Analysis of development trends of UV light curingread count [279] release time：2020-03-16 22:08:00
UV is closely related to our lives, but most of us are not aware of it yet. Today we will briefly analyze the development trend of UV curing. UV is widely used. Take UV light source as an example, in plant lights, gem identification, Photocatalytic purification, UV curing、Protein testing and medical inventions, Medical light therapy, medical testing analysis, Sterilization and disinfection, It is widely used in ink printing, banknote inspection and other fields.
At present, the UVLED market in my country has not yet been fully opened. One reason is that due to the difficulty of technology, many companies that want to enter but have not yet had time to enter this field are deterred. However, as the LED market becomes increasingly saturated and gradually replaced, entrepreneurs who want to gain something in the LED market need not only a vision for discovery, but also strong technical support. The previous National Ultraviolet Light Source and Device Technology Seminar held in Wuxi allowed more than a hundred participants to learn about the latest research results and industry trends, and to feel the unremitting pursuit of technological progress by front-end practitioners.
Application in various oil fume purification equipment
According to a report from Haining Yaguang, the ultraviolet photolysis and oxidation oil fume purification system is currently the most advanced photolysis and oxidation oil fume purification system in the country. In this purification system, a specially designed ultraviolet lamp containing 185nm+254nm plays a core role. It can decompose grease and odors in the kitchen air, and has the advantages of no secondary pollution, reduced fire hazards, small size, light weight, and greatly reduced maintenance costs.
Applications in UV LED light curing systems
UV LED light curing applications include applications in display screens, electronic medical, instrumentation and other industries UV glue Adhesive curing; UV coating curing in building materials, furniture, home appliances, automobiles and other industries; UV ink curing in printing, packaging and other industries... Among them, the UV LED decorative panel industry has become a hot spot. The advantages are that it can produce zero formaldehyde environmentally friendly panels, and saves 90% of energy. It has large output, is resistant to coin scratches, and has comprehensive economic benefits and other advantages.
Application of UV in plant factories
According to Liu Wenke, a researcher at the Institute of Agricultural Environment and Sustainable Development of the Chinese Academy of Agricultural Sciences, closed soilless cultivation is prone to accumulation of autotoxic substances, and TiO2 photocatalysis can degrade root exudates and rice husk degradation products in the matrix cultivation nutrient solution. Sunlight only contains 3% of ultraviolet light, and facility covering materials such as glass filter out more than 60%, making it unsuitable for use in facilities. The low temperature and lack of sunlight in winter for vegetable off-season cultivation make it inefficient and unstable, and cannot meet the needs of factory production of facility vegetables.
The development of artificial light TiO2 photocatalytic system suitable for soilless cultivation in facility horticulture, especially suitable for use in plant factories, is in urgent demand and has huge commercial potential. There are more than 60 artificial light plant factories in my country, and tens of thousands of hectares of multi-span greenhouses are cultivated.
Application in organic waste gas treatment in textile industry
According to reports, the total VOCs emissions from my country's textile industry account for about 30% of the total industrial VOCs emissions. VOCs are one of the precursor substances that generate haze and are an important component in the formation of PM2.5. Photocatalytic oxidation using UVLED as a photocatalytic light source is a better way to treat VOCs. It has the advantages of small size, high catalytic activity, stable chemical properties, low cost, non-toxicity, etc., and has broad application prospects.
