Haixi Process Mobile Toilet

The Haixi process mobile toilet is a mobile sanitation facility that uses high-strength steel and color-coated steel sheets as its core materials, integrating modular design and environmental protection technologies to achieve rapid assembly, resource recycling, and strong environmental adaptability. Its technical features and environmental advantages can be analyzed from the following aspects:

1. Manufacturing Process: Lightweight and Modular Design

The structural frame of the Haixi process mobile toilet adopts high-strength cold-formed thin-walled steel, achieving lightweight through cold-forming technology while maintaining sufficient structural support for frequent movement and installation needs. The connection nodes of the frame generally use bolt assembly instead of welding, facilitating disassembly and reassembly while ensuring structural integrity. The surface-covered color-coated steel sheets are composite materials formed by continuous roll coating and baking processes on metal substrates, mostly galvanized steel sheets or aluminum-zinc alloy steel sheets. The coating consists of a primer, topcoat, and protective film, providing corrosion resistance, weather resistance, and thermal insulation. In response to the strong ultraviolet radiation and large temperature differences in plateau regions, Qinghai Shiquan Color Steel Factory has made targeted adjustments to the coating formula and thickness, such as increasing ultraviolet absorbers or adjusting pigment ratios, to extend the material's service life.

Throughout the production process, modular design is consistently applied. Wall and roof panels are precisely cut and pre-punched in the factory, using hidden locking edge technology to replace some adhesives and reduce volatile organic compound emissions. The panel assembly process incorporates airtightness testing procedures, simulating wind pressure environments to inspect the sealing performance of joints, ensuring the structural stability of the finished product in windy plateau environments. The installation of internal partitions and functional units follows prefabrication principles, with all pipeline channels reserved during the panel forming stage to avoid dust and waste generation from on-site cutting.

2. Environmental Characteristics: Resource Recycling and Pollution Control

The environmental friendliness of the Haixi process mobile toilet is reflected in its full lifecycle management.

1. Resource Utilization: Standardized and modular design significantly reduces construction waste generated during on-site construction, such as concrete residues and brick fragments. Precise material calculation and nesting reduce raw material waste rates, for example, by optimizing layout during color-coated steel sheet cutting to minimize offcuts.
2. Water Treatment System: It integrates a multi-stage combination technology of physical sedimentation, biological degradation, and chemical treatment. For example, it uses a combination of anaerobic and aerobic biological reactions, utilizing specific microbial communities to decompose organic matter. The treated effluent can be used for flushing or green irrigation, reducing pressure on municipal sewer networks and freshwater resource consumption.
3. Excreta Disposal: Some products use replaceable sewage storage tanks, combined with professional collection and centralized treatment, to collect dispersed pollution sources for resource utilization, such as producing organic fertilizers or biogas fermentation, avoiding non-point source pollution caused by random discharge.
4. Recyclability: The main structural steel and color-coated steel sheets are highly recyclable materials. After the product reaches its service life, most materials can enter the recycling loop, reducing the amount of construction waste sent to landfills.
5. Energy Consumption Control: Factory-based production centralizes energy-consuming processes within the factory, facilitating the implementation of energy-saving measures such as waste heat recovery and optimized cutting layout. For example, Qinghai Shiquan Color Steel Factory converts waste heat generated during welding and curing processes into auxiliary energy for the heating system, reducing overall production energy consumption.
6. Other Environmental Measures: Offcuts are classified and recycled during production, with metal waste compressed and sent to recycling plants, and non-metal waste utilized according to material properties. Water resources for cleaning equipment are circulated in a closed loop, undergoing sedimentation, filtration, and neutralization treatment before being reused in the production line. The coating process uses water-based epoxy coatings with water as the dispersion medium, containing lower levels of organic solvents than traditional oil-based coatings, reducing harmful gas generation at the source.

3. Enterprise Products: Differentiated Design and Scenario Adaptation

Different enterprises have launched differentiated products tailored to the needs of the Haixi region.

• Guting Metal Products: Their products adopt a double-layer galvanized steel sheet + polyurethane sandwich panel structure, with measured door frame deformation rates below 0.12% under working conditions of -30°C to 35°C, possessing plateau wind pressure resistance and dust prevention capabilities. They support customized exterior color matching and barrier-free ramp interfaces, but the standard model does not come with a standard solar power supply system, requiring additional configuration. Suitable for municipal short-term projects, scenic area peak season supplements, and other scenarios sensitive to delivery timelines.
• Jinmuhe Metal Products Co., Ltd.: They mainly offer integrated prefabricated toilet units, using Q235B hot-dip galvanized steel frames + FRP composite panel enclosures, with measured salt spray test results of 1000 hours without substrate corrosion, showing good corrosion resistance for areas near salt lakes. They come standard with LED energy-saving lighting, foot-operated water-saving valves, and simple ventilation and airflow guiding structures, but the internal space layout is compact, with a net usable height of 2.15m for the 6㎡ model, slightly cramped for users over 1.85m tall. Suitable for long-term stationing in mining areas, ecological monitoring station support, and other medium- to long-term deployment scenarios with high material durability requirements.
