Why do large-scale projects choose fire-retardant boards? Four major functions of fire-retardant boards!

The construction of large-scale projects relies heavily on the use of various materials, and fire-retardant boards, as an important building material, are widely used in large-scale projects. Why are fire-retardant boards chosen for large-scale projects?

I. Enhancing Building Safety – Class B1 Fire-Retardant

Fire-retardant boards have high flame retardancy and can effectively prevent the spread of fire, thereby reducing the possibility of fire.

The new type of flame-retardant OSB board perfectly achieves B1 flame retardancy rating, possessing excellent flame-retardant properties. When the board is heated, the microcapsules on the surface of the shavings rupture, absorbing heat and releasing highly efficient flame-retardant factors that dilute the concentration of combustibles in the combustion zone, effectively inhibiting the spread of flames. After the microcapsules rupture, the carbonization and salinization products cover the surface of the shavings, preventing smoke from escaping and achieving a dual effect of flame retardancy and smoke suppression.

In large-scale projects, the safety performance of buildings is the primary consideration, and the use of fire-retardant boards can significantly improve the safety performance of buildings.

What is B1 flame retardant?

In national standards, the fire performance ratings of building materials and products are divided into four levels:

Class A non-combustible materials: Materials that are almost non-combustible.

Class B1 flame-retardant materials: have good flame-retardant properties. They are difficult to ignite, spread slowly, and stop burning after the ignition source is removed.

Class B2 flammable materials: These materials ignite immediately upon contact with open flames or high temperatures, easily causing the fire to spread. For example, common wooden products are highly flammable and pose a significant risk.

B3 flammable materials: extremely flammable, posing a great fire hazard.

II. Possesses superior stability – anti-leaking

The most prominent feature of the new flame-retardant OSB board is its stable performance. The microcapsule encapsulation technology effectively enhances the interfacial compatibility between the flame retardant and the shavings, thereby increasing the grafting rate of the flame retardant on the surface of the shavings. The flame retardant will not precipitate in humid environments, enhancing its resistance to leakage.

Laboratory tests showed that the flame-retardant OSB board did not leach any flame retardant after being placed in a humid environment at 25°C and 85% humidity for 28 days.

III. Improving Project Quality – Corrosion Resistance

The new flame-retardant OSB board, combined with microcapsule encapsulation technology, effectively encapsulates the flame retardant, isolating it from contact with metal parts. This effectively reduces the corrosive effect of the flame retardant on metal parts, comprehensively improves the corrosion resistance of the board, and enhances the service life and stability of the building.

IV. Improve the living environment; ENF-level health and environmental protection

The biggest concern is excessive formaldehyde levels, which can harm the health of oneself and one's family. Environmentally friendly building materials have become the first choice for people decorating new homes or improving their living environment.

The new flame-retardant OSB uses MDI adhesive with zero added formaldehyde, meeting the highest national standard for formaldehyde emission, ENF level. Therefore, it not only effectively protects people's lives and property but also benefits environmental protection and health.

The new generation of flame-retardant OSB board is made from imported pine wood sliced ​​into sheets, with upgraded anti-corrosion properties. It is an environmentally friendly board with high flame retardancy, corrosion resistance, moisture resistance, and stable performance.

In summary, considering the advantages mentioned above, the use of flame-retardant OSB boards in large-scale engineering construction can build the first line of defense for life safety in the event of a fire, safeguarding the lives and property of you and your family.
