According to the latest research data released by China Water Network on "China's Water Market Research Report (2012 Edition) - China's Water Industry Policy and Market Analysis" (hereinafter referred to as the "Report"), during the "12th Five-Year Plan" period, industrial wastewater treatment Investment demand will exceed 120 billion. During the “Twelfth Five-Year Plan†period, industrial wastewater treatment has become an area of ​​concern in the treatment of water pollution. According to data from the National Bureau of Statistics, the total industrial wastewater discharge in 2010 was 23.747 billion tons, accounting for 38.47% of the total national wastewater discharge. . The compliance rate of industrial wastewater discharge was 95.3%, which was 4.1% higher than that in 2005. From the perspective of emission standards, not only conventional pollutants are faced with further reductions, but the total amount of ammonia nitrogen is also on the agenda. With the continuous development of China's industrialization and urbanization level, the industrial wastewater will continue to be treated, and the water quality discharge standards will also become more and more stringent, and the environmental protection supervision policy will be further strengthened. In this context, the demand for investment in the industrial wastewater treatment market will further increase. According to the analysis of the "Report," during the "11th Five-Year Plan" period, the total investment for industrial wastewater treatment in the country reached 82.1 billion yuan, accounting for about 3.8% of the country's total investment in environmental pollution control. According to the “Twelfth Five-Year Plan†environmental protection plan, the total environmental protection investment demand during the “Twelfth Five-Year Plan†period is about 3.4 trillion yuan. If the same proportion is estimated, the investment demand in the national industrial wastewater treatment sector will reach 129 billion yuan from 2011 to 2015. yuan. Iron-based alloy powder is commonly used in plasma transfer arc welding (PTAW) due to its excellent mechanical properties and high resistance to corrosion and heat. This type of powder is typically composed of iron as the base metal, along with various alloying elements such as nickel, chromium, molybdenum, and tungsten.

The specific composition of the iron-based alloy powder may vary depending on the desired properties and application requirements. For example, adding nickel can increase the strength and toughness of the weld, while chromium enhances the corrosion resistance. Molybdenum and tungsten are often added to improve the high-temperature strength and creep resistance of the weld.
Iron-based alloy powders for PTAW are available in various particle sizes, typically ranging from a few micrometers to several hundred micrometers. The powder is usually fed into the plasma arc through a powder feeder, which ensures a controlled and consistent supply of powder during the welding process.
During PTAW, the powder is melted and deposited onto the workpiece, forming a weld bead. The high energy plasma arc provides the heat necessary to melt the powder and the base metal, creating a strong and durable weld joint.
Overall, iron-based alloy powder for plasma transfer arc welding offers excellent weldability, high mechanical properties, and resistance to corrosion and heat, making it suitable for a wide range of applications in industries such as aerospace, automotive, and power generation.
Investment Demand for Industrial Wastewater Treatment from 2011 to 2015 will reach 129 billion yuan
