乳化剂ZE-4B.

一种方法B亲脂性乳化剂，ZE-4B扩散到渗透剂中，以从被检查的部件的表面清除渗透剂。它由水冲洗水，从部分表面上脱气。设计用于可乳化后的渗透剂级2 ZL-2C，3级ZL-27A或4级ZL-37，益处包括低挥发性，并且高闪点，因此ZE-4B可用于开放浸泡罐。•Low volatility •High flash point •Fast acting for quick processing times •Supplied ready to use" •Biodegradable •Safe to use on all aerospace alloys, e.g. aluminium, steel, nickel, titanium Product Properties NDT TypeFluorescent Penetrant Testing, Visible Penetrant Testing Penetrant TypeType 1, Type 2 Penetrant MethodsMethod B Applications Ideal ApplicationCastings, Extrusions, Forgings, Open immersion tanks Defect ExamplesCracks, Laps, Seams Compliance StandardsAMS 2644, ASME BPVC, ASTM E1417/E1417M, ASTM E165/E165M-18, MIL-STD-2132D SPECIFICATION COMPLIANCE • AMS2644 • ASME BPVC-V • ASTM E165/E165M-18 • ASTM E1417/E1417M • MIL-STD-2132D APPLICATIONS Defect location: open to surface Ideal for: • Use in open immersion tanks • Castings • Forgings • Extrusions Defect examples: • Cracks • Seams • Laps COMPOSITION A blend of emulsifying agents and oils.
