What is fireproofing? How passive fire protection was applied in industries?

Fireproofing, also known as fireproof, is a term that describes the making of something that is either fireproof, non-combustible, or self-contained. Thanks to its versatility, it can be used a lot in the field of fire protection.

Application of fireproofing system and passive fire protection in many fields

Using materials to support fireproofing, among them is fireproof paint - a type of paint with the most effective and optimal fire resistance. Flame retardant paint acts as a material on the surface of the metal to help the metal avoid the impact of heat, avoid absorbing and emitting heat, increasing the possibility of fire spreading.

Using fireproof paint for buildings to reduce the serious impact of fire is one of the most used options. Not only helps protect property and life, but it is also one of the regulations that need to be followed about current fire prevention and fighting methods. In addition, this method is considered to be reasonably priced, simple to construct, and effective. Not only that, it also brings a lot of other benefits when applied.

1. Mechanism of action of fireproofing paint on material surfaces

Fireproof paint will have different effects when applied on different surfaces. To bring efficiency and ensure a safe construction process, it is recommended to strictly follow the instructions when applying on the surface of the material. However, no matter what the materials are, in general this fireproof paint has a mechanism of action, it will change a few factors such as heat resistance time, heat resistance (but not significantly).

The mechanism of action of this paint is that when it encounters a fire, it will create a layer of paint many times thicker than its original shape. Thanks to this coating, it helps to protect the material from flames, reduce heat absorption and dispersion, and reduce human and property damage.

Some specific features of fireproof paint:

Fireproof paint can swell when exposed to high temperatures and can be used for materials such as steel, wood, concrete, brick,...

It has the ability to prevent the spread of flame, blocking most of the heat of the fire when it comes into direct contact with the painted surface. It also helps protect property, buildings and equipment from deformation caused by fire.

Fireproof paint should only be applied indoors, if it is applied in outdoor conditions, it should be equipped with a roof so that the paint quality is not affected by rain or standing water.

To ensure the quality of the paint, it is recommended to apply an additional layer of epoxy or colored PU paint as required.

After the paint is finished, the paint screen will still be slightly soft, so it should limit the impact of hard objects on the painted surface.

2. Advantages of fireproofing when used for construction surfaces

Fireproof paint brings many benefits to buildings as well as construction surfaces, which can be mentioned as:

 

• Fireproof paint is usually suitable for all types of materials, not only is it affordable but it is also easy to implement.

• The level of heat resistance is very high, from a few hundred to thousands of degrees Celsius.

• When using the fireproof method, it still brings high aesthetics to the surface and the whole building.

3. Notes on applying fireproof paint and other fireproofing solutions

During the process of applying fireproof paint, sometimes the paint layer will encounter some small errors that affect the quality and aesthetics of the paint.

On the surface, you may encounter the phenomenon of paint being wrinkled, rough. The cause of this phenomenon is largely due to the substandard quality of the primer, while the solvent-based fireproofing reacts strongly with the primer layer, causing the paint surface to be wrinkled and rough. To fix it, users can use sandpaper, effervescent kova, scrubber, ... to grind and remove the rough and peeling surface, then use fireproof paint to repaint. Finally spray a thin layer of fireproof paint and continue to complete the remaining work.

After applying fireproof paint, the surface of the material appears honeycomb, rough or convex. The main cause may be because the solvent evaporates too quickly, the thick paint film cannot escape, so air bubbles or crow's feet are formed.

Solution for this problem is you can use sandpaper or effervescent to smooth the surface, then use fireproof paint to seal the pitted surface. It takes 4-8 hours to dry this layer, after this time, the user continues to mix the paint in accordance with the regulations and re-spray the treated surface.

The solution to fireproofing problems is one that should not be overlooked. Everyone needs to pay attention to fire prevention to avoid damage to people and property.
