Cov khoom sib txawv qhuav hmoov mortar muaj cov kev ua tau zoo sib txawv rau redispersible latex hmoov. Vim tias cov vuas luaj ceramic muaj qhov zoo nkauj zoo nkauj thiab ua haujlwm zoo xws li cov kav ntev, tsis muaj dej thiab tu yooj yim, lawv cov ntawv siv tau ntau heev; pobzeb adhesives yog cement-based bonding cov ntaub ntawv rau pasting vuas, tseem hu ua pobzeb adhesives. Nws tuaj yeem siv los ua cov vuas luaj ceramic, polished vuas thiab cov pob zeb ntuj xws li granite.
Cov pobzeb nplaum yog tsim los ntawm kev sib sau ua ke, Portland cement, me me ntawm slaked txiv qaub thiab ua haujlwm ntxiv ntxiv raws li cov khoom lag luam xav tau. Yav dhau los, tuab-txheej mortar tov rau ntawm qhov chaw tau siv los ua cov khoom sib txuas rau cov vuas thiab pob zeb. Txoj kev no tsis muaj txiaj ntsig, siv ntau cov ntaub ntawv, thiab nyuaj rau kev tsim kho. Thaum sib txuas cov vuas loj nrog cov dej nqus dej tsawg, nws yooj yim rau poob thiab kev tsim kho tsis yooj yim rau lav. Kev siv cov nplais nplaum nplaum ua haujlwm tau zoo tuaj yeem kov yeej cov teeb meem saum toj no, ua kom zoo nkauj ntawm cov nplais ntsej muag zoo meej, nyab xeeb, ceev hauv kev tsim kho, thiab txuag cov khoom siv.
Cov nyhuv ntawm redispersible latex hmoov ntawm freshly mixed mortar nyob rau hauv pobzeb nplaum: ncua sij hawm ua hauj lwm thiab hloov sij hawm; txhim kho cov dej tuav kev ua haujlwm kom ntseeg tau cov cement hydration; txhim kho sag kuj (tshwj xeeb hloov roj hmab hmoov); txhim kho kev ua haujlwm tau zoo (yooj yim rau ntawm substrate, yooj yim rau nias cov vuas rau hauv cov nplaum)
Cov nyhuv ntawm redispersible latex hmoov ntawm hardened mortar nyob rau hauv pobzeb nplaum: nws muaj zoo adhesion rau ntau yam substrates, xws li pob zeb, plaster, ntoo, qub vuas, PVC; nyob rau hauv ntau yam kev nyab xeeb, nws muaj qhov zoo deformability.
Raws li tus nqi ntawm cov cement nce, lub zog qub ntawm cov pobzeb nplaum ntxiv, thiab tib lub sijhawm, lub zog tensile nplaum tom qab tso rau hauv dej thiab lub zog tensile nplaum tom qab tshav kub kuj nce. Nrog rau qhov nce ntawm cov nyiaj redispersible latex hmoov, lub tensile daim ntawv cog lus lub zog ntawm cov pobzeb nplaum tom qab immersion nyob rau hauv dej thiab lub tensile daim ntawv cog lus lub zog tom qab tshav kub laus nce raws li, tab sis lub tensile daim ntawv cog lus lub zog tom qab tshav kub laus nce ntau pom tseeb.
