Flame retardant plywood is a kind of board that has five characteristics: flame retardancy, smoke suppression, corrosion resistance, insect resistance and stability, and is very practical. It maintains the excellent physical properties, processing performance and decorative functions of traditional wood-based panels. Flame retardant plywoods are widely used in public construction and decoration projects such as hotels, convention and exhibition centers, sports centers, libraries, transportation passenger centers, leisure and entertainment venues, shopping malls, medical institutions, offices, high-end residential construction and decoration projects, and high-end furniture manufacturing projects.
The fire-retardant coating itself is difficult to burn or non-combustible, so that the protected combustible substrate does not come into direct contact with the air and delays the ignition and combustion of the substrate;
The fire-retardant coating decomposes into non-combustible inert gas when exposed to fire and heat, which dilutes the flammable gas and oxygen in the air decomposed by the protected substrate when heated, inhibiting combustion;
The fire-retardant coating generates free radicals that slow down and terminate the combustion chain reaction when exposed to heat;
The fire-retardant coating expands when exposed to heat, forming a heat-insulating and oxygen-isolating expanded carbon layer to prevent the substrate from igniting and burning.
Factors affecting the price of flame retardant plywoods:
Different flame retardant boards have different thickness specifications, and their sales prices are also different.
1.The thicker the flame retardant plywood, the higher its fire resistance index is relatively, and its production cost is relatively higher than that of ordinary flame retardant plywoods.
2.The prices required for flame retardant plywoods made of different materials are different. Flame retardant plywoods made of high quality materials are definitely more expensive than ordinary.
3.The prices required for flame retardant plywoods with different fire resistance levels are different. The grades of flame retardant plywoods are divided into: Grade A, Grade A1, Grade B, Grade B1. The higher the fire resistance grade of the flame retardant plywood, the higher the price required.
Fire retardant plywood fire rating classification:
Fire rating A: A is a non-combustible material. The flame retardant rating of A is very high, and the price is also quite expensive.
Fire rating B: B is a flame retardant material. Generally, high-end public places are decorated with this material.
Fire rating B1: B1 is a non-combustible material. It is combustible, but not easy to burn. It has a certain fire retardant effect in fire retardancy. This type of plywood is generally used in low-end public places.
Flame retardants are divided into two types: ignition type and flame-retardant type. The function of ignition type flame retardants is to release compounds to absorb heat and cool down the material when it burns, thereby preventing the fire from spreading; the function of flame retardant type is to make the material itself have flame retardant properties, it is difficult to undergo a combustion reaction when burned.
Application fields of flame retardant boards
Flame retardant plywoods are widely used, mainly in the following fields:
1.Construction: Flame retardant plywoods can be used as indoor walls, ceilings, and outdoor balconies and exterior walls
2.Transportation: Flame retardant plywoods can be used for interior 3.Security: Flame retardant plywoods can be used in fire partitions, insulation layers, improve building safety performance.
4.Decoration: Flame retardant plywoods can be used in home decoration, commercial space decoration, exhibitions and other fields to enrich space design.
Maintenance and care of flame retardant plywoods
Flame retardant plywoods need regular maintenance and care to improve their fire resistance and service life.
1.Prevent mechanical impact: Flame retardant plywoods cannot be subjected to mechanical impact for a long time to avoid cracks, deformation and other defects on the board.
2.Prevent rainwater penetration: Flame retardant plywoods need to be strengthened with rain protection to prevent rainwater from penetrating and damaging the board.
3.Regular cleaning: Clean the flame retardant plywoods regularly to prevent dust accumulation, corruption and other corrosion of the board, affecting the service life.
4.Prevent acid rain corrosion: Flame retardant plywoods need to be regularly treated with acid rain protection to prevent the board from being corroded by acid rain.
5.Process fire retardant coatings: Flame retardant plywoods need to be processed with fire retardant coatings regularly during use to improve their fire resistance level and durability.
