1. Isisombululo kumbala weitheyiphu yobhedu
(1) Lawula ukuxinwa kwesisombululo se-asidi ngexesha lokukhetha.Kwimeko yokuhlamba i-oxide layer phezu kwendawo yobhedu edibeneyo, i-asidi ephezulu ayinayo ingqiqo.Ngokuchasene noko, ukuba ugxininiso luphezulu kakhulu, i-asidi eshiyekileyo edityaniswe kumphezulu womgca wobhedu akukho lula ukuhlanjwa, kwaye ungcoliseko lwamanzi okucoca luyakhawuleza, okukhokelela ekugxininiseni okuphezulu ngokugqithisileyo kwe-asidi eseleyo kumanzi okucoca, okwenza umcu wobhedu emva kokucoca uthambekele ngakumbi ekutshintsheni umbala.Ngoko ke, xa umisela ukuxinwa kwesisombululo se-pickling, le migaqo ilandelayo kufuneka ilandelwe: kwisiseko sokuba i-oxide layer phezu kwendawo yobhedu yobhedu inokucocwa, ukugxininiswa kufuneka kuncitshiswe kangangoko kunokwenzeka.
(2) Lawula ukuhamba kwamanzi acocekileyo.Lawula ukuhanjiswa kwamanzi acocekileyo, oko kukuthi, lawula umxholo wezinto ezinobungozi ezifana ne-chloride ion emanzini acocekileyo.Ngokuqhelekileyo, kukhuselekile ukulawula i-conductivity engaphantsi kwe-50uS / cm.
(3) Lawula ukuhanjiswa kwamanzi ashushu okucoca kunye ne-agent edlulayo.Ukunyuka kwe-conductivity yamanzi okucoca ashushu kunye ne-passivator ngokuyinhloko ivela kwi-asidi eseleyo eziswa yibhanti yobhedu eqhubayo.Ngoko ke, phantsi kweemeko zokuqinisekisa umgangatho wamanzi acocekileyo asetyenziselwa ukucoca, i-conductivity ilawulwa, oko kukuthi, i-asidi eseleyo ilawulwa.Ngokweemvavanyo ezininzi, kukhuselekile ukulawula ukuqhutyelwa kwamanzi okucoca ashushu kunye ne-passivator ukuba ibe ngaphantsi kwe-200uS / cm, ngokulandelanayo.
(4) Qinisekisa ukuba umcu wobhedu womile.Ukutywinwa okuyingxenye kuqhutyelwa kwi-coiling outlet ye-air cushion furnace, kwaye i-dehumidifier kunye ne-air conditioner isetyenziswa kwisixhobo sokutywina sendawo ukulawula umswakama kunye nobushushu ngexesha lokudibanisa umgca wobhedu ngaphakathi koluhlu oluthile.
(5) Ukugqithiswa kusetyenziswa i-arhente yokudlula.I-agent esetyenziswayo kwifektri yethu yile: i-benzotriazole, ebizwa ngokuba yi-BTA (ifomula ye-molecular: C6H5N3) njenge-agent passivating.Ukuziqhelanisa kubonakalise ukuba yinto efanelekileyo, eyongayo kwaye iyasebenza.Xa i-tape yobhedu idlula kwisisombululo se-BTA, ifilimu ye-oxide ebusweni iphendula kunye ne-BTA ukwenza i-complex enzima, ekhusela i-substrate yobhedu.
2. Isisombululo se-copper strip shear indentation
Ukuze kuthintelwe ukunyanzeliswa komphetho wokucheba, kubaluleke kakhulu ukukhetha umahluko ofanelekileyo phakathi kobubanzi bangaphandle bomese ojikelezayo kunye nendandatho ye-rubber yokuqhawula ngokobunzima kunye nobunzima bomgca;ubunzima bendandatho ye-rubber peeling ihlangabezana neemfuno zomgca wokunqunyulwa;Xa ububanzi bomgca buncinci, ubukhulu bomsele ojikelezayo kufuneka bukhethwe ngokufanelekileyo kwaye ububanzi bendandatho ye-rubber peeling kufuneka kwandiswe.
