Information

Sometimes we have a requirement for the appearance and color of enamel products, especially some uncommon colors that need to be customized, how to judge whether the color of enamel products meets the requirements, first pay attention to the choice of enamel pigments, except for the most common cobalt blue, Cadmium yellow, cadmium red, cadmium green, copper red, there are other transitions such as orange, orange, lemon yellow, milk yellow, green or coffee, antimonymes, etc., if there is a special color Requirements, enamel manufacturers can inform enamel pigment manufacturers to do their own demand, and then prepare for enamel products after the sample reaches the requirements.

When the color difference of the enamel product is detected, the following two methods are usually used:

Method 1: Test method

The human naked eye is relatively sharp to color, and the test personnel of the visual method need to master certain chromaticity knowledge. It is necessary to strictly abide by the conditions for test equipment, light source conditions, observing environments. It is designed to compare test products and samples under equal conditions. Let the result more accurate. Under normal circumstances, it can be more accurately seen with the color difference, but if it is more accurate data, such as saturation, tone and minor differences, it is difficult to describe and do not use specific values ​​to describe and record.

Method 2: Instrument method

The enamel industry is generally used to detect the chromatic aberration between the test item and the sample. First, the base color is first measured, and then calculate the difference between the object to the sample and the sample, determines whether or not the chromaticity requirements are reached according to the difference. The color meter is cheap, the value is objective, but its measurement accuracy is usually lower than the judgment of the human eye, so the enamel manufacturer can combine the chromatin analytical means, which requires the total color difference, and then use the visual measure to evaluate Judging the color, makes the result more accurate.
