Cov khoom twg ntawm cov mortar tuaj yeem ua rau cov hmoov polymer redispersible zoo dua?

Cov hmoov polymer uas tawg tau dua (RPP) feem ntau siv rau hauv cov qauv mortar los txhim kho ntau yam khoom thiab cov yam ntxwv ntawm kev ua tau zoo. Nov yog qee qhov khoom tseem ceeb ntawm mortar uas RPP tuaj yeem txhim kho:

1. Kev nplaum: RPP txhim kho qhov kev nplaum ntawm cov mortar rau cov substrates xws li concrete, masonry, ntoo, thiab hlau. Qhov kev nplaum zoo no pab tiv thaiv kev tawg thiab ua kom muaj kev sib txuas zoo ntawm cov mortar thiab cov substrate.
2. Lub Zog Flexural: Kev koom ua ke RPP rau hauv cov qauv mortar tuaj yeem ua rau lub zog flexural nce ntxiv, ua rau cov mortar tiv taus kev tawg thiab deformation. Qhov no tseem ceeb heev rau cov ntawv thov uas lub substrate yuav muaj kev txav mus los lossis thermal nthuav dav thiab contraction.
3. Kev Khaws Dej: RPP ua kom cov khoom khaws dej ntawm cov pob zeb ua kom zoo dua, ua rau cov khoom siv cementitious noo tau ntev. Qhov no ua rau ua haujlwm tau zoo dua, qhib tau ntev dua, thiab lo rau zoo dua, tshwj xeeb tshaj yog thaum kub lossis cua hlob.
4. Kev Ua Haujlwm Tau: RPP txhim kho kev ua haujlwm tau thiab kev sib xws ntawm cov mortar, ua rau nws yooj yim dua rau kev sib tov, siv, thiab nthuav. Qhov no tso cai rau kev npog zoo dua thiab kev siv sib xws ntau dua, txo qhov yuav muaj qhov khoob lossis qhov sib txawv hauv cov mortar tiav lawm.
5. Txo Qhov Ntsws Thiab Kev Nthuav Dav: Los ntawm kev txhim kho kev nplaum, kev ywj pheej, thiab kev khaws dej, RPPs pab txo qhov ntsws thiab kev tawg hauv cov mortar. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas qhov ntswg tawg tuaj yeem ua rau lub mortar ruaj khov thiab ruaj khov.
6. Kev Ruaj Khov: Kev siv RPP tuaj yeem ua kom lub mortar ruaj khov dua los ntawm kev ua kom nws tiv taus huab cua, tshuaj lom neeg tawm tsam, thiab kev sib txhuam. Qhov no ua rau lub mortar kav ntev dua uas tswj tau nws cov qauv zoo li qub.
7. Kev Tiv Thaiv Kub thiab Dej noo: RPP tuaj yeem txhim kho qhov kev tiv thaiv kub thiab dej noo ntawm cov mortar, ua rau nws tsim nyog siv rau ntau yam xwm txheej ib puag ncig, suav nrog cov voj voog khov-thaw, av noo siab, thiab qhov kub thiab txias hloov pauv.
8. Lub Zog Sib Txuas: RPP pab txhawb rau lub zog sib txuas ntawm cov mortar, ua kom muaj kev sib txuas zoo ntawm cov txheej mortar thiab ntawm cov mortar thiab cov substrate. Qhov no yog qhov tseem ceeb rau kev ua tiav kev sib dhos ua vaj tse txhim khu kev qha thiab kav ntev.

Kev siv cov hmoov polymer uas tawg tau dua tshiab rau hauv cov qauv mortar muaj ntau yam txiaj ntsig, suav nrog kev txhim kho kev nplaum, lub zog khoov, kev khaws dej, kev ua haujlwm tau zoo, kev ruaj khov, thiab kev tiv taus kev ntsws, kev tawg, thiab cov yam ntxwv ib puag ncig. Cov kev txhim kho no ua rau RPP-modified mortars haum rau ntau yam kev siv hauv kev tsim kho, suav nrog kev teeb tsa pobzeb, stucco thiab plastering, kev kho thiab kev kho dua tshiab, thiab kev tiv thaiv dej.
