Description
本发明涉及一种能抗磨损、抗气蚀、抗腐蚀、抗结垢的聚氨酯、玻璃钢复合管道。The invention relates to a polyurethane and glass-steel composite pipeline capable of resisting abrasion, cavitation, corrosion and fouling.
现在火电厂对燃尽后煤的灰渣用管道进行长距离的水力输出，必须要解决受灰渣冲蚀所引起的管道磨损问题和高钙煤灰的灰渣结垢所引起的管道畅通问题，虽然耐磨合金铸钢管道能基本解决磨损问题，但其造价高、份量重；其灰渣结垢问题用加盐酸、阻垢剂或使灰渣水磁化等方法，但费用高，效果仍不理想。水电厂的泄洪管道常受到气蚀困扰，尚未找到有效的解决办法。Now thermal power plants use pipes for long-distance hydraulic output of burnt coal ash, and must solve the problem of pipeline wear caused by ash erosion and the smooth flow of pipelines caused by ash scaling of high-calcium coal ash Although the wear-resistant alloy cast steel pipeline can basically solve the wear problem, its cost is high and its weight is heavy; the method of adding hydrochloric acid, antiscalant or magnetizing the ash and slag water for its ash and slag scaling problem is high, but the effect is still not ideal. The flood discharge pipelines of hydropower plants are often troubled by cavitation, and no effective solution has been found.
本发明的目的在于提供一种耐磨性好、抗结垢、抗气蚀、又较经济的聚氨酯、玻璃钢复合管道。The object of the present invention is to provide a polyurethane and glass fiber reinforced plastic composite pipe with good wear resistance, anti-scaling, anti-cavitation and relatively economical.
本发明的任务是这样实现的：管道具有外壳和内衬，外壳是玻璃钢，内衬是粘合在外壳内壁上的聚氨酯弹性体。The task of the present invention is achieved in that the pipeline has an outer shell and an inner lining, the outer shell is made of fiberglass, and the inner liner is a polyurethane elastomer bonded on the inner wall of the outer shell.
上述复合管道的外壳是合成树脂与玻璃纤维或玻璃布的复合材料，以承受管道压力；内衬聚氨酯弹性体具有极好的耐磨性和抗气蚀性，因无极性，化学稳定性好，表面张力小，因此抗结垢性也好，复合后的管道重量轻、工程造价低，安装维护费用低，适用作需抗磨损、抗气蚀、抗腐蚀和抗结垢的水力管道。The outer shell of the above-mentioned composite pipe is a composite material of synthetic resin and glass fiber or glass cloth to withstand the pressure of the pipe; the inner liner polyurethane elastomer has excellent wear resistance and cavitation resistance, and has good chemical stability due to non-polarity. The surface tension is small, so the scaling resistance is also good. The composite pipeline is light in weight, low in engineering cost, and low in installation and maintenance costs. It is suitable for hydraulic pipelines that require anti-wear, anti-cavitation, anti-corrosion and anti-fouling.
以下用附图结合实施例，对本发明的具体结构再作进一步的说明：Below in conjunction with embodiment with accompanying drawing, concrete structure of the present invention is described further:
图1为本发明提供的聚氨酯、玻璃钢复合管道的主视图。Fig. 1 is the front view of the polyurethane and FRP composite pipe provided by the present invention.
图2为图1结构的右视图。Fig. 2 is a right view of the structure in Fig. 1 .
如图所示，管道外壳(1)是以合成树脂为基本材料，与玻璃纤维或玻璃布等增强材料复合为轻质高强的玻璃钢，其中合成树脂可为不饱和聚脂树脂、环氧树脂或乙烯基脂树脂等。管道内衬(2)是聚氨酯弹性体用特种粘合剂粘合在玻璃钢外壳的内壁上，形成复合管道。As shown in the figure, the pipe shell (1) is made of synthetic resin as the basic material, which is composited with reinforcing materials such as glass fiber or glass cloth to form light and high-strength FRP, wherein the synthetic resin can be unsaturated polyester resin, epoxy resin or Vinyl resin, etc. The pipe liner (2) is made of polyurethane elastomer bonded on the inner wall of the FRP shell with a special adhesive to form a composite pipe.
