The liquid fluidity characteristics of dishwasher capsules directly affect their cleaning efficiency, uniformity of component release, and compatibility with dishwasher systems. The following is an analysis from the aspects of technical principles, performance, and optimization directions:
First, the influence of liquid fluidity on cleaning efficiency
Rapid diffusion and coverage capabilities
Capsules with strong liquid fluidity can quickly spread to all corners of the dishwasher with the water flow after dissolving, ensuring that the detergent evenly covers the surface of the tableware. If the fluidity is insufficient, the liquid may concentrate in a local area, resulting in incomplete cleaning of some tableware.
Analogy: A liquid with good fluidity is like “flowing milk”, which can quickly seep into the gaps of tableware. Liquids with poor fluidity are similar to “honey”, spreading slowly.
Foam generation and decontamination work in synergy
Surfactants are the key components for generating foam, and their fluidity affects the fineness and stability of the foam. Liquids with moderate fluidity can generate uniform and fine foam, enhancing the decontamination ability. If the fluidity is too strong, the foam may be too sparse to fully wrap the oil stains. If the fluidity is too weak, the foam may be too viscous, hindering the scouring of water flow.
Second, the influence of liquid fluidity on the release of components
The precision of phased release
High-quality capsules achieve phased release by adjusting the fluidity of the liquid:
Initial release: The highly fluid liquid rapidly releases surfactants after dissolution, decomposing oil stains.
Later release: A slightly less fluid liquid slowly releases enzyme preparations and bleach to remove stubborn stains.
Similar to the principle of “coffee layering”, the difference in fluidity causes different components to be released at specific times.
Avoid the precipitation and residue of components
Capsules with poor liquid fluidity may cause active ingredients (such as enzyme preparations) to precipitate at the bottom of the dishwasher, preventing them from fully contacting the tableware. Liquids with overly strong fluidity may cause the components to be lost prematurely, reducing the cleaning effect.
Third, the fluidity of the liquid and its compatibility with the dishwasher system
Compatibility of spray arms
The design of the dishwasher spray arm needs to be matched with the fluidity of the liquid:
High-pressure spray: Liquid with strong fluidity can be quickly dispersed to the surface of tableware through high-pressure water flow.
Low-pressure spray: Liquid with moderate fluidity can prevent local residue caused by insufficient water flow pressure.
Data reference: Research shows that when the liquid viscosity is within the range of 500-2000 mPa·s, it has the best compatibility with the spray arms of most commercial dishwashers.
The balance between temperature and dissolution rate
The water temperature of the dishwasher (60-80℃) affects the fluidity of the liquid:
High-temperature accelerated dissolution: Liquids with strong fluidity dissolve faster at high temperatures, but it is necessary to avoid the loss of components due to reduced viscosity.
Low-temperature stability maintenance: Liquids with moderate fluidity can still maintain uniform diffusion at low temperatures and avoid sedimentation.
Fourth, the optimization direction of liquid fluidity
Adjustment of component proportion
The viscosity of the liquid is controlled by optimizing the proportion of surfactants, thickeners and solvents. For example, adding a small amount of polyethylene glycol can reduce viscosity and improve fluidity. Adding natural colloids (such as xanthan gum) can moderately increase viscosity and prevent the precipitation of components.
Multilayer structure packaging
It adopts a multi-layer capsule design. The outer layer liquid has strong fluidity and can quickly release surfactants. The inner liquid has slightly weaker fluidity and slowly releases enzyme preparations and bleach. This design takes into account both the initial decontamination and the later deep cleaning requirements.
Intelligent adaptation technology
In the future, capsules may automatically adjust the fluidity of the liquid by adding temperature-sensing or water-sensing components. For example, automatically increase fluidity in hard water areas to prevent component sedimentation; Automatically reduce viscosity in high-temperature environments to prevent component loss.
Fifth, the risk of insufficient or excessive liquid fluidity
The risk of insufficient liquidity
Incomplete cleaning: The liquid cannot evenly cover the tableware, resulting in oil stains remaining.
Dishwasher blockage: Viscous liquids may clog the spray arms or pipes, affecting the normal operation of the equipment.
Increased costs: Secondary cleaning or manual intervention is required, which increases operating costs.
The risk of excessive liquidity
Component loss: The liquid is prematurely lost to the drainage system, resulting in a decline in the cleaning effect.
Excessive foam: Liquids with overly strong fluidity may generate excessive foam and overflow the dishwasher.
Environmental protection issues: The loss of components increases the burden of wastewater treatment and does not meet environmental protection requirements.
Conclusion
The liquid fluidity of dishwasher capsules needs to strike a balance among cleaning efficiency, uniformity of ingredient release and compatibility with the dishwasher system. Either too strong or too weak fluidity may lead to poor cleaning results, equipment failure or increased costs. By optimizing the component ratio, adopting multi-layer structure packaging and developing intelligent adaptation technology, precise control of liquid fluidity can be achieved, thereby enhancing the overall performance of the capsule.
