Tisati tave kutaura nezveyedu aruminiyamu extrusion maitiro, ino nguva weihua (makambani ealuminium extrusion) anoda kukuzivisa muchidimbu kwauri mashandisiro ataiita zvigadzirwa zveindasitiri yealuminium extrusion zvinogadzirwa.

1. Kunyorera kunyorera

(Kunyorera kunyorera ndiyo yekutanga maitiro ekugadzira aluminium)

(1) Zvinongedzo:

Zvinoenderana neicho chiwanikwa chechiratidzo chinofanira kugadzirwa, verenga huwandu hwekuwedzera hwezvinhu zvakasiyana zvealloy, uye zvinowirirana zvine mutsindo zvakasiyana mbishi zvinhu.

(2) Kunyorera:

Izvo zvinowirirana mbishi zvinhu zvinonyungudika muhuvhenekeri inonyunguduka zvinoenderana nehunyanzvi zvinodiwa, uye marara uye magasi ari mukunyungudika anobviswa zvinobudirira nenzira yeacassassing uye slag kubvisa kunatsa.

(3) Kukanda:

Iyo yakanyungudutswa aruminiyamu yakanyorova uye inokandirwa mumativi matanda eakasiyana maratidziro kuburikidza yakadzika tsime kukanda sisitimu pasi pemamwe mamiriro ekurasa.

2.Kuburitsa:

Extrusion ndiyo nzira yekuumba profiles.Kutanga, zvinoenderana neyakagadzirwa chigadzirwa chikamu dhizaini, gadzira chakuvhuvhu, shandisa iyo extruder ichave inopisa yakanaka kutenderera yakakanda bar bar extrusion fomu fomu.

Iyo inowanzo shandiswa 6063 alloy inoburitswa neyaka-kudzikiswa mweya kudzima maitiro uye yekunyepedzera kukwegura maitiro kupedzisa kupisa kurapwa. Iyo kupisa kurapwa sisitimu yeanopisa-anorapika chiwanikwa chemakadhi akasiyana akasiyana.

3. Ruvara

(Pano isu tinonyanya kutaura nezve oxidation), extruded aluminium alloy profile, iyo yekumusoro ngura kuramba haina kusimba, inofanirwa kuvezwa anodized yekurapa kwepasirese kuwedzera iyo corrosion kuramba yealuminium, kupfeka kuramba uye kutaridzika kweiyo yakanaka degree.

Maitiro makuru ndeaya anotevera:

(1) Pamusoro pretreatment:

Makemikari kana epanyama nzira dzinoshandiswa kuchenesa pamusoro peiyo profil kufumura iyo yakachena substrate, kuti uwane yakakwana uye gobvu rekugadzira oxide firimu. Mirror kana matt husovha hunogona kuwanikwa zvakare nenzira.

(2) Anodic oxidation:

Mushure mekumisikidzwa kwepasirese, pasi pemamwe matekinoroji mamiriro, anodic oxidation inoitika pane iyo substrate pamusoro, zvichikonzera kuomarara, kutyisa uye kusimba kushambadza AL2O3 firimu yakaturikidzana.

(3) Hole chisimbiso:

Iyo pores yeiyo porous oxide firimu yakaumbwa mushure meodic oxidation yakavharwa kuwedzera iyo anti-kusvibiswa, anti-ngura uye kupfeka kuramba kweiyo oxide firimu.Oididation firimu haina kuchena uye yakajeka, iko kushandiswa kwesimba kushambadza kweiyo oxidation firimu usati waiswa chisimbiso, mufirimu gomba adsorption deposition yeimwe simbi munyu, inogona kuita kuti chimiro chitarisike chiratidze zvakasikwa (chena sirivheri) zvimwe kunze kwemavara mazhinji, senge: nhema, ndarira, goridhe uye isina simbi ruvara.
