超聲波清洗的效果與材料的彈性模量有關(guān)。利用高頻機(jī)械振動(dòng)的能量吸收強(qiáng)度的差異，不同材料剝離異物的幅度不同。塑料的彈性模量比金屬小很多，對(duì)超聲波的吸收也很強(qiáng)。由于質(zhì)地柔軟，塑料與不銹鋼有很大不同，耐腐蝕性差，不能在腐蝕性液體中清洗。其實(shí)我們應(yīng)該明白，不同材料對(duì)高頻機(jī)械振動(dòng)能的吸收是有很大差異的，塑性強(qiáng)度遠(yuǎn)小于金屬材料。

The effect of ultrasonic cleaning is related to the elastic modulus of the material. Using the difference of energy absorption intensity of high-frequency mechanical vibration, different materials have different ranges of stripping foreign matters. The elastic modulus of plastics is much smaller than that of metals, and the absorption of ultrasonic waves is also very strong. Due to its soft texture, plastic is very different from stainless steel, and its corrosion resistance is poor, so it cannot be cleaned in corrosive liquid. In fact, we should understand that the absorption of high-frequency mechanical vibration energy by different materials is very different, and the plastic strength is far less than that of metal materials.

實(shí)際上這是很有可能的。經(jīng)工廠工程師測(cè)試，普通塑料確實(shí)可以用超聲波清洗。清洗液的很好清洗溫度在50左右。特別是在寒冷的天氣里，如果我們放入的清洗液溫度低，空化效果就會(huì)變差，清洗效果也會(huì)變差。因此，我們?cè)谑褂贸暡ㄇ逑丛O(shè)備進(jìn)行清洗時(shí)，一定要學(xué)會(huì)根據(jù)不同的材料來控制超聲波清洗的溫度。如果控制不好，會(huì)對(duì)工件造成不可逆的損害。

In fact, it is quite possible. Through the test of professional engineers in the factory, ordinary plastics can indeed be cleaned by ultrasonic. The cleaning solution is very good. The cleaning temperature is about 50. Especially in cold weather, if the temperature of the cleaning solution we put in is low, the cavitation effect and cleaning effect will become worse. Therefore, when using ultrasonic cleaning equipment for cleaning, we must learn to control the ultrasonic cleaning temperature according to different materials. If the control is not good, it will cause irreversible damage to the workpiece.

此外在寒冷的天氣，如果清洗液溫度低，空化效應(yīng)不好，清洗效果自然也會(huì)差。當(dāng)溫度升高到合適的溫度時(shí)，空化氣泡內(nèi)氣體壓力增加，很終的清洗效果將會(huì)達(dá)到很佳。因此，發(fā)現(xiàn)有部分清洗機(jī)在清洗缸外邊繞上加熱電熱絲進(jìn)行溫度控制，當(dāng)溫度升高后空化易發(fā)生，所以清洗效果好。

In addition, in cold weather, if the temperature of the cleaning solution is low and the cavitation effect is not good, the cleaning effect will be poor. When the temperature rises to the appropriate temperature, the gas pressure in the cavitation bubble increases, and the final cleaning effect will be very good. Therefore, it is found that some cleaning machines wrap heating wires around the outside of the cleaning cylinder for temperature control. Cavitation is easy to occur when the temperature rises, so the cleaning effect is good.

當(dāng)溫度繼續(xù)升高以后，空泡內(nèi)氣體壓力增加，引起沖擊聲壓下降，反應(yīng)出這兩因素的相乘作用?，F(xiàn)市面上的超聲波清洗機(jī)都帶有溫度調(diào)節(jié)功能一般是常溫至95度可調(diào)，清洗時(shí)的具體溫度主要還是根據(jù)所清洗的物件及污垢來決定。

When the temperature continues to rise, the gas pressure in the cavity increases, causing the impact sound pressure to drop, reflecting the multiplication of these two factors. The ultrasonic cleaning machines on the market now have a temperature adjustment function, which is generally adjustable from normal temperature to 95 degrees. The specific temperature during cleaning is mainly determined by the cleaned objects and dirt.

如果針對(duì)清洗油污的污垢的話，清洗溶液需要有一定的溫度，清洗效果才會(huì)好，就像是我們?cè)谙赐霑r(shí)，加熱水和不加熱水的清洗效果是不一樣的，而超聲波清洗的水溫保持在50~60℃是很好的清洗溫度，主要這個(gè)溫度空化效果更好。

For cleaning oil dirt, the cleaning solution needs to have a certain temperature to achieve a good cleaning effect. For example, when we wash dishes, the cleaning effect is different between heated water and no hot water, while maintaining the water temperature of ultrasonic cleaning at 50~60 ℃ is a good cleaning temperature, and the cavitation effect of this temperature is better.

山東超聲波清洗機(jī)廠家認(rèn)為若加入清洗劑時(shí)，清洗劑則是溫度越高作用越顯著，溫度在50~60℃下，大部分活性酶是很活躍的，是物質(zhì)分解很高效的溫度區(qū)間，所以如果需要除油污的話，選擇50~60℃很為合適，目前市面上除油超聲波清洗機(jī)都帶有加熱功能的。

Shandong ultrasonic cleaning machine manufacturers believe that if the cleaning agent is added, the higher the temperature, the more significant the effect. At 50~60 ℃, most of the active enzymes are very active, which is a very efficient temperature range for material decomposition. Therefore, if it is necessary to remove oil stains, it is very appropriate to choose 50~60 ℃. At present, all the degreasing ultrasonic cleaning machines on the market have heating function.
