Self leveling mortar tuaj yeem tso siab rau nws tus kheej qhov hnyav los tsim lub hauv paus tiaj tus, du, thiab ruaj khov ntawm lub substrate rau nteg lossis khi lwm yam ntaub ntawv, thiab tseem tuaj yeem nqa tawm qhov loj thiab siv tau zoo. Yog li ntawd, high fluidity yog ib qho tseem ceeb heev feature ntawm tus kheej leveling mortar; Tsis tas li ntawd, nws tseem yuav tsum muaj qee qhov kev tuav dej thiab kev sib khi lub zog, tsis muaj qhov tshwm sim ntawm cov dej sib cais, thiab muaj cov yam ntxwv ntawm kev rwb thaiv tsev thiab qhov kub thiab txias. Feem ntau, tus kheej leveling mortar yuav tsum muaj fluidity zoo, tab sis qhov tseeb fluidity ntawm cement slurry feem ntau tsuas yog 10-12cm; Cellulose ether yog ib qho tseem ceeb additive nyob rau hauv npaj-mixed mortar. Txawm hais tias tus nqi ntxiv yog tsawg heev, nws tuaj yeem txhim kho qhov kev ua tau zoo ntawm cov mortar. Nws tuaj yeem txhim kho qhov sib xws, kev ua haujlwm, kev sib koom ua ke, thiab kev tuav dej ntawm cov mortar. Nws plays lub luag hauj lwm tseem ceeb heev nyob rau hauv lub teb ntawm premix mortar.

1. Liquidity
Cellulose ether muaj qhov cuam tshuam loj rau kev tuav dej, sib xws, thiab kev tsim kho ntawm tus kheej qib mortar. Tshwj xeeb tshaj yog raws li tus kheej leveling mortar, flowability yog ib qho ntawm cov cim tseem ceeb rau kev ntsuam xyuas tus kheej leveling kev ua tau zoo. Nyob rau ntawm qhov chaw ntawm kev ua kom ntseeg tau qhov qub muaj pes tsawg leeg ntawm mortar, fluidity ntawm mortar tuaj yeem hloov kho los ntawm kev hloov cov koob tshuaj ntawm cellulose ether. Txawm li cas los xij, ntau npaum li cas tuaj yeem txo qhov fluidity ntawm mortar, yog li kev noj ntawm cellulose ether yuav tsum tau tswj nyob rau hauv qhov tsim nyog ntau.

2. Kev tuav dej
Cov dej tuav ntawm mortar yog qhov taw qhia tseem ceeb los ntsuas qhov ruaj khov ntawm cov khoom siv sab hauv ntawm cov cement mortar tshiab. Txhawm rau ua kom cov khoom siv gel muaj dej txaus, qhov tsim nyog ntawm cellulose ether tuaj yeem tswj cov dej noo hauv cov tshuaj khib nyiab rau lub sijhawm ntev. Feem ntau hais lus, cov dej tuav tus nqi ntawm cov 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 los yog sai heev, thiab cuam tshuam cov dej evaporation, yog 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 tseem muaj feem cuam tshuam rau cov dej tuav ntawm mortar. Qhov siab dua qhov viscosity, qhov dej tuav tau zoo dua. Cellulose ether nrog viscosity dav dav ntawm 400mpa. s feem ntau yog siv rau hauv tus kheej-leveling mortar, uas tuaj yeem txhim kho qhov kev ua tau zoo thiab compactness ntawm mortar.
