Ⅰ- I-AcidUkukha
1.-Incazelo yeI-Acid-Pickling: Ama-Acids asetshenziselwa ukususa isikali se-iron oxide ngamakhemikhali endaweni ethile, izinga lokushisa, kanye nesivinini, okubizwa ngokuthi i-picling.
2.- I-Acid-Ukuhlukaniswa kwe-Pickling: Ngokohlobo lwe-asidi, ihlukaniswe yaba yi-sulfuric acid pickling, i-hydrochloric acid pickling, i-nitric acid pickling, ne-hydrofluoric acid pickling.Imidiya ehlukene kufanele ikhethwe ukuze ikhethwe ngokusekelwe ezintweni zensimbi, njengokukhetha insimbi ye-carbon ne-sulfuric acid ne-hydrochloric acid, noma insimbi engagqwali exutshwe nengxube ye-nitric acid ne-hydrofluoric acid.
Ngokusho kokuma kwensimbi, ihlukaniswe yaba yi-wire pickling, i-forging pickling, i-steel plate pickling, i-strip pickling, njll.
Ngokuhambisana nohlobo lwemishini yokukhetha, ihlukaniswe yaba ukucotshwa kwamathangi, ukucosha kancane okuqhubekayo, ukuqoqwa okuqhubekayo okuphelele, nokuqoqwa kombhoshongo.
3.- Umgomo wokukhetha i-asidi: Ukukhetha i-asidi kuyinqubo yokukhipha izikali ze-iron oxide endaweni yensimbi kusetshenziswa izindlela zamakhemikhali, yingakho kubizwa nangokuthi i-chemical acid pickling.Izikali ze-iron oxide (Fe203, Fe304, Fe0) ezakhiwe phezu kwamapayipi ensimbi ziyi-oxide eyisisekelo engancibiliki emanzini.Uma zicwiliswa kusisombululo se-asidi noma zifuthwe ngesisombululo se-asidi ngaphezulu, le oxide eyisisekelo ingabhekana nochungechunge lwezinguquko zamakhemikhali nge-asidi.
Ngenxa yokuxega, ukuvuleka, nokuqhekeka kwemvelo yesikali se-oxide ebusweni bensimbi ye-carbon structural noma i-low alloy steel, kuhlanganiswe nokugoba okuphindaphindiwe kwesikali se-oxide kanye nensimbi yomugqa ngesikhathi sokuqondisa, ukuqondisa ukuqina, kanye nokuhamba pickling line, lezi imifantu pore ukwanda futhi andise.Ngakho-ke, isixazululo se-asidi sihlangana nesikali se-oxide ngamakhemikhali futhi siphinde sihlangane nensimbi engaphansi kwensimbi ngemifantu nezimbotshana.Okusho ukuthi, ekuqaleni kokugeza i-asidi, ukusabela kwamakhemikhali amathathu phakathi kwesikali se-iron oxide kanye nensimbi yensimbi nesisombululo se-asidi kwenziwa kanyekanye Izikali ze-iron oxide zibhekana nokusabela kwamakhemikhali nge-asidi futhi ziyancibilika (ukuhlakazeka) Insimbi yensimbi isabela ne-asidi khiqiza igesi ye-hydrogen, ecwecwa ngomshini isikali se-oxide (umphumela wokucwecwa kwemishini) I-athomu ye-athomu ekhiqiziwe inciphisa ama-iron oxides abe ama-oxide ayinsimbi ajwayele ukusabela kwe-asidi, bese isabela nama-asidi azosuswa (ukuncipha).
Ⅱ-Passivation/Ayisebenzi/Yenziwa kungasebenzi
1.- Umgomo wokwenza i-passivation: Indlela yokudlulisa ingachazwa ngethiyori yefilimu emincane, ephakamisa ukuthi ukudlula kubangelwa ukusebenzisana phakathi kwezinsimbi nezinto ezigcobayo, okukhiqiza ifilimu encane kakhulu, eminyene, embozwe kahle, futhi ekhangisiwe ngokuqinile endaweni yensimbi.Lolu ngqimba lwefilimu lukhona njengesigaba esizimele, ngokuvamile inhlanganisela yezinsimbi ezixutshwe ne-oxidized.Idlala indima ekuhlukaniseni ngokuphelele insimbi endaweni egqwalayo, ivimbele insimbi ukuthi ingahlangani nendawo edlayo, ngaleyo ndlela imise ukuncibilika kwensimbi futhi yenze isimo sokungenzi lutho ukuze kuzuzwe umphumela wokunqanda ukugqwala.
2.- Izinzuzo ze-passivation:
1) Uma kuqhathaniswa nezindlela zokuvala zendabuko ezingokomzimba, ukwelashwa kwe-passivation kunesici sokungakhulisi neze ukushuba kwesiqeshana sokusebenza nokushintsha umbala, ukuthuthukisa ukunemba kanye nenani elengeziwe lomkhiqizo, okwenza ukusebenza kube lula;
2) Ngenxa yesimo esingasasebenzi senqubo yokudlula, i-ejenti yokudlula ingangezwa ngokuphindaphindiwe futhi isetshenziswe, okuholela ekuphileni okude kanye nezindleko zokonga kakhulu.
I-3) I-Passivation ikhuthaza ukwakheka kwefilimu ye-oksijini yesakhiwo samangqamuzana endaweni yensimbi, ehlangene futhi ezinzile ekusebenzeni, futhi inomphumela wokuzilungisa emoyeni ngesikhathi esifanayo.Ngakho-ke, uma kuqhathaniswa nendlela yendabuko yokugcoba uwoyela we-antirust, ifilimu ye-passivation eyakhiwe yi-passivation izinzile futhi imelana nokugqwala.Iningi lemiphumela yokushaja kungqimba lwe-oxide ihlobene ngokuqondile noma ngokungaqondile nenqubo ye-oxidation eshisayo.Ezingeni lokushisa lika-800-1250℃, inqubo ye-oxidation eshisayo esebenzisa umoya-mpilo owomile, umoya-mpilo omanzi, noma umhwamuko wamanzi unezigaba ezintathu eziqhubekayo.Okokuqala, umoya-mpilo osemkhathini wemvelo ungena ongqimbeni lwe-oxide okhiqizwayo, bese umoya-mpilo usakazeka ngaphakathi nge-silicon dioxide.Uma ifinyelela kusixhumi esibonakalayo se-Si02-Si, isabela ne-silicon ukwenza i-silicon dioxide entsha.Ngale ndlela, inqubo eqhubekayo yokusabela kokusabalalisa kwe-oksijini entry kwenzeka, okubangela ukuthi i-silicon eseduze nesixhumi esibonakalayo ukuthi iguqule ngokuqhubekayo ibe i-silica, futhi ungqimba lwe-oxide lukhulela ngaphakathi kwe-silicon wafer ngesilinganiso esithile.
Ⅲ- I-Phosphating
Ukwelashwa kwe-Phosphating ukusabela kwamakhemikhali okwenza ungqimba lwefilimu (ifilimu ye-phosphating) ebusweni. Inqubo yokwelapha i-phosphating isetshenziswa ikakhulukazi ezindaweni zensimbi, ngenhloso yokuhlinzeka ngefilimu evikelayo ukuze ihlukanise insimbi emoyeni futhi ivimbele ukugqwala;Ingasetshenziswa futhi njenge-primer yeminye imikhiqizo ngaphambi kokudweba.Ngalolu ngqimba lwefilimu ye-phosphating, lungathuthukisa ukunamathela nokumelana nokugqwala kwesendlalelo sepende, sithuthukise izakhiwo zokuhlobisa, futhi senze ubuso bensimbi bubukeke buhle kakhulu.Ingase futhi idlale indima yokugcoba kwezinye izinqubo zokusebenza ezibandayo zensimbi.
Ngemuva kokwelashwa kwe-phosphating, i-workpiece ngeke i-oxidize noma igxume isikhathi eside, ngakho-ke ukusetshenziswa kokwelashwa kwe-phosphating kubanzi kakhulu futhi kuyinqubo yokwelashwa kwensimbi evame ukusetshenziswa.Iya ngokuya isetshenziswa ezimbonini ezinjengezezimoto, imikhumbi, kanye nokukhiqizwa kwemishini.
1.- Ukuhlukaniswa nokusetshenziswa kwe-phosphating
Imvamisa, ukwelashwa okungaphezulu kuzokwethula umbala ohlukile, kepha ukwelashwa kwe-phosphating kungasuselwa ezidingweni zangempela ngokusebenzisa ama-ejenti ahlukene we-phosphating ukwethula imibala ehlukene.Yingakho sivame ukubona ukwelashwa kwe-phosphating ngokumpunga, umbala, noma omnyama.
I-iron phosphating: ngemuva kwe-phosphating, ingaphezulu lizobonisa umbala we-rainbow kanye nohlaza okwesibhakabhaka, ngakho-ke kubizwa nangokuthi umbala we-phosphorus.Isixazululo se-phosphating ikakhulukazi sisebenzisa i-molybdate njengento eluhlaza, ezokwakha ifilimu yombala we-rainbow phosphating ebusweni bezinto zensimbi, futhi isetshenziselwa ikakhulukazi ukupenda ungqimba olungezansi, ukuze kuzuzwe ukumelana nokugqwala kwe-workpiece futhi kuthuthukiswe ukunamathela. we-surface coating.
I-JINBAICHENG iyimboni ehamba phambili yamapayipi ensimbi e-China, Singakhiqiza futhi sinikeze ipayipi lensimbi elingenamthungo, ipayipi elishiselwe, ipayipi lokusaha, ipayipi le-gi elinobuso be-Acid-Pickling, Passivation, kanye nePhosphating.Sihlinzeka ngensizakalo yokuthunga ngokwezifiso futhi sizokunikeza isixazululo esingcono kakhulu samaphrojekthi akho.Xhumana nathi ukuze uthole intengo engcono kakhulu:https://www.sdjbcmetal.com/steel-pipe-series/ i-imeyili:jinbaichengmetal@gmail.com noma WhatsApp athttps://wa.me/18854809715
