Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermoplastic resin compositions for cleaning molding processing machines lack enhanced cleaning performance, particularly in effectively removing residual materials from machine interiors.
Innovation Solution
A thermoplastic resin composition comprising an olefin-based resin (A) and a nonionic surfactant (B) with a hydrophile-lipophile balance (HLB) of 13 to 20, along with additional nonionic surfactant (B2) and optional thermoplastic elastomer (C) and inorganic filler (D), optimized for improved detergency and workability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a polyolefin resin is combined with other components as a cleaning agent, then it provides basic cleaning function, but the cleaning performance is insufficient for effectively removing residual materials
Solution Approach 1:
The patent changes the chemical composition parameters by introducing a nonionic surfactant with specific HLB value (13-20) into the polyolefin resin system. This parameter modification enhances the resin's ability to emulsify and remove residual materials, transforming it from a basic cleaning agent to an effective cleaning composition that addresses the insufficient cleaning performance issue.
Solution Approach 2:
The patent creates a composite material system by combining polyolefin resin with nonionic surfactant in specific proportions (0.5-10 parts by mass per 100 parts by mass of polyolefin resin). This composite structure integrates the cleaning capabilities of both components, where the surfactant enhances the resin's cleaning performance while the resin provides structural integrity and cleaning action.
2Reliability
If cleaning agents are used to remove residual materials, then cleaning effectiveness improves, but the complexity of composition increases
Solution Approach 1:
The patent optimizes the composition by specifying precise parameter ranges: nonionic surfactant with HLB value of 13-20 and content of 0.5-10 parts by mass per 100 parts by mass of polyolefin resin. These controlled parameter changes achieve enhanced detergency while maintaining composition simplicity and manufacturability.
