carbon fiber undercoating comprises composite material, and composite material is made up of component A and B component, in component A, and carbon fiber powder 70-80kg, silicon carbide 40-60kg, aluminium oxide 95-120kg, zirconium oxide 30-40kg; In B component, glue 150-190kg, promoter 150-190kg.
carbon fiber undercoating comprises composite material, and composite material is made up of component A and B component, in component A, and carbon fiber powder 70-80kg, silicon carbide 40-60kg, aluminium oxide 105-110kg, zirconium oxide 30-40kg; In B component, glue 160-180kg, promoter 160-180kg.
meaning of the present invention is: the present invention is corrosion-resistant, wear-resisting, intensity is large, high temperature resistant, the life-span is long; The stable chemical nature of carbon fibre material, does not react with the chemical substance such as acid-alkali salt, has anti-high-alkali, peracid, high salt, and the ability of anti-various chemical corrosion and rugged environment change is strong, and high temperature resistance, antifatigue, excellent durability.Thus the component such as oil pipe, oil storage tank after reinforcing with carbon fibre material liner has good corrosion resistance, ageing resistance and durability.
carbon fibre material intensity is generally 6 ~ 10 times of steel, tensile strength 3200-4000mpa, and Young's modulus and steel are in the same horizontal line and slightly improve.Due to the physical and mechanical property of its excellence, reinforcing the structure such as oil storage tank, oil pipe, repair, the feature of its high strength, high-modulus can be utilized to improve shear-carrying capacity and the encapsulation of component in reinforcement process, improve its stress performance, reach not only anticorrosion but also efficient object of reinforcing.
because carbon fibre material is a kind of flexible material, so this anticorrosion, the petroleum industry component such as oil pipe and oil storage tank that liner, reinforcement technique can be conveniently used in various structure shape is anticorrosion, and not change structure shape and do not affect constructional appearance.Meanwhile, because its cohesiveencess is extremely strong, the component surface such as oil pipe, oil storage tank can be attached to securely, therefore, there is good creep resistant, wear-resistant, anti-seismic performance.
carbon fibre material quality is light and thickness is thin, and the components such as the oil pipe after reinforcing and repairing, oil storage tank, substantially do not increase deadweight and the size of original structure, do not increase structural load, do not affect oil pipe lifting rate, need not change sucker rod, pump specification.
embodiment: embodiment 1, carbon fiber undercoating comprise composite material, and composite material is made up of component A and B component, in component A, carbon fiber powder 50-100kg, silicon carbide 30-70kg, aluminium oxide 65-150kg, zirconium oxide 20-50kg; In B component, glue 100-240kg, promoter 100-240kg; Its preparation method is, the first step puts the raw material of component A in container mixing and stirring; Second step lapping machine grinds, and fineness reaches 200-400 order; 3rd step is heated 120-200 degree; 4th step adds glue in B component and promoter, continues to be uniformly mixed; Tube wall eliminates rust by the 5th step, reaches SA2.5 grade standard; Then with spray gun, pure carbon powder is sprayed onto face, oil pipe inner surface layer, first pass thickness is 50-75 micron, after 5-10 hour, with spray gun, composite material is sprayed onto pure carbon powder top second time, thickness 80-120 micron; After 7-12 hour, with spray gun, composite material is sprayed onto the top of composite material for the 3rd time, thickness 80-120 micron; After 7-12 hour, the 4th time is top layer, with spray gun, composite material is sprayed onto the outside of composite material, thickness 50-75 micron; After 7-12 hour, with spray gun, component A is sprayed onto the outside on top layer for the 5th time, thickness 40-60 micron, 110-150 degree of heating; 6th step solidification, becomes finished product in curing time 3-5 days.
