Problems solved by technology

However, due to improper installation, transportation or storage of toner cartridges and toner cartridges, the residual toner is easily affected by the environment, with moisture, impurities, etc., and cannot be used directly. It is a great waste to discard this part of toner. Therefore, How to reproduce the recovered toner so that it can be used is a difficult problem currently being explored
[0003] At the same time, those skilled in the art know that when the printer works for a long time, if the environment where the printer is located is not ventilated in time, there will be a certain smell when printing, which is harmful to the human body, or there is more toner in the air. It will cause damage to the user's respiratory system, therefore, how to remind the user to ventilate the environment where the printer is located is an urgent matter to be solved

Abstract

The invention discloses a method for recovering black carbon powder to be modified into colored carbon powder. The method comprises the following steps: step one, a coloring agent, an external additive and a modifier are taken to be subjected to ultramicro-pulverization treatment; step two, impurities in the black carbon powder are filtered and removed, the black carbon powder and the coloring agent are dissolved in water, and first-time ultrasound treatment is conducted; step three, the modifier is added, and second-time ultrasound treatment is conducted; step four, the carbon powder is dried; step five, the modified carbon powder is extruded; and step six, the modified carbon powder is vibrated by ultrasonic vibrating equipment and then also subjected to ultramicro-pulverization, carbonpowder with the particle size being 5 microns or below is obtained, the external additive is added, and thus the colored carbon powder is obtained, wherein the external additive is any one or more offerroferric oxide, nickel powder, iron powder and calcium iron oxide. According to the colored carbon powder, printing pages are all normal during printing, dirty edges are avoided, printing is smooth, inkjet is uniform, pattern colors are consistent, and the damage influence on a printer is avoided.

Description

technical field [0001] The invention belongs to the technical field of printer consumables, and relates to a method for recycling black carbon powder and improving it into colored carbon powder. Background technique [0002] Printer (Printer) is one of the output devices of computer, with the quickening of life and the widespread use of electronic products. Printers are becoming an essential item in consumers' work and life. With the use of printers, the demand for printing consumables is also increasing. Most of the toner is composed of resin and carbon black, charging agent, magnetic powder and so on. The toner is melted into the paper fiber by high temperature, so that the output content can be displayed. Toner is one of the important consumables. In the recycling of printer consumables, in order to protect the environment and avoid material waste, toner must be classified according to color and category. However, due to improper installation, transportation or stora...
