Non-combustible building materials, when exposed to flame high temperature in the air, they will be fired, charred, slightly combustible. They are usually inorganic materials. For example, marble, granite, terrazzo, concrete products, cement products, lime products, clay products, gypsum board, glass, ceramic tiles, steel, copper alloy, aluminum, etc. Talc Masterbatch

Non-flammable building materials, when exposed to flame high temperature in the air, they are difficult to ignite, carbonize, slightly burn. When the fire source is removed, the combustion slight combustion can stop immediately, usually organic inorganic composite materials . Such as fiber gypsum board, gypsum board, cement particle board, glass wool decorative sound-absorbing board, mineral wool decorative sound-absorbing board, perlite decorative sound-absorbing board, flame-retardant medium density fiberboard, flame-retardant plywood, aluminum foil composite material, flame-retardant Wood, rock wool decorative board, flame-retardant phenolic plywood, etc.

Combustible building materials, when exposed to flame high temperature in the air, will immediately catch fire slightly combust, can continue to burn slightly combust after removing the fire source. Such as all kinds of natural wood, wood-based man-made panels, bamboo, bamboo decorative panels, plastic veneer decorative panels, decorative veneer panels, semi-rigid PVC plastic flooring, wood flooring, composite wood flooring, PVC coiled flooring, polyester decoration Board, artificial leather, wall covering, non-woven wall covering, composite wallpaper, plastic wallpaper, natural material wallpaper, etc.

Flammable building materials will catch fire immediately when exposed to flame high temperature in the air, the flame spreads quickly. Such as organic materials such as plexiglass foam plastic.

Characteristics requirements of building fire protection materials

Materials must meet three conditions before they can burn, namely, ignition source, combustion-supporting substance combustible substance. Just destroy reduce one of them to prevent the material burning.

Therefore, there are many requirements for fireproof materials, such as material flame retardancy, fire resistance, fire resistance, fire resistance limit, etc. Flame retardancy refers to the addition of substances treatments to the material to inhibit its combustion, to significantly reduce delay the flame expansion of the material when it burns, like the fireproof effect of the fireproof coating is flame retardant.

Fire resistance refers to the ability of building components, accessories structures to meet the integrity, stability, thermal insulation of standard fire resistance tests within a certain period of time.

Fire resistance refers to the physical chemical changes of materials, products, components exposed to fire to maintain their original performance.

The fire resistance limit refers to the period of time the effect of fire to the loss of stability, integrity, thermal insulation of building components, accessories, structures under standard fire test conditions.
