Thaum cov hmoov yas li cas yog ntxiv rau cov xis mas pob zeb ua tau, cov yeeb yaj kiab polymer tuaj yeem txo tus lej thiab qhov loj me ntawm cov dej noo. Qhov kev ywg dej no yog qhov tshwj xeeb tshaj yog cov qauv dej noo uas nquag muaj cov dej, xws li cov chav dej xws li pas dej, ua luam dej, thiab hauv qab no. Cov hmoov yas looj xwb tsis tuaj yeem tiv thaiv noo noo ntawm kev nkag mus rau cov hlau tuav los ntawm cov qauv hlau thiab txhim kho lub durability ntawm cov qauv txheej txheem.
Redispersible looj hmoov kuj tseem tuaj yeem txhim kho kev tsim kho kev tsim kho ntawm cov khoom noj qabent-based. Vim tias nws cov ntaub pua chaw zoo, lub cug tom qab ntxiv cov hmoov looj kom zoo dua thiab ua haujlwm zoo thaum kev tsim kho. Qhov no txhais tau tias kev tsim cov neeg ua haujlwm tuaj yeem yooj yim nteg thiab kho cov khoom siv, ua kom muaj kev ua haujlwm zoo thiab txo cov khib nyiab thaum kev tsim kho. Cov xeeb ceem no cov hmoov yas tau pom tseeb rau kev tsim kho lossis kev tsim kho cov qauv nyuaj.
Daim ntawv thov ntawm Redispersible looj cov hmoov kuj tseem cuam tshuam hauv kev txhim kho cov khoom zoo thiab zoo nkauj ntawm cov ntaub ntawv. Cov hmoov yas yas tuaj yeem pab cov tshuaj khib ua ib qho chaw tiaj thiab du tom qab qhov tseem ceeb rau qee qhov kev kho kom zoo nkauj, xws li tig lub tshuaj khib thiab sab nraud phab ntsa tsho. Ntxiv rau, cov hmoov yas looj tau kuj tseem tuaj yeem txhim kho cov xim khaws kev tshuaj khib, ua kom pom cov tsev ntau dua thiab zoo nkauj.
Los ntawm kev pom txog kev tiv thaiv ib puag ncig thiab kev txhim kho kom ruaj khov, daim ntawv thov ntawm redispersible looj hmoov kuj muaj qhov tseem ceeb. Vim tias nws tuaj yeem txo qis kev siv cov cement, yog li txo cov pa roj carbon monissions. Ib qho ntxiv, nws tseem tuaj yeem siv cov khoom lag luam los ntawm cov khoom siv raw, cov khoom siv txo qis, uas yog nyob rau hauv cov kev tawm tswv yim ntsuab los ntawm kev tsim kho kev tsim kho.
Redispersible yas hmoov ua lub luag haujlwm tseem ceeb hauv ntau yam uas yog phau ntawv hauv cov tshuab city-raws li. Nws tsis yog txhim kho cov khoom siv ntawm lub zog, hloov tsis taus thiab dej tsis kam, tab sis kuj tseem txhim kho kev tsim kho kev tsim kho thiab nto zoo. Nyob rau tib lub sijhawm, nws daim ntawv thov kuj tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm kev txhim kho kom ruaj khov. Nyob rau hauv lub neej yav tom ntej, nrog kev nce qib nro ntawm kev siv thev naus laus zis thiab kev nce qib ntxiv rau kev siv hluav taws xob ib puag ncig hauv kev tsim kho kom dav.
