Surface treatment of river mesh fence

Aug 22, 2019
Several surface treatment methods are combined and compared, it can be said that the cost of electroplating zinc is relatively low, but accompanied by poor scratch resistance. The hot-dip galvanized river guardrail has a thicker zinc layer and a longer anti-oxidation time, and has better anti-corrosion and anti-rust results. Therefore, the manufacturer believes that it is more important to choose the appropriate method and then deal with it when choosing to handle the surface of the guardrail.

Treatment method 1, electro-galvanized treatment. As the name implies, the electroplating zinc treatment method refers to the use of electrolysis equipment to remove the oil, pickle, and then put into the solution of zinc salt, and connect the negative electrode of the electrolysis equipment, place the zinc plate on the opposite side of the pipe, and connect it to the electrolysis equipment. The positive pole is energized, and a layer of zinc is deposited on the tube by utilizing the current to move from the positive pole to the negative pole.
 
Treatment method 2, hot-dip galvanizing treatment. This treatment method mainly involves immersing the rust-removed steel member in the zinc liquid melted at about 500 ° C to adhere the zinc layer on the surface of the steel member, thereby preserving the purpose of corrosion prevention.
 
Treatment method three, spray plastic. This treatment means spraying plastic powder on the guardrail and its parts. It uses an electrostatic generator to charge the plastic powder, adsorb it on the surface of the iron plate, and then bake at 180-220 ° C to melt and adhere the powder to the metal surface. This treatment method has no pollution to the environment, and the coating has excellent appearance quality, and also has strong adhesion and mechanical strength.
