Soy Extract PCBTF Cleaning Agent for TPO Roofing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning agents for surfaces like TPO roofing membranes often cause adverse effects, such as damage and environmental hazards due to high VOC content and flammability, which limits their effectiveness and safety.
Innovation Solution
A composition comprising soy extract, acetone, parachlorobenzotrifluoride (PCBTF), and xylene, formulated to have low VOC content and a higher flash point, is used to clean TPO roofing membranes, improving cleanability, weldability, and maximum load while reducing environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional VOC-based cleaning agents are used, then cleaning performance is improved, but flammability and environmental harm increase
Solution Approach 1:
The patent changes the chemical composition parameters by replacing traditional VOC-based solvents with a specific formulation containing soy extract, acetone, PCBTF, and xylene in controlled amounts. This parameter change maintains cleaning effectiveness while reducing VOC content and improving flash point, thereby resolving the contradiction between cleaning performance and safety/environmental concerns
Solution Approach 2:
The invention uses a composite cleaning agent formulation combining multiple components (soy extract, acetone, PCBTF, and xylene) in specific proportions. This composite approach leverages the synergistic effects of different solvents to achieve effective cleaning while controlling overall VOC content and flammability, resolving the contradiction between cleaning power and safety
2Reliability
If physical scrubbing is used to remove foreign contaminates, then mechanical removal is achieved, but surface damage increases
Solution Approach 1:
The patent replaces the mechanical scrubbing system with a chemical cleaning system. The cleaning agent formulation chemically interacts with foreign contaminates (gum, paint, tar) to break down and remove them without requiring aggressive mechanical friction, thereby achieving effective contaminant removal while preventing surface damage
3Reliability
If solvents are used to chemically break bonds, then contaminant removal is improved, but surface damage increases
Solution Approach 1:
The cleaning agent formulation is designed to selectively interact with foreign contaminates rather than the underlying surface material. The specific solvent composition targets gum, paint, and tar while being formulated to minimize adverse effects on the exposed surface, achieving localized chemical action that removes contaminants without damaging the substrate
