Zyglo® is the preferred penetrant inspection method for the extremely sensitive fluorescent detection of cracks and surface discontinuities in ferrous & non-ferrous test materials. Zyglo® liquid fluorescent penetrant inspection products are formulated from high quality fluorescing dyes and solvents to provide superior indications of extremely ...

Developed for testing materials that can be affected by petroleum-based penetrants, ZL-4C water-based fluorescent penetrant contains no petroleum derivatives and is harmless to materials that can be attacked by petroleum-based solvents, such as plastics. It is also safe for use on ceramics, and it can be used as a leak detector. PDS.

ZYGLO ZL-37是用于荧光渗透检测的一种性能优秀的渗透液，在紫外线照射下呈现明亮黄绿荧光。 它与其它后乳化型渗透液一样，因不含乳化剂，需要与亲油性或亲水性乳化剂一同使用， 才能具有水洗性，因此提高了渗透液在小缺陷内的停留能力，有效避免出现过洗现象。 它具有 较高的闪点，符合OSHA 对Class III B 类液体的要求，因而可在开口的槽内使用。 应用范围： ZYGLO ZL-37 主要用于关键部件（如钛涡轮元件等其它高应力零件）的平滑、非多孔性、精加 工表面的裂 …

ZYGLO® ZL-15B, ZL-19, ZL-60C, ZL-60D, ZL-67B and ZL-56 are fluorescent water- washable penetrants with excellent controlled washability over a wide temperature range. With a UV-A light source, indications will appear as a bright green-yellow fluorescence.

Zyglo® ZL‐37 (Level 4, Ultra‐High Sensitivity): Ideal for titanium turbine components, investment castings and other high stress critical components where detection of fine, tight and broad open shallow discontinuities is required.

A high-sensitivity Level 3 penetrant, ZL-67 fluorescent water removeable penetrant is designed to find smaller, finer indications in safety-critical components common to aerospace and engineering applications. ZL-67 penetrant is often used to find flaws in investment castings, jet engine components, and highly machined surfaces. PDS.

2017年4月13日 · The document presents a seminar on the Zyglo fluorescent penetrant test non-destructive testing method, which involves 6 steps: part preparation, application of penetrant, removal of penetrant, part drying, application of developer, and inspection under black light to locate surface defects like cracks in materials like metals and plastics.

Zyglo® – Emulsifier ZE-4E (Replaced ZE-4B) Choose Size for Pricing A Method B lipophilic emulsifier, ZE-4E diffuses into the penetrant to clear the penetrant from the surface of the part being inspected.

2025年3月7日 · Zyglo testing is a type of fluorescent penetrant inspection (FPI) technique used to identify surface flaws in metals and non-metal materials. The process involves applying a special dye that penetrates any surface cracks or defects, making them visible under ultraviolet (UV) light.

Zyglo ® is the preferred penetrant inspection method for the extremely sensitive fluorescent detection of cracks and surface discontinuities in ferrous & non-ferrous test materials. Zyglo ® liquid fluorescent penetrant inspection products are formulated from high quality fluorescing dyes and solvents to provide superior indications of ...
