AFC‑7610 Organic Silicone Defoamer

AFC-7610 Organic Silicone Defoamer for Pulp & Paper Mill

AFC-7610 is a high-concentration, modified silicone defoamer engineered specifically for the demanding conditions of pulp and paper production. Backed by 20 years of manufacturing experience, Guanru Chem’s technical team designed this formula to deliver instant foam knock-down and long-lasting suppression in high-alkali and high-temperature systems.

Why is AFC-7610 the Preferred Choice for Paper Mills?

Zero Oil Spots Guarantee: Our advanced emulsification process ensures that AFC-7610 disperses perfectly in the pulp, eliminating the risk of oil spots, fish-eyes, or surface defects on the finished paper.

High Temperature & Alkali Stability: Unlike standard silicone defoamers, AFC-7610 remains stable and effective in black liquor systems and high-pH environments (up to pH 13).

Rapid De-aeration: It doesn't just kill surface foam; it penetrates the liquid to release entrained air, improving pulp drainage and machine speed.

Low Dosage, High Efficiency: Its high active content allows for significant cost savings, with effective results at concentrations as low as 100-500ppm.

Product Description

AFC-7610 can maintain good stability in industrial production, has excellent acid and alkali resistance, and maintains excellent defoaming and anti-foaming properties under acid, alkali, and high shear conditions. It exhibits excellent stability, particularly in high-temperature and strong-alkali systems.

Features of AFC-7610  Silicone Defoamer

• Long-lasting foam suppression in the pulping black liquor system.

• Not easy to produce stickies.

• Good stability under high temperature and strong alkali systems.

Application areas

As a leading industrial defoamer manufacturer, we recommend AFC-7610 for the following processes:

Pulp Washing & Screening: Controls vigorous foam in vacuum washers and pressure screens.

Black Liquor Recovery: Highly effective in the evaporation and concentration of black liquor.

Paper Machine Wet End: Ensures a smooth, air-free headbox flow for better sheet formation.

Silicone Defoamers vs. Non-Silicone Defoamers

In industrial production, foam control is a key factor affecting efficiency and quality. Silicone defoamers and non-silicone defoamers have significant performance differences and are suitable for different situations. This article analyzes the basic differences between the two, including chemical composition, performance advantages, and industries, to help you make an accurate decision.

FAQ

• Does AFC-7610 cause silicone spots on the final paper?

A: AFC-7610 is formulated with high-performance emulsifiers and is easily dispersed in pulp. When used at the recommended dosage, it leaves no residue.

• How does it compare to fatty alcohol defoamers?

While fatty alcohols are cheaper, AFC-7610 (Silicone-based) offers much higher temperature resistance and requires a significantly lower dosage to achieve the same or better results in black liquor.
