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, exebula 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 ezacile, ephakamisa ukuthi ukudlula kubangelwa ukusebenzisana phakathi kwezinsimbi nezinto ezikhipha i-oxidizing, 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 ebolayo, ivimbele insimbi ukuthi ingahlangani nendawo edlayo, ngaleyo ndlela imise ngokuyisisekelo ukuncibilika kwensimbi futhi yakhe 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
Ngokuvamile, ukwelashwa okungaphezulu kuzoletha umbala ohlukile, kodwa ukwelashwa kwe-phosphating kungase kusekelwe 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 ye-rainbow phosphating ebusweni bezinto zensimbi, futhi isetshenziselwa ikakhulukazi ukudweba ungqimba olungezansi, ukuze kuzuzwe ukumelana nokugqwala kwe-workpiece futhi kuthuthukise ukunamathela. we-surface coating.
I-JINBAICHENG iyimboni ehamba phambili yamapayipi ensimbi e-China, Singakhiqiza futhi sinikeze ipayipi lensimbi elingenamthungo, ipayipi elishiselwe, i-saw pipe, 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
