Mobile Toilet Continuous Sandwich Panel

The commonly used continuous sandwich panels (sandwich boards) for mobile toilets mainly include color-steel sandwich foam panels, rock wool sandwich panels, and polyurethane sandwich panels. Each type has its own characteristics, and some products can be customized.

1. Color-Steel Sandwich Foam Panels Color-steel sandwich foam panels are a cost-effective choice for wall materials in mobile toilets. Their structure consists of two layers of color-steel plates with foam material filled in between, offering advantages such as light weight and easy installation. They are suitable for scenarios where cost is a concern and fire safety requirements are not high. However, it should be noted that the fire resistance of such materials is relatively poor. The foam material is prone to burning at high temperatures and may release toxic gases, making them unsuitable for crowded public places or those with strict fire safety regulations.

2. Rock Wool Sandwich Panels Rock wool sandwich panels use rock wool as the core material, with an outer layer of metal panels (such as galvanized steel plates). They achieve a Class A fire rating (non-combustible) and are the preferred material for mobile toilets in public places. Rock wool itself has excellent thermal insulation and sound insulation properties, effectively reducing noise interference. It is also heat-resistant and has low moisture absorption, preventing structural damage caused by dampness. For example, the sound-insulating and noise-reducing rock wool sandwich metal fireproof integrated panel provided by Chaoyang, Liaoning, is priced at 36.00 yuan per square meter, balancing fire safety and functional requirements.

3. Polyurethane Sandwich Panels Polyurethane sandwich panels use polyurethane foam as the core material, with an outer layer often made of colored coated steel plates. They combine thermal insulation, moisture resistance, and aesthetic appeal. The closed-cell structure of polyurethane results in a low thermal conductivity coefficient, providing better thermal insulation than rock wool. They are suitable for mobile toilets in cold regions or those with high temperature control requirements. Additionally, their smooth surface and diverse colors enhance overall aesthetics. For example, the rigid PU sandwich panel produced in Yancheng, Jiangsu, is priced at 100.00 yuan per square meter and offers multiple functions such as waterproofing, fire resistance, and sound insulation, but at a relatively higher cost.

Customization Options Some suppliers offer customization services for sandwich panels, allowing adjustments to material thickness, dimensions, or functions based on the specific needs of mobile toilets. For example, adding fire-resistant coatings, optimizing sound insulation structures, or applying special surface treatments (such as corrosion resistance or antibacterial properties). Although customized products may be more expensive, they can more precisely match usage scenarios and extend the lifespan of facilities.

Summary: The selection of sandwich panels for mobile toilets requires comprehensive consideration of factors such as cost, fire resistance, thermal insulation, and sound insulation. Color-steel sandwich foam panels are suitable for cost-sensitive scenarios; rock wool sandwich panels are the safe choice for public places; and polyurethane sandwich panels are ideal for environments with high thermal insulation and aesthetic requirements. Customization services can further meet personalized needs.
