2000 ℃ expansion high temperature resistant thermal insulation coating

Product description

This product is made of a special solution that can be solidified by the second solid phase Film-forming substance ， filler from nanometer Grade alumina, zirconia, carbon fiber, hollow carbon nanotube, expanded graphite, silicon carbide, etc. are formed under high temperature and pressure. After being heated, the coating expands, its volume can reach more than five times of the original coating, its temperature tolerance can reach 2000 ℃, and the thermal conductivity of the expanded coating is 0.022W/m.k. coating It can be painted on any organic and inorganic material with good adhesion, high hardness, good abrasion resistance and impact resistance, and can withstand open fire for a long time. The fire rating can reach Grade A.

Expansion type high temperature resistant insulation Thermal insulation coating After the coating is completely cured, it is better to be heated at two hundred When the temperature is higher than ℃, the volume expands. With the increase of temperature, the coating expands in a parabolic manner until the temperature rises to one thousand When the expansion process ends at ℃, the coating is completely formed, and the coating thickness is more than five times of the initial coating. After expansion, the coating forms numerous separate vacuum layers, which * * * prevents heat conduction and has more obvious heat insulation effect.

High temperature kiln and furnace; High temperature mold, pipeline, electric furnace, induction furnace, rotary kiln, etc. Use in one thousand On high temperature equipment above ℃, to ensure the full expansion of the coating and achieve better thermal insulation effect.
