The Ministry of Industry and Information Technology will issue "Guidelines for the development of high performance film industry"
Song Xianzhu, deputy director of the Ministry of Industry and Information Technology's Department of Raw Materials Industry, said that in recent years, China's film industry has developed rapidly, but there are problems such as weak innovation capacity, fewer product types, small business scale, and high-end membrane materials relying on imports. For example, in the field of water treatment, there are not less than 500 enterprises engaged in microfiltration ultrafiltration, but less than 10 million yuan in output value of more than 500 million yuan, and related technical standards are even less. The Ministry of Industry and Information Technology, the Ministry of Finance, and the National Development and Reform Commission will provide support to the development of membrane technology in terms of policies and funding. He proposed that one of the key issues that restrict the development of the film industry is the supply of raw materials. Polyvinyl chloride, polypropylene, etc. can basically be based in China, and high performance materials such as polyvinylidene fluoride are heavily dependent on imports. Membrane material preparation needs to be tackled in terms of raw material handling, impurity removal, on-line product inspection, thin film material, and composites. Prof. Zhu Baoku from Zhejiang University and Wu Chen, general manager of Shandong Lanjing Membrane Technology Engineering Co., Ltd. proposed that to solve the problem of missing raw materials, polysulfone, polyethersulfone, polyimide, polyvinylidene fluoride, polyvinyl chloride, etc. Common materials are used to distinguish between common materials and characteristic materials, and they are organized to address industry needs. Song Xianzhu pointed out that the next step in the film industry is to focus on the use of membranes for water treatment, caustic soda, power batteries, and optical polyester. In China, 90% of reverse osmosis membranes for seawater desalination rely on imports. Domestic membranes need to be improved in terms of membrane module stability, service life, and water utilization efficiency. The annual production capacity of caustic soda in China is 34 million tons, and the ion-exchange membrane method accounts for 86%. However, the membrane used is almost entirely dependent on imports. At present, the Dongyue Group's perfluorinated ion membrane has achieved breakthroughs, and it is necessary to improve quality and enhance application and promotion. Power lithium-ion battery diaphragm is still in a breakthrough. Driven by flat-panel displays and point-and-touch technology, optical polyester films have developed rapidly. In the future, the development of additives and coating equipment should be strengthened. Jiang Jian, Director of the Petrochemicals Division of the Raw Materials Division of the Ministry of Industry and Information Technology, said that on the basis of fully understanding the status quo of the industry, the Ministry of Industry and Information Technology will issue “Guidelines for the Development of High-Performance Membrane Industry†to clarify key technological research and development and industrialization directions, and focus on solving weak industrial innovation capabilities.
