1. Top 5 Customer Concerns About Solid (Powder) Defoamers

How to select the right product?

  • Based on pH: Use diatomite carriers for acidic systems; silica carriers are recommended for alkaline systems.

  • By temperature requirements: Standard type (<150°C), high-temperature type (150-220°C), ultra-high-temperature type (>220°C).

  • Solubility considerations: Hydrophilic-modified products for water-soluble systems; hydrophobic types for oil-based systems.

Why is defoaming performance unsatisfactory?

  • Possible causes:

    • Particle size mismatch (sieve testing recommended).

    • Insufficient dosage (optimal amount should be determined through small-scale testing).

    • Poor dispersion (pre-mixing process is advised).

How to control costs?

  • Chemi-Tech's solid (powder) defoamer series enables low dosage (0.05-0.3%).

  • Long-lasting formulations reduce the need for frequent reapplication.

  • Cost-optimized formulations are available.

Does it affect product performance?

  • Surface modification technology prevents gloss reduction.

  • Strict control of impurities (e.g., heavy metals).

  • Compatibility testing services provided.

What precautions should be taken during use?

  • Storage: Moisture-proof, light-resistant, sealed.

  • Addition: Recommended in batches.

  • Equipment: Prevent pipeline clogging.
