Significant Improvements to Extrusion Coating Processing Aids, 1991 Polymers, Laminations & Coatings Conference Proceedings
Deriving true nett figures for power dissipated by Corona Generators at the web, the Lissajous power measurement, has triggered new generator designs permitting repeatability of values established in the research environment and has created a commonly recognised standard, against which, all vendors equipment can be compared.
The alternative adhesion promotion device, the gas/flame treater, has been refined for continuous monitoring on central computerizedPLC Systems. This enables a gas/air ratio control system to use electrical signals proportional to the mass flow rate of the gases. The result is, gas/air ratios independant of changes in temperature and humidity.
This paper describes how these process improvements have been achieved.
