Fuzzy Comprehensive Evaluation of Corrosion-Resistant Properties of PTFE Compounded Fibers

PTFE compounded fiber is the raw material of the industrial fabrics which have been applied for separating particles from industrial exhaust under harsh industrial conditions such as the oxidant and high temperature environments. It is a decision process with multiple factor analysis to select an optimal PTFE compounded fiber with good corrosion-resistant property among several samples. The study applied Analytic Hierarchy Process and a new fuzzy comprehensive evaluation method to evaluate the corrosion-resistant properties of four tested PTFE compounded fibers, which are PTFE fiber with chemical coat and PTFE fiber without chemical coat and PTFE/glass compounded fibers with membrane laminating and PTFE/glass compounded fibers with chemical coat. The results show that the compounded technology of PTFE/glass fibers and chemical coating can all improve the corrosion-resistant properties of the industrial fabrics against the oxidant and high temperature. It also can be concluded that the new fuzzy comprehensive evaluation method have advantages in the selection of the optimal one among many PTFE compounded fiber samples.
