Gel-like Coating for Viscous Substance Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container technologies fail to maintain effective slipping properties for viscous substances like mayonnaise and ketchup over time, leading to adhesion issues and incomplete discharge, even with oil film coatings.
Innovation Solution
A gel-like coating is formed on the inner surface of containers using an oily liquid mixed with fine solid particles, which provides improved and stable slipping properties for viscous substances by maintaining a network structure and reducing wear from flowing substances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an oil film is formed on the container surface to improve slipping properties, then the initial slipping property is improved, but the slipping property decreases after long periods of time
Solution Approach 1:
The invention uses a composite coating comprising both an oil component and a fluorinated polymer component. The fluorinated polymer forms a durable base layer that maintains structural integrity over time, while the oil component provides initial low-friction properties. This composite structure combines the advantages of both materials: the polymer provides long-term durability and the oil provides excellent initial slipping properties, resolving the contradiction between initial performance and long-term maintenance.
Solution Approach 2:
The invention changes the chemical composition parameters of the coating by introducing fluorinated polymers with specific fluorine content (5-30 mass%). This parameter modification fundamentally alters the coating's temporal behavior, transforming it from a simple oil film that degrades over time to a stable composite that maintains consistent slipping properties throughout its service life.
2Ease of operation
If lubricant is added to the synthetic resin to improve slipping properties, then the slipping property is improved, but the substance complexity increases
Solution Approach 1:
Instead of adding lubricant additives to the bulk resin material, the invention extracts the lubrication function to a separate surface coating layer. This separation allows the bulk resin to remain simple and structurally sound, while the surface coating independently provides the slipping properties through its oil-fluoropolymer composition.
Solution Approach 2:
The fluorinated polymer acts as an intermediary between the container wall and the viscous substance. It creates a stable interface layer that facilitates slipping, while the oil component enhances this effect. This intermediary approach provides lubrication without requiring complex additive packages in the base resin.
