Solution Overview
Problem
Existing filtration technologies face challenges in efficiently separating components from fluids at elevated temperatures and in harsh chemical environments, particularly in maintaining interconnectivity of particles or fibers to ensure effective separation without complete coating, which affects the durability and performance of filtration membranes.
Innovation Solution
A composite solid article is created using a high molecular weight fluoropolymer or polyamide binder that connects interactive particles or fibers at discrete points, forming a porous structure allowing direct fluid interaction and separation, with a binder ratio of 0.2 to 150 parts to 10 to 500 parts of particles, enabling effective separation of dissolved or suspended materials across various industrial applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a complete coating binder is used to connect particles, then mechanical integrity is improved, but porosity and fluid interaction are reduced
Solution Approach 1:
The binder is applied in a segmented manner rather than as a complete coating. The binder connects particles at discrete points, creating isolated bonding zones that maintain structural integrity while preserving porosity in the spaces between bonding points.
Solution Approach 2:
The binder provides localized connection at specific discrete points on particle surfaces rather than uniform coverage. This local quality approach ensures mechanical strength at bonding points while maintaining fluid accessibility and porosity in the overall structure.
2Quantity of substance
If particles are bound at discrete points, then porosity and fluid interaction are improved, but mechanical integrity is reduced
Solution Approach 1:
The binder is pre-applied to particles or surfaces before final assembly, creating discrete bonding points that are optimally positioned to provide mechanical support while preserving porosity. This preliminary action ensures proper connectivity is established during formation.
Solution Approach 2:
The binder application parameters are controlled to achieve discrete point bonding rather than complete coating. By adjusting binder concentration, application method, and drying conditions, the system transitions from continuous coating to discrete point connection, optimizing both strength and porosity.
3Ease of manufacture
If conventional binders are used, then ease of manufacture is improved, but chemical resistance and durability in harsh environments are reduced
Solution Approach 1:
The invention uses composite material systems where the binder is specifically selected for its chemical resistance properties (such as fluoropolymers or polyamides) while maintaining compatibility with the interactive particles. This composite approach ensures both manufacturability and durability in harsh chemical and high-temperature environments.

AI summary
The invention relates to a porous separation article having a fluoropolymer, polyamide, PEEK, or PEKK binder interconnecting one or more types of interactive powdery materials or fibers. The interconnectivity is such that the binder connects the powdery materials or fibers in discrete spots rather than as a complete coating, allowing the materials or fibers to be in direct contact with, and interact with a fluid. The resulting article is a formed multicomponent, interconnected web, with porosity. The separation article is useful in water purification, as well as in the separation of dissolved or suspended materials in both aqueous and non-aqueous systems in industrial uses. The separation article can function at ambient temperature, as well as at elevated temperatures.
