Iyo poda yerabha inogadzirwa nekupisa kwakanyanya, kudzvanywa kwepamusoro, kupfapfaidza kuomesa uye homopolymerization nemhando dzakasiyana-siyana dzinoshanda-inosimudzira micropowders, iyo inogona zvakanyanya kuvandudza kugona kwekubatanidza uye kusimba kwesimba redhaka. , yakanakisa kupisa kuchembera kuita, zviri nyore zvinongedzo, zviri nyore kushandisa, zvinotibvumira kugadzira yakakwirira-yemhando yakaoma-yakasanganiswa dhaka. Zvinowanzo shandiswa zve dispersible polymer poda ndezvi:
Adhesives: matairi adhesives, adhesives ekuvaka uye kuvhara mapuranga;
Wall mortar: kunze thermal insulation mortar, dhaka rekushongedza;
Floor dhaka: dhaka rinozvimisa, dhaka rekugadzirisa, dhaka risina mvura, yakaoma poda interface agent;
Powder coatings: lime-cement plasters uye machira akagadziridzwa neputty poda uye latex poda yemukati nekunze madziro uye sirin'i;
Filler: tile grout, dhaka rekubatana.
Redispersible latex podahaidi kuchengetwa uye kutakurwa nemvura, kuderedza mari yekufambisa; nguva refu yekuchengetedza, antifreeze, nyore kuchengeta; diki yekurongedza vhoriyamu, uremu huremu, nyore kushandisa; Inogona kushandiswa se premix yakagadziridzwa ne synthetic resin, uye inongoda kuwedzera mvura kana uchishandisa, iyo isingangodzivisi kukanganisa mukusanganiswa panzvimbo yekuvaka, asiwo inovandudza kuchengetedzwa kwekugadzirisa chigadzirwa.
Mudhaka, ndeye kuvandudza kusasimba kwechinyakare simende dhaka senge brittleness uye yakakwirira elastic modulus, uye kupa simende dhaka zviri nani kuchinjika uye kusimba kwechisungo kusimba kuramba uye kunonoka kugadzirwa kwedhaka resimende. Sezvo iyo polymer uye dhaka zvichiumba inopindirana network chimiro, inoenderera polymer firimu inoumbwa mumapores, iyo inosimbisa chisungo pakati peaggregates uye inovhara mamwe mapores mudhaka. Naizvozvo, dhaka rakagadziridzwa mushure mekuomeswa rine kuita kuri nani pane simende dhaka. yave nani.
Dispersible polymer poda inoparadzirwa mufirimu uye inoita sekusimbisa sechipiri chekunamatira; iyo inodzivirira colloid inobatwa nedhaka system (iyo firimu haizoparadzwi nemvura mushure mekuumbwa kwefirimu, kana "secondary dispersion"); firimu-inogadzira polymer resin Sechinhu chinosimbisa chinogoverwa mukati medhaka system, nekudaro ichiwedzera kubatanidzwa kwedhaka.
