[{"type":"text","content":"GMG Reaches Major Milestones in THERMAL-XR(R) Test WorkBrisbane, Queensland, Australia--(Newsfile Corp. - October 23, 2024) - Graphene Manufacturing Group Ltd. (TSXV: GMG) (\"GMG\" or the \"Company\") is pleased to provide a technical update on the commercialisation progress of THERMAL-XR® Powered by GMG Graphene.PRODUCT TECHNICAL UPDATETHERMAL-XR® has now successfully passed 15,000 hours for corrosion protection under a salt sea spray industry standard test (ASTM B117) in a third-party laboratory in the US as seen in Figure 1. The Company believes that THERMAL-XR® is one of the longest lasting corrosion protection coatings available on the market. The testing will continue, and further reports will be updated by the Company.Figure 1: THERMAL-XR® Coating Corrosion Test Results After 15,000 Salt Sea Spray Hours (ATM B117)To view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/8082/227525_ecd3ffa9c41478c4_001full.jpgGMG can now accurately model and calculate the heat transfer rate expected from THERMAL-XR®, as compared to bare (uncoated) Aluminium, within 1% of actual results. This was reviewed and verified by the University of Queensland. Figure 2 shows the simulation model used to calculate the heat transfer coefficients of bare aluminium, versus THERMAL-XR® coated aluminium, on the test rig that GMG built and operated to obtain the experimental data. The test was conducted at a temperature of approximately 100 degree Celsius.Figure 2: Estimation of Heat Transfer of THERMAL-XR® coated aluminium versus bare aluminiumTo view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/8082/227525_gmg_figure2.jpgThrough this work, as shown in Figure 3, the Company has demonstrated that THERMAL-XR® provides approximately 8.6 times more radiative heat transfer than bare aluminium, due to its thermal radiation (passing of heat in wave forms) capabilities. THERMAL-XR® has been calculated to provide 8.15 W/m2K (Watts per metre squared Kelvin degrees), or approximately 1.44 Btu/hr ft2 F (British thermal units per hour foot squared Fahrenheit degrees), of heat transfer when applied properly on top of bare aluminium, as compared to 0.95 W/m2K or 0.17 Btu/hr ft2 for bare aluminium.Figure 3: Thermal Radiation calculations of THERMA...
