Anti-smog screens, black technology to filter PM2.6
There is a saying that goes like this: There is no lack of beauty in this world, but the eyes that discover beauty are lacking. But now, this sentence has been ridiculed as 'I had a pair of eyes that found beauty, but I lost it to the smog.' Junada Technology is a foreign member of the Royal Academy of Engineering, a member of the Singapore Academy of Engineering, a member of the Indian National Academy of Engineering, and a member of the ASEAN Academy of Engineering and Technology. It is understood that Academician Syram has long been engaged in research on the processing and surface functionalization of polymer composites, biocomposites, and electrospinning nanofibers, mainly to provide technical support for the research and development and industrialization of the project, and to solve technical difficulties. Breathable and impermeable, energy saving by one third: In the exhibition hall of Junada Technology, an anti-smog screen window has successfully attracted the attention of visitors. The reporter saw that this anti-smog screen is not much different from ordinary screens in terms of appearance; in terms of color, the appearance of the anti-smog screens is light gray, slightly brighter and whitish; With a touch of the hand, it is obvious that the anti-smog screens are stronger and smoother, and the 'eyes' are small. The staff performed a performance demonstration on the spot, and poured a bottle of water on the screen window. After a few minutes, no drop of water penetrated the screen. 'The electrospinning nanofiber material is a fiber material with a diameter in the range of tens to hundreds of nanometers. This screen window is covered with a layer of porosity of 80% on the surface of ordinary screen window, and millions of micropores are densely packed per square centimeter. The nanofiber membrane has a pore size distribution between 100 nanometers and 300 nanometers. Taking into account the production cost and actual use effect, the filtration efficiency of PM2.5 (particulates with a diameter of 2.5 microns or less) is controlled at about 95%, which can effectively block fog Haze and dust enter the room without affecting the normal circulation of air, and have auxiliary functions such as sterilization, disinfection and radiation protection.' said Dr. Yu Miao, chairman of Junada Technology. According to reports, electrospinning nanofiber materials is the use of electrospinning technology to nanofiber fibers, which are currently used in screens, masks and filter cartridges. Yu Miao introduced that from the perspective of filtering dust, electrospun nanofiber materials can achieve a filtering effect of more than 99% for PM0.3 (solid particles or droplets with a diameter less than or equal to 0.3 microns), and achieve traditional filtering. Pressure drop below half. In the case of masks, when the pressure drop is reduced, the resistance will be reduced, and the ventilation effect will be good, and the smoothness of human breathing will be improved. Take the filter cartridge in the industrial field, the greater the resistance, the more powerful the fan must be drawn. The more energy is consumed, and the pressure drop and resistance come down, the energy is saved. The use of nanofiber materials can save one-third of the energy. From the laboratory to the industrialization: Internationally, professional electrospinning nanofiber production equipment and solution suppliers have appeared around 2010. For China, low output and poor quality controllability have always been the primary problems for nanofibers to move from the laboratory to the industrialization. 'We plan to start with the production of electrospinning nanofiber equipment, and then produce nanofiber products, along with China's'One Belt One Road' initiative, and expand the international market.' Academician Syram introduced that the project is positioned as the number one electrospinning in China A supplier of overall industrial solutions for new nanofiber materials, as well as the industrial development of new nanofiber materials in the fields of energy, electronics, biomedicine, chemicals and the environment, and functional textiles. To this end, on the basis of research results related to nanofibers at home and abroad, Gonada Technology starts with the most critical functional indicators such as the strength of nanofibers to bring the technology to the market. It is worth mentioning that Junada Technology also has the only domestic electrospinning nanofiber mass production line for mass production of nanofiber films in factories and workshops. 'The company itself is positioned as a technology exporter, and the output is equipment, raw materials and production technology.' Yu Miao introduced that the first step of the project is mainly for the development of screens, masks and other civilian products; the second step is for industrial water filtration and seawater. The development of desalination and air filtration filters, filter elements, and filter cartridges, the third step is the research and development of medical equipment. Electrospinning nanofiber technology can also help upgrade backward production capacity. 'As far as ordinary gauze is concerned, the price of a square meter is only a few yuan, the profit is very low, and it consumes a lot of labor and energy. Our medical anti-haze gauze is generally sold at 200 yuan to 400 yuan in the market. Yuan per square meter, the highest sold for 800 yuan to 1,000 yuan, which gives new vitality to the traditional industry.' Zhu Qinwen, deputy general manager of the company introduced. At present, the company's first-phase product anti-smog screens have been promoted in cooperation with larger screen manufacturers in China. The initial plan is to promote this technology in Hebei. The product has been mass-produced in November this year, and the order exceeds 20,000 square meters. . In addition, with the addition of anti-smog masks and electrospinning nanofiber products such as electrospinning guns, the sales revenue of this project will exceed 5 million yuan this year, and it is expected that the cumulative sales in the next three years will exceed 100 million yuan.
Cut resistance is one of the most critical performance indicators in personal protective equipment (PPE) testing, directly affecting worker safety in high-risk industries such as metal processing, machinery manufacturing, and emergency rescue. The TDM Cut Test Machine GT-KC28 plays a vital role in accurately evaluating the cut resistance of PPE products, including gloves, protective clothing, footwear materials, composite materials, rubber, and industrial textiles.
By adopting high-precision force control systems, intelligent data processing, and stable transmission technology, the GT-KC28 TDM Cut Tester can accurately measure the critical cutting force of materials and ensure excellent repeatability and comparability of test results. Its user-friendly touch-screen operation, comprehensive data storage, USB data export, and built-in thermal printer greatly improve laboratory efficiency and data traceability.
The TDM Cut Test Machine GT-KC28 fully complies with major international and national standards such as ISO 13997, EN 388, ASTM F2992/F2992M, ANSI/ISEA 105, and GB 24541-2022, making it a reliable solution for PPE manufacturers, third-party testing laboratories, and research institutions. Through precise and standardized cut resistance testing, the GT-KC28 helps reduce industrial cutting injuries, supports PPE certification across global markets, and ensures that protective equipment delivers reliable safety performance in real-world applications.
