摘要/Abstract

摘要：

对超声波防垢法应用于商用开水器的防垢效果进行了实验研究, 对产生的水垢进行扫描电镜分析, 结果发现, 超声波具有加速生成微小水垢晶核的作用;超声波处理方法促进了商用开水器内温度较高的加热管结垢, 但对水箱壁面等低温壁面, 则具有明显的防垢效果, 而商用开水器结垢主要发生在加热管上, 因此超声波处理法不能运用于商用开水器的防垢。

Abstract:

Contrast experiments on scaling effect using ultrasonic scaling method on the commercial water boilers are performed and the formed water scale is analyzed by SEM (scanning electron microscopy). Results show that ultrasonic can accelerate the formation of the scale microcrystal nucleus. The ultrasonic scaling method can promote the scale of the heating tube with high temperature on commercial water boilers, while it decreases the scale on the low temperature plate, such as water tank surface. Since the scale is mainly taken place on the heating tube, this method is not suitable for commercial boiler.

Key words: ultrasonic, fouling, anti-scale, water boiler
