Dowsil ACP-3056 Defoamer

DOWSIL ACP-3056 is a high-efficiency silicone defoamer engineered for pulp black liquor, combining siloxane fluid with a fine silica suspension (100% active) to boost defoaming performance. It maintains stability across pH 2–12 and temperatures ≤150°C, rapidly collapsing micron-level foam (≤10 sec) with a dynamic surface tension of 25 mN/m and providing 8+ hours of foam suppression. Its silica-enhanced technology accelerates foam film drainage, improving pulp washing efficiency by 20%–30%, and it complies with FDA 21 CFR 176.210 for safe use in kraft/sulfite pulping.

Product Information of Dowsil  ACP-3056 Defoamer

  1. Synergistic Defoaming: Silica-siloxane combination achieves >95% foam elimination, especially effective in high-solids black liquor (e.g., pine/eucalyptus pulp).

  2. Harsh Condition Resistance: Tolerates strong acid/alkali (pH 2–12) and high shear (≥5000 rpm) during pulp cooking and bleaching stages.

  3. Long Shelf Life: 360-day stability without stratification, usable in storage temperatures ranging from -20°C to 50°C.

Areas of Application of Dowsil  ACP-3056 Defoamer

  1. Chemical Pulping: Controls black liquor foam in kraft pulping (0.05%–0.2% dosage) to minimize fiber loss.

  2. Pulp Bleaching: Enhances uniformity of H₂O₂ bleaching and improves pulp brightness.

  3. Wastewater Treatment: Reduces foam in high-COD effluent aeration tanks of pulp facilities.
