由于超声波清洗的原理是空化效应,所以其性能验证主要是验证空化效应,目的是看清洗槽内声场强度是否存在盲区。
Because the principle of ultrasonic cleaning is cavitation effect, its performance verification is mainly to verify the cavitation effect, the purpose is to see whether there is a blind area in the intensity of the sound field in the cleaning tank.
1、我们可以用铝箔腐蚀方法进行超声波清洗机性能验证,将20-30微米厚的铝箔纸放在支架上,垂直放置在清洗槽内,不要碰到底部。机器启动一段时间后,铝箔表面不同部位的腐蚀程度可以间接反映出超声波强度的深度是否均匀。
启航彩We can use the aluminum foil corrosion method to verify the performance of the ultrasonic cleaning machine. Put the 20-30 micron thick aluminum foil on the bracket and vertically place it in the cleaning tank without touching the bottom. After the machine starts for a period of time, the corrosion degree of different parts on the aluminum foil surface can indirectly reflect whether the depth of ultrasonic intensity is uniform.
2、如果要检测超声波在水平方向上的强度分布,可以将铝箔水平放置。该方法直观、简便,但不能定量检测,误差较大。在装填设备的条件下难以进行试验,可能与碱性清洗剂发生化学反应。
启航彩2. If the intensity distribution of ultrasonic wave in horizontal direction is to be detected, the aluminum foil can be placed horizontally. The method is intuitive and simple, but it can't be used for quantitative detection, and the error is large. It is difficult to carry out the test under the condition of loading equipment, and may react with alkaline detergent.
3、也可以用滑动冲洗法验证,每周用HB铅笔涂玻片,3分钟内用超声波清洗干净。记录结果。该方法操作简单,但不能定量检测,误差较大。
启航彩3. It can also be verified by sliding washing method. Smear the slide with HB pencil every week and clean it with ultrasonic wave within 3 minutes. Record the results. This method is simple to operate, but it can't detect quantitatively, and the error is large.
4、或者是用淀粉碘化钾反应方法超声波清洗机性能验证。将淀粉处理成光敏乳剂,涂在载玻片上,置于含有稀释碘溶液的超声波容器中。在超声空化作用下,碘和淀粉发生反应变成蓝色,导致玻片变色。对玻片进行冲洗干燥,通过对玻片变色区域的观察,推断出声场的分布。该方法可以弥补铝箔腐蚀法中铝箔损伤的缺陷,但不能进行定量检测。
4. Or starch potassium iodide reaction method is used to verify the performance of ultrasonic cleaning machine. Starch was treated into photosensitive emulsion, coated on glass slide and placed in ultrasonic container containing diluted iodine solution. Under the action of ultrasonic cavitation, iodine reacts with starch and turns blue, resulting in the discoloration of glass slide. The slide was washed and dried, and the distribution of sound field was deduced by observing the discoloration area of the slide. This method can make up for the defect of aluminum foil damage in aluminum foil corrosion method, but it can not be used for quantitative detection.
5、染色法也是验证超声波清洗机性能的方法之一,水分配染料,超声波将涂在水中,超声空化作用下,染料会附着在纸上,取出纸冲洗干燥。观察染料模式的背景,对声场的分布,如果不均匀分布的涂层,声场不均匀,如寒冷的地方。
5. Dyeing method is also one of the methods to verify the performance of ultrasonic cleaning machine. The dye is distributed by water and applied by ultrasonic wave. Under the action of ultrasonic cavitation, the dye will adhere to the paper and take out the paper for washing and drying. Observe the background of the dye mode, the distribution of the sound field, if the uneven distribution of the coating, the sound field is uneven, such as cold places.
6、超声波能量瓶试验超声波清洗机性能验证的时候,所需变色时间与超声空化能力成正比。根据水箱容积,将测能瓶置于不同位置,观察换色时间。该方法直观、简便,而且是定性测量。
6. When the ultrasonic energy bottle test is used to verify the performance of the ultrasonic cleaning machine, the required discoloration time is directly proportional to the ultrasonic cavitation ability. According to the volume of the water tank, put the energy measuring bottle in different positions and observe the color change time. The method is intuitive, simple and qualitative.
