介绍了蒸发式冷却器的防腐方法。据称,蒸发冷却器受到循环水化合物和空气中杂质的强烈的侵蚀。制造厂早就熟知这种冷却器的腐蚀问题。通常想不用碳素钢而采用增强塑料或不锈钢,但实际上碳素钢仍无法避免采用。不管对碳索钢采取何种防腐手段,安装时还可能损坏防腐层而最终影响腐蚀。有鉴于此,巴尔的摩空气盘管公司(BaltimoreAircoil Co.)提出了一种 Baltibond 防腐系统,并已在10万台产品上取得成功经验。该防腐系统的要点是:碳素钢基本结构承受热镀锌,以提供整体防腐。在加工结束和装配之前,要进行四步处理:清理、预处理、喷淋和烘干。此后运输系统保
Anticorrosive methods of evaporative cooler are introduced. Evaporative coolers are said to be strongly eroded by circulating water compounds and impurities in the air. The factory has long been familiar with the problem of corrosion of such coolers. Usually do not want to use carbon steel reinforced plastic or stainless steel, but in fact carbon steel can not be avoided. Regardless of the anti-corrosion measures taken on the carbon steel, the installation may also damage the coating and ultimately affect the corrosion. In view of this, Baltimore Aercoil Co. has proposed a Baltibond anti-corrosion system and has achieved success on 100,000 units. The main points of this anti-corrosion system are: The basic structure of carbon steel is subjected to hot-dip galvanizing to provide overall corrosion protection. Four steps are required before finishing and assembly: cleaning, pre-treatment, spraying and drying. Since then transport system insurance
