When a fire alarm sounds, ordinary materials can instantly become flame accelerants. However, one type of board material can become a "fire-fighting hero"-flame-retardant plywood! Its exceptional flame-retardant properties have earned it a top spot in the building material market, serving as a safety guard for life and property. GB/T 18101-2024, the national standard for "Flame-Resistant Plywood," plays a key role in ensuring the safety performance of flame-retardant plywood. As an industry leader, Rabbit Baby participated in the development of this standard, leveraging its years of expertise and technical expertise. This standard serves not only as a yardstick for the quality of flame-retardant plywood but also embodies Rabbit Baby's unwavering commitment to safety.
Chapter.01
Combustion performance
A competition of "fire protection level" in the materials industry
In the world of building materials, fire resistance determines the status of the industry! National standards divide materials into four levels:
| grade | name | Skill characteristics | Danger Index |
|---|---|---|---|
| A-level | non-combustible materials |
The flame can't burn at all, zero open flame |
★ |
| Level B1 | Flame-retardant materials |
It has a "fire-proof barrier" that slows the spread of fire and extinguishes it as soon as it is evacuated.
|
★★ |
| Level B2 | combustible materials |
It will catch fire immediately when it encounters fire, which will easily fuel the fire. |
★★★ |
| B3 level | flammable materials |
It ignites at a touch, a fire accelerator |
★★★★ |
Among these, flame-retardant plywood that achieves B1 rating is the most noteworthy! It must meet two key performance criteria: a combustion growth rate index (FIGRA) of 0.4MJ ≤ 250W/s and a total heat release rate (THR600s) of ≤ 15MJ within 600 seconds. Simply put, it ignites slowly and releases minimal heat, buying valuable time for escape!
Chapter.02
Smoke production characteristics
Classification of "smoke makers" in fires
Did you know? 80% of fire casualties are caused by smoke! Materials are divided into three levels based on their smoke production capacity:
| grade | Require | explain | |
|---|---|---|---|
| S1 level |
Smoke generation rate index SMOGRA≤30m2/s2
|
The smoke generation rate is low, and the total smoke generation is relatively low, which hardly affects the vision. |
|
|
Test 600S total smoke generation TSP600s≤50m2
|
|||
|
S2 level |
Smoke generation rate index SMOGRA≤180m2/s2
|
The amount of smoke is moderate and will cause slight visual interference |
|
|
Test 600S total smoke generation TSP600s≤200m2 |
|||
| S3 level |
Not reaching s2 |
The air was filled with smoke instantly, with both the smoke generation rate and the total smoke generation volume being high. The scene instantly turned into a pitch-black chaotic maze. |
|
S1 flame-retardant plywood acts like a "smoke insulator", allowing escape routes to remain clear at all times during a fire.
Chapter.03
smoke toxicity
The invisible "deadly killer"
What is more terrifying than smoke is the "poison assassin" hidden in the smoke! Smoke toxicity can be divided into three categories:
| grade | Require | explain |
|---|---|---|
| t0 |
Reaching the semi-safety level ZA1 |
The smoke toxicity is relatively low and poses little threat to the human body |
| t1 | Reaching quasi-safety level 3 ZA3 |
The smoke may contain a certain amount of toxic components, but not to a highly dangerous level.
|
| t2 |
Does not reach ZA3 |
The flue gas may contain a large amount of toxic components, posing a serious threat to human health |
In the life-or-death race of fire, choosing the right material is like adding armor to your armor! Rabbit Baby flame-retardant plywood has successfully counterattacked with cutting-edge technology! It utilizes a dual flame-retardant process of "impregnation + adhesive layer," allowing the flame retardant to penetrate the pores of the wood. After authoritative testing, Rabbit Baby flame-retardant plywood has directly obtained three major certifications:
Combustion performance: B1 grade
Smoke production characteristics: s1 level
Smoke toxicity: t1 level
Whether it is home decoration or commercial place, choosing it is equivalent to insuring your safety!
After reading this, are you still hesitant about choosing fireproofing materials? Remember: in the face of fire, a 0.1 second difference can mean the difference between life and death! Choosing flame-retardant plywood that meets the GB/T 18101-2024 standard, especially an all-rounder like Bunny Baby, is the ultimate protection for life!
