How to distinguish the quality of color stainless steel plate?

Because of its bright color, good workability, good corrosion resistance and formability, colored stainless steel sheet has been widely used in many stainless steel home improvement and commercial decoration projects. How to distinguish whether a color stainless steel plate is good or bad? BAOBIN STEEL stainless steel plate manufacturers believe that there are the following aspects to identify the color stainless steel plate.

1. Plate type:

A good color stainless steel sheet should have good diagonal tolerance and flatness, which can be measured with a pull gauge and a feeler gauge. If the plate shape is poor or the diagonal is out of tolerance, it will have a greater impact on the product accuracy after shearing and bending, thus affecting the installation accuracy and appearance.

2. Color difference:

The editor takes the titanium plate made by vacuum ion plating as an example. At present, the most commonly used processing method for vacuum electroplating in the stainless steel industry is vacuum ion sputtering. The commonly used equipment is divided into vertical furnaces and horizontal furnaces, which can be divided into large furnaces and small furnaces according to specifications. Generally speaking, in addition to the advanced nature of the equipment body, the daily management and monitoring of the equipment, the level of the operators, the scientificity and effectiveness of the detection methods of the detection tools, the plating time, the reasonable selection of titanium blocks, etc. All are the influencing factors of whether the color difference of a titanium plate is good or bad.

For example, the color difference inspection method of titanium plate is mainly detected by a colorimeter, and the titanium plate produced by a good manufacturer uses a colorimeter for five-way average color difference inspection. The A value, B value and L value of the four corners of the plate and the plate can be controlled within the deviation range of 2%, which means that the color difference of the plate on the same plate is well controlled. The color difference is basically controlled within a consistent range.

3. Surface condition:

Stainless steel plate manufacturers will go through a lot of circulation procedures in production, processing, hoisting and transportation. If you are not careful, there may be situations such as surface scratches. Therefore, the degree of surface protection of a plate is also a standard for evaluating the quality of a titanium plate. . In the selection of daily stainless steel sheets, consumers are unable to distinguish the slight color difference with the naked eye, and many unscrupulous merchants will exaggerate the purity of the color and the warranty period of the color. In fact, the weather resistance of a titanium plate is related to many aspects, such as electroplating method, plating time, post-plating treatment, use environment, follow-up maintenance, etc., which will affect the service cycle and weather resistance of a titanium plate.
