FIRE PROTECTION OF METAL CONSTRUCTIONS BY A BLOATED COATTNG

Анотація

Abstract A composition of the effective bloated coating for the protection of metal, particularly aluminum constructions from the fire was developed. Fiat and shaped covers and platting (covers) used in civil engineering were testing. The components of the construction were made of the AMg-62T aluminum alloys. The testing was being carried out in the fire chamber complying with the ISO 834 International standards requirements. The limit of fire resistively for aluminum elements it was equaled one hour. A technique for calculating the limit of fire resistively for metal constructions protected by a bloated coating is suggested.
