1. Ntchito yofikira
Ntchito zazikulu zaotentha-kuviika kanasonkhezerekamapepala ali m'magawo monga magalimoto, zida zapakhomo, zomangamanga, zida zamakina, zida zamagetsi, ndi mafakitale opepuka.
2. Chifukwa chachikulu chakusanjikiza kwa zinki kugwa
Zinthu zazikulu zomwe zimapangitsa kuti zinc wosanjikiza zigwe zikuphatikizapo kupanga zopangira ndi kupanga, komanso kupanga kosagwirizana ndi kukonza.Chifukwa cha okosijeni pamtunda, mankhwala a silicon, mpweya wochuluka wa okosijeni ndi mpweya wotetezera mame mu gawo la NOF la zipangizo zopangira, mafuta osakanikirana a mpweya, kuchepa kwa hydrogen, kulowetsedwa kwa okosijeni mu ng'anjo, kutentha kochepa kwachitsulo cholowa mumphika. , kutentha kochepa kwa ng'anjo ya gawo la NOF, kutuluka kwa mafuta kosakwanira, kutsika kwa aluminiyumu mumphika wa zinki, kuthamanga kwa unit mofulumira, kuchepa kosakwanira, nthawi yochepa yokhala mumadzi a zinki, ndi zokutira wandiweyani.Kusintha kosagwirizana kumaphatikizapo kupindika kopindika kopindika, kuvala nkhungu, kukwapula, kuchotsa nkhungu kukulira kapena kung'ono kwambiri, kusowa kwamafuta opaka mafuta, komanso nthawi yayitali yogwira ntchito ya nkhungu yomwe sinakonzedwe kapena kusamalidwa.
3. Zomwe zimayambitsa dzimbiri zoyera ndizo
(1) Kusayenda bwino, kusakwanira kapena kusanja filimu makulidwe;
(2) Pamwambapa sapaka mafuta;
(3) yotsalira chinyezi padziko ozizira adagulung'undisa Mzere zitsulo;
(4) Passivation osati bwino zouma;
(5) Poyendetsa kapena kusunga, chinyezi chimabwerera kapena mvula imachepa:
(6) Nthawi yosungiramo zinthu zomalizidwa ndi yayitali kwambiri;
(7)Hot kuviika kanasonkhezereka pepalaimakhudzana kapena kusungidwa pamodzi ndi zinthu zina zowononga monga ma asidi amphamvu ndi ma alkalis.
Dzimbiri loyera limatha kusanduka madontho akuda, koma mawanga akuda sangayambitsidwe ndi dzimbiri loyera, monga mawanga akuda.
4. Nthawi yochuluka yovomerezeka yosungira
Ngati kuthira mafuta, kulongedza, kusungirako zinthu, ndi kukonza zinthu kukuchitika munthawi yake, zinthu zina zimatha kusungidwa kupitilira chaka chimodzi, koma ndi bwino kuzigwiritsa ntchito pakatha miyezi itatu.Ngati palibe odzola, nthawi ndi yaifupi kuteteza makutidwe ndi okosijeni mpweya chifukwa kusungidwa kwa nthawi yaitali.Nthawi yeniyeni yosungirako iyenera kukhazikitsidwa ndi mankhwala omwe akugwirizana ndi mankhwala enieni.
5. Mfundo Zazikulu za Kusamalira Magawo a Zinc
M'malo owononga zachilengedwe, zinki imayika dzimbiri patsogolo pazitsulo, motero imasunga maziko achitsulo.Pankhani ya kukana dzimbiri, ndi nthaka wosanjikiza kupanga zina zoteteza filimu ku youma kupewa mofulumira makutidwe ndi okosijeni mpweya, kuchepetsa mlingo dzimbiri, ndipo akhoza brushed ndi nthaka ufa utoto pa kukonza kupewa dzimbiri zitsulo ndi kuonetsetsa katundu thupi ndi Makhalidwe achitetezo a data.
6. Mfundo Zofunika Kwambiri za Passivation
Chromium trioxide passivation solution ya pepala yovimbidwa yotentha imatha kupanga filimu yooneka ngati belu.The trivalent chromium mu saturated solution passivation banja ndizovuta kusungunuka m'madzi owuma, mawonekedwe ake akuthupi siwowala, ndipo amakhala ndi mawonekedwe.Chromium ya hexavalent m'banja la passivation imasungunuka mu electrolyte yamphamvu, yomwe imatha kukhala ndi mawonekedwe a belu pamene filimu ya passivation ikukanda, ndipo imakhala ndi machiritso a filimu yooneka ngati belu.Choncho, kumlingo wakutiwakuti, filimu passivation angalepheretse nthunzi kapena yonyowa ponyowa mpweya mpweya kuti corroding yomweyo otentha-kuviika kanasonkhezereka pepala, kusewera ntchito yokonza.
7. Njira yogwiritsira ntchito kukana kwa dzimbiri
Pali njira zitatu zoyezera kukana kwa dzimbiriotentha-kuviika malata mapepala:
(1) Mayeso opopera mchere;(2) Kuyesera kozizira konyowa;(3) Kuyesa kwa dzimbiri.
