The fire may be the best thief in this world

The fire may be the best thief in this world. That conclusion is exaggerated, because it can never be caught and punished destroys valuable links, cash and securities. The best thing anyone can do to save important documents is to hide them from this thief. Here's an article that tells of the materials used to create these special places to hide. Polymers are a great gift for the man in this sense.
 
Now early in the reign of the Egyptians, the man is trying to make composites that can withstand the fire. Ancient composite with a combination of chalk and clay, plaster and hair, alum and vinegar, chalk and ammonium chloride, etc. In fact, the concrete is fire resistant to some degree and yet cheap, which is used a lot:fire alarm systems,home alarms,house alarm,fire alarm system.
 
The actual marketing and mass production of fire alarm systems,home alarms,house alarm,fire alarm system these materials has begun to see the aftermath of the Second World War. a fire retardant polyester fabric and coated with paraffin compounds and antimony oxide were used. In general, fire-resistant synthetic polymers is much more difficult than usual to cover polymers with fire resistant additives. But polymers are inherently fire resistant dedicated loads better. The use of polar monomers in the ability of high-hydrogen bond and the presence of many groups to increase the fire resistivity of an inorganic polymer.
 
Simple linear polymer chain cyclic aromatic compounds are rigid and costly, but is one among the fire-resistant materials higher. Polybenzoxazoles, Polybenzimidazole, polyamide polymers are few who fall into this category. Some polymers with heterocyclic aromatic monomers linkages that look like scales and are more serious. All the polymers that many groups tend to be fire resistant inorganic. Well, the man is never satisfied with what he has accomplished and is always looking for something better than existing ones. This means we can expect more material to come save us.
