What is FRP cable tray?
Glass fiber reinforced plastic cable tray is a multifunctional and high-efficiency power auxiliary equipment glass fiber reinforced plastic cable tray. Now it has become the main product used in supporting electrical and electronic equipment. When laying cables, it is very suitable to use closed trough bridges. Gravity cables and ladder-type fiberglass bridges where cables with large spans need to be laid are light in weight, high in hardness, and high in pultrusion. It is more powerful, has a variety of effects of compression and resistance to corrosion, and can be used to reflect these advantages when used in organic solvents such as acids and alkalis. It also has the function of insulation and flame retardant, which can avoid the metal fence The heat generated by electromagnetic induction under high electromagnetic field and high induced voltage will not cause damage to the transformer equipment, can protect the construction personnel, avoid the danger of being shocked, and the aging resistance is also very good. It will oxidize and rust, and will not fade. It does not need to be painted for maintenance, and it does not need to be maintained in normal times. People carry out regular maintenance. It is also relatively plastic. After being impacted by objects, it can return to its original shape. The glass fiber reinforced plastic bridge mainly has the above advantages, which makes it play a very large role in the work process and achieves a very Good use effect.
It is the specific gravity of the passivation film that is greater than the specific gravity of the substrate. These two characteristics indicate that the passivation film is thin and dense. Therefore, the passivation film is difficult to be penetrated by the corrosive medium to quickly etch the substrate. The third characteristic is The chromium concentration of this passivation film is more than three times higher than that of the substrate. Therefore, the passivation film has high corrosion resistance, and the application of chemical element stainless steel is extremely complicated.
Stainless steel bridge is a kind of highly corrosion-resistant bridge. The reason for the corrosion resistance of stainless steel bridge is that stainless steel contains various small elements. Passivation film theory The basic reason (mechanism) of the corrosion resistance of stainless steel bridges is the theory of passivation film. The so-called passivation film is a film mainly composed of cr203 on the surface of stainless steel. Beautiful appearance, convenient installation, long service life, epoxy resin and epoxy resin composite cable trays are suitable for use in strong corrosive environments, large spans, and heavy loads. Therefore, it is necessary to add steel to the steel according to different conditions. Molybdenum, copper, nitrogen and other alloy elements, with the composition of the passivation film, further the corrosion resistance of stainless steel, the corrosion resistance of stainless steel cable trays are conditional, and a brand of stainless steel is resistant to corrosion in a certain medium.
