Experimental Research on the Performance of PSA and other Fiber Filter

Abstract:

The paper presents the comparative test among the high temperature resistant filter (such as PSA fiber, PMIA fiber, PI fiber) of the bag filter about their heat resistance and the corrosion resistance. The research test the breaking strength, the breaking elongation and the molecular structure of those fiber. Experiments show that the breaking strength of the PSA increase slightly under the high temperature up to 250°C,while the breaking strength of the PMIA fiber decrease 75.26% and the breaking strength of PI fiber decrease 65.57%. After being soaked in the sulfuric acid solution for 96 hours, the strength retentions of PSA, PMIA-1 and PMIA-2 are 42%, 18.85% and 46.71%. The result of testing by FTIR shows that the amide bond of the PSA fiber fracture and generate phenolics and carboxylic acid after the chemical treatment, which is the main reason why the fiber strength of PSA decrease after the acid and alkaline corrosion.
