Phambi kokuba sithethe ngezethu Inkqubo yealuminium extrusionNgeli xesha i-weihua (iinkampani ze-aluminium extrusion) zingathanda ukwazisa ngokufutshane indlela esizisebenzisa ngayo iimveliso ze-aluminium extrusion eziveliswayo.

1. Ukunyibilika

(Ukunyibilika kokunyibilika yinkqubo yokuqala yemveliso yealuminium)

(1) Izithako:

Ngokwe-alloy brand ethile ekufuneka ivelisiwe, ukubala inani lokudityaniswa kwezinto ezahlukeneyo ze-alloy, kwaye uthelekise ngokufanelekileyo izinto ezahlukeneyo zokwenza izinto.

(2) Ukunyibilikisa:

Izinto eziluhlaza ezihambelanayo ziyanyibilika kwiziko lokunyibilikisa ngokweemfuno zetekhnoloji, kwaye ukungcola kunye neegesi ezikunyibilikisi zisuswe ngokufanelekileyo kusetyenziswa i-degassing kunye nokususwa kwe-slag yokusulungekiswa.

(3) Uphose:

I-aluminiyamu etyhidiweyo iyaphola kwaye iphoswe kwiirandi ezijikelezileyo zeenkcukacha ezahlukeneyo ngenkqubo enzulu yokuphosa phantsi kweemeko ezithile.

2.Ukongezwa:

I-extrusion yindlela yokwenza iiprofayili. Okokuqala, ngokokuyilwa kwecandelo leemveliso zeprofayili, ukwenza isikhunta, ukusebenzisa i-extruder kuya kufudunyezwa kwifom ye-bar extrusion elungileyo.

I-alloy 6063 esetyenziswa ngokuxhaphakileyo ikhutshelwa ngaphandle kwenkqubo yokucima umoya opholileyo kunye nenkqubo yokuguga engeyiyo yokugqibezela unyango lobushushu.Inkqubo yokunyanga ubushushu yengxubevange enganyangekiyo yobushushu kumabakala ahlukeneyo yahlukile.

3. Umbala

(Apha sithetha kakhulu nge-oxidation), iprofayili ye-aluminium ekhutshiweyo, ukunganyangeki kwayo komhlaba akunamandla, kufuneka kwenziwe i-anodized kunyango lonyusa ukonyusa umhlwa we-aluminium, ukunxiba ukumelana nokubonakala kwesidanga esihle.

Inkqubo ephambili yile ilandelayo:

(1) umphezulu pretreatment:

Iikhemikhali okanye iindlela zomzimba zisetyenziselwa ukucoca umphezulu weprofayile ukubhengeza i-substrate emsulwa, ukuze kufunyanwe ifilimu ye-oxide yokufakelwa epheleleyo kunye eshinyeneyo.

(2) i-oxidation ye-Anodic:

Emva kokuphathwa kwangaphambili komhlaba, phantsi kweemeko ezithile zetekhnoloji, iodid oxidation yenzeka kumhlaba ongaphantsi, okukhokelela kubungqingqwa obunamandla, obunamandla kunye nobomeleleyo be-adsorption AL2O3.

(3) Hole ukutywina:

Ifreyimu ye-oxide ye-porous eyenziwe emva kokuba i-oxidation ye-anodic ivaliwe ukonyusa ukungcola, anti-umhlwa kunye nokunxiba ukumelana nefilimu ye-oxide.Oididation ayinambala kwaye iyabonakala, ukusetyenziswa kwe-adsorption eyomeleleyo yefilimu ye-oxidation ngaphambi kokutywinwa, kwifilimu umngxunya wokubekwa kwintengiso yetyuwa yesinyithi, unokwenza imbonakalo yeprofayili ibonise indalo (isilivere emhlophe) ngaphandle kwemibala emininzi, enje ngombala omnyama, ubhedu, igolide kunye nombala wesinyithi.
