904L Izinto ezibonakalayo
Ngenxa yokuthi okuqukethwe kwekhabhoni engu-904L kuphansi kakhulu (ubukhulu obungu-0.020%), ngeke kube khona imvula ye-carbide esimweni sokwelashwa okuvamile kokushisa nokushisela.Lokhu kuqeda ingozi yokugqwala kwe-intergranular evame ukwenzeka ngemuva kokwelashwa kokushisa nokushisela.Ngenxa yokuqukethwe okuphezulu kwe-chromium-nickel-molybdenum kanye nokwengezwa kwethusi, i-904L ingadluliswa ngisho nasezimweni ezincishisiwe ezifana ne-sulfuric ne-formic acid.Okuqukethwe kwe-nickel ephezulu kuphinda kubangele izinga eliphansi lokugqwala esimweni esisebenzayo.Ku-sulfuric acid emsulwa ebangeni lokuhlushwa lika-0~98%, izinga lokushisa lokusebenza elingu-904L lingaba phezulu lifike ku-40 degrees Celsius.Ku-asidi ye-phosphoric ehlanzekile ebangeni lokuhlushwa lika-0~85%, ukumelana nokugqwala kwayo kuhle kakhulu.Embonini ye-phosphoric acid ekhiqizwa inqubo emanzi, ukungcola kunomthelela oqinile ekuphikiseni ukugqwala.Kuwo wonke ama-asidi e-phosphoric ahlukahlukene, i-904L ikwazi ukumelana nokugqwala kunensimbi evamile engagqwali.Ku-oxidizing nitric acid eqinile, i-904L inokumelana nokugqwala okuphansi kunamamaki ensimbi anengxubevange ephezulu engenayo i-molybdenum.Ku-hydrochloric acid, ukusetshenziswa kwe-904L kunqunyelwe ekugxilweni okuphansi kwe-1-2%.kuleli banga lokuhlushwa.Ukumelana nokugqwala kwe-904L kungcono kunokwensimbi evamile engagqwali.Insimbi engu-904L inokumelana okuphezulu nokugqwala kwe-pitting.Ukumelana kwayo nokugqwala kokugqwala ezixazululweni ze-chloride nakho kuhle kakhulu.Okuqukethwe kwe-nickel ephezulu kuka-904L kunciphisa izinga lokugqwala emigodini nasemifantwini.Izinsimbi ezivamile ze-austenitic ezingagqwali zingase zibe lula ekucindezelekeni ukugqwala endaweni ene-chloride ecebile emazingeni okushisa angaphezu kuka-60°C, futhi lokhu kuzwela kungancishiswa ngokwandisa okuqukethwe kwe-nickel yensimbi engagqwali.Ngenxa yokuqukethwe okuphezulu kwe-nickel, i-904L imelana kakhulu nokucindezeleka kokubola kokuqhekeka kuzixazululo ze-chloride, izixazululo ze-hydroxide ezigxilile kanye nezindawo ezicebile ze-hydrogen sulfide.
904L Material Application Areas
1.Uphethiloli, okokusebenza kwe-petrochemical, njengama-reactors kumishini ye-petrochemical, njll.
I-2.Impahla yokugcina kanye neyokuthutha ye-sulfuric acid, njengezishintshi zokushisa, njll.
3.Idivayisi ye-flue gas desulfurization ezitshalweni zamandla isetshenziswa kakhulu: kumzimba wombhoshongo wombhoshongo wokumuncwa, i-flue, i-shutter, izingxenye zangaphakathi, isistimu yesifutho, njll.
I-4.Scrubbers kanye nabalandeli ezinhlelweni zokwelashwa kwe-asidi ephilayo.
I-5.Amadivayisi okwelapha amanzi olwandle, abashintshi bokushisa kwamanzi olwandle, imishini yemboni yephepha, i-sulfuric acid, imishini ye-nitric acid, ukukhiqizwa kwe-asidi, imboni yemithi kanye nezinye izinto zamakhemikhali, imikhumbi yokucindezela, imishini yokudla.
6.Izitshalo zemithi: ama-centrifuges, ama-reactors, njll.
7.Ukudla kwezitshalo: izimbiza zesosi yesosi, iwayini lokupheka, izimbiza zikasawoti, izinto zokusebenza nezinto zokugqoka.
I-8.904L iyizinga lensimbi elihambisanayo lendawo egqwalayo eqinile ye-dilute sulfuric acid.
