在水利电力和工业与民用建筑工程中,用以输送水、油、气的管道目前常见的多是陶瓷、金属、水泥或塑料制成。最近美国得克萨斯州立大学教授希尔贝发明一种用海水制造的管子,开始用于管道工程建设中。其制造方法是; 用铁丝网卷成一定直径和长度的园筒,在园筒中间放置一个铅管,接上10～100伏特的电压后,把过套装置放人海水中。几天后,在铁丝网的园筒上就会自动吸附一种白色物质。当白色物质达到一定厚度时,抽出铅管,就成为一根结构紧密,不漏水,不漏气的管子,即可直接供工程建设之用。经试验证明,在铁丝网上吸附的那种白色物质,系氢氧化镁和碳酸钙。这两种物质都是良好的建筑材
In water conservancy and electric power and industrial and civil construction projects, the pipes used to transport water, oil, and gas are currently made mostly of ceramic, metal, cement, or plastic. Heilbeier, a professor at Texas State University in the United States, recently invented a pipe made of seawater that was used in the construction of pipeline projects. The method of manufacture is: using a barbed wire to form a cylinder of a certain diameter and length, placing a lead pipe in the middle of the cylinder, and then applying a voltage of 10 to 100 volts to release the over-fitting device into the seawater. A few days later, a white substance will be automatically adsorbed on the wire mesh cylinder. When the white substance reaches a certain thickness, the lead pipe is drawn out, and it becomes a tightly-structured, water-tight, leak-free pipe, which can be directly used for the construction of the project. Tests have shown that the white substance absorbed on the wire mesh is magnesium hydroxide and calcium carbonate. Both of these substances are good building materials
