A "5L Stainless Steel Defoamer Bucket Oil Free Vacuum Defoaming Bucket" describes a laboratory or pilot-scale unit that combines mechanical centrifugal defoaming with vacuum pressure to achieve ultra-efficient, contaminant-free foam removal, crucial for high-precision industries.
This machine is designed to remove air bubbles (defoaming/deaeration) from viscous liquids (e.g., resins, inks, pastes, epoxies) without introducing any oil contamination from pumps. It uses a two-stage process:
Centrifugal Defoaming: A high-speed rotating plate creates centrifugal force, spreading the material into a thin film and throwing heavier components outward. Bubbles, being lighter, are separated and rise to the surface where they burst.
Vacuum Defoaming: A vacuum pump lowers the pressure inside the chamber. This drastically reduces the volume of any remaining trapped air bubbles, causing them to expand, rise rapidly, and collapse.
The combination of these two methods is extremely effective for stubborn, fine bubbles in thick fluids.
Capacity: 5 Liters. This is a bench-top size, perfect for R&D, prototyping, and small-batch production.
Material: Stainless Steel (Grade 304 or 316). This ensures:
Corrosion resistance against chemicals.
Ease of cleaning and sterilization.
Durability and a long service life.
This machine is used in industries where eliminating micro-bubbles is critical to product performance and quality:
Electronics: Encapsulation resins, potting compounds, underfill materials, conductive inks, and pastes.
Optics & LEDs: Optical lenses, LED packaging epoxy, and adhesive films where bubbles cause light scattering or defects.
Printing & Coatings: High-value inks, pigments, and coatings for precision applications.
Medical & Pharmaceuticals: Silicon gels, medical adhesives, and bio-compatible pastes.
Advanced Materials & Research: Nanomaterial slurries, ceramic pastes, and composite materials.
High Efficiency: The dual centrifugal + vacuum action removes even the smallest micro-bubbles.
Zero Contamination: The oil-free vacuum ensures the product remains pure.
Consistent Quality: Produces bubble-free, homogeneous products, crucial for performance and yield.
Compact & User-Friendly: The 5L size is ideal for lab environments.
