钢结构螺栓表面常见处理方法

钢结构螺栓表面处理常常会分为两个镀锌方式,一种是热镀锌这是一种比较常见的一种古老的一种镀锌方式,还有一种表面处理方式就是达克罗了,常规的镀锌一般都会选择热镀锌方式进行钢结构螺栓表面上,既能在有效的时间里面保证螺栓不被腐蚀又能保证自己工程上的质量度。而达克罗就比热镀锌要贵得多,这种达克罗处理过的钢结构螺栓能够比热镀锌多几十年的时间,这个具体时间要根据实际情况进行操作了。

The surface treatment of steel structure bolts is often divided into two ways, one is hot-dip galvanizing, which is a relatively common ancient way of galvanizing, and the other is Dacromet. The conventional galvanizing method is usually hot-dip galvanizing on the surface of steel structure bolts, It can not only ensure that the bolt is not corroded in the effective time, but also ensure the quality of the project. Dacromet is much more expensive than hot-dip galvanizing. This kind of Dacromet treated steel structural bolts can last several decades longer than hot-dip galvanizing. This specific time should be operated according to the actual situation.
体现在钢结构螺栓所处在的环境中,有一些恶劣的环境会造就有一些螺栓本来有效年限能够达到50年,实际使用不到一般就要更换其固定的螺栓了。这就要根据实际的情况下选择适合自己表面处理的螺栓了。
Reflected in the environment of steel structure bolts, there are some bad environment will make some bolts have been valid for 50 years, the actual use of less than generally need to replace the fixed bolts. This is based on the actual situation to choose suitable for their own surface treatment of the bolt.
其他常见的螺栓表面处理:
Other common bolt surface treatment:
一,紧固件的电镀紧固件的电镀就是指将紧固件中必须被电镀的一部分渗入特殊的溶液中,溶液里会带有一些堆积的金属材料化学物质,那样在以电流量根据溶液后,溶液内的金属材料化学物质溶解并粘附在紧固件的渗入一部分上。紧固件的电镀一般包含热镀锌、铜、镍、铬、铜镍合金等。
1、 Electroplating of fasteners electroplating of fasteners refers to the infiltration of a part of fasteners that must be electroplated into a special solution, in which there will be some accumulated metal material chemicals. In this way, the metal material chemicals in the solution will dissolve and adhere to the infiltrated part of fasteners after the current is applied to the solution. Electroplating of fasteners generally includes hot-dip galvanizing, copper, nickel, chromium, copper nickel alloy, etc.
二,紧固件的热浸镀锌紧固件的热浸镀锌是将碳素钢成分的紧固件渗入到关注度约为510℃的熔化锌的镀槽体,那样紧固件表面上的铁锌合金材料会变化为钝化处理锌,进而得到表面处理实际效果。紧固件的热浸镀锌解决价钱要高过电镀,约为1公斤1.5到2元。
2、 The hot-dip galvanizing of fasteners is to infiltrate the carbon steel fasteners into the molten zinc plating bath with a degree of concern of about 510 ℃, so that the iron zinc alloy material on the fastener surface will change to passivation treatment zinc, and then get the actual effect of surface treatment. The price of hot-dip galvanized fasteners is higher than that of electroplating, which is about 1.5 to 2 yuan per kilogram.
三,紧固件的机械设备镀紧固件的机械设备镀,是指采用特殊的物理和有机化学方法,用涂层金属材料的粉末,对紧固件的表面进行冲击,如用涂层金属材料按冷焊的方式,在紧固件表面形成镀层,达到表面处理的实际效果。紧固件的机械设备镀关键适用螺丝、螺丝帽和密封垫等配件
3、 Mechanical equipment plating of fasteners mechanical equipment plating of fasteners refers to using special physical and organic chemical methods to impact the surface of fasteners with the powder of coated metal materials, such as using coated metal materials to form coating on the surface of fasteners by cold welding, so as to achieve the actual effect of surface treatment. The key parts of mechanical equipment for fasteners are screws, screw caps and gaskets
