1. Iyo nzira yekugadzira yemavara simbi ndiro
Ruvara simbi ndiro (inozivikanwawo seruvara ndiro, ruvara coated simbi ndiro,ppgi ppgl) inobva pandiro yesimbi inotonhora, galvanized steel plate kana galvalume steel coil, mushure mekugadzirwa kwepamusoro (degreasing, kuchenesa, kushandiswa kwemakemikari ekushandura), uye kuvhara (roller coating method), chigadzirwa chinogadzirwa nekubheka uye kutonhora.
Chimiro chekuputira chinosanganisira majasi maviri uye kubheka imwe, majasi maviri uye mabheki maviri, nezvimwewo. Hupenyu hwebasa rekuchengetedza hunogona kuva makore 10-30 zvichienderana nemamiriro ekunze.
Iyo huru yekugadzira maitiro eyakajairwa maviri-kubikira uye maviri-kubikira mhando inoenderera neruvara coating unit ndeye: uncoiler --------------------------pressing roller-------tensioning machine--- -Uncoiling Looper-----Alkaline Degreasing----Kuchenesa----Kuomesa------Passivation-----Kuomesa------Kutanga Coating ------- yekutanga coating uye kuyanika------ topcoat fine coating------ topcoat drying------ air kutonhodza nekutonhodza------ mamhepo basa Seti ----- rewinder----- (the inotevera roll yakarongedzwa uye inoiswa mudura).
Yakajairika substrates yeruvara yakavharwa simbi coil (ppgi ppgl coil)
(1) Cold rolled substrate
Iyo ndiro yemavara inogadzirwa kubva kune inotonhora-yakakungurutswa substrate ine yakatsetseka uye yakanaka chitarisiko uye ine processability yeinotonhora-yakakungurutswa ndiro;zvisinei, chero diki anokwenya ari pamusoro rukoko achafumura inotonhora-akakungurutswa substrate kumhepo, izvo achakurumidza kufumura simbi kuna Generates tsvuku ngura.Nokudaro, zvigadzirwa zvakadaro zvinogona kushandiswa chete kwechinguva chiduku matanho uye zvinhu zvemukati zvine zvishoma zvinodiwa.
(2) Kupisa dip galvanized substrate
Chigadzirwa chinowanikwa nekuputira iyo organic coating pahot-dip galvanized coilndiro rinopisa-dhipu rakavharidzirwa nemavara-rakavharwa sheet.Pamusoro pekudzivirira kwe zinc, iyo organic coating pamusoro peiyo inopisa-dip galvanized color-coated sheet inoitawo basa rekudzivirira nekudzivirira, kudzivirira ngura, uye hupenyu hwesevhisi hwakareba kupfuura iyo inopisa-dip. galvanized sheet.Iyo zinc yemukati inopisa-dip galvanized substrate inowanzoita 180g/m2 (yakapetwa kaviri), uye iyo yakanyanya zinc yemukati inopisa-dip galvanized substrate yekuvaka kunze i275g/m2.
(3) Kupisa-dip Al-Zn substrate
Pakukumbira, hot-dip galvalume coilinogona zvakare kushandiswa semavara-akavharwa substrates (55% AI-Zn uye 5% AI-Zn).
(4) Electro-galvanized substrate
Iyo electro-galvanized sheet inoshandiswa se substrate, uye chigadzirwa chinowanikwa nekuputira organic pendi uye kubheka ndeye electro-galvanized color-coated sheet.Nemhaka yokuti zinc layer ye electro-galvanized sheet yakatetepa, zinc content inowanzoita 20/20g/m2, saka chigadzirwa ichi hachina kukodzera kushandiswa.Ita madziro, matenga, nezvimwewo kunze.Asi nekuda kwechitarisiko chayo chakanaka uye mashandiro akanaka ekugadzirisa, inogona kunyanya kushandiswa mumidziyo yemumba, odhiyo, fenicha yesimbi, kushongedza kwemukati, nezvimwe.
Pamusoro yakaputirwa zvidimbu zviviri zvepende uye jira reruvara-rakaputirwa kumashure (idzi rudzi rwependi yekumashure kazhinji haina kukodzera kushandiswa kumberi)
Prepainted simbi coil (ppgi ppgl) chigadzirwa chakagadzirwa neinotonhora-yakakungurutswa simbi sheet, inopisa-dhip galvanized simbi pepa kana galvalume simbi masheets mushure mekudonha kwepamusoro, phosphating uye chromate kurapwa, uyezve yakaputirwa nependi yehupenyu uye yakabikwa.Iyo inowanzo shandiswa yakavharidzirwa yemavara yakavharidzirwa mahwendefa esimbi ndeye polyester (BHP XRW coating system, Baosteel JZ, Korea PGS, Taiwan PE), inoteverwa nesilicone resin (PSS), fluorine resin (PVDF), nezvimwewo. Ukobvu hwekuputira kazhinji 20-25μ pamusoro uye 8-10μ kumashure.Iwo anowanzo kutaurwa zviyero zvemavara-akavharwa simbi mapepa ndeaya American ASTM A527 (galvanized), ASTM AT92 (aluminium-zinc), Japanese JIS G3302, European EN/0142, Korea KS D3506, Baosteel Q/BQB420
