Description

Technical Field

[0001] The utility model relates to the technical field of fire prevention detection, in particular to a fire prevention performance detection device for building materials. Background Art

[0002] Fireproof materials are materials that have the ability to prevent or block the spread of flames and are often used for fire prevention. Fireproof materials are divided into two categories: non-combustible materials and flame-retardant materials. Non-combustible materials will not burn. Although flame-retardant materials can burn, they are flame-retardant, that is, they are difficult to ignite and carbonize. The combustion can stop after the fire source is removed, so they are also called flame-retardant materials. Among flame-retardant materials, except for a few that have flame-retardant functions themselves, in most cases, they are made by flame-retardant treatment of flammable materials with flame retardants, fire-retardant impregnants or fire-retardant coatings. From the perspective of fire safety, fireproof materials should be used as much as possible in civil engineering to replace flammable materials to reduce fire load and reduce the speed of fire spread.
