Detailed Product Description: | Refractories (Refractory material) the true density is the true density refractories (Refractory material) in the solid mass to its true volume (volume of solid portion) ratio. True specific gravity is the ratio of the true mass of the unit volume of the material mass and 4 ℃ unit volume of water. Both can be considered the same in value. The international community has a true specific gravity of this concept is no longer used, but in Japan refractories (Refractory material) Technology Association of editing and publishing the "refractories (Refractory material) Handbook," a book refractories manufacturers are still using real GDP. Refractories (Refractory material) in the true density is a measure of quartz silica brick extent of conversion of important technical indicators. Different true density of SiO2 composition of the various minerals, the true density of the minimum phosphorus cristobalite, cristobalite, followed by quartz maximum. Phase transition in multiphase material, the chemical composition of a certain time, according to the data to determine the true density of the material phase composition. For the true density refractory sales of refractory products and refractory materials, according to the national standard GB / T5071-1997 (identical with ISO5018: 1983) were measured. Aggregate is used to configure acid refractory castable mainly silica, cast stone, alabaster, andesite, diabase. Acid resistance of several commonly used raw material (how much refractory as measured by weight,%) as: cast stone 98%, greater than 97% silica, 92% -96% clay clinker, andesite greater than 94%. Depending on the selection of the raw material conditions. But the use of silica, quartz polycrystalline change must be taken at the time of heating, the change process will produce a volume change (expansion), so it is best to replace part Fischer silica brick raw material to make the aggregate, the preparation of this castable material powder The main use of silica powder, cast stone, porcelain powder, high siliceous clay clinker powder, casting powder which is used more acid powder. General Ingredients acid refractory castable composition: Acid refractory aggregate: 60% -70% 30% -40% powder, plus a density of sodium silicate solution 1.38-1.42g / cm3 of 13-16%, with fluorosilicone When sodium as the hardening accelerator in an amount of 10-12% water glass solution quality.
