Aluminium Alloy Surface Chithandizo: 7 Series Aluminium Hard Anodizing

1. Njira Mwachidule

Zovuta anodizing amagwiritsa electrolyte lolingana aloyi aloyi (monga asidi sulfuric, asidi chromic, asidi oxalic, etc.) monga anode, ndipo amachita electrolysis pansi zinthu zina ndi ntchito panopa. Makulidwe a filimu yolimba ya anodized ndi 25-150um. Makanema olimba a anodized okhala ndi makulidwe a filimu osakwana 25um amagwiritsidwa ntchito kwambiri pazinthu monga makiyi a mano ndi zozungulira. Makulidwe amafilimu olimba kwambiri a anodized amafunikira kukhala 50-80um. Kusamva kuvala kapena makulidwe a filimu ya anodized kwa kutchinjiriza ndi pafupifupi 50um. Pazifukwa zina zapadera, pamafunikanso kupanga makanema olimba a anodized okhala ndi makulidwe opitilira 125um. Komabe, tisaiwale kuti thicker filimu anodized, m'munsi microhardness wake wosanjikiza akunja adzakhala, ndipo pamwamba roughness wa filimu wosanjikiza adzawonjezeka.

2. Makhalidwe a ndondomeko

1) Pamwamba kuuma aloyi zotayidwa pambuyo anodizing molimba akhoza kufika pafupifupi HV500;

2) Anodic okusayidi filimu makulidwe: 25-150 microns;

3) Kumamatira kwamphamvu, malinga ndi mawonekedwe a anodizing omwe amapangidwa ndi anodizing molimbika: 50% ya filimu yopangidwa ndi anodizing imalowa mkati mwazitsulo zotayidwa, ndipo 50% imamatira pamwamba pa aluminiyumu aloyi (kukula kwa bidirectional);

4) kutchinjiriza Good: voteji kuwonongeka angafikire 2000V;

5) Kukana kuvala bwino: Kwazitsulo za aluminiyamu zomwe zili ndi mkuwa zosakwana 2%, chiwerengero chachikulu cha kuvala ndi 3.5mg / 1000 rpm. Mlozera wovala wa ma aloyi ena onse sayenera kupitirira 1.5mg/1000 rpm.

6) Zopanda poizoni komanso zopanda vuto kwa thupi la munthu. The electrochemical ndondomeko anodizing filimu mankhwala ntchito kupanga ndi alibe vuto, kotero kuti zofunika kuteteza chilengedwe mu processing makina ambiri mafakitale, mankhwala ena ntchito zolimba anodized zotayidwa aloyi m'malo zitsulo zosapanga dzimbiri, kupopera mbewu mankhwalawa chikhalidwe, molimba chromium plating ndi njira zina.

3. Minda yofunsira

Kutentha kwamphamvu kumakhala koyenera makamaka kumadera omwe amafunikira kukana kwamphamvu kwambiri, kukana kutentha, komanso zinthu zabwino zotchinjiriza za aluminiyamu ndi zida za aluminiyamu. Monga masilindala osiyanasiyana, ma pistoni, mavavu, ma silinda, mayendedwe, zipinda zonyamula katundu za ndege, ndodo zopendekeka ndi njanji zowongolera, zida zamagetsi zamagetsi, zonyamulira nthunzi, makina omasuka a flatbed, magiya ndi ma buffers, etc. Traditional electroplating ya hard chromium ili ndi mawonekedwe otsika mtengo, koma chilema cha filimuyi ndikuti pamene makulidwe a filimuyo ndi aakulu, zimakhudza kulolerana kwa makina. kutopa mphamvu ya aluminiyamu ndi zitsulo zotayidwa.
