Sheet Materials for Mobile Toilets in Changchun

The sheet materials used for mobile toilets in Changchun mainly include stainless steel, galvanized steel sheets, reinforced sanitary-grade EPS sheets, fiberglass-reinforced plastic (FRP), PVC sheets, color-coated steel sheets, and anti-corrosion wood materials, among others.

Stainless steel has extremely strong corrosion resistance, making it highly suitable for long-term exposure to outdoor environments. Under Changchun's climatic conditions, whether it is humid air or possible chemical substances, it is difficult to erode stainless steel sheets, thus ensuring the long-term stable use of mobile toilets.

When using galvanized steel sheets, it is essential to pay close attention to the thickness of the galvanized layer and the presence of anti-rust coatings. Their surfaces are arranged with polar metal atoms, which have stronger adsorption for water molecules and common organic stains, especially at seams or welds where dirt is more likely to accumulate. Therefore, mobile toilets using galvanized steel sheets require more frequent cleaning with chemical cleaners to maintain hygiene.

Reinforced sanitary-grade EPS sheets are commonly used for the walls of mobile toilet restrooms. These sheets provide ample space for the fecal storage tank, allowing for a large amount of fecal storage with minimal odor, without causing environmental pollution, and providing users with a more comfortable and hygienic environment.

Fiberglass-reinforced plastic (FRP) is composed of a resin matrix and glass fiber reinforcement materials, with internal fibers arranged in a mesh pattern. This structure effectively disperses external impacts, and its overall expansion coefficient is relatively uniform during temperature changes, resulting in a low probability of structural deformation. Therefore, components such as doors and partitions made of FRP are less likely to undergo professional deformation or misalignment, ensuring the structural stability of mobile toilets.

PVC sheets are used for internal splicing in mobile toilets, with special sealants applied at the seams. This treatment effectively prevents sewage leakage, ensuring the cleanliness and hygiene inside mobile toilets.

Color-coated steel sheets and anti-corrosion wood materials are mostly used on the exterior of mobile toilets, with polyurethane waterproof coatings applied to their surfaces. This coating not only prevents rainwater leakage but also resists erosion from construction site dust and chemical substances, thereby extending the service life of mobile toilets.
