熱鍍鋅角鋼
鎖定
熱鍍鋅角鋼也叫熱浸鍍鋅角鋼或熱浸鋅角鋼。是將除鏽後的角鋼浸入500℃左右融化的鋅液中,使角鋼表面附着鋅層,從而起到防腐的目的,適用於各種強酸、鹼霧氣等強腐蝕環境中。

熱鍍鋅角鋼工藝流程
熱鍍鋅角鋼工藝流程:角鋼酸洗-水洗-浸助鍍溶劑-烘乾預熱-掛鍍-冷卻-鈍化-清洗-打磨-熱鍍鋅完工。熱鍍鋅角鋼的鍍鋅層厚度均勻,可達30-50um,可靠性好,鍍鋅層與鋼材間是冶金結合,成為鋼表面的一部份,因此熱鍍鋅角鋼的鍍層持久性較為可靠。
熱鍍鋅角鋼主要分類
熱鍍鋅角鋼的原材料為角鋼,所以分類與角鋼相同。按工藝分類可分為熱鍍鋅熱軋角鋼和熱鍍鋅冷軋角鋼。市場常見的是熱軋的熱鍍鋅角鋼。熱鍍鋅冷軋角鋼,一般需要根據用户需求用冷軋板定製。按邊長可分為熱鍍鋅等邊角鋼和熱鍍鋅不等邊角鋼。
熱鍍鋅角鋼主要優點
1、處理費用低:熱浸鍍鋅防鏽的費用要比其他漆料塗層的費用低;
2、持久耐用:熱鍍鋅角鋼具有表面光澤,鋅層均勻,無漏鍍,無滴溜,附着力強,抗腐蝕能力強的特性,在郊區環境下,標準的熱鍍鋅防鏽厚度可保持50年以上而不必修補;在市區或近海區域,標準的熱鍍鋅防鏽層則可保持20年而不必修補;
3、可靠性好:鍍鋅層與鋼材間是冶金結合,成為鋼表面的一部份,因此鍍層的持久性較為可靠;
4、鍍層的韌性強:鍍鋅層形成一種特別的冶金結構,這種結構能承受在運送及使用時受到機械損傷;
5、全面性保護:鍍件的每一部分都能鍍上鋅,即使在凹陷處、尖角及隱藏處都能受到全面保護;
6、省時省力:鍍鋅過程要比其他的塗層施工法更快捷,並且可避免安裝後在工地上塗刷所需的時間。
熱鍍鋅角鋼應用領域
廣泛運用與電力鐵塔、通信鐵塔、鐵路、公路防護、路燈杆、船用構件、建築鋼結構構件、變電站附屬設施、輕工業等。
