Nkhani

Aluminiyamu ndi chinthu chofunikira chofunikira. M'moyo watsiku ndi tsiku, nthawi zambiri timatha kuwona kugwiritsa ntchito mbiri ya aluminiyamu pomanga zitseko,mazenera, makoma a nsalu zotchinga, zokongoletsera zamkati ndi zakunja ndi zomangamanga.
Zomangamanga za aluminiyumu zomanga zimakhala ndi zofunikira zenizeni pakuyimitsidwa ndi kupanga misa, ndipo njira yolumikizira ndodo ya aluminiyamu nthawi zambiri imagwiritsidwa ntchito kuti ikwaniritse njira yabwino yopangira ndi kupanga. Lingaliro loyambirira la aluminium mbiri extrusion ndikugwiritsa ntchito kukakamiza kwina pa ndodo ya aluminiyamu mu mbiya yotulutsa kuti aloyi ya aluminiyumu ituluke mu dzenje lakufa, potero kupeza mbiri ya aluminiyamu yamawonekedwe ndi makulidwe ake. Izi extrusion processing njira ali ndi mtengo wotsika, dzuwa mkulu ndi ntchito yosavuta, ndipo amatenga gawo lalikulu mu dongosolo lamakono kupanga mafakitale. Nkhaniyi ifotokoza za njira yopangira ma profayilo a aluminium extrusion, kutilola kuti timvetsetse mozama zinthu za aluminiyamu:

1. Kupanga zinthu zopangira

Malinga ndi kuwerengetsera zikuchokera chiŵerengero chofunika mbiri aluminiyamu, zipangizo zosiyanasiyana zopangira ndi equipped.The zotayidwa ingot ndi usavutike mtima kwa kutentha zina kusungunuka, ndi kuchuluka kwa zinthu alloying amawonjezedwa ku chitsulo chosungunula zotayidwa madzi (magnesium ndi silicon zambiri anawonjezera pa dongosolo khomo ndi zenera mankhwala mizere). Mafuta a slag ndi zinyalala zomwe zimasungunuka zimachotsedwa ndi njira zoyenga zofananira.Pansi pamikhalidwe yoyenerera yoponyera, madzi osungunuka a aluminiyamu amathiridwa mu makina oponyera, atakhazikika ndikuponyedwa muzitsulo zozungulira zozungulira ndi ma diameter ndi mafotokozedwe omwe amakwaniritsa zoyembekeza.

2. Aluminiyamu ndodo extrusion

① Ikani ndodo za aluminiyamu pachoyikapo, pewani kuyandikirana kwambiri kapena kuziyika, ndipo sungani malo otetezedwa kuti zitsulo za aluminiyamu zisagubuduke kapena kugwa.

②Kutenthetsa ndodo ya aluminiyamu ndi nkhungu mu ng'anjo kuti kutentha kufika 480 ° C, ndikutentha kwa ola limodzi musanakonze;

③Ikani nkhungu m'munsi mwa chopondera, ikani ndodo ya aluminiyamu padoko la chakudya cha extruder ndikukonzekera kutulutsa;

④ Mbiri yotulutsidwa imatuluka mu dzenje lotayira, ndipo mutu wazinthu umakokedwa ndi thirakitala, ndipo kudula koyambirira kumachitika molingana ndi kutalika ndi kukula kwake.

3. Kuwongoka

Zithunzi za aluminiyamu zomwe zimakokedwa ndi extrusion nthawi zambiri sizigwirizana ndi zowongoka, zomwe zimakhudza kugwiritsa ntchito motsatira kapena kugwiritsira ntchito makina opangira makina.Mafayilo a aluminiyamu otulutsidwa amatumizidwa ku tebulo lowongoka kuti awongolere, kenako amatumizidwa kumalo omalizidwa kuti adulidwe.

4. Chithandizo chanthawi yake

Kuyika za aluminiyamu aloyi mbiri zakuthupi mu ng'anjo okalamba kutentha kwa kutentha kwina ndi kusunga kutentha kwa maola 2-3 akhoza kwambiri kusintha mawotchi aloyi aloyi mbiri, makamaka kuuma properties.Kuika odulidwa mbiri zotayidwa mu chimango zinthu, kuwatengera ku dera ukalamba, ndi kulowa ukalamba ng'anjo pamanja mankhwala okalamba. Kutentha kwa ukalamba kukafika pa 200 ℃, sungani kutentha kwa maola awiri, kenako dikirani kuti itulutsidwe; Kukalamba kukatha, kumatha kutulutsidwa mu uvuni ndikulowa mugawo lozizirira. Ikhoza kukhazikika mwachibadwa kapena mochita kupanga ndi mpweya wozizira.Panthawiyi, ntchito ya extrusion imatha, ndipo kutuluka kwa mbiri ya aluminiyamu yokhala ndi maonekedwe oyenerera ndi mawonekedwe ndi kukula kwatha.

5. Chithandizo chapamwamba

Ikani mankhwala oyenera pamwamba ngati pakufunika. Pakali pano, pali njira zingapo zodziwika bwino zapakhomo pazitseko ndi zenera: anodizing, electrophoresis, zokutira zadothi, kupopera mbewu mankhwalawa ndi fluorocarbon, etc.

Lumikizanani ndi us kuti mufunsire zina.
