超聲波清洗的效果與(yǔ)材(cái)料的彈性模量有關。利用高頻機械振(zhèn)動的能量吸收強度的(de)差異,不同材料剝離異(yì)物的幅度不同。塑料的彈性模量比金屬小(xiǎo)很多,對(duì)超聲波的(de)吸收也很強。由(yóu)於(yú)質地柔軟,塑料與不鏽鋼有很大不同,耐腐蝕性差,不(bú)能在腐蝕性液體中清洗(xǐ)。其實91污應該明白(bái),不同材料對高頻機械振動能的(de)吸(xī)收是有很大差異的,塑性強度遠小於金屬材料。
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.
實際上這是很有可能的。經工廠(chǎng)工程師測試,普通塑料確實可以(yǐ)用超聲波清洗。清洗液的很(hěn)好清洗溫度在50左右(yòu)。特別是在寒(hán)冷的天氣(qì)裏,如果91污放入(rù)的清洗液溫度(dù)低,空化效(xiào)果就會變(biàn)差,清洗效果(guǒ)也會變差。因此,91污在使用超聲波清洗(xǐ)設備(bèi)進行清洗(xǐ)時,一定要學會根據不同的(de)材(cái)料來控製超聲波清洗的溫度。如果控製不(bú)好,會對工件造成不(bú)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(xǐ)效果自(zì)然也會差。當溫度升高到合適的溫度時,空化氣泡內氣(qì)體壓力(lì)增加,很終的清洗效果將會達到很佳。因(yīn)此,發現有部分清洗機(jī)在清洗缸外邊繞(rào)上加熱電熱絲進行溫度控製,當溫度升高後空化易發生,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.
當溫度繼續升高以後,空泡內氣體壓力增加,引起衝(chōng)擊聲壓下(xià)降,反應出這兩因素的(de)相乘作用(yòng)。現市麵上的超聲波清洗機都帶有溫度調節功能一般是常溫至95度可調,清洗時的具體溫度主要(yào)還是(shì)根據所清洗的物件及汙垢來決定。
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.
如果針對清洗油汙的汙垢的話(huà),清洗溶(róng)液(yè)需要有一定的溫度,清洗效果才會好,就像(xiàng)是91污在洗(xǐ)碗時,加(jiā)熱水和不加熱水的清洗(xǐ)效果(guǒ)是不(bú)一樣的,而超聲波清洗的水溫保持在50~60℃是很好的清(qīng)洗(xǐ)溫度,主要這個溫度空化(huà)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.
山東超聲波清洗機廠家認為若加入清洗劑時,清洗劑則(zé)是溫度越高作(zuò)用(yòng)越顯(xiǎn)著,溫度在50~60℃下,大部分活性酶是很(hěn)活躍的,是物質分解很高效的溫度區間(jiān),所以如果需要除油汙的話,選(xuǎn)擇50~60℃很為(wéi)合適,目前市麵上除油超聲波清洗機都帶有加熱(rè)功能(néng)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.
