These products are not only listed in the key areas of future energy-saving and environmental protection equipment development in the country but are also encouraged and supported by national policies. Sannai Environmental Protection has demonstrated a leading position in both domestic and international markets, becoming a key force in leading the industry's green transformation and technological innovation.
   Breaking the foreign monopoly on vinyl resin integral casting electrolytic cell technology
   Sannai Environmental Protection, since its establishment on June 27, 1997, has been committed to providing comprehensive electrolytic system solutions for the non-ferrous metal smelting industry. The company's main products and services include vinyl resin integral casting electrolytic cells, complete electrolytic systems, and supporting integrated electrolysis/electrodeposition process services. Among them, the vinyl resin integral casting electrolytic cell is the company's core product, which can be divided into various types such as copper electrolytic cells, zinc electrolytic cells, nickel electrolytic cells, and manganese electrolytic cells, according to different application fields. In addition, Sannai Environmental Protection also produces large-scale environmental protection equipment such as nitrogen oxide waste gas treatment systems.

As the first domestic enterprise to pass the scientific and technological achievement appraisal of the China Nonferrous Metals Industry Association for the new type of vinyl resin integral casting electrolytic cell, Sannai Environmental Protection has taken the lead in launching a comprehensive solution in the electrolytic cell field, breaking the international technology monopoly and setting a new industry benchmark. As a core equipment in the non-ferrous metal smelting process, the electrolytic cell's development trend is clearly inclined towards vinyl resin integral casting electrolytic cells. This type of electrolytic cell shows significant advantages in corrosion resistance, environmental performance, and service life, and has become the replacement trend for traditional electrolytic cells. In fact, foreign companies began more than 20 years ago to gradually eliminate traditional electrolytic cells and fully adopt vinyl resin integral casting electrolytic cells.

However, for a long time, vinyl resin integral casting electrolytic cell technology has been monopolized by foreign companies. Globally, the main professional manufacturers of vinyl resin electrolytic cells include the American CTI company and the Chilean ANCORTECMIN company; therefore, international market competition is mainly concentrated between these two companies. 。

However, due to the technological blockade of foreign enterprises and the high cost of international transportation, the application of vinyl resin electrolytic cells in China has been limited, and most enterprises are still using traditional steel-reinforced concrete fiberglass electrolytic cells.

Through years of efforts, Sannai Environmental Protection has successfully independently developed vinyl resin integral casting electrolytic cells and complete electrolytic systems with independent intellectual property rights, thereby breaking the monopoly of foreign companies in this technology. This has not only contributed to the healthy development of China's non-ferrous metal industry but also marks Sannai Environmental Protection's leading position in the industry's technological and equipment development.

In terms of technological research and development, Sannai Environmental Protection continues to explore cutting-edge technologies in the industry and has established a research and development model that mainly relies on independent research and development within the company and supplements it with external cooperative research and development. This model has not only driven the continuous growth of the company's main business but has also accumulated rich external research and development resources for the enterprise, including industry experts and downstream customers. 。

In addition, Sannai Environmental Protection has also developed a unique nickel electrodeposition process technology, which solves the problems of serious acid mist pollution, low grade rate of electro-nickel products, and low single electrolytic cell capacity in traditional processes, achieving energy saving and emission reduction and improving the product grade rate. At the same time, the company has also made important breakthroughs in copper electrolysis technology, with the output of each electrolytic cell increasing by approximately 20%. The successful application of these technologies has not only improved the company's competitiveness but has also contributed to the green development of the non-ferrous metal smelting industry.

Currently, Sannai Environmental Protection has obtained 79 patent authorizations, including 19 invention patents.
