Product Overview
LH-1827, LH-1829, and LH-1831 are high carbon alcohol defoamers designed for industrial applications. LH-1827 is specifically formulated for paper making processes, while LH-1829 and LH-1831 are engineered for the construction industry.
Defoaming Mechanism
High carbon alcohols consist of long-chain alcohols with numerous carbon atoms that form stable interfacial active agent molecular layers in water. The defoaming process involves three key mechanisms:
- Rapid diffusion to foam surfaces to reduce surface tension and destabilize foam films
- Penetration into foam membranes to disrupt structural integrity
- Formation of protective surface films to prevent new foam generation
