Kev tsim kho tshuab ntawm plastering mortar tau ua tiav nyob rau xyoo tas los no. Plastering mortar kuj tau tsim los ntawm qhov chaw ib txwm siv nws tus kheej sib xyaw rau tam sim no cov khoom siv qhuav-sib xyaw thiab ntub-sib xyaw mortar. Nws cov kev ua tau zoo dua thiab ruaj khov yog qhov tseem ceeb los txhawb txoj kev loj hlob ntawm cov tshuab plastering, thiab cellulose ether yog siv los ua plastering mortar Cov tub ntxhais additive muaj lub luag haujlwm tsis tuaj yeem hloov. Hauv qhov kev sim no, los ntawm kev kho cov viscosity thiab dej tuav ntawm cellulose ether, thiab los ntawm kev hloov kho hluavtaws, cov teebmeem ntawm kev sim ntsuas xws li dej tuav tus nqi, 2h sib xws poob, qhib lub sij hawm, sag resistance, thiab fluidity ntawm plastering mortar ntawm mechanized tsim. kawm. Thaum kawg, nws tau pom tias cellulose ether muaj cov yam ntxwv ntawm cov dej khaws cia siab thiab cov khoom ntim zoo, thiab tshwj xeeb tshaj yog tsim nyog rau kev tsim kho ntawm cov tshuab plastering mortar, thiab tag nrho cov ntsuas ntawm plastering mortar ua tau raws li lub teb chaws tus qauv.
Dej tuav tus nqi ntawm plastering mortar
Cov dej tuav tus nqi ntawm plastering mortar yog ib qho kev nce ntxiv thaum lub viscosity ntawm cellulose ether yog los ntawm 50,000 mus rau 100,000, thiab nws yog ib qho kev poob qis thaum nws yog los ntawm 100,000 mus rau 200,000, thaum cov dej tuav tus nqi ntawm cellulose ether rau tshuab txau tau mus txog. ntau dua 93%. Qhov siab dua cov dej tuav ntawm lub mortar, qhov tsawg dua qhov mortar yuav los ntshav. Thaum lub sij hawm kev sim tshuaj tsuag nrog lub tshuab mortar spraying, nws tau pom tias thaum cov dej khaws cia ntawm cellulose ether qis dua 92%, lub mortar yog nquag los ntshav tom qab muab tso rau ib lub sij hawm, thiab, thaum pib ntawm cov tshuaj tsuag. , tshwj xeeb tshaj yog yooj yim los thaiv cov yeeb nkab. Yog li ntawd, thaum npaj plastering mortar haum rau kev tsim kho tshuab, peb yuav tsum xaiv cellulose ether nrog cov dej tuav ntau dua.
Plastering mortar 2h poob ntawm qhov sib xws
Raws li qhov yuav tsum tau ua ntawm GB / T25181-2010 "Ready Mixed Mortar", ob-teev sib xws tsis tas yuav tsum tau ua ntawm cov plastering mortar zoo tib yam tsawg dua 30%. Lub viscosity ntawm 50,000, 100,000, 150,000, thiab 200,000 tau siv rau 2h qhov kev sim tsis sib xws. Nws tuaj yeem pom tau tias thaum lub viscosity ntawm cellulose ether nce, 2h sib xws poob tus nqi ntawm mortar yuav maj mam txo, uas kuj qhia tau hais tias lub viscosity ntawm cellulose ether tus nqi siab dua, qhov zoo dua qhov kev ruaj ntseg ntawm cov tshuaj khib thiab qhov zoo dua. anti-delamination kev ua tau zoo ntawm mortar. Txawm li cas los xij, thaum lub sijhawm tshuaj tsuag tiag tiag, nws tau pom tias thaum lub sijhawm tom qab kev kho mob, vim tias cov viscosity ntawm cellulose ether siab dhau lawm, kev sib koom ua ke ntawm mortar thiab trowel yuav ntau dua, uas tsis tsim nyog rau kev tsim kho. Yog li ntawd, nyob rau hauv cov ntaub ntawv ntawm kom ntseeg tau tias lub mortar tsis nyob thiab tsis delaminate, qhov qis dua tus nqi viscosity ntawm cellulose ether, qhov zoo dua.
Plastering mortar qhib sijhawm
Tom qab plastering mortar yog txau rau ntawm phab ntsa, vim yog dej nqus ntawm phab ntsa substrate thiab evaporation ntawm noo noo nyob rau hauv lub mortar nto, lub mortar yuav tsim ib tug tej yam lub zog nyob rau hauv ib tug luv luv lub sij hawm ntawm lub sij hawm, uas yuav cuam tshuam rau theem tom ntej kev tsim kho. . Lub sijhawm clotting tau txheeb xyuas. Tus nqi viscosity ntawm cellulose ether yog nyob rau hauv thaj tsam ntawm 100,000 txog 200,000, lub sij hawm teeb tsa tsis hloov ntau, thiab nws kuj muaj qee qhov kev sib raug zoo nrog cov dej tuav tus nqi, uas yog hais, qhov siab dua cov dej tuav, ntev dua. lub sijhawm teem ntawm lub mortar.
Fluidity ntawm plastering mortar
Kev poob ntawm cov khoom siv tshuaj tsuag muaj ntau yam ua rau lub fluidity ntawm plastering mortar. Raws li qhov sib piv ntawm cov khoom siv dej, qhov siab dua qhov viscosity ntawm cellulose ether, qhov qis dua qhov fluidity ntawm mortar. , uas txhais tau hais tias qhov siab dua qhov viscosity ntawm cellulose ether, qhov ntau dua qhov kev tiv thaiv ntawm mortar thiab ntau dua hnav ntawm cov khoom siv. Yog li ntawd, rau kev tsim kho tshuab ntawm plastering mortar, qis viscosity ntawm cellulose ether yog zoo dua.
Sag resistance ntawm plastering mortar
Tom qab plastering mortar yog txau rau ntawm phab ntsa, yog tias qhov sag resistance ntawm lub mortar tsis zoo, lub mortar yuav sag los yog txawm plam tawm, cuam tshuam rau lub flatness ntawm lub mortar, uas yuav ua rau muaj teeb meem loj rau kev tsim kho tom qab. Yog li ntawd, ib tug zoo mortar yuav tsum muaj zoo heev thixotropy thiab sag kuj. Qhov kev sim pom tias tom qab cov cellulose ether nrog viscosity ntawm 50,000 thiab 100,000 tau txhim tsa vertically, cov vuas ncaj qha swb, thaum lub cellulose ether nrog viscosity ntawm 150,000 thiab 200,000 tsis plam. Lub kaum sab xis tseem vertically erected, thiab tsis muaj slippage yuav tshwm sim.
Lub zog ntawm plastering mortar
Siv 50,000, 100,000, 150,000, 200,000, thiab 250,000 cellulose ethers los npaj plastering mortar qauv rau kev tsim kho tshuab, nws tau pom tias nrog kev nce ntawm cellulose ether viscosity, lub zog tus nqi ntawm plastering mortar qis dua. Qhov no yog vim hais tias cellulose ether tsim ib tug high-viscosity tov nyob rau hauv dej, thiab ib tug loj tus naj npawb ntawm cov huab cua ruaj khov yuav raug qhia thaum lub sij hawm sib tov ntawm mortar. Tom qab cov cement hardens, cov cua npuas no yuav tsim ntau cov voids, yog li txo tus nqi ntawm lub mortar. Yog li ntawd, plastering mortar haum rau kev tsim kho tshuab yuav tsum muaj peev xwm ua tau raws li tus nqi ntawm lub zog uas xav tau los ntawm kev tsim, thiab yuav tsum xaiv cov cellulose ether uas tsim nyog.
