    ②、betway必威777工作原理类似于照相机的底片暴光,就是将图经过光源的照射暴光在底片上,这种底片叫"菲林片".然后冲洗显影.假如需要印刷的话就将菲林片作为母片,通过光源照射对PS版进行暴光,PS版就是薄铝板上面涂上感光材料. betway必威777用的蓝光是一种可见光,准确地讲应该是介于蓝光和紫外之间的紫蓝光,波长420nm,这种光对人体的伤害很小,不需要做什么防护,因为它的强度根本比不上太阳光下的强度,长时间照射对人体没有影响,长波紫外线(400~350nm)会对人体皮肤黑色素产生沉淀,但也要达到足够的强度才能起作用。
    ②、The working principle of the blueprint printer is similar to the exposure of the camera\'s film. It is the exposure of the chart to the film through the exposure of the light source. This film is called "film film." Then it is developed. If it needs to be printed, the film is used as the master film. Exposure of the PS plate through exposure to light sources. The PS plate is coated with a light-sensitive material on a thin aluminum plate. The blue light used in the blueprinter is a visible light. It should be precisely the violet blue light between the blue light and the ultraviolet light at a wavelength of 420 nm. Seed light damage to the human body is very small, do not need to do any protection, because its intensity is simply not comparable to the intensity under the sunlight, prolonged exposure does not affect the human body, long-wave ultraviolet (400 ~ 350nm) will produce melanin in human skin Precipitation, but also to achieve sufficient strength to work.

    ③、If you take a long time to operate the blueprint machine eyes will cause discomfort, if you want protection, you can bring sunglasses.


    说明解释:①betway必威777是一种将描图纸上的图形通过曝光手段将图形转移到感光材料上,即晒图纸上,再通过显影洗出蓝图的设备。

                    ②晒图纸本身对人没有危害,晒图纸就是在普通白纸上加涂了药水,来适合晒图用。只要不往嘴里放就没事。但是用有氨betway必威777晒完图之后的晒图纸,会挥发出带有刺激味的氨水味,不过对人体没有太大危害。
