Mzere wamkuwa wophimbidwandi chinthu chachitsulo chokhala ndi malata pamwamba pa chingwe chamkuwa. Kapangidwe ka mizere yamkuwa yopangidwa ndi zitini imagawidwa m'magawo atatu: kupangira mankhwala, plating ndi pambuyo pochiritsa.
Malinga ndi njira zosiyanasiyana zokutira malata, zimatha kugawidwa m'ma electroplating ndi plating yotentha. Pali kusiyana pakati pa chingwe chamkuwa chopangidwa ndi electroplated ndi dip yotenthamkuwa wamkuwam'mbali zambiri.
I. Mfundo ya ndondomeko
1) Electroplating tinning: Imagwiritsa ntchito mfundo ya electrolysis kugwiritsa ntchitomkuwamonga cathode ndi malata ngati anode. Mu njira ya electroplating yomwe ili ndi ayoni a malata, ayoni amachepetsedwa ndikuyikidwa pamwamba pa mzere wamkuwa kuti apange wosanjikiza wa malata kudzera mukuchita kwanthawi yayitali.
2) Kuviika kotentha: Ndiko kumizamkuwam'madzi osungunuka a malata. Pazikhalidwe zina za kutentha ndi nthawi, madzi a malata amadzimadzi amakhudzidwa ndi thupi ndi makemikolo ndi pamwamba pa mzere wamkuwa kupanga wosanjikiza wa malata pamwamba pa mzere wamkuwa.
II. Makhalidwe okutikira:
1) Kuphimba kufanana
A) Electroplating tinning: Kufanana kwa zokutira ndikwabwino, ndipo kumatha kupanga kusanjikiza kofananako komanso kosakhwima pamwamba pamkuwa. Makamaka pamizere yamkuwa yokhala ndi mawonekedwe ovuta komanso malo osagwirizana, imathanso kuphimba bwino, yomwe ili yoyenera pazithunzi zogwiritsira ntchito zomwe zili ndi zofunika kwambiri kuti zikhale zofanana.
B) Kuviika kotentha: Kufanana kwa zokutira kumakhala kocheperako, ndipo makulidwe opaka osagwirizana amatha kuchitika pamakona ndi m'mphepete mwamkuwa. Komabe, nthawi zina zomwe zofunikira pakubisala mofanana sizikhala zovuta kwambiri, zotsatira zake zimakhala zochepa.
2) Kupaka makulidwe:
A) Electroplating tinning: Kukhuthala kwa zokutira kumakhala kochepa kwambiri, nthawi zambiri kumakhala pakati pa ma microns ochepa ndi ma microns makumi, ndipo kumatha kuyendetsedwa bwino malinga ndi zosowa zenizeni.
B) Dip dip tinning: Kukhuthala kwake kumakhala kokulirapo, nthawi zambiri kumakhala pakati pa ma microns makumi angapo ndi mazana a ma microns, omwe amatha kuletsa dzimbiri komanso kukana kuvala.zingwe zamkuwa, koma sizingakhale zoyenera kwa mapulogalamu ena omwe ali ndi malire okhwima pa makulidwe.
III. Kupanga bwino
1) Electroplating malata plating: Njira yopanga ndi yovuta, imafuna njira zingapo monga pre-mankhwala, electroplating, ndi post-treatment. Kuthamanga kwapang'onopang'ono kumakhala kochepa ndipo sikuli koyenera kupanga zazikulu komanso zogwira mtima kwambiri. Komabe, pazosowa zamagulu ang'onoang'ono komanso zosinthidwa makonda, plating plating plating imakhala yabwino kusinthika.
2) Kupaka malata otentha: Njira yopangira ndiyosavuta. The malata plating ndondomeko akhoza anamaliza ndi kumiza ndimkuwamu madzi amchere. Kuthamanga kwapangidwe kumathamanga ndipo kumatha kukwaniritsa zosowa za kupanga kwakukulu.
IV. Mphamvu yolumikizana:
1) Electroplating malata plating: Mphamvu yolumikizana pakati pa zokutira ndi zitsulomkuwagawo lapansi ndi lamphamvu. Izi zili choncho chifukwa ma tani amapanga mgwirizano wa mankhwala ndi ma atomu pamwamba pa mzere wamkuwa pansi pa mphamvu ya magetsi panthawi ya electroplating, zomwe zimapangitsa kuti zokutirazo zikhale zovuta kugwa5.
2) Kuyika kwa malata otentha: Mphamvu yolumikizira imakhalanso yabwino, koma nthawi zina, chifukwa cha zovuta zomwe zimachitika pakati pa madzi a malata ndi pamwamba pa madzi.mkuwapanthawi yopaka kutentha, ma pores ang'onoang'ono kapena zolakwika zimatha kuwoneka, zomwe zimakhudza mphamvu yomangira. Komabe, pambuyo pa chithandizo choyenera, mphamvu yomangirira ya plating yotentha yotentha imathanso kukwaniritsa zofunikira pamagwiritsidwe ambiri.
V. Kulimbana ndi dzimbiri:
1) Electroplating tinning: Chifukwa cha zokutira zopyapyala, kukana kwake kwa dzimbiri kumakhala kofooka. Komabe, ngati njira ya electroplating ikuyendetsedwa bwino komanso yoyenera pambuyo pa chithandizo, monga passivation, ikuchitika, kukana kwa dzimbiri.mkuwa wamkuwazithanso kuwongoleredwa
2) Hot-dip tinning: Chophimbacho ndi chokhuthala, chomwe chingapereke chitetezo cholimba cha kutu kumkuwa. M'malo ovuta kwambiri achilengedwe, monga madera achinyezi komanso owononga mpweya, kukana kwa dzimbiri, mwayi wokana kutentha kwa dip.mkuwa wamkuwandizowonekera kwambiri5.
VI. Mtengo
1) Electroplating tinning: Ndalama zogulira zida ndizochepa, koma chifukwa chazovuta zopanga, zimawononga magetsi ochulukirapo ndi ma reagents amankhwala, ndipo zimakhala ndi zofunika kwambiri pamapangidwe ndi ogwira ntchito, motero mtengo wake ndi wokwera kwambiri.
2) Hot-dip tinning: Ndalama zogulira zida ndi zazikulu, ndipo ng'anjo zotentha kwambiri ndi zida zina ziyenera kumangidwa, koma kupanga kwake ndikosavuta komanso kugwiritsa ntchito zinthu zopangira ndizochepa, kotero mtengo wagawo ukhoza kukhala wotsika. kupanga kwakukulu.
Kusankha amkuwa wamkuwazoyenera pakugwiritsa ntchito kwanu kumafuna kulingalira mozama pazinthu zingapo monga mphamvu zamagetsi, zida zamakina, kukana dzimbiri, kupanga, mtengo ndi kuteteza chilengedwe. Malinga ndi zosowa zenizeni, yesani ubwino ndi kuipa kwa mbali zonse ndikusankha zoyenera kwambirimkuwa wamkuwakuonetsetsa kuti ntchito ndi khalidwe la mankhwala.
