At present, laser technology has entered the fields of people's work, study and life more and more widely. People have more and more opportunities to contact copiers and photocopying products, but their influence on human health has not received enough attention. According to foreign research reports, laser printers and copiers have a certain impact on human health. Below, Xiaobian has made some summary and recommendations, and hopes to give you a reference. â—The impact on human health - copy machine articles 1. The most widely used one is carbon copying machine, which uses dry and wet developing powder. The dry developing powder is made of extra grade carbon black in which the cyclic aromatic hydrocarbon has carcinogenic effects. However, since the carbon black polymer material is miscible and wrapped, the dry developing powder is rarely decomposed during the copying process and is very stable. Scientists have found that the developer contains trace amounts of nitroguanidine, which has the ability to alter the normal structure of the chromosome, which can lead to tumors. After technical improvement, the content of nitroguanidine in the current dry developer powder has been greatly reduced, and its carcinogenic effect has not been detected by conventional methods. The wet developing powder disperses carbon black in a hydrocarbon solvent, and the aliphatic hydrocarbon having 10 to 20 carbon atoms contributes to tumor growth. Due to the low boiling point of the hydrocarbons used, they are volatile and poor ventilation can cause harm to long-term contacts. 2. The developing material of the carbonless copying machine is highly irritating and can cause diseases such as skin, eyes, respiratory tract and nervous system. In addition, carbon-free copying can also release some substances that may cause cancer during the copying process. 3. When the copier is working, the copying room has a certain amount of ozone due to the action of static electricity. Ozone has a strong oxidation effect. In November 1988, the results of a survey released by the National Institute of Public Health in Japan showed that ozone concentrations were sufficient to harm the human body where copiers were frequently used. Through the monitoring of some offices and public libraries using copiers, the ozone concentration reached 0.12 mg/l 0.5 m from the copier. These ozone are produced by chemical reaction of air with high voltage components in the copier. Ozone has a high oxidation effect, which can be converted into nitrogen oxides, which is highly irritating to human respiratory tract. Ozone has a large ratio and slow flow, and the ventilation room is poorly ventilated due to dustproofness, which may cause the copier operator to have a "copier syndrome". The main symptoms are dry throat, chest tightness, cough, dizziness, headache, vision loss, etc. In severe cases, toxic edema can occur, and it can also cause symptoms in the system. In addition, some skin coping symptoms of copier operators may also be associated with contamination of the contact copy paper, as the copy paper contains some special added ingredients and produces paper dust during the copying process. â— Impact on human health - laser printer articles Laser printers are as dangerous as smoking and can cause cancer. According to foreign media reports, the results of the International Air Quality and Health Laboratory (ILAQH) scientists show that some of the harmful particles released by laser printers are equivalent to the harmful particles released by smoking, and can cause cancer in severe cases after inhalation. ILAQH tested the emissions of 62 laser printers and found that 27% of printers emit harmful particles. Because of the tiny size of these particles, human lungs cannot be directly filtered. Moreover, some of the harmful particles released by the printer are comparable to the harmful particles released by smoking. In general, the harm of laser printers mainly includes the following aspects: Toner: Toner particles are not difficult to be thawed and excreted in the human body. Long-term inhalation or inhalation in a single dose can easily cause respiratory illness, and the toner is somewhat toxic. Laser: The harm of the laser to the human body should not be explained by me, but the general laser printer has protective measures, as long as it does not make its own claim to remove the cover and print it without any problem. Odor: The printer is set to use high-temperature melting toner particles. It has a certain odor when printed. This smell is harmful to the human body. Therefore, it is not allowed to stand next to the printer when printing. It is best to place the printer. In a place far from the human body. Radiation: Electrical products are inevitably radiated. The printer circuit has a high-voltage generating circuit and a high-temperature generating circuit. Do not touch the high-temperature and high-pressure parts with your hands. Electronic products are inevitably radiated. The printer circuit has high-voltage generating circuits and high-temperature generating circuits. Do not touch the high-temperature and high-voltage parts with your hands. â—Method of prevention Those who have been engaged in copying work for a long time should pay attention to strengthening labor protection. Those who have the conditions can install exhaust fans or exhaust pipes in the studio to allow indoor ozone and nitrogen oxides to be discharged outside. Dust removal equipment should be installed in rooms with large copiers and heavy workload to reduce dust. Alcohol should be used when cleaning the developer. Do not use benzene solvents. The device should be covered with an object to block the stimulation of the strong light pair. Operators should also increase vitamin E intake to protect cell biofilms from nitrogen oxides. In addition, respiratory diseases and insomnia, dizziness and pregnant women, it is best not to operate in office equipment. â—Green office equipment Health office products are getting more and more people's attention. Users are choosing more healthy and environmentally friendly products. Manufacturers are also constantly introducing "green products". For example, non-fluorine refrigerators replace fluorine refrigerators, and non-radiation LCDs eliminate radiation CRTs. The concept car replaces the super-standard car and so on. LED equipment introduced by office equipment manufacturers not only provides users with high-speed and efficient printing functions, but more importantly, it is more energy-saving and environmentally friendly. LED (Light Emitting Diode) technology, also known as LED technology, is one of the most advanced imaging technologies in the world. After continuous research by the scientific community and professionals, replacing new chemicals and improving internal systems, LEDs have never been more bright and brighter, and the use of light sources is more abundant. Moreover, LEDs can produce high-brightness light sources directly under low-voltage conditions, and ozone, which is inherently required to operate at high voltages in conventional laser printers, is no longer available. As a result of energy-saving and electricity-saving without ozone, LED color printers have emerged as a new generation of health products, and have been promoted and applied in the European market where environmental protection is highly valued. Editor's Note: In fact, these hazards are only general hazards. Don't feel terrible. Everything has a good side and a bad side. The mobile phone and computer you use are all electromagnetic radiation. You can't because of this. The harm is far away, and the protection of the current products in these aspects has been done very well at the time of design, and now the laser printing technology is very mature, not too worried.
