Cov hmoov latex uas tawg tau dua yog siv rau hauv ib qho khoom JS txheej tiv thaiv dej, polystyrene board bonding mortar rau kev rwb thaiv tsev, flexible surface protection mortar, polystyrene particle thermal insulation coating, vuas nplaum, self-leveling mortar, dry-mixed mortar, putty, thiab lwm yam. Kev hloov kho cov ntaub ntawv inorganic gelling tau siv dav.
Ntxiv cov hmoov latex uas yaj tau dua rau hauv cov hmoov putty tuaj yeem ua rau nws lub zog ntxiv, muaj kev sib txuas zoo thiab cov khoom siv kho tshuab, thiab pab txhim kho qhov nyuaj. Nws muaj kev tiv thaiv dej zoo, permeability, thiab ruaj khov zoo heev. Alkaline, tsis yooj yim hnav, thiab tuaj yeem txhim kho kev khaws dej, ua kom lub sijhawm qhib ntev dua, thiab txhim kho kev ruaj khov.
Thaum cov hmoov latex uas rov tawg tau raug do kom sib npaug hauv cov hmoov putty thiab sib xyaw nrog dej, nws raug faib ua cov khoom me me polymer; cov cement gel maj mam tsim los ntawm kev pib hydration ntawm cement, thiab cov kua theem yog tsim los ntawm Ca (OH) 2 hauv cov txheej txheem hydration. Saturated, thaum cov hmoov latex tsim cov khoom polymer thiab cov khoom tso rau ntawm qhov chaw ntawm cov cement gel / unhydrated cement particle sib tov; thaum cov cement tau hydrated ntxiv, cov dej hauv cov hlab ntsha txo qis, thiab cov khoom polymer maj mam txwv tsis pub nyob hauv cov hlab ntsha. Cov nplaum / unhydrated cement particle sib tov thiab qhov chaw sau ua ib txheej kaw-ntim; nyob rau hauv qhov kev ua ntawm hydration reaction, txheej puag absorption thiab nto evaporation, cov dej raug txo qis ntxiv, thiab cov txheej stacked tsim sib sau ua ke rau hauv ib zaj duab xis, uas khi cov khoom hydration reaction hauv Ua ke lawv tsim ib lub network qauv tiav. Lub kaw lus sib xyaw ua ke tsim los ntawm cement hydration thiab latex hmoov zaj duab xis tsim tuaj yeem txhim kho qhov dynamic cracking tsis kam ntawm putty los ntawm kev sib koom ua ke.
Cov putty siv ua txheej hloov pauv ntawm phab ntsa sab nraud rwb thaiv tsev thiab xim yuav tsum tsis txhob muaj zog dua li cov plastering mortar, txwv tsis pub yuav tawg yooj yim. Hauv tag nrho cov txheej txheem rwb thaiv tsev, qhov yooj ywm ntawm cov putty yuav tsum siab dua li ntawm cov khoom siv hauv paus. Ua li no, cov putty tuaj yeem hloov kho tau zoo dua rau qhov deformation ntawm lub substrate thiab buffer nws tus kheej deformation nyob rau hauv qhov kev ua ntawm cov yam ntxwv sab nraud, txo qhov kev ntxhov siab concentration, thiab txo qhov ua tau ntawm kev tawg thiab tev ntawm cov txheej.
