Main Applications
1. Detergent Industry
Used as filler in powdered detergents to improve fluidity and adjust concentration.
2. Glass Manufacturing
Acts as a fining agent to remove small air bubbles and improve glass transparency.
3. Textile & Dyeing Industry
Used as leveling agent in dyeing processes to ensure uniform color distribution.
4. Chemical Industry
Applied as raw material in the production of sodium sulfide, sodium silicate, and other chemicals.
5. Paper Industry
Used in kraft pulping process as part of the chemical recovery system.
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.
