Zhang Yanxia (Texas City Health and Epidemic Prevention Station) reports: dipping often xylene as a diluent, after dipping and drying more use of natural drying or oven drying, resulting in xylene emitted and pollute the environment; Far-infrared drying oven dipping the workpiece after dipping, so as to cure the xylene pollution of the environment. Pre-treatment dipping operation is at the corner of the assembly workshop, covering an area of less than 50m ~ 2, open with 2 electric furnace drying, no ventilation, the average concentration of the tested xylene 343.8mg / m ~ 3, the highest 6.84 Times
