Nws yog tsim nyog los ntxivredispersible polymer hmoovrau cov cement qhuav mortar, vim hais tias cov redispersible polymer hmoov mas muaj 6 qhov zoo hauv qab no, cov hauv qab no yog cov lus qhia rau koj.
1. Txhim kho cov nplaum nplaum thiab cohesion
Redispersible polymer hmoov muaj txiaj ntsig zoo rau kev txhim kho lub zog sib txuas thiab cohesion ntawm cov khoom.Vim yog kev nkag mus ntawm cov khoom siv polymer rau hauv qhov pores thiab capillaries ntawm cov cement matrix, kev sib koom ua ke zoo yog tsim nrog cov cement tom qab hydration.Lub polymer resin nws tus kheej muaj cov khoom zoo heev.Lub adhesion ntawm cement mortar khoom yog pom tseeb dua nyob rau hauv kev txhim kho cov adhesion ntawm cement mortar khoom rau substrates, tshwj xeeb tshaj yog cov neeg pluag adhesion ntawm inorganic binders xws li cov cement rau ntoo, fiber, PVC, EPS thiab lwm yam organic substrates.
2. Txhim kho khov-thaw stability thiab zoo tiv thaiv cov khoom tawg
Redispersible latex hmoov, cov yas ntawm nws cov thermoplastic resin, tuaj yeem kov yeej qhov kev puas tsuaj ntawm thermal expansion thiab contraction los ntawm qhov kub thiab txias sib txawv rau cov ntaub ntawv cement mortar.Kev kov yeej cov yam ntxwv ntawm qhov loj kom qhuav shrinkage thiab yooj yim tawg ntawm cov cement mortar yooj yim, nws tuaj yeem ua rau cov khoom hloov tau yooj yim, yog li txhim kho cov khoom siv mus ntev.
3. Txhim kho khoov thiab tensile kuj
Nyob rau hauv lub pob txha pob txha tsim los ntawm hydration ntawm cement mortar, lub polymer zaj duab xis yog elastic thiab tawv.Nyob nruab nrab ntawm cov cement mortar hais, nws ua haujlwm zoo li lub zog sib koom ua ke, uas tuaj yeem tiv taus siab deformation loads thiab txo qhov kev ntxhov siab, ua rau Tensile thiab khoov kuj zoo dua.
4. Txhim kho qhov cuam tshuam
Redispersible latex hmoov yog cov thermoplastic cob.Nws yog ib tug mos mos zaj duab xis coated rau ntawm qhov chaw ntawm lub mortar hais, uas muaj peev xwm nqus tau cov kev cuam tshuam ntawm sab nraud quab yuam thiab so kom txaus yam tsis muaj kev tawg, yog li txhim kho qhov kev cuam tshuam ntawm mortar.
5. Txhim kho hydrophobicity thiab txo qhov nqus dej
Ntxiv cocoa dispersible polymer hmoov tuaj yeem txhim kho microstructure ntawm cement mortar.Nws cov polymer tsim ib qho kev sib txuas tsis tau hauv cov txheej txheem ntawm cov cement hydration, kaw cov capillaries hauv cov cement gel, thaiv cov dej nkag, thiab txhim kho impermeability.
6. Txhim kho hnav tsis kam thiab ua haujlwm ntev
Qhov sib ntxiv ntawm redispersible latex hmoov tuaj yeem ua rau kom muaj kev sib raug zoo ntawm cov cement mortar hais thiab cov zaj duab xis polymer.Kev txhim kho ntawm lub zog cohesive sib raug zoo txhim kho lub peev xwm ntawm cov tshuaj khib nyiab kom tiv taus kev ntxhov siab, kom tus nqi hnav raug txo, kev hnav tsis kam yog txhim kho, thiab kev pab cuam lub neej ntawm lub mortar ntev.
