9.1黄瓜视频使用的水需根据清洗对象和场景选择，以下是常见类型及适用情况：

　　The water used in ultrasonic cleaning machines needs to be selected according to the cleaning object and scene. The following are common types and applicable situations:

　　自来水

　　tap water

　　适用场景：日常简单清洗，如清洗普通金属零件、玻璃器皿等，对水质要求不高时可直接使用。

　　Applicable scenarioses: Daily simple cleaning, such as cleaning ordinary metal parts, glassware, etc., can be used directly when the water quality requirements are not high.

　　注意事项：需确保水质符合生活饮用水标准（GB 5749），避免水中杂质或矿物质影响清洗效果。

　　Attention: It is necessary to ensure that the water quality meets the standard for drinking water (GB 5749) and avoid impurities or minerals in the water affecting the cleaning effect.

　　软水

　　soft water

　　适用场景：清洗易生锈或对水质硬度敏感的金属零件、精密机械部件等，可减少水垢形成。

　　Applicable scenarioses: Cleaning metal parts, precision mechanical components, etc. that are prone to rust or sensitive to water hardness can reduce the formation of scale.

　　特点：通过软化处理去除部分钙、镁离子，降低水的硬度，适用于机械清洗预处理阶段。

　　Features: By softening treatment, some calcium and magnesium ions are removed, reducing the hardness of water, suitable for mechanical cleaning pretreatment stage.

　　纯化水/去离子水

　　Purified water/deionized water

　　适用场景：清洗电子元器件、光学镜片、医疗器械等对洁净度要求极高的物品。

　　Applicable scenarioses: Cleaning electronic components, optical lenses, medical equipment, and other items that require extremely high cleanliness.

　　特点：去除了水中的无机盐、有机物和微生物，电导率低（一般≤15μS/cm），能有效避免杂质残留。

　　Features: It removes inorganic salts, organic matter, and microorganisms from water, has low conductivity (generally ≤ 15 μ S/cm), and can effectively avoid residual impurities.

　　蒸馏水

　　distilled water

　　适用场景：需极高纯净度的特殊清洗任务，如实验室精密仪器、高精度光学部件清洗。

　　Applicable scenarioses: Special cleaning tasks that require extremely high purity, such as laboratory precision instruments and high-precision optical component cleaning.

　　特点：通过蒸馏去除非挥发性杂质和大部分微生物，纯度更高。

　　Features: By distillation, non-volatile impurities and most microorganisms are removed, resulting in higher purity.

　　选择建议：

　　Suggestion for selection:

　　若清洗普通物品，自来水或软水即可；

　　If cleaning ordinary items, tap water or soft water is sufficient;

　　清洗电子、医疗、光学等精密部件，优先选用纯化水或蒸馏水；

　　Clean precision electronic, medical, optical and other components, preferably using purified water or distilled water;

　　若使用清洗剂，需根据清洗剂要求选择匹配的水（如酸性清洗剂需用去离子水）。

　　If using cleaning agents, it is necessary to choose matching water according to the requirements of the cleaning agent (such as deionized water for acidic cleaning agents).

　　温馨提示：不同场景下用水标准有差异，医疗、电子等行业需严格遵循相关规范。使用前建议咨询设备制造商或专业清洗方案提供商，确保水质符合清洗需求。

　　Reminder: Water standards may vary in different scenarioses, and industries such as healthcare and electronics must strictly follow relevant regulations. Before use, it is recommended to consult with the equipment manufacturer or a professional cleaning solution provider to ensure that the water quality meets the cleaning requirements.
