Nyob rau hauv xyoo tas los no, kev siv cellulose ethers hauv cement plasters tau txais koob meej rau nws ntau yam zoo. Cellulose ethers yog cov khoom siv ntau yam uas muab cov dej tuav tau zoo, txhim kho kev ua haujlwm thiab ua haujlwm ntev hauv cov cement renders. Tsab ntawv xov xwm no yog npaj los muab kev saib xyuas qhov tob ntawm kev siv cellulose ethers hauv cement plastering thiab vim li cas nws tuaj yeem ua tau zoo ntxiv rau txhua qhov kev tsim kho.
Cellulose ether yog dej-soluble polymer muab rho tawm los ntawm cellulose fibers. Nws yog feem ntau siv nyob rau hauv kev tsim kho kev lag luam raws li ib tug additive los txhim kho kev ua tau zoo ntawm cement-based cov ntaub ntawv xws li cov cement renders. Muaj ntau ntau hom cellulose ethers, txhua qhov sib txawv ntawm cov viscosity thiab dej-retaining zog.
Ib qho txiaj ntsig tseem ceeb ntawm kev siv cellulose ethers hauv cov cement renders yog lawv lub peev xwm los txhim kho kev ua haujlwm. Cellulose ethers nce qhov sib xws ntawm cov cement renders, ua rau lawv yooj yim dua rau kev thov thiab sib npaug sib npaug ntawm qhov chaw. Qhov no txhais tau tias tsawg dua lub sij hawm thiab kev siv zog yuav tsum tau ua kom tiav, ua kom tiav, ua kom nws yog ib qho kev xaiv nrov ntawm cov kws tsim kho.
Lwm qhov zoo ntawm cellulose ethers yog lawv lub peev xwm los txhim kho cov dej tuav ntawm cov cement renders. Nws tiv thaiv kev sib xyaw kom qhuav sai heev, tso cai rau lub sijhawm ua haujlwm ntev dua. Qhov no yog tshwj xeeb tshaj yog pab tau nyob rau hauv kub, qhuav huab cua, raws li cov sib tov dries sai sai, ua rau nws nyuaj rau thov thiab ua tiav ib tug du tiav.
Tsis tas li ntawd, cellulose ethers tuaj yeem txhim kho qhov ua haujlwm ntawm cov cement plasters los ntawm kev txhim kho lawv cov kab nrib pleb thiab shrinkage kuj. Thaum ntxiv rau qhov sib tov, nws tsim cov yeeb yaj kiab tiv thaiv ib puag ncig cov cement, tiv thaiv dej los ntawm kev nkag mus rau saum npoo thiab ua rau puas tsuaj. Qhov no pab kom tsis txhob raug nqi kho thiab tu, ua rau nws muaj txiaj ntsig zoo rau kev tsim kho cov haujlwm.
Cellulose ethers kuj muaj cov khoom nplaum zoo heev uas ua rau lawv zoo tagnrho rau siv rau sab nrauv cement rendering daim ntaub ntawv. Nws adheres zoo rau ntau qhov chaw xws li pob zeb, cib thiab pob zeb, kom ntseeg tau ntev, ruaj khov.
Ntxiv nrog rau cov txiaj ntsig no, cellulose ether kuj yog cov khoom lag luam zoo ib puag ncig. Nws yog biodegradable thiab tsis muaj teeb meem rau ib puag ncig, ua rau nws muaj kev xaiv ruaj khov rau kev tsim kho.
Kev siv cellulose ethers hauv cement renders muaj ntau yam txiaj ntsig thiab yog qhov tseem ceeb ntxiv rau txhua qhov kev tsim kho. Nws txhim kho kev ua haujlwm, tuav dej thiab kav ntev, ua kom yooj yim rau kev thov, kav ntev thiab ntau tus phooj ywg ib puag ncig. Kev siv cov cellulose ethers hauv cov cement renders zoo li yuav nrov dua li kev lag luam kev tsim kho txuas ntxiv mus nrhiav kev daws teeb meem zoo thiab muaj txiaj ntsig.
