Process for preparing sheet composites containing crystalline phosphate fibers |
摘要 |
Fibrous sheet composites are prepared by (a) forming an aqueous dispersion comprising asbestiform crystalline calcium M phosphate fibers wherein M is a metal cation selected from the group consisting of sodium and lithium, and mixtures thereof, auxiliary fibers, and a water insoluble organic polymeric binder; (b) distributing and draining the aqueous dispersion on a porous substrate to form a wet sheet-like solid phase or wet web; and (c) pressing and drying the wet web.
