NOZZLE FOR FORMATION OF CHEMICAL THREAD AND FIBER FROM SOLUTION

摘要

This invention makes it possible to make a nozzle that excludes possibility of its material sticking to the cutting instrument in the process of making ideal in shape calibration aperture with small diameter, this promotes increase of the term of operation of the nozzle, stability of the process of formation and the quality of the thread and fiber obtained without deterioration of the corrosion stability of the nozzle. The problem is solved due to that the nozzle is made of zirconium alloy with addition of nitrogen, silicon, iron, molybdenum.
