The environmentally friendly "tunnel fireproof coating" is mainly composed of inorganic mineral insulation materials. The fireproof coating manufacturer has the characteristics of non-toxic and odorless, easy construction, strong coating adhesion, long fire resistance time, and stable fire resistance performance. The commonly used base material of tunnel fireproof coating must also be fire-resistant and thermal insulation materials, which are required to have low relative density, low thermal conductivity, good high-temperature stability and other characteristics, such as expanded perlite, rock wool, melamine foam, etc. Tunnel fireproof coatings are mainly suitable for fire prevention in highway tunnels and railway tunnels, as well as for fire prevention needs in petrochemical engineering, high-rise buildings, steel structures, and underground parking garages. At present, many manufacturers are actively researching and applying tunnel fireproof coatings. With the advancement of these works, more and better tunnel fireproof coating products will emerge to meet the needs of society. This can promote the development of tunnel fireproof coatings, leading them towards a good development track and ensuring the implementation of railway traffic safety.

Why do we choose Jiangxi Youlinsheng fireproof coating? According to the fire-resistant coating editor, although the main building inside the tunnel is made of non combustible materials such as reinforced concrete, due to the airtightness of the tunnel, the temperature of the tunnel fire rises rapidly and lasts for a long time after combustion, making it difficult for firefighters to enter and implement firefighting. Within a short period of time after a fire occurs, the temperature of the fire is more likely to cause the concrete surface to explode, resulting in significant collapse. This further exacerbates the danger to the lives of evacuation and rescue personnel, resulting in significant direct and indirect losses.

How to check the quality of Jiangxi Youlinsheng fireproof coating? The Guizhou fireproof coating editor tells you that you can conduct a preliminary inspection of the product quality on site: cut 2-3 small samples from the already constructed substrate, or take a small amount of samples and apply them to 2-3 150mm x 150mm plywood, and apply according to the actual construction situation. After drying completely, check with the flame of an alcohol lamp. The flame height is about 40mm, and the application time of the flame is generally 20min. Check the foaming condition of the coating. According to Guizhou fireproof coating manufacturers, under normal circumstances, construction should be carried out according to the prescribed dosage (usually 500 grams per square meter). The thickness of the foam layer of the first level fireproof coating should be 20mm or more, and the thickness of the foam layer of the second level fireproof coating should be 10mm or more. The foam layer should be uniform and dense. Qualified fire-resistant coatings will undergo significant foaming and expansion when exposed to strong flames such as blowouts, resulting in surface aggregation and protrusions that will not cause burning damage within a few minutes. On the other hand, counterfeit and inferior fire-resistant coatings will not foam at all and will result in a large amount of scattering and debris. Wooden substrates will also quickly experience burning and damage.

Check whether the product has a qualified inspection report issued by the Fire Quality Inspection Center, or you can search online. Fireproof coatings shall implement a fire protection product type approval system, and the fireproof coatings sold on the market shall have a national fire protection product type approval certificate and a type inspection qualification report.
