawm HPMC.Nyob rau hauv kev xyaum, nyob rau hauv lub kub heev kev tsim kho nyob rau hauv lub caij ntuj sov, cov dej tuav ntawm HEMC nyob rau hauv ntub mix mortar nrog tib viscosity thiab dosing muaj ib tug zoo dua HPMC.
Lub ntsiab cellulose ether nyob rau hauv Tuam Tshoj txoj kev tsim kho kev lag luam tseem yog HPMC, vim nws muaj ntau hom thiab tus nqi qis, thiab tuaj yeem xaiv dawb ntawm tus nqi them.Nrog rau kev tsim kho kev lag luam hauv tsev, tshwj xeeb tshaj yog kev tsim kho tshuab thiab kev txhim kho kev tsim kho kom zoo, kev noj ntawm HPMC hauv kev tsim kho yuav nce ntxiv.
