The components of BX-BH red magnetic paste and BX-RH red magnetic paste: magnetic powder, wetting agent, dispersing suspension agent, defoaming agent, rust inhibitor.

Magnetic powder in magnetic paste: JB-350 black magnetic powder in BX-BH magnetic paste and JR-350 red magnetic powder in BX-RH magnetic paste meet the "wet method" in JB/T6063-92 "Technical Conditions for Magnetic Particles for Magnetic Particle Inspection" All technical requirements of "non-fluorescent magnetic powder dry powder for flaw detection".

Use of magnetic paste: add it to tap water and stir to disperse to form an aqueous suspension for magnetic particle inspection. Water consumption per liter: Extrusion length is 130-300 mm (weight is about 12-31g), and the concentration is determined to be 1.3-3.5ml/100ml.

The PH value of the magnetic paste configuration water magnetic suspension: 8-8.5

The wettability of the magnetic suspension: the bright surface of the steel has no liquid section.

Corrosion: Put the sandblasted or degreasing treated mild steel sample under working conditions, soak it in the magnetic suspension for 1 hour, take it out and place it in the air, observe for 24 hours, no rust spots.

Configure the flaw detection sensitivity of the magnetic suspension according to the recommended concentration: According to the JB/T6063-92 method, the B-type test block of JB/T6063-92 shows ≥5 holes, and the JB/T6063-2006I-type test block is clearly displayed. According to the 10D standard continuous method, the A-type test piece (15/100) is clearly displayed.

Toxicity: no harm to human body, no irritation to skin.
