金属搪瓷传热元件及其加工方法
摘要：
本发明提供一种可适用于露点温度以下及酸、碱腐蚀性介质中的具有抗腐蚀性能的金属搪瓷传热元件，包括传热元件及其表面敷设的金属搪瓷层；所述金属搪瓷层为防腐柔性金属搪瓷层，其在普通搪瓷料中加入金属元素，各金属元素重量比为：Ti0.01~0.1%、Cu0.1~0.2%、Co0.2~0.5%、Mg0.1~0.5%、Mo0.01~0.05%。本发明可用于回收腐蚀性介质或低温露点温度以下的余热回收装置，有利于大幅度提高设备使用寿命，降低设备成本和维护费用。
摘要（英）：

The invention provides a metal enamel heat transmission element with corrosion resistance performance and applicable to acid and alkali corrosive mediums with temperature lower than a dew point temperature. The metal enamel heat transmission element comprises a heat transmission element and an anticorrosive flexible metal enamel layer coated on the surface of the heat transmission element, metal elements added into normal enamel materials includes: by weight, 0.01-0.1% of Ti, 0.1-0.2% of Cu, 0.2-0.5% of Co, 0.1-0.5% of Mg and 0.01-0.05% of Mo. The metal enamel heat transmission element can be used for a waste heat recovery device for recovering corrosive mediums or waste heat recovering at low dew point temperature, service life of equipment is benefited to be greatly prolonged, and equipment cost and maintenance cost are reduced.
