晒图作为工程设计和工程施工的重要工具,自始至今发挥着不可替代的作用。然而在蓝图打印的数字化、网络化发展之前,传统氨式晒图、激光晒图存在着几大问题。1)有氨晒图机以类似于感光胶片的晒图纸利用氨水熏制定影成像,难闻的氨水味会让人感到不适。此外,由于极易影响周边居民的生活,晒图工场的位置也比较难设。而工程激光打印机在生产过程中带来的粉尘、辐射、臭氧等,也会对人体健康造成直接威胁。2)晒图是非常繁重且单调重复的人力劳动,加上工作环境恶劣,人员流动频繁;同时,一台有氨晒图机需要多人进行操作,如果时间
As an important tool in engineering design and construction, drawing has played an irreplaceable role from beginning to end. However, before the blueprint for digital printing, network development, the traditional ammonia-based imaging, laser imaging there are several major issues. 1) There are ammonia tanning machine with a photosensitive film similar to the blueprint of the use of ammonia smoke fixation fuzzing imaging, bad smell of ammonia can make people feel uncomfortable. In addition, the location of the paint shop is also more difficult to set up because it can easily affect the lives of the surrounding residents. The engineering laser printer in the production process brought dust, radiation, ozone, etc., will also pose a direct threat to human health. 2) Shade is a very heavy and monotonous repetitive manual labor, coupled with harsh working conditions, frequent staff turnover; at the same time, a tanning machine with ammonia requires more than one person to operate, if the time
