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.
