Fiberglass reinforced plastic roof panels are a new type of building material that has been widely used in the construction field due to its advantages such as lightweight, high strength, corrosion resistance, and good insulation performance. However, as a common roofing material, fiberglass roof panels also have some safety hazards, such as fire prevention issues. This article will discuss the fire resistance performance of fiberglass roof panels.
1、 Fire resistance performance of fiberglass roof panels
Fire rating
According to the national standard "GB8624-2012" and "Classification Method for Burning Performance of Building Materials", fiberglass roof panels belong to non flammable materials, and their fire resistance rating reaches B1 level, indicating that the material is not easy to burn, has a low degree of combustion in fires, and does not produce a large amount of harmful gases and smoke, making it easier for people to escape.
Flame diffusion performance
The flame diffusion performance of fiberglass roof panels is considered an important safety indicator. According to the GB/T8626-2017 "Methods for Flame Spread Testing of Building Materials and Products" standard, this material is divided into three categories based on its flame spread performance: B1, B2, and B3. Among them, Class B1 represents refractory materials that do not produce a large amount of flames and harmful gases in fires; Class B2 represents combustible materials, but their combustion speed is slow and flames are not easily spread; Class B3 represents flammable materials, which have a fast combustion rate and are prone to flame spread.
The fiberglass roof panel has undergone relevant tests and its flame diffusion index is B1, indicating that the material is not prone to flame spread in fires and meets the requirements of relevant national fire prevention standards.
Flame resistance performance
Flame resistance is a measure of a material's ability to resist combustion and is one of the important indicators for evaluating its fire resistance performance. At present, there is no specific standard for the flame resistance of fiberglass roof panels at home and abroad, and the flame resistance of this material is influenced by various factors, such as resin type, filler quality, fiber cloth thickness, etc.
2、 Methods for improving the fire resistance performance of fiberglass roof panels
Select high-quality materials
In order to improve the fire resistance of fiberglass roof panels, it is first necessary to choose high-quality fiberglass cloth and resin. At present, there are various types of fiberglass roof panel materials on the market, with varying quality. High quality fiberglass roof panels should be made of high-quality fiberglass cloth and resin, which can help improve their fire resistance performance.
Add fillers
Fillers are an important component of fiberglass roof panels. Increasing the proportion of fillers can effectively reduce the combustion performance of the material. Some available fillers, such as aluminum oxide, aluminum silicate, expanded perlite, etc., can reduce the burning speed and fire prevention effect in the glass sheet.
Increase the thickness of fiber cloth
Fiber cloth is one of the main components of fiberglass roof panels, and the thicker it is, the better the fire resistance of the material. Therefore, the thickness of fiber cloth can be increased during the production process to improve the fire resistance level of fiberglass roof panels.
Spray fireproof coating
Spraying fireproof coatings is a relatively simple and effective method that can increase the fire resistance of fiberglass roof panels. This coating has fire-resistant properties and can form a protective layer, making the fiberglass roof more fireproof.
Pay special attention to electrical equipment
When installing and using fiberglass roof panels, special attention should be paid to the installation position and protective measures of electrical equipment. Electrical equipment is prone to fire, so electrical appliances should be insulated and placed in a safe area to ensure the normal operation of the equipment and reduce the possibility of fire.
3、 Fire protection application of fiberglass roof panels
The fire resistance performance of fiberglass roof panels has received widespread attention and application. According to different usage environments and needs, different types and grades of fiberglass roof panels can be selected to meet the fire protection requirements of buildings.
For example, in public places, commercial buildings, large factory workshops and other places, it is necessary to choose fiberglass roof panels with higher fire resistance levels and better fire performance; In relatively small areas such as residential areas and small offices, fiberglass panels with lower fire protection ratings and higher prices can be used.
In short, fiberglass roof panels, as a new type of building material, have advantages such as lightweight, corrosion resistance, and good insulation performance. However, their fire resistance performance is also an issue that we need to pay attention to. By selecting high-quality materials, increasing fillers, increasing the thickness of fiber cloth, spraying fireproof coatings, and paying special attention to electrical equipment, the fire resistance performance of fiberglass roof panels can be effectively improved, reducing the possibility of fire. In future work and production, we should pay more attention to the fire prevention of fiberglass roof panels, continuously improve their safety performance, and achieve the goal of building safety and sustainable development.
