济南C型钢讲解钢结构加工日常维护技巧

济南C型钢防锈方法,根据钢材的锈蚀机理,钢材的防锈方法分为4种。一是改变钢材的组成结构。即在钢材的冶炼过程中计入铜、铬等合金元素以提高钢材的抗锈能力,此即不锈钢,由于造价太高,难在工程中大量应用。
Anti rust method, according to the corrosion mechanism of steel, steel rust method is divided into 4 kinds. One is to change the composition of steel. That is, in the process of steel smelting process, such as copper, chromium and other alloy elements to improve the ability to resist rust, this is stainless steel, because the cost is too high, it is difficult to apply in a large number of projects.
目前仅用于小型装饰性的工程。二是阴极保护法,即将构件与电源阴极相连,使构件失去的电子得到补充,钢材内部始终维持电位平衡而不生锈。
Currently only used for small decorative works. Two is the cathodic protection method, the component and the power cathode is connected, so that the electronic components of the lost, the internal steel has always maintained the potential balance without rust.

此方法目前仅用于对水下或水下结构的保护。三是在构件表面用金属覆盖层保护,如电镀或热侵镀锌等方法,一般用于薄板材或小直径装饰性管材,如网架用钢管。
This method is currently only used for the protection of water or underwater structures. Three is in the component surface with metal coating protection, such as electroplating or hot dip galvanized, etc., generally used for thin plate or small diameter decorative pipe, such as steel pipe.
四是在钢材表面喷涂以非金属保护层,隔断钢材于空气的接触而达到防锈的目的,此方法施工方便,造价比较低,所以在工程中广告应用,单耐久性差,一般几年后须要再次喷涂。
Four is in the steel surface coating to non-metallic protective layer, cut off the steel in air contact and achieve the purpose of anti rust, this method is convenient, cost is relatively low, so in the engineering application of advertising, single durability is poor, in general a few years later need to re spray.
