Development status of flat panel solar coating equipment technology

With the vacuum era entering me, it has been continuously developed, technology has been continuously updated, and solar vacuum has been rapidly developed. With the rapid development of flat panel solar collector production and marketization, as the core technology of flat panel collector - heat absorption board Coating equipment and technology have also developed rapidly. However, due to the technical and cost problems at that time, it has not been widely promoted in China. But to have a certain market, it will take a long time to develop and run.

      In the vacuum coating industry abroad, the internationally developed countries, especially in Europe, the production of selective absorbing coatings has two main characteristics: one is vacuum coating technology; the other is winding continuous coating The market for vacuum coating equipment, the technology has matured, is the main development direction of coatings, Germany's titanium oxide film formation process represents the current highest level of technology in this field. In order to break through the foreign technology leadership in vacuum coating equipment, in recent years many well-known domestic manufacturing companies have begun to develop and promote a variety of new products, and achieved good results. A very small number of companies have begun to master the core technology - blue titanium coating technology, which can achieve strip-type, whole-plate or coiled production, breaking the monopoly of foreign flat-panel solar core technology. Although the domestic weather resistance and appearance have been significantly improved, there is still a gap compared with foreign countries.

The introduction of foreign advanced ITO coating technology, through the digestion and absorption of advanced vacuum coating technology, independent research and development and innovation, the development of high-performance full-board winding blue film production line, mastered the core technology of blue film production.

In the next few years, the technology of vacuum coating will gradually move toward solar coating technology, because people's requirements for machinery and equipment are higher. High-tech precision instruments require better coating equipment, which is why many coating equipment companies will The direction and trend of walking.
