What material is made of fire retardant?
Of course, there are some cheap, of course, there is not so high standardsAs for 4000 degrees of temperature, at least for the time being, it has not reached such high temperatures for protective clothing.
But the protective clothing is still unable to withstand 4000 degrees, the material said above, in the 1400 degree is barely kept stable in nature, to 1600 degrees basically started structural changes, will soon lose his insulation properties.
However, if the equipment, such as some equipment need to reach 4000 degrees occasions, they can achieve isolation, mainly is the vacuum isolation, and then through the outside cooling equipment and other insulation materials to achieve.
Usually asbestos, some of which are made of zirconium and zirconium and silicon mixtures, and some are made directly from natural objects.Usually it can withstand 1400 degrees over 30 seconds, while no obvious internal temperature changes, more than 5 minutes, the internal temperature is not more than 5 degrees.
