RDP (Redispersible Polymer Powder) yog ib qho tseem ceeb hauv tsev cov khoom siv ntxiv rau hauv cov nplais nplaum. Nws tsis tsuas yog txhim kho kev tsim kho ntawm cov nplais nplaum, tab sis kuj txhim kho lawv cov kav ntev.
1. Qhov cuam tshuam ntawm RDP ntawm kev tsim kho kev ua haujlwm
1.1 Txhim kho kev ua haujlwm
RDP tuaj yeem txhim kho kev ua haujlwm ntawm cov nplais nplaum. Thaum lub sij hawm tsim kho, cov pobzeb nplaum yuav tsum muaj kev ua haujlwm zoo thiab lub sijhawm ua haujlwm kom cov neeg ua haujlwm tau yooj yim thov thiab kho qhov chaw ntawm cov vuas. RDP nce viscosity ntawm cov nplaum los ntawm kev tsim cov yeeb yaj kiab polymer, ua kom yooj yim rau kev thov thiab tsis tshua muaj dej ntws, yog li txhim kho kev ua haujlwm thiab kev tsim kho kom zoo.
1.2 Txhim kho kev tuav dej
Kev tuav dej yog qhov tseem ceeb cuam tshuam rau kev tsim kho ntawm cov nplais pobzeb adhesives. Kev tuav dej zoo ua kom ntev lub sijhawm qhib ntawm pobzeb nplaum, muab sijhawm txaus rau kev hloov kho thiab qhov chaw. Kev taw qhia ntawm RDP tuaj yeem txhim kho cov dej tuav lub peev xwm ntawm cov nplaum, txo cov dej tsis zoo, tiv thaiv cov nplaum los ntawm kev ziab ntxov ntxov thaum lub sij hawm tsim kho, thiab ua kom muaj kev vam meej ntawm kev tsim kho.
1.3 Txhim kho adhesion
Cov txheej txheem polymer network tsim los ntawm RDP hauv cov nplaum tuaj yeem txhim kho lub zog sib txuas ntawm cov nplais nplaum. Thaum lub sij hawm tsim kho, cov nplaum yuav tsum tau ua kom ruaj khov rau lub hauv paus txheej thiab cov nplais pobzeb saum npoo los tiv thaiv cov vuas ceramic los ntawm kev poob los yog hollowing. RDP txhim kho cov nplaum lub zog ntawm cov nplaum, tso cai rau nws ua kom zoo dua rau ntau yam substrates thiab txhim kho kev tsim kho kom zoo.
2. Qhov cuam tshuam ntawm RDP ntawm kev ua haujlwm ntev
2.1 Txhim kho dej tsis kam
Ceramic pobzeb nplaum yuav tsum muaj cov dej tsis zoo thaum lub sijhawm siv mus ntev los tiv thaiv cov nplaum tsis ua haujlwm vim kev nkag mus ntawm cov dej noo. Cov yeeb yaj kiab polymer tsim los ntawm RDP hauv cov nplaum nplaum muaj cov dej zoo heev, tuaj yeem tiv thaiv kev ya raws, ua kom muaj kev ruaj ntseg thiab ruaj khov ntawm cov nplaum, thiab txuas ntxiv lub neej kev pab cuam ntawm cov vuas ceramic.
2.2 Txhim khu kev tiv thaiv tawg
RDP tuaj yeem txhim kho qhov yooj yim thiab tawg tsis kam ntawm cov nplais nplaum. Thaum siv, pobzeb nplaum yuav cuam tshuam los ntawm kev hloov pauv kub thiab sab nraud quab yuam, ua rau tawg lossis tawg. RDP txhim kho qhov yooj yim ntawm cov nplaum, txhim kho nws lub peev xwm los tiv thaiv kev ntxhov siab sab nraud, txo qhov tshwm sim ntawm kev tawg, thiab ua kom muaj kev ruaj ntseg ntev ntawm cov vuas ceramic.
2.3 Txhim kho alkali tsis kam
Cov ntaub ntawv hauv tsev feem ntau muaj qee yam ntawm cov tshuaj alkaline, uas tuaj yeem ua rau cov nplais nplaum nplaum thiab cuam tshuam rau nws cov kav ntev. Kev taw qhia ntawm RDP tuaj yeem txhim kho cov alkali tsis kam ntawm cov nplaum, tiv thaiv kev puas tsuaj rau cov nplaum los ntawm cov tshuaj alkaline, thiab tswj nws lub sijhawm ntev thiab ruaj khov.
2.4 UV tiv taus
UV hluav taws xob yog qhov tseem ceeb cuam tshuam rau kev ua haujlwm ntawm cov khoom siv hauv tsev. Lub sij hawm ntev raug rau UV rays tuaj yeem ua rau cov khoom laus thiab kev ua haujlwm tsis zoo. RDP tuaj yeem muab qee yam kev tiv thaiv UV, txo qis kev laus ntawm cov nplaum, thiab tswj kev ruaj ntseg ntawm nws qhov kev ua tau zoo.
RDP muaj kev txhim kho tseem ceeb ntawm kev tsim kho kev ua haujlwm thiab ua haujlwm ntev ntawm cov nplais nplaum. Los ntawm kev txhim kho kev ua haujlwm, txhim kho dej tuav thiab txhim kho adhesion, RDP tuaj yeem txhim kho daim ntawv thov kev ua tau zoo thiab zoo ntawm cov nplais nplaum. Nyob rau tib lub sijhawm, RDP tuaj yeem txhim kho cov dej tsis kam, tawg tsis kam, alkali tsis kam thiab UV tsis kam ntawm cov nplaum, ua kom nws lub neej ua haujlwm ntev thiab ua kom muaj kev ruaj ntseg ntev ntawm cov pobzeb ceramic paving. Nrog rau kev txhim kho txuas ntxiv ntawm kev tsim kho thev naus laus zis, daim ntawv thov ntawm RDP hauv cov nplais nplaum yuav ua tau ntau dua, muab kev txhawb zog rau kev tsim kho kev lag luam.
