Expanded manufacturing company ( 公司) Provide durable laser printer toner, digital copier toner, color toner, etc. , various models, size, material, welcomed the purchase. Carbon powder polymerization is a kind of fine chemical toner technology, it includes suspension polymerization, emulsion polymerization, detail capsule, dispersion polymerization, compression polymerization, chemical pieces. Printer toner many drums in original toner after use, the user can add after used again, so also is to have separate toner for sale on the market. By adding toner by oneself, will reduce the use of the user supplies cost. Color toner in print, volatile due to residual monomer in the resin is heated, produces the pungent odor, therefore national standards and industry standards of toner TVOC has carried on the strict limits. So as long as you buy printer or nonconforming product quality, won't because printing produces gas harmful to health. Expanded manufacturing company providing durable laser printer toner, digital copier toner, color toner, etc. , various models, size, material, welcomed the purchase. Toner polymerization toner technology has been around for years: - In 1972 the first patent (polymerization toner Meaning: open letters or public documents) Right. — In the 70 s and 80 s wide ( 广泛) To improve. — In 1993 the first commercial monochrome toners. — In 1998 the first commercial color toner. The process flow of polymerization toner ( liú chéng) :( Resin monomer, pigment, dispersing agent, other reagent) →( Ultrasonic dispersion) →( Water, dispersing agent) →( Whisk together) →( Aggregation) →( Washing) →( Filtration separation) →( Dry) →( Post-processing) →( The finished product) 。 For nearly a year, scientists to 60 voluntary participants physical condition has carried on the track record, the participants of studying these often contact toner in daily work conditions, physical condition exactly what will happen. In addition, scientists also regularly to medical examination, the participants periodically office all kinds of fine particles in the air concentration, floats and microorganism ( 微 生物) And so on. Research costs are too high. To do this, scientists have suggested that a good way to test is often office air, and to have one of these symptoms for a medical. The main components of the toner is not carbon, and most is made up of resin and carbon black, electric charge and magnetic powder ( 磁粉) And so on. Toner by high temperature melting into the paper fiber, resin was oxidized into gas with a pungent odor, this is what we call 'ozone. This gas is only one good, is to protect the earth, reduce the solar radiation ( 辐射) The hazards. Itself is no good to human body, can cause stimulation to the human body mucous membrane, easy to increase the incidence of asthma or nose allergy, or even the phenomenon such as dizziness, vomiting. On the production of office equipment (run, shèbèi) Few companies of their products in daily work under the condition of all kinds of testing. In general, the ink in the drum of the toner used except polyester containing carbon black, iron oxide, and also contains many metal powder, such as nickel, cobalt, gǔ) Mercury and harmful to human body, different content of different products. In addition, the toner contains known carcinogens, such as benzene, formaldehyde and styrene. Color print cartridge is ruling, such as bis oxide ( 三丁基锡) The parts per million grams can endanger human hormone secretion, resulting in a decline in men's sperm count and female infertility. Germany has was banned in 2003 in the shipbuilding industry using the material.
