Precision alumina ceramic sheet is also called precision alumina ceramic lining, high alumina lining, precision alumina ceramic patch, precision alumina lining, etc. So what is the difference between it and ordinary ceramics?

Precise alumina ceramic plate, precision alumina ceramic plate Features: First, the hardness is large, its Rockwell hardness can reach HRA80-90; its wear resistance is very good, wear resistance can be higher than manganese steel and high chromium cast iron , Can extend the service life of the equipment by more than ten times; In addition, the precision alumina ceramic sheet is very light, and its density is 3.65g / cm, which can greatly reduce the load on the device; the precision alumina ceramic sheet is firmly bonded on the device 2, Good heat resistance, can be run at 350 ° C for a long time without aging.

What is the difference between precision alumina ceramics and ordinary ceramics?

Why does the precision alumina ceramic plate have such a name? In fact, it is very simple. That is, some components of precision alumina are added to the ordinary ceramic plate ingredients, so the name is also special. The name of this ingredient is clearly marked so that people can better understand the difference between precision alumina ceramics and ordinary ceramics, so that they can better understand the properties of these different ceramic materials. , So that people can be very helpful, so that when you use these different materials, you can more effectively distinguish.

Why is the alumina component specifically added to the ceramic sheet? What is the difference between such a precision alumina ceramic sheet and ordinary ceramics, and what are their different performances? After adding such a precision alumina component, the hardness of the ceramic sheet has been greatly improved, especially this precision alumina ceramic sheet is currently the highest lubricity material, so it is used in the production of many industrial equipment , Has become the best and most practical material, and now it has been fully applied.

Precision alumina ceramic sheet

The most critical point is that compared with ordinary ceramics, precision alumina ceramics are very different in composition and manufacturing process. Ordinary ceramics are prepared through raw material preparation, blank forming and kiln firing. These three processes are completed, and most of the precision alumina ceramic sheets are manufactured by powder sintering technology.

95 alumina precision ceramic is a kind of alumina precision ceramic. According to the content of alumina in the product can be divided into 99 alumina, 95 alumina and so on. The following introduces 95 alumina precision ceramics by Kezhong Precision Ceramics.

95 alumina precision ceramic skeleton

Alumina precision ceramics are divided into 75 porcelain (75%), 92 porcelain (92%), 95 porcelain (95%), 96 porcelain (96%), 97 porcelain (97%), 99 porcelain (99 %) And 995 porcelain (99.5%) and 997 porcelain (99.7%).

Most domestic manufacturers currently produce 95% alumina precision ceramic products. At present, the products have a trend of high content development.

95 alumina precision ceramic is alumina-based material, which has good chemical resistance and molten metal resistance, high temperature resistance, good smoothness, thermal stability, small thermal expansion coefficient, good thermal conductivity, and mechanical strength. Large, high insulation strength, hardness is the same as corundum, wear resistance is comparable to super hard alloy.
  It can be used for bio-precision ceramics, electronic devices such as high-voltage switch shell insulation materials, mechanical parts such as seal ring valve parts, wear-resistant materials such as wear-resistant precision ceramic balls and rods, high-temperature devices such as high-temperature liquid delivery pipes, etc.

Washing is required for washing. Superior performance, more and more widely used to meet the needs of daily use and special performance.

95 alumina precision ceramic parts

Widely used in lighting appliances, electric heating appliances, petrochemicals, machinery, textiles, automobiles and other industries, the specifications can be customized according to customer needs.

But 95 alumina porcelain is mainly used as corrosion-resistant and wear-resistant parts. In addition, 95 alumina precision ceramic materials perform well. In terms of mechanical properties, mechanical properties refer to the ability of a material to not be damaged under the action of mechanical forces. Generally, tensile strength, flexural strength, and compressive strength are divided according to the direction of the force, the direction of the force, and the point of the force.
  The tensile strength of 95 alumina precision ceramics is generally above 160Mpa, which is usually greater than the best sealing strength.
