PVC 型材的特點(diǎn)及發(fā)展現(xiàn)狀與前景并從聚氯乙烯管材生產(chǎn)工藝著手，選擇普遍使用的雙螺桿擠出成型的成型方法生產(chǎn)聚氯乙烯管材，通過配方選擇、物料衡算、熱量衡算、設(shè)備選型、工藝參數(shù)控制等過程對整個工藝流程作了較為詳 盡的闡述。另外指出硬質(zhì) PVC 管材成熟的生產(chǎn)工藝路線，并從低成本、高性能、功能應(yīng)用等各方面考慮設(shè)計了較為合理的硬質(zhì) PVC 管材生產(chǎn)配方和留有發(fā)展?jié)摿Φ纳a(chǎn)設(shè)備，計算其生產(chǎn)車間所需的各種生產(chǎn)設(shè)備和總投資成本，繪制出工藝流程圖和生產(chǎn)車間設(shè)備平面布置圖，對實(shí)際投資建設(shè)硬質(zhì) PVC 管材產(chǎn)車間的各個方面具有積極的指導(dǎo)作用。 關(guān)鍵詞 ：硬質(zhì)
