Redispersible polymer hmoov feem ntau pom nyob rau hauv kev tsim kho raws li cov khoom siv rwb thaiv tsev sab nraud.Nws yog tsuas yog tsim los ntawm polystyrene hais thiab polymer hmoov, yog li nws muaj npe rau nws qhov tshwj xeeb.Hom kev tsim kho polymer hmoov no yog tsim los rau tshwj xeeb ntawm polystyrene hais.Mortar polymer hmoov muaj adhesion zoo, zaj duab xis-tsim khoom, huab cua tsis kam thiab tshuaj stability.
Functional ntau haiv neeg ntawmmortarredispersiblepolymerhmoovkuj txiav txim siab tias nws daim ntawv thov yog qhov dav.Nws feem ntau yog siv rau sab nrauv lossis sab hauv thermal rwb thaiv tsev ntawm cov ntaub npog sab nraud xws li cov phab ntsa sab nraud, polystyrene boards, thiab extruded boards.Lub npog txheej ntawm mortar hmoov tuaj yeem ua rau cov yam ntxwv zoo ntawm cov dej tsis zoo, tiv thaiv hluav taws thiab txuag hluav taws xob.
Dab tsi yog cov kauj ruam tshwj xeeb hauv kev tsim cov mortar thiab polymer hmoov?Cia kuv tham luv luv txog nws los ntawm 3 lub ntsiab lus:
1. Peb yuav tsum tau ntxuav cov plua plav ntawm phab ntsa ua ntej kom lub ntsej muag huv si thiab huv si;
2. Qhov sib piv ntawm qhov sib piv yog raws li hauv qab no → mortar hmoov: dej = 1: 0.3, peb tuaj yeem siv lub tshuab mortar sib tov sib npaug thaum sib tov;
3. Peb siv tau point paste los yog nyias paste txoj kev los paste rau ntawm phab ntsa, thiaj li mus compress rau ib tug tej yam flatness;
Yog xav paub ntxiv txog kev tsim kho, koj tuaj yeem saib yooj yim:
1. Nws yog qhov yooj yim kho ntawm mortar hmoov.Peb yuav tsum xyuas kom meej tias qhov saum npoo ntawm lub rwb thaiv tsev yuav tsum tau pasted yog du thiab ruaj.Yog tias tsim nyog, nws tuaj yeem polished nrog coarse sandpaper.Nyob rau lub sijhawm no, nws yuav tsum tau muab sau tseg tias cov rwb thaiv tsev yuav tsum tau nias kom nruj, thiab lub rooj tsavxwm tuaj yeem yuav tsum tau yaug nrog cov rwb thaiv tsev thiab cov polymer hmoov polystyrene particle rwb thaiv tsev mortar;
2. Thaum peb teeb tsa cov mortar hmoov, peb yuav tsum tau ntxiv dej ncaj qha, thiab tom qab ntawd do rau 5 feeb ua ntej nws tuaj yeem siv tau;
3. Rau kev tsim cov tshuaj mortar, peb yuav tsum tau siv cov hlau tsis muaj steel trowel kom du cov tshuaj tiv thaiv tawg rau ntawm lub rwb thaiv tsev board, nias lub iav fiber ntau mesh daim ntaub rau hauv qhov sov gypsum mortar thiab ua kom nws du.Cov ntaub mesh yuav tsum txuas nrog thiab sib tshooj sib npaug.Qhov dav ntawm daim ntaub iav fiber ntau yog 10cm, daim ntaub iav fiber ntau yuav tsum tau muab tso rau hauv tag nrho, thiab lub thickness ntawm fiber reinforced nto txheej yog li 2 ~ 5cm.
Mortar polymer hmoov yog cov slurry tiav tom qab ntxiv cov hmoov polymer.Nws cov kab nrib pleb kuj zoo heev, uas tuaj yeem tiv thaiv kev yaig ntawm cov pa acidic ntawm phab ntsa, thiab nws tsis yooj yim rau pulverize thiab deliquescence txawm tias tom qab ntub dej.Ntawm qee qhov kev thaiv phab ntsa sab hauv thiab sab nrauv.
