High-Quality Precipitated Calcium Carbonate (PCC) from China Suppliers | Reliable Factory for Industrial Additives
Product Description
Improving slag fluidity and stability, helps remove impurities.
During high-temperature smelting processes, precipitated calcium carbonate helps promote slag formation and improves the fluidity and stability of the slag. This not only helps remove impurities but also effectively improves the efficiency and output of the smelting furnace. It can adjust the acidity and alkalinity of the furnace charge, helping to maintain balance during the smelting process, ensuring more stable reaction conditions, and enhancing the controllability of the production process.
Improving the hardness and strength of glass, enhance its compressive and bending resistance.
The addition of precipitated calcium carbonate can increase the hardness and strength of glass, making it more resistant to compression and bending. This not only improves the durability of the glass but also reduces the probability of breakage. An appropriate amount of precipitated calcium carbonate can improve the optical properties of glass, increasing its transparency and gloss. Especially in the manufacture of high-transparency glass, it helps control the quality of the finished product and meets the requirements of different applications.
