Jiangjin Mobile Toilet Processing

The processing of mobile toilets in Jiangjin is a complex process involving multi-system integration and regional industrial collaboration, with core aspects including functional module design, material selection and processing, system integration, and regional industrial support, as detailed below:

1. Functional Module Design and Processing Requirements
The processing of mobile toilets requires the integration of four core systems:

• Structural Framework System: Utilizes lightweight, high-strength metal materials (such as aluminum alloy or galvanized steel), formed through welding, riveting, or bolting processes. The framework must meet load requirements during lifting, transportation, and use, including wind pressure and earthquake resistance, often necessitating finite element analysis for structural optimization.
• Enclosure and Insulation System: Walls use composite panels (such as metal-faced sandwich panels), offering fire resistance, thermal insulation, and waterproofing; floors require slip resistance and corrosion resistance, commonly using slip-resistant aluminum plates or PVC flooring. Roof design must consider drainage slopes and snow load capacity.
• Sanitation and Sewage System: Technical types are selected based on usage scenarios:
  • Water-flush Type: Requires a water tank, flush valve, and sewage collection tank, suitable for scenarios with a water source;
  • Vacuum Suction Type: Uses a vacuum pump to rapidly suction waste, saving water and reducing odors, but with higher costs;
  • Dry Type: Includes packing type (using degradable bags) and biodegradable type (utilizing microorganisms to decompose waste), suitable for areas without a water source or with high environmental requirements;
  • Chemical Treatment Type: Disinfects and deodorizes by adding chemical agents, requiring regular replacement of treatment solutions.
• Auxiliary Function System: Covers lighting (LED energy-saving lights), ventilation (natural or forced exhaust), handwashing stations (equipped with water-saving faucets), water supply and drainage piping (using PPR or PVC pipes), and signage systems (luminous signs), all complying with electrical safety and piping seal standards.

2. Regional Industrial Support
As a manufacturing base, Jiangjin District has a complete industrial chain in metal processing, enabling efficient cutting, forming, and surface treatment (such as spraying anti-corrosion paint) of structural frameworks. The steel and non-ferrous metal industries in Chongqing and surrounding areas (such as Pangang and Chongqing Steel) provide a stable supply of framework and enclosure materials, while the chemical materials industry (such as Sichuan Vinylon Works) supports the production of auxiliary materials like sealants and anti-corrosion coatings. Additionally, the sanitary ware (such as Arrow and Hengjie) and general component (such as valves and fittings) production bases in the Sichuan-Chongqing region reduce procurement costs and logistics cycles, forming a production advantage of "localized support - rapid response".

3. Processing Flow and Quality Control
The processing flow typically includes: design drawing review → material procurement and inspection → framework welding/riveting → enclosure panel installation → sanitation system debugging → auxiliary function integration → finished product testing (such as load testing and airtightness testing). Key quality control points include: mechanical property testing of metal materials, fire rating verification of composite panels, sewage system seal testing, and electrical safety insulation testing, ensuring products comply with the "Urban Public Toilet Design Standard" (CJJ 14-2016) and local environmental requirements.
