- Q: What are the fire endurance requirements of class A fire resistant door ?
- Hardwares are professional fire resistant lock, fireproof?door closer, fire hinge, handle, latch and sequencer, and they can also be configured according to user needs. Fire resistant time of class A and B fire resitant door is 12h and 09h respectively. It can also be customized according to customer needs into a variety of non-standard specifications. Steel fire door is developed in accordance with the national standard GB12955-2008, and in line with ISO3008, BS476 standards. Requirement: fire endurance should meet the A,B and C fireproof requirements respectively. You can also choose to install hold-open door device to leep the door leaf usually in open. Doorframe and door leaf is made up of imported or domestic quality electrolytic steel plate, electro galvanized steel plate or stainless?steel plate, filled with quality expanded perlite fireproof?panel which can withstand high temperature above 1200 ℃. The surface is processd with electrostatic spraying plastics, and auxiliaries are stainless steel fire resistant lock (or pipe shaft lock ) , galvanization for steel (or stainless?steel) fire hinge, domestic(or imported) door?closer.
- Q: What are the models of refractory cables?
- There are bout four types. 1.NA-YJV / NB-YJV Crosslinked polyethylene insulated PVC sheath A (B) class fire-resistant power cable 2.NA-YJV22 / NB-YJV22 Crosslinked polyethylene insulated steel belt braiding PVC sheath A (B) class fire-resistant power cable 3.WDNA-YJY / WDNB-YJY Crosslinked polyethylene insulated polyolefin sheath A (B) class low smoke no halogen fire retardant power cable 4.WDNA-YJY23 / WDNB-YJY23 Crosslinked polyethylene insulated steel belt braiding polyolefin sheath A (B) class low smoke no halogen fire retardant power cable
- Q: The mechanism and function of antioxidants in carbon containing composite refractories are briefly described.
- With the advantages of carbon refractories especially excellent slag resistance and high heat stability, but graphite under high temperature oxidation, in order to improve the oxidation resistance of carbon composite refractory materials, often adding a small amount of antioxidants, to improve the oxidation resistance of carbon composite refractories. Antioxidant additives commonly used in metal powder, silicon powder, magnesium powder, silicon carbide powder and so on.
- Q: What is special refractories?
- Long nozzle, slidding plate, tapping hole, stopper rods, and products that steel mills use
- Q: Who knows about the fire endurance of grade C fire doors?
- The fire endurance of grade C fire doors is no less than 0.5 hours. As the key role of family fireproofing, fire doors is particularly important. It can be classified according to the fire endurance and thermal insulation performance: The fire endurance of grade A fire doors is not less than 1.5 hours; that of grade B fire doors is not less than 1.0 hours; and that of grade C fire doors is not less than 0.5 hours. We can choose in accordance with different needs, but commonly used fire doors are grade A and B fire doors now.
- Q: How many grades of fire?rating are there for interior decoration materials?
- It can be divided into structural material and base?material based on materials. It can also be divided into flammable, flame retardant and non-combustible materials based on fireproof types. There is no fire?rating for materials. But lengths of time of flammability limits are different.
- Q: Does anyone know what is the use of waste refractory materials?
- 1.Waste refractory bricks can be reused to make the refractory bricks after being crushed by crusher, but the price is not very high. The purchasing price of refractory plant is ?60/ton. Because the refractory material has been calcinated for two times, it becomes easier to make bricks expansion coefficient with waste refractory bricks, but too much is inadvisable. If too much, the refractory materials would have a bad combination, which will give rise to loose bricks and incomplete corners. Nowadays, ordinary refractory plants would purchase waste refractory bricks to produce bricks, but better plants wouldn’t do this.
- Q: How many levels are there in the classification of PP fireproof materials?
- PP fireproof materials level V-0: After two 10-second fame tests on the sample, the flame extinguishes within 30 seconds. Inflamer can not drop. V-1: After two 10-second flame tests on the sample, the flame extinguishes within 60 seconds. Inflamer can not drop. V-2: After two 10-second flame tests on the sample, the flame extinguishes within 60 seconds. Inflamer can drop.
- Q: Pals who know something about fire resistant material please tell me how many types of refractory material there are
- Classified into ordinary and special refractories. The ordinary refractory material is calssified into acid, neutral and alkaline according to the chemical property. Special refractory material is calssified into high temperature oxide according to the composition for , infusible compound and high temperature composite in addition, can be divided into ordinary refractory products according to the fire intensity (1580 ~ 1770 DEG C), high-grade refractory products (1770 ~ 2000 DEG C) and special refractory products (2000 DEG C above). According to the products shape can be divided into bulk (standard brick, special-shaped brick block, special shape (crucible, sagger, pipe, etc), fibrous shape (silicates of aluminum and zirconium oxide and boron carbide matter) and irregular shape (fireclay, refractory castables and incompletely material).
- Q: What is the biggest difference between refractory bricks and clay refractory bricks? Where can I find information on the refractory bricks?
- You can look up knowledge manual of refractory material to find phosphatic material, etc. Xinjiang refractory bricks, castable refractory, refractory material, silicious, corundum and alumina-magnesia: High alumina and clay refractory bricks can be divided into
