Waterproof Baked Paint Mobile Toilet
Waterproof baked paint mobile toilets typically employ a metal frame combined with a special waterproof baked paint process, along with a multi-layer waterproof structural design, offering wind and rain resistance, corrosion resistance, and a long service life. The following provides an explanation from three aspects: material selection, painting process, and waterproof design:
In terms of material selection, galvanized steel is predominantly used. For example, the frames of Youxuan and Color Steel Ecological Public Toilets are welded from galvanized square tubes, while Dezhou Hongtu Metal Products Co., Ltd.'s mobile toilets adopt a galvanized steel frame structure. Galvanized steel forms a zinc layer on its surface through hot-dip galvanizing, effectively isolating air and moisture to prevent steel rust and corrosion, providing a sturdy and durable foundation for the mobile toilet, along with good wind resistance to adapt to complex outdoor environments.
Regarding the painting process, automotive-grade painting technology is often employed. The roofs of Youxuan and Color Steel Ecological Public Toilets are paired with automotive-grade painting processes, and the surface paint of the steel structure sentry boxes from Xinyi'an Electromechanical Equipment Co., Ltd. also uses automotive paint. Automotive painting is completed in a large automotive painting booth and undergoes multiple processes, including primer spraying, sanding, topcoat spraying, and high-temperature baking. This process results in a uniform and smooth paint surface with strong adhesion, offering not only excellent decorative properties but also forming a dense protective layer that effectively resists erosion from rainwater, ultraviolet rays, acids, and alkalis, ensuring no deformation for ten years and extending the service life of the mobile toilet.
In terms of waterproof design, a multi-layer waterproof structure is adopted. The roofs of Youxuan and Color Steel Ecological Public Toilets feature a double-layer waterproof design, including an SBS waterproof layer and asphalt shingles. The SBS waterproof layer has good elasticity and low-temperature resistance, effectively preventing rainwater penetration; the asphalt shingles further enhance the waterproof effect while serving a decorative purpose. The mobile toilets from Dezhou Hongtu Metal Products Co., Ltd. are designed to prevent water accumulation as a whole, with waterproof asphalt shingles laid on top and a reasonable slope design to allow rainwater to drain quickly, avoiding damage to the toilet from water accumulation. The sentry boxes from Xinyi'an Electromechanical Equipment Co., Ltd. adopt a special waterproof process, with sealing treatment at key parts such as steel structure connections to prevent rainwater from seeping in through gaps.
