TREATMENT OF TOUGH INORGANIC FIBERS AND THEIR USE IN A MOUNTING MAT FOR EXHAUST GAS TREATMENT DEVICE

摘要

The method of treating tough inorganic fiber bundles includes opening a plurality of tough inorganic fiber bundles so that the tough inorganic fibers can be dispersed in a liquid slurry to accumulate a homogeneous fiber aggregate, wherein the tough inorganic fibers exceed 250 ml, Optionally has a crush precipitation volume greater than 450 ml. In addition, the method for treating tough inorganic fiber bundles comprises dispersing a plurality of tough inorganic fiber bundles in a slurry with a diluent of about 0.1% to about 2%, and optionally about 0.1% to about 1%, effective to accumulate homogeneous fiber aggregates. Including a step, the tough inorganic fibers have a crush settling volume of greater than 250 ml, optionally greater than 450 ml.
