In China, paint is traditionally called paint. The national standard (gb5206.1) defines coating as the general name of a class of liquid or solid materials that can form a solid coating with protection, decoration or special properties (such as insulation, anti-corrosion, marking, etc.) on the surface of objects. Coatings are generally made of film-forming materials, Pigments / fillers, dispersion media and additives through certain processes. Coatings are widely used. Because they can enhance the appearance decoration of metal structures, equipment, bridges, buildings, vehicles and other products, prolong the service life, have use safety or other special functions, and are important engineering materials supporting the national economy. It is mainly used in automotive coatings, architectural decoration, engineering machinery, ship anti-corrosion, containers, vehicles, etc.

Coatings can be divided into two types: architectural coatings and engineering coatings. In industrial production, the color of coatings is a major feature. The application of coatings of different colors in different environments has different functions. Therefore, controlling the color difference of paint color is a key problem.

1、 Automobile is an indispensable means of transportation in people's life. The paint (coating) on the surface of automobile is a variety of colors. For a car with bright colors, it is particularly important to ensure the unity of its surface paint (coating). Cs-390 and cs-392 of CHNSpec technology can solve this problem well.

2、 On some bridges, stadiums, wind power generation and other equipment, we can see that there is a layer of paint on the surface. Its function is to protect the appearance, prevent corrosion, and ensure beauty at the same time. For the color measurement of this kind of object surface, the portable spectrophotometer cs-520 series of CHNSpec technology can be easily competent.

3、 In the early stage of development, powder coating was mainly used for metal corrosion protection. With the continuous progress of powder coating production and application technology and the strengthening of environmental protection awareness and regulations all over the world, the application scope of powder coating has been expanding, and the decorative and beautifying effect of powder coating has attracted more and more attention, The assembly line processing and assembly of modern enterprises (such as refrigerators, air conditioners, instruments and meters, metal doors and windows, aluminum profiles, electromechanical equipment and other manufacturers) requires a high degree of stability in the internal and external quality of coating products. The consistency of coating color between batches has become an important requirement of customers. The high stability desktop spectrophotometer cs-821n of CHNSpec technology can well solve this problem.

4、 The color matching of coatings is still a difficult problem encountered by many customers. Whether the color provided by customers can match this color efficiently and accurately is a great test of the experience and ability of color matching masters. However, if it is matched with the spectrophotometer and CHNSpec color matching software, it can not only improve the work efficiency and make the formula more accurate, but also make the novice become a master in seconds.5、 In the paint industry, some colors are very complex, such as rock color paint. It has many different colors and full beauty. Ordinary color measuring instruments are difficult to measure the color data of rock color paint. CHNSpec technology's image spectrophotometer cs-828 is a professional instrument for measuring complex image colors. Minimum measurement 0.09mm ² Area, square inch, every minute.

In the actual production and use of the coating industry, a good color difference instrument can save the production cost and improve the work efficiency. CHNSpec technology has rich experience in color detection in the coating industry. CHNSpec technology connects colors with numbers.
