Yuav ua li cas lub putty hmoov additive redispersible latex hmoov txhim kho lub zog ntawm daim ntawv cog lus?

Nyob rau hauv kev tsim cov hmoov putty, peb yuav tsum tau siv redispersible latex hmoov. Kev siv cov hmoov latex no tuaj yeem ua kom lub zog sib txuas. Peb paub tias yog tias peb xav tsim cov hmoov putty zoo, cov qauv qauv yuav tsum tsim nyog, thiab cov additives hauv nws yuav tsum siv kom tsim nyog. Peb siv redispersible latex hmoov los txhim kho lub zog, yog li cas peb tuaj yeem ua kom lub zog no?

Ua ntej ntawm tag nrho cov, peb yuav tsum to taub dab tsi redispersible latex hmoov yog dab tsi thiab nws yog ua li cas. Nws lub luag haujlwm tseem ceeb yog txhawm rau txhim kho lub zog. Cov muaj pes tsawg leeg kuj yog ua los ntawm polymer emulsion thiab ces muaj ntau yam additives ntxiv. Nyob rau tib lub sijhawm, kev tiv thaiv colloid thiab anti-caking tus neeg sawv cev ntxiv. Cov polymer yog txau-qhuav los ua cov hmoov dawb-ntws uas yog redispersible hauv dej. Peb tsuas yog siv los tsim cov hmoov putty thiab ntxiv rau cov hmoov qhuav mortar.

Thaum lub sij hawm tsim cov txheej txheem, cov hmoov latex redispersible tuaj yeem hloov pauv thiab rov emulsified, thiab tom qab ntawd lub hauv paus txheej tsis tu ncua absorbs dawb noo noo nyob rau hauv cov voids ntawm mortar thiab noj tsis tu ncua, thiab muaj zog alkaline ib puag ncig muab los ntawm cov cement ua rau cov latex. particles qhuav thiab tsim nyob rau hauv lub mortar. Ib zaj duab xis tas li insoluble hauv dej tsim los ntawm fusion ntawm monodisperse hais nyob rau hauv ib qho emulsion rau hauv homogeneous loj.

Tom qab dispersion, lub redispersible latex hmoov yog ib tug tshuaj tsuag-qhuav dispersion, uas yog ntxiv rau dej los tsim ib tug ruaj khov dispersion nrog tib yam khoom raws li tus thawj dispersion. Txawm li cas los xij, muaj qee yam xwm txheej rau kev tsim cov hmoov latex no. Nws yuav tsum tau ua nyob rau hauv qhov kub thiab txias. Tag nrho cov dispersions tuaj yeem hloov mus rau hauv redispersible latex hmoov.

Redispersible latex hmoov kuj tuaj yeem txhim kho kev tsim kho kev ua haujlwm, thiab nws tseem yog lub luag haujlwm tseem ceeb heev los ua cov hmoov putty thiab qhuav mortar peb tsim tau zoo dua hauv kev tsim kho. Tom qab qhov sib ntxiv, qhov khawb kuj thiab flexural lub zog ntawm cov tshuaj khib kuj tau txhim kho, uas tuaj yeem ua rau cov tshuaj khib nyiab ntau dua thiab kho tsis tau.
