SGCC DX51D Z275 Z350 Ikhoyili yentsimbi eDitshweyo eDitshweyo eshushu yephepha lokufulela
Intshayelelo yeMveliso
I-coil yensimbi ye-galvanized yimpahla eveliswa yinkqubo eqhubekayo ye-hot-dip galvanizing kunye ne-hot-rolled steel strip okanye i-cold-rolled strip strip njenge-substrate.Ikhoyili yediphu eshushu efakwe kwikhoyili efakwe kwimo yekhoyili emva kokujiyile.Ngoko ke, ishiti lentsimbi ekhandisiweyo (ikhoyili) linokwahlulwa libe yicoil yamaphepha enziwe ngegalvanized eshushu kunye ne-coil epholileyo eqengqelekayo eshushu-dip.Zisetyenziswa ikakhulu kwimimandla yokwakha, izixhobo zasekhaya, iimoto, izitya, ezothutho kunye neshishini lasekhaya.Ngokukodwa kulwakhiwo lwentsimbi, ukwenziwa kweemoto, ukwenziwa kwendawo yokugcina izinto yentsimbi kunye namanye amashishini.Iimpawu zabo eziphambili zezi: ukuxhathisa okuqinileyo kwe-corrosion, umgangatho omhle womphezulu, inzuzo ekusebenzeni okunzulu, uqoqosho kunye nokusebenza, njl.
Ikhoyili yentsimbi evundisiweyo yogqunywa ngokwezinki ngenxa yokuba umhlwa awusayi kuhlasela le ntsimbi ikhuselayo.Olona luhlu lwangaphandle luyi-zinc yonke, kodwa iileya ezilandelelanayo zingumxube we-zinc kunye nentsimbi, kunye nengaphakathi lentsimbi ecocekileyo.Ezi zingqimba ezininzi zinoxanduva lwepropati emangalisayo yesinyithi ukumelana neemeko ezibangela ukubola.I-Zinc iphinda ikhusele intsimbi ngokusebenza "njengomaleko wedini."Ukuba umhlwa ubambe umphezulu wekhoyili yentsimbi, i-zinc iya kuqala idleke.Oku kuvumela i-zinc esasazwa phezu kokuphulwa okanye ukukrazula ukukhusela umhlwa ekufikeleleni kwintsimbi.Kwizicelo ezingenakubalwa zangaphandle, zaselwandle, okanye kwimizi-mveliso, ikhoyili yentsimbi eyiGalvanized yinxalenye ebalulekileyo yokwenziwa.
Iimfuno zokubunjwa kweekhemikhali zekhoyili yegalvanized ziyahluka kumazwe ahlukeneyo.Umgangatho welizwe kukufumanisa umxholo wekhabhoni, i-manganese, i-phosphorus, isulfure kunye ne-silicon.

Iintlobo zeekhoyili zentsimbi
Ngokwendlela yokucubungula, sahlula isinyithi segalvanized kwezi ndidi zilandelayo:
1. I-Hot-dip yeNsimbi yeNtsimbi
Njengoko igama lisitsho, i-hot-dip galvanizing intywilisela intsimbi ecociweyo kwibhafu ye-zinc etyhidiweyo malunga ne-500 degrees ukwenza umaleko we-zinc.Yeyona ndlela isetyenziswa kakhulu.Ineempawu eziluncedo:
I-1) Yonke indawo yensimbi ihlanganiswe ngokufanayo kunye ne-zinc layer, kunye neekona, imigodi, njl. ukwenzela ukuba ishidi lensimbi likhuselwe ngokupheleleyo.
2) Iindleko zokugalela amanzi ashushu zitshiphu.
2. I-Electro-galvanized Steel Coil
I-Electro-galvanizing yinkqubo yokubeka uluhlu lwezinc kwintsimbi nge-electroplating, kunye ne-anode ye-saline kunye ne-conductor yensimbi.Iyakwazi ukunyusa i-corrosion kunye nokumelana nokushisa kwentsimbi.Kwakhona, yenza amaphepha entsimbi abukeke ngakumbi.
