This technology is an innovative achievement with independent property rights. It has been widely used in national construction projects in various industries such as petrochemical industry, chemical fiber, nuclear power, water supply, drainage, heating, ocean development, etc. It has been recognized by the majority of users and achieved significant economic benefits. The technical system is mainly composed of: first, coatings, which are B series melt-bonded epoxy powder coatings and polymer composite coatings; second, coating equipment, which are B pipeline coating production line; B special-shaped parts coating production line and pipe molding coating production line; third The process includes fast curing, slow curing and room temperature curing. The fourth is the coating technical specification. Based on the research results, the national standard B/ "Anti-corrosion coating of fusion bonded epoxy powder coating" was formulated. This heavy-duty corrosion protective coating, an innovative achievement with independent property rights, mainly has the following performance characteristics: strong bonding between the coating and the substrate; high mechanical strength of the coating itself, outstanding impact resistance; strong penetration resistance of the coating; chemical stability of the coating It has good properties and is resistant to acid, alkali and salt corrosion. The coating has low surface roughness and small friction with fluids. It can be used as an inner coating for drag reduction. The coating is non-toxic and meets food hygiene standards and can be used in the food industry. Single-layer sintered epoxy powder anti-corrosion steel pipe, B powder anti-corrosion steel pipe, reinforced anti-corrosion steel pipe, oil and gas special anti-corrosion steel pipe, etc. Welcome to call us for consultation and cooperation. B epoxy powder anti-corrosion B epoxy powder anti-corrosion structure is coated on the surface of the steel pipe using electrostatic spraying technology Epoxy powder forms a film in one go. The coating has the advantages of simple coating operation, no pollution, good impact resistance and bending resistance, and high temperature resistance. /Anti-corrosion/Anti-corrosion structure: The surface of the steel pipe is electrostatically sprayed with epoxy powder and laterally wrapped with adhesive and laterally wrapped with a polyethylene anti-corrosion layer. Combining the excellent properties of the three, it significantly improves the overall quality of the anti-corrosion pipeline. Resistant to chemical corrosion, cathodic stripping, and mechanical damage. Epoxy coal pitch anti-corrosion epoxy coal pitch anti-corrosion structure is an anti-corrosion coating made of epoxy resin + coal tar pitch + filler. Glass cloth is used as a reinforcing coating on the surface of the steel pipe to form an anti-corrosion layer. It is often used for anti-corrosion on the outer wall of the pipeline. The thickness is generally ~. Epoxy sintered powder anti-corrosion B/B high-density polyethylene jacket anti-corrosion structure is made of high-density polyethylene material wrapped on the outer surface of the steel pipe after the service life has expired. It has extremely high mechanical strength and excellent resistance. Corrosion properties can protect steel pipes from damage caused by external factors during transportation, installation and use. Antioxidants, UV stabilizers and carbon black should be added to the outer casing. The polyethylene outer casing is easy to age. If it is stored in the open air, it should be covered with a tarpaulin. The stacking place should be away from high heat and fire sources. After being made into anti-corrosion steel pipes, it is forbidden to be exposed to the sun or quenched. Otherwise, the polyethylene outer casing will easily crack and affect the product. performance and longevity. Epoxy powder dipping process Anti-corrosion epoxy powder has always been applied by electrostatic spraying process. Because the epoxy powder dipping process is plagued by adhesion problems, the epoxy powder dipping process has never been popularized.
The coating can also be machined as needed, and can be used on dynamic parts to enhance the wear resistance, cavitation resistance and erosion resistance of the parts, and improve the service life of the parts in harsh environments. It has been evaluated and tested in practical applications. , heavy corrosion protection technology has become increasingly mature, solving many corrosion problems that other protection technologies have failed to solve, and has made important contributions to the sustainable development of the national economy. It can be widely used in the following fields to protect buried pipelines such as long-distance transportation of oil, water, and gas. Protection of process pipelines and special-shaped parts from corrosive media such as acids, alkalis, salts, and ash. Heavy corrosion protection of pumps, valves, fans and other equipment. Corrosion protection of bellows compensators in heating and seawater pipelines. Anti-corrosion electrolysis of marine engineering and dock steel structures. Copper industry seed plate edge coating equipment and repair of damaged pipeline parts, long-distance buried pipeline repair. At present, it has been applied in the key project of seawater valves for naval vessels and seawater pipelines in the Shanghai Pudong natural gas pipeline anticorrosion project of the West-East Gas Pipeline. Experts believe that this series of coatings is widely used, has good use effects, long lifespan, and no environmental pollution. Its promotion and use in related industries will greatly reduce economic losses caused by corrosion and will definitely produce significant economic and social benefits.
