1. Le gaosiga o le gaosiga o lanu uʻamea ipu
Pepa u'amea lanu (fa'aigoa o ipu lanu, ipu u'amea lanu lanu,ppgi ppgl) o loʻo faʻavae i luga o le uʻamea uʻamea malulu, ipu uamea uʻamea poʻo le uamea galvalume coil, pe a maeʻa le faʻaogaina o le eleele (dereasing, faʻamamaina, vailaʻau faʻaliliu togafitiga), ma le faʻapipiʻiina (auala faʻapipiʻi taʻavale), o se oloa e faia i le taoina ma le malulu.
O le fausaga faʻapipiʻi e aofia ai ni peleue se lua ma le tasi tao, lua peleue ma lua tao, ma isi. O le ola tautua e leai se tausiga e mafai ona 10-30 tausaga e faʻatatau i le siosiomaga faʻafefe.
O le faagasologa o le gaosiga autu o le masani e lua-faʻapipiʻi ma lua- tao ituaiga faʻaauau pea lanu lanu iunite o le: uncoiler -------su'i masini------oomi uila ------tensioning machine ----- -Tatala Looper----- Alkaline Degreasing----Fa'amama----Faamago-----Passivation-----Faamago------Amata Ufiufi ------- uluai ufiufi ma fa'amago------ fa'ato'a fa'amalo lelei------ fa'agogo------ fa'alili ma fa'alili------ galuega fa'a'alili Seti ----- toe fa'afo'i----- (le o lo'o soso'o lo'o fa'apipi'i ma tu'u i le fa'aputuga).
Mea masani mo le vili uamea ua ufiufi lanu (ppgi ppgl coil)
(1) Su'ega taai malulu
O le lanu lanu e maua mai i le malulu-rolled substrate o loʻo i ai se foliga lamolemole ma matagofie ma o loʻo i ai le faʻagasologa o le faʻafefeteina malulu;ae ui i lea, soʻo se mataʻitusi laiti i luga o le ufiufi o le a faʻaalia ai le malulu-taai substrate i le ea, lea o le a vave faʻaalia le uʻamea i le Ea mumu mumu.O le mea lea, o ia oloa e mafai ona faʻaaogaina mo naʻo le tuʻuesea le tumau ma mea i totonu e maualalo manaʻoga.
(2) Su'ega uamea fa'a'u'u vevela
O le oloa e maua e ala i le faʻapipiʻiina o le faʻapipiʻiina o meaola i luga o leu'amea fa'amea fa'a'u'uo le ie vevela fa'a'u'umea fa'apipi'i lanu.I le faʻaopoopoga i le puipuiga o le zinc, o le faʻapipiʻiina o meaola i luga o le pito i luga o le vevela-dip galvanized color-coated sheet o loʻo taʻalo foi le sao o le faʻamalama ma le puipuiga, puipuia ai le ele, ma o le ola tautua e umi atu nai lo le vevela-dip. laupepa uamea.Ole mea ole zinc ole mea fa'apipi'i vevela e masani ona 180g/m2 (fa'alua itu), ma o le maualuga ole zinc o lo'o i totonu ole mea fa'apipi'i vevela mo le fale i fafo e 275g/m2.
(3) Su'ega Al-Zn vevela
I luga o le talosaga, hot-dip galvalume coile mafai foʻi ona faʻaaogaina e fai ma mea faʻapipiʻi lanu (55% AI-Zn ma 5% AI-Zn).
(4) Electro-galvanized substrate
O le laupepa eletise eletise e faʻaaogaina e fai ma sui, ma o le oloa e maua e ala i le faʻapipiʻiina o le vali faʻalaʻau ma le taoina o le laupepa faʻapipiʻiina lanu eletise.Talu ai ona o le zinc layer o le electro-galvanized sheet e manifinifi, o le zinc content e masani lava 20 / 20g / m2, o lea e le talafeagai ai lenei oloa mo le faʻaaogaina.Fai puipui, taualuga, ma isi mea i fafo.Ae ona o lona foliga matagofie ma le lelei o le gaosiga o gaioiga, e mafai ona faʻaaogaina i masini fale, leo, meaafale uʻamea, teuteuga totonu, ma isi.
O le pito i luga o loʻo faʻapipiʻiina ni faʻailoga se lua o le vali ma se faʻailoga lanu i le pito i tua (o lenei ituaiga o vali tua e masani lava e le talafeagai mo le faʻaoga i luma)
Prepainted coil uamea (ppgi ppgl) o se oloa e faia i le malulu-loai ie uʻamea, vevela-dip uʻamea uʻamea laupepa po o galvalume pepa uamea ina ua uma degreasing luga, phosphating ma chromate togafitiga, ona ufiufi lea i le vali ogalaau ma tao.O le faʻaaogaina masani mo paʻu uʻamea lanu lanu o le polyester (BHP XRW coating system, Baosteel JZ, Korea PGS, Taiwan PE), sosoo ai ma le silicone resin (PSS), fluorine resin (PVDF), ma isi. Ua vaevaeina le fausaga faʻapipiʻi i lua O le mafiafia o le ufiufi e masani lava 20-25μ i luga ma 8-10μ i tua.O tulaga masani o loʻo taʻua mo laupepa uʻamea lanu lanu o Amerika ASTM A527 (galvanized), ASTM AT92 (alumi-zinc), Iapani JIS G3302, Europa EN / 0142, Korea KS D3506, Baosteel Q / BQB420
