Zirconia ceramic nozzle for color sorters and manufacturing method thereof

The invention discloses a zirconia ceramic nozzle for color sorters. The zirconia ceramic nozzle for the color sorters is characterized by being prepared from the following raw materials in parts by weight: 75-80 parts of silicon carbide, 6-9 parts of zirconia, 1-3 parts of steel fibers, 2-3 parts of magnesite, 6-9 parts of calcium silicate slag, 0.4-0.7 part of chalk powder, 1.1-1.6 part of cellulose ether, 4-7 parts of glycerol, 13-15 parts of organic molybdenum, 0.7-1.2 parts of aramid fiber, 25-35 parts of cerium dioxide, 0.3-0.5 part of 1-hexadecanesulfonic acid sodium salt, 0.3-0.6 part of sodium hexadecanesulfonate, 0.1-0.3 part of sodium tripolyphosphate, 3-4 parts of auxiliaries and appropriate amount of water. By adding a plurality of effective constituents, the prepared ceramic nozzle has favorable corrosion resistance and abrasion resistance, a duct is small, good in internal finish degree of the duct is good, the spray effect is ideal; a three-dimensional complicated nozzle can be manufactured; and the manufacturing method is simple and the cost is low.
