Redispersible polymer hmoov yog tshuaj tsuag-qhuav hmoov ntawm polymer emulsion raws liethylene-vinyl acetate copolymer. Nws yog ib qho tseem ceeb ntawm cov khoom siv niaj hnub drymix mortar. Dab tsi cuam tshuam rauredispersible polymer hmoovmuaj nyob rau hauv lub tsev mortar?
Lub redispersible polymer hmoov particles sau cov kab noj hniav ntawm lub mortar, qhov ceev ntawm lub mortar yog nce, thiab hnav kuj zoo tuaj. Nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam, nws yuav tsim kev so tsis muaj kev puas tsuaj. Cov yeeb yaj kiab polymer tuaj yeem khaws cia rau hauv qhov system mortar.
1. Txhim kho kev ua haujlwm ntawm kev siv tshuaj khib nyiab
Tom qab redispersible latex hmoov raws li ib tug organic binder yog tsim rau hauv ib zaj duab xis, nws muaj peev xwm tsim high tensile zog thiab cohesive lub zog ntawm txawv substrates. Ua lub luag haujlwm tseem ceeb hauv kev adhesion ntawm mortar rau cov khoom siv organic (EPS, extruded foam board) thiab du nto substrates. Cov zaj duab xis-forming polymer hmoov yog muab faib thoob plaws hauv lub mortar system raws li ib tug reinforcing khoom los ua kom cov cohesion ntawm lub mortar.
2. Txhim kho huab cua tsis kam, khov-thaw kuj thiab tawg tsis kam ntawm mortar
Redispersible polymer hmoov yog cov thermoplastic resin nrog kev yooj yim zoo, uas tuaj yeem ua rau cov mortar tiv thaiv qhov kev hloov ntawm sab nraud txias thiab kub ib puag ncig, thiab tiv thaiv cov mortar los ntawm kev tawg vim qhov kev hloov ntawm qhov kub thiab txias.
3. Txhim kho hydrophobicity ntawm mortar thiab txo qhov nqus dej
Cov hmoov polymer redispersible tsim ib zaj duab xis nyob rau hauv kab noj hniav thiab nto ntawm lub mortar, thiab cov polymer zaj duab xis yuav tsis disperse dua tom qab raug mus rau dej, uas tiv thaiv cov intrusion ntawm dej thiab txhim kho impermeability. Tshwj xeebredispersible latex hmoovnrog cov nyhuv hydrophobic muaj cov nyhuv hydrophobic zoo dua.
4. Txhim kho qhov khoov lub zog thiab flexural zog ntawm mortar
Polymer zaj duab xis tsim los ntawm redispersible polymer hmoov muaj qhov yooj yooj yim. Cov yeeb yaj kiab tau tsim nyob rau hauv qhov khoob thiab qhov chaw ntawm cov cement mortar particles los tsim kev sib txuas yooj yim. Yog li, lub nkig thiab tawv cement mortar ua elastic. Lub mortar nrog ntxiv tus nqi ntawm redispersible polymer hmoov yog ob peb zaug siab dua li cov mortar zoo tib yam nyob rau hauv cov nqe lus ntawm tensile thiab dabtsi yog khoov kuj.
Longou compay, ua tus thawj cojRDP Hoobkasnyob rau hauv Suav teb, yog ib txwm tsom rau kev muab cov khoom zoo thiab cov kev daws teeb meem hauvdrymix mortar. Txais tos tiv tauj peb kom paub meej cov ntaub ntawv ntau ntxiv.
