Introduction to the Fire Resistance of Rock Wool Sandwich Panels in Container Prefab Houses
Most container mobile board houses consist of color-coated steel sheets and a core of EPS or polyurethane. The outer layer is usually bake-coated galvanized steel sheet. The EPS core is a closed-cell rigid foam made from sticky polystyrene beads; it has a low ignition point, burns easily, and is highly toxic. In addition, color-coated steel transfers heat very quickly and has poor fire resistance. So how can we prevent fires in container mobile board houses, and how should we use these convenient structures correctly? Today I summarize the following five points for your reference:
Organizations should earnestly implement the fire safety responsibility system, train employees in fire safety, and raise fire safety awareness.
When board houses are used as dormitories, doors and windows should remain openable, beds should not be packed densely, and safe evacuation routes should be left.
Fire extinguishers, hydrants, and other emergency fire equipment should be installed inside and outside prefabricated board houses according to relevant regulations, and inspected and maintained regularly as required to ensure they work properly.
Strengthen daily fire safety management of container mobile board houses. Prohibit high-power electrical appliances inside board houses, and cut off all power promptly when leaving. Open flames are strictly forbidden in rooms, kitchens, electrical distribution rooms, and warehouses for flammable or explosive materials.
Care must be taken in laying electrical wiring. All wires should be exposed and covered with flame-retardant conduit. Keep a safe distance between lamps and walls. Fluorescent lighting should use electronic ballasts; coil inductive ballasts should not be chosen. Where wires pass through color-steel sandwich panel walls, they must be sheathed with porcelain tubes or other non-combustible plastic tubes. Each board house should be fitted with qualified residual-current (leakage) protection and short-circuit/overload switches.
Container mobile board houses still differ from traditional homes in floor area and overall scale. Ordinary houses can be built as large as we wish—given sufficient funds, a seven- or eight-story building is no problem. Mobile board houses, however, are limited in area and form; they are not as large as you might want. So how can we make better use of space in a container mobile board house, and even make the interior look larger? Let us discuss this in the context of mobile board houses.
Furniture inside a container mobile board house should be light and simple, because furniture already takes up considerable space. Placing a lot of bulky furniture indoors creates a cluttered, crowded, and narrow feel. Visually, cool colors and white can be used to make the interior bright and spacious. Imagine a space that is already small: dark finishes only make it feel more oppressive. Mirrors also help optically; installing them can make the house look as if special effects had expanded it.
