Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a ceramic polymer lined composite pipeline processing method and its composite pipeline, which overcomes the problems caused by pouring wear-resistant materials in steel pipes, pasting ceramic patches or wear-resistant plastic sheets. The performance and the overall performance of the patch are not good, and the service life is short, especially for complex pipes with a diameter of less than 1m or curved pipes that cannot be manually constructed, so as to achieve the technical purpose of composite pipes with the characteristics of wear resistance, anti-corrosion, and long service life.

Embodiment 1

[0021] Make a composite pipe of φ118×9. Select φ118×5 seamless steel pipe, use 12×5×2 alumina ceramic sheet, use aluminum dihydrogen phosphate adhesive to bond the ceramic sheet to the rubber layer with a thickness of 2mm, and make it φ108×4mm For the hose whose inner layer is alumina ceramic sheet, the outer wall of the hose is evenly coated with aluminum dihydrogen phosphate adhesive, and then passed into the steel pipe, one end of the hose is sealed, and then the other end is fed with a pressure of 2.0MPa Nitrogen propped up the hose, and the constant pressure was maintained for 24 hours. After the rubber, alumina ceramics and steel pipe were fully bonded together, the pressure was removed to produce a composite pipe.

Embodiment 2

[0023] make 130×14 composite pipe. select A 130×2 seamless steel pipe is made of a 50×50×10 silicon carbide ceramic sheet, and the ceramic sheet is bonded to a nylon layer with a thickness of 2 mm by epoxy resin to make it 126×12mm hose whose inner layer is nylon, evenly coat the outer wall of the hose with epoxy resin adhesive, and then pass it into the steel pipe, 27 seal one end of the hose, and then pass it into the other end with a pressure of Nitrogen props up the hose, and the constant pressure is maintained for 24 hours. After the rubber, silicon carbide ceramics and steel pipe are fully bonded together, the composite pipe can be produced after the pressure is removed.

Embodiment 3

[0025] make 96×7 composite pipe, choose A 96×3 seamless steel pipe is made of a 12×5×2 silicon nitride ceramic sheet, and the ceramic sheet is bonded to a polyurethane layer with a thickness of 2mm by a phosphoric acid-copper oxide adhesive to make it 90×4mm hose whose inner layer is polyurethane, evenly coat the outer wall of the hose with phosphoric acid-copper oxide adhesive, and then pass it into the steel pipe, seal one end of the hose, and then pass it into the other end with a pressure of 2.0MPa The hose is propped up by nitrogen gas, and the constant pressure is maintained for 24 hours. After the rubber, silicon nitride ceramics and steel pipe are fully bonded together, the composite pipe can be obtained by removing the pressure.

Abstract

The invention relates to a method for processing a composite pipeline of a ceramic macromolecular lining and the composite pipeline thereof. In the method, a metal tube is used as a support material, and a wear-resistant corrosion-resistant high polymer material and a ceramic plate are used as a lining layer; the ceramic plate is adhered to the surface of the high polymer material by using an adhesive and is prepared into a hose; the outer surface of the hose is coated with the adhesive, the hose is connected to the metal tube, one end of the hose is sealed and high pressure gas is introduced from the other end of the hose, so that the hose is adhered to the metal tube under the action of pressure and the hose made of the ceramic and the high polymer material is supported and adhered to the inner wall of the metal tube by using the adhesive. The method overcomes the defects that complex pipelines such as pipelines with small inner diameter, bent pipelines and the like cannot be constructed; the composite pipeline has high strength, wear resistance and corrosion resistance by combining the metal, the high polymer material and the ceramic, can replace the metal pipeline, has long service life, and can be widely applied to deslagging and exhausting pipeline systems in the industries of metallurgy, mine, electric utility, chemicals and the like.

Description

technical field [0001] The invention relates to a technique in the field of composite materials, in particular to a processing method for a composite pipeline lined with a ceramic polymer lining and the composite pipeline. Background technique [0002] Friction and wear is a ubiquitous natural phenomenon. Friction consumes more than 1 / 3 of the primary energy, and wear is one of the three main ways of material and equipment damage and failure, causing losses equivalent to more than 2% of GDP. my country is the second largest energy consumer; however, energy consumption per unit of GDP is 2.6 times that of the United States, 4.0 times that of Germany, and 4.6 times that of Japan. my country has a lot of room for development in saving energy consumption and resources. At present, steel pipes are generally used in domestic and foreign cement plants, steel plants, power plants, petrochemical plants, mines, coal mines, etc. to transport ore powder, coal powder, slag powder, petr...
