TESTING THE INTEGRITY OF GLOVEBOX

GLOVES FOR SUB-VIRAL SIZE DEFECTS

UTILIZING ELECTRON BEAMS

Introduction:  The Problem !
 
 

"….weakest link in the containment barrier".
 

"….the Achilles’ Heal".
 
 

Challenge: Resolve The Issue !
 

Solution: Integrity Testing Utilizing Electron
                   Beam Technology
 

Technology Application in Glove Manufacturing
 

Technology Application With-in Glovebox
 

Technology Application Out-side Glovebox
 
 
 

Water Leak Test (Fill the Product with Water)

Electrical Hydraulic Test (Submerge the Product in Water)

             Limitations:
 

Conformal Electrode Mandrel, Wet Test, Electrical Potential Applied, Short Circuit Indicator, Large Straight Holes Only (50 Microns Plus), No Anomalies, Water Surface Tension, Product Dried with Hot Air (Ozone)

Dry Test or Spark Test (Electrically Charged Brush)

             Limitations:
 

Direct Contact, 1.3 to 1.5 kV AC @ 60 Hz, Conformal Electrode Mandrel, Large Destructive Spark, Large Straight Holes Only (50 to 100 Microns Plus).

Capacitive Test (Submerge the Product in Water)

             Limitations:
 

Conformal Electrode Mandrel, Wet Test, Different Frequencies (Not Just DC or 60 Hz), Discovery of Holes, Blisters, and Bubbles, Repeatability and Calibration Difficult, Integral Measurement (Gray or Average Measurement), Product Dried with Hot Air (Ozone).

Statistical Testing (Destructive Test)

             Limitations:
 

Sample Finished Production, Product is Destroyed in Process, Not 100% Tested, Mathematical Prediction, Implied AQL Level with Acceptable "Rejects".

Oxygen Leak Test (Non-Destructive Test)

             Limitations:

Expensive, Limited to the Hand and FingerTips, Cumbersome, Uncomfortable Working Design, Time Consuming.

 

Electron Beam Technology: (Corona Beam or C-Beam)

Advantages:

Dry Test
Product Tested on Molding Mandrel (Providing
    Curing Is Not Required)
In-Line in Real-Time
Non-Contact
Based On Point-To-Point Effect
Griebel-Gormley Aperture Effect (Anomaly Acts as a "Point")
Cover Gas Creates a "Focal Area" (nitrogen)
C-Beam Self Seeking in Focal Area
C-Beam Follows a Tortuous Path
C-Beam Articulates to Find Its’ Potential
Finds "ALL ANOMALIES" (Sub-Viral Size Holes and Voids, Bubbles, Blisters, Contamination, Stress Fractures, Formulation Defects, Low Density Areas, Uncatalyzed or Unblended Resin, etc.)
Discrete Measurement (No Average)
Measures Electric Discharge (Volume of Electrons)
Constructive and Destructive Interference (Frequency Changes at Sensor)

C-Beam Applications: (Three Methodologies)

 1ST .  At Glove Manufacturing Facility

      In-Line with the Manufacturing Process
      (No Labor Cost with Handling)

      Testing is Final Step before Unloading

 2nd . Test Within the Glovebox

C-Beam Sensor is Located Inside the Glovebox above the Glove Port in Reach of Operator

Multiple Sensors at Each Port Location-Test At Will

3rd .  Test Outside of the Glovebox With the Glove
Inside-Out With a Hand-held Sensor Gun
 
 

Conclusion:

Glovebox Integrity Does Not Have To Be Compromised If C-Beam Technology Is Implemented  and EVERYONE PLAYS THEIR PART.
