Redispersible polymer hmoovrfeem ntau yog siv rau sab nrauv phab ntsa ntawm lub tsev nrog cov hmoov putty los yog lwm cov cement sib tov, feem ntau yog cov cement thiab lwm cov khoom sib tov rau sab hauv, thiab cov hmoov latex tov nrog putty hmoov los pleev xim rau sab nrauv, nws muab rau tib neeg ib yam ntawm nws muaj mos mos. kev xav, thiab tuaj yeem txhim kho lub zog adsorption ntawm mortar, kom lub neej kev pab cuam ntawm phab ntsa sab nrauv yog ntev dua.
Nws txoj haujlwm yog thawj zaug pom nyob rau hauv kev txhim kho cov adhesion ntawm lub mortar, vim hais tias cov hmoov latex yuav nkag mus rau hauv cov cement thiab ua kom nws puv ntawm cov dej noo, yog li ntawm chav kawm adhesion muaj peev xwm zoo dua.Ntau zaus peb muaj mob taub hau vim cov cement tsis tuaj yeem nrog ntoo thiab fiber ntau thiab lwm yam khoom siv raw, tab sis nrog rau redispersible polymer hmoov, peb tsis tas yuav txhawj txog txhua yam.Peb txhua tus paub tias kev khoov ntawm cov cement tsis zoo tom qab hardening, thiab ntxiv cov hmoov latex yuav txhim kho nws cov tawv nqaij, kom nws tuaj yeem tiv taus siab dua deformation.Txawm tias lub microstructure ntawm cov cement pob zeb yuav hloov los ntawm nws.Nws yuav thaiv cov dej nqus ntawm cov qauv sab hauv thiab tiv thaiv cov dej los ntawm permeating tawm.Tom qab ntawd lub peev xwm los tiv thaiv permeability ntawm sab nrauv phab ntsa kuj tau txhim kho.Tsis tas yuav txhawj xeeb txog cov dej ntws hauv tsev thaum los nag.Up.
Redispersible polymer hmoovyog ntxiv rau cov cement, kom cov cement zoo thiab hmoov av sib xyaw ua ke, yog li lub peev xwm thauj khoom ntawm cov mortar tau zoo dua qub, thiab hnav tsis kam ua kom muaj zog.Rau sab nrauv phab ntsa, Yuav tsis yooj yim nkag dej, tawg tawg, deformation yog tus qauv tsim nyog.Raws li ib txwm muaj, cov phab ntsa sab nrauv yooj yim feem ntau muaj lub neej ua haujlwm luv luv, thiab nws yooj yim tawg tom qab ob peb xyoos.Yog li ntawd, cov xim latex feem ntau ntxiv rau hauv cov txheej txheem tsim kho nyob rau xyoo tas los no txhawm rau ua kom nws lub neej ua haujlwm thiab ua kom cov neeg nyob hauv lub neej.Kev nyab xeeb ntawm tus kheej thiab khoom ntiag tug.
Yog li, qhov twg tuaj yeemredispersible polymer hmoovsiv?Redispersible polymer hmoovtuaj yeem siv rau hauv cov chaw hauv qab no: cement-based, gypsum-based, bonding mortar, plastering mortar, waterproof mortar, anti-cracking mortar, decorative mortar, cement mortar, plastering mortar, masonry mortar, grout concrete repair and repair mortar, batching mortar, pem teb mortar (tus kheej-leveling cement mortar rau hauv qab txheej, txheej txheej, thiab lwm yam), pob zeb qhuav, txheej txheej hauv av, pobzeb sib txuas, kev tsim cov nplaum, tus neeg sawv cev sib koom ua ke, kev sib koom ua ke plaster, stucco Gypsum, sab hauv phab ntsa putty, sab nrauv phab ntsa putty, diatom av nkos, waterproof txheej, ntau yam txheej,redispersible polymer hmoovtuaj yeem siv ua plasticizers, tougheners, thiab
thickeners rau inorganic hydraulic cov ntaub ntawv xws li cement thiab gypsum, Binder, film-forming tus neeg saib xyuas, waterproofing agent.
Redispersible polymer hmoovrmuaj cov yam ntxwv hauv qab no:
1. Cov khoom siv redispersible latex hmoov yog cov dej-soluble redispersible hmoov, copolymer ntawm ethylene thiab vinyl acetate, nrog polyvinyl cawv raws li kev tiv thaiv colloid.
2. VAE redispersible latex hmoov muaj zaj duab xis-forming zog.50% aqueous tov yuav tsim ib qho emulsion, uas yuav tsim ib zaj duab xis zoo li yas tom qab muab tso rau hauv iav rau 24 teev.
3. Cov yeeb yaj kiab tsim muaj qee yam yooj yim thiab dej tsis kam.Muaj peev xwm ncav cuag lub teb chaws tus qauv.
4. Lub redispersible latex hmoov muaj kev ua tau zoo: nws muaj peev xwm sib txuas siab, kev ua tau zoo thiab kev ua haujlwm tsis zoo, kev sib txuas zoo zog, muab cov tshuaj khib nyiab zoo heev alkali tsis kam, thiab tuaj yeem txhim kho qhov adhesion thiab flexural zog ntawm mortar, ntxiv rau plasticity , hnav tsis kam thiab ua haujlwm tau zoo, nws muaj zog yoog raws hauv cov tshuaj tiv thaiv tawg.
