- Q: Who knows what is the standard of insulation material whose fire proof is level A?
- Non combustible materials of level A: WW inorganic active wall thermal insulation material, Cement foaming thermal insulation board, Glazed hollow bead insulation mortar, rock wool board, Glass wool board, Foam ceramic.Non combustible materials of level A, endowed with low density, low thermal conductivity, higher bearing capacity, convenient construction , economy and durability, are widely used in heat pipe, heat equipment, other industrial pipeline equipment , thermal insulating materials on industrial buildings, and used as heat preservation, thermal insulation, sound absorption materials of industrial and civic buildings.Non combustible materials of level A are used more for refractory protection coating material of steel structure because of its good thermal stability.
- Q: How many hours of the fire endurance time of the rock wool laminboard?
- This is depending on the fire rating, about two hours and the better one, 5 hours.
- 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: Would you like to know if there are any enterprises in Mianyang that need fire-resistant materials?
- Many enterprises need refractory materials. You can go to Mianyang large private enterprises to askSupermarkets, stations, hotels are required
- Q: What's the difference of fire-resistant material's density, specific gravity and bulk specific gravity?
- glass
- Q: What's the heat conductivity coefficient, specific heat capacity and density of the refractory material of magnesite-chrome brick and magnesia-alumina brick respectively?
- It is suggested that you find some samples of well-known manufacturers, such as Ogilvy and Mather Group, and that will be more correct.
- Q: Can polystyrene foam color steel plate be used as decorative fireproofing material ?
- Polystyrene foam plastic can not be used as fireproofing material; polystyrene foam plastic is made up of polystyrene resin as main component, foaming?agent and other additives. It is a buffer material which is most widely used[1]. It is closed hole structure, so it has low water-absorbing quality and excellent water resistance; low density, about 0.015 ~0.03; good mechanical strength, excellent buffer?performance; good machinability, easy to be moulded; good dyeing property, thermal adaptability and anti-radiation; high dimensional accuracy, uniform structure. Therefore, it has a large share in external wall thermal insulation. But it will emit polluted styrene gas when burning. It is a kind of class B material in construction.
- Q: What are the materials used in refractory material processing?
- Refractory materials generally refer to inorganic non-metallic materials with a refractoriness of more than 1580 degrees. It includes natural ore and a variety of products made by a certain process according to certain requirements. It has certain high temperature mechanical properties and good volume stability. It is the necessary material for all kinds of high temperature equipment. Ordinary refractories are often used brick, semisilica brick, clay brick, high alumina brick, magnesia brick etc..
- Q: Are there any differences between insulation and refractory materials ?
- Refractory materials can resist more than 1200 degrees, some of which are not insulation materials, such as firebricks, which can directly contact with heat source, has little insulation effect. Ceramic fiber, high silica, etc. are all refractory materials which can insulate. Insulation materials with poor performance usually is lower than 800 degrees, which have large thermal resistance, and low thermal conductivity, high porosity. Thus they reduce the thermal loss. To put it simply, insulation materials store most of the heat and only let a small part of heat lose through the air, thus the heat has been isolated. Glass fiber, rock wool, flexible material for thermal insulation, etc.
- Q: Where is the development of refractory industry?
- The rapid development of continuous casting technology of its related @ China @4 honing refractories develop and increase in variety and quality, continuous development of refractories for the continuous casting billet continuous casting production and quality have a significant impact. Especially, the completion and operation of Baosteel have greatly promoted the technological progress of refractory materials in China, and the refractory materials for continuous casting have made great progress both in variety and in quality.
