Inkampani ingakwazi ukwenza ngokwezifiso ukukhiqizwa kwezitayela ezahlukahlukene zesibuko sensimbi engagqwali, wamukelekile ukuthumela i-imeyili ukuze ungibuze
1. Ebusweni bensimbi engagqwali, kukhona amadiphozithi othuli noma izinhlayiya zensimbi ezihlukahlukene eziqukethe ezinye izakhi zensimbi.Emoyeni oswakeme, amanzi ajiyile phakathi kwamadiphozi kanye nensimbi engagqwali axhumanisa kokubili ibhethri elincane, elibangela ukusabela kwe-electrochemical , ifilimu yokuvikela yonakalisiwe, ebizwa ngokuthi i-electrochemical corrosion.
2. Amajusi emvelo (njengemifino, isobho lenoodle, isikhwehlela, njll.) anamathela ebusweni bensimbi engagqwali.Lapho kukhona amanzi nomoya-mpilo, ama-asidi e-organic akhiwa, futhi ama-asidi e-organic azogqwala indawo yensimbi isikhathi eside.
3. Ingaphezulu lensimbi engagqwali linamathela ezintweni eziqukethe ama-asidi, ama-alkali nosawoti (njengamanzi ane-alkali namanzi omcako aphuma ezindongeni zokuhlobisa), okubangela ukugqwala kwendawo.
4. Emoyeni ongcolile (njengomkhathi oqukethe inani elikhulu le-sulfide, i-carbon oxide, i-nitrogen oxide), lapho kukhona amanzi ahlanganisiwe, ukwakheka kwe-sulfuric acid, i-nitric acid, i-acetic acid liquid spots, okubangela ukugqwala kwamakhemikhali. ngenhla kwezimo kungabangela ifilimu yokuzivikela endaweni yensimbi engagqwali.Ukulimala kubangela ukugqwala.
Ukumelana nokugqwala kwensimbi engagqwali ikakhulukazi kuncike ekwakhekeni kwe-alloy yayo (i-chromium, i-nickel, i-titanium, i-silicon, i-aluminium, i-manganese, njll.) kanye nesakhiwo sangaphakathi, futhi indima eyinhloko i-chromium.I-Chromium inokusimama okuphezulu kwamakhemikhali futhi ingakha ifilimu ye-passivation endaweni yensimbi ukuze ihlukanise insimbi ezweni langaphandle, ivikele i-steel plate ekubeni i-oxidized, futhi ikhulise ukumelana nokugqwala kwepuleti lensimbi.Ngemuva kokubhujiswa kwefilimu ye-passivation, ukumelana nokugqwala kuncipha.
Ipuleti lensimbi engagqwali ngokuvamile igama elivamile lepuleti lensimbi engagqwali kanye nepuleti lensimbi elimelana ne-asidi.Eyethulwe ekuqaleni kwaleli khulu leminyaka, ukuthuthukiswa kwepuleti yensimbi engagqwali kuye kwabeka izinto ezibalulekile kanye nesisekelo sobuchwepheshe sokuthuthukiswa kwezimboni zesimanje kanye nenqubekelaphambili yesayensi nezobuchwepheshe.Kunezinhlobo eziningi zamapuleti ensimbi engenasici anezakhiwo ezahlukene.Kancane kancane iye yakha izigaba eziningana ohlelweni lokuthuthukiswa.Ngokwesakhiwo, ihlukaniswe izigaba ezine: i-austenitic stainless steel, i-martensitic stainless steel (okuhlanganisa imvula eyenza insimbi engagqwali ibe lukhuni), insimbi engagqwali ye-ferritic, ne-austenitic plus ferritic duplex stainless steel.Ukwakheka kwamakhemikhali okuyinhloko noma ezinye izici zepuleti lensimbi zihlukaniswa ngepuleti lensimbi engagqwali ye-chromium, ipuleti lensimbi ye-chromium nickel, ipuleti lensimbi ye-chromium nickel molybdenum, ipuleti lensimbi engenakhabhoni ephansi, ipuleti lensimbi engagqwali le-molybdenum, ukuhlanzeka okuphezulu kwepuleti lensimbi engagqwali. , njll. Ngokuya ngezici zokusebenza nokusetshenziswa kwepuleti lensimbi, lihlukaniswe ngepuleti lensimbi engagqwali elimelana ne-nitric acid, ipuleti lensimbi engagqwali elimelana ne-sulfuric acid, ipuleti lensimbi elingagqwali elingagqwala, ipuleti lensimbi elingagqwali elingagqwali. , ipuleti lensimbi engenasici elinamandla amakhulu, njll. Ngokwezici zokusebenza zepuleti lensimbi, lihlukaniswe laba izinga lokushisa eliphansi lepuleti lensimbi engenalutho, ipuleti lensimbi engenazibuthe elingenazibuthe, ipuleti lensimbi engenalutho elisika mahhala, ipuleti lensimbi engenasici, njll. Indlela yokuhlukanisa evame ukusetshenziswa ukuhlukanisa ngokwezimpawu zesakhiwo seipuleti lensimbi, izici zokwakheka kwamakhemikhali epuleti lensimbi kanye nokuhlanganiswa kwakho kokubili.Ngokuvamile ihlukaniswa ngensimbi engagqwali ye-martensitic, i-ferritic stainless steel, i-austenitic stainless steel, i-duplex stainless steel kanye nemvula eqinisa insimbi engagqwali, njll. noma ihlukaniswe izigaba ezimbili: i-chromium stainless steel ne-nickel stainless steel.Ukusetshenziswa okubanzi Okusetshenziswayo Okujwayelekile: izishintshi zokushisa ze-pulp nephepha, okokusebenza kwemishini, okokusebenza kokudaya, okokusebenza kwefilimu, amapayipi, izinto zangaphandle zezakhiwo ezisezindaweni ezisogwini, njll.
Ipuleti lensimbi engenasici linendawo ebushelelezi, ipulasitiki ephezulu, ukuqina namandla emishini, futhi imelana nokugqwala ngama-acids, amagesi e-alkaline, izixazululo neminye imidiya.Iyinsimbi engagqwali kalula, kodwa engagqwali nhlobo.
