Description

A kind of chemical synthesis process of colored carbon powder
Technical field:
The present invention relates to a kind of chemical synthesis process of colored carbon powder.
Background technology:
The tradition of employing warm-up mill and analog contacts the fusion fixation method and is widely used in fixing toner.Provide have warm-up mill and a pressure roll contact the used fixing device of fusion fixation method.When the recording paper that has ink powder image passes pressure contact sections (folder portion) between warm-up mill and the pressure roll, this fixing device with ink powder image fusion and photographic fixing on recording paper.
So far, at the recording unit that is used for obtaining by electrophotographic system coloured image, basic three primary colors develop corresponding to image information separately, and successively the ink powder image that produces of stack to obtain coloured image.At present, the color toner that uses on color copy machine, color printer, colour facsimile apparatus and the chromatic printing machine polymeric toner of chemosynthesis normally.This chemical polymerization ink powder is mainly made by other auxiliary materials such as emulsion, pigment and crosslinking chemicals.Its preparation method is earlier other auxiliary materials such as emulsion, pigment and crosslinking chemical to be put together, through evenly stirring, makes granular material, then, granular material is cleaned the buoyant on the flush away granular material.Afterwards, the granular material through cleaning is carried out dried.At last, in the granular material of treated mistake, add auxiliary materials such as silicon dioxide, and evenly mix and make.Its shortcoming is: after polyreaction, owing between the molecule bonding agglomerating trend is arranged, molecule can be embraced into bulk, can bond together again between bulk and the bulk, become big bulk body, cause the granular material volume behind the chemical polymerization excessive, the size-grade distribution of ink powder is wide, makes useless powder rate height.
Summary of the invention:
The objective of the invention is in order to overcome the shortcoming of above-mentioned prior art, provide a kind of yield rate the high and uniform colored carbon powder chemical synthesis process of pulverizing.
For achieving the above object, technical scheme provided by the invention is: a kind of chemical synthesis process of colored carbon powder is characterized in that may further comprise the steps:

D. to the granular material sizing screening, remove particle diameter greater than 10 microns, less than 4 microns particles;
E. putting in the mixer, and add external additive,, make color toner through evenly mixing through garbled granular material.
Described adjuvant is one or more any mixing in silicon dioxide, hexamethyl dichlorosilane or the dimethyldichlorosilane.
Used crosslinking chemical is a high molecular polymer.
After adopting technique scheme, after the abundant polymerization of material, utilize magnetic resonance that bulky grain is ground into fine grained, thereby make most of particle all several between 4 microns～10 microns, reduce useless powder rate.

Because intermolecular acting force, each molecule in the mixed liquor is not that the form with individual molecule exists in the liquid, but that many molecules are embraced is agglomerating.This has just caused in the mixed liquor after polyreaction and has had the bigger bulk body of a large amount of volumes, and this bulk body particle diameter is all greater than 10 microns.
The base unit of material is an atom, says atomic model in the chemistry, and promptly electronics is around the atomic nucleus rotation.The electronics of these rotations has formed ring current, and ring current has just produced magnetic field.From this angle, any material all is magnetic, and only owing to its internal electron direction of motion confusion, each magnetic field intensity is cancelled each other, so externally do not show magnetic (except the magnet).When a magnet near will be magnetized object the time, electronics in the object that is magnetized is subjected to the magnetic field that magnet produces Lorentz force effect and do the motion of rule, produce magnetic moment, no longer cancel each other in the electric current formed magnetic field that the electronics of these regular motion forms, so externally show magnetic, promptly be magnetized, magnetic moment makes molecule in the fluid, atom, rearranges with electronics.Because the liquid electronic energy keeps higher spin states, this phenomenon is referred to as the magnetic fluid memory effect.
But have again in the environment of alternating magnetic field at existing static magnetic field, bulk body in the mixed liquor is subjected to the effect of static magnetic field and rearranges being tauted, alternating magnetic field does not stop to carry out the variation of position or magnetic field intensity simultaneously, reach the resonant frequency of the big bulk body (particle diameter is greater than 10 microns) of volume when change frequency, when not reaching the resonant frequency of other bulk body again simultaneously, the big bulk body (particle diameter is greater than 10 microns) of volume will be smashed littler particle by resonance, thereby make more bulk body particle size fall into 4～10 microns these intervals, improve the extraction ratio of ink powder, reduce the generation of useless powder.
