RD hmoov ua li cas?

RD hmoov yog ib hom redispersible polymer hmoov uas yog siv nyob rau hauv ntau yam kev lag luam daim ntaub ntawv.Nws yog tsim los ntawm kev sib xyaw ua ke ntawm polymers thiab lwm yam khoom siv, xws li fillers, additives.Cov hmoov feem ntau yog siv los ua cov txheej los yog cov khoom ntxiv hauv kev tsim cov khoom xws li xim, txheej, nplaum, thiab sealants.

Cov txheej txheem ntawm kev ua RD hmoov muaj ob peb kauj ruam.Ua ntej, cov khoom siv raw yog hnyav thiab sib xyaw ua ke hauv ib qho khoom tov.Cov ntaub ntawv yog ces rhuab mus rau ib tug tshwj xeeb kub thiab tov rau ib tug tej lub sij hawm.Cov txheej txheem no yuav pab kom ntseeg tau tias cov khoom xyaw raug muab sib xyaw kom zoo thiab cov khoom xav tau ntawm cov hmoov ua tiav.

Thaum cov sib tov twb tov lawm, nws yog ces txias rau chav tsev kub.Cov sib tov txias yog ces dhau los ntawm lub tshuab milling los tsim cov hmoov zoo.Cov hmoov yog ces sieved kom tshem tawm tej yam loj hais thiab xyuas kom meej tias cov hmoov muaj qhov xav tau particle loj.

Cov kauj ruam tom ntej ntawm tus txheej txheem yog ntxiv ib qho ntxiv additives lossis fillers rau cov hmoov.Cov additives no tuaj yeem siv los txhim kho cov khoom ntawm cov hmoov lossis ntxiv xim lossis lwm yam uas xav tau.Tom qab ntawd cov additives yog tov rau hauv cov hmoov thiab cov sib tov yog ces dhau los ntawm lub tshuab milling los tsim ib homogeneous hmoov.
