Phofo ea Polymer e Nchafalitsoeng (RDP) ke polymer e sebelisoang lits'ebetsong tse fapaneng. RDP ke phofo e qhibilihang ka metsing e entsoeng ka mefuta e fapaneng ea li-polymer, ho kenyeletsoa vinyl acetate, vinyl acetate ethylene, le li-resin tsa acrylic. Phofo e kopantsoe le metsi le lintho tse ling tse tlatsetsang ho etsa slurry, e ntan'o sebelisoa ho 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. Sehloohong sena, re tla hlahloba tse ling tsa mefuta e tloaelehileng ea RDP le lits'ebetso tsa eona.
1. Polima e qhalakantsoeng hape ea acetate ea vinyl
Li-polymer tse qhalakantsoeng hape tsa vinyl acetate ke mofuta o tloaelehileng haholo oa RDP. Li entsoe ka vinyl acetate le vinyl acetate ethylene copolymer. Likaroloana tsa polymer li qhalakantsoeng ka metsing 'me li ka fetoloa hore e be boemo ba mokelikeli. Mofuta ona oa RDP o na le mefuta e mengata ea lits'ebetso ho kenyeletsoa le li-mortar tse kopantsoeng tse omileng, lihlahisoa tsa samente le metsoako e ikamahanyang. Li fana ka ho khomarela ho hoholo, ho tenyetseha le ho tšoarella.
2. Polymer e qhalakantsoeng hape ea acrylic
Li-polymer tse qhalakantsoeng hape tsa acrylic li entsoe ka li-copolymer tsa acrylic kapa tsa methacrylic. Matla a tsona a ikhethang le ho hanyetsa ho khohlela li etsa hore li be ntle bakeng sa lits'ebetso moo ho tšoarella ho leng bohlokoa. Li sebelisoa ho likhomaretsi tsa thaele, litsamaiso tsa ho kenya mocheso ka ntle le ho qeta (EIFS), le li-mortar tsa tokiso.
3. Polima e qhalakantsoeng hape ea ethylene-vinyl acetate
Li-polymer tse qhalakantsoeng hape tsa ethylene-vinyl acetate li entsoe ka li-copolymer tsa ethylene-vinyl acetate. Li sebelisoa lits'ebetsong tse fapaneng ho kenyeletsoa le li-mortar tsa samente, li-grout le li-glue tsa thaele. Li na le ho tenyetseha ho hoholo le ho khomarela bakeng sa tšebeliso libakeng tse nang le khatello e phahameng.
4. Polymer e qhalakantsoeng hape ea Styrene-butadiene
Li-polymer tse qhalakantsoeng hape tsa styrene-butadiene li entsoe ka li-copolymer tsa styrene-butadiene. Li sebelisoa lits'ebetsong tse fapaneng ho kenyeletsoa le li-mortar tsa konkreite, likhomaretsi tsa thaele le li-grout. Li na le tšireletso e ntle ea metsi le thepa ea sekhomaretsi.
5. Phofo ea polymer e ka emolisoang hape
Phofo ea polymer e ka emulsifiable hape ke RDP e etselitsoeng ho emulsifiable hape ka metsing kamora ho oma. E sebelisoa lits'ebetsong tse ngata moo sehlahisoa se pepesetsoang metsi kapa mongobo kamora ho sebelisoa. Tsena li kenyelletsa likhomaretsi tsa thaele, grout, le caulk. Li na le ho hanyetsa metsi le ho tenyetseha ho hoholo.
6. Phofo ea polymer e qhalanngoang hape e sa tšabeng metsi
Phofo ea polymer e qhalakantsoeng hape e nang le hydrophobic e etselitsoeng ho eketsa khanyetso ea metsi ea lihlahisoa tse thehiloeng 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 li-mortar tsa konkreite tse lokisoang. E na le khanyetso e ntle ea metsi le ho tšoarella.
Phofo ea latex e qhalakantsoeng hape ke thepa e feto-fetohang e ka sebelisoang lits'ebetsong tse ngata. Ho na le mefuta e 'maloa ea RDP, e' ngoe le e 'ngoe e na le litšobotsi le ts'ebeliso ea eona e ikhethang. Ho khomarela ha tsona hantle, ho tenyetseha le ho tšoarella ho etsa hore li be ntle bakeng sa tšebeliso lihlahisoa tse fapaneng. Ha li sebelisoa ka nepo, li ka thusa ho ntlafatsa boleng le bophelo bo bolelele ba lihlahisoa tse ngata tsa kaho.
