How To Choose Right Adhesive Chemical Mixing Tanks

When selecting chemical mixing tanks for adhesive production and storage, it’s essential to consider the characteristics of adhesives, process requirements, and tank design to ensure production efficiency, product quality, and equipment longevity. Below are the key factors to consider:

1. Characteristics of Adhesives

• Viscosity: Adhesives typically have high viscosity, requiring tanks designed for high-viscosity materials. Efficient agitators may be necessary to prevent settling or solidification.

• Corrosiveness:Some adhesives contain acids, bases, or other chemicals that may be corrosive. Tank materials should be resistant to corrosion, such as 304/316L stainless steel or special linings like PTFE or enamel.

• Reactivity: If adhesive production involves chemical reactions (e.g., polymerization or cross-linking), the tank must accommodate the required reaction conditions, such as temperature and pressure.

2. Process Requirements

• Temperature Control: Adhesive production may require heating, cooling, or insulation to maintain optimal operating temperatures. Tanks with jackets, cils, or electric heating systems can fulfill this requirement.

• Mixing Needs:High-viscosity adhesives often need powerful mixing to ensure uniformity. Tanks should be equipped with suitable agitators, such as anchor, frame, or helical ribbon mixers.

• Sealing: Some adhesives are sensitive to moisture or oxygen, requiring tanks with excellent sealing to prevent contamination or degradation.

• Vacuum or Pressure Requirements: If the process involves vacuum or pressurized conditions, tanks must be designed to withstand such demands and comply with relevant pressure vessel standards.

3. Material Selection

• Stainless Steel:

  304 Stainless Steel: Suitable for general adhesives and mildly corrosive environments.

  316L Stainless Steel: Recommended for highly corrosive materials or stricter hygienic requirements.

• Lined Materials:

  For highly corrosive substances, tanks with PTFE, enamel, or other protective linings are ideal.

4. Tank Design

• Capacity and Shape: Choose an appropriate capacity based on production scale. Cylindrical tanks are preferred for high-viscosity adhesives as they facilitate mixing and discharge.

• Discharge System: Conical bottoms with enlarged outlet diameters help ensure smooth discharge of viscous materials.

• Instrumentation: Tanks should include sight glasses, level gauges, and thermometers for real-time monitoring of material conditions.

5. Other Considerations

• Cleaning and Maintenance:Tanks should be easy to clean. For complex adhesive formulations, CIP (Clean-In-Place) systems may be necessary to prevent residue buildup or curing.

• Safety Features:For volatile solvent-based adhesives, tanks should have explosion-proof designs, such as explosion-proof motors and anti-static grounding.

• Regulations and Standards:Tanks should comply with local chemical equipment standards and safety regulations, such as ASME or GB standards.
