In incidences of fire fighting, there are substances that are commonly used in order to reduce flammability of fuels or rather delays the combustion. An overview of fire retardant coatings will unfold these substances explaining the outside layer that cover them. This includes chemical agents, but may also include substances that work by physical action, such as cooling the fuels, such as fire-fighting foams and fire-retardant gels.
There are number of retardants types available in the market today for timber, wood and other components. They are being marketed as suitable for the treatment of the particular component. All made from different compositions to suit the needs of customers. This will be discussed as below.
Most firefighting tools use immunescent coatings whereby immunescent refers to is a matter that tends to swell thus experiencing a reduction in density and an increase in volume due to effects of exposure to heat. Usually, there are two types of immunescent namely hard char and soft char. Hard char is created with silicates and graphite of sodium making it fit for exterior fireproofing while soft char generates a light char that acts as a poor heat conductor therefore retarding any transmission of heat.
Melamine which is the expanding material, ammonium polyphosphate that is the source of acid and pentaerythritol that supplies carbon are the components that interact together to ensure that the expansion process of the intumescent coatings goes through. However, other components are normally added in order to develop the paint material goods, improve the build and facilitate faster drying as the above components are usually dipped in a water-borne polymeric tool.
The chemical process starts when heat is instilled and this makes the ammonia phosphate to produce acid of organic kind as it softens the polymeric binder. The blowing agent, melamine then undergoes decomposition to release a gas that facilitates the swelling of the mixture that initially was molten and the char solidifies so as to maintain insulation.
Heat is usually exerted so that it works in making soft the binder which is made up of polymeric during the chemical reaction and as a result, ammonia phosphate responsible for production of acid releases it in an organic. From this, the blowing agent is observed to decompose and releases a gas which later makes the molten mixture to swell, and then the char solidifies to facilitate insulation. Normally, intumescent can enlarge to about 100 times its initial wideness although this will happen if the equipment used for formulation are correctly selected.
Another method is saturation by topical application. Application is by brush, roller or spray and usually requires 2-3 coats. This too can be a very cost effective way to meet the timber retardant requirements of particularly if your need is for the treatment of external door and window frames, floor bearers, decks and pergolas and other timbers.
As unfolded, there are various types of coatings for the this retardant, and therefore is upon an individual to chose. During the selection, it is recommended that one gets to understand the functions of theses coverings and the mechanism behind its use. This ensures good and effective decision making that will yield satisfactory
