Cov txheej txheem tshauv qauv rau cov liab liab polymer hmoov

Cov hmoov tshauv los ntawm lub Hoobkas tsis tu ncua feem ntau yog 10 ± 2
Cov hmoov tshauv txheem txheem yog li ntawm 12%, thiab qhov zoo thiab tus nqi yog sib piv
Qee cov hmoov nplej hauv tsev tau ntau dua 30%, thiab txawm tias qee cov hmoov roj hmab muaj ntau npaum li 50% tshauv.
Tam sim no qhov zoo thiab tus nqi ntawm dispersible polymer hmoov ntawm kev ua lag luam yog tsis ncaj, sim xaiv
Cov ntsiab lus tshauv qis, tus nqi siab ua tau zoo thiab muaj kev ruaj khov zoo ntawm cov khoom.
Yuav ua li cas xaiv refispersible looj hmoov, feem ntau nws yog tiag tiag tsis yooj yim sua kom pib thaum ua cov mis,
Tsis muaj txoj hauv kev zoo dua li muab tso rau hauv cov khoom siv rau kev sim.
Cov kev xaiv ntawm haum dispersible polymer hmoov yuav tsum tau txiav txim siab los ntawm cov hauv qab no:
1. Lub iav hloov cua kub ntawm cov neeg tawgible hmoov nplej.
Lub iav hloov cua kub yog cov polymer uas ua rau pom cov qauv elasticity; Hauv qab no qhov kub thiab txias no, cov khoom pov thawj polymer ua rau brittleness.
Feem ntau, lub iav hloov cua kub ntawm cov hmoov yas yog -15 5 ℃.
Yeej tsis muaj teeb meem.
Lub iav hloov cua kub yog qhov ntsuas loj ntawm cov khoom ntawm cov khoom siv uas tsis sib xws, thiab cov khoom tshwj xeeb,
Cov kev xaiv tsim nyog ntawm lub khob hloov pauv ntawm redispersible polymer hmoov yog conducive kom tau txais cov khoom lag luam yoog kom haum thiab zam
tawg, thiab lwm yam.
2. Yam tsawg kawg zaj duab xis tsim cov kub
Tom qab cov refispersible thiab recispersible polymer hmoov yog sib xyaw nrog dej thiab re-emulsified, nws muaj cov khoom zoo sib xws rau thawj emulsion.
Ntawd yog, tom qab cov dej evaporates, ib zaj duab xis yuav tsim, uas tau muaj peev xwm hloov kho thiab zoo adhesion rau ntau hom substrates.
Qhov tsawg kawg nkaus zaj duab xis-ua cov yeeb yaj kiab ntawm cov hmoov yas ua los ntawm cov chaw tsim khoom sib txawv yuav muaj me ntsis sib txawv.
Qhov ntsuas ntawm qee cov tuam ntxhab yog 5 ℃, ntev npaum li cov hmoov yas nrog cov yeeb yaj kiab zoo muaj cov yeeb yaj kiab-ua cov yeeb yaj kiab ntawm 0 thiab 5 ℃.
3. Redissolvable cov yam ntxwv.
Cov hmoov av tsis txaus ntseeg Polymer yog ib nrab lossis nyuaj rau hauv dej txias lossis dej alkaline.
4. Nqe.
Cov ntsiab lus ntawm cov emulsion yog li 53%, uas txhais tau tias txog 1.9 tons ntawm emulsion solorify ua ib qho ntawm cov kua roj hmab hmoov.
Yog tias koj suav 2% cov ntsiab lus dej, uas yog 1.7 tons ua ib tuj roj roj roj hmoov, ntxiv rau 10% ntawm cov tshauv,
Nws yuav siv li 1.5 tons ntawm emulsion los ua ib qho tuj cov roj hmab hmoov. 5 aqueous daws ntawm cov hmoov yas
Txhawm rau kuaj cov viscosity ntawm redispersible looj hmoov, qee cov neeg siv khoom tsuas yaj tau cov hmoov looj roj hmab cov hmoov av.
Tom qab nplawm hauv dej, Kuv sim nws los ntawm txhais tes, thiab pom tias nws tsis nplaum, yog li kuv xav tias nws tsis yog cov hmoov zoo tiag.
Qhov tseeb, redispersible lig plaub hmoov nws tus kheej tsis nplaum, nws yog tsim los ntawm cov tshuaj pleev kom qhuav ntawm polsher emulsion
ntawm cov hmoov.
Thaum cov refispersible polymer hmoov yog sib xyaw nrog dej thiab re-emulsified, nws muaj cov tib yam li emulsion qub, uas yog, noo noo
Cov yeeb yaj kiab tsim tom qab evaporation yog yoog tau yooj yim thiab ua raws li zoo heev rau ntau yam nkaus.
Nws tseem tuaj yeem txhim kho cov dej tuav ntawm cov khoom siv thiab tiv thaiv cov xis qab zib los ntawm cov tawv tawv los ntawm qhov tawv nqaij tawv, kom qhuav thiab tawg sai sai;
Ua kom muaj zog ntxiv ntawm lub tshuaj khib thiab txhim kho kev ua haujlwm. Yog tias ib qho kev sim yuav tsum tau ua, nws yuav tsum yog
Ua lub tshuaj khib rov ua kom pom nws qhov dispersibility, zaj duab xis tsim, yoog raws (suav nrog rub tawm cov kev sim,
Seb lub zog qub yog tsim nyog) feem ntau, cov txiaj ntsig kev sim tuaj yeem tau txais tom qab 10 hnub
