Expert FAQ on Shell Powder Professional Terms
Q1: What is the primary material composition of Shell Powder?
A: Shell Powder is predominantly composed of calcium carbonate (CaCO3), usually ≥96%, with trace minerals and a small amount of organic matrix.
Q2: Which mesh size should be selected for advanced coating applications?
A: For high-grade paints and coatings, 1000 to 2000 mesh Shell Powder is recommended for improved smoothness, dispersibility, and opacity.
Q3: Are there any recognized standard test methods for Shell Powder quality?
A: Yes. Quality is typically evaluated using ISO 3262 for fillers, with typical tests including whiteness, CaCO
3 purity, moisture, and sieve residue (source:
ISO).
Q4: How is Shell Powder's oil absorption index relevant to polymers and plastics processing?
A: Oil absorption (≤25g/100g) affects mixing, extrusion, and final composite density. Lower oil absorption enables higher filler loading, improving properties while maintaining processability.
Q5: Can Shell Powder be used in food-grade or pharma products?
A: Only Shell Powder processed to food/pharma standards, with stringent purity and low heavy metals, is suitable. Always request food-grade certification and safety data.
Q6: What are the environmental impacts and regulatory standards regarding Shell Powder?
A: Shell Powder is bio-derived and low in toxicity. Main environmental standards reference REACH (
ECHA) and regional material safety protocols for mining and processing.
Q7: How can bulk Shell Powder be stored to prevent caking and moisture gain?
A: Store in sealed, moisture-proof, and clean environments, avoiding direct sunlight. Use original packaging or industrial PE liners for best results.
