Odakeni, i-polymer powder ehlakazeka kabusha ingathuthukisa izici zokwakha ubunjiniyela be-powder yerabha, ithuthukise uketshezi lwempushana yerabha, ithuthukise i-thixotropy kanye nokumelana ne-sag, ithuthukise amandla okuhlangana empushana yerabha, ithuthukise ukunyibilika kwamanzi, futhi yandise isikhathi lapho ivulwa. ezweni langaphandle. phakathi. Ngemuva kokuthi udaka lukasimende lomile futhi luqiniswe, lungakhuphula amandla okucindezela, lwandise amandla okuqina, lwehlise isikhunta esinwebekayo, futhi sithuthukise ukucaciswa. redispersible polymer powder inokunamathela okuhle kwefilimu, futhi ukusetshenziswa kwayo kungabonakala kumaphrojekthi wokwakha nokuhlobisa.
Ifilimu ye-latex yenjoloba yerabha inesakhiwo esizidonsayo, esingakhulula amandla asekelayo ekuhlanganyeleni ngehange lodaka lukasimende. Ngokwalokhu kuqina kwangaphakathi, udaka lukasimende lugcinwa ngokujwayelekile futhi ukuhlangana kwethimba lodaka lukasimende kuyathuthukiswa. Ukuba khona kwe-polymer ephezulu enwebekayo kuthuthukisa i-ductility kanye ne-ductility yodaka lukasimende. Umgomo wokwandisa ukucindezeleka kwesivuno namandla okucindezela angasebenzi kanje: Lapho amandla ekhululwa, ama-micro-cracks azobambezela isikhathi kuze kube yilapho ukucindezeleka kwe-in-situ kwanda ngenxa yokwanda kwe-ductility kanye ne-ductility. Ngaphezu kwalokhu, izifunda ze-polymer ezihlanganisiwe nazo zinomthelela wokuvimbela emifantwini emincane ehlanganiswe ukuqhekeka. Ngakho-ke, i-latex powder yemvelo ehlakazekile ingakhuphula ukucindezeleka okungasebenzi kanye nobunzima obungasebenzi bempahla eluhlaza. Ifilimu ye-polymer odakeni lukasimende olulungisiwe lwe-polymer iyingozi enkulu odakeni lukasimende oluqinile. Ukuhlakazwa kwezimpushana ze-polymer ezihlakazekayo kudlala enye indima ehamba phambili ekhasini, okuwukuthuthukisa ukunamathela kwezinto ezingavuthiwe lapho kuthintana khona.
Iningi lezimpushana ze-polymer ezihlakazekayo abantu abavame ukuzibona ezakhiweni zimhlophe qhwa, nakuba amanye ama-shades angase avele. Ukwakhiwa kwe-latex powder e-redispersible ikakhulukazi yakhiwe nge-polymer epoxy resin preservative (yangaphakathi nangaphandle) yokulungisa isisombululo se-colloid kanye ne-ejenti yokumelana. Phakathi kwazo, i-polymer epoxy resin ephezulu itholakala endaweni eyinhloko yezinhlayiya ze-raber powder futhi iyisici esiyinhloko se-polymer powder ehlakazekayo.
Impushana ye-polymer ehlakazekayo ayidingi amanzi kampompi ekugcinweni nasekuthuthweni, okungasindisa izindleko zokuhamba zamamojula wokwakha ubunjiniyela futhi yenze ezokuthutha zibe lula futhi zisheshe. Impushana yemvelo ye-latex ehlakazeka kabusha ekhiqizwa imboni yodaka lukasimende ineshalofu lesikhathi eside futhi ingagcinwa isikhathi eside ngaphandle kokukhathazeka mayelana nezinga lokushisa eliphansi kakhulu eliqandayo kanye nesitoreji esikahle. Isikhwama ngasinye se-polymer powder ehlakazeka sincane ngevolumu, silula ngesisindo, futhi kulula ukusisebenzisa.
