弹性聚氨酯密封止水材料在我省水利工程中的应用

Appliance of the Elastic Polyurethane Sealing Material in the Hydraulic Engineering in Our Province

弹性聚氨酯是一种介于一般橡胶与塑料之间的高分子聚合材料．它既具有塑料的高强度，又具有橡胶的高弹性，且有优良的耐油、耐水、耐磨损、耐辐射特性，施工简便．该材料已在省内外许多水利工程的止水伸缩缝和钢筋砼裂缝修补中得到应用，取得了理想的效果，有着广泛推广应用的前景．

The elastic polyurethane is a kind of high polymeric material between common rubber and plastic,It not only has the high strength feature of plastic and the high elasticity of rubber,but also has the good characteristics such as oil-resistance,water-resistance,anti-friction,radiation-resistance.Constr-uction is simple.This kind material was used in repairing the sealing expansion joints and the reinforced concrete cracks in a large number of the hydraulic eng-ineerings inside or outside our province,and the desired effection has been achieveel,It has a wide prospect in popularizing appliance.
