In industrial production, the rust removal of steel plates has always been an important and difficult problem. Traditional rust removal methods are not only inefficient, but also polluting the environment. Today, let's discuss an efficient and environmentally friendly steel plate rust removal technology - ultra-high pressure water jet technology.
The importance of rust removal from steel plates
During the production and processing of steel plates, they are susceptible to oxidation and rust. Rust not only affects the appearance of the steel plate, but more importantly, it will reduce the strength and corrosion resistance of the steel plate, thus affecting the quality and service life of the product. Therefore, an effective rust removal process is essential to ensure the performance of the steel plate.
Ultra-high pressure water jet technology
Ultra-high pressure water jet technology is a method that uses a high-pressure pump to pressurize water to more than 1000MPa, and forms a high-speed and high-energy water jet through a specially designed nozzle to impact and peel off rust on the surface of the steel plate. This technique has the following characteristics:
Efficient: The ultra-high-pressure water jet quickly and thoroughly removes rust and oxide from the surface of the steel plate.
Environmental protection: The whole process does not need to use chemicals, does not produce hazardous waste, and has no pollution to the environment.
Non-destructive: The ultra-high pressure water jet does not cause damage to the steel plate itself, and does not affect the mechanical properties of the steel plate.
Application in steel plate rust removal
Rust removal process: ultra-high pressure water jet is sprayed to the surface of the steel plate through the nozzle, and the high-speed water jet peels off the rust and oxide layer from the surface of the steel plate under the action of impact.
Equipment configuration: The ultra-high pressure water jet rust removal system mainly includes high-pressure pumps, nozzles, control systems, water pipelines, etc. Depending on the size of the steel plate and the degree of corrosion, the pressure and flow rate of the water jet can be adjusted.
Key points of operation: The operator needs to master the operation skills of ultra-high pressure water jet equipment, and reasonably adjust the angle and distance of the water jet to ensure the effect of rust removal.
Advantages of ultra-high pressure water jet technology
High efficiency: Compared with traditional methods such as manual grinding and chemical cleaning, ultra-high pressure water jet technology has a faster rust removal speed and greatly improves production efficiency.
Low cost: Although the initial investment of ultra-high pressure water jet equipment is high, in the long run, its operating costs are low and it is easy to maintain.
Wide range of applications: Ultra-high pressure water jet technology is suitable for rust removal of steel plates of various specifications and materials, with high flexibility.
Safety and environmental protection: The ultra-high pressure water jet technology does not need to be exposed to harmful chemicals, which reduces safety risks and meets the requirements of green production.
Fields of application
Exploring the application of ultra-high pressure water jet technology in steel plate rust removal in various industries, we found that it not only improves work efficiency, but also ensures engineering quality and safety. Here are some of the specific applications of the technology in several key areas:
◆ Petrochemical industry
In the field of petrochemical and power generation equipment, the application of ultra-high pressure water jet technology not only ensures the stable operation of the equipment, but also improves the safety. For large-scale petrochemical equipment that is susceptible to oxidation and rust, rust removal is a necessary step before painting, and the environmental protection and low energy consumption characteristics of this technology have made it widely used in the petrochemical field.
◆ Ocean vessels
Ship construction: Steel plate is the core material of ship construction, and the rust removal treatment on its surface is essential to ensure the quality of the ship and prolong the service life. Ultra-high-pressure water jet technology plays an integral role in this process.
Ship maintenance: In the face of the challenges caused by seawater corrosion, ultra-high pressure water jet technology can effectively remove rust from corrosion-prone parts such as stern, bow and side of the ship to ensure the continuous operation of the ship.
◆ Construction work
Steel structure building: The derusting treatment of steel structure is essential for the safety and durability of the building. The application of ultra-high pressure water jet technology in this field avoids the inconvenience of traditional methods on the construction site.
Aluminum alloy formwork for concrete engineering: The cleaning and rust removal of aluminum alloy formwork not only improves the service life of the formwork, but also reduces the operating cost and provides efficient support for concrete engineering.
◆Road and bridge engineering
Steel bridge deck: In highway engineering, the quality of rust removal treatment of steel bridge deck directly affects the durability of bridge deck pavement and the service life of the bridge. The precise application of ultra-high pressure water jet technology ensures the effective play of the anti-corrosion layer.
Bridge concrete steel formwork: The rust removal treatment of steel formwork is an important link before the concrete pouring construction of the bridge, and the use of this technology ensures the treatment quality of the formwork base.
◆ Water conservancy projects
In the construction of water conservancy projects, the surface cleaning of steel formwork is indispensable. The application of ultra-high pressure water jet technology improves the cleaning efficiency and reduces the investment of manpower and material resources.
◆ Made of steel
In the steel production process, steel plate rust removal is a critical step in improving the quality and purity of steel. The use of ultra-high pressure water jet technology ensures the surface treatment of the steel before leaving the factory and enhances the market competitiveness of the product.
