Ngaphambi kokuthi sikhulume ngeyethu inqubo ye-aluminium extrusion, kulokhu i-weihua (izinkampani ze-aluminium extrusion) zingathanda ukwethula kafushane kuwe ukuthi siyisebenzisa kanjani imikhiqizo yezimboni ze-aluminium extrusion ekhiqizwa.
1. Ukuncibilika kokulingiswa
(Ukuncibilika kokuncibilika kuyinqubo yokuqala yokukhiqizwa kwe-aluminium)
(1) Izithako:
Ngokuya ngomkhiqizo othile we-alloy ozokhiqizwa, bala inani lokungezwa lezinto ezahlukahlukene ze-alloy, bese uqondanisa ngokufanelekile izinto zokusetshenziswa ezahlukahlukene.
(2) Ukuncibilikisa:
Izinto zokusetshenziswa ezihambisanayo ziyancibilika esithandweni esincibilikayo ngokuya ngezidingo zobuchwepheshe, futhi ukungcola kanye namagesi akulencibilikisi kususwa ngempumelelo kusetshenziswa ukucwengwa kwe-degassing nokususwa kwe-slag.
(3) Ukulingisa:
I-aluminium encibilikisiwe ipholile futhi iphonswe kwizinduku eziyindilinga zokucaciswa okuhlukahlukene ngohlelo olujulile lokusakaza kahle ngaphansi kwezimo ezithile zokuphonsa.
2.Ukukhishwa:
I-Extrusion iyindlela yokwakha amaphrofayli.Okokuqala, ngokusho komklamo womkhakha womkhiqizo wephrofayili, yenza isikhunta, sebenzisa i-extruder izofudunyezwa ifreyimu enhle eyindilinga ebunjiwe.
Ingxubevange esetshenziswa kakhulu engama-6063 ikhishwa ngenqubo yokuqeda umoya opholile kanye nenqubo yokuguga yokufakelwa ukuqedela ukwelashwa kokushisa. Uhlelo lokwelashwa kokushisa lwengxubevange ephathwa ukushisa yamamaki ahlukile yehlukile.
3. Umbala
(Lapha sikhuluma kakhulu nge-oxidation), iphrofayili ye-aluminium extruded, ukumelana kwayo nokugqwala komhlaba akunamandla, kufanele kudayiselwe ukwelashwa kwendawo ukukhulisa ukumelana nokugqwala kwe-aluminium, ukugqoka ukumelana nokubukeka kwezinga elihle.
Inqubo enkulu imi kanje:
(1) Surface pretreatment:
Izindlela zamakhemikhali noma zomzimba zisetshenziselwa ukuhlanza ubuso bephrofayili ukudalula i-substrate emsulwa, ukuze kutholakale ifilimu ye-oxide yokufakelwa ephelele futhi eminyene. I-Mirror noma i-matt surface nayo ingatholwa ngemishini.
(2) Anodic namachibi:
Ngemuva kokuphindaphindwa komhlaba, ngaphansi kwezimo ezithile zobuchwepheshe, i-anodic oxidation ivela endaweni engaphansi komhlaba, okuholele kusendlalelo sefilimu se-AL2O3 esinyene, esinamandla.
(3) Hole uphawu:
Ama-pores we-porous oxide film akhiwe ngemuva kwe-anodic oxidation avaliwe ukukhulisa i-anti-pollution, anti-corrosion nokugqoka ukumelana nefilimu ye-oxide.Oididation ayinambala futhi isobala, ukusetshenziswa kwe-adsorption eqinile yefilimu ye-oxidation ngaphambi kokubekwa uphawu, ekubekweni komgodi wokukhishwa kwefilimu ngosawoti othile wensimbi, kungenza ukubonakala kwephrofayili kubonise okwemvelo (okumhlophe kwesiliva) ngaphandle kwemibala eminingi, njengokuthi: umbala omnyama, wethusi, igolide nensimbi engagqwali.
