Wei Wei, the benefits of a product to create an air disinfection technology patents wisdom made fast and effective removal of disinfection and purification of five integrated pollution reduction performance standards designed to eliminate the surplus value of affordable shared interest in creating a little money into a big return in exchange for key health products sterilization and disinfection and purification technology roadmap principle 1, product sterilization technology roadmap Scope 1, hospitals: for Ⅱ, Ⅲ environments. Such as operating theaters, wards, clinics, maternity wards, supply room, burn ward, intensive care room. 2, first aid: Products and laminar combination, can adapt to the army military exercises and earthquake emergency rescue patient use. 3. Pharmaceutical: sterile rooms, laboratories. 4, food plants: laboratory, packing room technology and production workshop. 5, in public places: offices, meeting rooms, libraries, hotels, office buildings, entertainment venues, waiting room, schools, kindergartens and families. Dongguan City Environmental Technology Co., a patented technology in its research and development of all kinds of central air purifier: central air conditioning return air purification device purifying device company, ducted central air purification device purifying device, plug-in light hydrogen ions purification central air conditioning purification equipment principle, fan coil cleaner, etc. Features: semiconductor surface hole - electron recombination from photocatalytic reaction mechanism can be seen, when an energy greater than or equal to the band gap of a semiconductor light irradiation, valence band electrons (e-) are excited transition to the conduction band, while holes generated in the valence band (h +). To suppress electronic - complex voids on the need to study a way to control its complex. Hole - electron pairs generated is to give it a potential transition, can use the power-assisted methods to control, to hole - electron separation. Supply from central air-purifying charge attraction principles of physics, can inhibit the electron transfer. Application of this principle, when the transition of power at the same time give it a migration in the opposite direction, to achieve this breakthrough of principle, the project is focused on solving key technology.
