PP-B铜塑管件生产工艺的研究

Study on the Production Technology of PP-B Copper Plastic Pipe

采用注塑成型法生产出嵌段共聚聚丙烯(PP-B)铜塑管件,讨论了塑化温度、注塑压力、注塑速度等工艺条件对PP-B铜塑管件质量的影响。结果表明,当塑化温度200℃、注塑压力60 MPa、注塑速度75 m/s、注塑保压时间20 s时,PP-B铜塑管件的质量较理想。

With injection molding method, block copolymer PP-B copper pipe was produced. The effects of plastics injection temperature, pressure, injection moulding rate on the quality of PP-B copper pipe was studied. Results indicated that： when the temperature was at 200 ℃, plastic injection molding pressure was 60 Mpa, injection speed was 75 m/s, injection molding holding time was 20 s, PP-B copper pipe had better quality.
