Imisebenzi emine emikhulu yokulungiswa kwangaphambili kokuqedwa kwe-aluminium alloy surface

Lapho iphrofayili ye-aluminium extrusion iphathwa kuqala endaweni ngesikhathi sokukhiqiza, ukumelana nokugqwala kanye nezakhiwo zokuhlobisa zendawo ye-aluminium zingathuthukiswa ngempumelelo.

Umsebenzi 1: Ngokusebenzisa imithi yokwelapha indawo engaphezulu efana ne-sandblasting kanye nokubotshwa kwamakhemikhali, ukwelapha kusengaphambili kudala ukwakheka okumaholoholo okuncane phezulu ukuze kwakheke izingosi zokubambelela zemishini zokumbozwa kwempushana. Ubulukhuni obufanele bobuso bungathuthukisa ngokuphawulekayo umphumela wokumisa wemishini wezigqoko.

Umsebenzi wesi-2: Ngokusebenzisa izindlela zokwelapha zokuvula indawo ezinjengama pickling kanye ne-alkaline etching, ukwelashwa kusengaphambili kususa ungqimba lwe-inert oxide ngaphezulu, kuveza indawo yensimbi entsha futhi kuthuthukise ukusebenza kwamakhemikhali angaphezulu. Ukwelashwa kwentokozo yokuguqulwa kwamakhemikhali kwakha ifilimu yokuguqula esebenzayo endaweni ukuze kuhlinzekwe amasayithi okubopha amakhemikhali okunamathela. Kuphrofayela ye-aluminium esetshenziswa kumafasitela nomnyango wamaphrofayela e-aluminium asezingeni eliphezulu, kungase kudingeke izinqubo ezimbili noma ezintathu ezilandelanayo zokwelashwa kwendawo.

Umsebenzi wesi-3: Ukwelashwa kusengaphambili kuthinta amandla okumanzisa kanye nokuhlangana kobuso phakathi kokunameka ne-substrate, futhi kuthuthukisa ngokuphawulekayo ukumanzisa kwendawo yephrofayela ye-aluminium.

Umsebenzi 4: Ifilimu yokuguqulwa noma ezinye izendlalelo ezilashiwe ezakhiwe phezulu ngokuphathwa kusengaphambili zisebenza njengesendlalelo sokushintshana sobuso obuhlangene, esikhulula ukugxilisa ingqondo phakathi kwe-substrate ne-coating futhi sikhuphule amandla okubopha okuhlangana kobuso.
