在里约热内卢的瓜纳巴拉湾,几十年来,无数废弃的船只被遗留在这里,任由风浪侵蚀。 这些船并没有真正"死"去,它们正在以一种微观的方式"转世"。 图源: avozdonavegante 故事要从上世纪中叶说起,一种被称为玻璃纤维增强塑料(GRP)的材料横空出世。它由两部分组成:作为骨架的微细玻璃纤维和作为填充物的树脂(通 常是聚酯或环氧树脂)。 当工人们打磨船体准备重新喷漆时,或者当船体在水中自然磨损时,含有玻璃纤维碎屑和醇酸树脂(Alkyd Resins)的粉尘便像雪花一样飘落在水面上。 双壳类软体动物它们是海洋中的"吸尘器",为了获取营养,它们必须不停地过滤海水。一只成年牡蛎每天可以过滤近200升水。它们通过鳃上的纤毛捕捉 水中的颗粒物。这些生物并不能区分浮游植物和微小的玻璃纤维碎片,一概并收。 玻璃纤维增强塑料 图源:hrfibreglass 这种组合轻便、坚固且耐腐蚀,迅速取代了木材,成为造船业的宠儿。在巴西,随着休闲航海和渔业的兴起,成千上万艘玻璃钢船下水。人们当时只看到 了它的优点:它不像木头那样会腐烂,也不像钢铁那样容易生锈。然而,这种材料的"耐用性"在几十年后变成了一个灾难。 到了21世纪,第一批 ...
