How to reduce the damage of laser cutting machine radiation?
Yesterday, I introduced the safety level of laser products. Today, I will take you to understand the damage of laser cutting machine radiation to human body. The radiation caused by the laser cutting machine is not to be underestimated, especially for the human eye can cause blinding damage. So how do we protect ourselves from the radiation damage of the laser cutting machine?
1, the eyes
When you first come into contact with a laser cutting machine, people often like to stare at the cutting head. If you look at the spark from the cut for a long time, it will cause a tingling sensation in the eyes. In addition, during the processing of the laser cutting machine, the emitted laser can make the energy highly concentrated in space and time, and focus on the retina through the refractive medium of the eye to form an image, thus increasing the energy density on the retina by 104~105 compared with the incident energy density on the cornea. In addition, the laser has good monochromaticity and small chromatic aberration in the fundus, resulting in damage to the cornea or retina caused by extremely low laser energy irradiation.
2, the skin
When the laser shines on the skin, if its energy (power) is too large, it can cause skin damage, and long-term exposure may cause burns and scars. This kind of damage can be repaired by tissue. Although the function is reduced, it does not affect the overall functional structure. Compared with the damage to the eyes, it is much lighter, but it must be paid attention.
3. The respiratory system
The high temperature generated by the laser is combined with the gas to complete various processing. At the same time, it also produces a lot of dust, especially when processing some special metal materials, the smoke produced contains a large number of chemical components. Dust will be suspended in the air and harmful to the human body after inhalation.
How to avoid the damage caused by fiber laser cutting machine?
1, the necessary laser cutting machine protective equipment, wear protective glasses to prevent laser damage to the human eye. Other personnel in the work area should not look directly at the laser during cutting.
2. Operators should pay attention to eating more carrots, bean sprouts, tomatoes, lean meat, animal liver and other foods rich in vitamin AC and protein, and often drink some green tea, because these foods can help humans better maintain their eyes. Let the human body be able to better maintain the human body under the condition of laser cutting machine radiation.
3, to have a supporting dust removal device, as far as possible in the air unobstructed environment operation, try to wear masks.
4. When arranging the cutting site, paint the site and wall of the working environment into a dark color to reduce radiation.
5, do not immediately touch the cut parts, so as not to burn the residual temperature.
