Donghe Building Materials is a specialized company focused on the resource utilization and export of fluorogypsum, and has been deeply involved in the field of fluorochemical by-products for many years.
Produced from industrial waste residue of anhydrous sodium bisulfate production through fine processing, this product features high yield, high purity, and stable quality. Our company has established a quality management system in accordance with the ISO 9001:2008 international quality management standard. It is widely used in building materials, chemical industry, agriculture, and other fields.
Fluorogypsum, a resource utilization product derived from fluorochemical solid waste, features outstanding cost-effectiveness after professional treatment. It can act as a cement retarder to boost strength, ameliorate alkaline soil for agricultural production, and be applied to mine and subgrade filling, reconciling environmental protection with engineering safety and catering to multi-scenario high-value utilization requirements.

| CaSO₄ | ≥93% |
| SO₃ | 54% |
| Moisture | ≤1% |
Through standardized processing and systematic quality control, the product exhibits stable composition and consistent batch quality, making it suitable for large-scale industrial and engineering applications.
Fineness, moisture content, activity indicators, and setting characteristics can be adjusted according to application requirements, adapting to different processes and project standards.
Utilizing professional defluorination, desulfurization, and drying processes, the product boasts a high calcium sulfate content and controlled impurities, meeting the requirements for building materials and industrial raw materials.
It demonstrates stable and reliable performance in applications such as cement retardation, roadbed filling, mine backfilling, precast components, and gypsum products.
Derived from the resource utilization of industrial by-products, it reduces the pressure on natural gypsum mining and aligns with the principles of circular economy and low-carbon development.
Based on the project type (building materials, road base, backfill, chemical industry, or soil improvement), define the target performance indicators, including fineness, moisture content, activity index, and setting characteristics requirements.
Select the appropriate particle size range (200–400 mesh optional), moisture content control standard (≤1%), and modification scheme to meet different process or construction conditions.
When used in cement, precast components, or road base materials, it is recommended to conduct small-scale trials first to determine the optimal dosage and process parameters before proceeding to large-scale application.
Store in a dry, ventilated environment, avoiding prolonged exposure to moisture; use moisture-proof packaging or storage conditions to maintain stable performance.
