Numerical Simulation on the Production of Glass Fiber Filter Product and Uniformity Improved on Cross-Direction
Journal of Physics: Conference Series(2020)
摘要
Abstract Glass fiber felt is produced by flame blowing process, but in the traditional flame blowing process, the uniform of product is affected by the airflow. When glass fiber through the air flow jet into the diffuser duct and reach to the web curtain, it is difficult to diffuse the width of the product needs. Researches show that, the size and shape of diffuser duct is critical to the movement of the glass fiber suspension in the duct, eventually the width and density distribution at the web curtain. In this paper, numerical analysis with experiment-based boundary conditions were used to the redesigned diffuser duct. The redesigned duct was built and produced, the product uniformity on cross-direction was tested and it has a good agreement with simulation analysis results. Through the redesign of the diffuser duct, improved the fabric weigh of the product in the cross-direction, get a more uniform product.
