Cellulose ethers yog cov khoom xyaw tseem ceeb siv hauv kev tsim kho, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov mortars ntub dej rau ntau yam kev siv xws li flooring, ru tsev thiab plastering. Lub hom phiaj tseem ceeb ntawm cellulose ether nyob rau hauv ntub mortar yog los txhim kho nws cov kev ua tau zoo los ntawm kev ua kom nws viscosity. Wet mortar yog ib qho khoom siv uas siv tau rau kev sib txuas thiab kaw cov khoom siv hauv tsev sib txawv. Hauv cov phiaj xwm architectural, kev thov kom raug yog qhov tseem ceeb rau kev ua tiav thiab kev ua haujlwm ntev ntawm cov qauv. Yog li ntawd, kev siv cov cellulose ethers nyob rau hauv ntub mortars yog qhov tseem ceeb los ua kom viscosity kom zoo sib xws thiab kev ua tau zoo.
Ib qho txiaj ntsig tseem ceeb ntawm kev siv cellulose ethers hauv cov mortars ntub yog nce viscosity. Viscosity ntawm ntub mortar hais txog lub peev xwm ntawm qhov sib tov kom ntws smoothly thiab tusyees. Cellulose ether yog qhov zoo rau lub hom phiaj no vim nws tsim cov tshuaj colloidal thaum ntxiv rau dej, txhim kho hydrophilicity thiab adhesion. Yog li ntawd, cov mortar ntub yuav ua rau tawv thiab khov dua, uas tso cai rau kom muaj kev sib raug zoo rau lub tsev.
Cellulose ether yog ib tug zoo meej dej tuav tus neeg sawv cev uas pab txoj kev ua hauj lwm ntawm ntub mortars. Thaum sib tov nrog cellulose ether, ntub mortar kuj muaj cov dej tuav zoo heev, tiv thaiv cov dej molecules los ntawm evaporating rau ntau teev los yog hnub, ncua sij hawm teem sij hawm ntawm mortar. Qhov no txhim kho kev ua haujlwm ntawm qhov sib tov, muab sijhawm rau cov neeg ua haujlwm kom txaus thiab ua tiav cov haujlwm ua ntej cov khoom ntub dej.
Lwm qhov txiaj ntsig tseem ceeb ntawm kev siv cellulose ethers hauv cov khib nyiab ntub yog kev txhim kho cohesion ntawm mortar. Nws paub zoo tias qhov zoo ntawm cov khoom siv hauv tsev mortar muaj feem cuam tshuam rau kev pabcuam lub neej thiab kev ua haujlwm ntev ntawm cov qauv. Cov khib nyiab ntub dej uas muaj cellulose ether tuaj yeem tsis tsuas yog sib txuas sai nrog lwm cov ntaub ntawv hauv tsev, tab sis kuj tseem ruaj khov thiab kav ntev. Yog li ntawd, kev taw qhia ntawm cellulose ether nyob rau hauv ntub mortar tuaj yeem txhim kho nws cov cohesiveness thiab muab txoj hauv kev zoo rau txoj haujlwm ua tiav.
Ntxiv nrog rau cov txiaj ntsig tseem ceeb uas tau hais dhau los, cellulose ethers tuaj yeem txhim kho lub zog ntawm cov khoom ntub dej. Thaum siv hauv mortar ntub, cellulose ethers txhim khu lub peev xwm nplaum ntawm lub mortar, tso cai rau nws ua kom ruaj khov nrog lwm cov ntaub ntawv hauv tsev, suav nrog pob zeb, cib thiab pob zeb. Qhov no ua rau kom cov kav ntev thiab kev ua haujlwm ntev ntawm cov qauv, vim tias cov ntawv cog lus muaj zog pab txo qhov kev pheej hmoo ntawm kev puas tsuaj thiab kev puas tsuaj.
Kev siv cov cellulose ethers nyob rau hauv ntub mortars yog ib qho kev daws teeb meem zoo heev rau ntau qhov teeb meem kev tsim kho cov kws tshaj lij hauv lawv cov dej num niaj hnub. Los ntawm kev ua kom cov viscosity, workability, cohesion thiab daim ntawv cog lus lub zog ntawm ntub mortars, cellulose ethers xyuas kom meej tias cov qauv zaum kawg yog ruaj, ntev-ntev thiab muaj peev xwm tiv taus huab cua hnyav. Yog li ntawd, raws li kev tsim kho niaj hnub no, kev siv cellulose ethers hauv cov khib nyiab ntub yog qhov tseem ceeb rau kev ua tiav ntawm kev tsim kho.
Kev siv cellulose ethers nyob rau hauv ntub mortars yog ib qho tseem ceeb ntawm kev txhim kho qhov sib xws, durability thiab kev ua tau zoo ntawm kev sib tov. Cov khoom zoo heev ntawm cov khib nyiab ntub dej, xws li kev txhim kho viscosity, kev ua haujlwm tau zoo, cohesion thiab daim ntawv cog lus muaj zog, ua rau nws zoo tagnrho cov nplaum rau ntau yam kev siv. Yog li ntawd, cov kws tshaj lij kev tsim kho yuav tsum lees txais cov txheej txheem kev tsim kho niaj hnub no thiab hloov kho kom haum kom ntseeg tau tias lawv siv cov ntaub ntawv zoo tshaj plaws hauv lawv cov haujlwm. Cov tswv tsev thiab cov tub ua lag luam tuaj yeem ua tiav cov txiaj ntsig zoo dua, cov qauv tsim muaj zog thiab ua haujlwm ntev ntev los ntawm kev siv cellulose ethers hauv cov khib nyiab ntub dej.
