Why Phenolic Resin Defoaming Machine Is Required

Phenolic Molding Compound / Bakelite Industry

Bakelite powder and molding compounds are mixtures of resin liquid, fillers and curing agents. Trapped air during mixing creates pores and porosity inside molded plastic parts after injection molding, resulting in fluctuations in dimensional accuracy and insulation performance.

Abrasive & Grinding Tool Industry

Phenolic resin acts as binder for abrasives in grinding wheels and brake pads. Bubbles in mixed materials cause weak local bonding, leading to grain shedding and insufficient strength during grinding, which directly affects service life and safety of abrasive tools.

Refractory Castable Industry

Refractory castables use phenolic resin to bond refractory aggregates. Trapped air reduces the density of cast bodies, impairing high-temperature strength and erosion resistance. Homogeneous mixing and low air content are required.

✨ Traditional Dilemma: More stirring of powders brings more trapped air, resulting in abundant pores and porosity after compaction or casting. Conventional static vacuum pumping cannot handle high-powder systems. Vacuum mixing is therefore required to homogenize powder and resin while degassing simultaneously.

Why Choose SIENOX Phenolic Mixing & Defoaming Solution

Homogenization and Degassing of Powder & Resin

Revolution plus rotation breaks up powder agglomerates. Trapped air is extracted synchronously under vacuum for more homogeneous mixtures and lower gas content.

Denser Green Bodies

Reduces pores and porosity, improves density and strength consistency after sintering or curing, and cuts grain shedding and reject rate of abrasive tools.

Scalable Without Ratio Change

Smooth process scaling from lab-scale C/ZK series to mass-production MIX1000plus. Non-contact operation preserves the ratio of resin and fillers with no cross-contamination.

✨ The MIX60 integrates three core capabilities: deep vacuum defoaming, precision small sample processing, and reproducible process parameters. It serves as an ideal device for laboratory R&D scenarios requiring vacuum-assisted defoaming.

  • How does the stirring and defoaming machine work?

    The SIENOX stirring and defoaming machine performs defoaming through centrifugal force at revolution and stirring through shear force formed by revolution and rotation,

    Assisted by a vacuum pump to extract gas and achieve a vacuum state, removing nanoscale tiny bubbles. No contact with materials, no secondary pollution, and no secondary waste.

  • 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.

Precautions for Use

PrecautionsOperating Instructions
Proportioning & FeedingFeed resin liquid, powder and curing agent according to process ratio before vacuum mixing and degassing.
Loading & Rotation SpeedPowder-containing systems tend to settle. Match cup loading volume with rotation speed to ensure homogeneous mixing.
Timely FormingPerform compaction or casting immediately after mixing to prevent moisture reabsorption or surface drying which impairs forming.
Dust Prevention & CleaningClean cups and chamber promptly after powder mixing to avoid residual material curing and affecting subsequent batches.

* Internal laboratory test data. Actual results depend on material formulation and process. Contact sales for real customer cases.
