前言由于PP是一种非极性高聚物,作为复合管内衬材料在输送介质的过程中,无疑是一大优点——良好的化学稳定性及耐磨性。但是它又给PP—FRP界面的粘接带来了困难。因此,为进一步提高PP与FRP的粘接能力,在粘接前应首先对PP表面进行必要 Preface Since PP is a non-polar polymer, as a composite pipe lining material in the process of transporting media, is undoubtedly a big advantage - good chemical stability and wear resistance. However, it poses difficulties in bonding the PP-FRP interface. Therefore, in order to further improve the adhesion between PP and FRP, the PP surface should be firstly bonded before bonding
