An anti-combustible polyurethane insulation coating was produced by incorporating epoxy-acrylic resin 、 chlorinated paraffin wax and antimony trioxide into the system. 以环氧改性丙烯酸树脂为基料,氯化石蜡和Sb2O3为阻燃改性剂,制得了阻燃型丙烯酸聚氨酯绝缘涂料。
A floating/ wax cleaning transportation process for waxy crude oil is proposed for the on-line oil pipeline with the throughput lower than design throughput in order to fully use the insulation effect of wax deposit to adjust oil and electricity consumption proportion. 对于在役且输油量低于设计输量的含蜡输油管道,为充分利用结蜡层的保温效果来调节油电消耗的比例,提出了含蜡原油浮动清管输送工艺。
