    超声波洗涤的小妙招有哪些?
    2016-4-19 13:16:47
    1、超声波的强度,即单位面积的声功率。超声清洗 效果的好坏取决于空化作用,空化作用与超声波强度有关。在通常情况下,单位面积(cm2)超过0. 3W声功率时(0. 3W/cm2),水溶液就能产生空化。超声强度越大,空化作用越明显,清洗作用也就越好。
    1, the ultrasound intensity, i.e. the sound power per unit area. The effect of ultrasonic cleaning depends on cavitation, cavitation and ultrasonic intensity. In general, per unit area (cm2) of more than 0 3W sound power (0 3W/cm2), aqueous solution can produce cavitation. The greater the intensity of ultrasonic cavitation effect, more obvious, the cleaning effect is better.
    2、超声频率:空化作用与超声频率有关。空化是随着频率的降低而降低。实践证明,低频时易于激发空化。16kH2〜25kHz时空化作用好。
    2, ultrasonic frequency and ultrasonic frequency on cavitation. Cavitation is reduced with the decrease of the frequency and. Practice has proved that the low frequency is easy to stimulate cavitation. 16kH2 ~ 25kHz space-time effect.
    3、清洗液的选择:不同的清洗液能获得不同的清洗效果。选择合适清洗液的依据是物体表面脏物的性质及溶液的表面张力、粘度等,脏物晕酸性的,选择碱溶液;相反则选择酸溶液。就空化特异性来说,选择有较大表面张力,较小粘度和蒸汽压力的液体作为清洗液都能获得较好的清洗效果。
    3, the choice of cleaning liquid: different cleaning solution can obtain different results. Select the appropriate cleaning liquid foundation is the dirt on the surface of an object and the nature of the solution such as surface tension, viscosity, dirt halo acid, alkali solution; on the contrary, acid solution. It has a larger specific cavitation, surface tension, viscosity and low vapor pressure liquid as cleaning liquid can obtain better cleaning effect.
    4、清洗的温度:温度是影响清洗速度的重要因素。适当地提高温度,可增强空化能力,缩短清洗时间。经试验表明,化学水溶液最佳清洗温度为60X:〜7(TC。因为 这时亲油基和亲水基之间的结合良好。同时,由于加热使液体表面张力增大,粘度减少,导致空化作用好,清洗效果亦好。
    4, cleaning temperature: the temperature is an important factor affecting the cleaning speed. Properly increasing the temperature, can enhance the ability of cavitation, shorten the cleaning time. The experimental results show that the chemical solution the best cleaning temperature: 60X ~ 7 (TC. Because of the combination between oil-based and water-based and pro good. At the same time, due to the heating, the liquid surface tension is increased, the viscosity is reduced, and the cavitation effect is good, and the cleaning effect is good.
    5、清洗时间:不同对象有不同的超声波清洗机的淸洗时间。例如,同一性质的油污,在使用过程中形成的油污所需淸洗时 间长,在生产过程中形成的油污所
    5, cleaning time: different objects have different ultrasonic cleaning machine cleaning time. For example, oil of the same nature, in use in the process of the formation of oil required Cheongju wash long, formed in the production process in oil
