热浸锌工艺
Hot dip galvanizing process
锌具有杰出的耐腐蚀性,浸锌作为一种献身阳极来维护阴极金属的办法,电缆桥架厂家取决于它的腐蚀锌镀层的阻力和腐蚀速度。热浸锌的锌层厚度通常在6μm以上,锌与铁的结合面构成一层锌铁合金,提高了锌层的粘附性。
Zinc has excellent corrosion resistance. As a way to dedicate the anode to maintain the cathode metal, the cable tray manufacturer depends on the resistance and corrosion rate of its corrosive zinc coating. The zinc layer thickness of hot-dip galvanizing is usually 6 μ M above, the interface between zinc and iron forms a layer of zinc iron alloy, which improves the adhesion of the zinc layer.
电缆桥架厂家由于热浸锌具有杰出的耐腐蚀性、高功能和比,因而热浸锌钢桥被广泛运用于国内外。热浸锌不易变形等问题,需要在电缆桥架的构造上及浸锌技术上加以思考。
The hot-dip galvanized steel bridge is widely used at home and abroad because of its outstanding corrosion resistance, high function and price ratio. Hot dip galvanizing is not easy to deform, which needs to be considered in the structure of cable tray and galvanizing technology.
电镀锌工艺
Galvanizing process
对于没有特殊要求的电缆桥架来说,电镀锌与热浸锌比较起来技术简单,本钱较低。电镀锌经钝化处理后能够显着地提高其防腐功能。电镀锌层通常在6μm左右,因而不适用于对耐腐蚀要求较高的场合。
For cable trays without special requirements, electro galvanizing and hot-dip galvanizing are simple in technology and low in cost. After passivation treatment, galvanizing can significantly improve its anti-corrosion function. The electro galvanized coating is usually at 6 μ M, so it is not suitable for occasions requiring high corrosion resistance.
电镀锌我国有颁布标准:如GB/T13912-2002、JT/T281-95、GB2694-81等。挑选电镀层时,涂层厚度,涂层吸附力强,通过耐腐蚀实验,不同的诉求对于目标的选择也是不同的。我国现在生产镀锌桥架的厂家,在参考国标时也不尽相同。
China has issued standards for electro galvanizing, such as gb/t13912-2002, jt/t281-95, gb2694-81, etc. When selecting electrodeposited coating, the coating thickness and coating adsorption are strong. Through the corrosion resistance test, different demands have different choices for the target. At present, the manufacturers of galvanized cable tray in China are not the same when referring to the national standard.
山东桥架
粉末喷涂工艺。
Powder spraying process.
山东桥架厂家提醒您,有用的材料通常是粉末涂料,聚酯粉末或防腐粉末,涂层厚度约60μm。静电喷涂具有外形漂亮,抗化学腐蚀杰出的功能。但与金属镀层比较,粘附性低,耐脏性和耐磨损较差。遭受简单外部撞击,可致使其局部涂层掉落,使得内部钢材腐蚀,形成大面积涂层起泡脱皮。
Shandong bridge manufacturer reminds you that the useful materials are usually powder coating, polyester powder or anti-corrosion powder, with a coating thickness of about 60 μ m。 Electrostatic spraying has beautiful appearance and outstanding chemical corrosion resistance. However, compared with metal coating, it has low adhesion, poor dirt resistance and wear resistance. A simple external impact may cause the local coating to fall, causing the internal steel to corrode and forming a large area of coating blistering and peeling.
涂防锈漆。
Apply antirust paint.
较大尺寸的构件,由于镀锌设备条件所限,通常只能选用涂防锈漆的办法来处理。这当然具有本钱低,方便等优势,但防腐蚀性能较差。其工程短暂,为了确保工程质量,通常不宜运用。
Due to the limited conditions of galvanizing equipment, the components with large size can only be treated by coating antirust paint. This of course has the advantages of low cost and convenience, but the corrosion resistance is poor. The project is short, so it is usually not suitable for use in order to ensure the project quality.
其他无机涂料涂敷。
Application of other inorganic coatings.
AB-2型防火堵料为柔性防腐材料,遇火后碳化形成坚固的阻火隔热层。产品具有良好的可塑性和耐腐蚀、耐火、耐油等特性。AB-1型无机防火堵料是一种以无机防火材料为主的防火材料,粉状适用于电力、石化、冶金、建筑等行业电缆桥架的涂敷。
Ab-2 type fireproof plugging material is a flexible anti-corrosion material, which is carbonized to form a solid fire resistance and insulation layer in case of fire. The product has good plasticity, corrosion resistance, fire resistance, oil resistance and other characteristics. AB-1 inorganic fireproof plugging material is a kind of fireproof material mainly composed of inorganic fireproof materials. The powder is suitable for the coating of cable trays in electric power, petrochemical, metallurgy, construction and other industries.
