Nyob rau hauv cov nqe lus ntawm flexural thiab compressive zog, nyob rau hauv cov xwm txheej ntawm qhov tsis tu ncua dej-cement piv thiab huab cua cov ntsiab lus, tus nqi ntawm latex hmoov muaj ib tug muaj zog lub zog ntawm flexural thiab compressive lub zog ntawm cov cement-raws li cov ntaub ntawv hauv pem teb.Nrog rau qhov nce ntawm latex hmoov cov ntsiab lus, lub zog compressive txo qis me ntsis, thaum lub zog flexural nce ntxiv, uas yog, qhov sib piv folding (compressive zog / flexural zog) maj mam txo.Qhov no qhia tau hais tias qhov brittleness ntawm tus kheej-leveling cov ntaub ntawv hauv pem teb txo qis nrog qhov nce ntawm cov hmoov latex.Qhov no yuav txo cov modulus ntawm elasticity ntawm tus kheej-leveling cov ntaub ntawv hauv pem teb thiab ua rau nws tsis kam mus tawg.
Nyob rau hauv cov nqe lus ntawm daim ntawv cog lus lub zog, txij li thaum tus kheej-leveling txheej yog ib tug thib ob txheej ntxiv;kev tsim kho thickness ntawm tus kheej-leveling txheej feem ntau yog nyias dua li ntawm cov mortar zoo tib yam;Lub leveling txheej yuav tsum tau tiv thaiv thermal stress ntawm cov khoom sib txawv;Qee lub sij hawm tus kheej-leveling cov ntaub ntawv yog siv rau cov khoom tshwj xeeb xws li lub hauv paus qhov chaw uas nyuaj rau ua raws li: Yog li ntawd, txawm tias muaj kev pabcuam cuam tshuam ntawm cov neeg ua haujlwm kho mob, txhawm rau xyuas kom meej tias cov txheej txheem ntawm tus kheej tuaj yeem txuas rau saum npoo. rau ib lub sij hawm ntev Nyob rau hauv lub hauv paus txheej, ntxiv ib tug npaum li cas ntawm latex hmoov yuav ua kom lub sij hawm ntev thiab txhim khu kev qha adhesion ntawm tus kheej-leveling khoom.
Txawm hais tias nws yog nyob rau ntawm lub hauv paus absorbent (xws li kev lag luam pob zeb, thiab lwm yam), lub hauv paus organic (xws li ntoo) lossis lub hauv paus tsis nqus dej (xws li hlau, xws li lub nkoj nkoj), lub zog ntawm cov khoom siv. tus kheej-leveling cov khoom sib txawv nrog tus nqi ntawm cov hmoov latex.Ua ib qho piv txwv, qhov tsis ua tiav ntawm daim ntawv cog lus lub zog ntsuas ntawm tus kheej-leveling cov khoom sib xyaw nrog cov hmoov latex tag nrho tshwm sim nyob rau hauv cov khoom siv tus kheej los yog nyob rau hauv lub hauv paus nto, tsis nyob rau hauv lub interface, qhia tias nws cohesiveness zoo. .
