ULTRASOUND CONTROL METHOD Mooney viscosity polymers

摘要

Method of ultrasonic testing in the Mooney viscosity of polymers comprising radiation pulses ultrasonic vibration emitter, the reception pulses passing sample receiver, the measurement of their propagation velocity and the attenuation factor of ultrasonic vibrations, characterized in that the measured parameters of the ultrasonic oscillations determines the viscosity of the polymer Mooney according to the formula: mh - Mooney viscosity units. Mooney; ρ - density of the polymer, kg / m; c - the speed of ultrasound in m / s; α - ultrasonic attenuation coefficient m; ω - ultrasonic testing frequency with; Z and Z- model parameters, individual for each grade of rubber.
