Embodiment
[0009] 1. Sieve the collected 30 tons of recycled carbon powder to remove mechanical impurities mixed in it.
[0010] 2. Put a batch of 5 tons into a large mixer and mix for 5-10 minutes to make the quality consistent.
[0011] 3. Take three batches of samples from the mixed carbon powder, and use an elemental analyzer or combustion method to analyze the content of the magnetic powder to obtain the content and adjust it
[0012]
[0013] The print quality is as follows:
[0014] the batch
[0015] From the above results, it can be seen that the recovered powder is processed according to the above procedures, and the magnetic powder is analyzed and uniformly prepared to obtain qualified products with consistent quality and stable quality.

The invention relates to a method for recycling black printer magnetic toner; firstly, the recovered black printer toner is sieved, and secondly, no less than 1 ton of recovered powder is mixed in a mixer to make it uniform, Then carry out the composition analysis of the magnetic material, determine the percentage content of the magnetic powder material, and then adjust the required components so that the adjusted formula is consistent with the formula for producing qualified products, mix, extrude, crush and classify. , plus additional processes to produce qualified products that meet the requirements. The beneficial effect of the invention is that the recovered carbon powder can be effectively used to regenerate qualified carbon powder, which greatly saves resources.
Description
technical field [0001] The invention belongs to a method for reusing recycled materials, in particular to a method for reusing black magnetic toner of printers. Background technique [0002] Recycling printer toner for reuse has higher profit returns, but because of its variety and inconsistent components, it is very difficult to recycle and reuse it to produce qualified toner with consistent and stable quality. The production of printer toner mainly consists of 4 to 5 components, of which the resin content is 40-70%, and the magnetic powder content accounts for 30-60%, which shows the main function of magnetic powder. Contents of the invention [0003] The object of the present invention is to provide a method for reusing the black magnetic toner of a printer that can ensure qualified and stable product quality. [0004] In order to achieve the above object, the method adopted in the present invention is: [0005] A method for recycling black printer magnetic toner; fir...
