HP-series colored carbon powder collecting and treating method

Abstract

The invention aims to provide a HP-series colored carbon powder collecting and treating method which is high in recovery rate and good in recovered carbon powder quality. The method comprises the following steps of classifying residual HP-series colored carbon powder according to the models of products in different carbon powder boxes, and centrally collecting the residual HP-series colored carbon powder; analyzing the physical parameter of the residual colored carbon powder in each carbon powder box, and recording data; placing the residual carbon powder into a testing toner cartridge to test, and recording the test data; comparing the test data obtained in the former step with standard data to obtain the physical characteristic of the carbon powder with defects; treating the carbon powder according to the physical characteristic of the carbon powder with the defects; drying the carbon powder, coarsely sieving the carbon powder by using a filter sieve, adding negative conductive particles and a flow aid, mixing, and finely sieving the carbon powder by using a filter sieve; carrying out index test on the treated carbon powder, and recording data; and testing the carbon powder good in index test by using the toner cartridge to ensure that the carbon powder meets the application requirement. The HP-series colored carbon powder collecting and treating method can be applied to the field of residual carbon powder treatment.

Description

technical field [0001] The invention relates to the field of carbon powder recovery, in particular to a method for collecting and processing HP series colored carbon powder. Background technique [0002] At present, for the printer consumables recycling industry, in the process of recycling and processing, the residual toner left in the toner cartridge is basically collected directly, and then transported to incineration or underground landfill. Such a treatment method will seriously damage the ecology. environment and cause serious pollution. For HP color toner, if a new type of collection and processing method can be designed, the above problems can be well solved. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a method for collecting and treating HP series colored toners with high recovery efficiency and good quality of recovered toners. [0004] The technical ...
