RDP (recispersible polymer hmoov) yog hmoov ntxiv siv hauv cov khoom siv tsim kho xws li Mortars, cov nplaum thiab cov nplais grouts. Nws muaj cov resins polymer (feem ntau yog raws cov vinyl acetate thiab ethylene) thiab ntau yam ntxiv.
RDP hmoov feem ntau yog siv rau cov hom phiaj hauv qab no:
Txhim kho kom tau yooj yim thiab cov khoom siv hluav taws xob: thaum ntxiv rau cov cementitious cov khoom siv, RDP nce lawv yooj yim, elasticity thiab tawg tsis kam. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov ntawv thov uas cov ntaub ntawv uas muaj kev txav lossis kev co kom txav lossis cov pob zeb nplaum lossis sab nrauv plaster.
Txhim kho Adhesion: RDP nce cov nyiaj txhiv nyiaj nruab nrab ntawm cov ntaub ntawv casent ntawm cov khoom siv casent thiab substrates xws li pob zeb ua vaj tse, nplais lossis cov laug cam lossis rwb thaiv tsev. Nws txhim kho adhesion thiab txo qhov kev pheej hmoo ntawm kev cuam tshuam lossis sib cais.
Dej khaws cia: RDP pab khaws cov dej hauv cov sib tov ua keasas, tso cai kom muaj kev haus dej kom zoo ntawm cov khoom noj khoom haus ntawm cov khoom siv. Qhov no tau txais txiaj ntsig hauv cov ntawv thov uas txuas ntxiv ua haujlwm lub sijhawm lossis kev ua haujlwm zoo dua.
Kev ua haujlwm tau zoo: RDP txhim kho kev ntws thiab kev lom zem ntawm cov ntaub ntawv tso cai, ua kom yooj yim sib xyaw, kov thiab siv. Nws txhim kho cov haujlwm ntawm lub tshuaj khib thiab txo cov nqi uas yuav tsum tau ua haujlwm thaum kev tsim kho.
Cuam tshuam kev teeb tsa lub sijhawm: RDP tuaj yeem cuam tshuam lub sijhawm ntawm cov khoom noj kom zoo nkauj, tso cai rau kev tswj hwm ntau dua cov txheej txheem. Nws tuaj yeem pab txhawb kom nce lossis txo lub sijhawm teeb tsa lub sijhawm yuav tsum muaj rau ib daim ntawv thov tshwj xeeb.
Txhim kho cov dej tsis kam: RDP txhim kho cov dej tsis kam ua, ua rau lawv tiv taus dej ntau dua thiab noo ib puag ncig.
Nws yog ib qho tseem ceeb kom nco ntsoov tias cov khoom tshwj xeeb thiab kev ua tau zoo ntawm RDP hmoov yuav txawv nyob ntawm polymer sib xyaw, thiab lwm yam. Cov khoom sib txawv yuav muab RDP cov khoom lag luam nrog cov yam ntxwv sib txawv raws li cov ntawv thov tshwj xeeb.
Zuag qhia tag nrho, RDP hmoov yog ib qho kev tsim muaj zog ntxiv rau kev tsim kho cov khoom siv uas txhim kho kev hloov kho, cov khoom siv adability thiab ruaj khov ntawm cov khoom noj.
