Chongqing Dazhong Anti-corrosion Joint-stock Co., Ltd.

Basic Information of the Company

Chongqing Dazhong Anti-corrosion Co., Ltd. (hereinafter referred to as the "Company") was established in 1993 and restructured into a joint-stock company in 2012. Its predecessor was Chongqing Dazhong Anti-corrosion Engineering Co., Ltd. Starting from 2005, the Company shifted from general anti-corrosion to specializing in special corrosion control mechanism research, material research, standard research, corrosion monitoring research, corrosion industry research, and corrosion construction research.

Since 2007, the Company has been committed to flue gas desulfurization chimney corrosion control in the field of energy conservation and emission reduction. After 8 years, it has developed 15 national invention patents for chimney corrosion control, participated in the compilation and served as chief editor of three chimney corrosion specifications, and as the national representative, served as chief editor of the national specification "Technical Specification for Anti-corrosion Operation of Chimneys after Desulfurization Coated with Liquid Fluororubber" GB/T31819-2015, as well as six enterprise specifications, covering all areas from anti-corrosion design, materials, to construction processes, and has formed its own intellectual property "Fluororubber FRP Structural Layer Chimney Anti-corrosion Technology", which has been successfully applied to corrosion control of desulfurization chimneys in China's energy conservation and emission reduction field.

In order to enhance the technological competitiveness of the fluororubber FRP structural layer chimney anti-corrosion technology, improve the comprehensive performance of various products in this technology system, reduce the cost of the technology system, and comprehensively apply it to China's major petrochemical, petroleum, metallurgical, power, chemical, aerospace, marine and other fields with "excellent technology, good products, and reasonable prices", the Company plans to rely on its special corrosion control resources and be supported by national science and technology development and industrial platforms to jointly cooperate in "dedicating to the development and industrialization of industrial special corrosion control technology", establish a long-term and comprehensive scientific and technological partnership, and jointly promote the scientific and technological progress and industrialization of special corrosion control in China.
