Self-leveling mortar tuaj yeem tso siab rau nws tus kheej qhov hnyav los tsim lub tiaj tus, du thiab muaj zog lub hauv paus ntawm lub substrate rau nteg lossis khi lwm yam ntaub ntawv.Nyob rau tib lub sijhawm, nws tuaj yeem nqa cov khoom loj thiab siv tau zoo.Yog li ntawd, lub siab fluidity yog ib qho tseem ceeb heev ntawm tus kheej-leveling mortar Ntxiv rau, nws yuav tsum muaj qee yam dej tuav thiab kev sib raug zoo, tsis muaj dej sib cais tshwm sim, thiab muaj cov yam ntxwv ntawm kev rwb thaiv tsev kub thiab kub tsis tshua muaj siab.
Feem ntau, tus kheej-leveling mortar yuav tsum muaj fluidity zoo.Cellulose ether yog ib qho tseem ceeb ntawm cov khoom sib xyaw ua ke.Txawm hais tias tus nqi ntxiv yog tsawg heev, nws tuaj yeem txhim kho kev ua haujlwm ntawm mortar.Nws tuaj yeem txhim kho qhov sib xws, kev ua haujlwm thiab kev sib koom ua ke ntawm mortar.kev ua haujlwm thiab kev tuav dej.Nws plays lub luag hauj lwm tseem ceeb heev nyob rau hauv lub teb ntawm npaj-mixed mortar.
Cellulose ether muaj ib qho tseem ceeb ntawm kev tuav dej, sib xws thiab kev tsim kho ntawm tus kheej-leveling mortar.Tshwj xeeb tshaj yog raws li tus kheej-leveling mortar, fluidity yog ib qho ntawm cov cim tseem ceeb rau kev ntsuas tus kheej-leveling kev ua tau zoo.Nyob rau hauv qhov kev pom zoo ntawm kev ua kom ntseeg tau qhov qub muaj pes tsawg leeg ntawm mortar, lub fluidity ntawm mortar tuaj yeem hloov kho los ntawm kev hloov cov cellulose ether.Txawm li cas los xij, yog tias qhov ntau npaum li cas siab dhau lawm, qhov fluidity ntawm mortar yuav raug txo, yog li qhov ntau npaum ntawm cellulose ether yuav tsum tau tswj nyob rau hauv qhov tsim nyog ntau.
Cov dej tuav ntawm mortar yog qhov ntsuas tseem ceeb los ntsuas qhov ruaj khov ntawm cov khoom siv sab hauv ntawm cov cement mortar tshiab.Txhawm rau kom ua tiav cov dej ntws tawm ntawm cov khoom siv gel, tus nqi tsim nyog ntawm cellulose ether tuaj yeem tswj tau cov dej noo hauv mortar rau lub sijhawm ntev.Feem ntau hais lus, cov dej tuav tus nqi ntawm slurry nce nrog qhov nce ntawm cellulose ether cov ntsiab lus.Cov dej tuav cov nyhuv ntawm cellulose ether tuaj yeem tiv thaiv lub substrate los ntawm absorbing dej ntau dhau sai heev, thiab cuam tshuam cov evaporation ntawm cov dej, thiaj li xyuas kom meej tias cov slurry ib puag ncig muab dej txaus rau cement hydration.Tsis tas li ntawd, viscosity ntawm cellulose ether kuj muaj txiaj ntsig zoo rau cov dej tuav ntawm cov tshuaj khib nyiab.Qhov siab dua qhov viscosity, qhov dej tuav tau zoo dua.Feem ntau, cellulose ether nrog viscosity ntawm 400mpa.s feem ntau yog siv rau hauv tus kheej-leveling mortar, uas tuaj yeem txhim kho qib kev ua tau zoo ntawm mortar thiab ua rau kom muaj kev sib haum xeeb ntawm mortar.
