Rapid detection method for fire resistance duration of fireproof wooden doors taking expanded perlite plates as core plates

Abstract

The invention provides a rapid detection method for fire resistance duration of fireproof wooden doors taking expanded perlite plates as core plates. The rapid detection method comprises the following steps that 1, the expanded perlite plates are pretreated and then placed into a non-combustibility test furnace for a combustion test, each set comprises M expanded perlite plates of which the densities are same and the combustion thicknesses are sequentially increased, the densities of the expanded perlite plates are sequentially increased N times, combustion of the non-combustibility test furnace is timed, and the state in the furnace is recorded; 2, combustion heat value measurement is conducted on each set of the expanded perlite plates; 3, fire resistance duration of the fireproof doors made of the expanded perlite plates is tested, linear regression analysis is conducted to generate linear regression models of the fireproof door fire resistance duration time and the densities and the thicknesses of the core plates of the fireproof doors, and an error between fire resistance duration calculated by the linear regression models and a result practically measured by adopting a standard method is within 10 min. The method can be applied to rapid detection on fire resistance duration of the fireproof wooden doors and has very good scientific research and practice values.

Description

technical field [0001] The invention relates to the field of fire safety detection, in particular to a rapid detection method for the fire resistance limit of a wooden fireproof door with an expanded perlite board as a core board. Background technique [0002] The fire door is a kind of fire partition with special functions such as fire prevention, smoke insulation, and high temperature resistance. It can prevent the spread of fire and smoke diffusion within a certain period of time, and is an effective protective barrier for escape routes. The fire doors on the market are mainly wooden fire doors and steel fire doors. Among them, wooden fire doors are widely used because of their light weight, easy installation, and good decorative effects. However, with the increasingly fierce market competition, there are more and more shoddy products, posing a greater fire hazard. How to quickly detect the fire resistance limit of wooden fire doors and prevent inferior products from ent...

Problems solved by technology

This method requires a large experimental site, cumbersome and time-consuming installation, high gas consumption, expensive professional testing equipment, fuel consumption, and high testing costs, so it is not suitable for popularization and use.

At present, there is no relevant method for rapid detection of wooden fire doors at home and abroad.
