Why Does The Flooring Display Rack Rust?

View:2502/12/2020  

Why does the flooring display rack rust? After many customers install the flooring display rack, they will show the phenomenon of rust and peeling in 1 or 2 years. Why does the normal use of the flooring display rack show this phenomenon? The customers are very depressed. Today, I'm here to analyze the reason for the disturbed customers.


1. Steel Quality Problems Of Flooring Display Rack

Steel Quality Problems Of Flooring Display Rack

The cost of ordinary steel accounts for a large part of the sales price of the exhibition stand. Therefore, in order to make the exhibition stand look more "cheap", some floor display stand manufacturers reduce the total cost of the exhibition stand project by reducing the amount of steel used for the exhibition stand; on the other hand, they use the cheap and inferior sheet rolled by small rolling mills to consume the exhibition stand. However, small rolling manufacturers lack of equipment, so they need to stop heating repeatedly to form a roll of materials. In the process of heating repeatedly, the temperature of the steel is difficult to be well controlled, and the mechanical properties of different parts of the materials will be different. At the same time, the Fe-C crystal understands the diversity and instability, the density level of the data surface is poor, and the corrosion resistance can be weak.


2. Spraying Technology Of Flooring Display Rack


Flooring display rack spraying process often needs to go through the following steps: derusting, degreasing, phosphating treatment, water cleaning, drying, electrostatic powder spraying, hot melting, curing, etc. These steps have strict requirements on the control of disposal time of each process, concentration of phosphating solution, water temperature, temperature of drying room, etc., which requires very good control. If the equipment is not advanced enough, then it is an objective problem to destroy the normal process objectively. The purpose is to reduce the cost of exhibition by reducing the process and disposal time. But this does not guarantee the quality of production. Taking phosphating as an example, to reduce this process, powder spraying can still be completed, and it is difficult to see the problem in a short time.
