MATERIALS TEST LABORATORY

Transcription

1 MATERIALS TEST LABORATORY Fundamental component of Development and Marketing Strategy A Collection of dedicated Laboratories & Testing Cells World Class facility for testing and demonstration Simulate end use applications wherever possible Improve existing test methods and develop new methods Testing and Consulting for other Chesterton Divisions as well as joint research with customers.

2 Why is the Test Lab Important The Test Lab Is Used to: to You? Benchmark the Competition Assist in Product Development Support Manufacturing and QC Analyze Samples From the Field Pioneer a More Complete Understanding of Corrosion and Corrosion Protection. Matrix Technology Reinforcement Technology Interaction Between Matrix and Reinforcement Phases Process Technology

3 General Areas for Testing Mechanical/Physical properties Thermal properties Microscopy Thermo-Mechanical properties Chemical properties Corrosion resistance Other

4 Test Equipment Instron (Universal Tester) Video Microscopy Hydraulic Adhesion Tester Vapor Transmission Test Viscometer (Cone & Plate Rheometer) Goniometer Differential Scanning Calorimeter (DSC) Heat Deflection Temperature (HDT) Tester Chemical Resistance Testing Corrosion Chamber (Salt Fog) Corrocells Abrasion Slurry Tester Marine Environment Chambers (Fish Tanks)

5 Instron (Universal Tester) Mechanical Property Testing Compression Properties Tensile Properties Flexural Properties Slip coefficient testing Results are strain rate dependent Sample geometry also effects results

6 Instron with oven attachment Mechanical property testing at elevated temperatures Measures a material s mechanical response to temperature

7 Video Microscope

8 Video Microscopy 1x to 240x magnification Surface analysis Photographic capability

9 Hydraulic Adhesion Tester Portable test equipment Tensile pull off adhesion strength (minimize tangential shear) Other adhesion test methods under development

10 Vapor Permeation Cells Vapor transmission through a thin film under controlled temperature and humidity Film thickness = End use thickness 100% humidity on one side and 0% on other side Measure weight change of cell until equilibrium is reached

11 Viscometer/ Rheometer Rheological properties of polymers and composites Used to develop viscosity vs. temperature profiles Provides valuable data for spraying as well as other application methods Important for the S series of products

12 Goniometer Contact angle measured and surface energy calculated Used for development of foul release coatings Important property for hang up applications Directly related to fluid flow efficiency

13 Differential Scanning Calorimeter Measures sample s response to thermal energy input Determines Glass Transition temperature (Tg) Samples can be uncured (cure study evaluation), cured, or returned from the field Very small sample size needed

14 Heat Deflection Temperature Tester

15 HDT Test Deflection temperature under flexural load Samples heated at 2 C / min. Indicates the temperature at which a material bends under a given load Can be used to measure deflection vs. temperature

16 Chemical Resistance Testing

17 Chemical Attack Soak testing of sample coupons in various chemicals at various temperatures Monitor weight change and surface appearance Weight loss from leaching and weight gain from absorption/swelling Used for formulation screening and benchmarking

18 Corrosion Resistance Testing Corrosion Chamber (Salt Fog) Scored and unscored panels in 5% salt fog at 35 C (95 F) Extremely severe marine environment Very long test Measures a coating s resistance to underfilm corrosion

19 ASTM B 117 Salt Fog Evaluates a coating s resistance to underfilm corrosion.

20 Scored Salt Fog Panels (3000 hrs.) Tile Clad - Two Coats Tile Clad with Zinc Rich Primer Bitumastic 300-M

21 Assembled Corrocell

22 Corrocell Test Cell Tests Material s Resistance to Both Liquid and Vapor Phase Exposure Coated Test Panels Can Control and Test Variables: 1. Temperature 2. Cold Wall Effect 3. Chemical Meets: ASTM D 4398 NACE TM ANSI/ASTM C 868

23 Corrocell Panel After Test Corrosion of base metal after permeation Chemical load at elevated temperature Mechanical load (permeation) at elevated temperature Simulates real world conditions

24 Abrasion Slurry Tester Sliding abrasion under varying chemicals and slurry concentrations Test method under development

25 Marine Environment Chambers Salt water, Brackish water, Fresh water Foul release coatings for Nuclear Power Industry
