- Q: What's the maximum temperature that the high-temperature resistant refractory ceramic fiber cotton can endure?
- Nichrome wire, stainless steel wire and glass fiber are reinforced. Ceramic fiber coating cloth and slag cloth, sintering ceramic fiber cloth and ceramic fiber fumigation cloth) Characteristics of the ceramic fiber cloth: high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment; Applications of ceramic fiber cloth: It can be applied to the thermal insulation of all kinds of furnaces, high-temperature pipelines and vessels; furnace doors, valves, flange seal, fire doors, fire resisting shutters and high-temperature furnace door curtains; engine and instrument insulation, clad material of fireproof cables, and high-temperature resistant and fire-proof materials; thermal insulation cloth for coverage, high-temperature expansion gap padding, and inner linings of the flue; high temperature resistant labor safety products, fireproof suits, high-temperature filtration and sound absorption, replacement of asbestos, etc.
- Q: What's the difference between refractory metal raceway and fireproof raceway?
- Fire protection slot won't cause fire accident under the temperature of no more than 200℃. While the refractory cable tray is made with refractory materials and can withstand high temperature of 800℃ with no fire accident happening. The test standard depends on the maximum temperature it can endure. Hope it's helpful for you!
- Q: How long is the duration of fire resistance that fireproof window of level B can endure?
- Level B refers to the fire resistance rating and different hours in fireproofing of the fireproof window. Fireproof window of level A can endure fire for 1.5 hours while level B, 1.2 hours
- 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: Who knows which chrome refractories produced by the Henan refractory plant can be used for continuous casting?
- Field casting experiments are needed to verify,
- Q: What is the appropiate thickness if fire resistant time for ultra thin steel structure coating is 2.5 hours?
- A level fire resistant steel structure building steel column cannot be constructed with super thin steel structure fire retardant coating, because the ultra thin steel structure fire retardant limit is less than 3 hours. Thin fire retardant coating for steel structure is water borne fireproof coatings painted on the surface of steel structure. It will form carbonized fireproof heat insulation protective layer to insulate oxygen and delay the speed of heating steel structure when it catches on fire, avioding the rapid temperature rise of steel structure and increasing its fire resistant limit. Fire resistance performance: The 2mm coating ≥ 60min, 3mm 100min.
- Q: Does anyone know about the fire resistance period of thin fireproof coatings?
- The thin fireproof coatings will be expanded when exposing to open fire, and produce the inert gas to extinguish fire, but they will do harm to people, and the coatings are not stable, and the weather resistance and service life of which are short. According to the state regulations, the thin fireproof coatings have the highest fire resistance of only 2.5 hours, while the thick steelwork fireproof coatings have a fire resistance of 3.0 hours or more.
- Q: What are the new types of refractories? What are the characteristics? Their applications and developments?
- A new type of refractory materials are: A12O3-TiO2-SiO2 refractories, MgO-A12O3-TiO2 refractories, MgO-CaO-TiO2 refractories, MgO-SiC-C refractories, nanotechnology MgO-C brick, MgO-AL2O3-AIN refractories, MgO-La2O3 refractories etc..
- Q: What are the commonly used admixture for alumina-magnesia refractory? What are the impacts on its performance?
- 2, form Mg-SiO2 coagulation and combination, CA cement bond? Bricks can generally be made by combing with phenolic resin, castable use 1, combined with silicon powder; 3, can also combined with brine MgCl is binding agent
- Q: What is the fireproofing requirements of external wall thermal insulation materials?
- External wall thermal insulation materials fire rating regulations, 1, the height of a building is greater than or equal to 100m , the combustion performance of insulation materials should be level A; 2, the height of a building is greater than or equal to 60m but less than 100m, the combustion performance of insulation materials should not be less than the level B2. When using level B2 thermal insulation material, every layer should set horizontal fire barrier zone 3,The height of building is be equal or greater than 24m but less than 60m, the combustion performance of thermal insulation material should not be less than the level B2. When using level B2 insulation material, each two-layer should set fire barrier zone ; 4, the height of building is less than 24m, the combustion performance of insulation materials should not be less than the level B2. Besides, when using level B2 thermal insulation material, each three-layer should set a horizontal fire barrier zone.
