Ukukhiqizwa nokusetshenziswa kokuhlanzeka (ibanga lokudla) ipayipi lensimbi engagqwali
1. Ukuhlaziywa komhlaba kwezinsimbi zepayipi ezingagqwali
Kokubili i-Auger Electron Spectroscopy (AES) kanye nezindlela ze-X-ray Spectroscopy (SPS) zingasetshenziswa ukuhlaziya ingaphezulu lensimbi engenasici ukuthola ukumelana nokugqwala kwezindawo zokuqina kwensimbi engaphakathi. Ububanzi bokuhlaziywa kwendlela ye-AES buncane kakhulu, obungaba ngaphansi kwe-20mm, kanye nendima yalo yokuqala ukuhlukanisa phakathi kwezinto. Ukuhlaziywa kwendlela ye-XPS kucishe kube yi-10μm, efanelekile ukucacisa amakhemikhali e-organic wezinto eziseduzane.
Ama-AES kanye ne-XPS Detators asetshenziselwa ukwenza isithwebuli ebusweni bomhlaba kanye neplate ebilisiwe engu-316 yensimbi ebiyelwe umoya. Kuphetha ngokuthi ukujula okujwayelekile okuphelele kokuhlaziywa komhlaba kwepayipi lensimbi engenasici kungu-15mm, kanye nesendlalelo sokwelashwa esifanelekile siyakhonjiswa. Ukwakheka, ubukhulu kanye nekhono layo lokulwa nokulwa nokuwohloka, njll.
Ngokusho kwencazelo, insimbi ephansi ye-alloy ine-chromium ephezulu ne-nickel, kanti abanye baqukethe i-molybdenum (njenge-316L00rm17NO27NO2), i-titanium, njll. Ukuphikiswa kokugqwala ngenxa yezimpawu zokulungiswa kwe-chromium-rich arner ungqimba, ungqimba lokuhamba ngokuvamile luyi-3-5nm obukhulu, noma obukhulu njengezendlalelo eziyi-15 zama-molecule. Isendlalelo sokuhamba sikhiqizwa phakathi nenqubo yonke yokusabela komoya-ukusabela, lapho i-chromium ne-iron i-oxidiated ngomoya. Uma ungqimba lokuhamba lulimele, kuzokhiqizwa ungqimba olusha lokudlula ngokushesha noma umgomo weseli laseGalvanic uzokhiqizwa ngokushesha. Amapuleti ensimbi engagqwali azothola ukugqwala okujulile kwe-crevice kanye nokugqwala kwengcindezelo. Ukumelana nokugqwala kwesendlalelo sokuhamba kuhlobene nokuqukethwe kwamanzi kwezakhi eziqukethwe epuletini lensimbi engenasici. Isibonelo, i-chromium ephezulu, i-nickel, futhi i-molybdenum ingakhuphula umehluko ongaba khona wamandla abophayo wesendlalelo sokushisa kanye nokuphikiswa kokugqwala kwesendlalelo sokuvutha. Ibuye ibuye ihlobene nokwelashwa kwezindawo zensimbi ngamapayipi ensimbi engagqwali kanye nokusetshenziswa kwezinto zeHydrodynamic.

1 Ungqimba ophrintiwe wesendlalelo sokuhamba uqhubeka kuphela ngensimbi. Ezimweni eziningi, isendlalelo sokuhamba sabhujiswa kuphela engxenyeni yendawo yokuhamba ?? insimbi engenacala. Umphumela we-etching uncike esizukulwaneni sezimbobo ezinhle noma ama-dents. I-etching encane efana ne-etching engasatshalaliswa njalo ebusweni bezinto ezingavuthiwe ibizwa ngokuthi iCrevice Corrision. Izinga lokugqwala kwama-crevice liyakhuphuka ngokushisa okwandayo nokukhuphuka ngokuhlushwa okwandayo. Isixazululo ukusebenzisa i-carbon ephansi ye-ultra noma i-carbon engenacala (njenge-316 amalitha angama-304 amalitha)
2. Ngesikhathi sokukhiqiza kanye ne-welding yensimbi ye-auntenitic engenacala, i-blunt warping ungqimba ngaphezulu kwensimbi engenasici ilonakala kalula. Lapho izinga lokushisa lokushisa kanye nesivinini sokushisa ngesikhathi sokukhiqiza kanye ne-welding zisezingeni lokushisa lensimbi elingagqwali (cishe i-425-815 ° C) Kulokhu, izinga lokuphazamiseka kwekhabhoni ku-aucen likhulu kunaleso se-chromium, futhi i-chromium ayikwazi ukunxephezela i-chromium elahlekile ngenxa yokwakhiwa kwe-chramium carbide emngceleni we-christal mandery emngceleni we-christal. Ngenxa yalokhu, okuqukethwe kwe-chromium komngcele we-crystal lokusanhlamvu kukhuphuka ukuhlaziya i-chromium carbide futhi kunciphise uma kuhlangana nezinto zokwakha, kuzodala ukugcwala kwebhethri elisha elishajela. Ukugqwala kungukuphela kobuso bezinhlamvu zekristalu, ezingena ngokushesha ingaphakathi ukuze kwakhiwe ukugqwala okwenzeka phakathi. Amapayipi ensimbi engagqwali agqamile kakhulu e-Welding kagesi.
I-3. Ukuqhekeka kokugqwala kwengcindezi: Kungumphumela obanzi we-Static Data Ground Terress kanye nokuguguleka okubangela ukuqhekeka kanye nezinto ezibonakalayo zensimbi eziqhakazayo. Imvelo yemvelo ebangela ukuqhekeka kokugqwayiza kwengcindezelo nokubhujiswa kuvame ukuba yinkimbinkimbi kakhulu. Akukona nje kuphela ukucindezelwa komhlaba, kepha futhi nokucindezelwa komhlaba kanye nokuxineka kwangaphakathi okubangelwa ukukhiqiza, ukufudumala kukagesi noma ukujuluka nokufutheka ngezinto zensimbi.
3. Ukuxhumeka phakathi kokwelashwa komhlaba wangaphakathi nangaphandle kwensimbi nokuphikiswa kokugqwala kokufakwa kwamapayipi wensimbi engagqwali
Izendlalelo zangaphakathi nangaphandle zensimbi ezingenasici (ezifana nokudonswa kwamakhemikhali, ukugaya nokuphoqelela) zinezendlalelo zokwelashwa ezinhle kakhulu, ezinokuphikiswa okuqinile kokugqwala. Izendlalelo zangaphakathi nangaphandle zinobushelelezi obuphakeme, futhi kunokunamathelisa okuncane kakhulu okubonakalayo, okuzuzisa ukumelana nokukhulisa. I-liquid ephakathi nendawo enobunzima obuphezulu igcinwa ku-tube, okungcono kokuhlanza, ikakhulukazi embonini yezemithi.
1.. I-Chemical Polishing ukuxazulula inkinga. Ngalesi sikhathi, ingaphezulu le-tube lifeza izinqubo ezimbili eziphambeneyo, okungukuthi, ukuguqulwa nokuncibilika kwesendlalelo sensimbi engenasici (kufaka phakathi i-mucosa eminyene). Lokhu kungenxa yokuthi indinganiso ye-densalfication kanye ne-presivation yama-prororrical protor kanye nokuphumula ngaphandle kwesendlalelo esingaphandle kwehlukile, futhi i-anodic oxidation incibilika. Ngenxa yezimo ezahlukahlukene zokwakheka kwamafilimu kanye nokudlula kwe-surce surcopic concopic kanye nezingxenye ze-anode, kanye nokuchithwa kosawoti wensimbi, ukugcwala usawoti wensimbi endaweni ye-anode kuyaqhubeka ukwanda, kwakha i-mucosa yokumelana ne-viscous ephezulu ebusweni. Umehluko wobukhulu befilimu e-convex kanye nezingxenye zemikhuhlane baphumela ekujuleni kwamanje kwesendlalelo se-anodized surface, isikhathi esifushane sokuncibilika esincibilikayo, futhi esikhathini esifushane sokuncibilika sedlula umgomo ovelele wezomnotho wangaphandle, futhi ungadlula ubushelelezi obuphezulu raṣ0.2-0.4μM. Futhi ngaphansi kwalolu hlobo lomphumela, okuqukethwe kwamanzi kwe-chromium kwepayipi kuyanda, kanye nekhono lokulwa nokugqwala lokuhamba ngensimbi engenasici
Ungayiqonda kanjani ikhwalithi ye-polishing kufanele ihambisane neresiphi eyimfihlo ye-Lithium Battery Electrolyte, Inani lokushisa, isikhathi se-plug-in, i-general yensimbi yensimbi yensimbi. Ukwehluleka ukwazi kahle lobu buchwepheshe empeleni kuzokuqeda ubushelelezi bepayipi. Uma indlela ye-electrolysis ineveline kakhulu, kuzoba nezindawo eziningi ze-convex ne-concave. Ikhwalithi yangempela kumele ibe ngezobuchwepheshe futhi izindleko ziphakeme kakhulu.
2 Lapha, ukuthatha ukugaya okwenziwe ngomshini okujikelezayo njengesibonelo, imishini yokugaya imishini ilula, amandla kanye nokugaya kanye nemishini yokugaya okuthuthukile kunama-disc alula, amandla kanye nokugaya, kanye ne-wax yokugaya okuthuthukile. I-disc yendwangu nendwangu eyenziwe ngenhlayiya enhle yesihlabathi ehlelwe kabusha ibuye ibheke emuva naphambilini elingaphandle lepayipi langaphakathi nangaphandle lepayipi kaningi, futhi umkhawulo ungafinyelela ra ≤ 0.2-0.4μμ
Uma kuqhathaniswa nokugaya kwe-electrolytic, ukugaya okwenziwe ngomshini kusetshenziswa kabanzi ngenxa yemishini yayo elula, okuqukethwe okuphansi kwezobuchwepheshe, ukubamba okulula, izindleko eziphansi zokusebenzisa, akukho monakalo kwishubhu. Kodwa-ke, ukumelana nokugqwala kwesendlalelo sokuphrinta esingaphezulu kungcono kakhulu kune-electropolishing.
Isici esikhudlwana seshubhu elibandayo elibandayo yi-Hard State, okungukuthi, inkomba yokuvutha inkulu kakhulu, futhi ayilungele ukuvutha nokugoba. Ukukhuluma ngokuqinile, akuhlangabezani ne-National Induna Engajwayelekile, ngakho-ke kufanele kwenziwe i-therkosolidication (ukujula).

Isithando somlilo esikhanyayo: Isakhiwo esiyisihluthulelo siqukethe ithangi le-muff-stack elisezingeni eliphakeme le-muffle, kanye nendlela yokushisa enezintambo eziphakeme zokushisa amazinga okushisa ahlelwe nhlangothi zombili nasezinhlangothini eziphansi. I-ammonia encibilike igesi isetshenziswa njengoSteam wesondlo kanye nohlelo olujikelezayo lwamanzi okupholisa amanzi. Amapayipi afakwe kule ndlela yokwelashwa kokushisa akudingeki ukuthi akhiwe futhi adlule, aqinisekisa ukushelela kwezingqimba zangaphakathi nangaphandle komhlaba futhi zigwema ukungalingani okuncane kwepayipi ebusweni obubangelwa ukukha indawo. Ngoba lezi zinto ezingekho emthethweni ezingenzayo zizokwenza ukuthi ipayipi libe lifishane ngokucaciswa kobushelelezi bendawo yamapayipi okuthuthwa kwenhlalo. Ngakho-ke, khetha umoya okhanyayo okhanyayo. Hangao tech's Isithando Esibonakalayo Sokuvikela igesi ekhanyayo Ihlangabezana ngokugcwele izidingo zakho, hhayi kuphela ukusebenza kahle kwe-Airtight, kepha futhi nokusebenza okuphezulu nokulondolozwa kwamandla. Uma kuqhathaniswa nohlobo olufanayo lwemishini, lungagcina cishe ama-20% -30% wokusetshenziswa kwamandla.
