Redispersible polymer hmoov yog ib qho tseem ceeb additive siv nyob rau hauv cementitious los yog gypsum-raws li cov ntaub ntawv nyob rau hauv kev tsim kho kev lag luam. Cov hmoov yog tsim los ntawm tshuaj tsuag-qhuav ib qho polymer dispersion, uas tsim cov hmoov dawb-ntws uas tuaj yeem yooj yim tov nrog lwm cov khoom xyaw qhuav. Muaj ntau ntau hom redispersible polymer hmoov muaj, txhua tus muaj nws tus kheej cov khoom thiab cov yam ntxwv. Hauv seem no, peb yuav saib qee yam ntawm cov feem ntau hom redispersible polymer hmoov.

1. Vinyl acetate-ethylene (VAE) redispersible polymer hmoov

VAE redispersible polymer hmoov yog ib qho ntawm feem ntau siv hom redispersible polymer hmoov nyob rau hauv kev tsim kho kev lag luam. Nws yog tsim los ntawm polymerizing vinyl acetate thiab ethylene nyob rau hauv ib tug dej-raws li emulsion, uas yog ces tsuag-qhuav kom tsim ib tug dawb-flowing hmoov. VAE redispersible polymer hmoov yog lub npe hu rau nws zoo heev adhesion, yooj, thiab dej tsis kam, ua rau nws zoo tagnrho rau siv nyob rau hauv cov ntaub ntawv uas durability yog ib qho tseem ceeb, xws li pob zeb kho, pobzeb nplaum, thiab rwb thaiv tsev sab nrauv thiab tiav tshuab (EIFS).

2. Vinyl acetate-raws li redispersible polymer hmoov

Vinyl acetate-raws li redispersible polymer hmoov yog tsim los ntawm polymerizing vinyl acetate nyob rau hauv ib tug dej-raws li emulsion, uas yog ces tsuag-qhuav los tsim ib tug dawb-flowing hmoov. Qhov no hom ntawm redispersible polymer hmoov yog paub rau nws zoo heev adhesion, workability, thiab khov-thaw kuj, ua rau nws zoo tagnrho rau siv nyob rau hauv daim ntaub ntawv xws li plaster, stucco, thiab hniav coatings.

3. Acrylic-raws li redispersible polymer hmoov

Acrylic-raws li redispersible polymer hmoov yog tsim los ntawm polymerizing acrylic monomers nyob rau hauv ib tug dej-raws li emulsion, uas yog ces tsuag-qhuav los tsim ib tug dawb-flowing hmoov. Acrylic-based redispersible polymer hmoov yog paub txog nws cov dej zoo heev, adhesion, thiab yooj, ua rau nws zoo tagnrho rau siv hauv cov ntawv thov xws li grout, kho pob zeb, thiab pobzeb nplaum.

4. Styrene-butadiene-based (SBR) redispersible polymer hmoov

SBR redispersible polymer hmoov yog tsim los ntawm polymerizing styrene thiab butadiene nyob rau hauv ib tug dej-raws li emulsion, uas yog ces tsuag-qhuav los tsim ib tug dawb-flowing hmoov. SBR redispersible polymer hmoov yog paub rau nws zoo heev yooj, adhesion, thiab dej tsis kam, ua rau nws zoo tagnrho rau siv nyob rau hauv daim ntaub ntawv xws li mortar, grout, thiab pob zeb kho.

5. Ethylene-vinyl chloride (EVC) redispersible polymer hmoov

EVC redispersible polymer hmoov yog tsim los ntawm polymerizing ethylene thiab vinyl chloride nyob rau hauv ib tug dej-raws li emulsion, uas yog ces tsuag-qhuav los tsim ib tug dawb-flowing hmoov. EVC redispersible polymer hmoov yog paub txog nws cov dej tsis zoo, adhesion, thiab saj zawg zog, ua rau nws zoo tagnrho rau siv rau hauv daim ntaub ntawv xws li pobzeb nplaum, kho pob zeb, thiab EIFS.

6. Redispersible polymer hmoov nrog hloov cov hmoov txhuv nplej siab

Redispersible polymer hmoov nrog hloov cov hmoov txhuv nplej siab yog tsim los ntawm kev ntxiv cov hmoov txhuv nplej siab hloov mus rau cov dej-raws li emulsion ua ntej tshuaj tsuag-qhuav. Cov hmoov txhuv nplej siab hloov ua raws li cov khoom tawg, pab kom stabilize lub emulsion thiab txhim kho cov redispersibility ntawm cov hmoov. Qhov no hom ntawm redispersible polymer hmoov yog paub rau nws zoo heev adhesion, workability, thiab dej tsis kam, ua rau nws zoo tagnrho rau siv nyob rau hauv daim ntaub ntawv xws li mortar, grout, thiab plaster.

7. Redispersible polymer hmoov nrog cellulose ether

Redispersible polymer hmoov nrog cellulose ether yog tsim los ntawm kev ntxiv cellulose ether rau cov dej-raws li emulsion ua ntej tshuaj tsuag-qhuav. Lub cellulose ether ua raws li cov thickener, txhim kho kev ua haujlwm ntawm cov hmoov thiab txo cov dej xav tau hauv kev sib tov. Qhov no hom ntawm redispersible polymer hmoov yog paub rau nws zoo heev adhesion, workability, thiab dej tuav, ua rau nws zoo tagnrho rau siv nyob rau hauv daim ntawv thov xws li pobzeb nplaum, grout, thiab cementitious waterproofing membranes.
