Preparation and Formula Optimization of Glass Fiber Sealing Gasket by Beater-Addition Process

Glass fiber with surface treatment was substituted for asbestos fiber, and then sealing gaskets with different formulas were prepared by beater-addition process. The compressibility, recovery, tensile strength and density of the sealing gaskets were tested. The multiple linear regression was used to study the correlation between the performance and the gasket formula. The gasket formula was optimized by multi-objective optimization function. The results show that the content of components in gasket formula had a great influence on the performance of gaskets. With the increase of the content of glass fiber in the gasket formula, the compressibility increased gradually and recovery, tensile strength and density decreased gradually. The tested values of performance were relatively close to the optimal target values after the components of gasket formula were multi-objective optimized by fgoalattain function, and the gasket had relatively good performance after optimization.
