铁路油槽车、汽车的油箱以及汽油桶等,都是易燃易爆物品,稍不留意就会发生意外。怎样防爆已成为重要的研究课题。目前虽有一些防爆的方法,但效果都不很理想。前不久,加拿大发明了一种新型防爆装置,它是一种用铝箔做的网。这种网织成蜂窝样,每个蜂窝的六个面上都有小孔,形成互相贯通的许许多多小蜂房,汽油就贮存在这小蜂房里。它的防爆性能就在于把汽油分隔贮存在一个个的小蜂房里,使汽油不能形成一个整体。同时,铝的优良传热性将使受热的 Railway tanker cars, car fuel tanks and gasoline barrels, etc., are flammable and explosive materials, a little careless will happen unexpectedly. How to prevent explosion has become an important research topic. At present, although some methods of explosion-proof, but the effect is not very satisfactory. Not long ago, Canada invented a new explosion-proof device, it is a network made of aluminum foil. The net weaves into a honeycomb, with holes in each of the six sides of each honeycomb, forming many interweaving small hives where petrol is stored in this small hive. Its explosion-proof performance lies in the separate storage of gasoline in a small beehive, so that gasoline can not form a whole. At the same time, the excellent thermal conductivity of aluminum will make it hot
