Kev teeb tsa ntawm magnesium oxide (MgO) cov vaj huam sib luag hauv chav huv yog ib txoj haujlwm ua haujlwm, tsis yog ib qho yooj yim splicing txheej txheem. Nws koom nrog kev ua haujlwm zoo raws li cov ntaub ntawv tshawb fawb, kev tsim kho tshuab, thiab cov qauv kev siv tshuab huv huv. Tsuas yog los ntawm kev nkag siab tob txog cov qauv kev tshawb fawb tom qab nws cov khoom siv thiab nruj me ntsis ua raws li cov txheej txheem installation cov ntsiab lus tuaj yeem ua tiav qhov kev cia siab ntawm lub zog, sealing, flatness, thiab huv si durability, yog li muab kev tiv thaiv txhim khu kev qha rau ntau yam kev tsim khoom thiab kev sim ib puag ncig.
1. Cracking ntawm vaj huam sib luag seams lossis sealant detachment: Feem ntau ua rau muaj qhov sib txawv ntawm qhov kub thiab txias ua rau thermal expansion thiab contraction ntawm cov khoom, kev co ntawm lub substrate, tu tsis tiav ua rau txo adhesion, los yog siv cov khoom tsis zoo los yog incompatible sealant. Raws li txoj cai, qhov no tshwm sim los ntawm qhov tsis ua raws li qhov xav tau ntawm cov khoom siv thiab tshuaj lom neeg sib raug zoo rau cov khoom siv sib txuas.
2. Cov vaj huam sib luag tsis sib xws lossis cov pob qij txha tsis sib xws: Qhov no feem ntau tshwm sim los ntawm qhov tsis sib xws ntawm cov substrate joists, me ntsis deformation ntawm cov panels lawv tus kheej, kev teeb tsa tsis raug, lossis tsis sib xws. Qhov no ua txhaum txoj cai ntawm kev sib kis quab yuam thiab sib npaug.
3. Localized bulging los yog deformation ntawm lub rooj tsavxwm: Qhov no tej zaum yuav yog vim lub sij hawm kho tsis txaus (cov tshuaj tiv thaiv sab hauv tsis ruaj khov), ib puag ncig ntub dej ntau dhau, lossis tsis muaj kev kho sealing ntawm tus ntoo khaub lig -section ua rau kom ya raws. Cov hauv paus ntsiab lus yog qhov tsis sib xws ntawm kev ntxhov siab sab hauv lossis tsis zoo tshuaj lom neeg thiab lub cev hloov pauv hauv cov khoom.
