Why Must Microbubbles in Materials Be Eliminated?
Residual micro‑bubbles degrade end‑product quality directly
LED Consumer Electronics IndustryBubbles in LED epoxy encapsulation reduce luminous efficiency, shift color temperature and even produce black spots in severe cases. Vacuum defoaming expands and releases bubbles under negative pressure. Heating lowers resin viscosity to speed defoaming and ensures light transmittance and consistency for LED encapsulation. | Laboratory & New‑Material R&D FieldBubbles in R&D samples cause unrepeatable test data and big deviations between duplicate tests for identical formulas. Non‑contact vacuum treatment avoids impurity introduction to guarantee sample purity and reliable data. The compact 27L chamber quickly processes small‑volume samples without waiting for large‑equipment preheating. | Cosmetics & Makeup IndustryBubbles in cosmetic pastes impair texture uniformity and visual quality and bring inaccurate net content after filling. Negative‑pressure defoaming inside sealed chamber keeps original formula composition and works well for cosmetic pastes and lotions. |
✨ Dilemmas of conventional solutions: R&D samples rely on static waiting for bubbles to rise naturally, which takes half an hour or even several hours and greatly slows down experimental progress. Ordinary vacuum chambers have no heating function and cannot handle high‑viscosity materials such as epoxy resin. Without dedicated small‑sample equipment, production‑line units waste excessive energy.
Why Choose SIE‑ZK300
Solve efficiency‑observation pain points for laboratory R&D defoaming
Fast Defoaming With Small‑Sized Chamber27L small chamber equipped with built‑in vacuum pump reaches ‑100kPa within 3‑5 minutes. Compared with large‑chamber equipment, it delivers faster vacuuming and lower energy consumption for R&D prototype tests without long waiting time. All‑in‑one unit with vacuum pump installed at cabinet bottom for instant startup without external accessories. | Multi‑segment Temperature Control for Diverse MaterialsWide adjustable temperature range from ambient to 300℃. Precise control via PID+SSR solid‑state relay, temperature accuracy ±0.5℃ and display accuracy 0.1℃. Supports variable temperature parameters for materials ranging from low‑temperature silicone to high‑temperature epoxy resin. One unit satisfies defoaming demands of multiple materials. | Real‑Time Monitoring Through Viewing WindowHigh‑temperature‑resistant viewing window mounted on door allows observation of internal defoaming status without opening door. Defoaming progress can be judged visually instead of empirical guesswork. Stop operation once bubble escape ceases to avoid over‑processing and save time & energy. |
✨ ZK300 serves as an ideal choice if you have limited lab bench space, need to process high‑viscosity resin or epoxy, or expect real‑time observation of defoaming procedures.
Working Principle
Bubbles expand and burst under negative pressure for gas escape to improve material compactness.
Step 1: Vacuum pumping to build negative pressure: The built-in vacuum pump reaches -100kPa within 3-5 minutes. The negative pressure environment expands bubbles inside materials. Step 2: Heating-assisted defoaming: Thermal radiation heating adjustable from room temperature to 300°C reduces material viscosity and accelerates bubble rupture and escape. Step 3: Non-contact purity preservation: Materials stay static inside the vacuum chamber with no contact from stirring paddles, keeping the chemical properties of materials unchanged. Simple three steps: Vacuum Pumping → Heating Assistance → Non-contact Purity Preservation to improve material compactness. | ![]() |

What is the function of a defoaming machine?
A defoaming machine is a device used to remove bubbles from liquids. Its function is to assist in the liquid mixing, reaction, coating, printing, infusion and other process steps in the production process, avoiding the generation of bubbles and their impact on the final product. In many industrial and laboratory environments, removing bubbles is essential as they may have a negative impact on product quality, such as affecting surface tension and stability. Defoaming machines typically use various techniques such as vibration, ultrasound, centrifugation, etc. to achieve effective bubble removal. It has a wide range of applications, including but not limited to semiconductors, solar energy, optics, biotechnology, materials science, etc.
