Corrosion-resistant ceramic nozzle and manufacturing method thereof

Abstract

The invention discloses a corrosion-resistant ceramic nozzle. The corrosion-resistant ceramic nozzle is characterized by being prepared from the following raw materials in parts by weight: 1-2 parts of andalusite, 4-8 parts of halloysite, 2.6-3.9 parts of actinolite, 2.1-3.4 parts of nine-eye stone shale, 1.2-1.5 parts of pitchstone, 0.5-0.8 part of dextrin, 0.2-0.4 part of sodium sulfate, 24-37 parts of zinc oxide, 13-15 parts of manganese dioxide, 1.3-1.6 parts of anhydrous citric acid, 65-75 parts of nano silicon carbide micropowder, 3-4 parts of milled wood lignin, 12-14 parts of butyl acrylate, 11-15 parts of naphthenic oil, 3-4 parts of additives and a proper amount of water. A preparation method of the corrosion-resistant ceramic nozzle is simple, convenient to operate and low in cost; the prepared ceramic nozzle has the advantages of excellent abrasion resistance, high chemical corrosion resistance and high mechanical strength.

Description

technical field [0001] The invention relates to a ceramic nozzle preparation process, which belongs to the technical field of nozzle molding, in particular to a corrosion-resistant 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...
