Ukwakheka komzimba nokwenziwa kwe-hook-beam yezitimela eziphakeme kakhulu kwenziwa kusetshenziswa i-aluminium alloy, eyaziwa ngezinzuzo zayo njengokuqina okuphansi, isilinganiso esihle sokuqina kwesisindo, ukumelana kahle nokushisa okuhle kakhulu. Ngokufaka esikhundleni sezinto zensimbi yendabuko nge-aluminium, isisindo somzimba wesitimela sincishiswa kakhulu, okuholela ekusetshenzisweni kwamandla okuphansi, ukungcoliswa kwemvelo okuncishisiwe, nokwakha izinzuzo zombili zezomnotho nezenhlalo.
Kodwa-ke, ama-alloys we-aluminium ne-aluminium anezakhiwo ezisebenzayo kakhulu zamakhemikhali. Yize benza ifilimu eliminyene le-oxide lapho livezwa umoya-mpilo emvelweni, ukuhlinzeka ngokumelana okungcono kokugqwala kunensimbi ejwayelekile, ukugcwala kusenokwenzeka lapho kusetshenziswa i-alumininum alloy ezitimeleni ezisheshayo. Imithombo yamanzi ewonakalisayo, kufaka phakathi ukuguquguquka, ukuguquguquka komkhathi, kanye nokuphuma kwamanzi kusuka emhlabathini ngesikhathi sokupaka, kungaphazamisa ifilimu ye-oxide. Ukugqwala e-Aluminium Alloy okusetshenzisiwe emzimbeni wezitimela eziphezulu kakhulu zibonisa ngokugqwala okufanayo, ukugqwala okuphelele, ukuqina kwe-crevice, kanye nokugqwala kwengcindezi, okwenza kube yinqubo eyinkimbinkimbi ethonywe yizo zombili izici zezemvelo nezakhiwo ze-alloy.
Kunezindlela ezahlukahlukene ze-anticorrosion ze-aluminium alloy, njengokusebenzisa izimbobo ze-anticorrosive ukuze zihlukanise ngempumelelo i-aluminium alloy substrate kusuka endaweni yangaphandle. Ukuhlanganiswa okujwayelekile kwe-anticorrosive yi-epoxy resin primer, esetshenziselwa kakhulu ukumelana kwamanzi okuhle, ukunamathela okuqinile okuqinile, kanye nokuhambisana nezingubo ezihlukahlukene.
Kodwa-ke, kuqhathaniswa nezindlela zokuvimbela ngokomzimba, indlela ephumelelayo yokwelashwa kwamakhemikhali. Ngemuva kokuphathwa kwe-Aluminium ne-Aluminium Alloys, ubukhulu bomkhiqizo kanye nokunemba kwemishini kuhlala kungathinteki, futhi akukho zinguquko ngokubukeka noma umbala. Le ndlela ilula futhi ihlinzeka ngefilimu yokuhamba eqinile futhi evikelekile kakhulu ngokuqhathaniswa nezembatho zendabuko zendabuko. Ifilimu yokudlula ekwakheke ngokwelashwa kwe-aluminium Alloy Ukuphambuka kuzinzile futhi kunokumelana okuphezulu kokugqwala kunezimbozo zendabuko zendabuko, ngezinzuzo ezingeziwe zokuzilungiselela ukusebenza.
Isixazululo sethu sokuhamba nge-chromium-free saprivation, i-KM0425, ilungele ukudlula izinto ze-aluminium, ama-alloys we-aluminium, kanye nemikhiqizo ye-aluminium efayo, ethuthukisa ukumelana nokugqwala kwawo. Kungumkhiqizo omusha futhi osezingeni eliphezulu ngokuphumelela kwenhloso ejwayelekile yezinto ze-aluminium. Kwenziwe ngama-organic acid, izinto zomhlaba ezingandile, izinhlanzi ezisezingeni eliphakeme zokugqwayiza, kanye nenani elincane le-accelerators ephezulu ye-molecular-isisindo, i-acid-free ashevu, ayinasizi. Ukuhambisana namazinga wamanje we-Rohs wezemvelo, ukusebenzisa lesi sixazululo sokuhamba kuqinisekisa ukuthi inqubo yokuphumelela ayilimazi umbala wokuqala nobukhulu bendawo yokusebenza ngenkathi kuthuthukiswa kakhulu ukumelana kwezinto ze-aluminium ukuze kufakwe usawoti.
