Embodiment 1

[0015] Mix 60 parts by weight of N-methylpyrrolidone and 40 parts by weight of methyl ethyl ketone evenly to form a release agent, put the old organic photoconductive drum into the airtight release agent and soak for 0.5 hour, and the release agent is in a circulating state in the stirring device; 40KHz ultrasonic rough cleaning in normal temperature pure water for 10 minutes; 13m 3 / min air intake nitrogen stirring pure water rinsing for 8 minutes; then put the organic photoconductive drum into pure water for 40KHz ultrasonic cleaning for 10 minutes; 13m 3 Rinse with pure water for 10 minutes with nitrogen gas at an intake air volume per minute; finally, place the drum base on a tray stand and dry it under vacuum at 45°C for 6 hours.

[0016] After drying, use a stereo microscope to observe the surface of the aluminum base, no residual film, no damage; use a surface roughness meter to test the surface roughness, the roughness is not significantly different from the brand new ...

Embodiment 2

[0018] Mix 70 parts by weight of N-methylpyrrolidone and 30 parts by weight of cyclohexanone to make a release agent, put the old organic photoconductive drum into the airtight release agent and soak for 0.5 hours, and the release agent is circulating in the stirring device State; 40KHz ultrasonic rough cleaning in normal temperature pure water for 10 minutes; 13m 3 / min air intake nitrogen stirring pure water rinsing for 8 minutes; then put the organic photoconductive drum into pure water for 40KHz ultrasonic cleaning for 10 minutes; 13m 3 Rinse with pure water for 10 minutes with nitrogen gas at an intake air volume per minute; finally, place the drum base on a tray stand and dry it under vacuum at 45°C for 6 hours.

[0019] After drying, use a stereo microscope to observe the surface of the aluminum base, no residual film, no damage; use a surface roughness meter to test the surface roughness, the roughness is not significantly different from the brand new aluminum base, in...

Abstract

The invention provides a novel remover. By using the remover and a cleaning method in the invention, thin polymer film adhered on the surface of the organic photoconductive drum can be effectively removed in a short time and the organic photoconductive drum drum-based aluminum is avoided from being corroded. In addition, the film removing method has simple operation, small time consumption and good film removing effect, and the aluminum base after being removed film can be used in reproducing of the organic photoconductive drums.

Description

technical field [0001] The invention belongs to a film-removing treatment method for surface materials of aluminum profiles, in particular to a method for removing polymer films on the surface of old organic photoconductive drums. Background technique [0002] The core part of toner cartridges for laser printers is the organic photoconductive drum, which will be scrapped due to mechanical wear and photoelectric fatigue after several cycles of use. Directly discarding scrapped organic photoconductive drums will cause waste of resources and environmental pollution. Therefore, it is necessary to remove the polymer film on the drum base of the old organic photoconductive drum to regenerate the drum base. At present, there is no mature and effective stripping regeneration technology at home and abroad. Tianjin Photocopying Technology Research Institute once conducted research on organic photoconductive drums of photocopiers, but it used amine alkaline solution to remove the film...
