1. Mhinduro yekuchinja kwemavaratepi yemhangura
(1) Dzora kuwanda kweasidhi mhinduro panguva yekunhonga.Munyaya yekugeza kubva kune oxide layer pamusoro peiyo annealed copper strip, yakakwira acid concentration haiite chero pfungwa.Kusiyana neizvi, kana iyo yekumisikidza yakawandisa, iyo yakasara asidhi yakanamirwa pamusoro pemhangura strip haisi nyore kusukwa, uye kusvibiswa kwemvura yekuchenesa kunowedzera, zvichikonzera kuwanda kwakanyanya kweasidhi yakasara mukati. mvura yekuchenesa, inoita kuti tambo yemhangura mushure mekuchenesa iwedzere kushanduka.Nokudaro, pakusarudza kusangana kwepickling solution, mitemo inotevera inofanira kuteverwa: pamusana pekuti oxide layer iri pamusoro pemhangura yemhangura inogona kucheneswa, kusungirirwa kunofanira kuderedzwa zvakanyanya sezvinobvira.
(2) Dzora conductivity yemvura yakachena.Dzora conductivity yemvura yakachena, ndiko kuti, kudzora zviri mukati mezvinhu zvinokuvadza zvakadai se chloride ions mumvura yakachena.Kazhinji, zvakachengeteka kudzora conductivity iri pasi pe50uS/cm.
(3) Dzora conductivity yemvura inopisa yekuchenesa uye passivating agent.Kuwedzera kweiyo conductivity yemvura inopisa yekuchenesa uye passivator inonyanya kunobva kune yakasara asidhi inounzwa nebhandi remhangura rinomhanya.Nokudaro, pasi pemamiriro ekuvimbisa hutano hwemvura yakachena inoshandiswa pakuchenesa, conductivity inodzorwa, kureva kuti, yakasara yeasidhi yakawanda inodzorwa.Zvinoenderana nezvakawanda zviedzo, zvakachengeteka kudzora conductivity yemvura inopisa yekuchenesa uye passivator kuti ive pazasi 200uS/cm, zvichiteerana.
(4) Iva nechokwadi chokuti tambo yemhangura yakaoma.Kuiswa chisimbiso kunoitwa pakuvharirwa kwechoto chemhepo cushion, uye dehumidifier uye air conditioner inoshandiswa mumudziyo wekuisa chisimbiso kudzora hunyoro uye tembiricha panguva yekukochekera tambo yemhangura mukati meimwe nhanho.
(5) Passivation uchishandisa passivating agent.Iyo passivating agent inoshandiswa mufekitori yedu ndeye: benzotriazole, iyo BTA (molecular formula: C6H5N3) seyo passivating agent.Kudzidzira kwakaratidza kuti iri nyore, ine mari uye inoshanda passivator.Kana tepi yemhangura ichipfuura nemumhinduro yeBTA, iyo oxide firimu iri pamusoro inopindirana neBTA kuti iite dense yakaoma, inodzivirira substrate yemhangura.
2. Mushonga wecopper strip shear indentation
Kuti udzivise kuvharwa kwemupendero wekucheka, zvinonyanya kukosha kusarudza kusiyana kunonzwisisika pakati pekunze kwemadhayamita emucheka wedenderedzwa uye rubber peeling ring maererano nehupamhi uye kuoma kwetambo;kuoma kwerubha peeling ring inosangana nezvinodiwa zvemucheka wekucheka;Kana hupamhi hwemutsara hudiki, hupamhi hwebanga redenderedzwa hunofanira kusarudzwa zvine musoro uye hupamhi hwerabha peeling ring inofanira kuwedzerwa.
