1、什么是“空化作用”？
1. What is cavitation?
“空化作用”是數(shù)以百萬計(jì)微小氣泡(或空穴)在液體中迅速形成并爆裂的現(xiàn)象。“空化作用”的產(chǎn)生是由于高頻聲波(超聲波)形成的高、低壓力波交互作用的結(jié)果。在低壓階段，氣泡一點(diǎn)點(diǎn)變大，而在高壓階段，其被壓縮而內(nèi)爆。
"Cavitation" is a phenomenon that millions of tiny bubbles (or holes) are rapidly formed and burst in liquid. "Cavitation" is caused by the interaction of high and low pressure waves formed by high-frequency sound waves (ultrasonic waves). In the low pressure stage, the bubble becomes larger little by little, while in the high pressure stage, it is compressed and implodes.
2、我怎樣能實(shí)現(xiàn)超聲波清洗效果？
2. How can I achieve ultrasonic cleaning effect?
有許多條件能夠決的清洗效果，其中重要的是選擇合適的清洗液，在正確的溫度下清洗恰當(dāng)?shù)臅r(shí)間，選擇合適尺寸和類型的超聲波清洗機(jī)。
There are many conditions that can determine the cleaning effect. Among them, it is important to select the appropriate cleaning solution, clean at the right temperature for the right time, and select the appropriate size and type of ultrasonic cleaner.

3、用超聲波清洗會(huì)損傷我的工件么？
3. Will ultrasonic cleaning damage my workpiece?
超聲波清洗對(duì)大多數(shù)工件是安全的。每秒鐘數(shù)以千計(jì)氣泡的內(nèi)爆產(chǎn)生的能量是巨大的，但由于能量集中在出色其微小的區(qū)域內(nèi)，因此整個(gè)清洗過程是安全的。對(duì)安全性為謹(jǐn)慎的考慮應(yīng)該是清洗液的選擇。清洗液對(duì)某些工件表面潛在的傷害性可能會(huì)因?yàn)槭褂贸暡ǘ嵘?。超聲波清洗不建議應(yīng)用于下列寶石：貓眼石、珍珠、翡翠、坦桑黝簾石、孔雀石、綠寶石、青金石和珊瑚。
Ultrasonic cleaning is safe for most workpieces. The energy generated by the implosion of thousands of bubbles per second is huge, but because the energy is concentrated in an extremely small area, the entire cleaning process is safe. Careful consideration of safety should be the choice of cleaning solution. The potential harm of the cleaning solution to some workpiece surfaces may be increased due to the use of ultrasound. Ultrasonic cleaning is not recommended for the following gemstones: opal, pearl, emerald, tanzanite, malachite, emerald, lapis lazuli and coral.
4、什么是“直接”和“間接”清洗？
4. What are "direct" and "indirect" cleaning?
直接清洗通常是指工件在裝滿清洗液的清洗槽內(nèi)清洗，工件通常裝在帶孔的托盤或工裝籃內(nèi)。直接清洗的局限性是需要選擇那些不會(huì)損傷超聲波清洗槽的清洗液。間接清洗則是將待清洗的工件放在燒杯或不帶孔的托盤內(nèi)，燒杯或托盤內(nèi)裝有溶液，而不是直接裝在清洗槽內(nèi)。當(dāng)選擇間接清洗時(shí)，確認(rèn)槽內(nèi)的水位被保持在標(biāo)準(zhǔn)位置。
Direct cleaning usually means that the workpiece is cleaned in a cleaning tank filled with cleaning solution, and the workpiece is usually installed in a tray or tooling basket with holes. The limitation of direct cleaning is to select the cleaning solution that will not damage the ultrasonic cleaning tank. Indirect cleaning is to put the workpiece to be cleaned in a beaker or tray without holes, and the beaker or tray is filled with solution, rather than directly in the cleaning tank. When indirect cleaning is selected, confirm that the water level in the tank is maintained at the standard position.
