Abstract

一种具有聚氨酯保护膜层的水利钢制构件是在钢制构件的内表面、外表面或内外表面涂有聚氨酯保护膜层,这种钢制构件具有防水、防腐蚀、防锈蚀、防汽蚀和防磨的功能,可广泛用于管道、水泵、闸门等水利构件。

Description

具有聚氨脂保护膜层的水利钢制构件
本实用新型涉及一种具有聚氨脂保护膜层的水利钢制构件。
目前水利钢制构件由于无聚氨脂保护膜层,所以钢制构件的腐蚀很严重,每年钢制件以0.5-1.5mm的量剥落。
本实用新型的目的是提供一种具有聚氨脂保护膜层的水利钢制构件。
本实用新型的目的是这样实现的:具有聚氨脂保护膜层的水利钢制构件,在钢制构件(1)的内表面、外表面或内外表面涂有聚氨脂保护膜层(2)。
同现有的水利钢制构件比,本实用新型由于涂有聚氨脂保护膜层,所以具有防水、防锈蚀、防磨、防汽蚀、防腐蚀功能,该保护膜层的抗拉强度一般在0.7MPa,抗冲磨强度为174.17hm2/kg,抗磨损率为0.0096kg/hm2,抗汽蚀性能如下:抗压强度为30MPa,总失重量为0.0029克,失重率为3.3×10-5克/分钟,实践证明在高转速(2900转/分)水泵连续运行300小时,保护膜层无变化。
下面结合附图详细叙述本实用新型的技术解决方案。
图1为具有聚氨脂保护膜层的管道结构示意图。
图2为具有聚氨脂保护膜层的水泵结构示意图。
图3为具有聚氨脂保护膜层的闸门结构示意图。
如图1、2、3,具有聚氨脂保护膜层的水利钢制构件可以是管道、水泵、闸门等。
