CovRDP hmoovyog dej-solubleredispersible hmoov, uas yog copolymer ntawm ethylene thiab vinyl acetate, thiab siv polyvinyl cawv raws li kev tiv thaiv colloid.Vim muaj kev sib raug zoo siab thiab cov khoom tshwj xeeb ntawm redispersible latex hmoov, xws li dej tsis kam, ua haujlwm, thiab thermal rwb thaiv tsev, lawv daim ntawv thov ntau yam dav heev.Redispersible latex hmoov yog tsuas yog siv nyob rau hauv ntau yam qhuav mix mortars xws li putty hmoov rau sab hauv thiab sab nrauv phab ntsa, ceramic pobzeb tsev neeg tus neeg saib xyuas, ceramic pobzeb taw tes tus neeg saib xyuas, qhuav hmoov interface tus neeg saib xyuas, sab nrauv phab ntsa rwb thaiv tsev mortar, nws tus kheej leveling mortar, kho mortar, hniav mortar. , waterproof mortar, thiab lwm yam. Redispersible latex hmoov yog ntsuab, ib puag ncig tus phooj ywg, txuag hluav taws xob, zoo thiab ntau yam hmoov tsev khoom, thiab yog ib qho tseem ceeb functional additive rau qhuav mix mortar.Nws tuaj yeem txhim kho kev ua haujlwm ntawm mortar, ua kom nws lub zog, txhim khu kev sib txuas ntawm cov mortar thiab ntau yam substrates, txhim khu kev yooj yim thiab hloov pauv, compressive zog, flexural zog, hnav tsis kam, toughness, adhesion thiab dej tuav peev xwm, thiab constructability ntawm mortar.Tsis tas li ntawd, latex hmoov nrog hydrophobicity tuaj yeem ua rau cov mortar muaj cov khoom tsis zoo.
Lub luag haujlwm ntawmredispersible latex hmoov:
1. CovEVA copolymertsim ib zaj duab xis tom qab dispersion thiab ua hauj lwm raws li cov nplaum thib ob los txhim kho nws lub zog;
2. Cov kev tiv thaiv colloid yog absorbed los ntawm lub mortar system (nws yuav tsis puas los ntawm dej tom qab tsim zaj duab xis, los yog "secondary dispersion";
3. Cov zaj duab xis-forming polymer resin yog muab faib ua cov khoom siv txhawb nqa thoob plaws tag nrho cov mortar system, yog li ua kom cov cohesion ntawm mortar;Redispersible emulsion hmoov yog ib hom hmoov nplaum ua los ntawm cov tshuaj pleev tshwj xeeb (siab polymer) tom qab cov tshuaj tsuag kom qhuav.Tom qab sib cuag nrog dej, cov hmoov no tuaj yeem tawg sai sai rau daim ntawv pleev xim, thiab muaj cov khoom zoo ib yam li cov tshuaj pleev xim thawj zaug, uas yog, cov dej tuaj yeem tsim cov yeeb yaj kiab tom qab evaporation.Cov yeeb yaj kiab no muaj qhov hloov tau yooj yim, huab cua tsis kam thiab siab adhesion rau ntau yam substrates.
Kev ua haujlwm thiab kev siv ntawm Redispersible Latex Powder
Redispersible emulsion hmoov yog ib hom hmoov nplaum ua los ntawm cov tshuaj pleev tshwj xeeb (siab polymer) tom qab cov tshuaj tsuag kom qhuav.Tom qab sib cuag nrog dej, cov hmoov no tuaj yeem tawg sai sai rau daim ntawv pleev xim, thiab muaj cov khoom zoo ib yam li cov tshuaj pleev xim thawj zaug, uas yog, cov dej tuaj yeem tsim cov yeeb yaj kiab tom qab evaporation.Cov yeeb yaj kiab no muaj qhov hloov tau yooj yim, huab cua tsis kam thiab siab adhesion rau ntau yam substrates.
Siab zog RDPyog ntsuab, ib puag ncig tus phooj ywg, txuag hluav taws xob, zoo thiab ntau yam hmoov tsev cov khoom, thiab yog ib qho tseem ceeb ua haujlwm additive rau qhuav mix mortar.Nws tuaj yeem txhim kho kev ua haujlwm ntawm mortar, ua kom nws lub zog, txhim khu kev sib txuas ntawm cov mortar thiab ntau yam substrates, txhim khu kev yooj yim thiab hloov pauv, compressive zog, flexural zog, hnav tsis kam, toughness, adhesion thiab dej tuav peev xwm, thiab constructability ntawm mortar.Tsis tas li ntawd, latex hmoov nrog hydrophobicity tuaj yeem ua rau cov mortar muaj cov khoom tsis zoo.
Redispersible latex hmoovFeem ntau yog siv nyob rau hauv ntau yam qhuav sib tov mortars xws li putty hmoov rau sab hauv thiab sab nrauv phab ntsa, ceramic pobzeb tsev neeg tus neeg saib xyuas, ceramic pobzeb taw tes tus neeg saib xyuas, qhuav hmoov interface tus neeg saib xyuas, sab nrauv phab ntsa rwb thaiv tsev mortar, self leveling mortar, kho mortar, hniav mortar, waterproof mortar , lwm.
Scope ntawm kev siv
1. Sab nrauv phab ntsa rwb thaiv tsev thiab plastering mortar
2. Ceramic pobzeb taw qhia tus neeg sawv cev
3. Yooj yim putty rau sab nrauv phab ntsa
Cov khoom no yog ib tug mos mos latex hmoov uas yuav dispersed nyob rau hauv dej, txhim kho lub adhesion ntawm mortar thiab zoo tib yam kev pab txhawb nqa, kev txhim kho cov neeg kho tshuab cov khoom ntawm mortar, thiab txhim kho nws constructability.
