Redispersible Polymer Powder (RDP) ke polymer e sebelisoang lits'ebetsong tse fapaneng. RDP ke phofo e qhibilihang ka metsing e entsoeng ka lipolymer tse fapaneng, ho kenyelletsa le vinyl acetate, vinyl acetate ethylene, le li-resin tsa acrylic. Phofo e kopantsoe le metsi le lisebelisoa tse ling ho etsa slurry, e ntan'o sebelisoa ho li-substrates tse fapaneng. Ho na le mefuta e 'maloa ea RDP, e' ngoe le e 'ngoe e na le thepa ea eona e ikhethang le ts'ebeliso ea eona. Sehloohong sena, re tla hlahloba mefuta e meng e atileng haholo ea RDP le lits'ebetso tsa eona.
1. Vinyl acetate redispersible polymer
Vinyl acetate redispersible polymers ke mofuta o atileng haholo oa RDP. Li entsoe ka vinyl acetate le vinyl acetate ethylene copolymer. Likaroloana tsa polymer li qhalakanngoa ka metsing 'me li ka tsosolosoa ho ba boemo ba metsi. Mofuta ona oa RDP o na le mefuta e mengata ea lits'ebetso tse kenyelletsang seretse sa motsoako o omileng, lihlahisoa tsa samente le metsoako ea ho itekanya. Li fana ka ho khomarela hantle, ho tenyetseha le ho tšoarella.
2. Acrylic redispersible polymer
Acrylic redispersible polymers li entsoe ka acrylic kapa methacrylic copolymers. Matla a bona a ikhethang le ho hanyetsa ha abrasion ho li etsa hore li tšoanelehe bakeng sa lits'ebetso moo ho tšoarellang ho leng bohlokoa. Li sebelisoa ka har'a likhomaretsi tsa lithaele, ho kenella ka ntle le litsamaiso tsa ho qetela (EIFS), le ho lokisa seretse.
3. Ethylene-vinyl acetate redispersible polymer
Ethylene-vinyl acetate redispersible polymers li entsoe ka ethylene-vinyl acetate copolymers. Li sebelisoa mefuteng e fapaneng ea lits'ebetso tse kenyelletsang seretse sa samente, li-grouts le likhomaretsi tsa lithaele. Li na le ho tenyetseha le ho khomarela hantle bakeng sa ho sebelisoa maemong a khatello e phahameng.
4. Styrene-butadiene redispersible polymer
Styrene-butadiene redispersible polymers li entsoe ka styrene-butadiene copolymers. Li sebelisoa mefuteng e fapaneng ea lits'ebetso tse kenyelletsang seretse sa ho lokisa konkreite, likhomaretsi tsa lithaele le li-grouts. Li na le thepa e ntle ea ho thibela metsi le ho khomarela.
5. Re-emulsifiable polymer powder
Re-emulsifiable polymer powder ke RDP e etselitsoeng ho etsoa hape ka metsi ka mor'a ho omisa. E sebelisoa lits'ebetsong tse ngata moo sehlahisoa se pepesehelang metsi kapa mongobo ka mor'a hore se sebelisoe. Tsena li kenyelletsa likhomaretsi tsa lithaele, grout, le caulk. Li na le matla a ho hanyetsa metsi le ho feto-fetoha ha maemo.
6. Hydrophobic redispersible polymer phofo
Hydrophobic redispersible polymer powders tse etselitsoeng ho eketsa khanyetso ea metsi ea lihlahisoa tse thehiloeng ho samente. Hangata e sebelisoa lits'ebetsong moo sehlahisoa se tla kopana le metsi, joalo ka Exterior Insulation and Finishing Systems (EIFS), likhomaretsi tsa lithaele tsa letamo la ho sesa le lirekere tsa ho lokisa konkreite. E na le ho hanyetsa metsi ho babatsehang le ho tšoarella.
Redispersible latex powder ke sesebelisoa se feto-fetohang se ka sebelisoang lits'ebetsong tse ngata. Ho na le mefuta e 'maloa ea RDP, e' ngoe le e 'ngoe e na le thepa ea eona e ikhethang le ts'ebeliso ea eona. Ho khomarela ha tsona, ho tenyetseha le ho tšoarella ha tsona ho etsa hore e be tse loketseng ho sebelisoa lihlahisoa tse ngata tse fapaneng. Ha li sebelisoa ka nepo, li ka thusa ho ntlafatsa boleng le bophelo bo bolelele ba lihlahisoa tse ngata tsa moaho.
