Who knows about the situation of American Blue Company?

Their cleaning agents are homemade and passed off as imported (it’s unclear whether there are issues with the formulas). Red Blue in the United States permits emissions (although this is also allowed in the U.S.; it is not certified in China). This post was last edited by ybl118 on 2008-5-24 11:49]

Fosroc products from the United States are polymer composite repair materials developed by top chemical engineers and formulators from leading global chemical companies in state-of-the-art laboratories. They have been successfully used for many years by the most experienced application specialists in world-renowned companies, offering unique advantages in terms of corrosion resistance, cavitation resistance, wear resistance, impact resistance, and erosion resistance for industrial equipment. Foseco’s polymer composite repair materials in the United States come in 6 series; among them, the 2211/2212 metal repair and protection materials, as well as the 2222/2223/8510/8518 materials designed to resist corrosion, erosion, cavitation, and wear, have been successfully utilized in the production, maintenance, after-sales service, and development of new pumps. The 2211/2212 composite repair material not only possesses extremely high strength and comprehensive performance, but also excellent resistance to corrosion and chemical erosion. It features machinability, allowing it to repair various worn shafts, bushings, bearing housings, slides, various pipes, PVC pipes, as well as cracks in castings and steel components. It can also be used to refurbish worn or corroded pumps, pump cores, and valves. The 2222/2223/8510/8518 composite materials exhibit wear resistance in fluid environments that is no less than that of 316 stainless steel. They possess excellent resistance to impact, solid particles carried in fluids, cavitation, and bimetallic corrosion, as well as strong chemical resistance. For this reason, they have gained widespread recognition among users for repairing and protecting pumps, fan housings, and impellers that are damaged by corrosion or cavitation, as well as for repairing valves, turbine impellers, and guide vanes in hydroelectric stations. The 8500 series products have been approved by the U.S. Maritime Administration for use as protective coatings on rudders, propellers, and fairings. In various fields such as petroleum, machinery, chemicals, coal mining, metallurgy, power generation, and transportation, wherever there are equipment, maintenance issues arise. Compared with repair techniques such as thermal spraying, cladding, and electroplating, the use of Fosilene polymer composite materials for bonding and surface coating offers unique advantages. As companies gain a better understanding of this material technology, its application in equipment maintenance will bring greater economic benefits to them.

Haven’t heard of it. If anyone knows anything about it, please share

The waste liquid after cleaning can be discharged directly if there are no toxic substances in the heat exchange equipment; it meets all discharge standards, including those set by the United States.
