产品采用韩 PE材质，而pe材质浮体、浮筒、浮球、浮漂、浮标采用滚塑工艺次成型-滚塑成型又称旋塑、旋转成型、旋转模塑、旋转铸塑、回转成型等，英文表达为ROTATIONAL MOULDING 。滚塑成型工艺是先将塑料原料加入模具中，然后模具沿两垂直轴不断旋转并使之加热，模内的塑料原料在重力和 的作用下，逐渐均匀地涂布、熔融粘附于模腔的整个表面上，成型为所需要的形状，再经冷却定型而成制品. 使用可达20年以上， 高。具有、和的 长江南京以下深水航道建设工程指挥部召开本次会议旨在深入落实家“依托长江黄金水道，建设长江经济带”发展战略，进一步多方合作，集思广益，共同做好南京以下深水航道及航道建筑物保护工作。

Floating is located at the front of a certain water area before the intake to intercept the floating type of fouling equipment in the water. In rivers with more floating debris, if only a barrier is set up, a large amount of debris will accumulate in front of the barrier, and if the cleaning is not timely, the barrier hole will be blocked and the water diversion will be affected. In the front of the trash rack, the blocking and bleaching platoon is used together, and the effect is good. The floating body is used in a variety of ways, the use of different environments, different ways of force, resulting in different shapes of floating products.
The flow pattern of the hydropower station should be stable and not too complicated. The downcut, vortex and strong turbulence are the main factors affecting the effect of pollutant interception and must be avoided. As shown in Fig. 4, the effect of a power station&＃39;s sewage interception drainage during flood season can be seen from the diagram, a large amount of sewage with the flow around the sewage interception drainage, gathered behind the sewage interception drainage, the effect of sewage interception is not satisfactory. The main reason for this problem is that the cofferdam before sewage interception and drainage was not dismantled according to the design requirements, resulting in local water flow d***rder and undercutting before sewage interception and drainage, resulting in the sewage with rapid flow around the bottom of the sewage interception and drainage. It can be seen that steady flow pattern and small velocity are crucial to the pollution control effect.
