A high-toughness ceramic nozzle and its manufacturing method

Abstract

The invention discloses a high-toughness ceramic nozzle which is characterized in that the nozzle is manufactured from the following raw materials, by weight: 65-75 parts of aluminum oxide, 2.3-3.7 parts of sillimanite, 1-3 parts of dolomite, 5-8 parts of kyanite, 3-6 parts of pearl powder, 3-5 parts of calcium carbide slurry, 1-2 parts of pre-gelatinized starch, 2-3 parts of PVC powder, 18-30 parts of silicon dioxide, 1.1-1.5 parts of quicklime, 3-4 parts of maleic anhydride, 2-3 parts of triethanolamine, 4-6 parts of fatty alcohol polyoxyethylene ether, 0.4-0.8 parts of oxidized paraffin soap, 3-4 parts of an auxiliary agent, and balance of water. The manufacturing method provided by the invention has the advantages of simple process and reasonable design. With various organic and inorganic additives, product technical indicators are effectively improved. The manufactured ceramic nozzle has the advantages of high toughness, good seismic performance, good fatigue resistance, good wear resistance, and the like.

Description

technical field [0001] The invention relates to a preparation process of a ceramic nozzle, which belongs to the technical field of nozzle molding, in particular to a high-toughness 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, wear resistance, ra...
