Redispersible latex hmoov, tseem hu ua redispersible polymer hmoov (RDP), yog ib tug polymer hmoov uas ua los ntawm cov tshuaj tsuag kom qhuav dej raws li latex.Nws yog feem ntau siv los ua ib qho ntxiv hauv ntau yam khoom siv hauv tsev, suav nrog tshuaj khib.Ntxiv cov hmoov latex redispersible rau mortars muaj ntau yam txiaj ntsig, suav nrog kev txhim kho adhesion, yoog raws, dej tsis kam thiab kev ua haujlwm tag nrho.
A. Cov yam ntxwv ntawm redispersible latex hmoov:
1.Polymer muaj pes tsawg leeg:
Redispersible latex hmoov feem ntau yog tsim los ntawm ntau yam polymers, xws li yas acetate-ethylene (VAE), vinyl acetate-ethylene carbonate (VeoVa), thiab lwm yam. Cov polymers no ua rau cov hmoov muaj peev xwm tawg mus rau hauv dej.
2. Particle loj:
Qhov loj me me ntawm redispersible latex hmoov yog qhov tseem ceeb rau nws cov dispersibility thiab kev ua tau zoo hauv ntau daim ntawv thov.Finely faib hais kom yooj yim dispersion nyob rau hauv dej los tsim emulsions ruaj khov.
3. Redispersibility:
Ib tug ntawm cov yam ntxwv tseem ceeb ntawm cov hmoov no yog nws redispersibility.Thaum sib tov nrog dej, nws tsim ib tug ruaj khov emulsion zoo ib yam li thawj latex, muab cov kev pab cuam ntawm kua latex nyob rau hauv hmoov daim ntawv.
B.Lub luag hauj lwm ntawm redispersible latex hmoov nyob rau hauv mortar:
1. Txhim kho adhesion:
Qhov sib ntxiv ntawm dispersible latex hmoov rau mortars txhim kho adhesion rau ntau yam substrates, xws li pob zeb, masonry thiab ceramic vuas.Qhov no txhim kho adhesion pab txhim kho tag nrho lub zog thiab durability ntawm mortar.
2. Ua kom yooj:
Mortars hloov nrog redispersible latex hmoov qhia tau yooj yim dua.Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas lub substrate yuav muaj kev txav me ntsis lossis thermal expansion thiab contraction.
3. Waterproof:
Redispersible latex hmoov muab cov mortar dej tsis kam.Qhov no yog qhov tseem ceeb hauv cov ntawv thov uas cov mortar raug dej lossis dej noo, xws li hauv cov ntawv thov sab nrauv lossis qhov chaw ntub dej.
4. Txo kev tawg:
Qhov yooj yim muab los ntawm redispersible latex hmoov pab txo qhov yuav tshwm sim ntawm mortar cracking.Qhov no tseem ceeb tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas cov kab nrib pleb tuaj yeem cuam tshuam cov qauv kev ncaj ncees.
5. Enhanced processability:
Cov mortars uas muaj redispersible latex hmoov feem ntau pom kev txhim kho kev ua haujlwm, ua rau lawv yooj yim dua los tuav thiab tsim kho.Qhov no tej zaum yuav muaj txiaj ntsig zoo thaum kev tsim kho.
6. Compatibility nrog lwm yam additives:
Redispersible latex hmoov yog sib xws nrog ntau yam ntawm lwm yam additives feem ntau siv nyob rau hauv mortar formulations.Qhov no versatility tso cai rau mortar kev ua tau zoo raws li cov kev xav tau ntawm qhov project.
C. Qhov zoo ntawm kev siv redispersible latex hmoov hauv mortar:
1. Versatility:
Redispersible latex hmoov yog dav siv thiab tuaj yeem siv ntau hom mortars, nrog rau nyias-teeb mortars, kho mortars, thiab mortars waterproof.
2. Txhim khu durability:
Modified mortars muaj ntau dua durability thiab tsim nyog rau kev thov cov ntaub ntawv uas lub neej ntev yog ib qho tseem ceeb.
3. Kev ua haujlwm ruaj khov:
Cov txheej txheem kev tsim khoom ntawm redispersible latex hmoov ua kom muaj kev ua haujlwm zoo ib yam, ua rau muaj txiaj ntsig zoo hauv kev siv tshuaj khib nyiab.
4. Tus nqi-zoo:
Thaum tus nqi pib ntawm redispersible latex hmoov yuav siab dua li cov tshuaj additives ib txwm muaj, qhov kev txhim kho nws cov khoom siv rau hauv cov mortar tuaj yeem ua rau kom txuag tau nyiaj mus sij hawm ntev los ntawm kev txo qhov xav tau kev kho thiab tu.
5. Kev xav txog ib puag ncig:
Dej-raws li dispersible latex hmoov yog ib puag ncig tus phooj ywg ntau dua li cov kuab tshuaj raws li kev xaiv.Lawv pab txhawb kev tsim kho kom ruaj khov.
Redispersible latex hmoov yog cov khoom muaj txiaj ntsig zoo hauv cov tshuaj mortar, muab ntau yam txiaj ntsig xws li txhim kho adhesion, yoog raws, dej tsis kam thiab txo qhov tawg.Nws versatility thiab compatibility nrog lwm yam additives ua rau nws yog thawj xaiv rau ntau yam kev tsim kho daim ntawv thov.Los ntawm kev txhim kho cov khoom ntawm mortar, dispersible latex hmoov pab txhim kho lub zuag qhia tag nrho durability thiab kev ua tau zoo ntawm lub tsev Cheebtsam, ua rau nws yog ib qho tseem ceeb cuab tam nyob rau hauv niaj hnub kev tsim kho kev xyaum.
