A phosphogypsum ceramic nozzle and its manufacturing method

Abstract

The invention discloses a phosphogypsum ceramic nozzle which is characterized by being prepared from the following raw materials in parts by weight: 3-4 parts of waste high-voltage electric porcelain, 80-95 parts of silicon carbide, 2-3 parts of phosphogypsum, 4.2-5.4 parts of basalt, 3-5 parts of diatomite, 3-4 parts of waste glass powder, 1.5-2.5 parts of calcium carbonate, 10-14 parts of yttrium oxide, 0.4-0.7 part of lanthanum phosphate, 3-4 parts of pp short fibers, 4-6 parts of diethylene glycol, 5-7 parts of tartaric acid, 2.1-3.4 parts of sesbania gum, 6-8 parts of pentaerythritol triacrylate, 0.5-0.9 part of acetyl peroxide, 3-5 parts of an auxiliary and proper amount of water. The preparation method of the phosphogypsum ceramic nozzle is simple in formula, easy to operate and low in cost and adopts chemical industrial waste phosphogypsum, calcium carbonate and silicon carbide as main components, and other effective components are added into the raw materials. The prepared ceramic nozzle has performances of high hardness, abrasion resistance, good mechanical strength, uniform texture and the like.

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 phosphogypsum 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, radiatio...
