Working Requirements

• Material Type: AB structural adhesives (two‑component adhesives including black AB structural adhesive, white AB structural adhesive, epoxy structural adhesive, polyurethane structural adhesive, etc.)

• Initial State: AB structural adhesive is a two‑component system. Component A (resin) and Component B (hardener) require sufficient and homogeneous blending. A large number of stubborn micro‑bubbles are generated during mixing. Featuring high viscosity and poor fluidity, bubbles cannot escape naturally, which directly impairs structural bonding strength and durability.

• Processing Target: Fully and homogeneously mix A/B components of AB structural adhesive, thoroughly remove stubborn micro‑bubbles, ensure uniform and fine adhesive texture, achieve qualified structural bonding strength, and meet high‑strength bonding process requirements for building curtain walls, automotive bodies, aerospace and other scenarios.

Comparison Before and After Optimization

Before Optimization — Pain Points of Traditional Processes

AB structural adhesives are widely adopted in building curtain walls, automotive bodies, aerospace and other fields, where bonding strength directly determines structural safety. Nevertheless, massive bubbles are generated during mixing of two‑component systems, and conventional processing methods face multiple challenges:

• Inhomogeneous blending of A/B components: Black and white AB adhesives have high viscosity. Traditional stirring fails to fully homogenize A/B components, resulting in incomplete curing and reduced bonding strength.

• Difficult‑to‑remove stubborn micro‑bubbles: Micro‑bubbles produced in mixing cannot escape naturally due to high viscosity, forming voids after curing and severely weakening structural bonding strength and durability.

• Uneven color mixing: Insufficient mixing of black or white AB adhesives leads to color inconsistency and poor appearance quality (e.g. color deviation on white structural adhesives).

• Unstable structural bonding strength: Bubbles and uneven mixing reduce effective bonding area and cause drastic fluctuation of bonding strength, bringing potential structural‑safety hazards.

• Low efficiency of traditional stirring: Mechanical paddle stirring delivers low efficiency and requires repeated operations, greatly disrupting production tact time.

Solutions

• Vacuum defoaming + planetary motion: Under vacuum conditions, powerful shear force and convection are generated by planetary revolution‑and‑rotation motion. Stubborn micro‑bubbles inside AB structural adhesive gradually rise and are extracted, while A/B components achieve thorough homogeneous blending.

• Homogeneous two‑component mixing: Planetary motion realizes 360° dead‑zone‑free mixing. Component A (resin) and Component B (hardener) are fully blended under gentle and uniform force field for complete curing and qualified bonding strength.

• Excellent color consistency: Treated black and white AB adhesives feature uniform color without chromatic aberration for superior appearance performance.

• Improved structural bonding strength: Fully‑defoamed AB structural adhesive provides sufficient bonding area with high and stable bonding strength, satisfying high‑strength structural‑bonding demands for building curtain walls, automotive bodies and more.

Advantages of Mixing‑Defoaming Machine

• Efficient removal of stubborn micro‑bubbles: Vacuum environment combined with planetary motion effectively eliminates stubborn micro‑bubbles in AB structural adhesive and avoids void risks after curing.

• Homogeneous two‑component mixing: Gentle and uniform planetary revolution‑rotation motion ensures full blending of A/B components, complete curing and qualified bonding strength.

• Excellent color consistency: Uniform color of black / white AB adhesives after processing, free of chromatic aberration and with outstanding appearance quality.

• Precisely adjustable parameters: Rotation speed, duration and vacuum level are configurable to optimize process parameters for AB adhesives of different viscosity and formulas.

• Time‑saving & high‑efficiency: The whole mixing‑defoaming process is completed within several minutes for greatly improved productivity.

• Paddle‑free & easy‑to‑clean: Contact‑free design. Only outer container cleaning or container replacement is needed for formula change to prevent cross‑contamination.
