Display of Sanxin’s Imported Thermal Spray Equipment: American Import—PRAXAIR JP8000 Supersonic Spraying Equipment PRAXAIR JP8000 Computer Operation Interface British Metallisation Spraying Equipment American Miller Plasma Spraying Equipment The JP8000 Supersonic Spraying System Produced by American Praxair—Features: The JP8000 spraying system is currently the world’s most advanced thermal spray equipment. Its spray gun power can reach up to 250 kW, with a flame temperature of 2,800°C and a combustion chamber pressure of up to 120 × 6.89 kPa. The powder particle velocity can reach 1,200 m/s, making it the only spraying equipment capable of producing compressive stress coatings. Coatings applied using this equipment exhibit high density, excellent bonding performance, low oxidation, and superior quality compared to Jet-kote coatings. The JP-8000TM HP/HVOF® system is the “next-generation” version of the earlier JP-5000®. It is our new, ultra-high-performance HVOF system featuring advanced control, extremely high productivity, and unique coating quality. Thanks to a series of exciting new features, the JP-8000TM boasts a more user-friendly interface than its predecessor. Improvements include the 8100 CORONA gas/fuel management system based on a sophisticated PLC and closed-loop control, providing more precise flame control, increasing equipment uptime, enhancing coating reproducibility, and improving final coating quality. Since its launch, the JP8000TMHP/HVOF® has gained widespread acclaim and recognition within the thermal spray community, achieving near-monopoly status in industries such as steel, corrugated roller manufacturing, and valve production. In 2011 alone, sales in the Chinese market exceeded thirty units, with particularly outstanding success in the valve industry in the Yangtze River Delta region. The JP8000TM has almost become synonymous with valve spraying. “The JP-8000TM is the next-generation system in the evolution of HVOF technology, featuring simpler operation, closed-loop control, and a modular drawer-style design.” The new JP-8000TM system represents a revolution in high-quality HVOF coating technology. To ensure perfection, Praxair Surface Technologies designed the JP-8000TM console around two primary goals: operator/system safety and ease of use. The JP-8000TM adopts separate fuel, gas, and electrical components, with high/low flow control and pressure switches that trigger alarms and shut down the system if operations exceed specified limits. The intuitive graphical user interface (GUI) “touchscreen” simplifies parameter setting and monitoring, ensuring consistent coating characteristics at all times. As an option, the GUI touchscreen can be detached from the electronic and gas/fuel/water module drawer unit and installed remotely. The key benefits of the JP-8000TM’s high particle velocity are its dense coatings and low oxide content. Density is achieved through tightly packed, uniform particle deposition, while low oxide content results from lower particle temperatures and shorter residence times in the flame. These features are especially beneficial in applications requiring highly wear-resistant, hard coatings and clean, dense coatings resistant to corrosion. System Advantages: The JP-8000TM system consists of the 8100 CORONA console, a standard 5220 spray gun, a 1264 powder feeder, all necessary spray gun hoses, and an operating manual. The 8100 CORONA Console: The 8100 is a fully automatic, closed-loop control console equipped with an easy-to-read and follow “touchscreen” graphical user interface (GUI). Operators simply select a process recipe from memory and press the “Run” button on the screen. Process engineers can easily develop and store new recipes using the “Development” screen. The touchscreen makes the console interface extremely user-friendly. To operate the system, operators must first log in. Different levels of protection can be set to prevent unauthorized users from accessing the coating development, process recipe, start-up, or maintenance screens. The application menu screen includes numerous options, such as imperial and metric units, powder feeder settings, reports, and maintenance schedules. The maintenance schedule screen is used to create maintenance schedules for spray guns, consoles, and powder feeders. The development mode screen is used for developing spray parameters. Similar to the control panel screen, parameters can be adjusted during the spraying process. Parameters can be easily transferred to the process recipe screen with a single touch. The process recipe screen is used to select existing parameters or re-enter new ones. The control panel screen displays all data that operators must monitor during the spraying process. Parameters are displayed but cannot be adjusted. The 8100 module circuit is designed as independent drawers, allowing easy removal for repair and maintenance. If necessary, a drawer module can be removed and replaced with a new one in a very short time, minimizing downtime. Thanks to precise control of oxygen and fuel flow, the JP-8000TM delivers high-quality, reproducible coatings. Oxygen flow is controlled by a mass flow meter (MFM) and gas proportioning valve loop. Fuel flow is controlled by the turbine wheel and variable-speed motor of the oil pump. Both loops are closed-loop controlled, providing unique control over the spraying process. Ultimately, the console can produce coatings that meet the requirements of both simple and extreme application conditions. The 8100 model is designed for safe operation and economical use of liquid fuels such as kerosene. Liquid fuels are easier and safer to handle compared to volatile gaseous fuels like hydrogen, propane/propylene, or natural gas. Kerosene is also cheaper than most other HVOF gas fuels. H.C.

Undertaking on-site construction of lithium-ion battery industry equipment, plasma cladding coatings, and nano-ceramic coatings.

Guangzhou Sanxin Company utilizes American Miller plasma cladding equipment and technology to perform on-site cladding of nano-ceramic coatings, which are suitable for hopper, screw, and ribbon mixing and conveying systems in the lithium-ion new energy industry.

HVOF Supersonic Flame Process: In supersonic flame spraying, oxygen and aviation kerosene are mixed in a premixing system and then burned in a high-pressure combustion chamber. The resulting flame jet, combined with high-pressure air passing through a Laval nozzle, generates a high-temperature, high-velocity flame stream that heats metal-ceramic powders to a semi-molten state.
