一、前言近四十年以来主要发展起来三种内浮顶,即钢盘式、泡沫塑料内浮顶和铝制内浮顶。由于成本高,施工周期长,安全性差等原因,钢盘式内浮顶的发展趋势已迅速下降;泡沫塑料顶由于静电导出问题难于解决,目前在国外的一些石油公司已停止建造;装配式铝制内浮顶由于安装方便、迅速、安全等优点,近几十年来在世界上获得了迅速的发展,仅美国一个国家就使用了两千多台。
I. INTRODUCTION Three kinds of inner floating roofs have been developed mainly in the past four decades, namely steel disk, foam inner floating roof and aluminum floating roof. Due to the high cost, long construction period, poor safety and other reasons, the development trend of steel floating roof has been rapidly declining; the top of foam plastic is hard to be solved due to the problem of static electricity exporting. At present, some oil companies in foreign countries have stopped construction; Built-in floating roofs have enjoyed rapid growth in the world in recent decades due to their ease of installation, speediness and safety. Only over 2,000 are used in one U.S.-only country.
