Cov ntsiab lus tshauv los ntawm qhov tsis tu ncuaredispersible polymer hmoovHoobkas feem ntau yog 10 ± 2
Cov hmoov tshauv cov ntsiab lus yog nyob rau hauv 12%, thiab qhov zoo thiab tus nqi sib piv
Qee cov hmoov latex hauv tsev muaj ntau dua 30%, thiab txawm tias qee cov hmoov roj hmab muaj ntau li 50% tshauv.
Tam sim no qhov zoo thiab tus nqi ntawm dispersible polymer hmoov ntawm kev ua lag luam tsis sib xws, sim xaiv
Cov ntsiab lus tsis tshua muaj tshauv, tus nqi siab ua haujlwm thiab cov khoom siv ruaj khov.
Yuav ua li cas xaiv redispersible latex hmoov, feem ntau nws tsis yooj yim sua kom pib thaum ua cov mis,
Tsis muaj txoj hauv kev zoo dua li muab tso rau hauv cov khoom rau kev sim.
Kev xaiv ntawm cov khoom tsim nyog dispersible polymer hmoov yuav tsum tau txiav txim siab los ntawm cov hauv qab no:
1. Lub iav hloov pauv kub ntawm cov tshuaj dispersible polymer hmoov.
Cov iav hloov pauv kub yog cov polymer uas nthuav tawm elasticity;Hauv qab no qhov kub thiab txias, lub polymer nthuav tawm brittleness.
Feem ntau, cov iav hloov pauv kub ntawm latex hmoov yog -15 ± 5 ℃.
Yeej tsis muaj teeb meem.
Cov iav hloov pauv kub yog qhov ntsuas tseem ceeb ntawm lub cev cov khoom ntawm cov hmoov polymer dispersible, thiab rau cov khoom tshwj xeeb,
Tsim nyog xaiv cov iav hloov kub ntawm redispersible polymer hmoov yog qhov tsim nyog los txhim kho cov khoom yooj yim thiab zam.
tawg, etc.
2. Yam tsawg kawg nkaus zaj duab xis tsim kub
Tom qab redispersible thiab redispersible polymer hmoov yog tov nrog dej thiab re-emulsified, nws muaj cov khoom zoo sib xws rau thawj emulsion.
Ntawd yog, tom qab dej evaporates, ib zaj duab xis yuav raug tsim, uas muaj qhov yooj yim thiab zoo adhesion rau ntau yam substrates.
Qhov tsawg kawg nkaus zaj duab xis-tsim kub ntawm latex hmoov tsim los ntawm txawv manufacturers yuav txawv me ntsis.
Qhov Performance index ntawm qee cov tuam txhab yog 5 ℃, tsuav yog cov hmoov latex nrog cov khoom zoo muaj qhov kub thiab txias ntawm 0 txog 5 ℃.
3. Redissolvable zog.
Inferior dispersible polymer hmoov yog ib feem los yog nyuaj yaj nyob rau hauv dej txias los yog alkaline dej.
4. Nqe.
Cov ntsiab lus ntawm emulsion yog li 53%, uas txhais tau hais tias txog 1.9 tons ntawm emulsion solidify rau hauv ib tuj roj hmab hmoov.
Yog tias koj suav 2% cov ntsiab lus dej, uas yog 1.7 tons ntawm emulsion los ua ib tuj roj hmab hmoov, ntxiv rau 10% ntawm tshauv,
Nws yuav siv li 1.5 tons ntawm emulsion los tsim ib tuj roj hmab hmoov.5. Aqueous tov ntawm latex hmoov
Txhawm rau kuaj cov viscosity ntawm redispersible latex hmoov, qee cov neeg siv khoom tsuas yog yaj cov hmoov latex hauv
Tom qab nplawm hauv dej, kuv sim nws ntawm tes, thiab pom tias nws tsis nplaum, yog li kuv xav tias nws tsis yog cov hmoov latex tiag tiag.
Qhov tseeb, redispersible latex hmoov nws tus kheej tsis yog nplaum, nws yog tsim los ntawm cov tshuaj tsuag kom qhuav ntawm polymer emulsionntawm hmoov.
Thaum cov hmoov polymer redispersible tov nrog dej thiab rov emulsified, nws muaj tib yam khoom raws li tus thawj emulsion, uas yog, noo noo.
Cov yeeb yaj kiab tsim tom qab evaporation yog qhov hloov tau yooj yim thiab ua tau zoo heev rau ntau yam substrates.
Nws tseem tuaj yeem txhim kho cov dej tuav ntawm cov khoom siv thiab tiv thaiv cov cement mortar los ntawm hardening, ziab thiab tawg sai heev;
Ua kom cov plasticity ntawm cov mortar thiab txhim kho kev tsim kho kev ua haujlwm.Yog tias qhov kev sim yuav tsum tau ua, nws yuav tsum yog proportional
Ua lub mortar retest kom pom nws dispersibility, tsim zaj duab xis, yooj (suav nrog rub-tawm xeem,
Txawm hais tias lub zog qub tsim nyog) Feem ntau, cov txiaj ntsig kev sim tuaj yeem tau txais tom qab 10 hnub
