Polymerization method is a fine chemical toner technology, which includes (suspension polymerization, emulsion polymerization, encapsulated capsules, dispersed polymerization, compression polymerization, chemical crushing.
） The polymerization method is completed in the liquid phase, which can produce toner with low melting temperature, which can meet the requirements of modern technology for energy saving and environmental protection. By adjusting the dosage of dispersant, stirring speed, polymerization time and concentration of solution to control the particle size of toner particles, to achieve uniform composition, good color, high transparency. The toner produced by polymerization method has good grain shape, fine particle size, narrow particle size distribution and better fluidity.
Can meet the high speed, high resolution, color and other modern printing technology requirements.
Polymeric Toner technology has been around for many years:
-The first patent for polymeric Toner appeared in 1972.
-It was widely improved in the 70 and 80.
-The first commercial monochrome toner appeared in 1993.
-The first commercial color toner appeared in 1998.
Process flow of polymeric toner:
(Resin monomer, pigment, dispersant, other reagents) → (ultrasonic dispersion) → (water, dispersant) → (full stirring) → () → (washing) → (filtration separation) → (dry) → (post-processing) → (finished)
Polymeric toner is widely used, because of the high cost, mainly focused on the production of color toner. Polymeric Toner Because of its large investment, the general investment in about hundreds of millions of yuan. Only a small number of large international companies have production capacity: Japan's Canon Company, Konica Company, Minolta Company, the United States Fuji-xerox Company and other enterprises have production capacity, but the demand for color toner is lower than expected, at present, the major companies are not at full capacity production.
