Anti-smog screens, black technology for filtering PM2.5
There is a saying that goes like this: There is no shortage of beauty in this world, but there is a shortage of eyes to discover beauty. And now, this sentence has been ridiculed as“Originally had a pair of eyes that found beauty, but lost to the haze”. Junada Technology is a foreign academician of the British Royal Academy of Engineering, an academician of the Singapore Academy of Engineering, an academician of the Indian National Academy of Engineering and an academician of the ASEAN Academy of Engineering and Technology. It is understood that Academician Xiram has long been engaged in research on the processing and surface functionalization of polymer composites, biocomposites, and electrospinning nanofibers, mainly providing technical support for the research and development and industrialization of this project and solving technical difficulties. Breathable and impermeable, one-third energy saving: In the exhibition hall of Junada Technology, an anti-smog screen window successfully attracted the attention of visitors. The reporter saw that this anti-fog screen window is not much different from the ordinary screen window in terms of appearance; in terms of color, the appearance of the anti-fog screen window is light gray, slightly shiny and white; When you touch it with your hand, you can obviously feel that the anti-fog screen is stronger and smoother, and“Eye”very small. The staff performed a performance demonstration on the spot, poured a bottle of water on the screen window, and after a few minutes, no drop of water penetrated through the screen.“Electrospinning nanofiber materials are fibrous materials with diameters ranging from tens to hundreds of nanometers. This screen window is covered with a layer of porosity of 80% on the surface of ordinary screen windows, and every square centimeter is densely covered with millions of micropores. Nanofiber membranes with a pore size distribution between 100 nm and 300 nm. Taking into account the production cost and the actual use effect, the filtration efficiency of PM2.5 (particles with a diameter of 2.5 microns or less) is controlled at about 95%, which can effectively prevent haze and dust from entering the room without affecting the normal air circulation, and has the ability to sterilize , disinfection and radiation protection and other auxiliary functions.”Introduced by Dr. Yu Miao, Chairman of Junada Technology. According to reports, electrospinning nanofiber materials are nanofibers using electrospinning technology, which have been used in products such as screen windows, masks and filter cartridges. Yu Miao introduced that in terms of dust filtering effect, electrospinning nanofiber materials can filter PM0.3 (solid particles or droplets with a diameter less than or equal to 0.3 microns) up to 99% or more, and achieve traditional filtration. less than half the pressure drop. As far as masks are concerned, the lower the pressure drop, the lower the resistance, the better the ventilation effect, and the better the smoothness of human breathing; in the case of filter cartridges in the industrial field, the greater the resistance, the stronger the blower will be. The more energy is consumed, the lower the pressure drop and resistance, the more energy is saved, and the use of nanofiber materials can save a third of energy. From laboratory to industrialization: Internationally, professional electrospinning nanofiber production equipment and solution suppliers appeared around 2010. For China, low yield and poor quality controllability have always been the primary problems for nanofibers to move from laboratory to 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’It is good to open up the international market.”Academician Xiram introduced that the project is positioned as China's No. 1 supplier of integrated industrial solutions for new electrospinning nanofiber materials, as well as the industrialization of new nanofiber materials in the fields of energy, electronics, biomedicine, chemicals and the environment and functional textiles development. To this end, based on the research results of nanofibers at home and abroad, Ponada Technology starts from the most critical functional indicators such as the strength of nanofibers, so that the technology can be brought to the market. It is worth mentioning that Ponada Technology also has the only mass production line of electrospinning nanofibers in China, which is used for mass production of nanofiber films in factories and workshops.“The positioning of the enterprise itself is a technology exporting manufacturer, and the output is equipment, raw materials and production processes.”Yu Miao introduced that the first step of the project is mainly for the development of civilian products such as screens and masks; the second step is for the development of filters, filter elements and filter cartridges for industrial water filtration, seawater desalination and air filtration, and the third step is the development of medical equipment. Electrospinning nanofiber technology can also help to upgrade lagging capacity.“As far as ordinary gauze is concerned, the price of one square meter is only a few dollars, the profit is very low, and it consumes a lot of labor and energy. Our medical anti-haze gauze, the general market price is 200 yuan to 400 yuan per square meter, and the highest price is 800 yuan to 1,000 yuan, which brings new vitality to the traditional industry.”Zhu Qinwen, deputy general manager of the company, introduced. At present, the company's first-phase product anti-fog screen window has cooperated with China's largest screen manufacturers to promote products. It is initially planned to promote this technology in Hebei first. The product has been mass-produced in November this year, and the order has exceeded 20,000 square meters. . In addition, with the addition of electrospun nanofiber products such as anti-smog masks and electrospinning guns, the project's sales revenue this year will exceed 5 million yuan, and it is expected that the cumulative sales will exceed 100 million yuan in the next three years.
The Heat Contact Machine GT-C101 is a specialized testing instrument designed for evaluating the heat resistance and thermal protective performance of gloves, protective clothing, and other heat-resistant materials used in high-temperature environments. In industries such as smelting, casting, welding, and glass manufacturing, workers are frequently exposed to intense heat, making accurate testing of contact heat resistance essential for ensuring safety and compliance.
GT-C101 simulates real working conditions by measuring heat transfer delay and thermal transmission under instant contact with high-temperature surfaces. Fully compliant with EN 407, EN 702, and ISO 12127-1 standards, this machine provides precise, repeatable data for manufacturers, laboratories, and research institutions. With high-temperature capability up to 500°C, advanced calorimetry, digital monitoring, and adjustable contact speed, the Heat Contact Machine GT-C101 is an indispensable tool for developing and certifying next-generation PPE and heat-insulation materials.
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.
