Q: Which industry does refractory belong to? Does it belong to construction industry?: I am engaged in construction. Refractory material does not necessarily belong to construction industry. Fire resistance is only a part of material?performance. Indeed, there are many places requiring refractory accorded with fire resistant level.

Q: Is there any difference between insulating bricks and refractory bricks? Are there any professional refractories factories that are reliable in the quality and quality of these irritated materials?: Physical and chemical property indexes of high strength and high alumina refractory bricksProject indexPLG-1.0 PLG-0.8 PLG-0.5 PLG-0.4AI2O3% 56545250Fe2O3%, 2, 2, 1.5, 1.5Bulk density g/cm3 1, 0.8, 0.5, 0.4Normal temperature compressive strength MPa shall be no less than 7531.5A change of a burn line of not greater than 2%The temperature is 1400140012501250 centigradeThe coefficient of thermal conductivity, W/m.k average temperature (350 + 5) is not greater than 0.45, 0.35, 0.25, 0.20

Q: Can anyone say something about the curtain wall fire-proof material key sealing point?: Keypoints; 1, curtain wall design must consider the safety requirements, one of which is fire protection design. 2, Generally, fire protection planning between curtain walls should use the method of setting fireproof isolation layer. 3, Two layers of fireproof isolation layer whose thickness should not be less than 100mm respectively on the top edge and lower edge of the material parts of the house. 4, the fireproof isolation layer commonly uses 1.5mm thick galvanized steel sheet as supporting plate, using for shelving fireproof sheet. The 100mm thick cavity between the layers is filled with mineral wool non-combustible materials tightly covered with tinfoil on the surfaces. 5, protective isolation layer should try to reconcile curtain wall beam level and finish floor level, so as to fill non-combustible material and to avoid that a piece of glass acrosses two fire?compartments. 6, the beam should be inside 100mm thick fireproof isolation layer to protect the beam and the upper curtain wall plate. 7, when there are open fire function areas like large-scale hotel or restaurant kitchen inside the curtain walls, curtain wall glass in these parts should consider using cesium potassium fireproof glass to improve the fireproof rating in the region. 8, Fireproof setting in the around areas of curtain wall can use the same method of the above fireproof setting between layers. The joint parts of fireproof isolaton layer and main part as well as curtain wall should use fireproof sealant to seal.

Q: Who knows what kind of material the fire-proof plate use, and is it good?: It is the decorative board made by adopting silicious material or calcareous material as the main raw material, and blending them with certain proportion of fibrous material, lightweight?aggregate, adhesive and chemical?additive before steam pressing. It is a kind of new material and more and more frequently used currently not only for it is fireproof. Construction of the fire-proof plate has higher requirements on the adhesive, and the price of the fire-proof plate with better quality is more expensive than that of the decoration panel. The thickness of the fire-proof plate is generally 0.8mm, 1mm, and 1.2mm. So it is the best material for making cupboards.

Q: What are the models of bauxite with high alumina?: China Ferrous Metal Industry Corporation released the industry standard of bauxite (YS / T78-94) in 1994. According to this standard, bauxite can be divided to sedimentary diaspore, stacked type diaspore and lateritic gibbsite. According to the chemical composition, it can be divided into nine trade marks as LK12-70, LK8-65, LK5- 60, LK3-53, LK15-60, LK11-55, LK8-50, LK7-50 and LK3-40. In addition to the provisions of chemical composition of bauxite, the standard also requires that the water of sedimentary diaspore shall not exceed 7% and water of stacked type diaspore and lateritic gibbsite shall not exceed 8%. Moreover, particle size of bauxite should be not greater than 150mm. Bauxite shall not be mixed with clay, limestone and other debris.

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: Does the refractory material used in steelmaking all refer to refractory brick?: It includes not only refractory brick but also unshaped refractory; while the foaming?agent, ladle filler sand and deoxidizer are not refractory materials but ferrous metallurgy auxiliary materials.

Q: Which are roofing fireproofing material?: (1) Foamed concrete is a kind of fire-proof thermal inuslation matertial featured by good fire resistance and thermal insulation. Besides, it is also characterized by excellent sound proofing, penetration resistance, easy construction, safety and environmental protection without toxin and pollution. (2) Foam glass is featured by light weight, small heat conductivity coefficient and water absorbption, non-inflammability, fire resistance, high strength, no moulding, corrosion resistance, non-toxin and stable physical and chemical properties and thus widely used petroleum, chemical engineering and underground construction. It is also featured by thermal insualtion, heat/cold preservation and sound absorbption and thus can be used for thermal insulation of external wall and roof of civil builduing. Foam glass is featured by stable chemical property, easy to be processed and not easy to deforme, and durable. (3) With slag, basalt and other natural ore as the main raw material, rock wool, mineral wool and its products are made by high temperature melting into fiber, and then processing with binder. It has low thermal conductivity, fire resistance, easy construction and good effects of energy saving and thus is highly cost-effective. (4) With phenolic foam material as main material, phenolic resin plate is made by foaming thermoset phenolic resin. It is featured by light weight, fire resistance, no burning in the air, no smoking, non-toxin, no dropping and non-embrittlement and thus is an ideal thermal insulation material used in HAVC projects. Due to its high obturator formamen rate, low heat conductivity coefficient, good thermal insulation, water resistance and water vapor permeability, phenolic foam is an ideal thermal insulation material.

Q: What's meaning of CN of fire-resistant material?: The commonly used preparation methodsinclude shock compression, high-pressure pyrolysis, ion implantation, reactive sputtering, plasma chemical vapor deposition, electrochemicaldeposition, ion beam sputtering, , low-energy ion radiation, pulsed arc discharge,pulsed laser inducing, etc. But the compounding result of superhard materialis not ideal due to deposition of amorphous CN film, nanometer level sizedC3N4 crystalline grain set in the amorphous film and few large graincrystal.
