Biopolymer Release Agent Formulation With Low-Residue Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processing aids, particularly those with a release effect, often form residues, pose health hazards, are environmentally unfriendly, and require complex preparation processes, while liquid aids have low active substance concentration.
Innovation Solution
A formulation comprising a biopolymer, such as lignin or lignin derivatives, and surfactants is used to create a processing aid that is easily convertible into an aqueous form, eliminating the need for inorganic separator components and minimizing residue formation, with a high active substance content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional processing aids with inorganic separator components are used, then release effect is achieved, but residues are formed and health hazards arise
Solution Approach 1:
The patent removes inorganic separator components from the processing aid formulation, extracting only the harmful elements while retaining the essential release functionality through biopolymer and surfactant combinations
Solution Approach 2:
The invention changes the chemical composition parameters from inorganic-based to biopolymer and surfactant-based systems, fundamentally altering the material properties to eliminate residue formation while maintaining release effects
2Ease of operation
If liquid processing aids are used, then ease of application is improved, but active substance concentration decreases
Solution Approach 1:
The patent creates a composite formulation combining biopolymers and surfactants that work synergistically to provide both liquid-state ease of application and high active substance concentration through enhanced solubility and stability
3Object-generated harmful factors
If biopolymer and surfactant formulation is used, then environmental friendliness and active substance concentration are improved, but preparation complexity may increase
Solution Approach 1:
The patent merges biopolymer and surfactant components into a single integrated formulation system that achieves environmental friendliness and high efficacy while simplifying preparation through combined functionality
