Method and apparatus for the measurement of cell size in a foam structure |
摘要 |
A method and apparatus are provided to continuously monitor and measure the average size of individual foam cells contained in a foam structure, such as polystyrene foam for example, as it is being fabricated. Such an arrangement permits the prompt adjustment of process conditions and/or the concentration of nucleating agents in the extrusion system in the event the size of the individual cells in the foam structure varies from a preselected standard.
