Ukukhethwa kwentolo engaphakathi yamakani e-tinplate (okungukuthi, amathini ensimbi anathayela) ngokuvamile kuncike esimweni sokuqukethwe, okuhloswe ukuthuthukisa ukumelana nokugqwala kwekani, ukuvikela ikhwalithi yomkhiqizo, nokuvimbela ukusabela okungathandeki phakathi kwensimbi nokuqukethwe. Ngezansi okuqukethwe okuvamile kanye nokukhetha okuhambisanayo kwezingubo zangaphakathi:
1. Iziphuzo (isb., iziphuzo ezibandayo, amajusi, njll.)
Eziphuzweni eziqukethe izithako ezine-asidi (ezifana nejusi kalamula, ijusi yewolintshi, njll.), okokunamathela ngaphakathi kuvamise ukuba yi-epoxy resin coating noma i-phenolic resin coating, njengoba lezi zembozo zinikeza ukumelana ne-asidi okuhle kakhulu, kuvimbele ukusabela phakathi kokuqukethwe nensimbi futhi kugwenywe ukunambitheka okunganambitheka noma ukungcola. Eziphuzweni ezingenayo i-acidic, i-polyester elula (njengefilimu ye-polyester) ngokuvamile yanele.
2. Ubhiya nezinye iziphuzo ezidakayo
Uphuzo oludakayo lugqwala kakhulu ezinsimbi, ngakho-ke i-epoxy resin noma i-polyester coatings ivame ukusetshenziswa. Lezi zingubo zokumboza zihlukanisa ngokuphumelelayo utshwala ethini lensimbi, ukuvimbela ukugqwala nokushintsha kwe-flavour. Ukwengeza, ezinye izimbotshana zinikeza ukuvikelwa kwe-oxidation nokuvikela ukukhanya ukuvimbela ukunambitheka kwensimbi ekungeneni esiphuzweni.
3. Imikhiqizo yokudla (isb, amasobho, imifino, inyama, njll.)
Ngemikhiqizo yokudla okunamafutha amaningi noma okune-asidi ephezulu, ukukhetha kokumboza kubaluleke kakhulu. Izembatho zangaphakathi ezivamile zihlanganisa i-epoxy resin, ikakhulukazi i-epoxy-phenolic resin composite coatings, enganikezeli nje ukumelana ne-asidi kodwa futhi ingamelana namazinga okushisa aphezulu kanye nezingcindezi, iqinisekisa ukugcinwa kwesikhathi eside kanye nokuphila kweshalofu kokudla.
4. Imikhiqizo yobisi (isb, ubisi, imikhiqizo yobisi, njll.)
Imikhiqizo yobisi idinga ukumbozwa okuphezulu, ikakhulukazi ukugwema ukusebenzisana phakathi kwe-coating kanye namaprotheni namafutha obisi. Izembatho ze-polyester zivame ukusetshenziswa njengoba zinikeza ukumelana ne-asidi okuhle kakhulu, ukumelana ne-oxidation, nokuzinza, ukulondoloza ngempumelelo ukunambitheka kwemikhiqizo yobisi nokuqinisekisa ukugcinwa kwayo isikhathi eside ngaphandle kokungcola.
5. Amafutha (isb, amafutha adliwayo, amafutha okugcoba, njll.)
Ngemikhiqizo kawoyela, ukugqoka kwangaphakathi kufanele kugxile ekuvimbeleni uwoyela ukuthi angaphenduli ngensimbi, agweme ama-flavour noma ukungcola. I-epoxy resin noma i-polyester coatings ivame ukusetshenziswa, njengoba lezi zimbozo zihlukanisa ngokuphumelelayo amafutha ngaphakathi kwensimbi yekani, iqinisekisa ukuzinza nokuphepha komkhiqizo kawoyela.
6. Amakhemikhali noma amapende
Emikhiqizweni okungekona okokudla njengamakhemikhali noma opende, ukunamathela kwangaphakathi kudinga ukunikeza ukumelana nokugqwala okuqinile, ukumelana namakhemikhali, nokumelana nezinga lokushisa eliphezulu. I-epoxy resin coatings noma i-chlorinated polyolefin coatings ivame ukukhethwa, njengoba ivimbela ngempumelelo ukusabela kwamakhemikhali futhi ivikela okuqukethwe.
Isifinyezo Semisebenzi Yokumboza Ngaphakathi:
• Ukumelana nokugqwala: Ivimbela ukusabela phakathi kokuqukethwe nensimbi, inwebe isikhathi seshelufu.
• Ukuvimbela ukungcola: Igwema ukuvuza kwezinambitheka zensimbi noma ezinye izinambitheka ezingezinhle kokuqukethwe, kuqinisekisa ikhwalithi yokunambitha.
• Izici zokuvala: Ithuthukisa ukusebenza kokuvala kwekani, iqinisekise ukuthi okuqukethwe akuthintwa izinto zangaphandle.
• Ukumelana ne-oxidation: Yehlisa ukuchayeka kokuqukethwe ku-oxygen, ibambezela izinqubo ze-oxidation.
• Ukumelana nokushisa: Kubaluleke kakhulu emikhiqizweni ecutshungulwa izinga lokushisa eliphezulu (isb., ukuvala inzalo ekudleni).
Ukukhetha i-coat engaphakathi efanele kungaqinisekisa ngempumelelo ukuphepha kanye nekhwalithi yomkhiqizo opakishiwe ngenkathi uhlangabezana namazinga okuphepha kokudla kanye nezidingo zemvelo.
