清洗機槽體絕不僅僅是盛放清洗液的容器，它是超聲波傳播與工件承載的直接載體。槽體的材質與結構直接決定了設備的清洗效果、使用壽命以及整體性能。具體影響主要體現在以下四個核心方面：

The cleaning machine tank is not just a container for holding cleaning solution, it is a direct carrier for ultrasonic propagation and workpiece bearing. The material and structure of the tank directly determine the cleaning effect, service life, and overall performance of the equipment. The specific impact is mainly reflected in the following four core aspects:

1. 決定超聲波能量的傳導效率

1. Determine the conduction efficiency of ultrasonic energy

超聲波需要通過槽體壁輻射到清洗液中才能引發空化效應。金屬材質（如不銹鋼）能夠高效傳導聲波，而塑料或橡膠等材料會吸收或阻礙聲波，抑制空化作用的產生，從而大幅降低清洗效果2。此外，槽體的厚度至關重要：厚度在2.5-3mm時諧振效率最高；若薄于2mm，槽體在長期高頻振動下極易發生變形；若厚于3.5mm，則會導致諧振損耗增加約30%，削弱清洗力度1。

Ultrasonic waves need to be radiated through the tank wall into the cleaning solution to trigger cavitation effects. Metal materials (such as stainless steel) can efficiently conduct sound waves, while materials such as plastic or rubber can absorb or obstruct sound waves, suppress the generation of cavitation, and significantly reduce cleaning efficiency. In addition, the thickness of the groove is crucial: the resonance efficiency is highest when the thickness is between 2.5-3mm; If it is thinner than 2mm, the groove body is prone to deformation under long-term high-frequency vibration; If it is thicker than 3.5mm, it will cause an increase of about 30% in resonance loss and weaken the cleaning force by 1.

2. 影響設備的耐腐蝕性與使用壽命

2. Affects the corrosion resistance and service life of equipment

超聲波在液體中產生的空化氣泡在崩潰瞬間會釋放極高的瞬時壓力和局部高溫，并伴隨高速微射流，這對槽體材料是極大的物理考驗。塑料、鋁或劣質不銹鋼往往無法承受這種反復沖擊，容易出現表面疲勞、微裂紋甚至穿孔泄漏4。相比之下，優質的304或316L不銹鋼具備出色的抗振性和耐腐蝕性。特別是添加了鉬元素的316L不銹鋼，對強酸、強堿及氯離子具有卓越的防護能力，是實驗室及嚴苛工業場景的首選1。

The cavitation bubbles generated by ultrasound in liquid will release extremely high instantaneous pressure and local high temperature at the moment of collapse, accompanied by high-speed microjet, which is a great physical test for the tank material. Plastic, aluminum, or inferior stainless steel often cannot withstand such repeated impacts, and are prone to surface fatigue, microcracks, and even perforation leaks. In contrast, high-quality 304 or 316L stainless steel has excellent vibration resistance and corrosion resistance. Especially 316L stainless steel with added molybdenum element has excellent protection against strong acids, alkalis, and chloride ions, making it the preferred choice for laboratory and harsh industrial scenarios.

3. 關乎清洗的衛生標準與防污染能力

3. Hygiene standards and pollution prevention capabilities related to cleaning

槽體材料的表面特性直接影響清洗物品的潔凈度。不銹鋼具有致密、光滑的表面，能夠有效抵抗污染物附著，避免細菌、油脂或化學殘留物滲入材料內部。這對于醫療器械消毒、半導體制造及食品加工等對衛生標準要求極高的領域尤為關鍵4。相反，劣質或回收廢鋼制作的內槽在長期接觸清洗液后，可能會析出鉛、鉻等重金屬，不僅污染清洗物品，還會帶來安全隱患。

The surface characteristics of the tank material directly affect the cleanliness of the cleaning items. Stainless steel has a dense and smooth surface, which can effectively resist the attachment of pollutants and prevent bacteria, grease, or chemical residues from infiltrating the interior of the material. This is particularly crucial for fields such as medical device disinfection, semiconductor manufacturing, and food processing that require extremely high hygiene standards. On the contrary, internal tanks made from inferior or recycled scrap steel may precipitate heavy metals such as lead and chromium after long-term exposure to cleaning solutions, which not only contaminate the cleaning items but also pose safety hazards.

4. 決定聲場分布的均勻度

4. Determine the uniformity of the sound field distribution

清洗槽的結構完整性有助于維持聲波的均勻傳播。如果槽體材質較差或存在結構缺陷，隨著長期使用的磨損，極易導致波形畸變或在槽內形成清洗效果極差的“死區”4。采用激光焊接等精密工藝制造的優質不銹鋼槽體，能夠確保從第一天到數千次循環都能獲得一致且均勻的清洗效果4。

The structural integrity of the cleaning tank helps maintain the uniform propagation of sound waves. If the material of the tank body is poor or there are structural defects, it is easy to cause waveform distortion or form a "dead zone" with extremely poor cleaning effect in the tank with long-term wear and tear. High quality stainless steel tanks manufactured using precision processes such as laser welding can ensure consistent and uniform cleaning effects from the first day to thousands of cycles.
