Qhov zoo tshaj plaws thiab kev ruaj ntseg ntawm kev siv tshuab ntawm plastering mortar yog qhov tseem ceeb rau txoj kev loj hlob, thiab cellulose ether, raws li cov tub ntxhais additive ntawm plastering mortar, plays lub luag hauj lwm irreplaceable.Cellulose ethermuaj cov yam ntxwv ntawm cov dej khaws cia siab thiab cov khoom zoo wrapping, thiab tshwj xeeb tshaj yog haum rau kev siv tshuabkev tsim khontawm plastering mortar.
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 tus nqi ntawm cov 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 siv tshuab, peb yuav tsum xaiv cellulose ether nrog siab duatuav dejtus nqi.
Plastering mortar 2h sib xws poob
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%. Qhov kev sim 2h tsis sib xws tau ua nrog viscosities ntawm 50,000, 100,000, 150,000, thiab 200,000. Nws tuaj yeem pom tau tias thaum lub viscosity ntawm cellulose ether nce, 2h qhov sib xws poob tus nqi ntawm mortar yuav maj mam txo. 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 qhibsij hawm
Tom qab lubplastering mortaryog txau rau ntawm phab ntsa, vim 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 lub tom ntej leveling kev tsim kho, yog li nws yog tsim nyog los soj ntsuam lub sij hawm teem ntawm lub mortar. 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 tus nqi ntawm mortar. Qhov ntawd yog hais tias, qhov siab dua qhov viscosity ntawm cellulose ether, qhov ntau dua qhov kev tiv thaiv ntawm mortar thiab ntau dua qhov hnav thiab tsim kua muag 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 lub plastering mortar yog sprayed rau ntawm phab ntsa, yog hais tias tus sag kuj ntawm lubmortartsis zoo, lub mortar yuav sag los yog txawm plam tawm, cuam tshuam rau lub flatness ntawm mortar, uas yuav ua rau muaj teeb meem loj rau tom qab kev tsim kho. 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 cov kua dej muaj kuab heev hauv dej, thiab ntau cov huab cua ruaj khov yuav raug qhia thaum lub sijhawm sib xyaw ntawm cov tshuaj khib. 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 tsim nyog rau kev tsim kho tshuab yuav tsum muaj peev xwm ua tau raws li tus nqi ntawm lub zog xav tau los ntawm kev tsim, thiab yuav tsum xaiv cov cellulose ether uas tsim nyog.
Kev sib koom tes ntawm cov txiv neej-tshuab cov khoom yog qhov tseem ceeb ntawm kev tsim kho tshuab, thiab qhov zoo ntawm mortar yog qhov tseem ceeb tshaj plaws. Tsuas yog los ntawm kev siv cov cellulose ether uas tsim nyog tuaj yeem ua rau cov khoom ntawm cov mortar ua tau raws li qhov xav tau ntawm cov tshuab txau.
