研究钢闸门支承滑道材料的选用，经历了层压胶木、塑料滑道、镶嵌型复合材料，属基复合材料、ＴＳ－７０钉板型铜塑复台材料５个阶段，ＴＳ－７０钉板型铜塑复合材料的研制成功，是迄今为止在这一领域里取制的最好成果，并获得了国家专利。它的优点是：具有极大的承载力，剪不坏的结构，弹性调节终身不竭的自润滑功能，非常小而稳定的摩擦系数。
In this paper, the selection of steel gate supporting chute material has been studied. It has gone through five stages of laminated bakelite, plastic chute, inlaid composite material, metal matrix composite material, TS-70 nail plate type copper- Type of copper-plastic composite materials successfully developed, is by far the best in this area, and won the national patent. Its advantages are: a great bearing capacity, not bad cut structure, flexible adjustment of life-long self-lubricating function, a very small and stable coefficient of friction.
