The spread of the epidemic promotes the outbreak of demand in the sterilization and disinfection industry
In February 5, 2020, the national health and Health Committee released the New Coronavirus pneumonia diagnosis and treatment plan (trial version fifth). The plan pointed out that New Coronavirus is sensitive to ultraviolet and heat, and 56 degrees Celsius 30 minutes, 75 degrees ethanol can effectively inactivate the virus.
The epidemic has spawned a large disinfection market. Ultraviolet disinfection lamps are widely used in the fields of ambient air disinfection, drinking water and sewage disinfection, clothing and tableware surface disinfection and so on. The outbreak of the epidemic has driven the market demand for ultraviolet sterilization. This epidemic has popularized and paid attention to consumers' awareness of ultraviolet sterilization, which provides a good development opportunity for UVC.
The epidemic situation makes people pay more attention to health, and with the continuous improvement of ultraviolet lamps by manufacturers, it is closer to life. It is expected to enter people's life as a health product, resulting in continuous demand.
Many studies have shown that UVC semiconductor can effectively kill coronavirus. German UV technology developer good group recently announced that short wave UVC irradiation can effectively inactivate New Coronavirus. The results show that its UV unit can kill coronavirus within a few seconds, with a bactericidal rate of 99.99%. In May 27th, Miyazaki University announced that the joint test showed that the short wave UVC semiconductor lamp installed on the machine could effectively inhibit New Coronavirus's infectivity and kill it, which could reduce the infectious power of New Coronavirus by more than 99.9%. Columbia University research shows that far UVC light can kill seasonal coronavirus transmitted by air droplets, and the inactivation rate is 99.9%.
University of Milan, IRCCS foundation and Italy national astrophysics Institute published the latest research results in June 5, 2020 by the world's top medical paper preprint website medrxiv: UVC ultraviolet light can effectively inhibit New Coronavirus. The researchers used different power UVC ultraviolet light sources to irradiate COVID-19. The experimental results showed that the ultraviolet radiation dose reached 4mJ/c m at lower infection multiple index MOI=0.05, which could kill COVID-19. Even in extreme cases, COVID-19 infected with a composite index of up to MOI=1000 has an effective UV radiation dose of 16.9 mJ / C M, which can effectively inhibit New Coronavirus. According to this research report, the most conservative calculation is that using 30W's UVC ultraviolet light, 35S can kill COVID-19.
Minamata convention falls to the ground and accelerates the process of mercury lamp replacement
Minamata convention was officially implemented, and UVC accelerated the substitution of mercury lamps. The Minamata convention adopted by the United Nations in 2013 has officially entered into force in 2017. Nearly 140 States parties are required to refrain from producing, importing and exporting mercury containing products from 2020. As a major country in traditional mercury processing and manufacturing and mercury pollution, the Chinese government has actively implemented the requirements of the Minamata convention. The Chinese government has successively promulgated a series of policy documents such as the list of toxic chemicals strictly restricted by China and the list of chemicals under priority control (the first batch), which put forward clear requirements for mercury control.
Mercury lamp or commonly known as mercury lamp is the most mainstream product of ultraviolet disinfection, curing and exposure. Even fluorescent lamp and energy-saving lamp are also one of the largest applications of mercury lamp. Compared with mercury lamp, the service life of LED lamp can usually exceed 20000 hours, which is more than 10 times that of traditional mercury lamp. Moreover, it has fast starting speed and small volume. It can be designed to meet different application needs. Compared with mercury lamp, LED lamp has higher application flexibility. More importantly, UV LED will not cause environmental pollution and consume less energy. It is more environmentally friendly and safe than mercury lamp. In the long run, UV LED, as an ultraviolet light source, will become the mainstream of the future market and realize the substitution of mercury lamp.
UVC semiconductors are widely used downstream, and 2b & 2C & 2G applications open up growth space
UVC is widely used downstream. From the perspective of application scenarios, the application direction of UVC can be divided into surface sterilization, air sterilization, static water sterilization and flowing water sterilization.
From the perspective of time dimension, the application direction of UVC can be divided into short-term market and medium and long-term market. The short-term market includes household air conditioner, humidifier, air purifier, intelligent garbage pass, electric toothbrush sterilization box, water dispenser, ice maker, intelligent toilet and food preservation; The medium and long-term market includes commercial air conditioners, vertical air conditioners, sterilization of mother and baby products, sterilization of overflow direct drinking water, etc.
2B & 2C & 2G many applications open growth space:
2B & 2C application: since the implementation of industrial upgrading policy in China, the concept of consumption upgrading has been deeply rooted in the hearts of the people, and product intelligence and health concept products have been more and more sought after by consumers. In addition, novel coronavirus pneumonia promotes the B and C users to raise their awareness of sterilization and anti virus. Residents are more concerned about their health. Maternal and infant sterilization products, sterilization refrigerator, disinfecting washing machine, sterilization air conditioners, sterilization toilets and other highly health-related products are more popular with consumers, and are expected to accelerate the development of UVC semiconductor 2B&2C applications.
2G application: driven by the epidemic situation, the demand for sterilization and disinfection in public places has increased significantly. Due to the relatively closed space in public places, such as high-speed railway stations, subway stations and airports, the crowd gathered, the air was not circulated, and the risk of virus infection was high. Disinfection and sterilization is particularly important in the prevention and control of the epidemic situation. UVC semiconductor can play an important role in sterilization and disinfection in public places by virtue of its safety, environmental protection, compactness, high efficiency, low consumption and no chemical residue. It will be more and more used in the future.
China has a complete UVC semiconductor industry chain, which is similar to the traditional LED industry chain. The UVC semiconductor industry chain can be divided into chip, packaging, downstream lamp application and other fields. Compared with traditional LED, UVC semiconductor has higher requirements for technology and higher industry threshold. UVC semiconductor adopts high-frequency deep ultraviolet light source, which puts forward higher requirements for chip, packaging technology and material performance.
In the downstream of UV LED, it can be subdivided into three applications: uva semiconductor curing, UVB semiconductor phototherapy and UVC semiconductor sterilization and disinfection.
UVA semiconductor curing: mainly used in the field of printing and wood coatings. The wavelength is mainly UVA. At the same time, it is used in combination with UVB and UVC bands.
UV-B is mainly used in home beauty instruments and UV-B.
UVC semiconductor sterilization: novel coronavirus pneumonia has accelerated the application process of UVC semiconductor sterilization products.
