Hmoov Polymer Redispersible (RDP) yog ib hom polymer siv rau ntau yam kev siv. RDP yog ib hom hmoov uas yaj tau hauv dej ua los ntawm ntau yam polymers, suav nrog vinyl acetate, vinyl acetate ethylene, thiab acrylic resins. Cov hmoov no sib xyaw nrog dej thiab lwm yam khoom ntxiv los ua ib qho slurry, uas tom qab ntawd siv rau ntau yam substrates. Muaj ntau hom RDP, txhua hom muaj nws cov yam ntxwv thiab kev siv tshwj xeeb. Hauv tsab xov xwm no, peb yuav tshawb nrhiav qee hom RDP uas siv ntau tshaj plaws thiab lawv cov kev siv.
1. Vinyl acetate redispersible polymer
Cov polymers vinyl acetate redispersible yog hom RDP feem ntau. Lawv yog ua los ntawm vinyl acetate thiab vinyl acetate ethylene copolymer. Cov polymer me me raug dispersed hauv dej thiab tuaj yeem rov ua dua tshiab rau hauv cov kua. Hom RDP no muaj ntau yam kev siv suav nrog cov mortars sib tov qhuav, cov khoom cement thiab cov tshuaj sib xyaw ua ke. Lawv muab kev nplaum zoo heev, kev ywj pheej thiab kev ruaj khov.
2. Acrylic redispersible polymer
Cov polymers acrylic redispersible yog ua los ntawm acrylic lossis methacrylic copolymers. Lawv lub zog tshwj xeeb thiab kev tiv taus kev sib txhuam ua rau lawv zoo tagnrho rau cov ntawv thov uas qhov ruaj khov yog qhov tseem ceeb. Lawv siv rau hauv cov nplaum pobzeb, cov khoom siv rwb thaiv tsev sab nraud thiab cov txheej txheem tiav (EIFS), thiab cov tshuaj kho.
3. Ethylene-vinyl acetate redispersible polymer
Cov polymers Ethylene-vinyl acetate redispersible yog ua los ntawm ethylene-vinyl acetate copolymers. Lawv siv rau ntau yam kev siv xws li cov cement mortars, grouts thiab cov nplaum pobzeb. Lawv muaj kev ywj pheej zoo heev thiab kev nplaum rau kev siv hauv cov chaw muaj kev ntxhov siab siab.
4. Styrene-butadiene redispersible polymer
Cov polymers styrene-butadiene redispersible yog ua los ntawm styrene-butadiene copolymers. Lawv siv rau ntau yam kev siv xws li cov tshuaj kho pob zeb, cov nplaum pobzeb thiab cov grouts. Lawv muaj cov dej tsis kam thiab cov khoom nplaum zoo heev.
5. Cov hmoov polymer uas rov ua kom emulsifiable
Cov hmoov polymer uas rov ua kom emulsifiable yog RDP uas tsim los kom rov ua kom emulsified hauv dej tom qab ziab. Nws siv rau ntau daim ntawv thov uas cov khoom raug dej lossis noo noo tom qab siv. Cov no suav nrog cov nplaum rau pobzeb, grout, thiab caulk. Lawv muaj kev tiv thaiv dej zoo heev thiab yooj ywm.
6. Hydrophobic redispersible polymer hmoov
Cov hmoov polymer hydrophobic redispersible uas tsim los ua kom cov khoom siv cement tsis kam dej ntau ntxiv. Feem ntau nws yog siv rau hauv cov ntawv thov uas cov khoom yuav kov dej, xws li Exterior Insulation and Finishing Systems (EIFS), cov nplaum rau cov vuas pas dej ua ke thiab cov tshuaj kho pob zeb. Nws muaj kev tiv thaiv dej zoo heev thiab ruaj khov.
Cov hmoov latex uas tawg tau dua yog ib yam khoom siv tau ntau yam uas siv tau rau ntau yam kev siv. Muaj ntau hom RDP, txhua hom muaj nws cov yam ntxwv thiab kev siv tshwj xeeb. Lawv qhov kev nplaum zoo heev, kev ywj pheej thiab kev ruaj khov ua rau lawv zoo tagnrho rau kev siv rau ntau yam khoom. Thaum siv kom raug, lawv tuaj yeem pab txhim kho qhov zoo thiab lub neej ntev ntawm ntau yam khoom siv hauv tsev.
