Dab tsi yog Redispersible Polymer Powder?

Redispersible polymer hmoov (RDP) yog ib hom polymer hmoov uas tuaj yeem hloov pauv hauv dej los tsim kom muaj kev sib cais ruaj khov lossis emulsion.Nws yog cov hmoov qhuav uas yog tsim los ntawm cov tshuaj tsuag-qhuav ib lub polymer emulsion.RDP yog siv nyob rau hauv ntau yam kev siv, nrog rau kev tsim kho, nplaum, txheej, thiab sealants.

RDP yog tsim los ntawm ntau yam polymers, xws li acrylics, polyvinyl acetate (PVA), polyvinyl cawv (PVOH), thiab styrene-butadiene (SBR).Cov polymers feem ntau yog sib xyaw ua ke los tsim cov hmoov uas xav tau.Tom qab ntawd cov hmoov yog tshuaj tsuag-qhuav los ua cov hmoov qhuav.Tom qab ntawd cov hmoov tuaj yeem hloov pauv hauv dej los tsim kom muaj kev ruaj khov los yog emulsion.

RDP yog siv nyob rau hauv ntau yam kev siv, nrog rau kev tsim kho, nplaum, txheej, thiab sealants.Hauv kev tsim kho, RDP yog siv los ua ib qho ntxiv hauv cov cement-based mortars thiab plasters.Nws txhim kho kev ua haujlwm, adhesion, thiab dej tsis kam ntawm mortar lossis plaster.Hauv cov nplaum nplaum, RDP yog siv los txhim kho cov nplaum ntawm cov nplaum rau hauv substrate.Hauv cov txheej txheem, RDP yog siv los txhim kho cov dej tsis kam thiab hloov tau yooj yim ntawm txheej.Hauv cov sealants, RDP yog siv los txhim kho cov adhesion thiab yooj ntawm sealant.

RDP kuj tseem siv tau rau ntau yam kev siv, xws li cov ntawv txheej, cov txheej tawv tawv, thiab cov ntaub ntawv txheej.Hauv cov ntawv txheej, RDP yog siv los txhim kho cov dej tsis kam thiab lub zog ntawm daim ntawv.Hauv cov txheej txheem tawv tawv, RDP yog siv los txhim kho cov dej tsis kam thiab hloov pauv ntawm tawv.Hauv textile coatings, RDP yog siv los txhim kho cov dej tsis kam thiab hloov pauv ntawm cov ntaub.

RDP yog ntau yam khoom siv uas siv ntau yam kev siv.Nws yog cov hmoov qhuav uas tuaj yeem hloov pauv hauv dej los tsim kom muaj kev ruaj khov dispersion lossis emulsion.RDP yog siv rau hauv kev tsim kho, nplaum, txheej, thiab sealants los txhim kho kev ua haujlwm, adhesion, thiab dej tsis kam ntawm cov khoom.RDP kuj tseem siv tau rau ntau yam kev siv, xws li cov ntawv txheej, cov txheej tawv tawv, thiab cov ntaub ntawv txheej.
