Q:What kind of material is good for cabinet fireproof board
What kind of material is good for cabinet fireproof board What are the advantages and disadvantages of using it? How much is the price? A about how much does one piece cost?
Q:what's the requirements of refractory for forge furnace?
. . . . . . . .
Q:The principle of choosing fire-resistant material in Thermal Energy and Power Engineering equipment.
Different thermal technology equipment has different operation condition and select different refractory material. We should take economical and practical as principle.
Q:How about the prospect of refractory material?
Due to the rise of raw material, the prospect is not good with inflation, lower prices and decreased profits. The product requirements have been enhanced and there is vicious competition. Therefore, it is really bad.
Q:What is the quote of fireproof and soundproof materials used in KTV?
acoustic material, aluminum foil glass wool, sound-deadening material, glass wool, cinema / KTV dedicated glass wool: The classification of glass fiber products: The category of glass wool felts: The level of insulation cotton: A-level brands: New applications: The origin of GB/T13350-2008: The coefficient of thermal conductivity(room temperature): 0.035 bending at low temperature≤: 0.02 elongation at break: ≤80kPa flexure strength: ≤120kpa Compressive strength: ≤150kpa application temperature: 700 Core material: The shape of glass wool: Fibrous shape: Coil Specifications: Complete quote is 23 Yuan per cubic meter. glass wool board, KTV sound insulation core material: The shape of glass wool: The level of rectangular glass wool: A-level non-combustible brands: Kunnai material: The origin of glass fiber: Guangzhou, Shijiazhuang, Wuhan, the quote there is 8.8 Yuan per cubic meter.
Q:What are fireproofing materials?
Plants often use the fireproof sealing material with steel structures without much modification. All the panels that meet the first-order fire protection requirements can be fireproofing materials. Like gypsum boards, aluminum sheets and so on. . Coatings are usually those with fine powder, high density and good sealing. Hardeners mainly depends on specific requirements. .
Q:How do refractory materials apply into pyrophyllite?
Generally speaking, shaped refractory materials require of some powdery materials like spray grouts and iron trough in addition to pyrophyllite brick made of a mixture of pyrophyllite aggregate and powers.
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:which kind of refractory is used in golden smelting furnace? How about his using temperature
generally the price of the quartz sand refractory material is higher and the temperature can meet the requirement of 2000 degree.
Q:What are the construction fire-proof materials?
1. fire retardant coating 2. fireproof panel 3. fire proof and sealing material 4. flame resisting decorative materials 5. Green fire prevention materials
