How to Choose Tiles for Mobile Toilets in Shanghai

When selecting tiles for mobile toilets in Shanghai, it is crucial to focus on slip resistance and water absorption rate, and to distinguish between floor tiles and wall tiles for their respective uses.

Slip Resistance is a Core Requirement

Mobile toilets are often in humid environments, posing a high risk of slippery floors. Therefore, floor tiles must have strong slip-resistant properties. The surface texture and patterns of slip-resistant tiles can increase friction, effectively reducing the likelihood of slipping. For example, matte tiles, with their imitation of natural rock's unevenness, offer better slip resistance than ordinary glossy tiles, making them particularly suitable for scenarios involving the elderly, children, or individuals with mobility impairments. Additionally, materials with rough surfaces, such as full-body tiles and mosaic tiles, can also serve as alternatives, but it is essential to ensure that their slip resistance levels meet public safety standards (e.g., a friction coefficient ≥ 0.6).

Water Absorption Rate Must be Strictly Controlled

Floor tiles should be porcelain tiles with a water absorption rate below 0.5% to prevent water vapor penetration, which can cause tile expansion, detachment, or mold growth. Tiles with high water absorption rates, such as ceramic tiles, are prone to absorbing stains, making cleaning difficult, and may develop odors due to prolonged exposure to moisture, making them unsuitable for mobile toilet floors. Although wall tiles have a higher water absorption rate (typically 3%-12%), their rough back design is only suitable for wall adhesion. Misusing them as floor tiles can lead to breakage due to insufficient load-bearing capacity, so floor and wall tiles must not be mixed.

Material and Construction Adaptability

Floor tiles need to be wear-resistant to withstand frequent use and friction from cleaning tools. It is recommended to choose full-glazed polished tiles or vitrified tiles, which are hard, corrosion-resistant, and easy to clean with a smooth surface. For wall tiles, glazed tiles can be selected, as they have moderate water absorption and good stain resistance. However, it is important to use special tile adhesive during construction to ensure firm adhesion. Additionally, it is advisable to choose medium or small-sized tiles, such as 300mm×300mm or 600mm×600mm, to facilitate adjusting the drainage slope and preventing water accumulation.

Maintenance and Safety Details

Daily cleaning should avoid using strong acid or alkali cleaners to prevent corrosion of the tile surface. If the floor shows signs of wear or reduced slip resistance, tiles should be replaced promptly or anti-slip mats laid. Meanwhile, the drainage system of the mobile toilet should be designed in conjunction with the tile laying slope (usually 1%-2%) to ensure rapid drainage of sewage and further reduce the risk of slipping.
