BAM 451是英国Beardow ＆ Adams公司专为生产海底通信光缆配制的热熔融粘合剂.英国STC海底系统公司采用这种粘合剂,把海底光缆12mm厚的高密度聚乙烯护套与高强度钢线加强件隔离开来.把该粘合剂填入所有空隙,在护套和加强件的表面形成可靠的粘合,既可防止高负荷下的受压,又能起防潮作用.这种热熔融粘合剂的问世使STC公司解决了一大难题,即确保缆内没有任何移动.粘合质量极为重要,因为在敷设或打捞作业过程中,当光缆承受8吨张力时,不允许内层出现移动现象.
BAM 451 is a hot melt adhesive specially formulated by Beardow & Adams, UK for the production of optical fiber cables for undersea communications. STC Seabed Systems UK uses this adhesive to bond high-density polyethylene sheathed 12mm thick submarine cables to high strength steel The line stiffener is isolated by filling the adhesive into all voids and forming a reliable bond between the jacket and the stiffener surface, both against compression under high loads and against dampness. The advent of fusion adhesives has caused STC to solve one of the major challenges of ensuring that there is no movement in the cable.The quality of the bond is extremely important because the inner layer is not allowed when the cable is subjected to 8 tons of tension during lay-up or salvage operations Appear mobile phenomenon.
