Printed color coated sheet is widely used in all walks of life, because of its corrosion resistance, easy installation and other advantages, so it is very convenient to use. As a plate to use, we are worried about the problem of fire, and the phenomenon
of fire is often caused by improper use and storage. Here we will give you a brief introduction. Let's analyze it.
1. Understanding of fire hazard of printed color coatings is insufficient. It is made of color coated steel plate, and its core materials are mainly polystyrene, polyurethane and rock wool. The first two are polystyrene or polyurethane with different thicknesses sandwiched between two thin steel plates. Once the material is subjected to high temperature spark or open fire, it will burn immediately. Because of the honeycomb structure of the material itself, the contact surface with air is enlarged, and the burning is very fierce. In the process of extinguishing, water and extinguishing. The powder can only be sprayed on the outside steel plate, and can not directly act on the burning materials in the interlayer. The toxicity of the burning products is very high, which can easily cause casualties. This kind of material is very popular with investors or developers because of its relatively low cost. The latter is rock wool with different thickness between two thin steel plates. This material belongs to non-combustible material and has good fire and heat insulation effect. However, because of its relatively high cost, investors or developers are generally reluctant to use it.
2. There are inherent hidden dangers in some printed color coated board construction projects which have not been examined and accepted by fire protection. In the construction of some projects, fire protection design is not considered in the design, or although there is fire protection design, the construction process is not in accordance with the drawings, and after the completion of the project, there is no fire control acceptance, so that several links that can be checked are ignored.
3. Installation and improper use of electrical appliances are also important causes of fire. The causes of building fire are mostly directly related to the illegal use of electrical appliances, circuit aging, etc. Some are to install wires directly in the sandwich layer of the printed color coating board, some are to drill through the wall directly when the wires pass through the wall, drilling without sheath is easy to cause damage to the insulation layer of the wires and short-circuit fire.
In fact, besides insufficient understanding of fire knowledge, there is also a lack of timely grasp of correct use methods, which leads to the occurrence of fire, so we must pay attention to grasp the correct use methods and prevent the occurrence of fire when we use them. Fire phenomenon.
