Forming method of carbon powder particle

Abstract

The invention aims at providing a resin particle forming formula capable of enabling resin to be well micronized and a product manufacture method. The product manufacture method comprises the following steps: (1), dissolving a high-pressure fluid and a pressure deformation material through contact to obtain a dissolved state mixture with a viscosity of below 100mPa*s in a static mixer; and (2), spraying the dissolved state mixture by using a nozzle. The pressure deformation material is polyester resin, phenolic resin, polystyrene resin or polylactic resin. The high-pressure fluid is carbon monoxide, carbon dioxide, a mixture of air and nitrogen, and one or a mixture of more of insert gases, ethane and ammonia gas. The high-pressure fluid is enabled to be in contact with the pressure deformation material, and a pressure generated by the high-pressure fluid promotes the pressure deformation material to be plasticized, and thus the high-pressure fluid and the pressure deformation material are homogenized and mixed, the viscosity is reduced, and better resin micronization effect is obtained.

Description

technical field [0001] The invention relates to a method for forming carbon powder particles. Background technique [0002] The composition of the resin and its additives is melted and kneaded, solidified and crushed to make carbon powder in the form of particles. When the carbon powder is manufactured by this method, some particles with large particle sizes generated during the crushing are not easy to be removed, making it difficult to remove. The problem of poor chargeability and fixation performance. [0003] In order to solve this problem, in the toner manufacturing process in recent years, the colored resin solution is generally emulsified and dispersed to form an emulsion with non-water-soluble organic solvents such as polyester resin and colorant, and then mixed with the organic solvent. After being discharged, colored resin particles are formed, and carbon powder particles can be obtained after agglomeration. This method will discharge a large amount of organi...

Problems solved by technology

[0004] However, when high-pressure fluids containing dissolved resin and carbon dioxide are mixed, a uniform mixture cannot be obtained because the viscosity of the two is poor. If the viscosity of the mixture cannot be lowered, as a result, when the mixture is sprayed from the nozzle, the mixture The particles will be solidified before forming, and the resin cannot be finely granulated
