Method D: Hydrophilic Emulsifier
基本信息 GENERAL DESCRIPTION
E-10 亲水乳化剂具有如下优点：仅仅乳化掉工件表面的渗透剂，使渗透到缺陷中的渗透剂*大程度保留，提高渗透检测的灵敏度，在粗糙表面有*低的荧光背景。可通过浓度和乳化时间来控制后乳化渗透剂的去除效果，带来*可靠和可重现的测试结果。
Utilization of E-10 Hydrophilic Emulsifier affords such advantages as: minimization of fluorescent background on rough surfaces, minimization of bleed-out from hollow parts, reduced consumption of expendable materials, ease of use in closed loop systems and reduced effluent pollutants. E-10 Hydrophilic Emulsifier yields the most reliable and reproducible test results due to its controlled PE penetrant removal.
预清洗 PRE-RINSE
在施加亲水乳化剂如 E-10 前，建议进行预清洗。预清洗是通过喷淋清洗去除工件表面的大部分的荧光渗透液，然后再进入乳化液槽。有效的预清洗可降低渗透液对乳化液的污染，延长乳化液的使用时间。
The pre-rinse step is recommended before the application of a hydrophilic emulsifier like E-10. Pre- rinse is a water spray employed to mechanically reduce the film of PE penetrant on a part before entering the emulsifier bath. This process step prolongs the emulsifier bath life by lowering the amount of penetrant contaminating the bath. The pre-rinse and hydrophilic emulsifier processes are ideally suited for closed loop low pollution systems.
施加方法 METHOD OF APPLICATION
E-10 在作为乳化剂时需要用水稀释。亲水性乳化剂通常用喷雾或浸泡方式施加。配比浓度会决定清洗工件表面渗透剂所需的时间。
E-10 concentrate is diluted in water before it is used as an emulsifier/remover. The hydrophilic emulsifier is generally employed as a spray or an immersion dip. The concentration used will determine the amount of contact time required to remove the surface penetrant.
喷淋法 SPRAY METHOD
如果使用喷淋法，可使用注射套件来调节浓度。一般的浓度范围是 1%至 5%。喷淋去除施加时，应在黑光灯光照射下进行，以控制工件表面渗透液的去除。建议之后用干净的水冲洗，洗掉乳化剂/渗透剂的残留。
If the spray method of emulsifier application is used, an injector or metering pump is used to control the concentration. The general spray concentration range is 1% to 5% remover. Spray removal should be employed under black-light illumination to control removal of penetrant from the surface. A clean water rinse is recommended to eliminate emulsifier/penetrant residues.
浸泡法 IMMERSION METHOD
如果采用浸泡法，通常乳化剂相对水的浓度比例是 20%。采用推荐的 20%浓度，可优化乳化剂的效果，乳化液的使用寿命，节省成本和优化过程。渗透检测的工件整体浸入乳化液槽后，轻轻搅拌乳化液或采用通压缩空气的方法搅拌。工件的浸泡时间可根据不同的乳化液槽的浓度、渗透类型以及规范要求和需要达成的效果而调整。在20%的浓度情况下，浸泡时间一般控制在 30 到 180 秒之间。浸泡之后，可以用清水喷淋洗去残留的渗透液和乳化液。
If the immersion dip method is employed the general concentration range is 20% remover to water. The recommended concentration is 20% which optimizes remover activity, bath life, economics and process rate. The penetrated part is immersed in the bath, which is gently agitated by mechanical or air means. The length of time the part is in the bath will vary with the concentration of the bath, the type penetrant being used, specification requirements and the desired results.At 20% concentration the immersion contact time generally ranges between 30 - 180 seconds. The immersion dip is followed by a clean water spray to remove any penetrant/emulsifier residues.

浓度控制 CONCENTRATION CONTROL
乳化液的浓度可以使用折射仪进行监控。此外，可以使用 ASTM D-95 所描述的方式确定乳化液槽中的水含量。
The concentration of hydrophilic remover baths can be monitored using a refractometer and concentration chart. The water content of the bath can also be determined using the procedure described in ASTM D-95.
