Recently, experts from the Ministry of Science and Technology of the Ministry of Science and Technology organized an acceptance of the “12th Five-Year” National Science and Technology Support Program “New High-safety Diaphragm Research and Application Demonstration for Lithium Ion Power Batteries” in Beijing. The acceptance expert group listened to the report of the project leader on the implementation of the project in accordance with the “Regulations on the Management of the National Science and Technology Support Plan” and the “Special Funds Management Measures of the National Science and Technology Support Program”, and reviewed relevant materials. After questioning and discussion, acceptance The expert group believes that the project has completed the main tasks and indicators specified and agreed to pass the acceptance.

The project uses a controlled UV cross-linked poly(aryl ether ketone) to prepare a lithium battery separator with adjustable thickness of 20-40 microns. The key technology of lithium ion power battery based on new high safety diaphragm is studied, and the battery system test and development platform is established. , carried out research on efficient energy balance technology of battery management system. Established a production line of 30 tons of controlled UV cross-linked polyaryletherketone lithium ion power battery separator, with an annual output of 1 million square meters of controlled UV cross-linked poly(aryl ether ketone) lithium ion power battery separator production line, battery system in electric Demonstration application on the bus. The acceptance expert group unanimously agreed that the project passed the acceptance.

Steel Casting

In the investment casting industry, steel castings are the most used castings in the manufacturing industry, and are widely used in equipment, agricultural machinery, machining, and automobile industries. Metal castings can produce parts with complex shapes, but there are also requirements for the design of the product structure. In the case of meeting the requirements of use, it should also try to comply with the casting process. For example, in the structural design, care should be taken not to have thin walls, which may easily lead to dissatisfaction with pouring or product deformation; for example, try not to have sharp corners, try to use radian transitions; and try not to appear small and deep blind holes, It will cause great trouble for foundry sand cleaning. Of course, there are many other structural problems. We will improve and optimize the product structure according to the customer's drawings without changing the customer's functional use, so as to maximize the product qualification rate and production efficiency. In some cases where the structure cannot be changed, we will also perform some follow-up processing after casting according to actual problems, so that the expected results can also be achieved.
