Embodiment 1
[0074] Purification of polyether ether ketone resin prepared with diphenyl sulfone as solvent.
[0075] Take 25 kg of polyetheretherketone containing diphenyl sulfone and inorganic salts, grind it, put it into the washing kettle, and start stirring at a speed of 200 r / min. Add 200kg of acetone to the solvent tank, turn on the heating, half an hour later, the acetone is completely soaked in the polymer and starts to flow back into the solvent tank through the siphon, at this time, pure acetone vapor continuously flows into the washing tank, and at the same time, there is diphenyl The acetone in the sulfone was refluxed to the solvent kettle by siphon action, and maintained in this state for 9 hours, and the content of diphenyl sulfone was tested every 90 minutes in the middle, and then the vacuum pump was turned on to extract the acetone in the washing kettle into the solvent kettle, and the solvent kettle Take out the acetone and replace it with deionized water. Continue washi...
Embodiment 2
[0079] Purification of Polyetheretherketone Ketone Resin Using Diphenylsulfone as Solvent
[0080] Take 25 kg of polyether ether ketone ketone containing diphenyl sulfone and inorganic salts, pulverize it, put it into the washing tank, and start stirring at a speed of 200 r / min. Add 200kg of ethanol to the solvent kettle and turn on the heating. After 40 minutes, the ethanol is completely soaked in the polymer and starts to flow back into the solvent kettle through the siphon. The ethanol is refluxed to the solvent kettle through siphon action, and maintained in this state for 12 hours, and the content of diphenyl sulfone is tested every 2 hours in the middle, and then the vacuum pump is turned on to pump out all the ethanol into the solvent kettle, and the ethanol in the solvent kettle is extracted and replaced with Ionized water, continue to wash in the same way, and start to reflux after about 1 hour, and after maintaining the reflux state for 10 hours, pump out the deioniz...
Embodiment 3
[0084] Purification of polyether ether ketone resin prepared with sulfolane as solvent.
[0085] Take 25 kg of polyether ether ketone containing sulfolane solvent and inorganic salts, grind it, add it into the washing tank, and start stirring at a speed of 200 r / min. Add 200kg of deionized water to the solvent kettle and turn on the heating. After 1 hour, the deionized water is completely soaked in the polymer and starts to flow back into the solvent kettle through the siphon. At this time, pure deionized water continuously flows into the washing kettle At the same time, the deionized water with solvent and inorganic salt is refluxed to the solvent tank through siphon action, and it is maintained in this state for 9 hours, and the content of solvent and inorganic salt is tested every 90 minutes in the middle, and then the vacuum pump pumps out the deionized water in the washing tank water, and the purified polyetheretherketone was sucked out by vacuum suction, dried to constan...
