904L Zinthu Zakuthupi
Chifukwa mpweya wa 904L ndi wotsika kwambiri (0.020% pazipita), sipadzakhala mpweya wa carbide pankhani ya chithandizo cha kutentha ndi kuwotcherera.Izi zimathetsa chiopsezo cha dzimbiri intergranular kuti zambiri zimachitika pambuyo kutentha mankhwala ndi kuwotcherera.Chifukwa cha kuchuluka kwa chromium-nickel-molybdenum komanso kuwonjezeredwa kwa mkuwa, 904L imatha kuchepetsedwa ngakhale pakuchepetsa malo monga sulfuric ndi formic acid.Kuchuluka kwa nickel kumapangitsanso kuti pakhale chiwombankhanga chochepa muzochitika zogwira ntchito.Mu koyera sulfuric acid mu ndende osiyanasiyana 0 ~ 98%, kutentha ntchito 904L kungakhale mkulu monga 40 digiri Celsius.Mu asidi wa phosphoric mu ndende ya 0 ~ 85%, kukana kwake kwa dzimbiri ndikwabwino kwambiri.M'mafakitale phosphoric acid opangidwa ndi njira yonyowa, zonyansa zimakhudza kwambiri kukana kwa dzimbiri.Mwa mitundu yonse ya ma phosphoric acid, 904L imalimbana ndi dzimbiri kuposa chitsulo chosapanga dzimbiri.Mu oxidizing nitric acid wamphamvu, 904L imakhala ndi kutsika kwa dzimbiri kocheperako kuposa magiredi apamwamba kwambiri azitsulo omwe alibe molybdenum.Mu hydrochloric acid, kugwiritsa ntchito 904L kumangokhala kutsika kwa 1-2%.mu ndende iyi.Kukana kwa dzimbiri kwa 904L kuli bwino kuposa chitsulo chosapanga dzimbiri wamba.Chitsulo cha 904L chimakhala ndi kukana kwakukulu kwa dzimbiri.Kukaniza kwake kwa dzimbiri muzitsulo za chloride ndikwabwino kwambiri.Nickel yochuluka ya 904L imachepetsa kuchuluka kwa dzimbiri m'maenje ndi m'ming'alu.Zitsulo zosapanga dzimbiri zosapanga dzimbiri za austenitic zimatha kuvutitsidwa ndi dzimbiri m'malo okhala ndi chloride pamalo otentha opitilira 60 ° C, ndipo kulimbikitsa uku kumatha kuchepetsedwa powonjezera nickel muzitsulo zosapanga dzimbiri.Chifukwa cha kuchuluka kwa faifi tambala, 904L imalimbana kwambiri ndi kupsinjika kwa dzimbiri munjira za chloride, mayankho okhazikika a hydroxide ndi malo olemera a hydrogen sulfide.
904L Zida Zogwiritsira Ntchito Malo
1.Petroleum, zida za petrochemical, monga ma reactors mu zida za petrochemical, etc.
2.Kusungirako ndi zipangizo zoyendetsera sulfuric acid, monga osinthanitsa kutentha, etc.
3.The flue gas desulfurization chipangizo mu zomera mphamvu makamaka ntchito: nsanja thupi la mayamwidwe nsanja, chitoliro, shutter, mbali zamkati, makina kupopera, etc.
4.Scrubbers ndi mafani mu machitidwe a mankhwala a organic acid.
5.Zida zopangira madzi a m'nyanja, kutentha kwa madzi a m'nyanja, zida zamakampani opanga mapepala, sulfuric acid, zida za nitric acid, kupanga asidi, makampani opanga mankhwala ndi zida zina zamakina, zotengera zokakamiza, zida za chakudya.
6.Zomera zamankhwala: centrifuges, reactors, etc.
7.Chakudya chobzala: mitsuko ya msuzi wa soya, vinyo wophikira, mitsuko yamchere, zida ndi zovala.
8.904L ndi kalasi yofananira yachitsulo ya sing'anga yamphamvu yowononga ya sulfuric acid.
