Polyimide film is the world`s best-performing film insulating material. It is called "gold film" in the scientific and technological circles. It is widely used in the manufacture of mobile phones, computers and other electronic products, as well as in satellites, airplanes, and high-speed railways. Manufacture of important components in related fields.
Previously, this kind of film products have been monopolized by DuPont and other companies in the United States. Since the beginning of January this year, China's SDZC Advanced Materials Technology Group "2000 tons of polyimide film project" has been commercialized. "Our first phase product is thermal imidized polyimide film. Now there are three production lines, all of which are ready for commercial production." Student Sun, CTO of SDZC, told Hay Think.
When it comes to corona-resistant polyimide film, DuPont of the United States has always occupied most of the market share. SDZC has invested tens of millions in three years to achieve mass production of this product, not only breaking the United States DuPont’s monopoly has also reduced costs, and the products produced are used in many fields and have won praise from many manufacturers.
In the film insulation material production industry, SDZC has the most complete product technology and the most advanced technology. The products it produces have a very good market, and the supply of products exceeds demand. "We are now using the thermal imidization production process, and we are also preparing to introduce two most advanced chemical imidization polyimide film production lines from Japan. After these two production lines are put into production, we will become China's DuPont "Student Sun said.
In 2020, SDZC was rated as a city-level superior industry plus artificial intelligence benchmarking enterprise, built a digital workshop, and gradually became a smart factory. Today, SDZC has realized intelligent manufacturing on the production line. "Take the glue making process in the production process, the previous production relied on manual feeding and manual adjustment of adhesion, and the later transportation also relied on manual labor. Now it is fully automated. And intelligent, the automatic feeding and tack-adjusting device we manufactured achieves the four characteristics of reducing labor, saving materials, improving quality, and stabilizing the process." Student Sun said that on SDZC's intelligent production line, all process parameters are collected in real time. , And feedback to the smart terminal, you can intuitively see the energy consumption, output, product quality and required process parameters of the entire production line. Not only that, the medium-wave heating method pioneered in the production process has the characteristics of faster heating, more accurate temperature and more energy-saving under the same conditions. In the tightening process, the splint-type tightening process device manufactured by it greatly improves the stability of the film and ensures the uniform thickness of the film.
At present, the corona-resistant film produced by SDZC has been used in batches of offshore wind power motors, oilfield drilling motors, coal mine motors, submersible motors and other fields. For the future of the new material industry, SDZC products have been applied to China's high-speed railway "Fuxing" Corona-resistant film, 5G communication flexible circuit board materials, high-end heat dissipation carbonized materials, copper-based new materials, etc.
