The quality of air hygiene in the car is closely related to public health. Recently, Shanghai Lekong Net Health Technology Co., Ltd. donated 50 air treatment machines the size of water cups to Shanghai Jinjiang Automobile Service Co., Ltd., which provided a strong guarantee for the health of front-line sales personnel and passengers. This virus killing device, which has been tested by the P3 laboratory of the Jiangsu Provincial Center for Disease Control and Prevention, is expected to be promoted and applied to private passenger cars to escort the health of more people.
According to reports, this batch of donated air treatment machines uses De-fict2 slow-release virus-killing materials developed and produced by Lekong Net. Its scientific principle is based on the strong oxidation of the gas-solid interface, when the strong oxidant meets the virus, it will denature the protein shell of the virus, and let its internal nucleic acid oxidation decomposition, thereby killing the virus. Strong oxidants also react with formaldehyde and other VOCs (volatile organic compounds) in the air, producing carbon dioxide and water without secondary release.
In the first half of 2020, Lekong Net initially completed the research and development of materials for formaldehyde removal and other VOCs, and submitted an application to the BSL-3 Laboratory (P3 Laboratory) of the Jiangsu Provincial Center for Disease Control and Prevention to test and kill the new crown virus. After testing, according to the "Laboratory Evaluation Standards for the Disinfection Effect of The New Coronavirus" test standard, De-fict2 materials can completely kill the new coronavirus within 0.5 minutes.
On this basis, the R&D team designed and processed De-fict2 slow-release virus killing materials into filter purification modules suitable for air purifiers, HVAC systems, fresh air systems, personal care products and other equipment suitable for air purifiers, buildings and automobiles, and can realize the interception and killing of harmful substances such as viruses by replacing the filtering and purification modules of these equipment without changing the structure of air purification equipment.
It is reported that the first generation of Air Treatment Machine of Lekong Net has been applied to Jin jiang automobile's state guest fleet and business travel official vehicles, and has achieved good use results in the most intuitive odor removal. The company said that based on customer needs, they will develop more products suitable for different scenarios as soon as possible to solve the problem of human-machine coexistence and elimination, and contribute to the prevention and control of the epidemic.
This type of equipment has broad application prospects in the field of private passenger cars. At present, most of the domestic private cars use activated carbon packages to remove odors. Formaldehyde and other VOCs are adsorbed inside the grid of HEPA (High Efficiency Air Filter) and in the porous structure of activated carbon, which will produce secondary release under certain temperature conditions, and after adsorption saturation, the adsorption effect will be rapidly reduced, and the adsorbed substances will be released. De-fict2, a new material, has no problems in this regard, and after reacting with formaldehyde and other VOCs, it produces carbon dioxide and water, and does not produce secondary release.
