Signal light pole manufacturers share the signal lamp post processing of cold galvanized and hot

Signal light pole cold galvanized and hot dipped galvanized for corrosion protection, extend the lamp life use, what is the difference between them? The following signal light pole manufacturer - - Huasheng new energy is to say with you the specific signal lamp post processing and the difference between cold galvanized and hot dip galvanized

 signal light pole cold galvanizing 【 Cold galvanizing is through electrochemical principle of a kind of technology for workpiece surface anti-corrosion treatment. 】 And hot dip galvanized Hot dip galvanized, 镀锌) Also called hot dipping zinc and hot galvanizing, is an effective way of metal corrosion, mainly used for metal structure industry facilities. 】 For corrosion protection, extend the use of street lamp life, what is the difference between them? The following signal light pole manufacturer - - New energy is to say with you the specific signal lamp post processing of cold galvanized and hot dip galvanized difference: the difference of one process: cold galvanizing is also called the galvanized Electricity galvanized, industry also called cold galvanizing, is to make use of electrolysis on surface formation uniform, dense, combined with the good process of metal or alloy deposits. 】 Is using electrolytic equipment after the workpiece through the degreasing, pickling into the composition of zinc salt in the solution, and join the cathode electrolytic equipment, zinc plate is placed in the workpiece on the opposite side of cohesion in anode electrolytic equipment, connected to the power supply, using the current from the positive to the negative of directional movement, will accumulate a layer of zinc on the workpiece. Hot galvanizing is the workpiece degreasing, pickling, leaching, drying after immersed in molten zinc liquid must moment, free to ask. Second appearance difference: electric galvanized seem more lubrication, bright, choose the electric plating of the colorful passivation technology chartreuse give priority to color, colorful. Use white passivation technology of galvanized coating is bluish white or white with green, white passivation process of coating and the sunlight is must point slightly. In mixed and disorderly the Angle of the workpiece edge areas prone to 'coagulator and become dim, the zinc layer is thicker. In internal Angle place is easy to form the current death jiao and owe current dim area, the zinc layer is thinner. Without zinc tumor, agglomerate phenomenon such as integral parts. Hot dip galvanized appearance is a little rough, galvanized is silvery white, look likely to happen process water lines and a few drops of tumor, especially in one end of the workpiece is more obvious. However, slightly rough, hot dip galvanized zinc layer is thicker than the electric galvanized dozens of times, anti-corrosion function is electric galvanized dozens of times, on the price nature also is much taller than cold galvanizing, but in the long run, rust for more than 10 years of hot dip galvanized than only 1 - 2 years of cold galvanizing popular antirust effect. Above is the signal light pole manufacturer - - New energy release. Zhongshan new energy co. , LTD. , mainly produces steel bar equipment, can produce conical rod and prismatic bar, automatic coating equipment, meet all kinds of steel bar surface polyester coating. Look forward to cooperation with you.
