Analysis of Causes of Rusting of Wooden Flooring Display

Why does the wooden floor display stand rust? After many customers install the wooden floor display stand, the wooden floor display stand will appear rusty and peeling after using it for one or two years. Customers are confused about why this phenomenon still occurs during normal use. The following is an analysis of the reasons.

1. The quality of the display rack steel

Generally, the cost of steel accounts for a large part of the sales price of display racks. Therefore, in order to make display racks cheaper, some wooden flooring display rack manufacturers reduce the total cost of display rack projects by reducing the amount of steel used in display racks. On the other hand, the showroom display stand is produced by using thin plates rolled by a small, cheap and inferior rolling mill. Small rolling mills lack equipment and require multiple heating to make a roll of material. It is difficult to control the temperature of steel during multiple heating processes. The mechanical properties of different parts of the material will be different, and the Fe-C crystal will produce diversity and instability. The surface density of the material is poor, and the corrosion resistance is weak.

2. The spraying process of the display rack

The spraying process of wooden floor display racks often needs to go through 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 temperature of the water, and the temperature of the drying room, which require very good control. If the equipment is not advanced enough is an objective problem, then subjectively destroys the normal process, the purpose is to reduce the cost of display stand for shop by reducing procedures and shortening processing time. However, product quality cannot be guaranteed in this way. 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. This reminds the purchaser to not only decide the supplier based on the price when purchasing the wooden floor display stand, but to choose a reliable display stand company. Choose reliable suppliers according to the strength of each company.
