Yuav ua li cas xaiv redispersible polymer hmoov?

Yuav ua li cas xaiv redispersible polymer hmoov?

Tsis muaj txoj hauv kev zoo dua li muab cov khoom tso rau hauv qhov kev sim.

Kev xaiv cov khoom tsim nyog redispersible latex hmoov yuav tsum xav txog cov hauv qab no:

1. Cov iav hloov pauv kub ntawm cov hmoov polymer redispersible.

Cov iav hloov pauv kub yog tias cov polymer nthuav tawm elasticity; Hauv qab no qhov kub thiab txias, lub polymer nthuav tawm brittleness. Lub iav hloov kub ntawm cov hmoov latex dav dav yog -15±5℃, thiab cov hmoov latex ntawm cov tuam txhab lag luam ib txwm tsis muaj qhov ntsuas no. Teeb meem. Lub iav hloov pauv qhov kub thiab txias yog qhov taw qhia tseem ceeb ntawm lub cev lub cev ntawm cov hmoov latex redispersible. Rau ib yam khoom tshwj xeeb, kev xaiv tsim nyog ntawm cov iav hloov pauv kub ntawm redispersible latex hmoov yog qhov tsim nyog los txhim kho qhov yooj yim ntawm cov khoom thiab tsis txhob muaj teeb meem xws li tawg.

2. Yam tsawg kawg nkaus zaj duab xis tsim kub

Tom qab redispersible latex hmoov yog tov nrog dej thiab rov emulsified, nws muaj cov khoom zoo sib xws rau thawj emulsion, uas yog, ib zaj duab xis yuav raug tsim tom qab cov dej evaporates. Cov yeeb yaj kiab no muaj qhov yooj yim thiab zoo adhesion rau ntau yam substrates. Qhov sib txawv Qhov tsawg kawg nkaus zaj duab xis-tsim kub ntawm cov hmoov latex uas tsim los ntawm cov chaw tsim khoom yuav txawv me ntsis. Qhov Performance index ntawm qee cov tuam ntxhab yog 0°C, thiab qhov Performance index ntawm ib co manufacturers yog 5°C. Ntev npaum li qhov kub ntawm zaj duab xis-forming ntawm latex hmoov nrog zoo zoo nyob nruab nrab ntawm 0 thiab 5°C nruab nrab.

3. Redissolvability.

Inferior redispersible latex hmoov yog ib feem los yog tsis yooj yim soluble 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 yog kho rau hauv ib tuj roj hmab hmoov.

Yog tias 2% cov ntsiab lus dej raug suav, ces 1.7 tons ntawm emulsion yog siv los ua ib tuj roj hmab hmoov, ntxiv rau 10% ntawm cov hmoov 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 covredispersible polymer hmoov, qee cov neeg siv khoom tsuas yog yaj cov hmoov latex hauv dej thiab nplawm ntawm tes los kuaj nws, thiab pom tias tsis muaj qhov nplaum, xav tias nws tsis yog cov hmoov latex tiag tiag.

Nyob rau hauv qhov tseeb, redispersible latex hmoov nws tus kheej tsis nplaum, nws yog ib tug hmoov tsim tom qab lub polymer emulsion yog tshuaj tsuag-qhuav.

Thaum cov hmoov latex redispersible tov nrog dej thiab rov emulsified, nws muaj tib yam khoom raws li tus thawj emulsion, uas yog, zaj duab xis tsim tom qab cov dej evaporates muaj siab yooj thiab muaj zoo adhesion rau ntau yam substrates.

Nws tuaj yeem txhim kho cov dej tuav ntawm cov khoom, tiv thaiv cov cement mortar los ntawm hardening sai heev, qhuav thiab tawg; nce lub plasticity ntawm mortar thiab txhim kho kev tsim kho kev ua haujlwm. Dispersion, zaj duab xis-forming zog, yooj (suav nrog rub-tawm kev sim, seb tus thawj lub zog puas tsim nyog) feem ntau, qhov kev xeem yuav muaj tom qab 10 hnub
