Progress in application of precision coating technology

Application progress of precision coating technology precision coating is an important processing technology to change and improve the surface characteristics of materials. with the continuous development of science and technology, precision coating has become an indispensable technical means for the research and development of many important functional materials. In particular, precision coating technology can meet the special requirements of some coatings, thereby increasing the added value of materials and expanding their application scope.

Characteristics and application of precision coater

With the development of modern electronic industry, precision coating has been gradually developed. After the fine painting technology in the United States, the development of Japan and Europe has been quite mature, while the technology in Taiwan is relatively insufficient. The obstacle to the localization of imported air flotation furnace lies in the high price. The material basis of precision coating process is precision coating equipment. The main characteristics of precision coating are: slot extrusion, precision leveling rod, air drying, coating damping magnetoresistive head, and gas-liquid buffer support.

Precision coating technology

Understand the precision coating process. The traditional precision coating methods, such as blade coating or roller precision coating, are simple and convenient to operate, but can only produce low value products at a unit price of less than 10 yuan per square meter. Moreover, this coating method belongs to an open operation mode, and solvent evaporation affects the health of operators. Environmental protection awareness is becoming increasingly important today, so it is necessary to make appropriate adjustments.

Technology of Precision Coating

Precision coating technology can be applied to IC, PCB, photoelectric, people's livelihood, medical and other industries. First of all, we must define why the coating technology is. The so-called broad coating, by definition, covers a wide range of coating. The coating technology developed by the Industrial Research Institute is roller coating technology. Precision coating: First, a roll of substrate (such as PP, PET, PI, copper foil, etc.) is coated on the substrate through the coating device, and then the solvent is removed through the drying process, rolled into a roll for finished or semi-finished products. A simple example is the production of adhesive tape. The production process is to cover the pressure-sensitive adhesive on OPP or PVC, dry and wind it in an oven, and then sell it after packaging. However, this coating process is relatively simple (we call it the traditional precision coating method).

Classification of precision coating methods

Traditional coating methods, such as comma coating or roller coating, are simple and easy to operate, but can only produce low value products with a unit price of less than 10 yuan/square meter. Moreover, this coating method belongs to the open operation mode, which will cause the problem of solvent volatilization and affect the health of operators. Nowadays, the awareness of environmental protection is becoming more and more important, and it is necessary to make appropriate adjustments.
