1. COATING & LAMINATING SEMINAR June 3-4, 2007 – Rosemont, IL @ CMM International Jay Perry Simco Industrial Static Control 215-997-3418

2. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 2 Why is Web Cleaning Important? Production problems Reduced productivity Added labor costs Quality problems Costly production rejects Unhappy customers Reduced Profitability

3. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 3

4. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 4 Static Electricity Cause – Effect - Control Cause Definition Triboelectrification = Friction Triboelectric Series Chart Magnitude of Charge Cumulative Nature Typical Areas of Charge Generation Effect Control

5. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 5 Definition of Static Electricity

6. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 6 Triboelectrification “Tribo Charging” Contacting Surfaces Alignment of Electrons Separating Surfaces Exchange of Electrons One surface becomes negatively charged. One surface is left positively charged.

7. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 7 Triboelectrification

8. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 8 Triboelectric Series Chart Higher on the Chart Propensity to positive charge Lower on the Chart Propensity to negative charge

9. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 9 Triboelectric Series

10. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 10 Magnitude of charge is dependent upon: Types of materials in contact Surface resistivity Ambient humidity Web speed Contact surface area pressure friction

11. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 11

12. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 12 Typical areas where significant charges may be generated Unwind Nip rolls Accumulator Idler with insulative sleeve Bow roll Coating rolls Corona treater Lay-on roll

13. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 13 Effects of Surface Charges on Airborne Particles

14. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 14 Control Surface Charge as Opposite Polarity Ions from Static Bars are Attracted, Neutralizing the Web

15. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 15 Boundary Layer of Air Definition Problems for web cleaning Laminar Layer

16. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 16 Definition of Boundary Layer of Air

17. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 17 Boundary Layer Graph

18. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 18 Traps smaller particles, <20 micron Layer closest to the surface Suction effect Laminar Layer of Air

19. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 19 Laminar Layer Graph

20. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 20 Effective Particle Extraction Vacuum Systems Contact Cleaners

21. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 21 Vacuum Systems Cost effective Reliable Proven Efficiency 15 to 20 micron

22. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 22 Types of Vacuum Systems High Pressure, Low Volume Low Pressure, High Volume

23. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 23 Vacuum Systems High Pressure, Low Volume Traditional “High Suction” System High Static Pressure Requires a supported surface Idler roller Solid Surface Contact or Non-Contact

24. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 24 Vacuum Systems High Pressure, Low Volume Strict mounting requirements “KISS” touch contact brush system Rotary brush contact system Chad blade non-contact system Limited debris handling capacity 10 to 20 feet distance to collector

25. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 25 High Pressure, Low Volume

26. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 26 Vacuum Systems Low Pressure, High Volume

27. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 27 Vacuum Systems Low Pressure, High Volume Designed to move volumes of air Low static pressure Capable of supported or unsupported web installation Contact or Non-Contact Effective in non-contact applications

28. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 28 Vacuum Systems Low Pressure, High Volume Varied mounting options Over supported surface or open web Effective debris handling capabilities Capable of transporting debris distances Collection system remote mounting

29. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 29 Low Pressure, High Volume

30. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 30 Low Pressure, High Volume

31. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 31 VACUUM SYSTEM TESTS BEFORE/AFTER

32. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 32 Vacuum System Test Results

33. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 33 Vacuum System Test Results

34. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 34 Contact Cleaners Electronics industry origins Smaller particle removal Effective to 1 micron Nip configuration most effective Consistent surface contact Consistent control of Boundary Layer

35. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 35 Contact Cleaners Industrial usage capable Speed handling capabilities improved with ground “tacky rolls” Ground vs Cast rolls: geometry and balance <1,000 fpm systems: adhesive tape cleaning >1,000 fpm systems: computer controlled cleaning, 24/7.

36. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 36 Contact Cleaner Configuration Comparison

37. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 37

38. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 38 Contact Cleaner Test Results - 1 micron

39. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 39

40. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 40 ROI Return on Investment “How clean do you need to be?” >15 to 20 micron >1 micron

41. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 41 ROI Return on Investment How much does it cost you to be dirty?” Reduced productivity = $ Increased labor/maintenance cost = $ High production rejects = $ Customer returns = $

42. Jay Perry Simco Industrial Static Control www.cema-converting.org Page 42 “Typical ROI, regardless of the system chosen, is in months”
