With the development and breakthrough of new technologies in China, the needle filter will also be upgraded and upgraded to meet more application needs. However, there are certain problems behind the rapid development. At present, most of the needle filter manufacturers in China are small and medium-sized enterprises, and their innovation ability is limited. Therefore, the needle filter is still mainly imported, and the market profit attracts. Many well-known foreign companies have entered the Chinese market and competed with domestic needle filter manufacturers, which inevitably intensified the competition in the needle filter industry. It has also enabled more companies to achieve rapid competition through continuous innovation and product quality supervision. A foothold in the field has accelerated the development of the domestic needle filter industry. Together with the government's support for instrument production and high-tech industries, the overall level of the needle filter industry in China will increase significantly in the next few years.
The main indicator of the needle filter is its filter pore size, sealing and small resistance design. With scientific and reasonable filtration waterway design, choose filter membrane and support, and chemically stable shell material. The material of the filter membrane needs to adapt to the different chemical properties of the filter media. Currently used are vinylidene fluoride film, nylon film, and mixed fiber resin film. The filter membrane has a diameter of 13mm, 25mm, and 50mm. It is widely used in various fields such as medical and health, biochemistry, and the like.
