济南角钢镀锌起到腐蚀的目的!

来源:http://www.jnlhjscl.com/ 日期:2021-04-15 发布人:adminlehao

热镀锌角钢也叫热浸镀锌角钢或热浸锌角钢。是将除锈后的角钢浸入500℃左右融化的锌液中,使角钢表面附着锌层,从而起到防腐的目的,适用于各种强酸、碱雾气等强腐蚀环境中。
Hot dip galvanized angle steel is also called hot dip galvanized angle steel or hot dip galvanized angle steel. It is to immerse the angle steel after rust removal into molten zinc at about 500 ℃ to make the surface of angle steel adhere zinc layer, so as to achieve the purpose of anti-corrosion. It is suitable for various strong corrosive environments such as strong acid and alkali fog.
流程:热镀锌角钢工艺流程:角钢酸洗→水洗→浸助镀溶剂→烘干预热→挂镀→冷却→钝化→清洗→打磨→热镀锌完工。
Process flow: hot dip galvanized angle steel process flow: angle steel pickling → water washing → dipping auxiliary plating solvent → drying and preheating → hanging plating → cooling → passivation → cleaning → polishing → hot dip galvanizing completion.
热镀锌角钢的镀锌层厚度均匀,可达30-50um,可靠性好,镀锌层与钢材间是冶金结合,成为钢表面的一部份,因此热镀锌角钢的镀层持久性较为可靠。热镀锌角钢的原材料为角钢,所以分类于角钢相同。
The thickness of galvanized layer of hot-dip galvanized angle steel is uniform, up to 30-50um, with good reliability. The galvanized layer and steel are metallurgically combined and become a part of the steel surface. Therefore, the durability of galvanized layer of hot-dip galvanized angle steel is relatively reliable. The raw material of hot dip galvanized angle steel is angle steel, so the classification is the same as that of angle steel.

济南角钢的表面质量在标准中有规定,一般要求不得存在使用上有害的缺陷,如分层、结疤、裂缝等。
The surface quality of Jinan angle steel is stipulated in the standard. Generally, it is required that there should be no harmful defects in use, such as delamination, scarring, cracks, etc.
角钢几何形状偏差的允许范围在标准中也有规定,一般包括弯曲度、边宽、边厚、顶角、理论重量等项,并规定角钢不得有显著的扭转。
The allowable range of angle steel geometry deviation is also specified in the standard, which generally includes the items of bending degree, side width, side thickness, top angle, theoretical weight, etc., and the angle steel shall not have significant torsion.
