The main component of industrial fire blanket glass fiber cloth is glass filament, which is an inorganic non-metallic material treated by a special process.
Main ingredients:
The basic material of glass fiber cloth is alkali-free glass fiber yarn, which is processed by high-temperature melting, wire drawing and weaving. These fiber filaments are mainly composed of silicon dioxide (SiO₂) and other oxides, and have high thermal and chemical stability.
Impact on the performance of fire blankets:
High temperature resistance: Glass fiber cloth can maintain structural stability in high temperature environments and is not easy to melt or burn. This allows the fire blanket to quickly isolate oxygen when it comes into contact with flames, achieving the effect of suffocating fire.
Insulation performance: Glass fiber cloth has good insulation properties, which can effectively prevent the passage of current and reduce the risk of secondary disasters caused by electrical equipment in fires.
Lightweight and high strength: Glass fiber cloth is light in weight but high in strength, allowing the fire blanket to be easily operated when covering the fire source while maintaining sufficient strength to isolate flames and heat.
Chemical stability: Fiberglass cloth has good stability to most chemicals and is not easily corroded or decomposed, thus maintaining the long-term effectiveness of the fire blanket.
Flame retardant performance: When fiberglass cloth encounters flames, its fiber material will undergo thermal decomposition, releasing non-combustible gases, forming a protective layer to prevent the further spread of flames.
Issues to note:
Although fiberglass cloth has good fire resistance, its fire resistance may be reduced under certain extreme high temperature conditions. For example, under high temperature conditions, some flame retardants may fail, resulting in reduced fire resistance.
The thermal insulation performance of fiberglass cloth is relatively limited, so in some occasions where higher thermal insulation requirements are required, it may need to be used in conjunction with other thermal insulation materials.
The main component of industrial fire blanket fiberglass cloth is glass fiber, and its high temperature resistance, insulation, light weight, high strength and chemical stability have an important impact on the performance of the fire blanket. However, in practical applications, it is also necessary to pay attention to the reduction of its high temperature fire resistance and the relatively limited thermal insulation performance.
