Redispersible latex hmoov yog cov hmoov tau los ntawm cov tshuaj tsuag kom qhuav cov polymer emulsion thiab tom qab ntawd ntxiv cov tshuaj hloov pauv, uas tuaj yeem hloov pauv los ua ib qho emulsion thaum nws ntsib dej.Redispersible latex hmoov feem ntau yog siv los ua ib qho tshuaj ntxiv rau cov khoom sib xyaw qhuav, uas muaj lub luag haujlwm ntawm kev txhim kho kev ua haujlwm ntawm mortar, txhim kho fluidity, txhim kho cohesion, thiab ua kom muaj zog sib txuas.Nws yog ib yam tshiab ntawm ib puag ncig tus phooj ywg khoom.Tam sim no, cov hmoov latex yuav tsum tau ntxiv rau cov pobzeb sib txuas, sab nrauv phab ntsa rwb thaiv tsev, nws tus kheej-leveling, putty hmoov, thiab lwm yam.
Lub polymer emulsion siv nyob rau hauv redispersible latex hmoov yog tsuas yog polymer emulsion tsim los ntawm kev ntxiv ib los yog ob monomers rau yas acetate raws li ib tug monomer nyob rau hauv Tuam Tshoj.Tam sim no, vinyl acetate-ethylene copolymer emulsion, vinyl acetate - Feem ntau ethylene tertiary carbonate copolymer emulsion, additives yuav muab ntxiv rau cov hmoov latex uas tsim los txhim kho kev tiv thaiv kev tiv thaiv thiab rov ua dua tshiab.Txawm li cas los xij, vim yog cov qauv ntawm vinyl acetate, nws cov thawj lub zog thiab dej kho lub zog tsis zoo nyob rau hauv cov nqe lus ntawm adhesion rau rwb thaiv tsev boards thiab cement substrates.
Acrylic emulsion muaj cov dej tsis zoo thiab siv dav hauv cov khoom siv hauv tsev, tab sis nws cov txheej txheem ziab thiab hmoov txau yog qhov tsis paub qab hau, thiab nws qhov kev faib ua feem hauv cov hmoov av redispersible emulsion yog me me, thiab adhesion ntawm acrylic emulsion yog pluag, thiab nws yog nplaum rau mortar.Kev txhim kho tsis txaus hauv kev sib txuas lub zog txwv kev siv cov acrylic emulsions.
Lub hom phiaj ntawm cov tshiab acrylic latex hmoov thiab cov txheej txheem kev npaj ntawm no yog kom tau cov khoom latex hmoov nrog siab cohesive zog thiab zoo adhesion.
1. Lub redispersible latex hmoov muaj cohesiveness zoo heev, uas tuaj yeem txhim kho cov cohesion ntawm lub tsev mortar, txhim kho qhov adhesion ntawm mortar thiab cov khoom siv hauv paus, thiab txhim kho kev ua haujlwm.Nws yog tsim rau cov khoom siv hauv tsev thiab mortars uas yuav tsum tau muaj zog sib txuas.teb, kev lag luam zeem muag yog dav.
2. Nyob rau hauv lub formulation system ntawm redispersible latex hmoov, ntau yam polymer emulsions raws li acrylic emulsion raug xaiv thiab sib tov raws li qhov tsim nyog piv, uas muaj peev xwm muab tag nrho cov kev ua si rau lawv qhov zoo, txhim kho kev ua tau zoo ntawm cov hmoov latex, thiab nthuav dav ntawm cov hmoov latex.Scope ntawm daim ntawv thov.
3. Nyob rau hauv kev npaj ntawm redispersible latex hmoov, cov tshuaj tsuag kua yog ncaj qha rhuab los ntawm cov cua sov hauv internet, uas txhim kho lub redispersibility ntawm cov latex hmoov.
4. Nyob rau hauv cov qauv txheej txheem ntawm redispersible latex hmoov, ob hom mixs ntawm calcium carbonate, talcum hmoov, kaolin thiab silicon dioxide raug xaiv los ua anti-caking agents nrog ib tug loj ratio ntawm 1: 1-2, thiaj li hais tias latex hmoov. particles Lub wrapping yog ntau yam sib xws thiab cov cuab yeej los tiv thaiv cov hmoov latex zoo dua.
5. Nyob rau hauv lub formulation system ntawm redispersible latex hmoov, ib los yog ib tug sib tov ntawm silicone defoamer thiab cov ntxhia roj defoamer yog xaiv raws li lub defoamer ntawm ib tug loj ratio ntawm 1: 1, uas txhim kho cov zaj duab xis-forming khoom ntawm latex hmoov. txhim kho qhov kev sib txuas ntawm mortar.
6. Cov txheej txheem kev npaj ntawm redispersible latex hmoov yog yooj yim thiab yooj yim kom paub industrialization.
