7. Professional FAQ on Calcium Hydroxide Technical Terms

Q1: What is the typical purity range required for industrial Calcium Hydroxide?

A: The standard industrial Calcium Hydroxide should have a Ca(OH)₂ content of ≥90%. Premium applications such as food processing and high-tech manufacturing often require purities between 95% and 98%, which Shijiazhuang Baifeng Mining Co.,Ltd can provide.

Q2: What particle size specifications are commonly demanded?

A: Most customers require D90 ≤ 45μm for optimal dispersion and reactivity, though certain uses such as construction or soil stabilization allow D90 up to 75μm.

Q3: How is Calcium Hydroxide typically packaged and stored?

A: It is usually supplied in 25kg, 40kg, or 1000kg bags, tightly sealed, and stored in cool, dry environments to prevent carbonation and moisture absorption.

Q4: What installation or handling standards should be observed?

A: Operators should follow standards like OSHA guidelines (ventilation, dust control, PPE usage) and national chemical safety protocols due to its alkalinity and dusting potential (OSHA).

Q5: What chemical compatibility does Calcium Hydroxide have?

A: It reacts vigorously with acids, with possible exothermic reactions. Avoid contact with strong oxidants, ammonium salts, and moisture.

Q6: Why is moisture content such a key metric?

A: Lower moisture improves shelf-life, flowability, and active reactivity. Baifeng’s product is controlled below 1.0% moisture, surpassing most industry standards.

Q7: How does whiteness impact end-product applications?

A: High whiteness (>93%) is essential for paper, food, and paint applications for better aesthetics and product consistency.
