N’chifukwa chiyani zipangizo zoyeretsera mapaipi zopukutidwa zingagwiritsidwe ntchito popangira zida zoyeretsera mapaipi za chakudya?

Chinsinsi chopangira zida zopukutira mapaipi opukutidwa bwino chili mu mfundo yakuti njira yopukutira imayang'ana kwambiri
Zinthu ziwiri zofunika kwambiri pa chitetezo cha chakudya: kukula kwa tizilombo toyambitsa matenda ndi zotsalira zotsukira.
Zimapangitsa kuti mkati mwa zida za mapaipi mukhale osalala kwambiri, osasiya malo oti mabakiteriya abisale,
komanso kumawonjezera kukana dzimbiri kuti madzi azikhala oyera.
Kupezeka kwa cholumikizira chitolirochi kungatsimikizidwe kuchokera mbali zinayi.
Pewani kukula kwa tizilombo toyambitsa matenda
Chofunika kwambiri pa zolumikizira mapaipi apamwamba ndichakuti khoma lamkati liyenera kukhala losalala kwambiri,
popanda malo ooneka ngati dothi ndi mabakiteriya kuti azisonkhana.
Mapeto ake ndi okwera kwambiri: zolumikizira mapaipi zamtundu wa chakudya nthawi zambiri zimafuna kuuma kwa khoma (Ra) kosakwana 0.8 μm,
ndipo omwe amapukutidwa ndi electrolytic polishing amatha kufikira Ra ≤ 0.4 μm.
Kusalala konga galasi kumeneku kumapangitsa kuti mabakiteriya ndi dothi zisamamatire ndikukula.
Kuchotsa ngodya zofewa: Kupukuta pamodzi ndi kuwotcherera kolondola kwambiri ndi kulumikizana kumachotsa ngodya zofewa
ndi ming'alu mkati mwa mapaipi, zomwe zimaletsa zotsalira za zinthu.
2. Onetsetsani kuti kuyeretsa ndi kupha tizilombo toyambitsa matenda n'kosavuta.
Kampani yopanga chakudya imayeretsedwa mosamala (CIP) ndi kuyeretsa (SIP) tsiku lililonse,
ndipo mawonekedwe a pamwamba pa zolumikizira mapaipi ndi omwe amatsimikizira mwachindunji momwe kuyeretsa kumagwirira ntchito.
Imathandizira kuyeretsa mkati mwa malo: malo osalala kwambiri amalola kuti yankho loyeretsera ligwirizane
ndipo sambitsani zotsalira popanda choletsa, kuonetsetsa kuti palibe kuyeretsa ngodya zofewa.
Imathandizira makina oyeretsera mkati mwa malo a CIP (kuyeretsa pamalo) ndi SIP (kuyeretsa pamalo).
Zimaletsa "kumatirira pakhoma": makamaka pa zinthu zokhuthala monga mkaka ndi madzi,
Kupukuta kumatha kuletsa kupangika kwa zinthu zomatira pakhoma mkati mwa chitoliro,
kupewa kuipitsidwa kwa zinthu za batch chifukwa cha nthawi yayitali komanso kuwonongeka.
3. Kulimbitsa mphamvu yolimbana ndi dzimbiri
Zinthu zokhala ndi asidi komanso zamchere zomwe zimakhudzana ndi chakudya (monga acetic acid ndi zinthu zotsukira)
Mapaipi amatha kuwononga. Kupanga gawo losasuntha: Kupukuta nthawi zambiri kumachitika pamodzi
ndi njira zotsukira ndi kutsuka ndi asidi. Izi zimatha kupanga filimu yochuluka ya chromium-oxide pamwamba pa chitsulo chosapanga dzimbiri,
kuteteza zolumikizira mapaipi ku dzimbiri motero kuletsa chiopsezo cha kusamuka kwa zitsulo zolemera komanso kuipitsidwa ndi chakudya.
Kuchotsa zolakwika pamwamba: Kupukuta kwa makina kapena kupukuta kwa electrolytic kumatha kuchotsa mikwingwirima,
ma oxide scales, ndi tinthu tating'onoting'ono tomwe timayikidwa (monga polishing phala) pamwamba pa chitoliro,
zomwe nthawi zambiri zimakhala malo oyambira dzimbiri.
4. Zipangizo Zoyera ndi Kutsatira Malamulo
Zipangizo zoyambira za chakudya: Zipangizo zapaipi zomwe zingagwiritsidwe ntchito popukuta chakudya zimapangidwa ndi zipangizo za chakudya zokha,
Chitsulo chosapanga dzimbiri cha 304 kapena 316L, ndipo chimakwaniritsa zofunikira za dziko lonse za chiŵerengero cha zinthu zachitsulo monga GB 9684.
Njira Yotsatira: Pambuyo popukuta, amafunikanso kuchitidwa mosamala popanda mafuta
kuyeretsa kuti muchotse madontho otsala a mafuta panthawi yokonza ndikuyang'aniridwa ndi choyezera mafuta kuti muwonetsetse kuti agwira ntchito.
osadetsa chakudya.
