IKHOYILI YENSIMBI EPENWE NGOKUQALA

Iyini ikhoyili yensimbi enombala ependwe kusengaphambili?

Incazelo Yomkhiqizo

I-coil yensimbi ependwe kusengaphambili iwumkhiqizo owenziwe ngensimbi eshisayo egayiwe, insimbi eshisayo egayiwe, insimbi egayiwe kagesi, njll., embozwe ngeleveli eyodwa noma eziningana zengubo yemvelo ebusweni ngemva kokwelashwa kwangaphambili kobuso (ukususwa kwamakhemikhali nokwelashwa kokuguqulwa kwamakhemikhali), ngemva kwalokho okuphulukiswa ngosizo lokubhaka. Iqanjwe ngegama le-ikhoyili yensimbi embozwe ngombalangemibala ehlukahlukene yezembozo eziphilayo, futhi ibizwa ngokuthi ikhoyili yensimbi ependwe ngaphambilini.

Izici Zomkhiqizo

Amakhoyili apendwe kusengaphambili alula futhi amahle, anokumelana okuhle nokugqwala, futhi angacutshungulwa ngqo. Ahlinzeka ngohlobo olusha lwezinto zokusetshenziswa embonini yokwakha, embonini yokwakha imikhumbi, embonini yokukhiqiza izimoto, embonini yezinto zikagesi, embonini yezinto zikagesi, njll.

Umlando Wokuthuthukiswa Kwensimbi Yekhoyili Ependiwe Ngaphambili

Inqubo Yokukhiqiza Yekhoyili Yensimbi Ependwe Ngaphambili

Kunezinqubo eziningi zokukhiqiza ezipendwe kusengaphambiliamakhoyili ensimbi ambozwe ngombalaInqubo evame ukusetshenziswa kakhulu inqubo yendabuko yokumboza nge-roller + yokubhaka. Njengoba iningi lokumboza lokwakha limbozwa kabili, inqubo yendabuko yokumboza kabili kanye nenqubo yokubhaka kabili yiyona inqubo ejwayelekile kakhulu yokukhiqiza ukumboza kombala. Izinqubo eziyinhloko zeyunithi yokumboza umbala zifaka phakathi ukwelashwa kwangaphambili, ukumboza, kanye nokubhaka.

1) Ukulungiswa kwekhoyili yensimbi

Khetha insimbi efanelekile njengesisekelo. Ezivame ukusetshenziswa yinsimbi ehlanganisiwe, insimbi ye-galvalume, insimbi ye-alloy ye-zn-al-mg, amakhoyili ensimbi aqoqwe ngokubandayo, njll. Ngemuva kwalokho amakhoyili ensimbi aphathwa ubuso, okuhlanganisa ukususa amafutha, ukususa ukugqwala kanye nezinye izinqubo ukuqinisekisa ukunamathela kwengubo.

4) Ukwelashwa kwesendlalelo sokuvikela

Ukuze kwandiswe ukumelana nesimo sezulu kanye nokumelana nokugqwala kwekhoyili embozwe ngombala, ungqimba oluvikelayo luvame ukufakwa embozweni wombala. Ungqimba oluvikelayo lungaba ungqimba olubonakalayo lwezinto eziphilayo noma ungqimba olunemisebenzi ekhethekile, njengongqimba olulwa ne-ultraviolet, ungqimba oluzihlanzayo, njll.

2) Ukwelashwa kwe-primer

Kufakwa ungqimba lwe-primer ebusweni be-coil yensimbi, esetshenziswa kakhulu ukuthuthukisa ukunamathelana phakathi kwengubo kanye ne-substrate futhi inikeze ukumelana okuthile kokugqwala. I-primer ivame ukwenziwa nge-epoxy resin, i-polyester resin nezinye izinto.

5) Ukomisa nokulungisa

Ngemva kokuqedwa kokumbozwa, ikhoyili yensimbi idinga ukuthunyelwa esithandweni sokomisa ukuze yome ukuze kususwe isinyibilikisi kanye nomswakama okumboziwe. Ngemuva kwalokho ikhoyili yensimbi ithunyelwa esithandweni sokulungisa ukuze yome ukuze imbozwe ngokuphelele nesisekelo.

3) Ukwelashwa kombala wokumboza

Kufakwa upende wombala ku-primer. Upende wombala uyisici esiyinhloko sekhoyili embozwe ngombala. Imibala ehlukene nemiphumela ingakhethwa ngokwezidingo zamakhasimende. Izinto zopende wombala ezisetshenziswa kakhulu zifaka phakathi i-polyester, i-silicon-modified polyester, i-polyvinyl fluoride, njll.

6) Ukusika nokupakisha

Ikhoyili embozwe ngombala opholile ingasikwa ngokwezidingo zamakhasimende ukuze kutholakale usayizi odingekayo. Bese kusikwaikhoyili embozwe ngombalaipakishwe ukuze ivikele isembozo ekulimaleni.

Isakhiwo Sensimbi Ependwe Kabusha

1) Ukumboza okuphezulu: ivikela ukukhanya kwelanga futhi ivimbele imisebe ye-ultraviolet ekulimazeni ingubo; lapho ingubo ephezulu ifinyelela ubukhulu obubekiwe, ingakha ifilimu yokumboza ebanzi, inciphise ukungena kwamanzi kanye nokungenela komoya-mpilo
Ukwembozwa kwe-primer: kusiza ukuqinisa ukunamathela kwi-substrate, okwenza kube lula ukuthi upende ukhiphe ukugqwala ngemva kokuba ifilimu yopende igcwele amanzi, futhi kuthuthukisa ukumelana nokugqwala, ngoba i-primer iqukethe imibala evimbela ukugqwala, njengemibala ye-chromate, evimbela i-anode futhi ithuthukise ukumelana nokugqwala
2) Isendlalelo sokuguqulwa kwamakhemikhali: kuthuthukisa ukunamathelana phakathi kwepuleti (i-galvanized, i-galvalume, i-zn-al-mg, njll.) kanye nopende (upende)
3) Ukugqoka okunensimbi: ngokuvamile i-zinc coating, i-aluzinc coating kanye ne-zinc aluminium magnesium coating, enomthelela omkhulu empilweni yokusebenza komkhiqizo. Uma i-metallic coating ijiyile, kulapho ukumelana nokugqwala kuba phezulu khona.
4) Insimbi eyisisekelo: kusetshenziswa ipuleti eligoqiwe elibandayo, futhi izakhiwo ezahlukene zinquma ukusebenza kwepuleti lombala, njengokuqina
5) Ukumboza okungezansi: kuvimbela ipuleti lensimbi ukuthi lingagqwali lisuka ngaphakathi, ngokuvamile isakhiwo esinezingqimba ezimbili (2/1M noma 2/2 primer coating + bottom coating), uma isetshenziswa njengepuleti elihlanganisiwe, kunconywa ukusebenzisa isakhiwo esinezingqimba eyodwa (2/1)
