For a long time, Coating factories have relied on visual inspection in the work of color scheme, which is easily affected by the physiological and psychological factors of observers and natural rays of light. In order to improve the scientificity and accuracy of color scheme work, this paper introduces the application of CR-10 color difference meter in Coating color scheme, and proposes optimization measures for the problems existing in its actual operation. Coating color scheme is a key link in the production process of Coating, and its accuracy directly affects the mass and market competitiveness of products. The visual color scheme has shortcomings such as strong subjectivity and poor repeability, while the CR-10 color difference meter, as an accurate and objective Color detection tool, shows obvious advantages in the Coating color scheme.
CR-10 color difference meter working principle
The CR-10 color difference meter is based on the principle of three primary colors (red, green, and blue). Color analysis is divided into L, a *, and b data forms through electronic computer operation. Among them, L represents lightness, and a and b * represent different shading directions. By comparing Color data, the color difference value (Delta E) can be obtained to determine the proximity of the two Colors.
Application of CR-10 color difference meter in Coating color scheme
Quantitative Color: Through measurement, Color is expressed in data form, which is convenient for formulating the basic formula.
Color scheme adjustment: According to the color difference value (Delta E) and Color data, determine the adjustment direction and quickly find the appropriate color scheme.
Improve the accuracy of color scheme: CR-10 color difference meter can eliminate human factors interference, improve the accuracy of color scheme.
Existing problems and optimization measures
There are problems: high requirements for measuring samples, susceptible to acidity, and the bottom of the methanol tower is prone to corrosion.
Optimization measures:
(1) Control the water content of circulating methanol: Through experiments, it is determined that the water content of circulating methanol is controlled at about 0.02% (wt) to reduce acidity.
(2) Control the temperature of the reaction tower tray: Through industrial tests, the optimum operating temperature was determined to be 125 ℃ for the K layer, 115 ℃ for the L layer, 107 ℃ for the M layer, and 105 ℃ for the N layer to reduce acid formation.
Through the application of CR-10 color difference meter in the Coating color scheme, the scientificity and accuracy of the color scheme work are improved. Aiming at the existing problems, through theoretical analysis and industrial tests, optimization measures are found out, which provides an efficient and reliable color scheme method for the Coating industry. In actual operation, the water content of circulating methanol and the temperature of the reaction tower tray should be strictly controlled to ensure product mass and equipment Stability
