Fireproof structures, protect your home against fire
The process of fireproofing structures will be useful to reduce the risk of fire and, in turn, slow the spread of fire. The increasingly stringent requirements on testing fire protection have made the substances used for this purpose are increasingly relevant time in order to strengthen the defense of the structures facing the spread of a fire. For the same reason, beyond its effectiveness to protect structures and people living within them from the threat of fire, flame retardants must meet certain requirements.
Among other things, these materials must be toxic and should not migrate, no i.e. should not release additional toxic combustion gases or corrosive. They should also be compatible with the environment and should not reflect negatively on the mechanical and product recycling properties.
In the case of systems fireproof protection traditional we find the so – called fire retardant additives can be mineral such as aluminum trihydrate (ATH). Thus, when the fire occurs, the water was originally built as a hydrate form; it will be projected to the outside. All this reaction will have a cooling effect on the one hand, and that the gases generated by the fire will be diluted in water on the other. During processing, the viscosity of component is increased considerably, also enhancing the weight thereof.
Moreover, the fire retardant systems operating from ammonium polyphosphate be responsible for the combustion process difficult from the solid phase. When the flames begin to spread through the building, ammonium polyphosphate rot in polyphosphoric acid, causing charring the surface.
This coal is responsible for protecting the entire surface of the component of heat from the effects of fire, thus interrupting the oxygen supply and thus the spread of flames.
Studies performed demonstrate that flame retardants based on phosphorus use comply with all regulations concerning efficacy density and toxicity of the combustion gas. Another benefit we can highlight these based on the aforementioned phosphorus systems, related to the possibility of generating a charge to the not inconsiderable 70% in the thermosetting resins.
With the latter that will be achieved it is significantly improve the properties of materials processing. This mechanism is much more effective than the physical release of water to which we alluded in earlier lines.
Similarly, more innovative alternatives based on phosphorus such as in tumescent systems, which in case of fire generates a foaming reinforced carbon layer, which will tend to enhance the whole insulating effect. At the same time, it is demonstrated by research about the flame retardants based on the use of phosphorus meet the standards for density and toxicity of combustion gas.
You guys had some knowledge the advantages that a process fireproofing of structures can contribute to building? What kind of flame retardants have used to protect your house against fire?
