Isingeniso sempahla yensimbi engagqwali:
Insimbi engagqwali impahla nayo izoba nokugqwala.Izinto zensimbi engagqwali yitemu elivamile lempahla.Ngokuvamile kunezinhlobo ezintathu zezinto ezisetshenziswayo zezikulufu zensimbi engagqwali: impahla engu-201, impahla engu-304, impahla engu-316 kanye nokusebenza kwe-anti-corrosion ngu-316>304>201.Intengo nayo ihlukile.Intengo ye-316 insimbi engagqwali iphezulu kakhulu.Ngokuvamile isetshenziswa ezindaweni ezine-acidic kanye nokugqwala kwamanzi olwandle.Amanzi olwandle aqukethe i-acidic physique, futhi izidingo zezinto ezibonakalayo ziphezulu kakhulu.
Isimiso sokugqwala sensimbi engagqwali:
1. Ingaphezulu lensimbi engagqwali liqoqe uthuli oluqukethe ezinye izakhi zensimbi noma okunamathiselwe kwezinhlayiya zensimbi zangaphandle.Emoyeni oswakeme, amanzi ajiyile phakathi kokunamathiselwe nensimbi engagqwali axhuma kokubili ukwenza ibhethri elincane, eliqala ukusabela kwe-electrochemical.Ifilimu yokuzivikela yonakele, ebizwa ngokuthi i-electrochemical corrosion.
2. Ingaphezulu lensimbi engagqwali linamathela kujusi wemvelo (njengekhabe, imifino, isobho lenoodle, isikhwehlela, njll.), eyenza iasidi ephilayo lapho kukhona amanzi nomoya-mpilo, kanti iasidi ephilayo izogqwalisa ingaphezulu lensimbi ukuze isikhathi eside.
3. Ingaphezulu lensimbi engagqwali linamathela ekuqukethe ama-asidi, ama-alkali, nezinto zikasawoti (njengamanzi ane-alkaline namanzi omcako afafaza ezindongeni zokuhlobisa), okubangela ukugqwala kwendawo.
4. Emoyeni ongcolile (njengomkhathi oqukethe inani elikhulu le-sulfide, i-carbon oxide, ne-nitrogen oxide), uzokwakha i-sulfuric acid, i-nitric acid, namachashaza oketshezi lwe-acetic acid lapho uhlangana namanzi ajiyile, okubangela ukugqwala kwamakhemikhali.
Izindlela:
1. Ingaphezulu lensimbi engagqwali yokuhlobisa kufanele ihlanzwe futhi ikhuhlwe njalo ukuze kukhishwe okunamathiselwe futhi kuqedwe izici zangaphandle ezibangela ukuguqulwa.
2. Ukwakheka kwamakhemikhali kwamanye amapayipi ensimbi engagqwali emakethe akukwazi ukuhlangabezana namazinga ahambisanayo kazwelonke futhi akukwazi ukuhlangabezana nezidingo zezinto ezibonakalayo ze-SUS304.Ngakho-ke, ukugqwala kuzophinde kubangele, okudinga ukuthi abasebenzisi bakhethe imikhiqizo kubakhiqizi abahloniphekile ngokucophelela.
3. Uma sisetshenziswa ezindaweni ezisogwini lolwandle, kufanele sikhethe impahla yensimbi engagqwali engu-316 engamelana nokugqwala kwamanzi olwandle.
