I-QN1803 (304D) ipuleti lensimbi engagqwali
1. Incazelo:
Ibanga lomkhiqizo omusha i-QN1803 liwumkhiqizo wokuqala we-nitrogen ephezulu emhlabeni, ukumelana nokugqwala okuphezulu, umkhiqizo wensimbi engagqwali we-nickel osindisa i-austenitic.
Ngokwesisekelo sokuqinisekisa ukumelana nokugqwala okulingana nensimbi engagqwali engama-304, amandla ezinto ezibonakalayo ayathuthukiswa, kanye nezinto ezibonakalayo.
izindleko ziyancipha, okwenza kube engabizi kakhulu futhi kuqhudelane kakhulu emakethe kune-304 insimbi engagqwali.
Izici zokwakheka komkhiqizo omusha: i-nitrogen ephezulu (≥2000ppm), i-chromium ephezulu (≥18%), i-nickel emaphakathi (~3.0%) kanye nekhopha ephezulu (≥1.5%).
Ngepulatifomu yedijithali ye-R&D yedijithali ye-Thermo-Calc isoftware yokubala yesigaba se-thermodynamic kanye nokuhlaziya idatha yokuhlola, ukulungisa
Izakhi ze-alloying zengxenye ngayinye yesigaba azithuthukisi kuphela ukumelana nokugqwala komkhiqizo, kodwa futhi zenza amandla okukhiqiza we-QN1803
izikhathi ezingaphezu kwe-1.3 kune-304.
I-QN1803 inezici ezilandelayo:
1) i-pitting corrosion okulingana ne-PREN=Cr+3.3Mo+30N-Mn ingaphezulu kuka-19.0, okungenani enokumelana nokugqwala okufanayo okungu-304
insimbi engagqwali.
2) ukumelana nokugqwala okufanayo ku-dilute hydrochloric acid, hlanza i-sulfuric acid, i-acetic acid + usawoti nezinye izindawo kungcono kakhulu
304 insimbi engagqwali.
3) ukumelana nokugqwala kungcono kuno-304 esimweni sokusetshenziswa sangempela ngemuva kokugoba, ukugxiviza, isimo esiqinile nokunye ukwakheka okubandayo.
4) amandla okukhiqiza angaphezu kuka-1.3 izikhathi ezingaphezu kuka-304 zensimbi engagqwali, futhi inobude obungekho ngaphansi kuka-45%. Gqoka ukumelana futhi
ukusebenza kokukhathala kungcono kune-304 insimbi engagqwali.
5) ukusebenza kahle kokushisela, amandla ngemuva kokushisela aphakeme kunalawo ensimbi engagqwali engama-304, futhi ukumelana nokugqwala
uma kuqhathaniswa naleyo yensimbi engagqwali engu-304.

6. Ukulayishwa Kwesitsha:
7.Uhlelo lokusebenza:
➢Imboni yezokwakha: ukwakha uphahla, izindonga, ama-purlin, izingxenye zesakhiwo ezithwala umthwalo, njll.:
➢Izicabha zehardware namafasitela: njengamadrayini aphansi, amahinji, amahinji, ama-slide rails, njll.;
➢Amapayipi ashiselwe okuhlobisa: njengocingo, imigoqo yeziteshi, izitebhisi ezizihambelayo, amafasitela okuvikela, njll.;
➢Amapayipi ashiselwe ezimbonini: njengamapayipi egesi, amapayipi endle ezimbonini;
➢Iziqukathi zamathangi embonini: njengeziqukathi zokuthutha amanzi, imibhoshongo yokususa igesi;
➢ Impahla yokuzalanisa: njengomkhombe wokupha izingulube, umkhombe wokukhuluphalisa kabili;
➢ Izinsiza zikamasipala: njengamadokodo amabhasi, izindawo zokukhucululwa kwendle.
