A burned out 100-story building

    Recently, Changsha Telecom building burst into fire, the scene of the smoke billowing. Fortunately, after the arrival of firefighters, the fire was quickly controlled and no casualties were found. According to people at the scene, it took less than 10 minutes from the fire to the entire building burning into a dark ruin.

So the question is, how did a 218-meter tall building burn down in just a few minutes?

    In addition to the "chimney effect" formed when high-rise buildings burn, the choice of building materials is also related to fire safety. According to media reports, the flammability of building external wall insulation materials, or the main reason for such heavy losses in the fire.

Second, "water and fire merciless" loss

    As the old saying goes, "fire and water have no mercy," and fires have become a catastrophic problem for countries around the world, according to the United Nations' World Fire Statistics Center. On average, every 12 years, the losses caused by fires in China will double, and the direct property losses caused by fires reach billions of yuan each year.

    In recent years, the average annual fire in our country about 40,000, the death and injury of about 4000-6000 people, especially caused dozens of people, hundreds of people died of extremely vicious fire occurred, to the country and the people's lives and property caused huge losses.

Third, building materials determine the speed of fire spread

Before the Ministry of Public Security issued Document No. 65 in 2011, thermal insulation materials for civil buildings were mostly flammable and combustible materials. After the Ministry of Housing and Urban-Rural Development issued the national standard "Code for Fire Protection in Building Design" in 2014, building insulation and exterior wall decoration were standardized. However, for buildings that have been built before 2014, the fire resistance of external wall insulation materials cannot be guaranteed.

However, this does not mean that old buildings must have a fire crisis, for "old" buildings, coating the exterior wall of the building is a convenient and cost-effective choice.

Fourth, choose a good flame retardant coating to avoid major losses

Flame retardant coatings are difficult to hydrophobic, and the non-flame retardant of hydrophobic coatings has always been a difficult problem for hydrophobic coatings to overcome. The researchers of Titanran technology successfully solved this technical difficulty by controlling the amount of P element and the operation method, and the flame retardant effect of the coating developed by Titanran has reached the highest level (HB) of the National Quality Inspection Center, and extended the heat reflection thermal insulation coating series products:

1, new reflection heat insulation energy-saving flame retardant multi-functional polymer nano coating: heat reflection, heat insulation, flame retardant, hydrophobic as one of the new functional nano coating. It is composed of inorganic non-metallic new materials, phosphorus-containing flame retardants and fluorosilicone resins. The closely packed inorganic nonmetallic materials have the characteristics of low thermal conductivity and high reflectivity. The ultra-high sunlight reflection ratio of 0.91 can be used for building heat insulation and cooling as well as fire retardant.

2, the new thin layer of high temperature flame retardant insulation multi-functional material: set heat insulation and insulation, waterproof and mildew, fire prevention and corrosion prevention in one of the new efficient energy-saving thin layer material, can face the open flame for a long time, and effectively reduce the burning speed of combustible materials, strong temperature resistance and flame retardant, in the film formed after the low radiation heat transfer structure overall has excellent heat insulation and insulation effect.
