Momwe Mungasinthire Zosapanga Dzira

Chitsulo chosapanga dzimbiri chimadziwika kwambiri chifukwa cha kukana dzimbiri, mphamvu zake, komanso moyo wake wautali. Koma ngakhale chitsulo chosapanga dzimbiri chapamwamba kwambiri chingapindule ndi mankhwala opangidwa pamwamba otchedwakungokhala cheteNgati mukudabwamomwe mungasinthire zinthu zosapanga dzimbiriNkhaniyi ikukutsogolerani zonse zomwe muyenera kudziwa—kuyambira kungokhala chete, mpaka chifukwa chake kuli kofunika, ndi malangizo a pang'onopang'ono a momwe mungachitire bwino.

Bukuli labweretsedwa kwa inu ndisakysteel, kampani yodalirika padziko lonse yogulitsa zinthu zopangidwa ndi zitsulo zosapanga dzimbiri, yomwe imapereka chithandizo chaukadaulo ndi zipangizo zapamwamba ku mafakitale padziko lonse lapansi.

Kodi Kusachitapo Kanthu Ndi Chiyani?

KusasangalalaNdi njira ya mankhwala yomwe imachotsa chitsulo chopanda zitsulo ndi zinthu zina zodetsa pamwamba pa chitsulo chosapanga dzimbiri ndipo imalimbikitsa kupanga gawo lochepa komanso loteteza la oxide. Gawo la oxide ili—makamaka chromium oxide—limagwira ntchito ngati chishango choteteza dzimbiri ndi dzimbiri.

Ngakhale chitsulo chosapanga dzimbiri chimapanga mwachibadwa gawoli likamayikidwa mumlengalenga, njira yosinthira mpweya imakulitsa ndikukhazikitsa, makamaka pambuyo pa njira zopangira monga kukonza, kuwotcherera, kupukuta, kapena kutentha.

Chifukwa Chake Kusachita Chidwi N'kofunika

Kusagwiritsa ntchito mphamvu zamagetsi sikuti ndi chinthu chongofunika kuchita—ndikofunika kwambiri m'mafakitale ambiri omwe amafuna ukhondo wapamwamba, kukana dzimbiri, komanso kulimba.

Ubwino wa chitsulo chosapanga dzimbiri chosapanga dzimbiri ndi monga:

• Kulimbitsa kukana dzimbiri

• Kuchotsa tinthu tachitsulo tomwe taikidwa

• Kuchotsa kuipitsidwa pamwamba

• Mawonekedwe abwino a pamwamba

• Nthawi yayitali yogwira ntchito m'malo ovuta

sakysteelamalimbikitsa kugwiritsa ntchito zinthu zosapanga dzimbiri makamaka pazinthu zosapanga dzimbiri zomwe zimagwiritsidwa ntchito m'makampani opanga mankhwala, zakudya, komanso mankhwala.

Kodi Muyenera Kusankha Chitsulo Chosapanga Dzimbiri Liti?

Kuchepetsa kutentha kuyenera kuganiziridwa pambuyo pa njira iliyonse yomwe ingawonetse kapena kuipitsa pamwamba pa chitsulo chosapanga dzimbiri:

• Kukonza kapena kudula

• Kuwotcherera kapena kupangira zitsulo

• Kuchotsa kapena kuchotsa chivundikiro

• Kupera kapena kupukuta

• Kugwira ntchito ndi zida zachitsulo cha kaboni

• Kukumana ndi zinthu zodetsa kapena malo okhala ndi chloride

Ngati ziwalo zanu zosapanga dzimbiri zikuwonetsa zizindikiro za kusintha kwa mtundu, kuipitsidwa, kapena kuchepa kwa kukana dzimbiri, ndi nthawi yoti muganizire za kusinthasintha kwa kutentha.

Ndi Magiredi Ati a Chitsulo Chosapanga Dzimbiri Omwe Angachotsedwe?

Magiredi ambiri achitsulo chosapanga dzimbiri amatha kukhala opanda kanthu, koma zotsatira zake zimatha kusiyana kutengera alloy.

sakysteelimapereka malangizo osankha zinthu kuti athandize makasitomala kusankha mitundu yosapanga dzimbiri yomwe imasinthasintha bwino komanso imagwira ntchito bwino m'malo owononga.

Momwe Mungapangire Chitsulo Chosapanga Dzimbiri: Njira Yoyambira ndi Gawo

Pali mitundu iwiri ikuluikulu ya zinthu zoletsa kugwiritsa ntchito mankhwala zomwe zimagwiritsidwa ntchito m'makampani:

• Yochokera ku nitric acidmayankho

• Yopangidwa ndi citric acidmayankho (osawononga chilengedwe)

Nayi chidule cha njira yogwiritsira ntchito passivation:

Gawo 1: Tsukani pamwamba

Kuyeretsa bwino ndikofunikira kwambiri musanagwiritse ntchito mankhwala. Dothi lililonse, mafuta, mafuta, kapena zotsalira zimatha kusokoneza momwe mankhwala amagwirira ntchito.

Njira zoyeretsera zikuphatikizapo:

• Zotsukira za alkaline

• Zotsukira mafuta

• Mayankho a sopo

• Kuyeretsa kwa Ultrasonic (kwa zigawo zazing'ono)

Tsukani ndi madzi oyera ndipo muume ngati pakufunika.

Gawo 2: Chotsani chidebe kapena chotsani (ngati pakufunika)

Ngati pamwamba pa chitsulo chosapanga dzimbiri pali scale yolemera, weld oxides, kapena kusintha mtundu, chitanikusakanizandondomeko isanayambe kugwedezeka.

Kusankha zinthu zotsukira kumachotsa:

• Zigawo za oxide

• Kusintha kwa mtundu wa weld

• Kuthira kwa kutentha

Kusambitsa nthawi zambiri kumachitika ndi asidi wamphamvu monga nitric-hydrofluoric acid kapena pickling paste. Mukasambitsa, tsukani bwino musanapitirire kusamba.

Gawo 3: Gwiritsani Ntchito Njira Yothetsera Kukhumudwa

Ivikeni gawo loyeretsedwalo mu bafa losagwiritsa ntchito mpweya kapena pakani yankholo pamanja.

Njira ya nitric acid:

• Kuchuluka: 20–25% nitric acid

• Kutentha: 50–70°C

• Nthawi: Mphindi 20–30

Njira yogwiritsira ntchito citric acid:

• Kuchuluka: 4–10% citric acid

• Kutentha: 40–60°C

• Nthawi: Mphindi 30–60

Gwiritsani ntchito nthawi zonsezotengera zapulasitiki kapena zosapanga dzimbirikupewa kuipitsidwa panthawi yoviika m'madzi.

Gawo 4: Tsukani Bwinobwino

Pambuyo pa nthawi yofunikira mu bafa yosambira, tsukani gawolo ndimadzi osasungunuka kapena osungunukaMadzi apampopi angasiye mchere kapena zinthu zina zosafunika.

Onetsetsani kuti zotsalira zonse za asidi zachotsedwa kwathunthu.

Gawo 5: Umitsani pamwamba

Umitsani pogwiritsa ntchito mpweya wopanikizika kapena nsalu zoyera. Pewani kuipitsa ndi zipangizo zachitsulo cha kaboni kapena nsanza zodetsedwa.

Pa ntchito zofunika kwambiri (monga mankhwala kapena mankhwala), ziwalo zina zitha kuumitsidwa m'chipinda choyera kapena chipinda chodutsa.

Zosankha: Yesani pamwamba

Zigawo zopanda mphamvu zitha kuyesedwa pogwiritsa ntchito:

• Kuyesa kwa Copper sulfate(ASTM A967): Imazindikira chitsulo chopanda

• Kuyesa kwa chipinda chonyowa kwambiri: Imaonetsa ziwalo pamalo onyowa kuti iwonetsetse kuti sizingawonongeke ndi dzimbiri

• Kuyesa kumiza m'madzi kapena kupopera mchereKuti mudziwe zambiri zokhudza kuwunika kwa dzimbiri

sakysteelimagwiritsa ntchito miyezo ya ASTM A967 ndi A380 kuti itsimikizire mtundu wa kusinthasintha kwa kutentha ndikuwonetsetsa kuti dzimbiri limatetezedwa bwino.

Malangizo Oteteza Kusachita Chidwi

• Valani zovala zodzitetezera nthawi zonse: magolovesi, magalasi, epuloni

• Gwirani ntchito pamalo opumira bwino

• Chotsani ndi kutaya asidi motsatira malamulo am'deralo

• Pewani kugwiritsa ntchito maburashi achitsulo kapena zida zomwe zingabwezeretsenso zinthu zodetsa

• Sungani ziwalo zopanda mpweya m'malo oyera komanso ouma

Ntchito Zomwe Zimafuna Chitsulo Chosapanga Dzimbiri Chopanda Pake

Passivation ndi yofunika kwambiri pazigawo zomwe zimagwiritsidwa ntchito mu:

• Zipangizo zopangira chakudya ndi zakumwa

• Makina azachipatala ndi mankhwala

• Kapangidwe ka ndege ndi ndege

• Zomera za mankhwala ndi petrochemical

• Kupanga ma semiconductor

• Kukhazikitsa zinthu za m'madzi ndi m'mphepete mwa nyanja

sakysteelimapereka zinthu zosapanga dzimbiri zokonzeka kugwiritsidwa ntchito pa ntchito zonse zomwe zili pamwambapa, zothandizidwa ndi kutsata zinthu ndi ziphaso zaubwino.

Njira Zina ndi Zochiritsira Zogwirizana Nazo Pamwamba

Kuwonjezera pa kungokhala chete, mapulojekiti ena angapindule ndi:

• Kupukuta kwamagetsi:Amachotsa gawo lochepa kwambiri la pamwamba kuti likhale loyera komanso losalala

• Kupukuta makina:Zimawonjezera kuwala kwa pamwamba ndikuchotsa kuipitsidwa

• Kusankha:Yolimba kuposa kusinthasintha, imagwiritsidwa ntchito kuyeretsa ma weld ndi ma scaling

• Zophimba zoteteza:Zophimba za Epoxy, Teflon, kapena ceramic kuti zikhale zolimba kwambiri

Uzanisakysteelkuti mudziwe njira yabwino kwambiri yogwiritsira ntchito popanga zinthu zosapanga dzimbiri.

Kutsiliza: Momwe Mungasinthire Chitsulo Chosapanga Dzimbiri Kuti Mugwire Ntchito Kwambiri

Kuchotsa zitsulo zosapanga dzimbiri ndi njira yofunika kwambiri yomaliza yomwe imawonjezera kukana kwa dzimbiri kwa chitsulo chosapanga dzimbiri mwa kuyeretsa ndi mankhwala ndikubwezeretsa chromium oxide yake yoteteza. Kaya mukugwira ntchito mumakampani ogulitsa chakudya, opanga mankhwala, kapena opanga zinthu zam'madzi, kuchotsa zitsulo zosapanga dzimbiri kumaonetsetsa kuti zikugwira ntchito bwino kwambiri m'malo ovuta.

Ndi kuyeretsa bwino, kumiza, kutsuka, ndi kuyesa, chitsulo chosapanga dzimbiri chingathe kukhala cholimba komanso cholimba ku dzimbiri. Ndipo ndi chithandizo cha ogulitsa odalirika mongasakysteel, mutha kuonetsetsa kuti zipangizo zanu zosapanga dzimbiri zakonzedwa bwino ndipo zakonzeka kugwiritsidwa ntchito.
