Production of Mobile Toilets Using Sandwich Panels

Mobile toilets made from sandwich panels are temporary sanitation facilities assembled modularly using color-steel sandwich panels as the primary building material. Their core principles, structural features, and applicable scenarios are as follows:

I. Core Materials and Structure
Color-steel sandwich panels consist of two thin steel sheets laminated with an insulating core material in the middle, with the type of core directly affecting performance:

1. Expanded Polystyrene (EPS): Low cost and good thermal insulation, but with a lower fire rating, suitable for low-risk temporary locations.
2. Rock Wool: Excellent fire resistance (Class A non-combustible) and outstanding sound insulation, commonly used in scenic areas or high-security scenarios.
3. Polyurethane (PU): Balanced overall performance, combining thermal insulation with structural strength, suitable for extreme climates.
   Walls and roofs use these panels, supported by a steel frame base to form an enclosed space. Inside, they are equipped with squat toilets, sit toilets, sinks, and other facilities. Some products integrate sewage collection tanks or drainage interfaces to adapt to environments without sewer systems.

II. Technical Advantages

1. Efficient Installation: Modules such as walls and roofs are prefabricated in the factory, requiring only assembly and connection on-site, shortening the construction period to 1-3 days, significantly faster than traditional brick-and-mortar structures.
2. Flexible Adaptation: Can be customized to single units, multi-row arrangements, or two-story structures based on site dimensions, supporting barrier-free designs (such as ramps and handrails) to meet diverse needs in construction sites, scenic areas, and event venues.
3. Easy Relocation: Entirely connected with bolts, allowing for disassembly and transfer by crane, with a reuse rate exceeding 80%, reducing construction waste.
4. Environmental Tolerance: The color-steel sheets are corrosion-resistant on the surface, combined with the insulating core, enabling stable operation in environments ranging from -30°C to 50°C, with a lifespan of 10-30 years.

III. Typical Application Scenarios

1. Construction Sites: The site toilets produced by Yangzhou Lvjie use rock wool cores with a Class A fire rating and odor control designs, capable of serving 200 people simultaneously.
2. Large Events: The color-steel toilets provided by Wuhan Lanyue support rapid deployment, with the ability to install 50 units in a single day, equipped with intelligent exhaust systems to effectively control odors.
3. Eco-Scenic Areas: Some products integrate solar power and biodegradation technologies to achieve zero sewage discharge, aligning with environmental protection requirements.

IV. Industry Cases
Yangzhou Lvjie's intelligent eco-toilets feature modular designs that expand the sewage tank capacity to 2m³, supporting 72 hours of unattended operation. Wuhan Lanyue's customized services can deliver uniquely shaped toilets within 48 hours, fitting narrow municipal road spaces. These products have passed ISO9001 quality certification and comply with the national standard Technical Requirements for Mobile Toilets (GB/T 38837-2020).
