1. Application Scenario
main structure
Walls and roofs: Made of hollow plastic sheets (such as HDPE or PP honeycomb boards), they combine strength and thermal insulation, making them suitable for rapid construction.
Flooring: Non-slip plastic composite boards (such as PVC stone plastic flooring) are waterproof and moisture-resistant, avoiding the decay issues of traditional materials.
Sanitary facilities
Partition board: Made of high-density polyethylene (HDPE) or ABS board, with a smooth and easy-to-clean surface, resistant to chemical corrosion, suitable for toilet cubicles.
Toilet and washbasin: An integrated structure made of modified polypropylene (PP) or polycarbonate (PC) plates, which is impact-resistant and antibacterial.
Auxiliary components
Storage cabinets and handrails: UHMWPE plates (such as Mitsui Chemicals L8002) exhibit high wear resistance, making them suitable for components subjected to frequent use.
Drainage channels and ventilation ducts: UPVC (Unplasticized Polyvinyl Chloride) boards are resistant to acids and alkalis, ensuring long-term stable operation.
III. Core Advantages of Plastic Sheeting
Lightweight and portability
Plastic sheets have a low density (for example, PP has a density of about 0.9g/cm³), which reduces the overall weight of mobile toilets, making them easier to transport and install.
Environmental resistance
UV resistance: HDPE boards with the addition of carbon black or stabilizers can be used outdoors for a long time.
Resistance to chemical corrosion: Prevent the erosion of materials by urine, detergents, etc.
Modular Design
Plastic sheets are easy to cut and weld, enabling rapid customization and adapting to various sizes and functional requirements (such as accessible toilets and mother-and-baby rooms).
Low maintenance cost
The smooth surface is resistant to bacterial growth, requiring only water rinsing for cleaning, thereby reducing maintenance frequency.
IV. Environmental Protection Trends and Innovation Directions
Substitution of bio-based materials
Polylactic acid (PLA) plates developed by Japanese companies such as Showa Denko are biodegradable and reduce dependence on petroleum, and are gradually being applied to disposable parts.
Circular economy practice
Using recyclable plastics (such as recycled HDPE) to manufacture boards meets the requirements of the Plastic Resource Recycling Law.
Modular design facilitates disassembly and recycling, reducing resource waste.
Low-carbon manufacturing process
The energy-saving extrusion technology developed by Japan Steel Works, such as precision screw design, reduces production energy consumption and lowers carbon emissions.
V. Case Reference
Japanese mobile toilet standard: Utilizing a combination of FRP and PP honeycomb panels, it meets the requirements of JIS (Japanese Industrial Standards) for weather resistance and fire resistance.
Post-disaster emergency toilets in Thailand: Utilizing recycled HDPE boards, and aligning with the local plastic ban policy, to facilitate rapid deployment and environmentally friendly recycling.
Plastic sheets, with their comprehensive performance, have become the mainstream choice in the field of mobile toilets. In the future, with the development of bio-based materials and recycling technologies, their environmental protection properties will be further enhanced, driving the industry towards sustainable transformation.
