Redispersible Polymer Powder (RDP) yog ib qho polymer siv ntau yam kev siv. RDP yog cov dej-soluble hmoov ua los ntawm ntau yam polymers, xws li yas acetate, yas acetate ethylene, thiab acrylic resins. Cov hmoov yog tov nrog dej thiab lwm yam additives los ua ib tug slurry, uas yog ces siv rau txawv substrates. Muaj ntau ntau hom RDP, txhua tus muaj nws tus kheej cov khoom thiab siv. Hauv tsab xov xwm no, peb yuav tshawb txog qee hom RDP feem ntau thiab lawv cov ntawv thov.
1. Vinyl acetate redispersible polymer
Vinyl acetate redispersible polymers yog hom RDP tshaj plaws. Lawv yog tsim los ntawm vinyl acetate thiab vinyl acetate ethylene copolymer. Cov ntaub ntawv polymer yog dispersed hauv dej thiab tuaj yeem rov ua dua rau hauv lub xeev ua kua. Hom RDP no muaj ntau yam kev siv xws li cov khoom sib xyaw qhuav, cov khoom cement thiab cov khoom sib xyaw ua ke. Lawv muab cov adhesion zoo, yooj thiab durability.
2. Acrylic redispersible polymer
Acrylic redispersible polymers yog tsim los ntawm acrylic los yog methacrylic copolymer. Lawv lub zog tshwj xeeb thiab kev puas tsuaj ua rau lawv zoo tagnrho rau cov ntawv thov uas muaj kev ruaj khov yog qhov tseem ceeb. Lawv siv rau hauv pobzeb nplaum, rwb thaiv tsev sab nrauv thiab ua tiav tshuab (EIFS), thiab kho mortars.
3. Ethylene-vinyl acetate redispersible polymer
Ethylene-vinyl acetate redispersible polymers yog tsim los ntawm ethylene-vinyl acetate copolymer. Lawv tau siv ntau yam kev siv xws li cov cement mortars, grouts thiab pobzeb adhesives. Lawv muaj qhov yooj yooj yim thiab adhesion rau siv nyob rau hauv ib puag ncig kev ntxhov siab.
4. Styrene-butadiene redispersible polymer
Styrene-butadiene redispersible polymers yog tsim los ntawm styrene-butadiene copolymer. Lawv yog siv nyob rau hauv ntau yam kev siv xws li pob zeb kho mortars, pobzeb adhesives thiab grouts. Lawv muaj cov dej tsis zoo thiab cov nplaum nplaum.
5. Re-emulsifiable polymer hmoov
Re-emulsifiable polymer hmoov yog RDP tsim los rov emulsified hauv dej tom qab ziab. Nws yog siv nyob rau hauv ntau daim ntawv thov qhov twg cov khoom raug dej los yog ya raws tom qab siv. Cov no suav nrog cov nplais nplaum, grout, thiab caulk. Lawv muaj kev tiv thaiv dej zoo heev thiab yoog raws.
6. Hydrophobic redispersible polymer hmoov
Hydrophobic redispersible polymer hmoov tsim los ua kom cov dej tsis kam ntawm cov khoom siv cement. Nws feem ntau yog siv rau hauv cov ntawv thov uas cov khoom yuav tuaj rau hauv kev sib cuag nrog dej, xws li Sab nrauv rwb thaiv tsev thiab Finishing Systems (EIFS), pas dej da dej pobzeb adhesives thiab pob zeb kho mortars. Nws muaj dej tsis kam thiab durability.
Redispersible latex hmoov yog cov khoom siv ntau yam uas tuaj yeem siv rau hauv ntau daim ntawv thov. Muaj ntau ntau hom RDP, txhua tus muaj nws tus kheej cov khoom thiab siv. Lawv zoo heev adhesion, yooj thiab durability ua rau lawv zoo tagnrho rau siv nyob rau hauv ntau yam khoom. Thaum siv kom raug, lawv tuaj yeem pab txhim kho qhov zoo thiab lub neej ntev ntawm ntau lub tsev khoom.
