摘要
在对国内外清洗预膜剂进行广泛调研的基础上，通过一系列的试验研究，研制出一种高效的低磷清洗预膜剂并工业应用．结果表明：该清洗预膜剂对系统的清洁能力强、缓蚀性能佳、适应范围宽．产品磷含量极低、性能价格比高．尤其适合系统容量大、环保要求高的循环冷却水系统．
Based on widely inrestigating and researching for the clean and preform-film agent and a series of test and studies, a kind of low-phosphorus clean and preform-film agent with high efficiency was developed. It shows that this clean and preform-film agent has high-cleaning ability with good anti-corrosion property, wide application range, low phosphorus content and high ratio of price to property. It is specially suited to large capacity circulative water system in which environmental protection is highly required.
