Inorganic fiber webs and methods of making and using |
摘要 |
Gravity-laid inorganic fiber webs and methods of making and using are disclosed. The gravity-laying process comprises mechanically separating inorganic fibers and collecting the fibers as a web, and may comprise blending of multiple types of inorganic fibers and/or blending of inorganic particulate additives with the fibers. |

1. A method of making a gravity-laid inorganic fiber web, comprising:
introducing inorganic fibers into a forming chamber that comprises a plurality of fiber-separating rollers provided in at least one row within the forming chamber, and that comprises a moving endless belt screen; mechanically separating at least some of the inorganic fibers with the fiber-separating rollers; capturing any remaining agglomerates of the inorganic fibers by the moving endless belt screen and returning the captured agglomerates to the fiber-separating rollers to be mechanically separated by the fiber-separating rollers; collecting the mechanically separated inorganic fibers as a gravity-laid inorganic fiber mat; removing the gravity-laid inorganic fiber mat from the forming chamber; and, consolidating the gravity-laid inorganic fiber mat to form a gravity-laid inorganic fiber web. |
