Akwụkwọ igwe galvanized A kọwapụtara dịka mpempe akwụkwọ nchara carbon nke ejiri zinc kpuchie n'akụkụ abụọ. Galvanized Steel eriri igwe mepụta galvanized ígwè na abụọ isi usoro: na-aga n'ihu na-ekpo ọkụ itinye galvanizing na electro galvanizing.
Nkọwa nke eriri igwe galvanized nke anyị nwere ike inye:
1) Standard: JIS G3302 1998, ASTM A653M / A924M 2004, niile dị ka ndị ahịa arịrịọ.
2) ọkwa: SGCC, SGCH, DX51D, Q195, Q235 niile dị ka ndị ahịa arịrịọ
3) Ike: banyere 12000 ton kwa ọnwa

6) eriri igwe ID: 508mm
7) Igwe mkpuchi mkpuchi: site na 2-10MT, dị ka arịrịọ onye ahịa si dị
8) Zinc mkpuchi ibu: 40g / m2-275g / m2
9) Spangle: spangle mgbe niile, nnukwu spangle, obere spangle na spangle efu
10) Ngwọta elu: Kemịkalụ passivating, mmanụ, mmanụ passivating, akpụkpọ gafere
11) Nri: igwe igwe, mbepu onu
12) Usoro nnwale nke 25 ton nke ọ bụla
Ngwa nke eriri igwe galvanized anyị:
1.Construction na ụlọ: roofing; ikuku ventilashion; aka aka; nkebi panel, wdg.
2.Nhazi ọzọ: mkpuchi isi efere.
3.Electric ngwa: refrjiraeto; igwe na-asa akwa; onye na-edekọ ihe; microwave, wdg.
Usoro ntinye na-ekpo ọkụ na-agụnye ịgafe nchara site na bat zinc a wụrụ awụ, na usoro electro galvanizing gụnyere itinye zinc site na ọgwụgwọ electrolytic. N'ihi ya, a na-ejikọta oyi akwa zinc nke ọma na metal ntọala site na akwa mkpuchi ígwè-zinc. A na-arụpụta ngwaahịa anyị na-ekpo ọkụ na-ekpo ọkụ na-adabere na nkọwapụta, na ngwaahịa electro-galvanized anyị na-agbaso nkọwa.
Galvanizing bụ otu n'ime ụzọ kachasị dị irè na nke akụ na ụba maka ichekwa igwe anaghị agba nchara site na gburugburu ndị na-emebi emebi. Zinc abụghị naanị ihe mgbochi n'etiti ígwè na gburugburu ebe obibi, ma na-achụkwa onwe ya àjà iji chebe efere ígwè dị n'okpuru ebe a.
