A-43 Studies on Stainless Steel Piping System with High Durability : (Part 8) Test results for residual chlorine for promoting durable synthetic rubber

Abstract

To evaluate the durability test, a dumbbell test piece made of synthetic rubber in general, the concentration of residual chlorine test solution was adjusted, will be held immersion. 1) The amount of black powder deposition, processing time will be high density, are now rank 05 rating. 2) Changes in hardness and tensile and elongation, the material is different. 3) The processing time will be high levels of residual chlorine contained in the test solution, and voids and cracks. 4) The percentage of residual antioxidant, showed different trends depending on the material.
