Esikhathini esivela njalo somkhakha wensimbi, isidingo sezinto ezisezingeni eliphakeme, izinto eziqinile ziqhubeka zikhuphuka. Phakathi kwemikhiqizo efunwe kakhulu ngemuva kwamakhoyili yensimbi enezinsimbi, ezibalulekile ezinhlobonhlobo zezicelo, ekwakhiweni ekukhiqizweni kwezithuthi. Ngaphambili kwalesinambiswano yi-Jindalai Steel Company, umholi ekukhiqizweni kwemigqa yensimbi ye-Alu-zinc, kufaka phakathi i-PPGI (Pre-Paint Galvanized Iron) ne-PPGL (Pre-Paint Gallvalume).
Ukuqonda ukukhiqizwa kwensimbi ye-Alu-zinc
I-Alu-zinc Steel, eyaziwa nangokuthi i-galvalume, uhlobo lwensimbi ehlanganisiwe ehlanganisa izinzuzo ze-aluminium ne-zinc. Le nhlanganisela eyingqayizivele ihlinzeka ngokumelana nokuqina okuphezulu, okwenza kube yisinqumo esihle sezicelo zangaphandle nezindawo ezithambekele kumswakama. Ulayini wokukhiqizwa kwensimbi ye-Alu-zinc eJindaland Steel yakhelwe ukukhiqiza amakhoyili wensimbi esezingeni eliphakeme ahlangabezana nezidingo eziqinile zezimboni ezahlukahlukene.
Inqubo yokukhiqiza ifaka ukusetshenziswa kwenhlanganisela okuvame ukuhlanganisa i-aluminium engu-55%, 43.4% zinc, kanye ne-1.6% silicon. Le nhlanganisela ayikhuli nje kuphela ukuqina kwensimbi kodwa futhi ithuthukisa isikhalazo sayo sobuhle, okwenza kube ukukhetha okuthandwayo kwezicelo zokwakha. Umugqa wokukhiqizwa kwensimbi ye-Alu-Zinc uhlome ngobuchwepheshe obuthuthukisiwe obuqinisekisa ikhwalithi nokusebenza okuhle, okuvumela inkampani yensimbi yeJingani ukuze ihlangabezane nesidingo esikhulayo semikhiqizo yensimbi ye-Galvanized.
Ukuguquguquka kwama-coils wensimbi egayiwe
Amakhoyili ensimbi enziwe nge-gary Le nqubo inwebeka kakhulu isikhathi sokuphila kwensimbi, okwenza kube yisixazululo esisebenza ngempumelelo kwezicelo ezahlukahlukene. I-Jindalai Steel Company inikeza uhla olubanzi lwemikhiqizo yensimbi ye-Galvanized Steel, kufaka phakathi i-PPGI ne-PPGL, etholakala ngobukhulu obuhlukahlukene, ububanzi, kanye nezimbobo.
Ukucaciswa komkhiqizo
- "Ubukhulu": 0.1-2.0 mm
- "Ububanzi": 600mm-1500mm
- "I-coating":
- I-PPGI: Z20-Z275
- I-PPLL: AZ30-AZ185
- "Izinhlobo ze-coating": I-PE
- "Ubukhulu be-coating": 5 + 20mic / 5mic
- "Izinketho zombala": umbala we-ral noma owenziwe ngokwezifiso ngokusho kwamasampula amakhasimende
Lokhu kucaciswa kuqokomisa ukuguquguquka kwemikhiqizo yensimbi ye-jindaai yensimbi ye-jindalai, kubenza balungele izinhlobo eziningi zezicelo, kufaka phakathi ukufakwa kophahla, nezindawo ezidongeni nezimoto.
Izinzuzo ze-PPGI ne-PPGL
I-PPGI ne-PPGL ithandwa kakhulu emikhakheni yokwakha kanye nokwakha ngenxa yesikhalazo sabo sobuhle nokuqina. Ukuqedwa kwangaphambi kopende kuvumela imibala nemiklamo ehlukahlukene, ukunika amandla abaklami nabaklami ukudala izinhlaka ezibonakalayo ngaphandle kokuyekethisa ngekhwalithi. Ngokwengeziwe, izimbobo ezivikelayo ezisetshenziswa emikhiqizweni ye-PPGI ne-PPLL zithuthukisa ukumelana nazo ekuvinjezelweni kwezulu, imisebe ye-UV, nokuvezwa kwamakhemikhali.
Ukusetshenziswa kwensimbi ye-galvanized, ikakhulukazi ngesimo se-PPGI ne-PPGL, nakho kuyindlela enobungani bemvelo. Inqubo yokukhiqiza ikhiqiza imfucumfucu encane uma iqhathaniswa nokukhiqizwa kwensimbi yendabuko, kanye nokuphila isikhathi eside kwale mikhiqizo kunciphisa isidingo sokufakwa kabusha kwezidingo, kunciphisa futhi umthelela wezemvelo.
Izitayela zezimboni kanye nezinto ezintsha
Njengoba imboni yensimbi iyaqhubeka nokuvela, izitayela eziningana zibumba ikusasa lokukhiqizwa kwensimbi egayiwe. Umkhuba owodwa obalulekile yisidingo esandayo sezinto ezizinzile nezinobungane. Inkampani ye-Jindalai yensimbi inezinto ezizibophezele ekufuneni lesi sidingo ngokusebenzisa imikhuba ebhekene nemvelo kuyo yonke izinqubo zayo zokukhiqiza.
Omunye umkhuba ukuthandwa okukhulayo kwezinto ezingasindi ekwakheni nasekukhiqizweni. I-Alu-zinc Steel, ngesilinganiso sayo esihle kakhulu sokuqina kwesisindo, iba yinketho ekhethwayo yezicelo eziningi. I-Jindalai Steel Company isengaphambili kwalokhu okusha, ukuthuthukisa ngokuqhubekayo umugqa wokukhiqiza wensimbi ye-Alu-Zinc ukuletha imikhiqizo yensimbi esezingeni eliphakeme, engasindi.
Ukugcina
Ekuphetheni, ikusasa lemboni yensimbi likhanya, ngezinto ezintsha ekukhiqizweni kwensimbi ye-Alu-zinc kanye nezixazululo zensimbi egciniwe ehola indlela. Inkampani ye-Jindalai yensimbi ivelele njengomholi kulo mkhakha, enikeza imikhiqizo ehlukahlukene, kufaka phakathi i-PPGI ne-PPGL, ehlangabezana namazinga aphezulu kakhulu wekhwalithi nokuqina. Njengoba ukufunwa kwensimbi ye-galvanized kuqhubeka ukukhula, inkampani yensimbi yeJindalai ibekelwe kahle ukuhlinzeka imboni ngezixazululo ezintsha ezidinga ukuchuma.
Noma ngabe uyakhiwa, ekwakheni, noma yimuphi omunye umkhakha odinga imikhiqizo esezingeni eliphakeme yensimbi, inkampani yensimbi ye-jingalai ingumlingani wakho othembekile kuzo zonke izidingo zakho zensimbi enziwe ngensimbi. Ngokuzibophezela kokwenza okuhle nokusimama, sizinikezele ekubumbeni ikusasa lomkhakha wensimbi, ikhoyili eyodwa yensimbi egcwele ngasikhathi.
