Therefore, the residual internal stress in the product is high, and it should be treated after the post. 3) PPO is an amorphous material. The rheological properties of the material in the melting state are close to the Newton fluid, but the greater the degree of deviation from the Newton fluid as the temperature rises. 4) the viscosity of PPO melt is large, so the temperature should be improved and the injection pressure should be improved to improve the filling ability. 5) the reuse of PPO can be reused, and it is used repeatedly 3 times, and its performance is not significantly reduced. 6) the PPO melt should be molded by a screw injection molding machine. The nozzle has a good straight through, and the aperture is 3-6mm 7) in PPO injection molding, high pressure and high speed injection should be taken, and the time of pressure protection and cooling should not be too long. 8) the sprue mold should adopt large taper?or?by pulling hook, sprue to stub as well. 9) the gate should be directly, fanned?or?flat, and the diameter should be increased properly when the needle gate is used, and the structure of the hot runner can be used for the long cast. 10) the forming shrinkage rate of PPO is small, which is generally 0.2% 1 0.7%, so the product has good size stability. 11) poor fluidity, which is similar to Newton fluid, the viscosity is more sensitive to the temperature, and the thickness of the product is generally above 0.8 mm. It is very easy to decompose, and the corrosion gas is produced when decomposing. The molding temperature should be strictly controlled. The mold should be heated and the flow resistance of the feed system should be small. 12) water polyphenylene ether's low rate of about 0.06%, but the trace moisture can lead to smooth silver and other phenomena appear on the surface of the product, it is best for the drying process, the temperature can not be higher than 150 degrees, otherwise the color will change. 13) the molding temperature of polyphenylene ether is 280-330 degrees, and the molding temperature of the modified polyphenylene ether is 260-285 degrees. PPO plastic raw material injection process melting temperature: 270-290 C application area
