Chitsulo cholimbana ndi dzimbiri ndi chitsulo chapadera cha alloy chomwe chimalimbana bwino kwambiri ndi dzimbiri powonjezera ma aloyi osagwirizana ndi dzimbiri monga mkuwa, faifi tambala, ndi chromium.

Chitsulo choterechi chimatha kukana kukokoloka kwa zinthu zosiyanasiyana zowononga kwambiri.

Kukana kwake kwa dzimbiri ndi nthawi 2-8 kuposa chitsulo wamba mpweya. Pamene nthawi yogwiritsira ntchito ikuwonjezeka, kukana kwa dzimbiri kumawonekera kwambiri.

Chitsulo chosagwira ndi dzimbiri ndi mtundu wachitsulo chomwe chimateteza ku dzimbiri, kupangitsa kuti chisachite dzimbiri.

chitsulo chosagwira dzimbiri

Zitsulo zosapanga dzimbirindi ma aloyi opangidwa ndi chitsulo okhala ndi 10.5% chromium yocheperako, yomwe ndi yokwanira kuteteza dzimbiri m'mikhalidwe yotentha ya chipinda.

Kuphatikiza pa kukana bwino kwa dzimbiri, chitsulo chosapanga dzimbiri chimakhalanso ndi makina abwino kwambiri, katundu wowotcherera, ndi zina zambiri.

Choncho, chimagwiritsidwa ntchito mu makampani petrochemical, uinjiniya m'madzi, makampani mankhwala, chilengedwe chitetezo zomangamanga, zomangamanga mphamvu ndi madera ena kupanga zipangizo zosiyanasiyana, mapaipi, akasinja yosungirako, zigawo zikuluzikulu, etc. kuonetsetsa ntchito yaitali khola ndi chitetezo cha zida.

Pa Marichi 11, 2024, European Commission idapereka chilengezo chonena kuti idapereka chigamulo choyamba choletsa kutaya kwadzuwa pakulowa kwa dzuwa pa Corrosion Resistant Steels yochokera ku China, akuti ngati njira zoletsa kutaya zichotsedwa, kutayidwa kwa zinthuzo. kukhudzidwa ndipo kuwonongeka kwa kutaya komwe kwachitika ku mafakitale a EU kupitilira kapena kuchitikanso, chifukwa chake adaganiza kuti apitilize kusunga ntchito zoletsa kutaya zinthu pazachuma zaku China zomwe zikukhudzidwa.

Misonkho yotsutsana ndi kutaya ndi 17.2% mpaka 27.9%.

Nthawi yofufuzira pakutaya pankhaniyi ikuchokera pa Januware 1, 2022 mpaka Disembala 31, 2022, ndipo nthawi yofufuza zowonongeka ikuchokera pa Januware 1, 2019 mpaka kumapeto kwa nthawi yofufuza zotaya.

Pa Disembala 9, 2016, bungwe la European Commission lidayambitsa kafukufuku woletsa kutaya zitsulo zolimbana ndi dzimbiri zochokera ku China.

Pa February 8, 2018, European Commission idapereka chigamulo chomaliza choletsa kutaya zitsulo zolimbana ndi dzimbiri zochokera ku China.

Pa february 8, 2023, European Commission idakhazikitsa kafukufuku woyamba woletsa kutaya kwa dzuwa pakulowa kwa chitsulo cholimbana ndi dzimbiri chochokera ku China.

Pali mitundu yosiyanasiyana ya zitsulo zosagwira dzimbiri, zomwe zimapangidwa molingana ndi malo osiyanasiyana ogwiritsira ntchito komanso zofunikira zokana dzimbiri.

Nazi zitsanzo zachitsulo zomwe zimalimbana ndi dzimbiri:

304s ndimbale yachitsulo chosapanga dzimbiri:Mtunduwu uli ndi kukana bwino kwa dzimbiri komanso magwiridwe antchito, ndipo umagwiritsidwa ntchito kwambiri m'mafakitale azakudya, zamankhwala, zamankhwala ndi zina.

316 mbale yachitsulo chosapanga dzimbiri:Mo element imawonjezedwa pamaziko a 304 kuti ipititse patsogolo kukana kwa dzimbiri komanso kutentha kwambiri, ndipo ndiyoyenera malo owononga omwe ali ndi kutentha kwambiri komanso kuthamanga kwambiri.

06Cr19Ni10:Ichi ndi mbale yachitsulo yosapanga dzimbiri ya austenitic yomwe zigawo zake zazikulu ndi Cr, Ni, C, ndi zina zotero. Zimakhala ndi kukana bwino kwa dzimbiri ndi ntchito yokonza ndipo zimagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala, mafuta a petroleum ndi madera ena.

022Cr17Ni12Mo2:Iyi ndi mbale yachitsulo yosapanga dzimbiri yosapanga dzimbiri yopangidwa ndi Cr, Ni, Mo, ndi zina. Ili ndi kukana kwambiri kutentha ndipo imagwiritsidwa ntchito kwambiri mu petrochemical, organic chemical, ndege, ndege ndi zina.

00Cr17Ni14Mo2:Ichi ndi mbale yachitsulo chosapanga dzimbiri chopangidwa ndi Cr, Ni, Mo, etc. Ili ndi kukana kwabwino kwa dzimbiri komanso kukana kuvala ndipo imagwiritsidwa ntchito popanga zida zopangira mankhwala, petroleum ndi madera ena.
