What Is Carbon Powder?

Toner, also called toner, is a powdery substance used in laser printers to image and fix on paper. Black toner is composed of binder resin, carbon black, charge control agent, and external additives. Pigments of other colors need to be added to the color toner.

Toner

Many toner cartridges can be re-used by the user after the original toner is used up, so there is a separate toner on the market. By adding toner by yourself, the cost of user consumables will be greatly reduced. Since the toner cartridge is a sealed disposable consumable, adding toner by yourself will damage the sealing performance of the toner cartridge and cause powder leakage. The toner particles are generally measured in micrometers. If it is scattered in the air, it will be invisible and cause use Pollution of the environment and the office environment has led to an increase in PM2.5.

Toner is mainly used in printing machinery

To meet different needs, toner production is developing in the direction of refinement, colorization and high speed. Toner manufacturing mainly uses crushing and polymerization methods:

Nowadays, laser printers and electrostatic copiers commonly used in offices release various fine particles of toner, which pollute indoor air. Nowadays, such devices can be seen everywhere from home to work. It is these machines that release a lot of fine particles, heavy metals and harmful gases, which have made various office syndromes quietly spread in countries around the world. The blood image changed.

As early as 11 years ago, a study published by Spanish scientists in The Lancet warned that the dust released from the drum of an electrostatic copier can cause lung disease. A year later, Epa, a US environmental research agency, came to a similar conclusion. In 2003, the Dortmund Labor Medical Protection Agency in Germany conducted a test that allowed the test mice to inhale the ink drum dust. Soon, the test mice developed tumors in the lungs. but,

For nearly a year, scientists have tracked the physical conditions of 60 volunteer participants to study how the physical conditions of these participants who regularly come into contact with toner will change under daily working conditions. In addition, scientists also conduct regular physical examinations of these participants, and regularly detect the concentration of various fine particles, floating objects and microorganisms in the office air. The research cost is too high. For this reason, scientists have suggested that the best way is to regularly check the office air and perform physical examinations on people who already have certain symptoms.

If it is determined that the particles released by the ink drum are toxic, Germany will require manufacturers to indicate on the equipment shipped in the future whether the chemical composition of the materials used will harm the human body. Different European countries have different practices. For example, in Sweden, laser printers must be installed in rooms with ventilation equipment; in the Netherlands, fine particle filters must be installed when using these equipments. Therefore, German experts believe that Germany should take similar measures.
