Many color stainless steel plate manufacturers in order to reduce the cost, in the production process to speed up, in order to achieve higher output;So the film then gets thinner, and the working time is reduced from the usual one hour to 10 minutes or less.At the same time, also because working time is too short, voltage, current, gas uniformity and so on the technical requirements and phase should be lower and unstable, which easily produce color film layer and the combination of the stainless steel surface force, as well as the color is not uniform, eventually lead to easy to produce off color, even more serious membrane layer falls off like now.
At the same time, the traditional water plated stainless steel black titanium plate also has a lack of current, voltage and short working time.Stainless steel color plate surface color film too thin, will also bring up the product type into or after use, to the temperature, humidity, even by touch as a chemical raw materials and produce learn under reaction, and can cause local, not rules are set to produce the color deterioration, and produce this kind of color distortion phenomenon, there is no method to predict the degree and time.
However, not all color difference is human, non-human case of stainless steel plate color difference is caused by the following conditions:
First, the working gas is not evenly distributed in the furnace body, resulting in uneven gas ionization, color difference;
Second, the arc source is not evenly distributed, resulting in less than the sputtering, plating to the color difference;
Three is beyond the splash range, color difference;Four is no fingerprint will produce color difference;
In addition to the above several conditions, color difference is also related to temperature, furnace condition, shift shift, batch, etc. There will be a little bit of color difference, but it is not visible to the naked eye.
Which colored stainless steel plates are not acceptable?
First, with a plate on the color difference, said board board board department did not have enough to reflect, is a thin coating of the body.Secondly, the surface of the titanium plate with small particles or small air bubbles can not be, dust particles in the titanium layer under the effect of solid color, said the factory did not have the stainless steel surface cleaning.
Again, the same batch of stainless steel plate color difference can not be obvious, affect the beauty of decoration.Finally, the price is too low stainless steel plate can not be bought, stainless steel plate should be within the reasonable price, stainless steel hardness is high, once made of product quality problems will cause difficult to repair the loss.
