Redispersible Polymer Powder (RDP) polymer ne da ake amfani dashi a aikace-aikace iri-iri. RDP foda ne mai narkewa da ruwa wanda aka yi daga nau'ikan polymers, gami da vinyl acetate, vinyl acetate ethylene, da resin acrylic. Ana hada foda da ruwa da sauran abubuwan da za a yi amfani da su don samar da slurry, sannan a shafa a kan wasu abubuwa daban-daban. Akwai nau'ikan RDP da yawa, kowanne yana da kaddarorinsa na musamman da amfaninsa. A cikin wannan labarin, za mu bincika wasu mafi yawan nau'ikan RDP da aikace-aikacen su.
1. Vinyl acetate redispersible polymer
Vinyl acetate redispersible polymers sune mafi yawan nau'in RDP. An yi su daga vinyl acetate da vinyl acetate ethylene copolymer. Ana tarwatsa ƙwayoyin polymer a cikin ruwa kuma ana iya sake gina su zuwa yanayin ruwa. Wannan nau'in RDP yana da aikace-aikace da yawa da suka haɗa da busassun cakuda turmi, samfuran siminti da mahadi masu daidaita kai. Suna ba da kyakkyawar mannewa, sassauci da karko.
2. Acrylic redispersible polymer
Acrylic redisspersible polymers an yi su daga acrylic ko methacrylic copolymers. Ƙarfinsu na musamman da juriya na abrasion sun sa su dace don aikace-aikace inda dorewa yana da mahimmanci. Ana amfani da su a cikin mannen tayal, rufin waje da tsarin gamawa (EIFS), da gyaran turmi.
3. Ethylene-vinyl acetate redispersible polymer
Ethylene-vinyl acetate redispersible polymers an yi su daga ethylene-vinyl acetate copolymers. Ana amfani da su a aikace-aikace iri-iri ciki har da turmi siminti, grouts da tile adhesives. Suna da kyakkyawan sassauci da mannewa don amfani da su a cikin matsanancin yanayi.
4. Styren-butadiene polymer redispersible
An yi su ne daga styrene-butadiene copolymers masu sake tarwatsawa na Styren-butadiene. Ana amfani da su a aikace-aikace iri-iri da suka haɗa da gyare-gyare na kankare, mannen tayal da grouts. Suna da kyakkyawan juriya na ruwa da abubuwan mannewa.
5. Re-emulsifiable polymer foda
Re-emulsifiable polymer foda shine RDP da aka tsara don sake sakewa a cikin ruwa bayan bushewa. Ana amfani da shi a yawancin aikace-aikace inda samfurin ya fallasa ga ruwa ko danshi bayan amfani. Waɗannan sun haɗa da tile adhesives, grout, da caulk. Suna da kyakkyawan juriya na ruwa da sassauci.
6. Hydrophobic redispersible polymer foda
Hydrophobic redispersible polymer foda tsara don ƙara ruwa juriya na tushen siminti kayayyakin. Yawanci ana amfani da shi a aikace-aikace inda samfurin zai haɗu da ruwa, kamar su Insulation na waje da Tsarin Kammalawa (EIFS), mannen tayal na wurin wanka da kuma turmi na gyaran kankare. Yana da kyakkyawan juriya na ruwa da karko.
Redispersible latex foda abu ne mai mahimmanci wanda za'a iya amfani dashi a yawancin aikace-aikace. Akwai nau'ikan RDP da yawa, kowanne yana da kaddarorinsa na musamman da amfaninsa. Kyakkyawan mannewa, sassauci da dorewa ya sa su dace don amfani da samfurori iri-iri. Idan aka yi amfani da su daidai, za su iya taimakawa wajen inganta inganci da dawwama na yawancin kayan gini.
