超聲波清洗塑料

Ultrasonic cleaning of plastics

超聲波清洗效果與材料的彈性模量有關(guān)。利用高頻機(jī)械振動(dòng)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得多，同時(shí)對(duì)超聲波的吸收也很強(qiáng)。

The effect of ultrasonic cleaning is related to the elastic modulus of the material. According to the difference of energy absorption intensity of high-frequency mechanical vibration, the extent of foreign matter stripping is different for different materials. The elastic modulus of plastic is much smaller than that of metal, and it also has strong absorption of ultrasonic wave.

塑料由于質(zhì)地柔軟，與不銹鋼有很大區(qū)別，防腐性能差，在腐蝕性液體中無法再清洗。其實(shí)我們應(yīng)該可以理解，不同的材料對(duì)高頻機(jī)械振動(dòng)能量的吸收是有很大差別的，塑性強(qiáng)度遠(yuǎn)遠(yuǎn)小于金屬材料。那么，面對(duì)超聲波清洗，我們能抵抗超聲波的作用嗎？

Plastic is very different from stainless steel due to its soft texture and poor corrosion resistance. It can no longer 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. So, in the face of ultrasonic cleaning, can we resist the effect of ultrasonic?

其實(shí)是有可能的。經(jīng)過工廠工程師檢測(cè)，普通塑料確實(shí)可以用超聲波清洗。清洗液的佳清洗溫度為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，空化效果會(huì)很差，清洗效果也會(huì)很差。

Actually, it is possible. After testing by professional engineers in the factory, ordinary plastics can indeed be cleaned by ultrasonic. The optimal cleaning temperature of the cleaning solution 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 be very poor.

因此，我們?cè)谑褂萌詣?dòng)超聲波清洗機(jī)進(jìn)行清洗時(shí)，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傷。

Therefore, when we use the full-automatic ultrasonic cleaning machine for cleaning, we should learn to control the ultrasonic cleaning temperature according to different materials. If it is not well controlled, it will cause irreversible damage to the workpiece.

超聲波清洗硅膠

Ultrasonic cleaning silica gel

因?yàn)楣枘z是靠吸收空氣中的水分固化的，表面很容易吸附和滲透各種有機(jī)物，有機(jī)物在潮濕、陰暗的環(huán)境的下，不可避免地變質(zhì)，發(fā)黑、發(fā)霉。另外硅膠表面上也有可能有灰塵、雜質(zhì)等，影響美觀和質(zhì)量必須清洗硅膠。

Because silica gel is solidified by absorbing moisture in the air, the surface is easy to absorb and penetrate various organic substances. Organic substances inevitably deteriorate, blacken and moldy in a humid and dark environment. In addition, there may be dust and impurities on the surface of silica gel, which will affect the appearance and quality. Silica gel must be cleaned.

用超聲波清洗機(jī)清洗，并且超聲波清洗機(jī)能有效清洗掉硅膠上的霉斑、灰塵、雜質(zhì)等。超聲波的清洗原理不難理解，超聲波是一種物理清洗方法（空化作用）。

Use the ultrasonic cleaning machine to clean, and the ultrasonic cleaning machine can effectively clean the mildew, dust, impurities, etc. on the silica gel. The principle of ultrasonic cleaning is not difficult to understand. Ultrasonic is a physical cleaning method (cavitation).

換能器轉(zhuǎn)換成高頻機(jī)械振蕩而傳播到介質(zhì)中，超聲波在清洗液密相間的向前輻射，能夠產(chǎn)生數(shù)以萬計(jì)的微小氣泡，然而產(chǎn)生空化作用，聯(lián)系不斷在被清洗物表面形成小“爆炸”，使物件的表面及縫隙中的污垢迅速剝落，從而達(dá)到物件表面清洗凈化的目的，當(dāng)然選擇合適的清洗劑配合使用才能取得的清洗效果。

The transducer is converted into high-frequency mechanical oscillation and propagated to the medium. The forward radiation of the ultrasonic wave in the cleaning solution can produce tens of thousands of tiny bubbles. However, it produces cavitation, which constantly forms small "explosions" on the surface of the cleaned object, causing the dirt on the surface and cracks of the object to peel off rapidly, so as to achieve the purpose of cleaning and purifying the surface of the object, Of course, choosing the appropriate cleaning agent can achieve excellent cleaning effect.

全自動(dòng)超聲波清洗機(jī)清洗硅膠效果好、清洗速度快，功效高，能夠大大降低清洗員工作業(yè)勞動(dòng)強(qiáng)度，特別是現(xiàn)階段大批量的硅膠，超聲波清洗方法特別適用于硅膠，不但提高工作效率，還使硅膠的潔凈程度得到了充分的保證和效果，充分發(fā)揮了超聲波清洗機(jī)的使用率，做到車間利益大化。

The full-automatic ultrasonic cleaning machine has good cleaning effect, fast cleaning speed and high efficiency. It can greatly reduce the labor intensity of cleaning staff, especially for large quantities of silica gel at this stage. The ultrasonic cleaning method is especially suitable for silica gel, which not only improves the work efficiency, but also fully guarantees and effects the cleanliness of silica gel, gives full play to the utilization rate of ultrasonic cleaning machine, and maximizes the benefits of the workshop.
