I-polymer powder enokuchithwa kwakhonai-polymer powder emhlophe ekhululekile enokuthi iphinde ifakwe kwakhona kwaye ihlakazwe emanzini ukuze yenze i-emulsion ezinzileyo. Inokuxutywa kunye nezinye izinto ezinomgubo ezifana nesamente, isanti, i-aggregate lightweight, njl njl kumzi-mveliso wemveliso ngokomlinganiselo othile kwimeko eyomileyo ukufumana umgangatho ophezulu kunye nokulula ukusebenzisa i-samente eyomileyo exutywe nodaka, enokunciphisa ukwakhiwa kwendawo. Iphutha kunye nokuphazamiseka xa udibanisa kunye nokulinganisa nge-emulsion.
Imisebenzi emithandathu yomgubo wepolymer onokuphinda uhlakazwe:
1. Ukuphucula amandla okubambelela kunye nokubambisana
Kwiimveliso zodaka olomileyo lwesamente, kubaluleke kakhulu ukongeza umgubo wepolymer ohlakazekayo. Kucacile kakhulu ukuphucula amandla okudibanisa kunye nokudibanisa kwezinto eziphathekayo. Oku kubangelwa ukungena kwe-polymer particles kwi-pores kunye ne-capillaries ye-matrix ye-samente, kunye nokubunjwa kwamandla adibeneyo kunye ne-samente emva kwe-hydration. Ngenxa yokunamathela okugqwesileyo kwe-polymer resin ngokwayo, inokuphucula ukunamathela kweemveliso zodaka lwesamente kwi-substrates, ngakumbi izibophelelo ze-inorganic ezifana nesamente zibophelelwe kwi-substrates yezinto eziphilayo ezifana nemithi, i-fiber, i-PVC kunye ne-EPS. Ukuphuculwa komsebenzi ongemhle kunesiphumo esicacileyo.
2. Ukuphucula ukugoba kunye nokumelana nokuqina
Kwi-skeleton eqinile eyenziwe yi-hydration ye-cement mortar, ifilimu ye-polymer i-elastic kwaye inzima. Phakathi kweengqungquthela zodaka lwesamente, lisebenza njengembumba eshukumayo, enokumelana nemithwalo ephezulu yokuguqulwa kunye nokunciphisa uxinzelelo, okwenza i-Tensile kunye nokugoba ukugoba kuphuculwe.
3. Ukuphucula ukuxhathisa impembelelo
Redispersible ipolymer powder, thermoplastic resin. Ifilimu ethambileyo efakwe phezu kweengqungquthela zodaka, ezinokuthatha impembelelo yamandla angaphandle kwaye ziphumle ngaphandle kokuphuka, ngaloo ndlela ziphucula ukuchasana kwempembelelo yodaka.
4, ukuphucula i-hydrophobicity kunye nokunciphisa izinga lokufunxa kwamanzi
Ukongeza i-polymer powder echithwayo kunokuphucula i-microstructure yodaka lwesamente. I-polymer yayo yenza inethiwekhi engenakuguqulwa kwinkqubo ye-cement hydration, ivala i-capillary kwi-gel ye-cement, ivimba ukuxutywa kwamanzi, ikhusela ukungena kwamanzi, ngaloo ndlela iphucula ukungaphumeleli.
5. Ukuphucula ukumelana nokunxiba kunye nokuqina
Ukongezwa kwepolymer powder echithwayo kunokunyusa ukudibanisa okuxineneyo phakathi kweengqungquthela zodaka lwesamente kunye nefilimu yepolymer. Ukuphuculwa kwamandla okubambisana ngokuhambelanayo kuphucula amandla omdaka ukumelana noxinzelelo lwe-chear, ukwenzela ukuba izinga lokunxiba lincitshiswe, ukuxhathisa ukunxiba kuphuculwe, kwaye ubomi benkonzo yodaka buhlala ixesha elide.
6. Ukuphucula ukuzinza kwe-freeze-thaw kunye nokuthintela ngokufanelekileyo ukuqhekeka kwezinto
I-polymer powder edispersible, iplastiki ye-resin ye-thermoplastic, inokuwoyisa umonakalo wokwandiswa kwe-thermal kunye nokucutha okubangelwa utshintsho lwamaqondo obushushu kwizinto zodaka lwesamente. Ukoyisa iintsilelo zodaka olulula lwe-samente kunye ne-deformation enkulu yokumisa i-shrinkage kunye nokuqhekeka okulula, kunokwenza izinto eziguquguqukayo, ngaloo ndlela kuphuculwe ukuzinza kwexesha elide lezinto eziphathekayo.
