When it comes to Shandong cable bridge, we should be familiar. With the improvement of people's living standards, the use of cable tray is becoming more and more extensive. With the growth of time, the cable tray will also be damaged. Next, Kaichen Bridge Company will take you to understand the method of prolonging the service time of cable tray, hoping to help you!
1. Hot dip galvanizing
Hot dip galvanizing is a way to maintain negative Ji metal materials as a negative Ji protection. Its anti-corrosion service life is due to the thickness of hot-dip galvanized coating and convective heat transfer coefficient. The thickness of zinc coating of hot-dip galvanizing is generally above 65um (453g / m2). The fusion surface of zinc and iron produces a layer of zinc non-ferrous metal, which improves the adhesion of zinc layer. It is very easy to cause deformation and other problems in hot-dip galvanizing, which should be considered in the structure of cable tray and hot-dip galvanizing process.

2. Phosphating treatment
Compared with hot-dip galvanizing, phosphating treatment has the advantages of simple processing technology and low cost. There are no special requirements for the structure of cable tray in Shandong Province. The results show that phosphating treatment can obviously improve the maintenance characteristics of stainless steel after passivation. The phosphating layer is generally above and below 12 / ZM. Therefore, the sense of discomfort is used to resist corrosion in places with high service life.
3. Electrostatic powder spraying
The raw materials for painting are generally polyethylene powder, polyester powder or anti-corrosion powder. The thickness of the coating is about 100 / 1RN. Electrostatic powder spraying has the characteristics of beautiful surface and good chemical corrosion resistance.
4. Apply anti-corrosion paint
Due to the limitation of zinc pot, plating bath and drying box, anticorrosive paint is usually used to solve the problem of prefabricated components with large construction specifications. Although it has the characteristics of low cost and convenient use, its corrosion resistance is weak. The application cycle is short and the maintenance labor is large.
If you want to use the cable tray for a longer time, and the maintenance of the cable tray is also inseparable, next, let's take a look at the maintenance methods of the cable tray!
1. For routine maintenance, we can use clean thin cloth to wipe the dust on the surface habitually, and do not use wet cloth or hard block to wipe the surface of varnish, bathroom mirror and laminated glass, and do not touch with acid, alkali organic chemical objects and greasy substances.

2. Regular maintenance can be carried out once a quarter at key points. After wiping the dust on the surface with soft cotton cloth, the surface should be evenly smeared with special polishing oil wax, and then the cleaning thin cloth should be used to brighten and waterproof. Hardware accessories, metal door handle can be wiped and wiped with less car oil, so that it can be turned over easily, antirust treatment and oxidation resistance.
3. Prevent it from being placed in high temperature and humid areas, so that you can persevere and the natural ventilation of the house is boring.
4. The cable tray shall be prevented from touching corrosive liquids, such as ethanol and acid substances.
5. Use dry and clean thin cloth and special maintenance wax.
The above is the introduction of Shandong cable bridge maintenance and anti-corrosion methods, according to the above methods can extend the use of cable tray, I believe that through the description of this article, you can have a certain understanding and understanding of the anti-corrosion and maintenance of cable tray, hope the above content can help you.
