Photocopying in popular Office equipment.Getting closer everyday use. Most of the heat, or static electricity. The original document is read and print out manuscript document.Information from the Web site midoa.com indicates that artificial intelligence people who first Copier world is Chester Carlson (Chester Carlson), physics, United States residents. Inventors who have learned to master the light material. He knew that when moving to the material causing the battery.Carlson has taken this principle to the entire generating machine, copy the application easier and cheaper is to use offset printing system and method roniao, which contains the steps that are more complex and difficult to type a lot so it is worth.He has been studying the beneficial from the research work of Paul Salen Yi. Physics students who discover the Hungarian people before him, the light will be increased to bring the static electricity of the object. While Carlson discovered that light itself with some chemicals, such as sulfur will cause the substance to become.His knowledge of both applied in the process of creating images with static electricity.Carlson and his trial. The name Otto (Otto Kornei) courses help prepare a sheet of zinc coating with sulphur, for use as a material light microscope glass slides using that contain text written "10-22-38 Astoria" serves as the source for a trial copy.The main outline of the work underlying the first Copier world. Start by rubbing the handkerchief to the surface coating on zinc sulfur, which quickly add up to cover the chup sulfur and then taken the original slide to mesh at the top of the plate, zinc-coated, sulfur lamps shining through the plate and slide it from the top down.According to this principle, when the light hits on the skin of sulfur will cause a negative charge, which would go against existing prachubuak. The handkerchief to rub against the sulfur quickly. But the letters on the block slides, light. Make the surface under sulfur letters not exposed.When I put the toner into the original slides and separate out blow excess toner on zinc coating of sulfur left. What's left on it is almost identical to the original.Intelligent of Carlson and Otto made a copy from the first copy of the world begin. When October 22 last year, when 77 2481From that day to this day even though the copier will be developed continuously until it has to work very fast, and the more modern, recently. The Office of environmental health public health Department issued warnings to realize the greatest sorrow in the Copier.By specifying that the harmless individual who could get to the substance from the copier is ozone (Ozone), which are mainly caused by discharging electricity and paper roller, and some is due to release the beam power tube UV coming from the height of the copier that the UV light, gas, oxygen in the air as ozone.Ozone gas is decomposed into normal oxygen. Within 2-3 minutes, but the rate of decomposition of ozone, depending on the duration of ventilation. Surface ozone and temperature object which will disperse faster in high temperature. Charcoal, Activated Carbon is a charge or as an aid to ozone degradation.Although the new version of the copier are usually Activated Carbon Filter types trapped filters to help break up ozone before released outside the machine.But to get the levels of ozone in concentrations up to 0.25 ppm. Long continued to cause eye irritations Nose, throat, Dizzy head, loss of smell, particularly those recognized as asthma. Do not touch the ozone because of the potential danger to the lungs.Next is the greatest the toner in the Copier, which contains both powder mixed with carbon black plastic resin. In the copier toner and the melting system in additives, petroleum. In a wet system, copierThe two are harmful chemicals need to be careful when refilling, ink, toner and ink, both failed, as well as clean the dust or toner used container should be left in the closed mitchit.The third danger is that chemicals such as cadmium sulfide seleniam. Zinc oxide and polymer coating that is often at the wheel in the photocopier. These volatile chemicals released during copyingFor example, if seleniam inhale into the body to cause respiratory irritation on eye tissue mueakkrapho food. If you get into the body in large quantities or for a long period of time will cause symptoms of fatigue, tongue. Indigestion and head get dizzy in high concentration levels will be harmful to liver and kidney.Cadmium, though, will be released from the copier in a quantity of less than seleniam, but since cadmium is a carcinogen, so there is a danger greater than other UV radiation is the greatest seleniam from a high power tube in the Copier. When I get the most often or for a long time to make people view Flash head pain and inflammation of the cornea rash itchy skin.Previously, both the m.d. rush rush Nakata Nakata nawin รมว. public health and former m.d. pornthep Siri WANA, wedding. Director Public Health Department has come out.The copier could cause health impacts per user in the long run, especially for those who want to act because of photocopying documents taken with both chemical and odor from the air while copying may affect the health of people who are active in the long term.The Ministry of public health and therefore it is recommended that users should know how to prevent the copier itself, such as when you copy every time it should close the lid well with thai install exhaust fan in the room should wear gloves and tanks masked all chemicals during weather or move the toner.The used toner or the toner that spilled along the floor while filling. Need to take to get rid of the closed container in your mitchit. There should be regular maintenanceMore importantly, it is possible to install a separate copier at the corner of the room, which is far away from the workers. Those who have a duty to involve.
