Aluminium surface treatment - Import export

The dimensionCONTROL TMWI 8302.LC system is suitable for the inline weight inspection of continuous running rubber profiles (tread pattern or sidewalls) for passenger and truck tires. Based on the force measurement principle, the inspection system uses two load cells which measure the deflection of the measurement conveyor. These sensor elements are attached to a massive construction, which ensures a long-term mechanical stability of the system. The measurement conveyor uses precise and balanced aluminum rollers with special surface treatment. This ensures a low deadweight, avoids influence of unbalance and eliminates material sticking. Data obtained from the load cells are processed in the implemented PLC cards which determine the measured weight mathematically.The software included offers a variety of measurement data processing, definition of design profiles, statistical analysis of measured profiles and diagnostic tools.

The effect achieved by the corona treatment is an increase in surface tension to values between 38 to 60 mN/m. Since the surface tension is caused by dispersive and polar interaction components the introduction of polar functional groups in particular increased the polar component of the surface tension.
