Problems solved by technology

[0002] Nozzles will be worn for a long time. At present, the materials used for nozzles include aluminum alloy materials, ceramics, etc. Aluminum alloy materials have poor wear resistance and need to be replaced frequently, resulting in high cost. Cold and heat stimulation, poor acid and alkali resistance, so it is necessary to research ceramic materials with excellent wear resistance, high hardness, good toughness, vibration resistance, heat resistance, corrosion resistance, etc., to reduce costs

Abstract

The invention discloses a diamond-micropowder-containing ceramic for a nozzle. The diamond-micropowder-containing ceramic is prepared from the following raw materials in parts by weight: 2-3 parts of strontium carbonate, 1-2 parts of boric acid, 13-17 parts of aluminum nitride, 1-2 parts of P2O5, 32-40 parts of Al2O3, 1-2 parts of K2O, 3-4 parts of diamond micropowder, 60-68 parts of silicon carbide, 1-2 parts of bamboo charcoal micropowder, a proper amount of deionized water, 3-4 parts of tetraethyl orthosilicate, a proper amount of ethanol and 4-6 parts of adjuvant. The ceramic disclosed by the invention is extremely high in wear resistance, high in hardness and not easy to break; when the ceramic is used for producing the nozzle, the service life of the nozzle is 3-4 times as long as that of a nozzle made of an aluminum alloy material, so that the cost is reduced, and the diamond-micropowder-containing ceramic is suitable for large-scale industrial production; and by using the adjuvant, the surface smoothness, wear resistance and heat resistance of the ceramic can be improved.

Description

technical field [0001] The invention relates to the field of ceramic materials, in particular to a ceramic for nozzles containing diamond micropowder and a preparation method thereof. Background technique [0002] The nozzle needs to be worn for a long time. At present, the materials used for the nozzle include aluminum alloy materials, ceramics, etc. The aluminum alloy materials have poor wear resistance and need to be replaced frequently, and the cost is high. Cold and heat stimulation, poor acid and alkali resistance, so it is necessary to study ceramic materials with excellent wear resistance, high hardness, good toughness, vibration resistance, heat resistance, corrosion resistance and other properties to reduce costs. SUMMARY OF THE INVENTION [0003] The object of the present invention is to provide a kind of ceramics for nozzles containing diamond micropowder and preparation method thereof, the ceramics have extremely high wear resistance, high hardness, and are no...
