1. Inkqubo yokuvelisa ipleyiti yensimbi yombala
Ipleyiti yentsimbi yombala (ekwabizwa ngokuba yipleyiti yombala, ipleyiti yentsimbi enombala,ippgi ppgl) isekelwe kwintsimbi epholileyo epholileyo, i-galvanized steel plate okanye i-galvalume steel coil, emva kokulungiswa kwendawo (i-degreasing, ukucoca, unyango lokuguqulwa kweekhemikhali), kunye nokugubungela (indlela yokugqoka i-roller), imveliso eyenziwe ngokubhaka kunye nokupholisa.
Isakhiwo sokugquma sibandakanya iingubo ezimbini kunye nokubhaka enye, iingubo ezimbini kunye neebhaka ezimbini, njl njl. Ubomi benkonzo yokugcinwa kwamahhala bunokuba yiminyaka eyi-10-30 ngokuxhomekeke kwimoya ekhoyo.
Eyona nkqubo yemveliso yodidi oluqhelekileyo lokutyabeka kabini kunye nohlobo lokubhaka oluqhubekayo lweyunithi yokwambathisa yombala yile: i-uncoiler -------------stitching machine------cofa roller--------tensioning machine--- -Uncoiling Looper-----Ukucoca ialkaline----Drying-----Passivation-----Drying------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ - ukomisa------ topcoat icoat entle------ ukomiswa kwedyasi yengaphezulu------ ukupholisa umoya kunye nokupholisa------- umsebenzi wokujija umsebenzi Seti ----- ukubuyisela----- (i umqulu olandelayo upakishwe kwaye ubekwe kwindawo yokugcina).
Iisubstrates eziqhelekileyo zecoil yentsimbi eqatywe ngombala (ppgi ppgl coil)
(1) I-substrate eqengqelekayo ebandayo
Ipleyiti yombala eveliswe kwi-substrate epholileyo inembonakalo egudileyo kwaye intle kwaye inokuqhubekeka kwepleyiti epholileyo;kunjalo, nakuphi na imikrwelo emincinci kwindawo yokwaleka kuya kubhenca i-substrate epholileyo emoyeni, eya kuthi iveze ngokukhawuleza intsimbi kwi-Ivelisa irusi ebomvu.Ngoko ke, iimveliso ezinjalo zingasetyenziselwa kuphela amanyathelo okuzihlukanisa okwethutyana kunye nezixhobo zangaphakathi ezineemfuno eziphantsi.
(2) Idiphu eshushu i-galvanized substrate
Imveliso efunyenwe ngokugquma i-organic coating kwieshushu-diphu ikhoyili yagalvanizedlishiti elishushu-diphu elenziwe ngesinyithi ngombala.Ukongeza kwimpembelelo ekhuselayo ye-zinc, i-organic coating phezu kwe-hot-dip galvanized color-coated sheet nayo idlala indima yokukhusela kunye nokukhusela, ukukhusela i-rust, kwaye ubomi benkonzo bude kunoko-dip eshushu. ishidi elenziwe ngesinyithi.Umxholo we-zinc we-hot-dip galvanized substrate ngokubanzi yi-180g/m2 (i-double-side), kwaye umxholo we-zinc ophezulu we-hot-dip galvanized substrate yokwakhiwa kwangaphandle yi-275g / m2.
(3) I-Hot-dip Al-Zn substrate
Ngesicelo, hot-dip ikhoyili galvalumeinokusetyenziswa kwakhona njengama-substrates afakwe umbala (55% AI-Zn kunye ne-5% AI-Zn).
(4) I-electro-galvanized substrate
I-electro-galvanized sheet isetyenziswa njenge-substrate, kwaye imveliso efunyenwe ngokugquma ipeyinti yezinto eziphilayo kunye nokubhaka i-electro-galvanized color-coated sheet.Ngenxa yokuba i-zinc layer ye-electro-galvanized sheet incinci, umxholo we-zinc udla ngokuba ngu-20/20g/m2, ngoko ke le mveliso ayifanelekanga ukusetyenziswa.Yenza iindonga, uphahla, njl. ngaphandle.Kodwa ngenxa yenkangeleko yayo entle kunye nokusebenza okugqwesileyo, inokusetyenziswa ikakhulu kwizixhobo zasekhaya, iaudio, ifenitshala yentsimbi, umhombiso wangaphakathi, njl.
Umphezulu wepeyinti uqatywe iileya ezimbini zepeyinti kunye nomaleko wombala ogqunywe ngasemva (olu hlobo lwepeyinti yangasemva alufanelekanga ukusetyenziswa ngaphambili)
I-coil yensimbi efakwe ngaphambili (i-ppgi ppgl) yimveliso eyenziwe ngeshiti lentsimbi epholileyo, i-hot-dip galvanized sheet okanye i-galvalume sheet sheet emva kokuchithwa komphezulu, i-phosphating kunye ne-chromate unyango, kwaye emva koko ifakwe ngepeyinti yezinto eziphilayo kwaye zibhakiwe.Iipleyiti eziqhelekileyo ezisetyenziswayo kwiipleyiti zentsimbi ezinombala ziyi-polyester (i-BHP XRW inkqubo yokugqoka, i-Baosteel JZ, i-Korea PGS, i-Taiwan PE), ilandelwa yi-silicone resin (PSS), i-fluorine resin (PVDF), njl. Ubungqingqwa bengubo ngokuqhelekileyo yi-20-25μ kumphezulu kunye ne-8-10μ ngasemva.Imigangatho ekhankanyiweyo ngokuqhelekileyo kumaphepha entsimbi agqunywe ngombala yiAmerican ASTM A527 (galvanized), ASTM AT92 (aluminium-zinc), Japanese JIS G3302, European EN/0142, Korea KS D3506, Baosteel Q/BQB420
