Q:Who knows the grade of pipe insulation materials, the distinction between the specific basis and the exact value. Urgent, thank you

Depends on the level of norms. Friend, why do you do that god?

Q:Insulation class fire rating non - combustible A - level and A2 - level difference

A1 and A2 difference: 1. Light rock wool board is A1; 2. Rock wool composite board is A2 level; so A2 refers to the A1 level and another material of the complex, grade lower than A1.

Q:What are the fireproof materials?

Inorganic binder: mainly water glass, gypsum, phosphate, cement, etc .; refractory mineral fillers: alumina, asbestos powder, calcium carbonate, perlite, white powder, etc .; flame retardant organic resin: Ethylene, perchlorethylene, chlorinated rubber, neoprene latex, epoxy resin, phenolic resin and the like. (Chlorinated paraffin, tributyl phosphate, decabromodiphenyl ether), and boron (boric acid, dibromide), boron, Zinc borate, aluminum borate), antimony, aluminum, zirconium and other inorganic compounds.

Q:Wood-plastic material fire?

Fire rating is classified. Can not simply say that wood-plastic material fire or not. According to the composition of wood-plastic materials, which is mainly plastic and wood powder, in order to increase the fire resistance of wood-plastic, plus a certain amount of flame retardants, but the type and number of flame retardants and a direct impact on the fire for the box The performance of the valley. At present, many wood-plastic materials, the highest level of fire should be in the B1 level, the need for a stronger fire rating, then the need for special formula, many companies can not do a class A fire rating. Detailed advice ::

Q:Fire protection requirements for indoor ceiling materials

In all the interior decoration of the fire design, the ceiling of the fire design in the most important position. This is because the fire is burning up the fire, the ceiling first and directly accept the fire test; the same time, there is a direct impact on the evacuation, will directly constitute a threat to the safety of evacuated personnel. Therefore, in the interior ceiling decoration design, should give full consideration to its fire problem. "Fire protection within the building design fire code" on the different civil buildings of indoor ceiling material fire performance has a detailed requirement. Ceiling (prungroof), refers to the roof of the living environment of the decoration. The ceiling is an important sub-division of the building decoration project. The ceiling has the function of insulation, insulation, sound insulation and sound absorption. It is also a hidden layer of electrical, ventilation and air conditioning, communication and fire prevention, alarm pipeline equipment and so on. The ceiling in the whole room decoration occupies a very important position on the top of the room for the appropriate decoration, not only to beautify the indoor environment, but also create a colorful interior space art image. In the choice of ceiling decoration materials and design programs, to follow the two materials, solid, safe, and beautiful, practical principles.

Q:Short point is to do hand copy

Several common fire fighting methods: 1, furniture, bedding and other fire: the general use of water fire. With water around the items such as the basin and so on to the flame on the water, but also the water pipe connected to the faucet sprinkler fire; at the same time the burning point near the combustible humidification. But the oil, electrical fire can not use water to fire. 2, electrical fire: household appliances or lines on fire, we must first cut off the power, and then dry powder or gas fire extinguisher, can not directly splash water to prevent electric shock or electrical explosion wounding. 3, the TV fire: TV in case of fire, never water, you can cut off the power, with a quilt to cover it. Fire, only from the side close to the TV, to prevent the camera tube explosion wounding. If the use of fire extinguishers fire, should not be directed to the TV screen, so as to avoid the sudden cold after the heat and explosion. 4, the pan fire: the oil pan should quickly shut down the stove gas valve, directly cover the lid or cover with a wet cloth, but also to the pot put the chopped vegetables to cool the fire, the pot smooth from the fire, After cooling to open the lid, do not pour water to the oil pan. 5, gas tank fire: use wet bedding, clothing and other cover fire, and quickly close the valve. 6, the body of the fire, do not run around, can be used to roll or heavy clothing to suppress the flames. Wearing a wet towel, handkerchief and so cover your nose and mouth, try to make the body close to the ground, bending or creeping forward.

Q:Is the soundproof cotton a fireproof material?

There is fire, there is no fire.

Q:Extruded board fire B1, B2 grade material how to distinguish

Extrusion board fire B1, B2 grade material distinction: B2 level for the slow combustion level, that is, after the fire will not become larger, and the drop will not ignite the filter paper; B1 level from the asphyxia, that is, leave the fire After the automatic extinguished, or 10 seconds off. Extruded board is extruded polystyrene insulation board, it is polystyrene resin as raw materials with other raw materials and additives, through a special process of heating at the same time into the catalyst, and then continuous extrusion (XPS), XPS has a perfect closed-cell honeycomb structure, this structure allows the XPS board has a very low water absorption. It is known as the thermal insulation with extruded polystyrene foam (XPS) (Almost no water absorption), moisture-proof, airtight, light, corrosion resistance, low thermal conductivity, high pressure resistance, anti-aging (normal use almost no aging decomposition), long life, low thermal conductivity Energy saving and environmental protection insulation materials. Due to the continuous extrusion caused by the tight closed-cell structure. Its density, water absorption, thermal conductivity and steam permeability are lower than other types of sheet metal, is the market recognized the best insulation materials. Extruded board of fire grade classification is more detailed, there are B3, B2, B1 three levels (A level on the current science and technology can not be achieved), which B3 level for the ordinary board, that is, the fire, and the fire is growing ; B2 level for the slow combustion level, that is, after the point of fire will not become larger, and the drop will not ignite the filter paper; B1 level from the asphyxiation level, that is, after leaving the fire automatically extinguished, or 10 seconds off.

Q:Outdoor steel ladder as a fire evacuation ladder has any requirements

Outdoor evacuation staircase set requirements: (1) stairs and each floor of the export platform application of non-combustible materials production. The fire resistance of the platform should not be less than 1h. (2) in the stairs around 2m within the wall, in addition to evacuation door, should not open other doors and windows openings. The evacuation doors shall be of Class B fire doors and shall not be on the stairs. (3) the minimum net width of the stairs should not be less than 0.9m, the tilt angle should not be greater than 45 °, railings should not be less than the height of 1.1m.
