1. Igikorwa cyo gukora icyapa cyamabara
Icyapa cy'amabara (kizwi kandi nk'icyapa cy'amabara, icyuma gisize amabara,ppgi ppgl.
Imiterere yo gutwikamo ikubiyemo amakoti abiri hamwe no guteka, amakoti abiri hamwe nudutsima tubiri, nibindi.
Igikorwa nyamukuru cyo gukora cyibisanzwe bibiri-bitwikiriye hamwe nuburyo bubiri bwo guteka bikomeza ibara ryamabara ni: uncoiler ------- imashini idoda ------ gukanda roller ------ imashini itera --- -Gufungura Looper ----- Kugabanuka kwa Alkaline ---- Gusukura ---- Kuma ----- Passivation ----- Kuma ------ Gutangira gutwikira ------- gutwika bwa mbere na kuma umuzingo ukurikira urapakirwa ugashyirwa mububiko).
Ibisanzwe bisanzwe kumabara yicyuma (ppgi ppgl coil)
(1) Ubukonje bukonje
Isahani yamabara ikozwe mubukonje bukonje ifite isura nziza kandi nziza kandi ifite uburyo bwo gukora isahani ikonje;icyakora, ibishushanyo bito byose mubitwikiriye hejuru bizashyira hejuru yubukonje bukonje mukirere, bizahita byerekana ibyuma kuri Generate itukura.Kubwibyo, ibicuruzwa nkibi birashobora gukoreshwa gusa mubikorwa byo kwigunga byigihe gito nibikoresho byimbere hamwe nibisabwa bike.
(2) Gushyushya gushyushya substrate
Ibicuruzwa byabonetse mugutwikira ibinyabuzima kuribishyushye-bishyushyeni ashyushye-dip galvanised ibara-ryuzuye.Usibye ingaruka zo kurinda zinc, gutwika kama hejuru yurupapuro rushyushye rwamabara ashyushye kandi bigira uruhare mukurinda no gukingira, kwirinda ingese, kandi ubuzima bwumurimo burebure kuruta ubw'ubushyuhe-dip urupapuro.Ibirimo bya zinc biri munsi yubushyuhe-bushyushye ni 180g / m2 (impande zombi), naho zinc ntarengwa yibintu bishyushye byubatswe hanze ni 275g / m2.
(3) Ashyushye-Al-Zn substrate
Bisabwe, hot-dip galvalume coilirashobora kandi gukoreshwa nkibara risize amabara (55% AI-Zn na 5% AI-Zn).
(4) Substrate ya elegitoronike
Urupapuro rwa electro-galvanised rukoreshwa nka substrate, kandi ibicuruzwa byabonetse mugusiga irangi kama no guteka ni urupapuro rwamabara.Kuberako urwego rwa zinc rwurupapuro rwa electro-galvanised ruba ruto, ibirimo zinc mubisanzwe 20 / 20g / m2, kubwibyo bicuruzwa ntibikwiriye gukoreshwa.Kora inkuta, ibisenge, nibindi hanze.Ariko kubera isura nziza nuburyo bwiza bwo gutunganya, irashobora gukoreshwa cyane mubikoresho byo murugo, amajwi, ibikoresho byuma, imitako yimbere, nibindi.
Ubuso bwo hejuru butwikiriye ibice bibiri by'irangi hamwe n'urwego rusize amabara hejuru yinyuma (ubu bwoko bwirangi bwinyuma ntibukwiriye gukoreshwa imbere)
Igicapo cyateguwe (ppgi ppgl) nigicuruzwa gikozwe mu cyuma gikonjesha gikonje, icyuma gishyushye cyane cyangwa impapuro za galvalume nyuma yo kwangirika hejuru, kuvura fosifati na chromate, hanyuma ugasiga irangi kama hanyuma ukateka.Ibikoresho bisanzwe bikoreshwa mubyuma bisize amabara ni polyester (sisitemu yo gutwikira BHP XRW, Baosteel JZ, Koreya PGS, Tayiwani PE), ikurikirwa na silicone resin (PSS), fluor resin (PVDF), nibindi. Ubunini bwa coating muri rusange ni 20-25μ hejuru na 8-10μ inyuma.Ibipimo bikunze kuvugwa kumpapuro zometseho amabara ni Amerika ASTM A527 (galvanised), ASTM AT92 (aluminium-zinc), Ikiyapani JIS G3302, Abanyaburayi EN / 0142, Koreya KS D3506, Baosteel Q / BQB420
