Insulation sandwich panel can prevent fire from six aspects

 

First: use rock wool with good fire resistance as core material, which is the way to cure the root cause

 

Second: in the process of construction, the core material shall be kept away from open flame operations such as electric welding and gas welding

 

Third: in the process of use, some heat sources and fire sources shall not be close to the steel plate, and a certain distance shall be kept. If the kitchen is to be set in the color steel room, a temperature insulation layer shall be provided, and the wall shall be equipped with a fireproof rock wool insulation layer

 

Fourth: wires and cables are better not to pass through the core material. If it is necessary to pass through, protective sleeves, sockets and switch boxes shall be made of metal galvanized boxes and surface mounted methods shall be adopted

 

Fifth: simple fire-fighting equipment shall be equipped indoors and outdoors, and fire alarm shall be installed if conditions permit, so as to facilitate rapid evacuation of personnel

 

Sixth: a safe distance of at least 6 meters shall be kept between the color steel plate rooms. Although the filling material of the color steel plate room without strict fire-retardant treatment is flammable, it will not self ignite. Strict, scientific and effective management can keep the fire away from the filling material of the color steel plate room, which is one of the important ways to prevent the sandwich panel house from fire.
