Before washing.
Both A & B have been soaked in the following lotions, but they don't seem to work very well. The black dirt inside the ceramic tube and the adhesive between the rear PEEK plastic and the ceramic tube have not been removed.

ACHM04-A / 72 hrs up + ultrasonic shock
-
ACHM04-H1 / 72 hrs up + Ultrasonic shock
-
PTC13 / 72 hrs up + Ultrasonic shock
The most original appearance of the sample. A small piece of plastic is broken inside the ceramic tube. If it is removed mechanically, it will easily cause the ceramic tube to break (C&D).

Sample E was observed under a microscope.
The surface is covered with glue, and a section of PEEK plastic tube remains in the tube, and a circle of glue remains.
-
Test sample E with hardening ink cleaner ACHM01-G. It is found that cleaning at 130°C can effectively remove the surface adhesive, and PEEK plastic tube.
After washing for 5 minutes. The surface adhesive and PEEK plastic tubes have come off. But the black carbon black part still cannot be removed cleanly.
-
Repeat the test, take sample A, and soak it in ACHM01-G hardening ink cleaning agent at 130°C.
It is found that after soaking for 10 minutes, the PEEK plastic tube can be easily pulled out with a nickel.
-
After the PEEK plastic tube is pulled out, continue to soak in 130°C hardening ink cleaning agent ACHM01-G until the internal EPOXY glue is completely dissolved. Take it out and rinse it with clean water. It is found that the residual glue inside the ceramic tube has been cleaned. But the black carbon black part still cannot be removed cleanly.
