Cov hmoov polymer uas tawg tau dua tuaj yeem txhim kho nws txoj kev yooj yim hauv kev tsim kho thiab cov yam ntxwv ntawm kev tsim zaj duab xis, thiab txo qhov tawg thiab delamination.
Lub kaw lus mortar rwb thaiv tsev (xws li EIFS sab nraud phab ntsa rwb thaiv tsev system) Ntxiv Redispersible polymer hmoov rau hauv lub rwb thaiv tsev mortar tuaj yeem txhim kho qhov kev sib txuas ntawm mortar thiab substrate (xws li ua npuas ncauj board, polystyrene board, thiab lwm yam), txhim kho kev tiv thaiv tawg, tiv thaiv te thiab ntev lub neej kev pabcuam ntawm lub kaw lus.
Cov tshuaj nplaum tiv thaiv dej Siv RDP hauv cov mis tshuaj nplaum tiv thaiv dej tuaj yeem ua rau cov khoom siv yooj ywm thiab tsis nkag tau zoo dua, yog li nws tuaj yeem tswj nws cov kev ua tau zoo hauv qhov chaw ntub dej thiab tiv tauj dej ntev.
Cov tshuaj pleev kho thiab cov neeg sawv cev sib txuas Cov hmoov polymer uas tawg dua tshiab tuaj yeem txhim kho qhov kev sib txuas thiab kev ywj pheej ntawm cov tshuaj pleev kho kom tsis txhob muaj kab nrib pleb hauv thaj chaw kho. Ntxiv RDP rau tus neeg sawv cev sib txuas tuaj yeem txhim kho lub zog sib txuas ntawm cov txheej sib txawv ntawm cov ntaub ntawv.
Cov ntaub ntawv ua los ntawm gypsum Siv cov hmoov polymer Redispersible hauv cov txheej txheem leveling gypsum thiab cov gypsum binders tuaj yeem txhim kho lawv lub zog sib txuas, kev tiv thaiv tawg thiab kev ua haujlwm ntawm kev tsim kho, thiab yog ib feem tseem ceeb ntawm cov ntaub ntawv tsim kho ntsuab.
3. Cov txiaj ntsig ntawm daim ntawv thov
Kev Tsim Kho Yooj Yim Cov hmoov polymer uas tawg tau feem ntau yog cov hmoov qhuav thiab tuaj yeem sib xyaw ncaj qha nrog lwm cov khoom qhuav (xws li cement, xuab zeb, thiab lwm yam) yam tsis tas yuav kho emulsification ntxiv. Nws tuaj yeem siv rau ntawm qhov chaw los ntawm kev ntxiv dej, uas yooj yim rau kev thauj mus los thiab kev tsim kho.
Txhim kho kev ua tau zoo tag nrho Nws tsis yog tsuas yog txhim kho kev ua tau zoo ntawm cov mortar, tab sis kuj txhim kho nws cov khoom siv lub cev xws li kev tiv thaiv kab nrib pleb, kev tiv thaiv te, kev tiv thaiv hnav thiab kev ywj pheej. Nws yog ib qho tseem ceeb ntxiv rau kev txhim kho qhov zoo ntawm cov ntaub ntawv tsim kho.
Kev tiv thaiv ib puag ncig thiab kev nyab xeeb Cov hmoov polymer uas tawg tau dua tshiab tsis muaj tshuaj lom thiab tsis ua rau muaj kev phom sij, ua tau raws li qhov yuav tsum tau ua ntawm cov tsev niaj hnub rau kev tiv thaiv ib puag ncig thiab cov pa phem VOC tsawg, thiab siv ntau ntxiv hauv cov tsev ntsuab.
