AI Technical Summary
Existing water-based silicone defoamers are prone to stratification, sedimentation, and demulsification during long-term storage; they are also prone to clumping at low temperatures and to the growth of microorganisms under high temperature and humidity conditions. Furthermore, they have poor additive compatibility and unbalanced overall performance.
By employing a scientific formulation of silicone oil, filler microparticles, catalyst, polyether, emulsifier, viscosity modifier, pH modifier, preservative and bactericide, antifreeze and deionized water, and through high-temperature activation modification, multi-stage hot water phase inversion and gradient homogenization processes, the dosage of each component and preparation process parameters are optimized to construct an emulsion system with excellent compatibility.
This defoamer achieves long-term storage stability, low-temperature stability, and corrosion resistance. It has a fast defoaming speed, long-lasting foam suppression, and a wide range of applications. It solves the problems of poor stability and compatibility in existing technologies and significantly reduces stratification, sedimentation, demulsification, and microbial growth.
