Aluminum nitride-based ceramic nozzle and manufacturing method thereof
The invention discloses an aluminum nitride-based ceramic nozzle. The aluminum nitride-based ceramic nozzle is prepared from 75-80 parts by weight of aluminum nitride, 2.6-3.8 parts by weight of sapphire, 1-3 parts by weight of alumina-magnesia spinel, 3.3-4.5 parts by weight of flint, 4-6 parts by weight of fluorite tailings, 3-5 parts by weight of kaolin, 4.1-5.6 parts by weight of bentonite, 20-30 parts by weight of cobalt oxide, 5-7 parts by weight of straw ash, 1.5-2.8 parts by weight of polypropylene fibers, 4-7 parts by weight of hydroxypropyl methyl cellulose, 3-6 parts by weight of turpentine, 7-13 parts by weight of methyl methacrylate, 6-11 parts by weight of acrylic acid, 2-4 parts by weight of an auxiliary agent and a proper amount of water. The preparation method of the aluminum nitride-based ceramic nozzle improves the prior art and the formula, improves thermal shock resistance, washing resistance and toughness of the nozzle, reduces nozzle deformation and improves a material anti-deformation capability. The aluminum nitride-based ceramic nozzle has high density, excellent wear resistance, low plugging possibility and a long service life.
