Ngasekupheleni kwawo-1980, iShayina yaqala ukwakha amayunithi okuhlanganisa imibala ngokulandelana.Iningi lalawa mayunithi lakhiwe ezitshalweni zensimbi nezensimbi nasezimbonini ezihlanganyelwe, futhi imishini yokucubungula imibala ngokuyisisekelo yayithengwa kwamanye amazwe.Ngo-2005, ibhodi elihlanganiswe ngemibala yasekhaya lase lifinyelele amathani ayizigidi ezingu-1.73, okuholele ekusetshenzisweni ngokweqile.I-Baosteel, i-Anshan Iron nensimbi, i-Benxi Iron nensimbi, iShougang, i-Tangshan Iron nensimbi, iJinan Iron nensimbi, i-Kunming Iron nensimbi, i-Handan Iron nensimbi, i-Wuhan Iron nensimbi, i-Panzhihua Iron nensimbi nezinye izinsimbi ezinkulu eziphethwe nguhulumeni. futhi amabhizinisi ensimbi anomthamo weyunithi ephezulu kanye nezinga lemishini.Bakhe ngokulandelana amayunithi okuhlanganisa imibala ngobuchwepheshe bangaphandle kanye namandla okukhiqiza onyaka angamathani ayi-120000 ~ 170000.
Ngesikhathi esifanayo, ukukhiqizwa kwamabhodi ahlanganiswe ngombala atshalwe amabhizinisi amaningi azimele ngokuvamile amukela imishini yasekhaya, enamandla amancane okukhiqiza, kodwa kuyashesha ukuqalisa kanye nokutshalwa kwezimali okuphansi.Imikhiqizo ikakhulu eyezinto zokwakha kanye nezimboni zokuhlobisa.Ngaphezu kwalokho, inhloko-dolobha yangaphandle kanye nenhloko-dolobha yaseTaiwan nayo yahlala ukuze kwakhiwe amayunithi ombala, kodwa iningi lawo ligxile ezindaweni ezisogwini.Kusukela ngo-1999, ngokuchuma kwemakethe yamapuleti ahlanganiswe ngombala, ukukhiqizwa nokusetshenziswa kwepuleti elihlanganiswe ngombala kungene enkathini yokukhula ngokushesha.Kusukela ngo-2000 kuya ku-2004, ukukhiqizwa kukhuphuke ngesilinganiso esingama-39.0%.Ngo-2005, amandla kazwelonke okukhiqiza amapuleti ahlanganiswe ngombala ayengaphezu kwamathani ayizigidi ezingu-8 / ngonyaka, futhi inani lamayunithi ahlanganiswe ngombala ayesakhiwa, anenani eliphelele lokukhiqiza likazwelonke lamathani angaphezu kwezigidi ezingu-9 / ngonyaka.
Izinkinga ezikhona: 1 Nakuba umthamo wokukhiqiza wepuleti lesisekelo se-hot-dip galvanized wezinto zokwakha mkhulu, kukhona ukushoda kwamapuleti ayisisekelo afana nekhoyili yensimbi eyisicaba eshisayo engenambali ye-zinc kanye ne-zinc alloy coil yensimbi enamale;2. Izinhlobonhlobo kanye nekhwalithi yezingubo zasekhaya azikwazi ukuhlangabezana ngokugcwele nesidingo.Intengo ephezulu yezingubo ezifakwe kwamanye amazwe inciphisa ukuncintisana.Ifilimu yepulasitiki edingekayo epuleti lombala wefilimu isadinga ukungeniswa kwamanye amazwe, futhi kunokuntuleka kwepuleti lombala wezinga eliphezulu elinoqweqwe oluwugqinsi, ukusebenza, amandla aphezulu nemibala ecebile;3. Imikhiqizo ayifani, okuholela ekumoshweni okukhulu kwezinsiza.Kunamayunithi amaningi angenawo amandla amancane anamandla angaphansi kwamathani angu-40000 ngonyaka, futhi kunezinkinga ngekhwalithi yomkhiqizo nokuvikelwa kwemithombo yemvelo;4. Kunamayunithi amaningi anemibala emisha emisha e-China, edlula kude isidingo semakethe, okuholela esilinganisweni esiphansi sokusebenza samayunithi amaningi okumboza imibala ngisho nokuvalwa.
Ithrendi yokuthuthukisa:
Okokuqala, ukusetshenziswa kwe-substrate yekhwalithi ephezulu kudinga izidingo eziphakeme neziphakeme zendawo, ukwakheka kanye nokunemba kobukhulu be-substrate.Okokusetshenziswa ngaphandle, njengembali encane ye-zinc flower flat hot-dip galvanized steel coil kanye ne-non-zinc flower flat hot-dip galvanized steel galvanized, i-zinc alloy hot-dip galvanized coil ekhuphuka ngesikhathi;Okokusetshenziswa endlini, okufana nekhoyili yensimbi, ishidi eligoqelwe ngokubanda eliboshwe kanye nekhoyili ye-aluminium.
Okwesibili, thuthukisa inqubo yokwelashwa kwangaphambili kanye noketshezi lokwelapha.Ngamathuluzi amancane kanye nezindleko eziphansi, isiphenduke inqubo evamile, futhi ithuthukisa njalo ukuzinza, ukumelana nokugqwala nokusebenza kokuvikelwa kwemvelo koketshezi lokwelashwa kwangaphambili.
Okwesithathu, ukuthuthukiswa kwezingubo ezintsha ukuthuthukisa i-polyester evamile, i-polyvinylidene fluoride (PVDF) ne-plastic sol ukuze kutholakale ukukhiqiza kabusha kombala omkhulu, ukumelana ne-UV, ukumelana ne-sulfur dioxide kanye nokumelana nokugqwala;Thuthukisa ukunamathela okusebenzayo okufana nokumelana nokungcola nokumunca ukushisa.
Okwesine, imishini yeyunithi iphelele kakhulu.Isibonelo, kusetshenziswa imishini emisha yokushisela, imishini emisha yokuhlanganisa ama-roll, izithando zomlilo ezithuthukisiwe, nezinsimbi ezizenzakalelayo ezithuthukisiwe.
Okwesihlanu, ubuchwepheshe bokukhiqiza obubandayo buphenduke inkambiso yentuthuko ngenxa yezindleko eziphansi, ukubukeka okuhle, umuzwa we-dimensional ezintathu namandla aphezulu.
Okwesithupha, qaphela ukwehlukahlukana, ukusebenza kahle kanye nezinga eliphezulu lemikhiqizo, njengebhodi yokuhlanganisa umbala womdwebo ojulile, ibhodi lokuhlanganisa “isikhumba sikagrapefruit”, ibhodi elinombala elimelene ne-static, ibhodi elinombala elimelana nokungcola, umbala wokumunca ukushisa okuphezulu. ibhodi lokugqoka, njll.
Ukuthambekela kwamanje e-China ukuthi abakhiqizi bamapuleti ahlanganiswe ngombala banaka kakhulu izinga lama-substrates asetshenziswa ekukhiqizeni kwabo amapuleti ahlanganiswe ngombala, futhi banezidingo eziphakeme neziphakeme zenqubo yabo yokukhiqiza, okwenza amapuleti ahlanganiswe ngombala abe nawo. umnikelo omuhle kakhulu ohlelweni lokukhiqiza.Ngaphezu kwalokho, imishini yokukhiqiza amapuleti ahlanganiswe ngombala nayo isithuthuke kakhulu, okwenza amapuleti ahlanganiswe ngombala abe ngaphezulu futhi azenzekela ngokugcwele ekukhiqizeni, okungagcini nje ngokusindisa izindleko, kodwa futhi kusindisa inqwaba yabasebenzi, Ngaphezu kwalokho, kukhona okuningi futhi abakhiqizi abaningi bamapuleti ahlanganiswe ngombala, futhi ukuncintisana kwemakethe kuya ngokuya kuba nolaka.Ukuthuthukisa ikhwalithi yomkhiqizo kanye nokunciphisa izindleko zokukhiqiza umkhiqizo ngokuyisisekelo sekuphenduke umkhuba ovamile wabakhiqizi bamapuleti anemibala.Imikhiqizo yebhodi enamabala anemibala isiye yahlukahluka kakhulu.Amabhodi anemibala ehlukene angadlala imisebenzi eminingi ehlukene, okwenza imakethe yebhodi enamabalazwe ibe mnandi kakhulu.
