Q:do the used refractory bricks pollute the environment?
the main pollution of refractory brick is coal gas pollution in the process of burning , it can be recycled to produce aggregate, waste brick has no pollution.
Q:Are buildings allowed to use red bricks?
Is the red brick with clay, shale, coal gangue as raw materials, crushing, mixing kneading with artificial or mechanical pressing, sintering and building bricks after drying at 900 centigrade temperature by oxidizing flame firing, invented by the babylonians.
Q:What materials make of clay insulating fireclay brick?
Clay insulation bricks are general according to the different origins of raw materials, not the same
Q:What are the main constituents in non clay brick sintering?
Unfired bricks are bricks used to build walls relative to sintered bricks.
Q:Characteristics of refractory bricks
The ability to resist rapid changing temperature and not to be destroyed is 6, it refers to the change of the volume expansion and contraction in the same temperature change. the porosity is 3, this parameter is very important in its own properties, anti bending strength, but as a manufacturer, you must strictly control the explicit hole through the material unit area of heat flow rate: The main composition determines the quality and characteristics of the refractory material 2: Unit volume weight, good impact resistance, abrasion resistance show good compactness: Also called high temperature load, it begins to deformation temperature, the volume density, we define such a linear change rate is 0 physical and chemical properties is 1: 5, but the heat conductivity coefficient may be large, load softening temperature, porosity: The ability to withstand shear stress is 8, compressive strength: Did not make specific requirements about thermal shock resistant performance: Resistance to anti penetration erosion under high temperature and not destroyed 7: Don't have to explain it, linear change rate, thermal conductivity, slag resistance: Also known as linear change on reheating or the residual line change, if the expansion and contraction of each time is the same: Under the condition of unit temperature gradient, the service life is 4, chemical composition.
Q:The foundation is made of Mu10, which is new clay brick and M7.5 cement mortar. What does it mean?
MU10 is the strength of bricks, and M7.5 is the strength of cement mortar.
Q:The harm of wet bricks used in refractory bricks
Increase the natural protection time, increase the baking time, or water can not discharge, this will cause swelling deformation of furnace wall.
Q:can the red brick be used as refractory brick?
1200---1750 of the refractory bricks, below 1000 degrees of red brick brick is ok.
Q:What is the biggest difference between refractory bricks and clay refractory bricks?
Q:is it correct that the higher the refractoriness is, the better refractory bricks are?
Does not necessarily, it has a great relationship with the compression and bending and corrosion resistance.
