Q: What are the fire endurance requirements of class A fire resistant door ?: The fire endurance of class A fire resistance door is 1.5H, but also depends on the product quality. The filling material of class A, B, C fire doors is the same, new fireproofing material-- perlite. The difference is their thickness. The general structure is: surface panel, fireproof?board framework (filled with perlite) fireproof?board panel. !

Q: How much is refractory spraying coatings?: Price: 1400.00 yuan refractory spraying coating brand / model: Jinshi fire resistant material| Brand: Jinshi fire resistant materials | Place of production: Henan refractory temperature: 1200 ~ 1400 (℃) | Material: Customization according to your needs Price: 2150.00 yuan refractory spraying coating brand / model: Tagore | thermal conductivity coefficient (at room temperature): 0.035W / (m · k) | refractory temperature: 1580～1770℃（℃）Price: 122.00 yuan refractory spraying coating brand / model: Jinshi | Tensile strength: | Compressive strength: tearing strength: Excellent | Temperature: 1000 ℃ | Form: Fibrous The above prices obtained from the Internet are for reference only, and please pay attention to the purchasing price.

Q: What problems should be paid attention to while using refractory materials under a controlled atmosphere?: Pay attention to the performance of the materials, and the use of non oxide materials!

Q: which kind of fire?bulkhead is better?: General business fire endurance of two products are 3 hours. Organic fire bulkhead's main ingredient is organic material, which can be used in anti-corrosion and fireproofing cable tray. Inorganic fire?bulkhead's main ingredient is inorganic material, which mianly play a role of fireproofing. It's main ingredient is inorganic material, so it can't be used in acidproof and alkali resistant projects. Of course, the price of same amount organic fire?bulkhead in general is more expensive than the inorganic fire?bulkhead.

Q: What are the requirements of the performances of brasque refractory?: Physical properties of refractory include structural properties, thermal properties, mechanical properties, usability and operation property. The selection of the brasque refractory must have the following characteristics: 1. properties of not distortion and not melting at sufficient temperatures 2. have the necessary structural strength at high temperatures and does not soften and deform 3. must keep stable volume at high temperatures and will notcrack caused by expansion and contraction 4. will not rapture and flake when temperature is drasticly changed or heated unevenly 5. resistant to chemical erosion of metallic solution, slag and furnace gas, etc.

Q: How to apply the alumina powder on refractories?: The most common one in use is the refractory bricks.

Q: What are the characteristics of the carbon composite refractories?: The features of carbon composite refractories: 1. It is with an aggressive high thermal shock resistance 2. Good resistance to molten steel and slag

Q: What is refractory aggregate?: It includes two categories: coarse aggregate and fine aggregate.

Q: What types does refractory floor include?: It includes ecoplates, chipboard,density board, composite?board, etc. Wherein ECO-plate is solid wood board, and it is environmetanl and healthy. Its nail-holding ability and flatness is much better than that of chipboard and solid wood particle board. After all it is solid wood board. But we must pay attention to whether the eco-board is produced in the original factory. According to our original factory, the board only produced by Treezo Group and Dede board are the original.

Q: What are fire resistant level standards of class A fire resistant door?: Situations under which fire endurance should at least meet class A fire resistant door standard: In basement, the fire door for room where the stored combustibles average weight exceeds 30kg/㎡; in partition basement, the fire door for partition of room where the stored combustibles average weight exceeds 30kg/㎡; in high building, the fire door for equipment room of automatic fire extinguishing system, fan room and air-conditioner room; in boiler room, transformer?cabin, diesel?generator room(other dangerous rooms), the fire door in firewall. These places are special and need high security, so they need to meet the standard of class A fire resistant door. What is class A fire resistant door? New Standard for Fire Door GB12955-2008 provides that class A fire resistant door thermal insulation and refractory integrity should be no less than 1.5 hours. In other words, the key of fire door grade is the fire-resistant time. Class A fire resistant door size: class A fire resistant doors have many sizes, and can be customized according to the needs of customers. For example, the size of some fire doors of the diesel generator room is large, while the size of fire doors of basement storing combustibles is small. So the size of class A fire resistant door is also different. Usually Xinduo will take this into account, produce class A fire resistant door with various sizes and can customize according to customer requirements. Class A fire resistant door standard: as is mentioned above, for class A fire resistant door standard, the key is the fire resistant time, no less than 1.5 hours. In texture, class A fire resistant door standard is manifested in the firm joint, uniform distribution of solder joints and smooth surface coating. It has also set fireproof sealing strip which should be straight.
