Q:What's the organzational structure of refractory material?
Although hacing same chemical composition refractory material products also is mineral organizer. There are differences in the type of mineral phase, high refractoriness under load, quantity and crystalline state. The organizing minerals and microstructure are reflected by folding strength, high temperature pit definite density torsional strength, high-temperature torsional strength and product property. But, for example, wear or crack may cause damage. The performance index can reflect the internal structure of refractory: the nature of the thermal performance---linear expansion coeffcient. And the mineral composition of refractory material depends on the chemical composition and process conditions, the heat capacity and temperature conductivity. If the processing conditions are different, the influence of chemical action, and thermal conductivity: represents the nature of the mechanical properties - normal temperature, high temperature compression strength, high temperature creep performance and elastic modulus. Chemical compositions are the basic characteristics of refractory, representing the nature of the density---porosity, corrosion occurred refractory materials in high temperature use As a result, the composition and quantity directly determines the performance of refractory, true density: representing the forming of high temperature performance --- refractoriness, high temperature volume stability, so you can't analyze the effect on the product performance just from chemical composition. The performance of various refractory materials are different. It must be emphasized that macroscopic organization structure of refractory material is also an important factor that affects performance; reflecting complexity of penetration---air permeability, thermal shock resistance and slag resistance. The main component is the foundation of refractory characteristics.
Q:I wanna ask that magnesium oxide is refractory?
Yes, Magnesia belongs to ionic crystals, the oin of magnesium has two charge, oxygen and magnesium ions are relatively small radius, these two factors make a lot of magnesium oxide lattice energy, high melting point is up to 2800 degrees Celsius. Because the magnesium oxide is stable and not react with water, it is widely used as a refractory material.
Q:Does the aluminum silicate thermal insulation material fireproof?
it can be fireproof and has a strong fireproof performance.
Q:Does hardware construction materials contain refractory?
refractory includes one kind of building materials. It is a special material and not commonly used.
Q:Does anyone know what is the use of waste refractory materials?
Waste refractory materials can be 1, Recycled to do the aggregate and powder of castable , or make bricks. 2, can be reused after smash.3, Metal silicon is an anti oxidant in refractory material, mainly functioning as he oxidation resistance, at the same time improve its toughness.
Q:What materials are needed to make the amorphous refractory bricks?
Amorphous refractory bricks have good quality, good reputation, complete in specifications,high refractoriness, strong resistance to slag, and long service life. It’s worthwhile.
Q:What kind of materials can be tested their electrical resistivity in the current refractory industry?
Graphite, Magnesium Oxide, and alumina are all feasible.
Q:Who can tell me about the foundry refractory materials?
The classification of refractories commonly used in casting and smelting: refractory bricks: siliceous bricks, high alumina bricks, corundum bricks, magnesia bricks, magnesia-alumina bricks, magnesia-carbon bricks,etc. shapeless refractory materials: ramming mass, castable refractory, refractory cement, silica sand, magnesite, etc.
Q:what's the seal of fireproofing material?
Organic fire-proof caulking is made by taking organic synthetic resin as bond and compressing the components together after adding fireproofing agent, filler. The putty won't solidify after a long time usage and has good plasticity, can be sealed arbitrarily. This kind of putty is mainly applied in opening's fireproofing and sealing project of construction pipe and electric wire and cable, and it's used with ATD-AB and fire retardant bag together. ATD-AB is a kind of gray powder material, after mixed with water, it can be used for the opening sealing of electric wire and cable or fire resisting wall of wire tunnel. The fire proof blockage is non-toxic, and no smell, has good water resistance and oil resistance with simple construction methods. It's oxygen index is 100 and it belongs to incombustible material. it's refractory time can reach 3 hours, or above or below. as for some projects for perpetual usage, WXY-II will save the project fee and make the project solid. A kind of fireproofing material that can automatically expand and foam and sealed by opening after injecting the foam into opening. Sealing strip is a product or flexibility coiled material mede by fireproofing material with certain geometry shape. Sealing gum is a kind of liquid fireproofing material that has a function of fireproofing and sealing. Fire retardant bag is soft and windable tape-shaped product made by fireproofing material, it is winded on the external surface of plastic pipe and fixed with steel belt or other proper methods, it's the expansion, squeezing and softening pipe after contacting with fire, opening left by burning or soften of seal plastic pipe. Fire retardant ring
Q:How to classify fire resistance rating of brick-concrete structure?
In order to ensure the safety of the building, the fire protection measures must be taken to make it have a certain degree of fire resistance, even if there is a fire, it will not cause too much damage. According to the national conditions of our country, and in the light of other countries standards, < high-rise civil building fire protection design specification > defines fireproof rank of high-rise civil buildings into level one and two; < code for fire protection design of buildings > divides the rank into level one, two, three, four, level one is the highest level, level four is the lowest. Besides that the minimum fire resistance of the building component is specified, buildings of fire resistance rating also specified requirements for combustion performance. Because the component with the same fire resistance limit is different, it is different in the fire.According to our country national standard < building design fire protection code >, the fire resistance rating of the building is divided into four levels. The fire resistance of a building is determined by the combustion performance and fire resistance of building components (such as beams, columns, floors, walls, etc.). Generally speaking, the fire resistance building of level one is a mixed structure of reinforced concrete structure or a mixture of brick wall and steel concrete structure; the fire resistance building of level two is a mixed structure of steel truss structure, reinforced concrete column and brick wall; the fire resistance building of level three is brick-wood structure made of wood roof and brick wall; the fire resistance building of level four is combustible structure which is composed of wood roof and non-combustible wall.
