1.热浸镀锌。
1. Hot dip galvanizing.
因热浸镀锌具有较好的耐腐蚀性和相对较高的性能与对比,因此钢质热浸镀锌电缆桥架国内外获得广泛运用。针对厚壁及长细比较大的预制构件,在热浸镀锌时很容易产生形变等诸多问题,须在济南桥架的在结构上及镀锌工艺上进行考量。
Because hot-dip galvanizing has good corrosion resistance and relatively high performance and price comparison, steel hot-dip galvanized cable trays are widely used at home and abroad. For the prefabricated components with thick wall and large slenderness ratio, it is easy to produce deformation and many other problems during hot-dip galvanizing, which should be considered in the structure and galvanizing process of Jinan bridge.
2.电镀锌。
2. Electrogalvanizing.
电镀锌在我国有标准查询。对电镀层类型的挑选、镀层厚度、涂层附着强度、抗腐蚀实验等等都有明确规定,这种标准化的采用目标不一样,具体内容规定也存在差异。目前我国生产制造电镀锌电缆桥架生产厂家比较多,在参考运用以上相关标准规范时也有所不同。为了保证电镀锌的耐腐蚀性,能够采用电镀锌镍基合金或热镀锌之后进行高不锈钢钝化。
Electrogalvanizing is inquired in our national standard. There are clear regulations on the selection of electroplating coating type, coating thickness, coating adhesion strength, corrosion resistance test, etc. The adoption objectives of this standardization are different, and the specific contents are also different. At present, there are many manufacturers of galvanized cable tray in China, and they are also different when referring to the above relevant standards and specifications. In order to ensure the corrosion resistance of electrogalvanizing, high stainless steel passivation can be carried out after electrogalvanizing nickel-base alloy or hot galvanizing.

3.静电粉末喷涂。
3. Electrostatic powder spraying.
喷涂材料一般为聚乙烯粉末状,聚酯粉末状或防腐蚀粉末状。涂层厚度在100上下。静电粉末喷涂具备表面美观大方、防化学浸蚀性能好的特征。但是和金属镀层相比附着强度低,耐侵蚀和颗粒物损坏能力较差。使用中有质变难题,易导致部分涂层脱落,从而使得钢材基材生锈,造成镀层大规模鼓包脱落。
Spraying materials are generally polyethylene powder, polyester powder or anti-corrosion powder. The coating thickness is above 100. Electrostatic powder spraying has the characteristics of beautiful surface and good chemical etching resistance. However, compared with the metal coating, the adhesion strength is low, and the resistance to corrosion and particle damage is poor. There is a problem of quality change in use, which is easy to cause part of the coating to fall off, thus making the steel substrate rusty and causing the coating to fall off in large scale.
4.涂防腐漆。
4. Apply anti-corrosion paint.
针对截面尺寸比较大的预制构件,由于受到锌锅、镀槽、烘干箱等限定,一般只有采用涂防腐漆的方法去解决。它尽管具备低成本、方便使用等优点;但耐腐蚀功能较弱。应用周期短,维护保养工作强度大,一般不适合采用。
For prefabricated components with relatively large section size, due to the limitation of zinc pot, plating bath, drying oven, etc., generally only the method of coating anti-corrosion paint is used to solve the problem. Although it has the advantages of low cost and convenient use; However, the corrosion resistance function is weak. It is generally not suitable for use because of its short application cycle and high maintenance intensity.
5.采用铝合金制作电缆桥架,海外早就运用。不论是沿海地区含盐份地域或高环境湿度又带有二氧化硫气体地域。铝合金型材制作而成的电缆桥架,采用当然曝露,检测结果显示比钢质电缆桥架具备明显的优异的耐腐蚀性。有什么需求或者疑惑就来我们网站http://www.sddlqj.cn做咨询吧!
5. The aluminum alloy cable tray has been used overseas for a long time. No matter in coastal areas with salt content or areas with high environmental humidity and sulfur dioxide gas. The cable tray made of aluminum alloy profiles is exposed naturally, and the test results show that it has significantly better corrosion resistance than the steel cable tray.
