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).

Domestic precision coating plants and other industries use traditional methods for processing, because these methods are simple in construction and easy to operate, but they can only produce low value products with a unit price of less than 10 yuan/square meter. Moreover, this coating mode belongs to an open operation mode, and solvent volatilization affects the health of operators. Especially today's environmental awareness is becoming more and more important, so it is necessary to make appropriate adjustments.
Foreign advanced factories carry out relevant businesses with extrusion coatings. The price of products derived from this technology is at least more than 50 yuan/square meter, and some can even reach more than 3000 yuan/square meter, which is very different from traditional products. We must pay attention to this.
The substrate of precision coating products is developed by coating technology, which covers many technologies. As a key technology, its importance is as follows: quality, formula 25%; Coating 35%; Knowledge 25%; Equipment 15%.
Although the material formula is an important source (25%), the proportion of processing and other processes that must be handled is as high as 75%. Fang said that the importance of the process is not greater than that of the synthetic formula. In fact, all product development of the formula or source is led by it. Take the material development system as an example, the material synthesis development system is indivisible, and the relationship between the two is very close and indivisible.
The establishment of the technology platform of precision coating technology, together with various domestically developed high-performance coatings, can be used for various product development and can be used in a wide range of applications. The introduction is as follows: Because precision coating technology covers a wide range, there is no real forecast trend of coating output value published at present, but from the above table of product associations and technology associations, if every individual is a growth trend, Then the overall output value will be amazing.
