Introduction

Fish boxes are crucial in fish transport, maintaining optimal conditions. The material used for the moulds directly affects the box's performance and durability. This article evaluates materials commonly used to manufacture fish box moulds, providing a detailed analysis of their advantages and drawbacks.

Importance of Material Selection for Fish Box Moulds

Choosing the right material impacts mould longevity, thermal performance, and structural integrity. Fish boxes must withstand rigorous conditions, including moisture exposure and temperature fluctuations. Poor material selection can lead to increased costs and environmental impact due to frequent replacements.

Common Materials Used in Fish Box Moulds

• Polyethylene (PE): Offers excellent resistance to impact and chemicals, with a density range typically between 0.910 and 0.970 g/cm³.
• Polypropylene (PP): Known for its fatigue resistance, with a melting point of approximately 130°C, suitable for high-temperature applications.
• Polystyrene (PS): Provides superior insulation properties, with a thermal conductivity of around 0.033 W/m·K.
• Fiberglass Reinforced Plastic (FRP): Combines high strength and low weight, offering a tensile strength of 1,000 MPa.

Numerical Analysis of Material Performance

A comparative analysis of these materials is essential. Polyethylene's high impact resistance makes it suitable for harsh handling, while polypropylene's higher melting point supports sterilization and cleaning processes. Polystyrene, with its superior thermal insulation, minimizes the cooling load for transported fish. Fiberglass provides long-term durability but involves higher initial costs.

Comparative data:

• Impact Resistance (kJ/m²): PE: 90, PP: 40, PS: 20, FRP: 300
• Thermal Conductivity (W/m·K): PE: 0.4, PP: 0.22, PS: 0.033, FRP: 0.25
• Density (g/cm³): PE: 0.96, PP: 0.92, PS: 1.05, FRP: 1.5
