Synthesis of Oxide Fibers Using a Fiber Drawing Machine

摘要

The Marksman Fiber Drawing Machine (Chemat Technology Inc., Northridge, CA) is a research scale, positive displacement, piston-type, fiber extruder. The machine was custom made to extrude various compositions of fibers from polymeric precursors specifically designed with sufficient flexibility to cover anticipated research requirements. It has a capacity of 10-150 grams, offers operational temperatures up to 500 degrees C, a 10-10,000 m/minute take- up capacity, and 2400 Watts heater capacity. It allows the continuous drawing of fiber while the diameter of the spinnerette hole can be designed to fit application requirements. Standard spinnerette orifice diameters of 200 nanometers, 150 nanometers, and 100 nanometers were supplied. In addition, an orifice diameter of 30 nanometers was custom made for research use. The machine for UIUC was custom made with an integrated high-temperature furnace to allow the fiber to be dried and sintered at elevated temperatures in three zones, up to 1,200 degrees C with programmable controls.
