How to Solve Defoaming Challenges in Pigment Grinding? Chemi Tech Offers Breakthrough Solutions

In the world of color, every drop of pigment carries precise hue and gloss. Yet during production, foam generated by high-speed grinding becomes an invisible threat to quality—these stubborn bubbles not only reduce grinding efficiency but also create defects on the final product surface.

Mr. Wang, a technical director at a coating enterprise, once struggled with this issue. His team encountered persistent foam when developing high-concentration water-based pigments, where traditional defoamers failed to maintain effectiveness during grinding. Foam recurrence led to a 15% productivity drop and customer complaints about product appearance.

The turning point came through technical exchange with Chemi Tech. Our engineers identified that foam originated from intense shear between grinding media and resins. We recommended KM-220 series defoamer, which utilizes polyether-modified silicone composite technology. Its hydrophobic groups rapidly spread on foam surfaces while hydrophilic segments penetrate liquid films to disrupt surface tension equilibrium.

Field tests showed that adding 0.3% KM-220 reduced foam height to below 2mm within 30 seconds, with stability maintained throughout grinding. Notably, the additive caused no fisheyes or craters while improving color development. The team ultimately achieved 22% higher grinding efficiency and unprecedented product qualification rates.

Chemi Tech's defoaming technology stems from deep research in fluid dynamics. By simulating turbulent flow fields in grinding environments, we optimize the stability of defoaming molecules under high-pressure shear, ensuring both immediate foam breaking and sustained foam suppression. This technical balance proves crucial for quality improvement in production.

Today, this defoamer has become standard equipment in numerous pigment production lines. It not only resolves foam challenges but also creates continuous value through process optimization. In the pursuit of perfect color, Chemi Tech remains your trusted innovation partner.
