[0002] Since ceramic nozzles were introduced into China in the 1990s, the materials have been continuously improved and updated, gradually developing from oxide ceramics to nitride ceramics and carbide ceramics, but the production technology and preparation methods are backward, resulting in the existence of ceramic nozzles in the prior art. Many defects, such as low hardness, poor wear resistance, weak anti-corrosion and anti-erosion ability, low ductility, etc.

Abstract
The invention discloses an alumina / zirconia composite ceramic nozzle, which is characterized in that it is made of the following raw materials in parts by weight: alumina 65-80, zirconia 32-45, aluminum magnesium spinel 4-8, Rutile 5‑8, Paraffin 1‑2, Cobalt Sulphate 0.1‑0.3, Soft Soil 3‑4, Hard Soil 2‑3, Clay 4.1‑5.7, Nylon 12 0.6‑0.9, Palm Oil 0.2‑0.4, Monoglyceride 6‑ 9. Ethylene glycol monobutyl ether 4-8, polyurethane resin emulsion 8-12, auxiliary agent 3-4, and appropriate amount of water; the preparation process of the present invention is simple, the yield is high, and the price is low, and the prepared ceramic nozzle has good ductility, Good wear resistance, strong corrosion resistance, high tensile strength, long service life, meet the various needs of different color sorters, and high color sorting efficiency.
Description
technical field [0001] The invention relates to a ceramic nozzle preparation process, which belongs to the technical field of nozzle molding, and in particular to an aluminum oxide / zirconia composite ceramic nozzle and a manufacturing method thereof. Background technique [0002] Since ceramic nozzles were introduced into China in the 1990s, the materials have been continuously improved and updated, gradually developing from oxide ceramics to nitride ceramics and carbide ceramics, but the production technology and preparation methods are backward, resulting in the existence of ceramic nozzles in the prior art. There are many defects, such as low hardness, poor wear resistance, weak anti-corrosion and anti-erosion ability, and low ductility. In order to overcome the shortcomings of the existing technology, it is necessary to improve the existing ceramic nozzle production technology, so as to produce ceramics with low cost, multiple functions, flame retardancy, high hardness, ...
