Materials for Large Movable Toilets

The materials for large movable toilets vary according to functional requirements and structural characteristics, mainly including the following types:

1. Main Structure Materials The main frame typically uses galvanized steel pipes or light steel structures. Galvanized steel pipes form an anti-rust layer through hot-dip galvanizing, effectively resisting corrosion in humid environments while possessing high load-bearing capacity, allowing them to withstand multiple liftings and relocations without deformation. Light steel structures, primarily composed of high-strength steel, enable rapid assembly through modular design, balancing structural stability with transportation convenience.

2. Wall and Partition Materials The mainstream choice is sandwich panels (color-coated steel sandwich panels or composite panels), which consist of two layers of color-coated steel or aluminum sheets enclosing an insulation layer. Insulation materials include polystyrene (lightweight but with average fire resistance), rock wool (high fire rating), or polyurethane foam (excellent thermal insulation). These materials are lightweight, easy to install, and effectively isolate external temperatures, suitable for various climates.

3. Special Structure Materials

   • Fiberglass Reinforced Plastic (FRP) Materials: Some movable toilet bodies are made of a composite of epoxy resin and glass fibers, featuring a smooth surface and robust structure with acid and alkali resistance and corrosion resistance. The base is molded using colored reinforced FRP molds, further enhancing anti-leakage capabilities, and the double-sided smooth design of the wall panels facilitates cleaning and maintenance.
   • High-Density PVC Panels or Stainless Steel Panels: Commonly used for interior wall decoration, these materials have a dense and smooth surface, resistant to stain absorption and chemical corrosion, suitable for high-frequency use scenarios.

4. Floor and Anti-Leakage Materials The floor often uses non-slip patterned aluminum plates or rubber flooring. The former enhances friction through surface texture while being resistant to acid and alkali corrosion; the latter uses elastic material to cushion impacts, improving user comfort. Some high-end versions add an FRP anti-corrosion layer to the chassis, using seamless design to prevent sewage leakage and avoid odor escape.

5. Water Tank and Pipe Materials Water tanks and sewage pipes commonly use PE (polyethylene) material, whose molecular chain structure provides excellent toughness, allowing it to withstand certain deformations without breaking. It remains flexible in low temperatures, effectively preventing winter freeze-cracking and extending equipment lifespan.

6. Auxiliary Component Materials Hardware such as door panels, locks, and handrails are mostly made of engineering plastics (e.g., ABS, nylon) or stainless steel. Engineering plastics are lightweight, cost-effective, and weather-resistant; stainless steel forms a dense oxide film through surface passivation, remaining rust-resistant and deformation-free even after long-term exposure to humid environments, ensuring functional stability.

7. Smart Function Materials Some eco-toilets use photocatalytic coatings on their interior walls, utilizing nanoscale titanium dioxide as a catalyst to decompose odor molecules (such as ammonia and hydrogen sulfide) under light conditions, achieving air self-purification and reducing manual maintenance frequency.
