Do You Know The Processing Technology And Characteristics Of Zirconia Ceramic Tubes?

Do you know the processing technology and characteristics of zirconia ceramic tubes? With the continuous development and progress of industrial technology, zirconia ceramic tubes are widely used in various fields. The reason why zirconia ceramic tubes can be widely used is necessarily related to the performance characteristics of zirconia ceramics itself.   Zirconia ceramic is a material with high resistance to crack propagation. He has a high coefficient of thermal expansion, so it is often used to make metallized ceramics. Zirconia is a very good ceramic material, it has two outstanding properties of low thermal conductivity and high strength. Zirconia ceramics are widely used, can be used as wire forming molds, can be used as auxiliary materials in welding processes, and are often the best choice for insulating rings in high temperature environments.    The molding methods of ceramics include dry pressing, isostatic pressing, and injection molding. The zirconia ceramic tube is generally formed by isostatic pressing, which has good strength and is convenient for handling and direct machining. In addition, the isotropic density of the green body is uniform, the stress in the green body is small, the defects such as cracking and delamination of the green body are reduced, and the deformation of the sintered product is small.   Zirconia wear-resistant ceramic pipe has excellent wear resistance, high temperature resistance, mechanical and thermal shock resistance, corrosion resistance, smooth inner wall and easy installation, so zirconia ceramic pipe is especially suitable for material conveying equipment with severe wear and erosion, Equipment protection casing, etc.

What Is A Ceramic Wear-resistant Pipe?

Ceramic wear-resistant pipes mainly play a role in connecting equipment and equipment, transporting materials from one equipment to another, equipment for transporting gas, liquid or fluid with solid particles.   The difference between the ceramic wear-resistant pipe and the ordinary pipe is that the ceramic wear-resistant pipe will have a corundum ceramic lining inside the ordinary pipe by pasting, welding or isostatic pressing technology, as the anti-wear layer of the ceramic wear-resistant pipe to protect the outside. The steel pipe is not directly worn and corroded by the material, which greatly prolongs the service life of the pipe.    The ceramic lining of ceramic wear-resistant pipes can choose alumina wear-resistant ceramics or silicon carbide wear-resistant ceramics. Compared with alumina wear-resistant ceramics, silicon carbide wear-resistant ceramics have better wear resistance and higher hardness. Longer life, and silicon carbide wear-resistant ceramics are high-temperature resistant ceramics, which can operate effectively for a long time in high-temperature environments, and are suitable for use in high-temperature working conditions.   At present, alumina ceramics are widely used as lining materials for ceramic wear-resistant pipes. From the perspective of actual use, the service lives of wear-resistant ceramics of the same specification are sorted by length. Ceramic pipe, stick-type wear-resistant ceramic pipe, although the service life of stick-type wear-resistant ceramic pipe ranks third, but it is still about ten times that of ordinary steel pipe, and the process is simple and the cost is low, so the stick-type ceramic wear-resistant pipe is still At present, it is widely used in wear-resistant pipes with high cost performance.

What Are The Applications Of Wear-resistant Ceramic Sheets in Ash Removal Pipelines?

The wear-resistant ceramic sheet can be directly lined with high wear-resistant alumina ceramics in metal pipes, with its high cost performance, high hardness, good wear resistance, high temperature oxidation resistance, good corrosion resistance, powder erosion resistance, particle impact resistance and Known for its high temperature resistance, it has been widely used in thermal power, steel, heat, cement, tempering, mining, chemical industry, machinery, etc.   Wear-resistant ceramic sheets have a good application in ash removal pipelines. The shell of the ash removal pipe is generally made of Q235 material and lined with alumina ceramics. Its main function is to offset the scouring and wear of the mixed air flow, which can reduce its damage and prevent the mixed air flow from leaking due to wear and tear, thereby causing certain pollution to the environment, and now the use of wear-resistant ceramic sheets can be effective. to solve this problem.   It can avoid the leakage of the mixed gas due to damage, and then cause certain environmental pollution to the environment. Now the use of wear-resistant ceramic linings can effectively solve this problem and prolong the service life of the pipeline. The reason why the wear-resistant ceramic sheet has such an effect is that the wear-resistant ceramic sheet has the ability of high temperature resistance, wear resistance, corrosion resistance, shock resistance, thermal expansion and contraction resistance.   The wear-resistant ceramic sheet is pasted with professional ceramic sheet glue, so that it can be firmly bonded to the inner wall of the equipment without falling off. It has good heat resistance and can operate for a long time at 350 ℃ without aging.

Application Of Wear-resistant Ceramic Tube

Because the tube has wear resistance, corrosion resistance and heat resistance, it can be widely used in electric power, metallurgy, mining, coal, chemical industries and other industries as conveying sand, stone, coal powder, ash, aluminum liquid and other abrasive particulate materials And corrosive media, it is an ideal wear-resistant pipeline. Application in metallurgy and power industry Metallurgy and power industries need to consume a lot of metal pipelines every year to transport coal powder, ash, mud, lime gypsum slurry, etc. The use of ceramic composite pipes to replace other pipes has the characteristics of high wear resistance, long life, easy installation, and significant economic benefits. Through Shandong Liaocheng Changrun Thermal Power Plant, Liaocheng Zhonghua Power Plant, Beijing Beixin Building Materials Group, Henan Hebi Power Plant, Gansu Pingliang Power Plant, Taiyuan Coal Preparation Plant, Hunan Shimen Power Plant, Hebei Jinniu Energy Co., Ltd. Gequan Coal Preparation Plant, Xingtai Coal Preparation Plant In industrial operation, its operating life is ten times or even dozens of times longer than that of steel pipes. Application in mining and coal industry (1) Mines: Mine filling, ore concentrate and tailings transportation cause serious wear on pipelines. The service life of ore powder transportation pipelines used in the past, such as Panzhihua and Daye Mine, is less than one year. Changing to this pipe can increase the service life. About 5 times. (2) Coal: Coal preparation and long-distance pipeline transportation generally adopt wet transportation. The transportation pipe is required to be both wear-resistant and corrosion-resistant. The pipe can be used as a long-life transportation pipe with considerable economic benefits.
