编辑同志: 我厂使用天津复印机厂制造的CDOG × 65型复印机,在灌氨水、晒熏图纸、整理图纸时,氨气逸出较多,对操作工人刺激很大。为保护工人的健康,降低工作间的氨气浓度,我们想对晒图工作进行改革,但不知氨气浓度如何测定?请贵刊予以介绍。 贵州省凯里200信箱设计科 洪强洪强 Edit comrades: I plant in Tianjin copier factory manufacturing CDOG × 65 copiers, irrigation in ammonia, sun smoked drawings, finishing drawings, ammonia escape more, a great stimulus to the operating workers.
