基本信息 GENERAL DESCRIPTION

FH-300H后乳化型荧光渗透液可广泛用于灵敏度要求比较高的渗透检测应用，因不含乳化剂，因此有效避免在缺陷处出现过洗现象，通常比同等级的水洗型产品具有更高的灵敏度。它们要求与亲油或亲水乳化剂一同使用，以使其具有水洗性，并由于闪点高，能完全满足OSHA对Class III B 类液体的要求，因而可在开口的槽内使用。

FH-300H post emulsifiable fluorescent penetrants are used for a wide range of sensitive applications and are formulated to be impervious to water to assure against being over-washed from defects，Usually has higher sensitivity than the barrel grade water-washable products. They require the application of a lipophilic emulsifier or a hydrophilic emulsifier to render them washable with water and meet OSHA requirements for Class III B liquids due to their high flash point, allowing them to be used in open dip tanks.

FH-300H后乳化型荧光渗透液在紫外线下呈现亮黄绿荧光色，推荐使用主峰波长365纳米的黑光灯。

FH-300H post emulsifiable fluorescent penetrants fluoresce a bright greenish-yellow color under ultraviolet radiation. Use of a black light source with a peak wavelength of 365nm is required.

产品特点 Product features

施加方法 METHOD OF APPLICATION

在施加渗透剂之前，工件必须清洁、 干燥、去油、 脂或其他污染物质。渗透液可通过浸泡、涂刷、倾倒、 常规或静电喷涂等方式施加到工件的待检区域。待检查的区域必须完全覆盖渗透液。

Test parts must be clean, free of all oil, grease or other foreign contaminating substances and dry before penetrant is applied. Penetrants may be applied by immersion, dip, brush or flow-on, conventional or electrostatic spray. The area to be inspected must be completely covered with penetrant.

典型性能 TYPICAL PROPERTIES

塑料材质兼容性 PLASTICS COMPATABILITY

渗透剂通常适用于尼龙、聚四氟乙烯、乙缩醛、聚丙烯和环氧树脂等塑料材质。但是，仍推荐使用实际的试块来验证渗透剂是否于该材质相兼容。否则，渗透剂可能会污染、软化甚至溶解某些塑料材质。

Penetrant materials are typically compatible with nylon, teflon, acetal, polypropylene, and epoxies. However, it is still recommended that the penetrant be evaluated for compatibility on actual test pieces. Penetrants may stain, soften, or even dissolve plastic materials.

去除渗透剂 PENETRANT REMOVAL

后乳化性渗透液需要与亲油或亲水的乳化剂配合使用，以使其具有水洗性。当对较小区域进行检测时，也可使用溶剂去除（方法C），通常可使用溶剂清洗剂。用清洗剂湿润擦拭布，然后擦拭覆盖有渗透剂的表面。请勿将清洗溶剂直接倾倒至工件表面，因为可能会对检测的灵敏度产生影响。

Post emulsifiable penetrants require the use of a lipophilic or hydrophilic emulsifier to render them water washable. For inspection of small areas, the solvent wipe technique (Method C) is commonly employed using solvent cleaner/remover. Moisten a clean wiping media with solvent cleaner/remover and wipe the inspection area free of surface penetrant. Do not flood the inspection surface with cleaner/remover because the sensitivity may be impaired.

施加显像剂 DEVELOPER APPLICATION

显像剂可以将缺陷指示放大，提高检测的灵敏度。水基显像剂应在干燥工序前施加；干粉或其他非水基显像剂，必须在干燥工序后施加。

Developers should be used to maximize the sensitivity of penetrants. Aqueous developers are applied prior to drying; dry powder and non-aqueous developers are applied after drying.

警告！在使用水基显像剂时，工件不宜长时间的泡在显像液中，因为这样会对渗透检测的灵敏度产生不利影响。

Warning! Parts should not remain in aqueous developers for any length of time, as the penetrant sensitivity could be impaired.
