【 摘 要 】

Automatic fire curtains are designed to divide sections of premises and structures into fire compartments for the purpose of localizing a fire, as well as filling openings in fire barriers. If a fire occurs due to a signal from a fire alarm sensor or a signal from a fire station, the blind automatically falls and locates the source of ignition. The paper presents the results of testing nine samples of fire curtains with an applied intumescent composition. Tests were conducted for 60 minutes before loss of sample integrity. The average temperature from the heated side of the sample reached 800 ∼ 1000 ° C. Depending on the sample, the temperature from the unheated side ranged from 70 ° C to 294 ° C. The best result was shown by a sample from a layer of needle-punched heat-insulating material with a thermal conductivity of 0.036 W/(m×K) placed between layers of foil and treated with water-based intumescent composition of silica material.
