Resin Emulsion Covering Layer for Open-Air Pile Dust Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydrophobic treatment agents for open-air piles result in weak and fragile coating films that crack, allowing moisture penetration and dust generation, which is economically and environmentally detrimental.
Innovation Solution
A coating agent comprising acrylic-based resin and polyvinyl alcohol (PVA)-based resin is applied to open-air piles, forming a strong and durable film that prevents moisture increase and dust generation by enhancing film strength through fusion of the resins.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If organic waste is piled open-air for composting, then composting process proceeds, but dust is generated and moisture increases
Solution Approach 1:
A covering layer is applied over the organic waste pile to physically block dust particles from being generated and dispersed into the air during the composting process, while still allowing moisture to pass through via capillary action
2Productivity
If organic waste is piled open-air for composting, then composting process proceeds, but moisture increases
Solution Approach 1:
The covering layer acts as a selective barrier that allows moisture to pass through via capillary action while blocking dust, thereby controlling moisture levels in the composting waste
Solution Approach 2:
The covering layer is designed with porous properties that enable capillary action, allowing moisture to be absorbed and transported through the layer while maintaining structural integrity and blocking dust particles
3Object-generated harmful factors
If covering layer is applied to prevent dust, then dust generation is reduced, but device complexity increases
Solution Approach 1:
A simple covering layer is applied over the waste pile that provides effective dust suppression through its physical barrier properties while maintaining ease of application and removal
Solution Approach 2:
The covering layer is designed to be self-regulating, allowing moisture to pass through via capillary action without requiring external control mechanisms, thereby simplifying the overall system operation
