Product Description

Operation Manual of Anti rust and Anti freezing Environmental friendly Ultrasonic Weld Flaw Detection Couplant

 

This product is a water-based formula composed of surfactant, rust inhibitor, softener and wetting agent. It is used for coupling of ultrasonic flaw detection, with good coupling performance, and can effectively reduce the loss of ultrasonic sound energy. It is easy to clean with water, harmless to human body, pollution-free to the environment, and has anti freezing and anti rust properties.

[Ingredients]: surfactant, rust inhibitor, antifreeze, wetting agent, softener, etc. This product is a water-based gel coupling agent.

[Character]: colorless transparent or blue transparent gel.

[Scope of application]: This product is applicable to ultrasonic testing, flaw detection and thickness measurement of metal structures, railways, chemical equipment, ships, aircraft, automobiles, steel structures, weapons, nuclear industry, transportation, boiler pressure vessels, medical equipment, castings and forgings in the construction industry, especially various types of welding seam testing. In particular, it is recommended that users use gel type agents on rough surfaces, such as sand casting metal and glass fiber joints.

(4) JNT-50 (temperature range - 50 ℃ to 90 ℃)

[Loading capacity] (1) 500g/bottle; (2) 25Kg/barrel

 

[Usage]: Evenly apply the product on the part to be tested. Grind the rough surface, and then conduct ultrasonic flaw detection and thickness measurement. After that, use cloth and paper (or deionized water, or dry cloth)

[Features]: good coupling performance; High acoustic impedance; Good lubrication performance, easy to use; No corrosion; No irritation, no allergy, no pollution, easy to remove.

(1) Gel couplant has high viscosity and relatively high acoustic impedance, so when the probe cannot contact the measured surface smoothly, the use of gel can greatly enhance the effect of acoustic coupling.

(2) Gel couplant is usually used in weld detection, in which the probe needs to be slid on a wide surface. Here, the advantage of using gel is that gel can quickly cover a large area, and gel can maintain a good coupling effect when the probe scans along the weld.

(3) Since the gel type couplant will not drop or flow, it is also applicable to the detection of the upward or vertical detection surface.

(4) Most of the gel couplant can be used on the surface to be measured with moderate heat at a temperature not exceeding about 90 ° C.

[Storage]: Store in a closed and cool place.

[Shelf life]: three years.

[Tips] Couplants with different viscosities can be customized according to the actual needs of customers.
