Kwimveliso yemizi-mveliso, zimbini iintlobo zonyango oluphezulu: Inkqubo yonyango lwenkqubo yekhemikhali kunye nenkqubo yonyango lwekhemikhali. Ukumnyama komgangatho wentsimbi engenanto yinkqubo eqhelekileyo esetyenzisiweyo kunyango lweekhemikhali.
Umgaqo: ngonyango lweekhemikhali, ungqimba lwefilimu ye-oxide luveliswa kumphezulu wensimbi, kwaye unyango lomhlaba luphunyezwa kwifilimu ye-oxide. Umgaqo osetyenzisiweyo kule nkqubo yonyango lomphezulu kukwenza ifilimu yesidi-fiso kwisinyithi phantsi kwesenzo sokusebenza, esinokukhetha isinyithi ngokudibana ngqo nemeko yangaphandle.
Iindlela eziqhelekileyo zokwenza intsimbi engenasitali ihamba ngolu hlobo lulandelayo:
ICandelo loku-1: I-Acid Doloring Indlela
(1) indlela yedichromate. Ukuntywila kwentsimbi engenasitayile kwisisombululo se-sodium sodium sedichichromate kwaye sikhuthaze ngokucokisekileyo imizuzu engama-20 ukuya kwengama-30 ukwenza ifilimu emnyama ye-oxide. Susa kwaye upholile, emva koko uhlambe ngamanzi.
. Inkqubo yokutshintsha kombala wale fildi yefilimu ivela ekukhanyeni ukuya kumnyama. Xa itshintsha ukusuka ekukhanyiseni oluhlaza okwesibhakabhaka kwi-blue (okanye emnyama emnyama), ixesha lokuphumla liyi-0.5-1 kuphela. Ukuba le nqaku ilungele impumelelo, iya kubuyela emdaka kwaye inokususwa kuphela kwaye iphinde isuswe.
2. Indlela yokungaqhelekanga inokufumana ifilimu emnyama emnyama, ekufuneka ikhutshwe nge-Aqua Grejia ngaphambi kwe-oxidation
I-3. I-Alkaline Oxiotion. I-Alkaline Oxidation sisisombululo esilungiselelwe i-sodium hydroxide, kunye nexesha le-oxidation yemizuzu eli-10-15. Ifilimu emnyama ye-oxide inesidima sokunxiba kakuhle kwaye ayifuni unyango. Ixesha lokutshiza ityuwa liphakathi kweeyure ezingama-600-800. Unokugcina umgangatho obalaseleyo wentsimbi engenasimo ngaphandle kwerm.
ICandelo le-2: Indlela ye-Electrolytitititic
Ukulungiselela kwesisombululo: (20-40G / L Dictionate, i-10-40g / L Manganese / i-10 ukuya kwi-10 ukuya kwi-10 ukuya kwi-10 ukuya kwi-10 ukuya kwi-10 ukuya kwi-LOR / L / L / L / L / L / L / L / L / L / L / L / L / L / L / L / L / L / L / L / L / L / L / L / L / L / L / L / L / I / L / L / L / L / I / L / L / L. Ifilimu enemibala ifakwe kwi-10% ye-HCL yesisombululo kwi-25c imizuzu emi-5, kwaye kwakungekho tshintsho lungatshisiyo okanye ukuqaqanjelwa kwefilimu yangaphakathi yefilimu, ebonisa ukunganyangeki kwefilimu yefilimu. Emva kwe-electrolysis, nge-1CR17 intsimbi engenasitali ityhafile ngokukhawuleza, emva koko ilukhuni ukufumana ifilimu emnyama ye-oxide enemibala engapheliyo, i-elasticy, kunye nobunzima obuthile. Iimpawu ziyinkqubo elula, ikhawulezile isantya esibonakalayo, isiphumo esifanelekileyo semibala, kunye nokunganyangeki okuhle. Ifanelekile ukuba iphantsi kwempatho yokuphathwa kweendawo ezahlukeneyo ezingenanto kwaye ke inexabiso elifanelekileyo elifanelekileyo.
ICandelo 3: I-QPQ SURDE YOCULO
Iqhutywa kwizixhobo ezikhethekileyo, umaleko wefilimu uqinile kwaye unesidima esihle sokunganyangeki; Nangona kunjalo, ngenxa yokuba inyani yentsimbi engenalo intsimbi, ngakumbi intsimbi engenasibala, ayinawo amandla okuthintela okufanayo njengaphambi kwe-QPQ. Isizathu kukuba umxholo we-chromium kumphezulu wensimbi engazinzanga ingonakalisi. Kuba kwinkqubo yangaphambili ye-QPQ, yinkqubo ye-nitrication, i-carbon kunye nomxholo we-nitrogen uya kungena, ukubangela umonakalo kwisakhiwo somphezulu. Kulula ukurhuqa, ityuwa itshiza ihlwempuza kuphela kwiyure ezimbalwa. Ngenxa yobuthathaka, ukusebenzisa kwayo kubaluleke kakhulu.
