▎ 摘　　要

NOVELTY - Graphene-added ultrasonic nondestructive testing coupling agent comprises 10-40% solvent, 1-3% gelling agent, 1-3% colloidal stabilizer, 0.02-2% water-soluble rust inhibitor, 0.05-2% additives and balanced water. USE - Graphene-added ultrasonic nondestructive testing coupling agent. ADVANTAGE - The graphene-added ultrasonic nondestructive testing coupling agent has good acoustic characteristics, anti-corrosion performance, low viscosity and high fluidity, can balance viscosity of the coupling agent, and makes test results more accurate and credible, and can optimize coupling effect and improve ultrasonic transmission efficiency to obtain accurate detection results.
