Njira zothetsera mavuto omwe amapezeka ndi tepi yamkuwa

1. Njira yothetsera kusintha kwa mtundu watepi yamkuwa

(1) Control ndende ya asidi njira pa pickling.Pankhani ya kutsuka oxide wosanjikiza pamwamba pa annealed mkuwa chingwe, mkulu asidi ndende sizipanga zomveka.M'malo mwake, ngati ndendeyo ili yochulukirapo, asidi otsalira omwe amamangiriridwa pamwamba pa mzere wamkuwa siwosavuta kutsukidwa, ndipo kuipitsidwa kwamadzi oyeretsera kumachulukitsidwa, zomwe zimapangitsa kuti asidi otsalira achuluke kwambiri. madzi oyeretsera, omwe amapangitsa kuti chingwe cha mkuwa chizitsuka chikhale chosavuta kusintha.Chifukwa chake, pozindikira kuchuluka kwa yankho la pickling, mfundo zotsatirazi ziyenera kutsatiridwa: potengera kuti wosanjikiza wa oxide pamwamba pa mzere wamkuwa ukhoza kutsukidwa, ndendeyo iyenera kuchepetsedwa momwe mungathere.

(2) Kuwongolera kayendedwe ka madzi oyera.Kuwongolera ma conductivity a madzi oyera, ndiko kuti, kuwongolera zomwe zili muzinthu zoyipa monga ma chloride ayoni m'madzi oyera.Nthawi zambiri, ndikotetezeka kuwongolera ma conductivity omwe ali pansipa 50uS/cm.

(3) Kuwongolera ma conductivity a madzi otentha oyeretsera ndi passivating wothandizira.Kuwonjezeka kwa ma conductivity a madzi otentha otentha ndi passivator makamaka amachokera ku asidi otsalira omwe amabweretsedwa ndi lamba wamkuwa wothamanga.Choncho, pansi pa chikhalidwe cha kuonetsetsa kuti madzi abwino omwe amagwiritsidwa ntchito poyeretsa, amayendetsedwa bwino, ndiye kuti, kuchuluka kwa asidi otsalira kumayendetsedwa.Malinga ndi zoyeserera zambiri, ndizotetezeka kuwongolera madutsidwe amadzi otentha otentha ndi passivator kukhala pansipa 200uS/cm, motero.

(4) Onetsetsani kuti chingwe cha mkuwa chauma.Kusindikiza pang'ono kumachitika potulutsira ng'anjo ya ng'anjo ya mpweya, ndipo dehumidifier ndi choyatsira mpweya amagwiritsidwa ntchito mu chipangizo chosindikizira chapafupi kuti azitha kuwongolera chinyezi ndi kutentha pakumangirira chingwe chamkuwa mkati mwamitundu ina.

(5) Kupititsa patsogolo pogwiritsa ntchito njira yodutsa.The passivating wothandizira ntchito fakitale yathu ndi: benzotriazole, ndicho BTA (maselo chilinganizo: C6H5N3) monga passivating wothandizira.Kuchita zatsimikizira kuti ndi yabwino, ndalama ndi zothandiza passivator.Pamene tepi yamkuwa ikudutsa mu njira ya BTA, filimu ya oxide pamtunda imakhudzidwa ndi BTA kuti ikhale yovuta kwambiri, yomwe imateteza gawo lapansi lamkuwa.

2. The njira ya mkuwa Mzere kukameta ubweya indentation

Pofuna kupewa kulowetsa m'mphepete mwameta, ndikofunikira kwambiri kusankha kusiyana koyenera pakati pa ma diameter akunja a mpeni wozungulira ndi mphete yopukutira mphira malinga ndi makulidwe ndi kuuma kwa mzere;kuuma kwa mphete yopukuta mphira kumakwaniritsa zofunikira za mzere wodulidwa;Pamene m'lifupi mwa mzerewo uli waung'ono, makulidwe a mpeni wozungulira ayenera kusankhidwa momveka bwino ndipo m'lifupi mwake mphete yopukuta mphira iyenera kuwonjezeka.
