补充资料：高分子减阻剂
| 高分子减阻剂 polymeric drag-reduction additives 具有减小流体流动阻力作用的高分子。在流体输送过程中加入此类高分子，能减少转展阻力，降低能耗。水相输送减阻剂研究开发较早，已研究了大量的水溶性高分子减阻剂，使用量仅几个ppm就可降低50％以上的阻力，有时高达80％。高分子减阻剂的结构及性质是：高分子具有无支链结构，分子量高，溶解性好等。聚环氧乙烷、聚丙烯酰胺是良好的水相减阻剂。油相减阻剂具有重要的实际意义，原油多以管道输送。由于粘度大、摩擦力高，输送中消耗也高，已应用的油相减阻剂有聚异丁烯、氢化聚异戊二烯、无规聚丙烯、丁二烯及苯乙烯的嵌段共聚物、乙烯与乙烯基酯的共聚物聚丙烯酰胺、乙烯和丙烯的共聚物等。如氢化聚异戊二烯，一般用量2～20ppm，即可使流速增加，摩擦损耗降低27％到50％。高分子减阻剂已广泛用于灌溉、泄洪、消防、原油输送等方面。其缺点是价格贵、易降解等。 |
