Alumina ceramic structural parts are a product with a very wide range of uses. However, in the actual appointment process, the alumina ceramic structural parts will inevitably be worn. There are many factors that cause structural parts to wear. These can be effectively prevented from these aspects. Wear of alumina ceramic structural parts.

Alumina ceramics is a ceramic material with alumina (Al2O3) as the main body, used for thick film integrated circuits. Alumina ceramics have good conductivity, mechanical strength and high temperature resistance. It should be noted that ultrasonic cleaning is required. Alumina ceramics is a kind of ceramics with a wide range of uses. Because of its superior performance, it has become more and more widely used in modern society to meet the needs of daily use and special performance.

The alumina ceramic​ lining board above 99 is the best among the ceramic lining boards, and the unit price is extremely high, but its physical properties are also excellent, with high hardness and good toughness. It is especially suitable for parts with severe impact and wear.

Alumina ceramic cylinder, alumina ceramic gasket, 95 alumina ceramic base, 99 alumina ceramic insulating tube, 99 or more alumina ceramic insulating tube, ceramic injection molding parts, alumina ceramic discs, ceramic parts, alumina ceramics Plate punching, alumina ceramic parts blind hole addition, alumina ceramic disc grooving, alumina ceramics above 99 are heated up and down, alumina positioning seat, alumina ceramic ring, 99 alumina ceramic coil frame, alumina ceramic circle Disc.

As a widely used material in ceramics, alumina ceramics presents the following development trends along with the development of the entire industry: (1) The level of technical equipment will be rapidly improved: the development of computer technology and digital control technology has promoted the technological progress and rapid development of the ceramic material industry, such as automatic control of continuous sintering kilns, high-power and large-capacity grinding equipment, and high-performance powder manufacturing Complete sets of equipment such as granular equipment and other net pressure forming equipment have beneficially promoted the improvement of the overall level of the industry, and at the same time, the production efficiency and product quality have also been significantly improved;

Alumina ceramics is an industrial ceramic with high hardness, which can only be processed by diamond grinding. It is made of bauxite and can be processed by injection molding, pressing, isostatic pressing, sliding castings and other methods.

High temperature resistance: Alumina ceramics can be used in the atmosphere up to 1650°C or 2900°F, and in the vacuum environment of 2000°C or 3600°F. At 1000 degrees Celsius, it maintains 50% of its tensile strength at room temperature. Although the strength of metals is weakened in high temperature environments, alumina ceramics retain their strength when they return to normal temperatures and remain unchanged. Alumina ceramics have high electrical resistivity and can reduce thermal shock, and increased purity will increase their electrical resistivity. Alumina ceramics become a perfect insulating material due to its dielectric level, etc., and current cannot pass through them.

1. In terms of machinery, the bending strength of Al2O3 porcelain sintered products can reach 250Mpa, and the hot-pressed products can reach 500Mpa. The Mohs hardness of Alumina ceramic can reach 9, and it has excellent wear resistance, so it is widely used in the manufacture of tools, ball valves, grinding wheels, ceramic nails, bearings, etc. Among them, Al2O3 ceramic tools and industrial valves are widely used.

Because alumina ceramics have relatively unique properties and have been valued in the market, the main thing is that they have also attracted the development and research of researchers, so that it can be used in air pollution control, the possibility of molten metal filtration, etc. However, many existing problems still need to be resolved in a timely and effective manner.

Alumina ceramic parts are used in many industrial production occasions, which fully shows that ceramic parts have many superior properties compared to other materials, and they will become popular in the industry. At present, alumina ceramics can be mainly used for protection tubes and insulating tubes of temperature measuring instruments, thermocouple thermometers; at the same time, it can also be used in furnace tubes of industrial resistance furnaces, experimental electric furnaces, and heat treatment furnaces.
