RESEARCH ON HEATER-TENSION PADS AND HIGH TEMPERATURE HEATERS. PART I - EVALUATION OF HEATER-TENSION PADS AT 500 F

Abstract

Two hundred fourteen 120-volt 5-kilowatt per sq ft micro-film heaters for operation to 600 F were built for heater reliability studies and for use in heater-tension pad tests. This micro-film heater proved to be robust and sufficiently reliable FOR APPLICATIONS TO LARGE SCALE TESTING. The procedures for constructing 500 F, 20 psi heater-tension pads employing a silicone rubber and phenolic-epoxy adhesives were established. Endurance tests indicate a high degree of reliability. Success in building heater-tension pads utilizing a fluorinated elastomer Viton for operation at 600 F and 20 psi was delayed by difficulties in bonding to the Viton. However, the availability of thicker and sponged Viton suggests that this problem can now be solved. Tests made on the temperature distribution of honey-comb structures indicate that the desired degree of uniformity can be attained.
