Momwe Mungapititsire Stainless

Chitsulo chosapanga dzimbiri chimadziwika kwambiri chifukwa chokana dzimbiri, mphamvu, komanso moyo wautali. Koma ngakhale zitsulo zosapanga dzimbiri zapamwamba zimatha kupindula ndi chithandizo chapamwamba chotchedwachisangalalo. Ngati mukudabwammene passivate zosapanga dzimbiri, nkhaniyi ikutsogolerani muzonse zomwe mukufunikira kudziwa-kuchokera ku zomwe mumakonda, chifukwa chake zili zofunika, ndi malangizo amomwe mungachitire bwino.

Bukuli labweretsedwa kwa inu ndisakysteel, ogulitsa odalirika padziko lonse lapansi opanga zitsulo zosapanga dzimbiri, omwe amapereka chithandizo chaukadaulo ndi zida zamtengo wapatali kumafakitale padziko lonse lapansi.

Kodi Passivation ndi chiyani?

Passivationndi njira yamankhwala yomwe imachotsa chitsulo chaulere ndi zonyansa zina pamwamba pa zitsulo zosapanga dzimbiri ndipo zimalimbikitsa kupanga kagawo kakang'ono, koteteza oxide. Osayidi wosanjikiza uyu—makamaka chromium okusayidi—amakhala ngati chishango polimbana ndi dzimbiri ndi dzimbiri.

Ngakhale kuti chitsulo chosapanga dzimbiri chimapanga chosanjikiza ichi chikakhala ndi mpweya, njira yodutsamo imakulitsa ndikuyikhazikitsa, makamaka pambuyo popanga njira monga makina, kuwotcherera, kugaya, kapena kutentha.

Chifukwa chiyani Passivation Ndi Yofunika

Kuchita zinthu mwachisawawa sikungosankha chabe - ndikofunika kwambiri m'mafakitale ambiri omwe amafunikira ukhondo wapamwamba, kukana dzimbiri, ndi kulimba.

Ubwino wa passivating zitsulo zosapanga dzimbiri ndi monga:

• Kupititsa patsogolo kukana dzimbiri

• Kuchotsa ophatikizidwa chitsulo particles

• Kuthetsa kuipitsidwa pamwamba

• Kuwoneka bwino kwapamwamba

• Moyo wowonjezera wautumiki m'malo ovuta

sakysteelimalimbikitsa chidwi makamaka pazinthu zosapanga dzimbiri zomwe zimagwiritsidwa ntchito m'mafakitale apanyanja, azamankhwala, azakudya, komanso mafakitale opanga mankhwala.

Kodi Muyenera Kudutsa Zitsulo Zosapanga dzimbiri liti?

Passivation iyenera kuganiziridwa pambuyo pa njira iliyonse yomwe ingavumbulutse kapena kuipitsa pamwamba pazitsulo zosapanga dzimbiri:

• Machining kapena kudula

• Kuwotcherera kapena kuwotcherera

• Kuwotcha kapena kuwotcha

• Kupera kapena kupukuta

• Kugwira ndi zida za carbon steel

• Kuwonetsedwa ndi zonyansa kapena malo okhala ndi chloride

Ngati mbali zanu zosapanga dzimbiri zikuwonetsa zizindikiro zakusinthika, kuipitsidwa, kapena kuchepa kwa dzimbiri, ndi nthawi yoti muganizire za kusinthasintha.

Ndi Maphunziro Ati Azitsulo Opanda Zitsulo Angapitirire?

Mitundu yambiri yazitsulo zosapanga dzimbiri imatha kupitsidwa, koma zotsatira zake zimatha kusiyanasiyana kutengera aloyi.

sakysteelimapereka chitsogozo chosankha zinthu zothandizira makasitomala kusankha magiredi osapanga dzimbiri omwe amayenda bwino komanso kuchita bwino m'malo owononga.

Momwe Mungadutse Chitsulo Chosapanga dzimbiri: Njira Yapang'onopang'ono

Pali mitundu iwiri ikuluikulu ya ma passivation agents omwe amagwiritsidwa ntchito m'makampani:

• Zopangidwa ndi nitric acidzothetsera

• Zopangidwa ndi citric acidmayankho (okonda zachilengedwe)

Nayi chithunzithunzi chonse cha njira yodutsamo:

Gawo 1: Yeretsani Pamwamba

Kuyeretsa bwino ndikofunikira musanayambe kupita. Dothi lililonse, mafuta, mafuta, kapena zotsalira zimatha kusokoneza momwe mankhwalawo amachitikira.

Njira zoyeretsera zikuphatikizapo:

• Mankhwala otsuka amchere

• Zotsitsa mafuta

• Zothira zotsukira

• Akupanga kuyeretsa (kwa tizigawo ting'onoting'ono)

Muzimutsuka ndi madzi aukhondo ndi kuumitsa ngati kuli kofunikira.

Gawo 2: Chotsani kapena Pickle (ngati pakufunika)

Ngati chitsulo chosapanga dzimbiri chili ndi sikelo yolemetsa, ma weld oxides, kapena ma discoloration, amachita apicklingndondomeko pamaso passivation.

Pickling amachotsa:

• Zigawo za okosijeni

• Kusintha kwa weld

• Kutentha kwamoto

Pickling imachitika ndi asidi wamphamvu ngati nitric-hydrofluoric acid kapena pickling phala. Pambuyo pickling, muzimutsuka bwinobwino musanayambe kupita ku passivation.

Gawo 3: Gwiritsani ntchito Passivation Solution

Miwirini gawo loyeretsedwalo mu bafa yodutsamo kapena gwiritsani ntchito yankho pamanja.

Njira ya nitric acid:

• Kukhazikika: 20-25% nitric acid

• Kutentha: 50-70 ° C

• Nthawi: 20-30 mphindi

Citric acid njira:

• Kukhazikika: 4-10% citric acid

• Kutentha: 40-60 ° C

• Nthawi: 30-60 mphindi

Gwiritsani ntchito nthawi zonsepulasitiki kapena zitsulo zosapanga dzimbirikupewa kuipitsidwa panthawi yomizidwa.

Gawo 4: Muzimutsuka bwino

Pambuyo pa nthawi yofunikira mu kusamba kwa passivation, muzimutsuka gawolo ndideionized kapena distilled madzi. Madzi apampopi amatha kusiya mchere kapena zosafunika.

Onetsetsani kuti zotsalira zonse za asidi zachotsedwa kwathunthu.

Khwerero 5: Yamitsani Pamwamba

Yanikani pogwiritsa ntchito mpweya woponderezedwa kapena nsalu zoyera. Pewani kuipitsidwanso ndi zida zachitsulo za kaboni kapena nsanza zakuda.

Pazofunikira kwambiri (monga zamankhwala kapena zamankhwala), zida zitha kuwumitsidwa muchipinda choyera kapena chipinda chodutsamo.

Zosankha: Yesani Pamwamba

Zigawo za Passivated zitha kuyesedwa pogwiritsa ntchito:

• Copper sulfate mayeso(ASTM A967): Imazindikira chitsulo chaulere

• Kuyeza kwa chipinda chapamwamba kwambiri: Imawonetsa magawo kumadera achinyezi kuti awonetse kukana kwa dzimbiri

• Kumiza m'madzi kapena kuyezetsa kupopera mchere: Kuti muwunikire kwambiri magwiridwe antchito a dzimbiri

sakysteelimagwiritsa ntchito miyezo ya ASTM A967 ndi A380 kuti itsimikizire mtundu wa passivation ndikuwonetsetsa kuti dzimbiri zitetezedwa bwino.

Malangizo a Chitetezo kwa Passivation

• Nthawi zonse valani zida zodzitetezera: magolovesi, magalasi, apuloni

• Gwirani ntchito pamalo olowera mpweya wabwino

• Kusalowerera ndale ndi kutaya zidulo molingana ndi malamulo am'deralo

• Pewani kugwiritsa ntchito maburashi achitsulo kapena zida zomwe zingabweretsenso zowononga

• Sungani zigawo zodutsamo pamalo aukhondo, owuma

Mapulogalamu Amene Amafuna Passivated Stainless Steel

Passivation ndiyofunikira pazinthu zomwe zimagwiritsidwa ntchito mu:

• Zida zopangira zakudya ndi zakumwa

• Makina azachipatala ndi opangira mankhwala

• Zomangamanga zamamlengalenga ndi ndege

• Zomera za Chemical ndi petrochemical

• Kupanga semiconductor

• Kuyika panyanja ndi m'mphepete mwa nyanja

sakysteelimapereka zinthu zachitsulo zosapanga dzimbiri zokonzeka kuchita zonse zomwe zili pamwambazi, mothandizidwa ndi kutsatiridwa kwa zinthu ndi ziphaso zabwino.

Njira Zina ndi Zothandizira Pamwamba

Kuphatikiza pa kuchitapo kanthu, ma projekiti ena atha kupindula ndi:

• Electropolishing:Imachotsa nsonga yopyapyala kuti ikhale yoyera kwambiri komanso yosalala

• Kupukuta kwamakina:Kumawonjezera kuwala pamwamba ndikuchotsa kuipitsidwa

• Pickling:Wamphamvu kuposa passivation, ntchito kuyeretsa welds ndi makulitsidwe

• Zovala zodzitchinjiriza:Epoxy, Teflon, kapena zokutira za ceramic kuti zikhale zolimba

Funsanisakysteelkuti mudziwe chithandizo chabwino kwambiri chapambuyo pakupanga pulogalamu yanu yosapanga dzimbiri.

Kutsiliza: Momwe Mungapititsire Chitsulo Chosapanga dzimbiri kuti Mugwire Ntchito Kwambiri

Passivation ndi njira yofunika kwambiri yomaliza yomwe imathandizira kukana kwachitsulo chosapanga dzimbiri poyeretsa ndi kubwezeretsanso wosanjikiza wake wa chromium oxide. Kaya mukugwira ntchito m'makampani azakudya, opanga mankhwala, kapena opanga zam'madzi, kutsitsa zitsulo zanu zosapanga dzimbiri kumawonetsetsa kuti zimagwira ntchito bwino m'malo ovuta.

Ndi kuyeretsa koyenera, kumizidwa, kutsuka, ndi kuyezetsa, zitsulo zosapanga dzimbiri zimatha kukwanitsa kulimba komanso kukana dzimbiri. Ndipo mothandizidwa ndi ogulitsa odalirika ngatisakysteel, mutha kuwonetsetsa kuti zida zanu zosapanga dzimbiri zakonzedwa bwino komanso zokonzeka kugwiritsidwa ntchito.
