Why does the wooden floor display rack rust? Many customers will experience rust and peeling after using the wooden floor display rack for one or two years. Why does this phenomenon occur in normal use? The customers are very depressed. Today, I will analyze the reasons for the troubled customers.

1. The quality of display rack steel

Generally steel costs account for a large part of the sales price of display racks. Therefore, in order to make the display racks more "cheap", some wooden floor display rack manufacturers reduce the total cost of the display rack project by reducing the amount of steel used in the display rack; on the other hand, they use cheaper Inferior small rolling mills rolled thin plates to produce display stands. However, small rolling mills lack equipment. To form a roll of material, it needs to be heated multiple times. In the process of multiple heating of steel, it is difficult to control the temperature well, and the mechanical properties of different parts of the material will have certain differences. Fe-C crystals will produce diversity and instability, the surface of the material is poorly dense, and the corrosion resistance is weak.

2. The spraying process of the display rack

The spraying process of wooden floor display racks often requires the following steps: rust removal, degreasing and degreasing, phosphating treatment, water cleaning, drying, electrostatic powder spraying, hot melting, curing, etc. These steps have strict requirements on the control of the processing time of each process, the concentration of the phosphating solution, the water temperature, the temperature of the drying room, etc., which require very good control. If the equipment is not advanced enough is an objective problem, then go up subjectively The purpose of destroying the normal process is to reduce the cost of the display rack by reducing the process and shortening the processing time. But doing so does not guarantee product quality. Taking phosphating as an example, to reduce this process, powder spraying can still be completed, and it is difficult to see the problem in the short term.

The above two aspects are the main reasons for the rust and peeling of the surface of the wooden floor display rack. I hereby remind the purchaser not to decide the supplier solely based on the price when purchasing the wooden floor display rack, but to choose a reliable display rack company, comprehensively The strength of the company chooses to determine a reliable supplier.
