Insimbi engagqwali
Ngokwencazelo ye-GB/T20878-2007, izici eziyinhloko zensimbi engagqwali, ukumelana nokugqwala, nokuqukethwe kwe-chromium okungenani okungu-10.5%, okuqukethwe kwekhabhoni okuphezulu akungaphezu kuka-1.2%.
Insimbi Engagqwali (Insimbi Engagqwali) imfushane ngensimbi engagqwali engamelana ne-asidi, umoya, isitimu, amanzi kanye nokunye okubuthaka kokugqwala okuphakathi noma insimbi engagqwali;Futhi i-chemical corrosion resistant medium (acid, alkali, salt and other chemical etching) ukugqwala kwensimbi okubizwa nge-acid resistant steel.
Ngenxa yomehluko ekwakhekeni kwamakhemikhali kokubili futhi ukumelana kwazo nokugqwala kwehlukile, insimbi engagqwali evamile ngokuvamile ayimelani nokugqwala kwemithombo yamakhemikhali, futhi insimbi emelana ne-asidi ngokuvamile ayinakho ukugqwala.Igama elithi "insimbi engagqwali" alibhekiseli nje ohlotsheni lwensimbi engagqwali, kodwa lisho izinhlobo ezingaphezu kwekhulu zensimbi engagqwali yezimboni, ukuthuthukiswa kwensimbi engagqwali ngayinye kunokusebenza okuhle endaweni yayo ethile yesicelo.Isihluthulelo sempumelelo siwukuthola kuqala injongo, bese unquma uhlobo olufanele lwensimbi.Ngokuvamile kunezinhlobo eziyisithupha kuphela zensimbi ezihlobene nensimu yesicelo sokwakhiwa kwesakhiwo.Wonke aqukethe amaphesenti angu-17 kuya kwangu-22 e-chromium, futhi izinsimbi ezingcono nazo zine-nickel.Ukwengezwa kwe-molybdenum kungathuthukisa ukugqwala komkhathi, ikakhulukazi ukumelana nokugqwala komkhathi oqukethe i-chloride.
Ngokuvamile, ubulukhuni bensimbi engagqwali buphakeme kune-aluminium alloy, izindleko zensimbi engagqwali ziphakeme kune-aluminium alloy.
