玻璃纤维抄取密封垫片的制备及配方优化

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

将经过表面处理的玻璃纤维代替石棉纤维,采用胶乳抄取工艺制备了不同配方的密封垫片,测试了其压缩率、回弹率、拉伸强度、密度,采用多元回归方程研究了垫片配方与其性能的关系,并通过多目标优化函数对垫片配方进行了优化。结果表明:在相同的制备工艺下,垫片配方中各组分的含量对垫片性能的影响较大;随着玻璃纤维含量的增加,垫片的压缩率逐渐增加,回弹率、拉伸强度、密度逐渐减小;采用fgoalattain函数对垫片配方中的组分进行多目标优化后,垫片性能的实测值与优化目标值较接近,垫片的综合性能较好。

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.
