With the rapid development of science and technology, a large number of wear-resistant and corrosion-resistant pipelines are required in mining, metallurgy, coal, electric power and environmental protection industries. At present, in the process of material transportation, sand, gravel and mineral powder mainly rely on rubber pipes, and slurry transportation mainly relies on metal pipes. However, since materials or slurries are often corrosive in some industries, wear-resistant and corrosion-resistant pipeline materials are required to meet the needs of the market; and in material conveying systems and mineral grinding and separation equipment in these industries, All kinds of hoppers, silos, chutes, chutes, ball mills, cement mills, vertical mills and other parts are often prone to equipment damage and production accidents due to the strong impact and grinding of materials. In order to solve the above related problems, now Some main wear-resistant and corrosion-resistant pipes include cermet pipes and their composite materials.

Chinese patent CN201259030Y discloses a ceramic rubber and ceramic plastic wear-resistant composite pipe, which mainly includes a rubber layer and/or a plastic reinforcement layer on the inner or outer surface of the ceramic rubber composite pipe body; Surface or outer surface with metal or fiber reinforcement. The disadvantage is that the ceramic particles are compounded in the rubber, and the bonding between the ceramic and the rubber is poor. Due to the aging of the rubber during use, it is easy to cause the ceramic particles to fall off and reduce the service life of the pipeline. Chinese patent CN101788087A discloses a preparation method of a ceramic rubber wear-resistant pipe, which is mainly to arrange the ceramic sheets neatly on the adhesive tape, and then stick it on the raw adhesive tape with pressure, then wind it on the cylindrical abrasive tool, and finally put the Put it into the vulcanization tank for desulfurization to obtain the product. Its disadvantage is that the service life of the pipeline depends on the tape, and the tape is easily invalidated in a corrosive solution, causing the ceramic sheets to fall off. Chinese patent CN202623425U discloses a wear-resistant ceramic rubber liner, which mainly includes a rubber plate. The inner surface of the rubber plate is compounded with a wear-resistant ceramic sheet, and a strong magnetic magnet is embedded in the outer surface. The wear-resistant lining is improved by the strong magnetic magnet. The bond strength between the plate and the chute plate. The disadvantage is that due to the effect of strong magnetic magnets on the crushed materials, it is easy to accumulate and accumulate on the surface of the ceramic sheet, which affects the working efficiency of the equipment, and it is not convenient to replace the wear-resistant ceramic sheet that has failed. Chinese patent CN104646121A discloses a wear-resistant liner, which mainly includes the fixed surface of the liner and the working surface of the liner. The working surface of the liner is provided with a ceramic layer. Its advantage is that it can improve the wear resistance of the liner. The chip is relatively brittle and prone to failure. After the working surface fails, it will not be replaced, which reduces its service life and efficiency.
