Recently, the China National Intellectual Property Administration officially granted three utility model patents to Yunnan Gangfeng New Materials Co., Ltd., focusing on industrial environmental protection and production efficiency enhancement. This marks national recognition of the company’s innovative achievements in waste acid treatment, titanium dioxide production, and sand mill equipment.

The three authorized patents are:

A Recyclable Sand Mill for Titanium Dioxide Production

(Patent No. ZL202422858114.1)

A Cooling Tank Preventing Residual Titanium Dioxide Hydrolysis Slurry

(Patent No. ZL202423167612.8)

A Waste Acid Concentration Device Preventing Scaling and Blockage

(Patent No. ZL202423020362.5)

Gangfeng New Materials has strategically aligned its patent portfolio with two major directions — the extension of the titanium dioxide industry chain and the treatment of industrial by-products — fully consistent with its long-term focus on resource recycling and green chemical technologies.

The approval of these three utility model patents not only builds an intellectual property moat covering both equipment improvement and process optimization but also accelerates technological progress in the titanium dioxide and waste acid treatment sectors through innovation.

Looking ahead, Gangfeng New Materials will continue to increase R&D investment, targeting breakthroughs in key segments of the new materials industry chain. By transforming more innovative achievements into productivity, the company aims to inject new momentum into the industry’s green transition and the high-quality development of regional economies.
