How to apply colouring force correctly with plastic stain2017.11.20 10:16
How does plastic coloring apply the index of coloring force correctly? Here are three of the most used methods.
The first, the same pigment used in different plastic colorants, its color properties and its shading force and other indicators are not Similarly, it is necessary to mention the application of the pigment in the color properties of plastic.
Second, standard depth is in chromaticity, which can be used to judge the absolute depth of pigment by the color depth of samples prepared under standard conditions The amount necessary to achieve a certain color depth. The method is standard depth, 1/3 standard depth, 1/25 standard depth Degrees. This method can be directly represented by the color optical continuous depth graph designed by Schmelzer.
The third, the maximum absorption wavelength of the colorant determines its color, and the absorptive capacity at the maximum absorption wavelength determines it Color. But the coloring force is not only related to its chemical structure, but also to the dispersibility of pigment. The better the pigment is, the better it is The higher the color force. Pigment coloring and color matching are of great significance. For example, if you want to make a dark tone, you should choose the color. When it is necessary to make a light color tone, choose a low color variety (inorganic pigment). It's more expensive to get a paint job when you're coloring it , can choose the other color to replace with color, but two kinds of pigment shading force is different in substituting for the same color requirement also different.
