BAIJIAN - Third party testing organization
The testing range of refractory materials is divided according to the level of fire resistance: ordinary refractory materials: 1580 ℃~1770 ℃, gaoji refractory materials: 1770 ℃~2000 ℃, special grade refractory materials:> Refractory materials at 2000 ℃ can be divided into fired products, unburned products, and amorphous refractory materials according to their chemical properties. Acidic refractory materials, neutral refractory materials, and alkaline refractory materials are classified according to their chemical mineral composition: siliceous (silicon oxide), aluminum silicate, corundum, magnesium, magnesium calcium, aluminum magnesium, magnesium silicon, carbon composite refractory materials, and zirconium refractory materials, Special refractory materials - Classification of amorphous refractory materials (based on the method of use): castable, spray coating, ramming material, plastic, pressing material, projection material, coating material, dry vibrating material, self flowing castable material, refractory slurry testing items: flame retardancy, ignitability, smoke toxicity, smoke density, heat release and smoke, fire resistance, combustion performance, combustion heat value, fire resistance, high temperature resistance, heat release rate Horizontal combustion, vertical combustion, monomer combustion, fire rating testing, volume density, apparent porosity, true porosity, fire resistance, load softening temperature, thermal expansion coefficient, heating temperature change, room temperature bending resistance, high temperature bending resistance, silicon oxide, alumina, lanthanum oxide, beryllium oxide, calcium oxide, zirconia, etc
Function of testing report:
