Fireproof Materials and Products GB 12441-2005 "Decorative Fireproof Coatings"

Material Analysis 百检检测 2023-12-11

A type of inorganic non-metallic material with a fire resistance of not less than 1580 ℃. Fire resistance refers to the Celsius temperature at which a conical sample of refractory material can resist high temperature without softening and melting under no load. But defining refractory materials solely based on their fire resistance is no longer sufficient、 and 1580 ℃ is not absolute. The current definition is that materials with physical and chemical properties that allow them to be used in high-temperature environments are called refractory materials. Refractory materials are widely used in industries such as metallurgy、 chemical engineering、 petroleum、 mechanical manufacturing、 silicates、 and power、 with the largest usage in the metallurgical industry、 accounting for 50% to 60% of the total production

Performance

The physical properties of refractory materials include structural performance、 thermal performance、 mechanical performance、 usage performance、 and operational performance.

The structural properties of refractory materials include porosity、 bulk density、 water absorption、 permeability、 and pore size distribution The thermal properties of refractory materials include thermal conductivity、 coefficient of thermal expansion、 specific heat、 heat capacity、 thermal conductivity、 thermal emissivity、 etc The mechanical properties of refractory materials include compressive strength、 tensile strength、 flexural strength、 torsional strength、 shear strength、 impact strength、 wear resistance、 creep resistance、 bonding strength、 elastic modulus、 etc
