RDP (Redispersible Polymer Hmoov) yog cov hmoov ntxiv uas feem ntau siv rau hauv cov ntaub ntawv siv hauv kev tsim kho, tshwj xeeb tshaj yog cov khoom siv cement xws li mortars, adhesives thiab tile grouts. Nws muaj cov polymer resins (feem ntau yog ua los ntawm vinyl acetate thiab ethylene) thiab ntau yam additives.
RDP hmoov feem ntau yog siv rau cov hom phiaj hauv qab no:
Txhim Kho Kev Ywj Pheej thiab Kev Ruaj Khov: Thaum ntxiv rau cov ntaub ntawv cementitious, RDP ua rau lawv muaj kev ywj pheej, kev ywj pheej thiab kev tiv thaiv tawg. Qhov no tseem ceeb heev rau cov ntawv thov uas cov ntaub ntawv raug kev txav mus los lossis kev co, xws li cov nplaum pobzeb lossis cov plastering sab nraud.
Kev Sib Txuas Zoo Dua: RDP ua rau lub zog sib txuas ntawm cov khoom siv cement thiab cov khoom siv xws li pob zeb, ntoo, pobzeb lossis cov laug cam rwb thaiv tsev nce ntxiv. Nws ua rau kev sib txuas zoo dua thiab txo qhov kev pheej hmoo ntawm kev tawg lossis kev sib cais.
Kev Khaws Dej: RDP pab khaws dej hauv cov cement sib tov, ua rau cov cement noo thiab ua kom cov khoom siv ua haujlwm ntev dua. Qhov no muaj txiaj ntsig zoo rau cov ntawv thov uas xav tau lub sijhawm ua haujlwm ntev dua lossis xav tau kev siv tshuab zoo dua.
Kev ua haujlwm tau zoo dua: RDP ua rau cov khoom siv cement ntws tau zoo dua thiab nthuav dav tau zoo dua, ua rau lawv yooj yim dua rau kev sib tov, tuav thiab siv. Nws ua rau cov mortar ua haujlwm tau zoo dua thiab txo cov haujlwm uas xav tau thaum lub sijhawm tsim kho.
Cuam Tshuam Rau Lub Sijhawm Teeb Tsa: RDP tuaj yeem cuam tshuam rau lub sijhawm teeb tsa ntawm cov khoom siv cementitious, ua rau muaj kev tswj hwm zoo dua ntawm cov txheej txheem teeb tsa. Nws tuaj yeem pab nce lossis txo lub sijhawm teeb tsa uas xav tau rau ib daim ntawv thov tshwj xeeb.
Kev Tiv Thaiv Dej Zoo Dua: RDP ua rau cov khoom siv cement tiv thaiv dej zoo dua, ua rau lawv tiv taus dej nkag mus thiab ua rau lawv ruaj khov dua hauv qhov chaw ntub dej lossis noo noo.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov khoom tshwj xeeb thiab kev ua tau zoo ntawm RDP hmoov yuav txawv nyob ntawm cov khoom sib xyaw polymer, qhov loj me ntawm cov khoom me me, thiab lwm yam. Cov chaw tsim khoom sib txawv tuaj yeem muab cov khoom RDP nrog cov yam ntxwv sib txawv uas tsim rau cov ntawv thov tshwj xeeb.
Zuag qhia tag nrho, RDP hmoov yog cov khoom siv ntau yam rau cov ntaub ntawv tsim kho uas ua rau muaj kev ywj pheej, kev nplaum, kev ua haujlwm yooj yim, kev tiv thaiv dej thiab kev ua haujlwm ntev ntawm cov khoom siv cement.
