How to choose and apply Foshan powder colorimeter? 13889943666

As the largest color difference meter manufacturer and sales office in Foshan, Foshan Precision Measurement Instrument has been investigating and understanding the powder coating industry for many years. It is not difficult to find the importance of the color difference meter in the powder coating industry. Powder coating can be described as a true application in various industries. In all industries, its color is good or bad, and the degree of color difference directly affects its quality and quality. The application of Foshan Precision Color Difference Meter is like a ruler in the powder industry, which regulates the color difference range of powder coatings.

In the early days of powder coating development, it was mainly used for metal corrosion protection. With the continuous development of powder coating production and application technology, the strengthening of environmental awareness and regulations in various countries around the world, the scope of application of powder coatings has continued to expand, and the decorative and landscaping effect of powder coatings has also been increasingly People pay attention to it, and the assembly line processing and assembly of modern enterprises (such as refrigerators, air conditioners, instrumentation, metal doors and windows, aluminum profiles, electromechanical equipment and other manufacturers) also require a high degree of stability in the quality of the coating product inside and outside, and the coating color uniformity between batches. Important customer requirements.

The color matching of conventional powder coatings belongs to the complex subtractive mixing in the color mixing law. Kubellka-Munk theory believes that light is completely diffused in the colored layer. The "two-constant Kubellka-Munk theory" uses the K / S spectrum of the coating. (K-absorption, S-scatter) to characterize the pigment, and finally use a spectral matching algorithm to achieve constant matching. The color matching instrument uses this principle, uses color matching software, selects pigments from the pigment library for K / S spectrum compounding calculation, and finally provides the formulator with the ideal color difference prediction for color matching personnel to choose. At the same time, the color difference meter is used for color monitoring, and the color difference is found in time to control the color difference within a certain range. The iwave color difference meter simulates the human eye's photosensitive mode to identify the color. At the same time, the color is digitized to make the abstract color concrete. It is easier for operators to process and analyze.

The color matching software and the color matching software of the color difference meter all introduce the database building method in detail, mainly the data of blackboard, white board, hiding power and pigment. In addition to the pigments for which data is to be established in the formula, other raw materials should be selected from the best quality varieties or the most commonly used varieties of the enterprise and kept fixed to ensure reliable data and facilitate future color deployment. Avoid poor quality (such as color miscellaneous, non- Stable), infrequently used varieties. Name a database and match the selection of pigments, the general amount is 20 to 25 kinds (such as 4 kinds of red, 2 kinds of blue, 2 kinds of green, 2 kinds of orange, 2 kinds of orange red, 2 kinds of purple, 3 kinds of black, 2 kinds of white, The other three types), move its data into, that is to complete the establishment of a single database, as long as the name of the database is specified during color matching, the system randomly selects the pigments in the database for matching. The establishment of an accurate database of information can effectively guide the color matching work for a long time, which is beneficial to the color matching personnel's rapid realization of expectations. However, affected by objective factors such as equipment aging, customer pigment quality fluctuations, and raw material adjustments, the deviation between the sample and the computer's predicted results will continue to increase. With the continuous introduction of new pigments, the database of pigment supplements, Updates and corrections are also ongoing. Because many external environmental disturbances may change the color from time to time, a color difference meter and a color matching system are used to monitor and record the changes in color at the same time, and fill the database to complete the color data in time.

The combination of color difference meter and color matching system is currently the most perfect color management method for powder coating manufacturers. The combination of color difference meter and color matching system is used to minimize the color difference of powder coating and make the color of powder coating more perfect.
