What is membrane filtration? It is a precision separation technology that can achieve molecular-level filtration, the main difficulty lies in the precise control of filtration accuracy. "You can think of it as a sieve. To filter out unnecessary impurities, basically every industry needs." Jia Jiandong, CTO of HZKB Filtration Technology Group, said, "For example, the most advanced chip in the field of semiconductor chip The width of the line is as thin as 7 nanometers and 5 nanometers, which means that smaller impurities must be filtered out, and the accuracy of the filter membrane must even reach 1 nanometer. "
The company's new products, sound-permeable membranes and breathable membranes, have become suppliers of Huawei's and other brands of mobile phone sound-permeable membranes, breathable membranes and Huawei's 5G base stations, achieving an increase of more than 50%.
If the mobile phone we use every day has waterproof function, we need to use waterproof breathable membrane and waterproof sound-permeable membrane to meet the requirements of both waterproof and dustproof, and breathable and sound-permeable. In the past, because the technical difficulty was too high, most of the similar membranes were imported from abroad. "It is difficult to meet the requirements of the membrane waterproof level, the energy loss of various audio transmission through the membrane is extremely small." Jia Jiandong introduced, "Each membrane order has tens of millions or even hundreds of millions of membranes. In order to achieve the same performance of each diaphragm and have R & D and manufacturing capabilities, only a few companies in the world can do it. We are one of them. "
At present, HZKB is the company with the largest production capacity in Asia in the field of filtration membranes, and the production capacity is the sum of the top ten domestic companies. The company has world-class microbiology laboratory, filtration performance laboratory, electron microscope room, integrity testing laboratory … In recent years, HZKB annual scientific research investment accounted for more than 10% of revenue, and more than 150 existing invention patents The microporous filtration business has gradually transitioned from daily necessities to biopharmaceutical filtration, semiconductor ultrapure filtration and other fields.
Opportunities are only for those who are prepared. In this sudden Coronavirus (COVID-19) pandemic, ECMO (artificial membrane lung) became the focus of attention. The disposable pulmonary membrane PMP, which is the core part of ECMO, is monopolized by foreign companies. HZKB took the lead in starting the R & D project of PMP oxygenated membrane filaments three years ago. It is the only domestic enterprise that develops such membrane filament materials. The PMP oxygenated membrane filaments produced by HZKB have completed the clinical trial stage, and the use effect has reached the international first-class level.
At present, HZKB is building the largest membrane filtration application research and verification experiment center in Asia, and is beginning to establish a biosafety laboratory to provide biopharmaceutical companies with complete solutions for biological testing and filtration. "Our total investment is over RMB 1 billion in the headquarters R & D building. We will accelerate the construction of new production lines for ECMO membrane materials, diagnostic reagent materials and hollow fiber materials." Zhang Yingmin introduced.
