Ukusetyenziswa kweTekhnoloji yoKuziphilisa yokuZiphilisa kwi-Powder Coatings

Ukusukela ngo-2017, abaninzi ababoneleli beekhemikhali abatsha abangena kwishishini lokugquma ipowder babonelele ngoncedo olutsha lokuqhubela phambili kobuchwephesha bokugquma umgubo. Itekhnoloji yokuziphilisa yokwambathisa evela kwi-Autonomic Materials Inc. (AMI) ibonelela ngesisombululo ekwandeni kokuchasa kokubola kwe-epoxy. Ipeyinti.
I-coating self-healing technology isekelwe kwi-microcapsule ene-core-shell structure eyenziwe yi-AMI kwaye inokulungiswa xa isambatho sonakaliswe. Le microcapsule i-post-mixed Ekulungiseleleni inkqubo yokugcoba umgubo.

Emva kokuba i-epoxy powder ephilisayo yonakele, i-microcapsules iya kwaphulwa kwaye izaliswe kumonakalo. Ngokombono womsebenzi wokugquma, le teknoloji yokuzilungisa iya kwenza i-substrate ingabonakali kwindalo, kwaye inceda kakhulu ukuxhathisa ukubola.

UGqrrald O. Wilson, iSekela likaMongameli we-AMI Technologies, ubonise ukuthelekiswa kweziphumo zovavanyo lokutshiza ityuwa kwi-powder coatings kunye nangaphandle kwe-microcapsules eyongezelelweyo. Iziphumo zibonise ukuba i-epoxy powder coating equkethe i-microcapsules inokulungisa ngokufanelekileyo imikrwelo kunye nokuphucula ukuxhathisa kwetyuwa. Iimvavanyo zibonisa ukuba ukugquma kunye ne-microcapsules kunokunyusa ukunyanzeliswa kwe-corrosion ngaphezu kwamaxesha e-4 phantsi kweemeko ezifanayo zokutshiza ityuwa.
UDkt Wilson uphinde waqwalasela ukuba ngexesha lokuveliswa kwangempela kunye nokugubungela i-powder powder, i-microcapsules kufuneka igcine ingqibelelo yazo, ukwenzela ukuba kuqinisekiswe ukuba iingubo ziyakwazi ukulungiswa ngokufanelekileyo emva kokuphulwa kwengubo. Okokuqala, ukuze ugweme ukutshatyalaliswa kwesakhiwo se-microcapsule ngenkqubo ye-extrusion, emva kokuxuba kukhethwe; ukongeza, ukwenzela ukuba kuqinisekiswe ukusasazeka okufanayo, i-shell shell ehambelana nezinto eziqhelekileyo zokugquma umgubo zenziwe ngokukodwa; ekugqibeleni, iqokobhe kwakhona kuqwalaselwa uzinzo lobushushu eliphezulu, Kuphephe ukuqhekeka ngexesha zokufudumeza.
Ukubaluleka kobu buchwepheshe butsha kukuba ibonelela ngophuculo olubalaseleyo ekuxhathiseni umhlwa ngaphandle kokusetyenziswa kwesinyithi, i-chromium enehexavalent, okanye ezinye iikhompawundi eziyingozi. Ezi zogquma azinayo kuphela iipropati zokuqala ezamkelekileyo, kodwa zibonelela ngeempawu ezintle zomqobo nangona emva komonakalo omkhulu kwi-substrate.
