Theefoe, the esidual intenal stess in the poduct is high, and it should be teated afte the post.3) PPO is an amophous mateial. The heological popeties of the mateial in the melting state ae close to the Newton fluid, but the geate the degee of deviation fom the Newton fluid as the tempeatue ises.4) the viscosity of PPO melt is lage, so the tempeatue should be impoved and the injection pessue should be impoved to impove the filling ability.5) the euse of PPO can be eused, and it is used epeatedly 3 times, and its pefomance is not significantly educed.6) the PPO melt should be molded by a scew injection molding machine. The nozzle has a good staight though, and the apetue is 3-6mm7) in PPO injection molding, high pessue and high speed injection should be taken, and the time of pessue potection and cooling should not be too long.8) the spue mold should adopt lage tape o by pulling hook, spue to stub as well.9) the gate should be diectly, fanned o flat, and the diamete should be inceased popely when the needle gate is used, and the stuctue of the hot unne can be used fo the long cast.10) the foming shinkage ate of PPO is small, which is geneally 0.2% 1 0.7%, so the poduct has good size stability.11) poo fluidity, which is simila to Newton fluid, the viscosity is moe sensitive to the tempeatue, and the thickness of the poduct is geneally above 0.8 mm. It is vey easy to decompose, and the coosion gas is poduced when decomposing. The molding tempeatue should be stictly contolled. The mold should be heated and the flow esistance of the feed system should be small.12) wate polyphenylene ethe's low ate of about 0.06%, but the tace moistue can lead to smooth silve and othe phenomena appea on the suface of the poduct, it is best fo the dying pocess, the tempeatue can not be highe than 150 degees, othewise the colo will change.13) the molding tempeatue of polyphenylene ethe is 280-330 degees, and the molding tempeatue of the modified polyphenylene ethe is 260-285 degees.
