Cov ntaub ntawv cement-based yog dav siv hauv kev tsim kho kev lag luam.Cov ntaub ntawv no, uas feem ntau suav nrog cov cement, xuab zeb, dej thiab sib sau ua ke, muaj zog elastic thiab compressive zog, ua rau lawv nyiam rau kev tsim kho thiab kev tsim kho vaj tse.Txawm li cas los xij, kev siv cellulose ethers ua cov khoom siv ntxiv rau cov khoom siv cement tuaj yeem txhim kho lawv cov khoom zoo, tshwj xeeb tshaj yog lawv cov kav ntev, ua haujlwm thiab ntws.Cellulose ethers yog hloov cov carbohydrate tebchaw los ntawm cellulose, ib feem tseem ceeb ntawm cov nroj tsuag cell phab ntsa.
Durability
Lub durability ntawm cov ntaub ntawv cement-based yog qhov tseem ceeb hauv kev tsim kho, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav.Vim lawv cov khoom tuav dej, cellulose ethers tuaj yeem txhim kho cov khoom siv tau ntev.Cov khoom sib xyaw ua rau lub cev thiab tshuaj sib txuas nrog dej, pab txo qis dej los ntawm evaporation thiab txhim kho cov txheej txheem kho.Yog li ntawd, cov ntaub ntawv cement-based ua rau muaj kev tiv thaiv ntau dua rau kev tawg lossis shrinkage, uas yog ib qho tseem ceeb rau kev ua kom ruaj khov mus ntev.Tsis tas li ntawd, cellulose ethers tuaj yeem txhim kho qhov khov-thaw tsis kam ntawm cov ntaub ntawv cement-based los ntawm kev tiv thaiv dej los ntawm kev nkag mus rau hauv qhov hws, yog li txo qhov kev pheej hmoo ntawm kev puas tsuaj los ntawm khov-thaw mus.
Kev ua tau zoo
Kev ua haujlwm ntawm cov ntaub ntawv cement-based yog hais txog lawv lub peev xwm los sib xyaw, nchuav, thiab compacted yam tsis muaj kev sib cais lossis los ntshav.Cellulose ether additives tuaj yeem txhim kho cov txheej txheem ntawm cov ntaub ntawv no, ua rau lawv yooj yim los tuav thiab tswj xyuas thaum tsim kho.Lub compound ua raws li cov thickener thiab stabilizer, txhim kho cov cohesion thiab sib xws ntawm cov khoom siv cement.Qhov kev txhim kho hauv kev ua haujlwm no tso cai rau kev tswj hwm ntau dua ntawm cov khoom ntws, kom ntseeg tau tias nws tuaj yeem nchuav rau hauv cov duab uas xav tau thiab daim ntawv tsis poob nws cov qauv kev ntseeg siab.Tsis tas li ntawd, cellulose ethers tuaj yeem txhim kho lub twj tso kua mis ntawm cov khoom siv cement, ua rau lawv yooj yim thauj los ntawm cov kav dej thiab hoses.
ntws
Flowability yog ib qho tseem ceeb rau cov khoom siv cement, tshwj xeeb tshaj yog rau tus kheej-leveling pob zeb, qhov twg qhov sib xws thiab qhov ntws yog qhov tseem ceeb.Cellulose ethers tuaj yeem txhim kho cov dej ntws ntawm cov cement-based cov ntaub ntawv kom ua tiav cov qib siab sib xws, uas muaj txiaj ntsig zoo hauv kev txo qis qhov tsim ntawm cov hnab ris huab cua lossis npuas hauv cov khoom.Lub compound ua raws li kev hloov kho rheology, txhim kho cov yam ntxwv ntws ntawm cov ntaub ntawv cement-based yam tsis cuam tshuam rau lawv cov khoom siv kho tshuab.Yog li ntawd, cov cement-based cov ntaub ntawv uas muaj cellulose ethers tuaj yeem ua tiav qhov kev pab cuam ntau dua thiab ua kom tiav.
nyob rau hauv xaus
Ntxiv cellulose ether rau cov khoom siv cement tuaj yeem pab txhim kho thiab txhim kho lawv cov khoom.Nws txhim kho cov durability, workability thiab flowability ntawm cement-raws li cov ntaub ntawv, ua nws lub additive ntawm kev xaiv rau kev tsim kho tej yaam num.Lub compound khaws cov dej noo, txhim kho cov cement chaw, thiab txo qhov kev pheej hmoo ntawm kev tawg thiab shrinkage.Tsis tas li ntawd, cellulose ethers tuaj yeem txhim kho kev sib koom ua ke thiab sib xws ntawm cov ntaub ntawv cement-based, tso cai rau kev tswj cov khoom ntws zoo dua, ua kom yooj yim rau kev siv hauv kev tsim kho.Yog li ntawd, kev siv cellulose ethers hauv kev tsim cov khoom siv cement tuaj yeem ua rau muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo.
