Fluid Resistance Control in Mixing Tubes: Impact on Dispensing Accuracy and Flow Stability

2025-11-03

Fluid Resistance Control in Mixing Tubes: Impact on Dispensing Accuracy and Flow Stability

 

The fluid resistance characteristics of plastic mixing tubes directly correlate with the pressure output and flow control precision of dispensing systems:

 

Hazards of Excessive Resistance: If the mixing tube's inner diameter is too small or the blade design is suboptimal, fluid resistance surges dramatically. This forces the dispensing pump to operate beyond capacity, causing pressure fluctuations that result in inconsistent output volumes. Additionally, it prolongs the residence time of adhesive within the tube. For fast-curing adhesives, this can lead to premature curing and blockages, interrupting production processes.

 

Importance of Resistance Matching: Mixed tubes must be matched to the viscosity of the adhesive. For instance, high-viscosity thermal pastes require large-diameter, low-resistance tubes to prevent intermittent dispensing due to excessive resistance. Conversely, low-viscosity anaerobic adhesives demand appropriately controlled resistance to ensure sufficient mixing time within the tube while avoiding excessive flow rates that could disrupt the mixing ratio.
