汽车冷却系统超声波-化学联合法清洗研究

对比研究了化学法、超声波法以及超声波-化学联合法对汽车冷却系统中通水管和散热器水垢的清洗效果,以清洗前后的质量变化率和腐蚀速率为衡量指标。结果表明,三种清洗方式的清洗的质量变化率依次为超声波-化学联合法>超声波法>化学法;化学法中选择以氨基磺酸为主的配方化学清洗,最高的清洗变化率可达3.87%,通水管和散热器铜片的腐蚀速率分别为1.27和1.20 mg/(cm2.h);超声波清洗的质量变化率最高可达3.92%,通水管和散热器铜片的腐蚀速率分别为0.002和0.001 mg/(cm2.h)。在超声波-化学联合法清洗效果中,选择氨基磺酸为主的配方+超声波清洗,质量变化率最高可达到6.13%,通水管和散热器铜片的腐蚀速率分别为3.29和3.28 mg/(cm2.h)。

Research on chemical-ultrasonic uniting cleaning of automotive cooling system

The incrustant of pipe and copper radiator test cleaning in automotive cooling system was studied in compare,including chemical cleaning,ultrasonic cleaning and chemical-ultrasonic uniting cleaning.The measurement is quality change rate and corrosion rate.The result showed that quality change rate was chemical-ultrasonic uniting cleaning>ultrasonic cleaning>chemical cleaning.Chemical cleaning is amino sulfonic acid which have the best quality change rate with 3.87%,the corrosion rate of pipe and copper radiator is 1.27 mg/(cm·h) and 1.20 mg/(cm·h).Ultrasonic cleaning have the best quality change rate with 3.92%,the corrosion rate of pipe and copper radiator is 0.002 mg/(cm2·h) and 0.001 mg/(cm2·h).In ultrasound-chemical cleaning,the choice of amino acid-based formula adding ultrasonic cleaning had the best quality change rate with 6.13%,the corrosion rate of pipe and copper radiator is 3.29 mg/(cm2·h) and 3.28 mg/(cm2·h).
