(1) .properties ntawm redispersible looj hmoov:

1.chemical composition:

Redispersible looj cov hmoov feem ntau yog tsim cov hluavtaws polymers xws li vinyl acetate ethylene (Vinyl acetate (Vinyl acetate (Vinyl acetate (Vinylees-Vinyl Chloride (ELC).
Cov polymers no tau muab cov nplaum, cohesive, thiab ua yeeb yaj kiab-ua yeeb yam rau cov hmoov.

2.particle loj thiab morphology:

Lub particle loj ntawm redispersible looj hmoov feem ntau yog li 1 txog 100 micrometers.
Morphologically, cov lus piav qhia ib hom spherical lossis tsis xwm yeem, nyob ntawm kev tsim khoom.
Recispersibility:

Redispersible looj cov peev xwm tuaj yeem ua kom muaj peev xwm tawg hauv dej los ua cov khoom ruaj khov, mimicking cov khoom ntawm cov thawj cov kev faib tawm.
Cov cuab yeej no yog qhov tseem ceeb rau kev siv uas yuav tsum tau muab cov ntawv sau ua kua los ua kua, xws li hauv kev tsim cov khoom lag luam thiab cov nplaum.

3.film tsim:

Thaum cov dej rov qab, cov hmoov av zoo li cov hmoov txhuv duab ruaj khov nrog cov nplaum zoo heev rau ntau cov substrates, nrog rau cov pob zeb, thiab yas.
Zaj duab xis muab kev tiv thaiv tiv thaiv ya raws, UV hluav taws xob, thiab kev ntxhov siab.

(2) .applications ntawm redispersible looj hmoov:

1.Txoj kev lag luam:

RDP muaj ntau yam siv nyob rau hauv cov khoom tso cai xas xws li cov khoom sib xyaw ua ke, thiab lub tshuab rwb thaiv tsev sab nraud (EIFS).
Nws txhim kho adhesion, yooj yim, thiab cov dej tsis kam ntawm mortars, txhim kho lub durability thiab kev ua tau zoo ntawm cov khoom siv kev tsim kho.

2.paints thiab txheej:

Redispersible LasX hmoov pabcuam ua cov xim thau cov xim thiab pleev xim, ua rau cov yeeb yaj kiab zoo heev thiab cov nplaum ua kom pom tseeb.
Nws txhim kho lub durability, txhuam kom tiv thaiv, thiab huab cua cov xim tha xim, ua rau lawv haum rau cov ntawv thov sab hauv thiab sab nrauv.

3.Adhates thiab laserants:

RDP yog koom rau hauv cov nplaum thiab cov qauv freatants los txhim kho Tack, Cohesion, thiab yooj.
Nws ua rau kev txhim kho cov dej-cov nplaum nplaum uas muaj txiaj ntsig zoo thiab cov nplaum kom muaj ntau yam ntoo, suav nrog cov ntoo, thiab cov hlau.

4.Thmaceuticals:

Hauv cov tshuaj ua yeeb yam, cov hmoov liab rasxersx tau siv los ua phau ntawv tsim khoom hauv ntsiav tshuaj.
Nws pab txhawb cov hmoov nplej ntawm hmoov rau hauv cov ntsiav tshuaj thaum muab cov khoom siv tshuab zog thiab cov khoom siv tsis sib haum xeeb.

(3) .Mmufacturing cov txheej txheem ntawm redispersible looj hmoov:

1.emulsion polymerization:

Thawj txoj kev rau kev tsim cov liab rasx hmoov yuav cuam tshuam cov monomsion ntawm monomers xws li vinylene ntawm lub xub ntiag ntawm emulsifiers thiab stabilizers.
Cov tshuaj tiv thaiv polymerization tau tshwm sim hauv cov xov xwm aqueous, ua rau muaj kev tsim ntawm cov polymer partic ua txwv hauv dej.

2.Spray ziab:

Tom qab emulsion polascerization, cov yas dispersion yog muaj cov hmoov thiab tshuaj tsuag-ziab kom tau txais cov hmoov zoo.
Nyob rau hauv cov tshuaj tsuag cov txheej txheem, cov yas yog atomized rau cov tee dej thiab qhia rau hauv cov dej kub, qhov twg dej evaporates sai sai, yielding khov kho cov khoom polymer.

3.Pos-Kho:

Cov kauj ruam tom qab kho mob xws li kev hloov kho saum npoo, ziab, thiab cov khoom siv me me yuav ua haujlwm rau cov hmoov av ntawm redispersible looj ntaub ntawv tshwj xeeb.
Kev hloov kho cov txheej txheem saum npoo xws li kev sib txuam ntawm cov kev ua kom sib ntxiv lossis cov neeg sawv cev ntawm cov hmoov kom zoo.

Redispersible looj lub luag haujlwm tseem ceeb hauv ntau kev lag luam vim nws cov khoom ntiag tug thiab versatility. Los ntawm kev txhim kho cov ntaub ntawv kev tsim kho kom txhim kho lub zog ntawm cov xim tha xim thiab txheej, RDP muaj ntau cov ntawv thov. Nkag siab txog cov khoom siv, kev siv, thiab kev tsim cov txheej txheem ntawm redispersible yas hmoov yog qhov tseem ceeb rau kev ua haujlwm tshiab nyob rau cov khoom lag luam tshiab thoob plaws ntau txoj haujlwm.
