Kodi Pickling ndi Passivation ya Stainless Steel ndi chiyani?

Chitsulo chosapanga dzimbiri chimadziwika chifukwa chosachita dzimbiri, kulimba kwake, komanso kumaliza kwake koyera. Komabe, panthawi yopanga zinthu monga kuwotcherera, kudula, ndi kupanga, pamwamba pake imatha kusokonezedwa ndi sikelo, ma oxides, kapena kuipitsidwa kwachitsulo. Kuti mubwezeretse ndikukulitsa kukana kwa dzimbiri, njira ziwiri zofunika kwambiri pambuyo pa chithandizo zimagwiritsidwa ntchito:picklingndichisangalalo.

M’nkhani ino, tiona zimene ndondomekozi zikukhudza, chifukwa chake zili zofunika, komanso zimasiyana bwanji. Kaya mukumanga, kukonza chakudya, kapena kupanga petrochemical, kumvetsetsa kunyamula ndi kusuntha ndikofunikira pakuwonetsetsa kuti zitsulo zosapanga dzimbiri zimagwira ntchito kwanthawi yayitali.

Kodi Pickling N'chiyani?

Pickling ndi njira yamankhwala yomwe imachotsazonyansa pamwambamonga weld sikelo, dzimbiri, kutentha tint, ndi oxides kuchokera pamwamba zitsulo zosapanga dzimbiri. Njirayi imagwiritsa ntchito njira ya nitric acid ndi hydrofluoric acid kuti asungunule zonyansa zomwe makina oyeretsa sangathe kuchotsa.

Momwe Pickling Amagwirira Ntchito:

• Chitsulo chosapanga dzimbiri chimathiridwa ndi asidi (nthawi zambiri ndi kumizidwa, kupaka, kapena kupopera mbewu mankhwalawa)

• Yankho lake limakumana ndi oxides ndi sikelo pamwamba pa zitsulo

• Zonyansazi zimasungunuka ndi kutsukidwa, ndikuwulula chitsulo chosapanga dzimbiri choyera, chopanda kanthu

Pickling ndi yofunikira ngati chitsulo chosapanga dzimbiri chatenthedwa kapena kuwotcherera, chifukwa kutentha kumapanga mdima wa oxide wosanjikiza womwe ukhoza kuwononga kukana kwa dzimbiri ngati sikuchotsedwa.

Kodi Passivation ndi chiyani?

Passivation ndi osiyana mankhwala ndondomeko kuti timapitiriza ndichilengedwe oxide wosanjikizapamwamba pa zitsulo zosapanga dzimbiri. Pamene pickling imachotsa zowononga, passivation imapanga filimu yochuluka ya chromium yomwe imateteza zinthu kuti zisawonongeke.

Momwe Passivation imagwirira ntchito:

• Chitsulo chosapanga dzimbiri chotsukidwa chimagwiritsidwa ntchito ndi anitric acid kapena citric acidyankho

• Asidi amachotsa chitsulo chaulere ndi zinthu zina zakunja kuchokera pamwamba

• Wowonda, yunifolomuchromium oxide wosanjikizazimapanga zokha pamaso pa mpweya kapena mpweya

Passivation sichimachotsa masikelo kapena zigawo za oxide. Choncho, nthawi zambiri amachitidwapambuyo picklingkupereka kukana dzimbiri pazipita.

Kusiyana Kwakukulu Pakati pa Pickling ndi Passivation

Ngakhale njira ziwirizi zimaphatikizira chithandizo cha asidi, zimagwira ntchito zosiyanasiyana:

• Kutolaamachotsa oxides ndi sikelo

• Passivationamachotsa chitsulo chaulere ndipo amalimbikitsa wosanjikiza woteteza oxide

• Pickling imakhala yaukali ndipo imaphatikizapo hydrofluoric acid

• Passivation ndi wofatsa ndipo nthawi zambiri amagwiritsa ntchito nitric kapena citric acid

• Pickling amasintha mawonekedwe a pamwamba; passivation sichisintha kwambiri kumaliza

Pazigawo zazitsulo zosapanga dzimbiri, njira zonse ziwiri zimagwiritsidwa ntchito motsatizana pofuna kuonetsetsa kuti pakhale malo oyera komanso osagwirizana ndi dzimbiri.

Kodi Njira Izi Zili Zofunika Liti?

Pickling ndi passivation akulimbikitsidwa mu milandu zotsatirazi:

• Pambuyokuwotchererakuchotsa kutentha kwa kutentha ndi kusinthika kwa oxide

• Kutsatiramakina kapena akupera, zomwe zingayambitse kuwonongeka kwachitsulo

• Pambuyokutentha mankhwala, kumene kukula ndi kusinthika kungapangidwe

• Zaukhondo ndi ntchito zaukhondo, kumene chiyero cha pamwamba ndi chofunika kwambiri

• In malo apanyanja kapena makemikolo, kumene kukana dzimbiri kuyenera kukonzedwa bwino

Pogwiritsa ntchitosakysteel kuzitsulo zosapanga dzimbiri komanso kugwiritsa ntchito njira zoyenera pambuyo pochiza, zida zanu zimatha nthawi yayitali komanso kuchita bwino pazovuta.

Ubwino wa Pickling ndi Passivation

Kuchita mankhwalawa kumadzetsa zabwino zingapo:

• Imabwezeretsa kukana kwathunthu kwa dzimbiri

• Kumawonjezera ukhondo pamwamba

• Imachotsa zoipitsa zozikika

• Imawonjezera moyo wachitsulo chosapanga dzimbiri

• Amakonza zinthu zopenta kapena zokutira

Kwa mafakitale monga ogulitsa mankhwala, kukonza chakudya, mafuta & gasi, pickling ndi passivation sizosankha - zimafunika kuti zisungidwe zogulitsa ndi kutsata miyezo yapadziko lonse lapansi.

Miyezo ya Makampani a Pickling ndi Passivation

Miyezo ingapo yapadziko lonse lapansi imafotokoza njira ndi malangizo:

• ASTM A380: Mchitidwe wokhazikika pakuyeretsa, kutsitsa, ndi kusuntha

• ASTM A967: Tsatanetsatane wa mankhwala passivation mankhwala

• Mtengo wa EN2516: Miyezo yaku Europe yazamlengalenga zitsulo zosapanga dzimbiri

Nthawi zonse onetsetsani kuti zinthu zanu zachitsulo zosapanga dzimbiri zikukwaniritsa miyezo imeneyi, makamaka zikagwiritsidwa ntchito m'malo ovuta kapena omwe ali pachiwopsezo chachikulu. Pasakysteel, timapereka zipangizo ndi chithandizo chaumisiri chomwe chimagwirizana ndi ndondomeko zapadziko lonse izi.

Njira Zodziwika Zogwiritsira Ntchito

Kutengera kukula kwa gawo, mawonekedwe, ndi chilengedwe, njirazi zitha kugwiritsidwa ntchito m'njira zosiyanasiyana:

• Kumiza (Thanki): Oyenera magawo ang'onoang'ono mpaka apakatikati

• Utsi Pickling: Amagwiritsidwa ntchito pazida zazikulu kapena kukhazikitsa

• Kugwiritsa Ntchito Brush: Zoyenera kuchiza komweko ngati ma weld seams

• Kuzungulira: Ntchito mapaipi kachitidwe mankhwala mkati

Kutsuka bwino ndi kusalowerera ndale pambuyo pa chithandizo ndikofunikira kuti tipewe zotsalira za asidi.

Kuganizira Zachilengedwe ndi Chitetezo

Onse pickling ndi passivation amaphatikizapo mankhwala omwe amafunikira kusamalitsa:

• Nthawi zonse valani zida zodzitetezera (PPE)

• Musamawononge zinyalala musanatayidwe

• Chitani mankhwala m'malo olowera mpweya wabwino kapena pansi pa utsi

• Tsatirani malamulo amdera lanu okhudza kugwiritsa ntchito ndi kutaya asidi

Mapeto

Pickling ndi passivation ndi njira zofunika kwambiri powonetsetsa kuti zitsulo zosapanga dzimbiri zimagwirabe ntchito kwa nthawi yayitali. Pamene pickling imatsuka ndikuchotsa sikelo, passivation imalimbitsa chitetezo cha oxide-pamodzi, amakonzekera chitsulo chosapanga dzimbiri kuti chigwiritse ntchito kwambiri.

Kusankha chitsulo chosapanga dzimbiri choyenera n'kofunika kwambiri monga kuchiza bwino. Ichi ndichifukwa chake mafakitale padziko lonse lapansi amadalirasakysteelKupereka zida zachitsulo zosapanga dzimbiri zotsimikizika, zosagwira dzimbiri limodzi ndi chithandizo chaukadaulo pakukonza ndi kupanga. Kuti mupeze mayankho odalirika pakuchita zitsulo zosapanga dzimbiri, tembenukirani kusakysteel-mnzako wodalirika wachitsulo.
