Cellulose ethers, tshwj xeeb tshaj yog Hydroxypropyl Methylcellulose (HPMC), yog ib qho tseem ceeb muaj nyob rau hauv gypsum plaster vim nws muaj ntau yam txiaj ntsig uas txhim kho cov khoom ua haujlwm thiab kev siv tau.
Txhim kho kev ua haujlwm: HPMC txhim kho kev ua haujlwm tau zoo thiab yooj yim ntawm kev siv gypsum plaster, tso cai rau nws kom kis tau yooj yim dua thiab ua tau zoo ntawm ntau qhov chaw. Nws cov khoom tuav dej tiv thaiv kom qhuav sai, uas yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig zoo ib yam tsis muaj kev cuam tshuam zoo.
Enhanced Adhesion: HPMC txhim kho cov adhesion ntawm gypsum plaster rau cov substrates sib txawv, txhawb kev ruaj khov thiab txo qhov kev pheej hmoo ntawm delamination lossis tawg thaum lub sijhawm. Qhov no ua rau lub sijhawm ntev, ruaj khov plaster tiav.
Superior Crack Resistance: HPMC-kho plaster yog resistant rau cracking, txo qhov tshwm sim ntawm cov kab nrib pleb vim shrinkage los yog txav. Qhov no tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv cov cheeb tsam uas muaj qhov kub thiab txias hloov pauv lossis cov qauv kev hloov pauv.
Lub Sijhawm Qhib Zoo: HPMC txuas ntxiv lub sijhawm qhib ntawm lub plaster, muab sijhawm rau cov neeg siv khoom kom ua tiav lawv cov kev sib tw tiav. Kev txhim kho kev ua haujlwm txhais tau tias txhim kho kev zoo nkauj thiab ua kom zoo nkauj dua zaum kawg.
Tswj Dej Retention: HPMC lub peev xwm tswj tau nqus thiab tso dej kom ntseeg tau tias plaster kho kom zoo, ua rau kom qhuav thiab txo qhov tsis zoo ntawm qhov chaw. Qhov kev tswj hwm dej no pab tsim kom muaj qhov sib luag, tsis muaj qhov kawg.
Kev tuav dej zoo: HPMC hauv plaster formulations muaj cov dej tuav tau zoo, uas yog qhov tseem ceeb thaum lub sij hawm teeb tsa thiab kho theem ntawm daim ntawv thov plaster. Qhov no ua kom lub plaster muaj peev xwm ua rau muaj kev cuam tshuam thiab teeb tsa kom zoo, ua rau muaj zog dua, ruaj khov dua.
Thickening zoo heev: HPMC ua raws li cov thickener muaj txiaj ntsig zoo hauv cov khoom siv gypsum, ua kom cov viscosity ntawm cov khoom, kom ntseeg tau tias nws ua raws li qhov chaw ntsug thiab khaws nws cov duab xav tau.
Anti-Sagging: HPMC zoo tiv thaiv gypsum-raws li cov ntaub ntawv los ntawm sagging los yog collapsing. Lub thickened sib xws ua tiav los ntawm HPMC xyuas kom meej tias cov khoom khaws nws cov duab thiab ua raws li qhov zoo, txawm tias nyob rau ntawm qhov chaw ntsug.
Lub Sijhawm Qhib Ntev: HPMC txuas ntxiv lub sijhawm qhib ntawm cov khoom siv gypsum los ntawm kev ua kom qhuav ntawm cov txheej txheem kom qhuav. Cov qauv zoo li gel tsim los ntawm HPMC khaws cov dej hauv cov khoom siv rau lub sijhawm ntev, yog li ncua sijhawm ua haujlwm.
Cov xwm txheej tsis muaj tshuaj lom thiab sib raug zoo: HPMC qhov tsis muaj tshuaj lom thiab sib raug zoo nrog ntau cov ntaub ntawv ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev coj ua hauv tsev. Nws yog muab los ntawm ntuj cellulose thiab ua rau muaj kev pheej hmoo tsawg heev rau tib neeg kev noj qab haus huv thiab ib puag ncig.
HPMC plays lub luag haujlwm ntau yam thiab tseem ceeb hauv cov ntaub ntawv gypsum, muab cov dej tuav tau zoo, cov nyhuv thickening zoo, txhim kho kev ua haujlwm, tiv thaiv sagging thiab qhib sijhawm ntev dua. Cov khoom no ua rau kom yooj yim tuav, daim ntawv thov zoo dua, txhim kho kev ua tau zoo thiab cov txiaj ntsig zoo kawg hauv ntau daim ntawv thov siv nrog gypsum
