想要發揮超聲波清洗機的最大效能，必須理解并合理設置以下三個核心參數：

To maximize the efficiency of an ultrasonic cleaning machine, it is essential to understand and appropriately set the following three core parameters:

超聲波頻率：頻率越低，空化氣泡越大，沖擊力越強，適合清洗重油污或結構堅固的工業零件（如28kHz）；頻率越高，空化作用越溫和且密集，適合清洗精密、易損的物件（如68kHz-100kHz的光學鏡片或電子元件）。

Ultrasonic frequency: The lower the frequency, the larger the cavitation bubbles and the stronger the impact force, making it suitable for cleaning heavy oil stains or industrial parts with sturdy structures (such as 28kHz); the higher the frequency, the more gentle and dense the cavitation effect, making it suitable for cleaning precision and fragile items (such as optical lenses or electronic components within the frequency range of 68kHz-100kHz).

功率密度：功率并非越大越好。功率密度過低會導致清洗無力，而過高則可能對工件表面造成“空化腐蝕”或損傷。通常需要根據工件的材質和臟污程度，將功率密度控制在合理區間（如0.3-0.8W/cm2）。

Power density: Higher power is not necessarily better. Too low a power density can lead to weak cleaning, while too high a power density may cause "cavitation erosion" or damage to the surface of the workpiece. Generally, the power density needs to be controlled within a reasonable range (such as 0.3-0.8W/cm2) based on the material and dirt level of the workpiece.

清洗液溫度：溫度對空化效應有顯著影響。一般來說，將清洗液溫度控制在40℃-60℃之間，能有效降低液體的粘度和表面張力，使空化效應更容易發生，從而大幅提升清洗效率。

Cleaning fluid temperature: Temperature has a significant impact on cavitation effect. Generally speaking, controlling the cleaning fluid temperature between 40℃-60℃ can effectively reduce the viscosity and surface tension of the liquid, making cavitation effect easier to occur, thereby greatly improving cleaning efficiency.

超聲波清洗機以科技之力，讓清潔變得高效、環保且無損。了解其背后的空化原理，能幫助我們更好地利用這一工具，讓生活與工作更加潔凈如新。
