1. Other situations in which the color steel sandwich panel increases the risk of fire: (1) The fire may spread concealed in other directions through the EPS in the double-layer color steel plate without being discovered.
PVC is the most widely used member of the vinyl family. Common applications include chemical processing tanks, valves, fittings & piping systems. PVC The outstanding performance of PVC includes high mechanical strength, high hardness, good chemical resistance, electrical insulation, good printing and welding. PVC modified varieties including high polymer PVC, chlorinated PVC and PVC / ABS alloy. It`s working temperature is 0℃~+70℃.

Color steel sandwich panel fire hazard knowledge
1. Other cases of increased fire risk of color steel sandwich panels:
(1) The fire may spread concealed in other directions through the EPS in the double-layer color steel plate without being discovered.
(2) The EPS color steel sandwich panel itself may greatly increase the fire load of the building. According to the relevant information, the fire load caused by the 0.05m thick foam core material commonly used in sandwich panels may increase the fire load of the entire building by 9% to 30%. In some buildings that require extensive use of combustible material sandwich panels to enhance insulation (such as the cold storage of the food industry), the fire load on the sandwich panels themselves may even be 1.5 times the fire load caused by other items in the building.
2. The EPS color steel sandwich panel threatens the trapped and rescued personnel in the fire.
(1) Toxic gases such as CO produced by the combustion of EPS sandwich panels are a major threat to escape or rescue personnel in fire buildings. CO is the main cause of death in fires. CO is absorbed by the blood through the lungs. Because the affinity of hemoglobin for CO is greater than the affinity for O, the oxygen content in the blood is reduced, resulting in insufficient oxygen supply, which can easily poison the people present. Died.
(2) The black smoke generated by the EPS color steel plate burning weakens the visibility of the fire field, causing great inconvenience to the visual personnel, and even directly affects the development of escape and rescue work.
(3) EPS color steel sandwich panels have low fire resistance and are easy to collapse, posing a serious threat to the safety of the personnel present.
(4) The EPS color steel sandwich panel is not easy to be dismantled. After the collapse, it is very inconvenient for the fire field search and rescue, the fire fighting operation, and the fire cause investigation.
