As is well known, fire-resistant materials have good heat resistance and flame retardant effects, and even in the event of a fire, they have a certain degree of control over the situation. It is precisely because of this that fireproof coatings are widely used in tunnel construction. The main function of tunnel fireproof coating is to prevent and control the occurrence of fires in tunnels, and even if a fire occurs, it will minimize losses to the greatest extent possible. However, there are many precautions in the construction process of tunnel fireproof coatings. If not handled properly, it can greatly reduce the fireproof function of the coating. So, what are the techniques involved in the construction process of tunnel fireproof coatings? Let's take a look below. The first point is to confirm the authenticity of the tunnel fireproof coating. What does this mean? It is to ensure that the coating is a qualified product, and never choose low-quality or unqualified products.

In addition to the above, attention should be paid to whether there is water seepage on the concrete surface before construction. If there is water seepage, it must be treated before normal construction can proceed.

Furthermore, it is necessary to check the moisture content on the surface of the concrete. Because being too wet can easily cause detachment, which can result in wastage of the coating, and on the other hand, it cannot achieve the desired effect of tunnel fireproof coating.

 Tunnel fireproof coating is the guarantee of our safe passage. Nowadays, fire accidents continue to occur, causing serious consequences. Therefore, tunnel fireproof coating was born, mainly used to prevent and stop floods in tunnels. Since its use in tunnels, the safety inside tunnels has also been guaranteed. The construction conditions of tunnel fireproof coating are very important. Let's take a look together today.

Dao fireproof coating is 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. The construction of tunnel fireproof coating generally adopts a layered and spaced construction process, which is divided into the base layer (fireproof layer) and the surface layer (color layer) for construction. During the construction period and within 24 hours after construction, the ambient temperature shall not be lower than 4 ℃ to prevent freezing damage. In extremely dry and hot conditions, necessary maintenance conditions should be created to prevent the coating from losing water too quickly.

Tunnel fireproof coating is easy to use

1. Tunnel fireproof coating does not contain asbestos or harmful substances, and the coatings produced, used, and constructed have no irritating odors. During a fire, no toxic gases are released, and the smoke toxicity reaches AQ-1 level, which meets environmental protection requirements.

2. Prepared by the factory, packaged as a single component, mixed and stirred on-site for easy operation.

3. Direct spraying and coating construction, fast drying and curing.

4. Lightweight coating, strong adhesion, high strength, superior aging resistance and waterproof performance. Tianjin Tunnel Fireproof Coating
