1. Cov txheej txheem ntau lawm ntawm cov xim hlau phaj
Xim hlau phaj (tseem hu ua xim phaj, xim coated steel phaj,ppgl ua) yog ua raws li cov hlau phaj txias, galvanized steel phaj lossis galvalume steel coil, tom qab kev kho degreasing (degreasing, tu, tshuaj hloov pauv tshuaj), thiab txheej txheej (txheej txheej txheej txheej), cov khoom ua los ntawm kev ci thiab txias.
Cov txheej txheem txheej muaj xws li ob lub tsho loj thiab ib qho ci, ob lub tsho loj thiab ob lub ci, thiab lwm yam. Lub neej tsis muaj kev pabcuam yuav ua tau 10-30 xyoo nyob ntawm qhov chaw nyob.
Cov txheej txheem tseem ceeb ntawm cov txheej txheem ob-txheej thiab ob-ci hom txuas ntxiv xim txheej yog: uncoiler ------- tshuab stitching------ nias cov menyuam------tensioning tshuab--- -Uncoiling Looper----- Alkaline Degreasing ---- Ntxuav ---- Qhuav ---- Passivation ----- Qhuav ------- Pib Txheej ------- pib txheej thiab drying --- topcoat fine coating ------ topcoat drying ------ cua txias thiab txias ------ winding ua hauj lwm Teeb ------ rewinder----- (the Tom ntej no yob yog ntim thiab muab tso rau hauv cia).
Common substrates rau xim coated steel kauj (ppgi ppgl kauj)
(1) Cold dov substrate
Cov xim phaj uas ua los ntawm cov khaub thuas dov substrate muaj ib tug du thiab zoo nkauj tsos thiab muaj processability ntawm txias dov phaj;Txawm li cas los xij, txhua qhov khawb me me hauv cov txheej txheej saum npoo yuav nthuav tawm cov khaub thuas-kuav los tiag substrate rau saum huab cua, uas yuav nthuav tawm cov hlau sai sai rau qhov tsim cov xeb liab.Yog li ntawd, cov khoom zoo li no tsuas yog siv tau rau kev ntsuas kev cais tawm ib ntus thiab cov khoom siv sab hauv uas tsis tshua muaj.
(2) Kub dip galvanized substrate
Cov khoom tau txais los ntawm txheej txheej organic rau ntawmkub-dip galvanized kaujyog kub-dip galvanized xim-coated ntawv.Ntxiv rau qhov kev tiv thaiv ntawm zinc, cov organic txheej rau ntawm qhov chaw ntawm cov ntawv kub-dip galvanized xim-coated kuj plays lub luag hauj lwm ntawm rwb thaiv tsev thiab kev tiv thaiv, tiv thaiv xeb, thiab kev pab cuam lub neej yog ntev tshaj li ntawm kub-dip. galvanized ntawv.Cov ntsiab lus zinc ntawm kub-dip galvanized substrate feem ntau yog 180g / m2 (ob tog), thiab qhov siab tshaj plaws zinc ntsiab lus ntawm kub-dip galvanized substrate rau lub tsev sab nrauv yog 275g / m2.
(3) Kub-dip Al-Zn substrate
Ntawm kev thov, hot-dip galvalume kaujKuj tseem siv tau los ua xim-coated substrates (55% AI-Zn thiab 5% AI-Zn).
(4) Electro-galvanized substrate
Cov ntawv electro-galvanized yog siv los ua cov substrate, thiab cov khoom tau los ntawm txheej cov xim organic thiab ci yog electro-galvanized xim-coated ntawv.Vim tias cov zinc txheej ntawm cov ntawv electro-galvanized yog nyias, cov ntsiab lus zinc feem ntau yog 20/20g / m2, yog li cov khoom no tsis haum rau kev siv.Ua phab ntsa, ru tsev, thiab lwm yam sab nraum zoov.Tab sis vim nws cov tsos zoo nkauj thiab kev ua haujlwm zoo heev, nws tuaj yeem siv rau hauv cov khoom siv hauv tsev, suab, steel rooj tog, kho kom zoo nkauj sab hauv, thiab lwm yam.
Sab saum toj nto coated ob txheej xim thiab ib txheej ntawm cov xim-coated rau sab nraum qab (cov xim no feem ntau tsis haum rau pem hauv ntej siv)
Prepainted steel coil (ppgi ppgl) yog cov khoom ua los ntawm cov ntawv txias-kuav los tiag, kub-dip galvanized steel ntawv los yog galvalume steel nplooj ntawv tom qab degreasing nto, phosphating thiab chromate kho, thiab ces coated nrog organic xim thiab ci.Feem ntau siv cov xim coated steel daim hlau yog polyester (BHP XRW txheej system, Baosteel JZ, Kauslim PGS, Taiwan PE), ua raws li silicone resin (PSS), fluorine resin (PVDF), thiab lwm yam. Cov txheej txheem txheej yog muab faib ua ob. Cov txheej tuab yog feem ntau 20-25μ ntawm qhov chaw thiab 8-10μ nyob rau sab nraub qaum.Cov txheej txheem feem ntau hais txog xim-coated steel ntawv yog American ASTM A527 (galvanized), ASTM AT92 (txhuas-zinc), Japanese JIS G3302, European EN/0142, Kauslim KS D3506, Baosteel Q / BQB420
