摘要： The present invention comprises an improved method and apparatus for treating water in heat exchange systems. The present invention automatically and inexpensively provides an effective chemical to process water systems at times and in proportion to the need for water treatment in such systems. When used in evaporative cooling systems, the present invention adds the treatment chemical to the system via the make-up water. The make-up water acquires a substantially constant concentration of treatment chemical as it is passed through a device containing a treatment chemical. The constant concentration of chemical is achieved by dividing the make-up flow into two streams within the device, saturating the smaller of the two streams with chemical, and re-mixing the two streams. The biocide agent used in the preferred embodiment of the invention is prilled elemental iodine.

摘要： This invention relates to a process for the application of organic materials, such as powders, to hot dip or electroplated galvanized metal which provides a finished material with a higher level of corrosion resistance than that obtained from organic coatings on mild or black steel. Because of the natural corrosion protection properties of the zinc cladding of galvanized metal, no additional passivation of the substrate is necessary as is required with existing processes on mild or black steel. Also, the invention relates to the hot dip or electroplated galvanized metal which has been pretreated by the process of this invention prior to application of an organic powder coating. Hot dip or electroplated galvanized metal treated by this process leads to a uniform coating which is virtually impervious to acid, basic and salt solutions, and which will not scratch or flake off on impact.
摘要翻译： 本发明涉及一种将有机材料（如粉末）应用于热浸或电镀镀锌金属的方法，该方法提供比在轻度或黑色钢上的有机涂层获得的更高水平的耐腐蚀性的成品材料。 由于镀锌金属的锌包层具有天然的防腐蚀性能，因此不需要对基材进行额外的钝化，这与现有工艺在温和或黑钢上所需要的一样。 此外，本发明涉及在施加有机粉末涂料之前已经通过本发明的方法预处理的热浸或电镀镀锌金属。 通过该方法处理的热浸或电镀镀锌金属导致均匀的涂层，其实际上不受酸，碱和盐溶液的渗透，并且在冲击时不会划伤或剥落。
