Kodi Passivation of Stainless Steel ndi chiyani?

Chitsulo chosapanga dzimbiri chimayamikiridwa kwambiri chifukwa chokana dzimbiri komanso mawonekedwe ake oyera komanso amakono. Koma ngakhale zinthu zolimbazi zimapindula ndi chithandizo chowonjezera kuti chiwonjezere kukana kwa dzimbiri - njira yomwe imadziwika kutichisangalalo. Kuchiritsa kwamankhwala kumeneku kumagwira ntchito yofunika kwambiri pakukulitsa moyo wautali komanso kugwira ntchito kwachitsulo chosapanga dzimbiri m'mafakitale onse.

M'nkhaniyi, tikufotokoza chomwe passivation ndi, momwe imagwirira ntchito, chifukwa chake ili yofunika, komanso komwe imagwiritsidwa ntchito kwambiri. Monga ogulitsa zitsulo zosapanga dzimbiri,sakysteelamapereka zonse passivated ndi non-passivated zosapanga dzimbiri mankhwala ogwirizana ndi mfundo za padziko lonse.

Kodi Passivation ndi chiyani

Passivation ndi njira yamankhwala yomwe imachotsa chitsulo chaulere ndi zonyansa zina pamwamba pazitsulo zosapanga dzimbiri. Pambuyo poyeretsa, chitsulocho chimagwiritsidwa ntchito ndi oxidant wofatsa, kawirikawiri nitric acid kapena citric acid, kuti apititse patsogolo mapangidwe a oxide woonda, wowonekera pamwamba.

Chotchinga chotetezachi chimapangitsa kuti chitsulo chisamalire dzimbiri ndi dzimbiri poletsa malo omwe akugwira ntchito omwe amatsogolera ku zochitika za mankhwala ndi chilengedwe.

Passivation si zokutira kapena plating. M'malo mwake, imakulitsa chitetezo chachilengedwe cha chitsulo chosapanga dzimbiri polola kuti chromium yake ipange wosanjikiza wokhazikika wa okusayidi.

Momwe Passivation Imagwirira Ntchito

Ntchitoyi nthawi zambiri imakhala ndi njira zitatu zazikulu:

1. Kuyeretsa
   Mafuta onse, mafuta, ndi zinyalala ziyenera kuchotsedwa pogwiritsa ntchito zotsukira zamchere kapena zosungunulira. Izi zimatsimikizira kuti kusamba kwa asidi kumatha kukhudzana ndi chitsulo chopanda kanthu.

2. Chithandizo cha Kusamba kwa Acid
   Chitsulo chosapanga dzimbiricho chimamizidwa mu njira ya asidi, monga nitric kapena citric acid. Izi zimachotsa chitsulo chapamwamba ndikuyambitsa kupangika kwa wosanjikiza wa chromium oxide.

3. Kuchapira ndi Kuyanika
   Pambuyo pa kusamba kwa asidi, zinthuzo zimatsukidwa bwino ndi madzi osakaniza ndi zouma. Izi zimatsimikizira kuti palibe asidi kapena zonyansa zomwe zimatsalira pamwamba.

Chotsatira chake ndi malo osalala, okhazikika a mankhwala omwe amalimbana ndi dzimbiri ngakhale m'malo ovuta.

Chifukwa chiyani Passivation Ndi Yofunika

Ngakhale chitsulo chosapanga dzimbiri chili ndi chromium ndipo sichikhala ndi dzimbiri, kukonza makina monga kudula, kuwotcherera, kapena kupanga makina kumatha kuyambitsa chitsulo chaulere pamwamba. Tizilombo tachitsulo timeneti titha kuyambitsa dzimbiri mdera lanu ngati sizichotsedwa.

Passivation imabwezeretsa kukhulupirika kwa chitsulo pamwamba ndi:

• Kuchotsa kuipitsidwa

• Kuonjezera kukana dzimbiri

• Kupititsa patsogolo kukhazikika m'malo ovuta

• Kuthandizira ukhondo ndi miyezo yaukhondo

Kwa mafakitale monga kukonza zakudya, mankhwala, ndi zamlengalenga, kupititsa patsogolo sikungolimbikitsidwa - kumafunika nthawi zambiri.

Ntchito Zodziwika za Passivated Stainless Steel

Passivation imagwiritsidwa ntchito kwambiri m'magawo omwe amafunikira kukana kwa dzimbiri kwa nthawi yayitali komanso ukhondo. Zitsanzo zina ndi izi:

• Zida Zopangira Chakudya ndi Chakumwa
  Kupewa kuipitsidwa ndi kukula kwa bakiteriya m'malo aukhondo.

• Zida Zamankhwala ndi Zamankhwala
  Zida ndi zida za opaleshoni ziyenera kukhala zosagwira ntchito komanso zopanda dzimbiri.

• Makampani a Mafuta ndi Gasi
  Kukulitsa moyo wazinthu zomwe zimakhudzidwa ndi mankhwala, madzi amchere, kapena chinyezi chambiri.

• Kupanga Semiconductor
  Malo oyera kwambiri amachepetsa kuipitsidwa kwa tinthu m'malo ovuta.

sakysteelamapereka zida zachitsulo zosapanga dzimbiri zomwe zimakwaniritsa ASTM A967 ndi miyezo ina yapadziko lonse lapansi, zothandizira makasitomala m'mafakitale ovutawa.

Miyezo ndi Mafotokozedwe

Njira ya passivation imayendetsedwa ndi miyezo ingapo yapadziko lonse lapansi yomwe imafotokoza njira zabwino, njira zoyesera, ndi kugwiritsa ntchito mankhwala. Izi zikuphatikizapo:

• ASTM A967: Mafotokozedwe okhazikika amankhwala ophatikizika azinthu zazitsulo zosapanga dzimbiri

• ASTM A380: Maupangiri pakuyeretsa, kutsitsa, ndikudutsa

• ISO 16048: Muyezo wapadziko lonse lapansi

Miyezo iyi imawonetsetsa kuti ntchitoyi ikuchitika moyenera ndipo malo omaliza amakwaniritsa zofunikira zokana dzimbiri.

Momwe Mungadziwire Ngati Chitsulo Chosapanga chitsulo Chadutsa

Passivated zitsulo zosapanga dzimbiri siziwoneka mosiyana kwambiri ndi maso. Komabe, mayeso apadera monga mayeso a copper sulfate, kuwonetsa chinyezi chambiri, kapena kuyesa kupopera mchere kumatha kutsimikizira ngati wosanjikizawo ulipo komanso wogwira ntchito.

Mafakitale ena amafunikira chiphaso cha zinthu kuti achite.sakysteelimapereka zolembedwa zonse ndi malipoti oyesera pazinthu zomwe zasinthidwa mukafunsidwa.

Ubwino wa Passivation

Mwachidule, zopindulitsa zazikulu za zitsulo zosapanga dzimbiri zikuphatikizapo:

• Kuchulukitsa kukana kuphulika ndi dzimbiri

• Moyo wautali wautumiki wa zigawo

• Malo oyeretsera komanso aukhondo

• Kuchita bwino m'malo amankhwala kapena amchere

• Kutsata miyezo yamakampani apadziko lonse lapansi

Poikapo ndalama pazachuma, mabizinesi amachepetsa mtengo wokonza, kukonza chitetezo, ndikukulitsa kudalirika kwa zida.

Mapeto

Passivation ndi njira yofunikira pochiza zitsulo zosapanga dzimbiri, makamaka pazogwiritsa ntchito zomwe kukana dzimbiri ndi ukhondo ndizofunikira. Pochotsa zonyansa zapamtunda ndi kukulitsa wosanjikiza woteteza oxide, njirayi imalola kuti zitsulo zosapanga dzimbiri zigwire bwino ntchito yake.

Kaya mukufuna mapaipi odutsa, zopangira, akasinja, kapena zida zachikhalidwe,sakysteelatha kukupatsani mayankho omwe amakwaniritsa zomwe mukufuna komanso zomwe mukufuna kutsata makampani. Lumikizanani ndi gulu lathu kuti mudziwe zambiri za ntchito zathu zopangira zitsulo zosapanga dzimbiri komanso momwe tingathandizire kukulitsa ntchito yanu yotsatira.
