- Q: Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?
- See which port, if it is from the border (Pingxiang, Dongxing port), will not be needed.
- Q: Who can tell me about the foundry refractory materials?
- The casting fireproof materials can be divided into three categories in accordance with chemical property, namely, acidic, neutral and alkaline refractories. The commonly used refractories are alkaline and neutral ones, such as alkalic magnesia-carbon bricks, fired magnesite bricks, magnesia-chrome bricks, magnesium-calcium bricks, and neutral high alumina bricks, corundum brick, clay bricks, etc. The shapeless ones include: castable refractory, ramming?mass, gunning mix, coating, and dry vibration material, etc!
- Q: Which industry does refractory belong to?
- It belongs to decoration industry.
- Q: The difference between refractory and thermal insulation material
- In simple terms, refractoriness is different. The refractoriness of refractory is high while that of insulation material is low.
- Q: What is special refractories?
- Long nozzle, slidding plate, tapping hole, stopper rods, and products that steel mills use
- Q: who knows the fire resistant level of fireproof gypsum board ?
- combustion performance of building decoration materials should be divided into four levels: A level, non-flammable; Class B1, flame retardant; B2 level, flammability; B3 level, flammable. Choose the materials above B1level. Thank you
- Q: How is refractory material made?
- It is made by mixing and processing of various refractories.
- Q: What's the fire resistance rating of the exterior fire?retardant?coating?
- Exterior thick fire-resistant coating for steel structure can reach the first level of fire resistance, thin fire-resistant coating for steel structure can be fire-resistant for three hours, and ultra-thin fire-resistant coating for steel structure can just be within the second level of fire resistance.
- 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.
