Paint (as shown in Figure 1) is a thick liquid coated on the surface of a protected or decorated object and can be firmly attached to the coated material. Usually, it is mainly composed of resin, oil or emulsion, added or not added with pigments, fillers, additives and organic solvents or water. Due to raw materials and other reasons, it is easy to produce color difference in the production process of coatings. In order to strictly control the quality of coatings, more and more manufacturers decide to use precision measuring instruments to detect the color difference of coatings.

After learning that the CS-580 spectrophotometer (as shown in Figure 2) of Hangzhou CHNSpec technology can solve the problems of color difference measurement and quality inspection of coatings, a Chemical Co., Ltd. in Dongguan invited CHNSpec professionals to the manufacturer to directly demonstrate how to use CS-580 to measure the color of coatings. The company has a personalized management team, excellent engineering and technical team, professional color matching technicians and perfect after-sales service. It pays special attention to scientific and technological innovation and strengthening management, R & D and production of high-tech products, and wants and creates the needs of customers. In order to improve product quality and strictly control quality inspection, the company seeks to use CHNSpec spectrophotometer to detect color difference.

In order to facilitate the measurement, the manufacturer adopts the method of directly measuring the sprayed parts after coating.
The specific measurement process is as follows:
Step 1: prepare the sprayed part samples to be tested (as shown in Figure 3);

Figure 3 - painted parts to be tested

Step 2: turn on the instrument, set various parameters and formulas according to the instructions, and conduct black-and-white calibration;
Step 3: after the black-and-white calibration is completed, press the "print" key, first locate the measurement area with the image, align the standard sample to be measured with the test hole, be careful not to leak light, so as not to affect the test results, and then press the "test" key to complete the measurement and view the test results;
Step 4: after the above standard sample is measured and saved, press the "menu" key to enter the "sample measurement" interface under the standard sample. Align the sample with the test hole according to the standard sample measurement method, press the "test" key for measurement, and complete the color difference measurement after "dripping" sound, and then the measurement result can be obtained (as shown in Figure 4).

After the measurement is completed, through the above simple operation, the spectrophotometer CS-580 of CHNSpec technology can intuitively show the lab value of the measured samples and the color difference between different samples. The customer is very satisfied with the test results and bought the instrument on the spot. The company introduces international high-end technology and adopts advanced production equipment and high-quality raw materials such as Japan, South Korea, the United States and Germany, Committed to the R & D and production of high-end coatings. The CS-580, which uses CHNSpec technology this time, will certainly be able to unite strong and strong, so as to improve the product quality of the company and create better benefits.
