Isingeniso somsebenzi we-Metal Coatings kuma-Terminal Blocks
Imisebenzi yokumboza ingahlukaniswa kakhulu ngezigaba ezintathu: imisebenzi yokuvikela, imisebenzi kagesi, kanye nemisebenzi yemishini/yenqubo.
1. Umsebenzi wokuvikela (ukumelana nokugqwala nokuqina)
Lona umsebenzi oyisisekelo nobaluleke kakhulu wokumboza.
- Ukuvimbela ukugqwala kwe-substrate: I-Copper ingakha i-copper oxide noma i-copper sulfide uma ivezwa emoyeni omanzi noma ezindaweni eziqukethe isibabule. Lawa ma-compounds anomoya ophansi kakhulu futhi angakha ungqimba oluvikelayo, okuholela ekwandeni okungazelelwe kokumelana nokuxhumana, okungabangela ukwehluleka kokushisa noma ngisho nokujikeleza. Isembozo sisebenza "njengesithiyo" esiqinile, esihlukanisa i-substrate endaweni yangaphandle.
- Ukuthuthukisa ukuzivumelanisa nezimo kwemvelo: Ezindaweni ezahlukene zokusetshenziswa (njengokushisa okuphezulu kanye nomswakama, i-salt spray, kanye namagesi amakhemikhali ezimboni), ukukhetha i-coating efanele kungathuthukisa kakhulu ukumelana nokugqwala kwama-terminals. Isibonelo, i-nickel noma i-chromium plating isebenza kahle kakhulu ezindaweni zezimboni ezinzima.
2. Umsebenzi kagesi (ukuqinisekisa ukusebenza kahle kokuqhuba)
- Ukuqinisa nokunciphisa ukumelana nokuxhumana: Ukunikeza indawo engenamandla okumelana: izembozo ezifana ne-tin nesiliva zinokuqhuba okuhle futhi azikwazi ukushiswa yi-oxidation, okunikeza indlela eqinile nenganamandla okumelana nokugeleza kwamanje.
- Amafilimu e-oxide aphula ukuvikela: Izembozo eziningi (ikakhulukazi i-tin ne-tin alloys) zithambile. Lapho ama-terminals egoqekile noma izikulufo ziqinisiwe, isembozo singadlula ekuguqukeni nasekugelezeni okuncane, sibhoboze ucingo noma ifilimu ye-oxide ebusweni be-terminal yokuhlangana, okuvumela ukuthintana ngqo kwensimbi nensimbi (okungukuthi, "ukuthintana kwensimbi"), okunciphisa kakhulu ukumelana kokuthintana.
- Ukugcina ukuzinza kukagesi isikhathi eside: Izimbozo zekhwalithi ephezulu zingalondoloza isimo sazo sobuso ngokuhamba kwesikhathi, zivimbele ukuqhekeka kokumelana okubangelwa ukugqwala futhi ziqinisekise ukuxhumana kukagesi okuzinzile kuyo yonke impilo yomkhiqizo.
Imisebenzi Yomshini Nokucubungula
Thuthukisa Ukushibilika: Kuma-terminal adinga ukushibilika (njenge-PCB terminals), ukushibilika kubalulekile. Ukushibilika kwe-alloy ye-tin kanye ne-tin-lead kunamandla okushibilika amahle kakhulu, okuqinisekisa ukuthi amalunga okushibilika ayashesha, aqinile, futhi athembekile. Ukushibilika kwethusi elimsulwa kuyawohloka kakhulu ngemva kokushibilika kobuso, futhi ukushibilika kunikeza indawo eshibilika isikhathi eside.
Thuthukisa Ukumelana Nokuguguleka: Ama-terminal avame ukwenza imisebenzi efana nokuxhuma nokukhipha i-plug noma ukuqinisa ngezikulufo ngesikhathi sokusetshenziswa. Izembozo eziqinile ezifana ne-nickel noma i-chrome plating zingakhuphula ngempumelelo ubulukhuni bendawo, zinciphise ukuguguleka kokufakwa okuphindaphindiwe, futhi zandise impilo yesevisi. Ziphinde zivimbele ukuvezwa kwezinto ezingaphansi ezigqwalayo ngenxa yokuguguleka.
Nciphisa Ukungqubuzana Komphezulu Wokuthintana: Ama-plating athile (njenge-tin) anezakhiwo zokuzigcoba ngokwawo, okwenza ukuqinisa izikulufo kube bushelelezi, i-torque izinze kakhudlwana, futhi kunciphisa ukuguguleka kokungqubuzana phakathi kwezinsimbi.
