Okuthandwayo okushisayo kwe-dip galvanized strip steel
Inqubo Yokukhiqiza
Isigaba I
Ikhoyili yonke ye-strip steel izovuthwa futhi ingcoliswe ukuze kufinyelele indawo ekhanyayo futhi ehlanzekile.
Isigaba II
1.I-Hot-dip galvanizing: ngemva kokukhetha, ihlanzwa nge-ammonium chloride noma i-zinc chloride isixazululo samanzi noma i-ammonium chloride ne-zinc chloride exutshwe nethangi lesisombululo samanzi.Bese ithunyelwa ethangini lediphu elishisayo ukuze lifakwe uthayela.
2.I-Hot galvanizing: ngemva kokukhetha, ihlanzwa kubhavu we-ammonium chloride noma i-zinc chloride ye-aqueous solution noma i-ammonium chloride ne-zinc chloride exutshwe nesisombululo esinamanzi, bese ithunyelwa kubhavu wokugcoba emva kwesithando somlilo esiqhubekayo sokuvuthwa.
3.I-galvanizing eqondile: ngemva kokukhetha, ithunyelwa esithandweni somlilo esiqhubekayo bese ingena ethangini elifaka uthayela ukuze livuthe.
Isigaba III
Ngemuva kokuthi insimbi ye-strip isiphehliwe, kufanele ihlanganiswe futhi ifakwe endaweni yokugcina.Isendlalelo esinothayela akufanele sibe ngaphansi kuka-50g/m2 ngokwezidingo zekhasimende, futhi noma iyiphi isampula akufanele ibe ngaphansi kuka-48g/m2.
Insimbi eyi-galvanized strip ngokuvamile isetshenziselwa ukwenza amapayipi ensimbi, njengamapayipi abamba ukushisa, amapayipi amanzi okuphuza, amapayipi okufudumeza, namapayipi ahambisa igesi;Ingasetshenziswa nakwezokwakha, embonini ekhanyayo, ezezimoto, ezolimo, ezemfuyo, ezokudoba, ezentengiselwano nezinye izimboni.
Umucu wensimbi ophehliwe ukhombisa ukuthi imboni yezokwakha isetshenziselwa ikakhulukazi ukwakha amaphaneli ophahleni lwezakhiwo ezilwa nokugqwala, amagridi ophahleni, njll;Imboni yokukhanya iyisebenzisela ukwenza amagobolondo ezinto zikagesi zasendlini, oshimula bomphakathi, izitsha zasekhishini, njll., futhi imboni yezimoto iyisebenzisela kakhulu ukwakha izingxenye zezimoto ezimelana nokugqwala, njll;Ezolimo, ukufuywa kwezilwane kanye nezokudoba kusetshenziswa kakhulu njengendawo yokugcina ukudla kanye nokuthutha, amathuluzi okucubungula eqandisiwe enyama nemikhiqizo yasemanzini, njll;Ngokwezentengiselwano, isetshenziswa ikakhulukazi njengendawo yokugcina, ezokuthutha kanye nemishini yokupakisha;Ibha yesakhiwo sensimbi ye-sandalwood (insimbi emise okwe-C, Z);Insimbi elula, i-ceiling keel, njll.

Ukusetshenziswa Komucu Wensimbi
Insimbi eyi-galvanized strip ngokuvamile isetshenziselwa ukwenza amapayipi ensimbi, njengamapayipi abamba ukushisa, amapayipi amanzi okuphuza, amapayipi okufudumeza, namapayipi ahambisa igesi;Ingasetshenziswa nakwezokwakha, embonini ekhanyayo, ezezimoto, ezolimo, ezemfuyo, ezokudoba, ezentengiselwano nezinye izimboni.Imboni yezokwakha isetshenziselwa ikakhulukazi ukwakha amaphaneli ophahleni lwezakhiwo ezilwa nokugqwala, ama-roof grids, njll;Imboni yokukhanya iyisebenzisela ukwenza amagobolondo ezinto zikagesi zasendlini, oshimula bomphakathi, izitsha zasekhishini, njll., futhi imboni yezimoto iyisebenzisela kakhulu ukwakha izingxenye zezimoto ezimelana nokugqwala, njll;Ezolimo, ukufuywa kwezilwane kanye nezokudoba kusetshenziswa kakhulu njengendawo yokugcina ukudla kanye nokuthutha, amathuluzi okucubungula eqandisiwe enyama nemikhiqizo yasemanzini, njll;Ngokwezentengiselwano, isetshenziswa ikakhulukazi njengendawo yokugcina, ezokuthutha kanye nemishini yokupakisha;Ibha yesakhiwo sensimbi ye-sandalwood (insimbi emise okwe-C, Z);Insimbi elula, i-ceiling keel, njll.
Izici zomucu wensimbi: i-galvanized steel strip uhlobo lwempahla eluhlaza ebizwa ngokuthi (zinc) embozwa epuletini lensimbi elide nelincane eligoqekayo elibandayo noma eligoqekayo elishisayo.I-galvanizing eshisayo inezinzuzo zokugqoka okufanayo, ukunamathela okuqinile nokuphila isikhathi eside.Ukusabela okuyinkimbinkimbi ngokomzimba namakhemikhali phakathi kwepayipi elishisayo lensimbi ecwilisiwe kanye nesisombululo sokucwenga esincibilikisiwe kwenza ungqimba lwengxubevange ye-zinc-iron olungagqwali olunokwakheka okuhlangene.I-alloy layer ihlanganiswe ne-zin c ehlanzekile kanye ne-strip steel substrate.Ngakho-ke, inokumelana nokugqwala okuqinile.Amaphuzu ekhwalithi ensimbi ewuhlaka oluthathiwe azoba bushelelezi ngokubukeka, angabi namaqhuqhuva e-zinc nama-burrs, futhi abe mhlophe okuyisiliva;Ubukhulu buyalawuleka, phakathi kuka-5-107 μ Noma yikuphi ukukhetha ngaphakathi kwe-m;Ayikho i-hydrogen embrittlement kanye nengozi yokushisa, engaqinisekisa ukuthi izakhiwo zemishini yezinto ezibonakalayo zihlala zingashintshiwe;Ingathatha indawo yezinqubo ezithile ezidinga ukuvuthwa okushisayo;Ukumelana nokugqwala okuhle, ukuhlolwa kwesifutho sikasawoti okungathathi hlangothi kuze kufike emahoreni angama-240;Etc. Strip steel, eyaziwa nangokuthi i-steel strip, ingaphakathi kuka-1300mm ububanzi, futhi ubude bayo buhluke kancane ngokobukhulu bekhoyili ngayinye.I-strip steel ngokuvamile inikezwa ngamakhoyili, anezinzuzo zokunemba kobukhulu obuphezulu, ikhwalithi enhle yangaphezulu, ukucubungula kalula nokonga impahla.
Indlela yokupakisha: inqwaba, ikesi lezinkuni
Imodi yokuthekelisa: ezokuthutha ngemoto
