生产环境中的电离辐射、人工紫外线、机械设备的转动、织物摩擦、化学反应、火焰燃烧以及工业生产中采用的射流、束流技术、压缩空气、喷雾风扇、喷漆或液槽通入蒸气等人为因素,均可使空气分子发生电离,形成带电荷的阴离子和阳离子的现象,称之为空气离子化。空气离子化随生产和工艺过程不同,或因粉尘、烟、雾、化学气体的逸出,以及空气的超净化等影响而有差异。如生产环境中有自激放电、电晕放电的车间,象超高压静电除尘、高压电器的短路火花等处空气阴离子增多;开放性火焰、熔融金属、搪瓷涂烧、粉尘飞扬、棉纱化纤织物的纺丝工艺等处空气中以阳离子为多;微电子工业的超净化车间空气中阴、阳离子均明显减少。临床研究和现场观察表明,空气离子的过多、过少、或用、阳离子的比例不当,都可以对人体健康产生不良影响。 Ionizing radiation, artificial UV, rotating machinery and equipment, fabric friction, chemical reactions, flame combustion and jet used in industrial production, beam technology, compressed air, spray fan, paint spray or tank into the steam and so on Factors that can ionize air molecules, the formation of charged anionic and cationic phenomenon, called air ionization. Air ionization with the production and process of different, or because of dust, smoke, fog, the escape of chemical gases, and the impact of air purification and other differences. If the production environment has self-excited discharge, corona discharge of the workshop, such as high pressure electrostatic precipitator, high voltage electrical short circuit sparks and other air anion increase; open flame, molten metal, enamel coating, dust flying, cotton yarn chemical fiber fabric Spinning process at the air to more than cations; micro-electronics industry ultra-purification plant air yin and cations were significantly reduced. Clinical studies and field observations show that air ions too much, too little, or use, the proportion of cationic improper, can have a negative impact on human health.
