What are the hazards of carbon powder to human body

I have always thought that toner is made of carbon, but now I know that it is not. Most toners are made of resin, carbon black, charging agent, magnetic powder, etc. The toner is melted into the paper fiber at high temperature, and the resin is oxidized into a gas with a pungent odor, which is what we call ozone. It has no benefits for the human body itself, but it will have a bad effect on the human mucous membrane. So what are the hazards of toner to the human body? Let me introduce it to you below, I hope it can help you, let's take a look.

1. The main components of magnetic toner (toner) for laser printers: F-Fe3O4 crystal powder (PLGMENT): 20-30% Polyacrylate-styrene copolymer: 50-60% Charge regulator CCA: 10-20% Fluidizing agent SiO2 and other surface modifiers Polyethylene/polypropylene paraffin.

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, Bachuan, 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. The general toner on the market is toxic. Many bulk or bottled toners on the market (with unknown origin and factory address) have large deviations in particle size, ranging from 1 to 10 ?/SPAN, due to the constraints of the factory's equipment, process, raw materials, environment and other factors. The degree of polymerization, i.e. the molecular weight and distribution of polyacrylate-styrene copolymer is 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.

The harm of toner to the environment is relatively small, so the use of toner in life is very common. Many factories use toner as a production material, so it is very common in life. The harm of toner to the human body is not that great. As long as we pay more attention in daily life, we can avoid the harm. Everyone must remember to protect themselves.
