室内空气净化器市场应用
Market application of indoor air purifier
随着经济的迅猛发展，人们对生活质量要求的提高，室内环境发生了巨大的变化，大量建筑材料和装潢材料造成了室内空气的污染，同时这些材料中各种化学添加剂使用量也在不断增加，使得新装修房间内空气中挥发性气体浓度高于室外，甚至高于工业区。常见的室内污染物有甲醛、甲苯、氨等挥发性气体，固体颗粒物质以及微生物污染物等。医学科研人员指出，这些污染物对人体健康有着极大的威胁，尤其是挥发性气体（voc），长期吸人会对人体的呼吸系统、心血管系统及神经系统有严重的危害，因此解决室内环境问题就显得尤为重要。室内空气的净化技术主要有吸附、过滤、等离子体、静电、离子、膜分离以及光触媒等，而纳米TiO2：光触媒技术是兴起的一项新技术，它可以利用包括太阳光在内的各种途径的紫外光，在室温条件下将各种挥发性气体予以光解，将微生物灭活等，从根本上解决了室内污染物对人体的危害。由于该项技术具有能耗低、操作简单、反映条件温和等优点，尤其对一些特殊的污染物具有极高的去除率，而且没有二次污染，因此采用纳米TiO2 光触媒技术进行空气净化已经成为治理环境最有前途的方法之一，同时也为室内空气净化提供了一种行之有效的方法。
With the rapid development of the economy and the improvement of the quality of life, great changes have taken place in the indoor environment. A large number of building materials and decorating materials have caused the pollution of indoor air. At the same time, the use of chemical additives in these materials is also increasing, making the air in the newly decorated room more volatile. The degree is higher than the outside, even higher than the industrial area. Common indoor pollutants are formaldehyde, toluene, ammonia and other volatile gases, solid particulate matter and microbial contaminants. Medical researchers point out that these pollutants have a great threat to human health, especially volatile gases (VOC), which will seriously harm the human respiratory system, cardiovascular system and nervous system for a long time. Therefore, it is very important to solve the indoor environmental problems. The purification technology of indoor air mainly includes adsorption, filtration, plasma, electrostatic, ion, membrane separation and photocatalyst, and nanoscale TiO2: photocatalyst technology is a new technology. It can make use of ultraviolet light in various ways, including solar light, and remove all kinds of volatile gases at room temperature. By inactivation of microorganism, the harm of indoor pollutants to human body is fundamentally solved. Since the technology has the advantages of low energy consumption, simple operation and mild reaction conditions, especially for some special pollutants, it has very high removal rate and no two pollution. Therefore, the use of nano TiO2 photocatalyst technology has become one of the most promising ways to control the environment, and also for indoor air. Gas purification provides an effective method.
