Special waterproof and fireproof design is required in container construction, especially in the aspect of fireproof design, because its space is relatively small and tightly sealed. Once a fire occurs, it will cause a large number of casualties and property losses, so container manufacturers Establish protection mechanisms, in addition to considering safety aspects, they will also focus on waterproofing.
1. Waterproof membrane
After cleaning the base layer, brush the adhesive on the reverse side of the coil and the base layer, and paste and roll from far to near according to the elastic reference line, and then do the seam end inspection treatment. After the completion of the water storage experiment. Container manufacturers will have different differences in the insulation materials used for thermal insulation according to the environmental climate of the project site. The walls / ceilings of container houses designed by container manufacturers will generally use Ou Song board, gypsum board, cement fiber board, high Decorated with molecular assembly board, aluminum alloy carved board, anti-corrosion wood, etc .;
2. Waterproof coating
Take "one cloth and two coatings" as an example: after cleaning the base layer, brush the coating once, and after drying to form a film, lay a layer of glass fiber cloth matrix reinforcement material, and then apply a layer of paint on the flattened surface to fix The container manufacturer reminded to carry out the next roof waterproof construction after drying. The inside of the container is sprayed with polyurethane foam, and glass rock wool board is installed to prevent moisture, corrosion, heat insulation and sound insulation. Air conditioners are installed indoors in the south, and floor heating is installed in the north; reputable container manufacturers strongly recommend that the outer layer be covered with decorative materials, such as Ou Song boards, gypsum boards, cement fiber boards, polymer assembly boards, etc.
3. Laying a rigid waterproof layer
Professional container manufacturers said that construction should be carried out about two days after the completion of the first flexible waterproof layer, mainly using high-grade fatty acid mortar waterproofing agents, cement, sand, fine aggregate, and fiber as the basic materials. The thickness of the waterproof layer should be based on Container manufacturers require mainly. In order to meet the fire and heat insulation requirements of the wall and ceiling, the container manufacturer recommends that glass rock wool sandwich panels with a standard thickness be used for decoration.
According to container manufacturers, some high-rise container houses may also add multi-layer color steel plates or aluminum plates to achieve wind insulation and waterproof effects. The specific external waterproof method needs to be based on the structural keel installed at the top. Decided, but most manufacturers will apply glue outside the protective layer, which can effectively prevent ultraviolet rays and prevent water leakage.
