Embodiment 1

[0047] It is necessary to color a row of aluminum profiles with a surface area of ​​100 square meters. The target color of coloring is champagne 3# color, the empirical fading constant k is 0.12, and the negative current per unit area is Q 单位负通 Take 730 coulombs, the positive current flow per unit area Q 单位正通 Take 330 coulombs, coloring area S 总 It is 100 square meters, and its theoretical effective total electricity is calculated as: Q 理论有效 =730×100-330×100×0.12=69040; during the coloring process, real-time calculation of the actual effective total power Q 实际有效 , the actual effective total power Q 实际有效 =∑(actual negative current I 负通 ×Negative on-time T 负通 )-∑(actual forward current I 正通 × positive time T 正通 )×0.12; and judge the actual effective total electric quantity Q 实际有效 Is it greater than or equal to the theoretical effective total electric quantity Q 理论有效 , after judging the actual effective total electric quantity Q 实际有效 Greater than or equal to the theoreti...

Embodiment 2

[0049] It is necessary to color a row of aluminum profiles with a surface area of ​​90 square meters. The target color of the coloring is bronze color. The value of the empirical fading constant k is 0.31, and the negative current per unit area is Q 单位负通 Take 2500 coulombs, the amount of positive current Q per unit area 单位正通 Take 900 coulombs, coloring area S 总 It is 90 square meters, and its theoretical effective total electricity is calculated as Q 理论有效 =2500×90-900×90×0.31=199890; during the coloring process, real-time calculation of the actual effective total power Q 实际有效 , the actual effective total power Q 实际有效 =∑(actual negative current I 负通 ×Negative on-time T 负通 )-∑(actual forward current I 正通 × positive time T 正通 )×0.31; and judge the actual effective total electric quantity Q 实际有效 Is it greater than or equal to the theoretical effective total electric quantity Q 理论有效 . When the coloring waveform has been powered on according to the original theoretical valu...

Abstract

The invention provides a coloring control method and system. The coloring control method comprises the following steps: (1) calculating theoretically effective total electric quantity Q theoretical effectiveness; (2) calculating actually effective total electric quantity Q actual effectiveness; (3) judging whether the actually effective total electric quantity Q actual effectiveness is greater than or equal to the theoretically effective total electric quantity Q theoretical effectiveness or not; if so, stopping electrifying; otherwise, continuing to electrify. The coloring control method and system provided by the invention can be used for accurately controlling a coloring process of an aluminum sectional material and the success rate of one-step coloring is effectively improved; a test shows that the success rate of the one-step coloring of the aluminum sectional material can be improved to be more than 75% through the coloring control method and system provided by the invention.

Description

technical field [0001] The invention relates to the technical field of aluminum profile coloring, in particular to the technical field of aluminum profile electrolytic coloring. Background technique [0002] Aluminum profiles are widely used in many technical fields such as architectural decoration, transportation, electrical instruments, etc. With the expansion of the application range, the requirements for the decorative performance of aluminum profiles are also getting higher and higher, so it is necessary to carry out various coloring treatments on aluminum profiles . [0003] At present, the electrolytic coloring method is the most commonly used technical method for aluminum profile coloring. However, with the existing technical means, it is impossible to judge the color depth of the aluminum profile before the end of power-on, and it is even more unpredictable whether it is necessary to repair the fading; and in actual production, the success rate of one-time coloring...
