Common terms for flame retardant fabric testing
Tag:
flame retardant fabric flame retardant fabric burning
Flame-retardant fabrics are widely used in petroleum, chemical, hotel and other industries. So how to choose Flame-retardant fabric is a problem for many people. Many times when we choose Flame-retardant fabrics, we check online, but we don’t understand many professional terms. The expression of these terms makes the burning phenomenon of Flame-retardant fabric more rigorous and intuitive. By learning and understanding the terms, we can clearly understand the status of the product. Let’s learn some professional terms below.
(1) Combustion: When combustible substances leave the fire source, the oxidation exothermic reaction occurs, accompanied by the phenomenon of flaming or flameless combustion zone luminescence. .
(2) Burning: When a flammable substance comes into contact with a fire source, it is a flameless ignition process in a solid state, accompanied by the phenomenon of luminescence in the combustion zone.
(3) Afterburning: After the burning material leaves the fire source, it still continues to burn with flame.
(4) Smoldering: After the burning substance leaves the fire source, it still continues to burn without flame.
(5) Flaming combustion: a gas phase combustion phenomenon accompanied by luminescence.
(6) Smoke combustion: a slow burning phenomenon with no visible light and usually smoke.
(7) Ignition temperature: Under specified test conditions, the lower temperature at which the material begins to continue burning is usually called the ignition point.
(8) Pyrolysis: Irreversible chemical decomposition of materials at high temperatures without oxidation.
(9) Droplets: high-temperature melting droplets of materials.
(10) Carbonization: The process of forming carbonaceous residue during pyrolysis or incomplete combustion of materials.
(11) Flame retardant: The property of a certain material to prevent, slow down or terminate flammable combustion.
(12) Flame spread: the expansion process of the flame front.
(13) Damage length: Under the specified test conditions, the maximum length of the material damage area in the specified direction, usually also called the char length.
(14) Limiting oxygen index (L0I): Under specified test conditions, the ratio of oxygen in the nitrogen-oxygen mixture required to keep the material in a burning state Low concentration.
