Who knows what are the ability of 1300 degrees above the high temperature, insulation materials?
Where the ablative material is also high temperature resistant material. For example, in the 300 ~ 600 ℃, in the air to maintain its mechanical strength, chemical resistance and so on.
Heat-resistant polymers can be used as high temperature resistant film insulation materials, high temperature resistant fibers, high temperature resistant coatings, high temperature adhesives. In accordance with the high temperature of the time, but also sub-instant high temperature materials and high temperature materials for a long time. The former in 1000 ~ 10000 ℃ can withstand a few seconds to a few minutes.
Such as tungsten, molybdenum, tantalum, niobium, vanadium, chromium, titanium, zirconium and other refractory metals and rare earth metal borides, carbides, nitrides, silicides, phosphides and sulfides; the latter such as boron carbide, Silicon carbide, boron nitride, silicon nitride, boron phosphide, silicon phosphide and the like. The latter has a very important use, can be used as high temperature refractory materials (such as abrasive, mold, nozzle, high temperature thermocouple casing), heat-resistant materials (such as rocket structure components, nuclear engineering materials, electric components), electrical materials Such as high temperature thermocouple, ignition electrode), in addition to chemical resistance materials and hard materials.
High temperature resistant materials include refractory and heat resistant materials, inorganic compounds, and polymer materials. Refractory material usually refers to the resistance of 1580 ℃ above the temperature of inorganic materials. They are built kilns, combustion chambers and other building materials that require high temperatures. General use of quartz sand, clay, magnesite, dolomite as raw materials and made, such as refractory cement, magnesia and so on. Broadly speaking, inorganic refractory, heat-resistant materials refers to the high hardness of these compounds, good brittleness, good chemical resistance, and the melting point of 1500 or more. Mainly divided into metal and non-metallic compounds and non-metallic compounds.
