Liquid TAED Bleach Activation for Pumpable Peroxy Laundry Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing powdered form of tetraacetylethylenediamine (TAED), a common bleach activator, cannot be pumped through liquid dispensing systems used in industrial and institutional laundry operations, limiting its effectiveness and usability in enhancing peroxy bleaches.
Innovation Solution
Converting TAED into a liquid form by dissolving it in an alkaline aqueous solution, allowing it to be used as a liquid peroxy bleach activator that can be pumped through dispensing systems, combined with a peroxy compound to form an activated bleaching system for improved bleaching and antimicrobial effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If TAED is used in powdered or granular form, then it can enhance the bleaching effectiveness of peroxy compounds, but it cannot be pumped through liquid dispensing systems used in industrial and institutional laundry operations
Solution Approach 1:
The patent changes the physical state parameter of TAED from solid (powdered or granular) to liquid form by dissolving it in an alkaline aqueous solution. This parameter change enables TAED to be pumped through liquid dispensing systems while maintaining its bleaching effectiveness when combined with peroxy compounds.
Solution Approach 2:
The patent introduces an alkaline aqueous solution as an intermediary medium to dissolve TAED, enabling it to transition from an unpumpable solid state to a pumpable liquid state. This intermediary solution acts as a carrier that preserves TAED's functionality while enabling its delivery through existing liquid dispensing infrastructure.
2Reliability
If traditional powdered TAED is used, then bleaching effectiveness is improved, but the system requires high temperatures and pH levels which increases energy consumption and environmental harm
Solution Approach 1:
The patent changes the chemical form of TAED from powdered to dissolved liquid state, which fundamentally alters its reactivity characteristics. This parameter change enables the bleaching system to achieve effective performance at lower temperatures and pH levels, thereby reducing energy consumption and environmental impact.
3Ease of manufacture
If powdered TAED is used, then it can be stored and handled, but it cannot be automatically dispensed through liquid systems, requiring manual intervention
Solution Approach 1:
The patent transforms TAED from solid powder to liquid solution form, changing its physical parameters to match the requirements of automated liquid dispensing systems. This parameter change enables full automation of the dispensing process while maintaining ease of storage and handling characteristics.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the effective use of TAED in liquid form, enhancing the bleaching and antimicrobial properties of peroxy compounds, reducing the need for high temperatures and pH levels, thus saving energy, reducing environmental harm, and improving worker safety while maintaining effectiveness comparable to traditional methods.
Implementation Method 1
The TAED may be fluidized and may be solubilized in water by adding an alkaline material to a water-TAED mixture
Implementation Method 2
Peroxy compounds such as hydrogen peroxide, sodium perborate, sodium percarbonate, sodium persulfate, sodium perphosphate, peroxyacetic acid and numerous organic peroxides are well known for their ability to release peroxide in solution
Implementation Method 3
Adding a bleach activator to peroxy compounds will enhance the effectiveness of the peroxide species to improve the bleaching and antimicrobial properties of the peroxy compound
