The plant is located within the National Economic and Technological Development Zone in Xindeng Town, Fuyang District, Hangzhou
It leverages an existing production line for waste acid resource recovery to implement a comprehensive resource utilization project, supported by an in-house R&D laboratory. The facility sources its raw material from waste acid generated during the descaling process of ordinary carbon steel plates.
This waste acid has been legally classified as general industrial solid waste and meets the standards for resource recovery feedstock. Utilizing advanced and proven recovery technologies, the plant transforms iron-bearing waste acid into ultrafine tri-iron tetroxide (a ferrite material) and calcium chloride solution, with product quality meeting or exceeding relevant industry standards.
The company's main products include
- Iron oxide black (various grades such as 359, 368, and 378, used in industries including pigments, coatings, and inks);
- Zinc-iron yellow (a high-temperature resistant composite pigment suitable for plastics, coil coatings, etc.);
- Calcium chloride solution (used in sectors such as oil drilling, construction, refrigeration, and textile printing and dyeing);
- Calcium sulfate whiskers (high-strength, high-modulus functional materials suitable for reinforcing composite materials).
Product Application
The company's products are widely used in fields such as pigments and coatings (inks, architectural coatings, coil coatings, etc.), oil drilling and chemical dehydration, construction materials and early-strength agents, plastics and masterbatch coloring, wastewater treatment and advanced oxidation catalyst supports, and reinforcing fillers for composite materials.
