槽钢,如今很多场合都会运用到,但很多人都不了解它具备的特征,那么镀锌槽钢有什么特征呢?怎么断定镀锌槽钢的好坏呢?下面由小编为大家详细介绍一下。

Channel steel, now many occasions will be used, but many people do not understand the characteristics of it, then what is the characteristics of galvanized channel steel? How to determine the quality of the galvanized channel steel? The following is a detailed introduction to you.

1、具有较厚的细密的纯锌层掩盖在钢铁外表上,它可以防止钢铁基体与任何的腐蚀溶液的触摸,维护钢基体免受腐蚀。在通常空气中,锌层外表构成一层很薄而密实的氧化锌层外表,它很难溶于水,故对钢基体起着必定维护效果。假如氧化锌与空气中其它成分生成不溶性锌盐后,则防蚀效果更抱负。

1, the thicker, pure zinc coating is covered on the surface of steel, it can prevent the touch of steel matrix from any corrosive solution, and protect the steel matrix from corrosion. In the usual air, the surface of the zinc layer forms a thin and dense layer of Zinc Oxide layer. It is difficult to dissolve in water, so it has a certain maintenance effect on the steel matrix. If Zinc Oxide and other ingredients in the air produce insoluble zinc salt, the anticorrosion effect is more ambitious.

2、具有铁—锌合金层,联系细密,在海洋性盐雾空气及工业性空气中体现特有抗腐蚀性;

2, with iron - zinc alloy layer, contact fine, in the sea of salt fog air and industrial air to reflect the unique corrosion resistance;

3、因为联系结实,锌—铁互溶,具有很强的耐磨性;

3, because the connection is strong, zinc - iron is intersoluble, and has strong wear resistance.

4、锌具有杰出的延展性,其合金层与钢基附着结实,因而热镀件可进行冷冲、轧制、拉丝、曲折等各种成型而不损坏镀层;

4, zinc has excellent ductility. Its alloy layer is strongly adhered to the steel substrate, so hot plating can be molded by cold stamping, rolling, drawing and winding, without damaging the coating.

5、钢构造件热镀锌后,适当于一次退火处理,能有效改进钢基体的机械性能,消除钢件成型焊接时的应力,有利于对钢构造件进行车削加工。

5, after hot galvanizing of steel structure, proper annealing treatment can effectively improve the mechanical properties of the steel matrix, eliminate the stress during welding and welding of steel structures, and facilitate the turning of steel structures.

6、热镀锌后的件外表亮光漂亮。

6. The parts after hot dip galvanizing are bright and beautiful.

7、纯锌层是热镀锌中最赋有塑性的一层镀锌层,其性质根本接近于纯锌,具有延展性,所以它富于挠性。

7, the pure zinc layer is the most plastic layer of galvanized zinc layer in hot dip galvanizing, its properties are basically close to pure zinc, with ductility, so it is flexible.
