苯二甲酐是一种很难用普通容器进行运输的化学剂。这种化学剂可用作制造水龙带和快艇壳体材料的添加剂,它能提高材质的强度和韧性,凝固点在137.7℃。通常,在凝固点以上苯二甲酐是液态,低于这个温度就立即变成固态,因此使用通用罐车运输,很难使苯二甲酐保持液态,从而造成装卸和运输困难。为了解决这一问题,美国罐车联盟研制成功一种用于运输苯二甲酐的新型专用罐车,其特点是: (1) 卸货装置位于车顶,加大了虹吸管尺寸,从而提高了安全性能; (2) 罐体周围安装19根加热管,可以迅
Phthalic anhydride is a chemical that is difficult to transport in common containers. This chemical can be used as an additive to hose and boat shell materials to increase the strength and toughness of the material with a freezing point of 137.7 ° C. Typically, the phthalic anhydride is liquid above the freezing point, and immediately below this temperature it becomes solid, making it difficult to maintain the phthalic anhydride in a liquid state using a common tanker truck, resulting in difficulties in handling and transportation. In order to solve this problem, the US Tanker Alliance has successfully developed a new type of special tankers for the transportation of phthalic anhydride. Its features are: (1) the unloading device is located on the roof of the vehicle and the size of the siphon is enlarged so as to improve the safety performance; (2) 19 heating tubes installed around the tank, you can quickly
