Isimiso esiyisisekelo sokususa uthuli lwe-nozzle nge-sulphurization ukuhlukanisa izinhlayiya zothuli emoyeni noma entuthwini.
Okokuqala, izinhlayiya zothuli zimanziswa ngamanzi ukuze kwandiswe usayizi wezinhlayiya kanye namandla adonsela phansi athile. Izinhlayiya zothuli zizobe sezihlukana nomoya noma igesi yomoya ongcolile. Uma umlomo wokukhipha i-sulfurization uphukile, sidinga ukuwususa umlomo womoya. Umsebenzi othize umi kanje:
1) izingxenye ezilindile noma izingxenye ezisele kufanele zigcinwe kahle: Abaphakeli abajwayelekile baneziphakeji ezikhethekile kanye namalebula, okungukuthi, kufanele zibekwe ngaphandle kokusetshenziswa. Ama-nozzles asusiwe kufanele acwiliswe emafutheni (uphethiloli, uwoyela wedizili, njll.) ukuvimbela ukugqwala.
2) Uma kukhona iphutha mayelana nomlomo wokususa i-sulfurization osetshenziswayo, ukuhlolwa komlomo kudinga ukuhlukaniswa. Abasebenzisi kumele basebenzise amathuluzi akhethekile noma amathuluzi afanele ukuhlakaza nokuhlakaza ubudlelwano bomhlangano isinyathelo ngesinyathelo.
3) Ama-nozzle asusiwe kufanele afakwe ngokushesha ebhentshini lokuhlola i-nozzle esikhundleni sanoma yikuphi ukwelashwa. Ngokwengcindezi yokusebenza enqunyiwe, izici zokugeleza, ukutholwa kwe-engeli yokufutha kanye nokuqashelwa kwekhwalithi yokufutha kuyenziwa. Lokhu kungaxazululwa lapho kulungiswa inkinga.
I-nozzle yokususa i-sulfurization ivele ngaphansi kwezidingo zokuvikelwa kwemvelo. Inhloso eyinhloko yomkhiqizo ukukhipha i-sulphur igesi njalonjalo. Lokhu kwenza ukukhiqizwa kwezimboni kube nobungane nemvelo. Izakhiwo zamakhemikhali ze-nozzle yokususa i-sulfur zichazwe ngezansi, futhi silangazelela ukukusiza.
Ukumelana nokuxinana kwe-oxidation kwama-nozzles akhipha i-sulphur
Uma izinto ze-silicon carbide zishiswa kufikela kuma-degree angu-1300 emoyeni, ungqimba oluvikelayo lwe-silicon dioxide luyakhiwa phezu kobuso be-silicon carbide crystal. Ukuqina kongqimba oluvikelayo kuvimbela i-silicon carbide yangaphakathi ukuthi iqhubeke noku-oxidation. Lokhu kwenza i-silicon carbide ibe nokumelana okuhle noku-oxidation. Uma izinga lokushisa lingaphezu kuka-1900K (1627 C), ifilimu elivikelayo le-silica liyabhujiswa. Kuleli qophelo, uku-oxidation kwe-silicon carbide kuyaqina. Ngakho-ke, i-1900K iyizinga lokushisa lokusebenza eliphakeme kakhulu le-silicon carbide emoyeni oxidation.
Ukumelana ne-acid ne-alkaline kwama-nozzles akhipha i-sulphur:
Esicini sokumelana ne-asidi, ukumelana ne-alkali kanye ne-oxidation, umsebenzi wefilimu evikela i-silicon dioxide ungathuthukisa ukumelana ne-asidi kanye nokumelana ne-alkali kwe-silicon carbide.
