Embuthanweni wokuhweba ngokucubungula insimbi, esinye sezihloko eziye zaxoxwa kaningi muva nje udaba lokuqondanisa olujwayelekile phakathiI-Gi Gl PPGIkanye ne-China Prepainted Aluzinc Steel Coil. Abathengi abaningi, lapho bekhetha ama-coil ensimbi anombala, bavame ukuzizwa bengaqiniseki kancane uma bebona uhlu olude lwemingcele ye-Ikhoyili Yensimbi Embozwe Ngombala.
Eqinisweni, le ndlela yokuxhumana ilula kakhulu. Ake sithathe ikhoyili yensimbi ye-PPGL ethandwayo emakethe njengesibonelo. Uma usuyibonile, uzoqonda.
I-PPGL empeleni imelela "ukuthinta kokuqeda" ku-galvalume (insimbi embozwe nge-aluminium-zinc). Inqubo yayo yokukhiqiza ayiyona imfihlakalo: izinto eziyisisekelo zidlula ekususweni kwamakhemikhali kanye nokwelashwa kokuguqulwa ukuze kuhlanzwe kahle indawo, bese kufakwa izendlalelo ezilodwa noma eziningi zezingubo eziphilayo, bese ekugcineni zibhakwa ekushiseni okuphezulu ukuze kubekwe ukuma.
Yiziphi izinzuzo zokwenza lokhu?
Izisebenzi eziningi ezinolwazi ziyazi ukuthi yize ishidi le-zinc elenziwe nge-aluminium likwazi ukumelana nokugqwala, livame ukuba nezinkinga uma lishiywa liveziwe isikhathi eside. Kodwa-ke, i-PPGL organic coating ifana nesembatho sokuvikela ikhoyili yensimbi. Imboza ngokuqinile ungqimba lwe-aluminium-zinc futhi iyakhanga futhi iyakwazi ukugcina umoya nomswakama kungangeni.
Ngokusho kwempendulo yedatha evela emnyangweni wezobuchwepheshe we-ZZ Group, le ndlela yokuvikela enezingqimba ezimbili yenze ukuthi isikhathi sokuphila se-Color Coated Steel CoilX sibe side cishe ngokuphindwe ka-1.5 kunesezingqimba zensimbi ze-zinc ezivamile ezenziwe nge-aluminium. Kubakhiqizi abakhiqiza izakhiwo zangaphandle noma amagobolondo emishini, lokhu kusho ukwehla okukhulu kwezindleko zokulungisa.
Uma sikhuluma ngalokhu, kufanele sikhulume ngeQembu le-ZZ.
Mhlawumbe abanye abantu abasha abajwayelene nabo bangase bangazi ngakho. I-ZZ Group yaqala ukusebenza kwayo ekuqaleni kwawo-1980, futhi indlunkulu yayo itholakala eSifundeni saseYangpu, eShanghai. Njengoba ikwazi ukusungula indawo ebhizinisini lokuhweba ngensimbi ngaleso sikhathi futhi iqhubeka nokukhula ukuze ihlanganise ukucutshungulwa kwensimbi, izinto zokusetshenziswa, izindlu, ngisho nokutshalwa kwezimali, ngenhloko-dolobha ebhalisiwe engu-200 million yuan, lolu "uphawu oluqinile" olunamandla embonini.
Umkhiqizo oyinhloko abawukhangisayo njengamanje,Ikhoyili Yensimbi Ye-Aluzinc Ependwe Ngaphambili YaseShayina, bakwazile ukuhlangabezana nezindinganiso ngqo ngoba babeziqonda ngokugcwele izindinganiso ze-Gi Gl PPGI. Kusukela esisindweni sesendlalelo se-aluminium-zinc sezinto eziyisisekelo (40-275g/m²), kuya kungakhathaliseki ukuthi isembozo somphezulu siyi-PE noma i-PVDF, isinyathelo ngasinye sasiphathwa ngokucophelela.
Ngakho-ke, uma ufuna ikhoyili enemibala engahlangabezana nezidingo zamandla futhi imelane nokugqwala ngaphandle, ungase ufune ukubheka i-PPGL. Akuyona ubuchwepheshe obusha obushintshayo, kodwa maqondana "nokuqina", empeleni ithathe isinyathelo esibalulekile uma kuqhathaniswa nemikhiqizo emidala.
