Liquid Particle Coating Composition for Ambient-Temperature Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coatings for granular materials, particularly fertilizers, made from renewable oils, are solid at ambient temperature, making direct application impossible and posing safety risks due to the need for heating, while current liquid formulations either fail to prevent agglomeration or pose safety hazards.
Innovation Solution
A liquid coating formulation comprising anionic surfactants with specific functional groups and renewable oils, allowing application at ambient temperature and effectively preventing agglomeration and dust formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If renewable oils are used as coating material, then environmental compatibility is improved, but the coating becomes solid at ambient temperature making application difficult
Solution Approach 1:
The patent changes the physical state parameter of the coating formulation from solid to liquid by adjusting the oil composition and adding specific additives, enabling application at ambient temperature while maintaining renewable oil benefits
Solution Approach 2:
The patent creates a composite coating formulation combining renewable oils with specific additives (such as polyols and surfactants) to achieve both liquid state at ambient temperature and effective coating performance
2Object-affected harmful factors
If renewable oils are used as coating material, then environmental compatibility is improved, but heating is required which creates safety risks
Solution Approach 1:
The patent changes the melting point parameter of the coating formulation by selecting specific renewable oils with lower melting points and adding liquid additives, eliminating the need for heating and associated safety risks
3Ease of operation
If liquid coating formulations are used, then application ease is improved, but they fail to prevent agglomeration effectively
Solution Approach 1:
The patent develops a composite liquid formulation combining renewable oils with specific additives that work synergistically to provide both liquid state for easy application and effective agglomeration prevention through enhanced surface coverage and adhesion
Solution Approach 2:
The patent introduces intermediary substances (additives such as polyols and surfactants) that mediate between the renewable oil and the granular material surface, improving wetting and adhesion to prevent agglomeration effectively
