According to the Xinhua News Agency, Helsinki, May 23, a Finnish company has recently developed a Sawer Solar company in Finland that can use three layers of nano-coatings to efficiently absorb solar energy.
This new type of solar panel has two major technological innovations. One is to use three layers of nano-coatings with a total thickness of 100 nanometers to reduce the energy loss caused by the reflection of sunlight; the other is to use a "DC technology" to allow The water circulates directly inside the heat-absorbing plate rather than the pipe connected to the heat-absorbing plate, thereby increasing the energy conversion efficiency.
Savo Solar said that in the performance test, this new type of solar panel can work at a high temperature of 300 degrees Celsius, while the current solar energy products generally only require resistance to high temperatures of 220 degrees Celsius.
The communique said that the next R&D goal of the company is to raise the normal working temperature of the above new products to 550 degrees Celsius.
Rolling mill oil film bearing technology, is a system engineering technology, at the same time, is also a multidisciplinary field of comprehensive engineering technology, its development speed and the formation of supporting capacity, from one side reflects the development speed of China's industry and the level reached. This paper briefly discusses several main aspects such as operation technology, manufacturing technology, testing technology, theoretical research, product development, and complete set of capabilities
1. Operation technology, including a complete set of knowledge and skills such as storage, cleaning, installation, commissioning, operation, maintenance, diagnosis, and management of rolling mill oil film bearing parts. The correct application of running technology is a reliable guarantee for the safe operation of bearings.
In the early 50s, only the reversible rolling mill of Anshan Iron and Steel Cold Rolling Mill in China was equipped with oil film bearings. Its operation and management are carried out in full accordance with the relevant regulations of the Soviet Union. In the traditional process, the rolling pressure is not large, the rolling speed is low, the lubrication system is also very simple, and the operating technology level is relatively low. However, in actual operation, the work of the relevant management, technical personnel and operators is very serious, strictly in accordance with the regulations, and has accumulated experience in use and maintenance.
