Ifilimu yeziphinde zisasazweipholimaumguboiRDPiyalastiki kwaye yomelele, kumathambo aqinileyo abunjwa kukugalelwa kodaka lwesamente. Phakathi kwamasuntswana odaka lwesamente, lusebenza njengesihlanganisi esishukumayo, esinokuthwala imithwalo ephezulu yokuguqulwa, ukunciphisa uxinzelelo, kunye nokuphucula ukuxhathisa kunye nokugoba.
Iipolymer powders ezikwaziyo ukuphinda ziphuculwe ziphucula ukuchasana kwempembelelo yeereyini ze-thermoplastic. Ifilimu ethambileyo efakwe phezu kweengqungquthela zodaka, kwaye i-latex powder edibeneyo iyakwazi ukufunxa impembelelo yamandla angaphandle, iphumle ngaphandle komonakalo, ngaloo ndlela iphucula ukuchasana kwempembelelo yodaka. I-latex powder edibeneyo i-redispersible yandisa i-hydrophobicity, inciphisa ukufunxa kwamanzi, kwaye inokuphucula i-microstructure yodaka lwesamente.
Ipolymer yayo yenza inethiwekhi engenakuguqulwa ngexesha le-cement hydration, yongeza kwakhona i-latex powder. I-capillary kwi-gel ye-cement ivaliwe ukuvala ukufunxa kwamanzi, ukuthintela ukungena kwamanzi, kunye nokuphucula ukungabonakali. Umgubo wepolymer odispersible uphucula ukuqina kokumelana ne-abrasion.
Redispersible latex powder isetyenziswa ikakhulu kudaka lwesamente olomileyo kushishino lolwakhiwo, kwaye sisongezo esibalulekileyo sodaka olomileyo lwesamente. Indima yodaka lwesamente eyomileyo ibalulekile, enokuphucula amandla okubopha kunye nokudityaniswa kwezinto, ukuphucula amandla okugoba okulastiki kunye namandla aguquguqukayo ezinto eziphathekayo, ukuphucula ukuxhathisa kwe-freeze-nyibiliki yezinto eziphathekayo, kunye nokuphucula ukuxhathisa kwemozulu, ukuhlala ixesha elide. kunye nokugqoka ukuchasana kwezinto. Ukuphucula i-hydrophobicity yezinto eziphathekayo, ukunciphisa izinga lokufunxa kwamanzi, ukuphucula ukusebenza, ukunciphisa izinga lokunciphisa izinto, kunye nokuthintela ngokufanelekileyo ukuqhekeka. , ukuphucula ukugoba kunye nokuxhatshazwa kwe-tensile.
