- Q: What are the materials of insulation firebricks?
- The furnaces of firebricks are generally divided into two types, namely, unshaped refractory materials and shaped refractory materials. Unshaped refractory materials, also called castables, is a mix of powdery particles of many aggregates and one or multiple adhesives. They must be stirred well with one or multiple liquids when in use, which has a strong liquidity. Unshaped refractory materials generally refers to firebricks. They have standard rules about their shapes and can also be processed temporarily as needed.
- Q: I wanna ask about the building insulation materials fire rating?
- Hello, I am happy to answer your questions about the classification of building insulation materials fire rating: 1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3 combustion performance is level B2 insulation material: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. I hope I can help you
- Q: Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?
- Strictly speaking, as long as there are solid wood packaging, you need to do fumigation inspection, proved not necessarily used, there are IPPC chapters on it.
- Q: what is the original materials of fireproof coating?
- Main raw material includes high-temperature aluminum surface, expanded vermiculite,closed cell perlite, high mark number cement, Fireproof paint itself is flame-retardant or non-combustible, protecting the substrate from direct contact with the air,delaying the time for catching fire and reducing the burning speed. For example, indoor thick fire retardant coating for steel structure.
- Q: Selection of refractory materials?
- Inorganic non-metallic material with a refractoriness of more than 1580 degrees. Refractoriness refers to the temperature of a sample of a refractory cone, which is resistant to high temperature without softening, and does not soften and melt down. Refractory materials are associated with high temperature technology, which originated roughly from the middle of the bronze age. In the Eastern Han Dynasty has made China kiln firing porcelain material and with fireclay refractory sagger. In the early twentieth Century, refractory materials were developed towards high purity, high density and ultra high temperature products. At the same time, unshaped refractory materials and refractory fibers without firing and energy consumption were developed. With the development of modern technology, atomic energy, space technology, new energy technology, refractory material having high temperature resistance and corrosion resistance, thermal shock resistance, erosion resistance and other comprehensive excellent performance has been applied.
- Q: Which kind of furnace hearth refractory is better?
- Coal is acidic medium, so the matched material should be acidic refractories oriented, like silica?bricks. For example, the coking coke oven and carbon furnace made of carbon are in reducing atmosphere, so they use silica bricks which have low price and good high-temperature indicators. If the part has special requirements, you can then consider other refractory on request.
- Q: How long is the fire-resistant time of fireproof wooden door?
- National standards define the fireproof door as class A, class B, class C, among which fire-resistant time of class A fireproof door should not be less than 1.5 hours, class B should not be less than 1 hour and Class C should not be less than 0.5 hours.
- Q: what is the specs of thermal insulation refractory slab ?
- thermal insulation refractory slab features wear proof, heat resistance, impact resistance, acid or alkali resistance, smoke resiatnce, fire proofing,fungi proofing, mould proof,anti-static. fireproof panel is generally used for countertops, tabletops, walls, cabinets, office furniture, wall hung cupboard. Common Specifications: 2135mm × 915mm, 2440mm × 915mm, 2440mm × 1220mm, thickness 0.6-1.2mm.
- Q: How many external wall thermal insulation fireproof material are there
- Inorganic active wall thermal insulation materials, cement foam thermal insulation board, glazed hollow bead insulation mortar, rock wool plate, glass wool plate etc., if used for external wall thermal insulation, rock wool board more frequently used.
