Is selenium powder toxic?

As people's work pressure in modern society is getting higher and higher, many friends will use printers and copiers at work, so it is necessary to regularly add some selenium powder to the machine so that the machine can operate more normally. However, many friends feel uncomfortable on their skin when adding selenium powder. So is selenium powder toxic? In response to this question raised by everyone, let me share with you some information in the following time.

Selenium powder is the toner used in copiers. The toxicity comes from the resin and conductive (static) agent in it. When the copy is completed and passed through the heated roller, harmful gases will be released. It is best to place it 3 meters away from the work place and ventilate it.

As long as it is used in a ventilated environment, the harm is not great, but some people have severe allergic reactions, so special attention should be paid. In particular, it is best to wear a mask when replacing the toner cartridge, wash your hands immediately after contact with toner, and avoid direct contact with mucous membranes.

2. Toxin-free control of toner: The various raw materials of toner can be non-toxic if they are manufactured in a standardized manner and used in a sealed state (such as original manufacturers or Mitsubishi toner, Bachuan toner, Huazhong toner, etc.). According to AMES-testing, various bottled loose powders on the market are difficult to meet the non-toxicity requirements due to constraints such as production technology. 3. Some toners on the market are toxic. Many bulk or bottled toners on the market (origin and factory address unknown) have large deviations in particle size, ranging from 5 to 12 microns, due to constraints of the factory's equipment, process, raw materials, environment and other factors. The degree of polymerization of polyacrylate-styrene copolymer, that is, the molecular weight and distribution are very critical. If it is too large, it cannot be fixed (causing a false blackness), and if it is too small, small molecules of toxic styrene gas will escape. If the human body works in an environment close to a printer using such toner for a long time, it will cause harm to the human body, and the chance of cancer will be 4% higher than that of normal people. At the same time, it will contaminate the OPC drum and MR magnetic roller, causing poor printing of the toner cartridge. Toner is divided into magnetic toner and non-magnetic toner, and the composition ratio of toner used in each machine model is different. Many bottled toners or bulk toners are not differentiated and only use one type of magnetic toner mixed together. When the wrong toner or inferior toner is used, it is not only harmful to the human body and the environment, but also damages the printer and reduces its lifespan. 4. Potential harm of filling toner to human health. When toner cartridges are filled with toner without strict environmental protection, small particles (invisible to the naked eye) will fly in the air. After repeated contact and inhalation by the human body, the chance of cancer will be about 10% higher than that of normal people. After the surface modifier polyethylene/polypropylene paraffin is inhaled into the body, its small molecular particles will be absorbed into the blood circulation system and eventually planted in the kidneys, and are extremely difficult to be excreted (because toner is insoluble in water), thus inducing kidney stones and other diseases The chance is 3 times higher than that of normal people.

I believe that through the above understanding of all of us, the majority of friends have a deeper understanding and more proficient grasp of whether selenium powder is toxic. Of course, I would like to remind everyone that when we add powder to the toner cartridge, we must wear a mask and some ultra-thin rubber gloves on our hands, because selenium powder will have a certain harmful effect on our skin, and it will also have an adverse effect on our lungs and liver.
