The importance of color performance color performance on plastic colored plastic colorant basic performance, color performance is pointing to color strength, hue and hiding power, which is the first feature evaluate coloring properties. Tinting strength is a measure of the colorant imparting depth coloring plastics, tinting strength can be quantified as an absolute value, but also with other colorants relative values ??compared. Tone refers to the basic color pigment. On the colorimetry can colorant hue fertilizer products, lightness and saturation to represent. Color performance is an important performance indicator colorant in the colorant excellent quality fertilizer coloring plastics, which determines the stability of the plastic color quality fertilizer company colorants, coloring costs and coloring process. How to properly use plastics coloring coloring indicators (1) of the same color is applied to different plastics coloring, the color performance, color strength and other indicators are not the same, strictly speaking mentioned color pigment in plastics coloring performance must mention its application solution quality. (2) In the colorimetry standard depth, the depth of color through the sample prepared under standard conditions to determine the absolute depth of the pigment colorant fertilizers, in order to achieve a certain amount of color depth necessary to represent. Its representation as a standard depth, 1/3 standard depth, 1/25 standard depth. This representation can be designed by Schmelzer continuous shade depth map to visually represent it. Fertilizer colorant is guaranteed, fertilizer colorants, Weifang Weifang Fuyuan Fuyuan provided by the Environmental Protection Technology Co., Ltd.
