- Q: What are unshaped fire-resisitance materials?
- Refractory castable, refractory plastic material, usually classified according to construction and manufacture method, unfired bricks precast block, refractory pressed into material, refractory cast material, refractory coating, refractory ramming material there are many classification methods
- Q: What does fire-resistant insulation coating have?
- Refractory thermal insulation material mainly refers to the inorganic thermal insulation material and composite thermal insulation material. According to the shape, it can be divided into: Finishing of fibrous shape, mineral?cotton, rock wool, glass wool, aluminum?silicate?wool, ceramic fiber, etc. Diatomaceous earth of microporous pile, calcium silicate, expanded perlite,expanded vermiculite,aerated concrete, etc. Foam glass of bubble shape, volcanic ash glass, foamed clay, foamed?concrete, gelatine powder polyphenyl granule heat insulating slurry of pasty form, etc. Their common feature is fire-retardant and firproof. It can be used in buildings with high requirements of fire?rating. Calcium silicate, aluminum silicate and asbestos can also be used for piping insulation of heat transport with high temperature. Hope it is helpful to you.
- Q: How is the division of the fire resistant level of the rock wool board?
- It's like this: China's national standard GB8624-97 divides the combustion performance of building materials into the following grades. Level A: non-flammable building materials. Level B1: flame-retardant building materials. Level B2: combustible?building?materials. Level B3 flammable building materials. section II Combustion performance and fire endurance of building components. First, The combustion performance of buildings of building components. The building is composed of components, such as foundation, walls, lubrication columns, beams, plates, roofs and stairs, ect. Building components are constituted by the building materials, whose combustion performance depends on the combustion properties of the used construction materials. Section One Combustion performance of building components. The building components are divided into three categories according to their combustion properties. First, non-combustible component: the component made by incombustible?materials. The incombustible?material refers to that when meeting the Oxygen in the air, it will not burn.
- Q: What are the new refractories? What are the features? How about their application and development?
- In metallurgy, in what position should it be used, in order to make the best. Answers are as following. In iron, steelmaking or converter. When questioning, pay attention to the ways. Answers: Try to use synthetic refractory materials.
- Q: What are the features of construction class A fire resistant door ?
- 1, fireproof and thermal insulation Foam cement board is a Class A non-combustible inorganic heat preservation material which has good fireproof?performance can remain integrity after 3 hours baking at 1200℃. It can be used in buildings to improve fireproof?performance.
- Q: How to prolong the furnace age of Induction furnace by using fireproof materials?
- magnesia solid materials have thermal endurance and erosion/ performance and its change of temperature is likely to cause cracks. properties of materials (aluminum) in such case have to be taken into consideration.
- Q: What are grade classifications of the external walls for fireproofing?
- The classfication of external wall material fire rating is as follows: Level A: Complete retardant building materials may not occur combustion, and the cost is relatively high, home decoration do not need such a high standard. In general, it can be used in the arms powerhouse and electrical appliance store. Level B1: non-flamble construction material has high flame-retardant, it will not be burn under the conditions of open fire and high temperature, but if it is attacked by these two conditions, it may still be burning. However, when the source of fire is transfered, it will be immediately extinguished. Level B2: Combustible building?materials have a certain degree of flame resistance, but the effect is very little. Under the condition of sufficient air, it will break out fire even in high temperature, such as wood building materials. Level B3: As long as the flammable building materials meet the source of fire or high temperature, it will break out fire. Currently, this product doed not sale on the market. So what are the external wall thermal insulation fireproofing materials? According to several grades, I will give you some specifical examples. Level A insulation material: Glass wool, foam glass, foam cement, hole-closed perlite, rock wool; level B1 : Extruded polystyrene board through special processing, referred to xps. The other is polyurethane through special treatment, referred to pu. In addition, there are phenolic aldehyde and gelatine powder polyphenyl granule; level B2: Polyethylene, referred to pe. Molding polystyrene board, referred to as eps.
- Q: What is the offer of fire proofing thermal insulation material?
- The following prices are from the Internet and for your reference only. Hainan fire proofing thermal insulation material ceramic fiber paper aluminum silicate fiber blanket/aluminum oxide fiber insulation cotton insulation pipe 12 yuan Hainan multicrystal mullite/calcium silicate corundum ceramic fiber loose wool short fiber fire proofing thermal insulation material non-asbestos high temperature resistant aluminum silicate fiber insulation cotton fire-resistant material ceramic fiber blanket thermal insulation blanket 28 yuan non-asbestos high temperature resistant aluminum silicate fiber ceramic fiber blanket needled felts insulation blanket fire resistant material thermal insulation cotton blanket reference price: 59 yuan
- Q: Could you tell me the fire-resisting time of class B fire proof door?
- The fire-resisting time of class B fire proof door is 1h and thickness of door can't be lower than 45mm.
- Q: What is the limit of fireproof rolling shutter?
- Fire proof door can be divided into Serie A, B and C in terms of fire endurance limit, fire resisting limit are not should be less than 1.20h, 0.90h and 0.60h. Set firewall has difficult sites can use fire shutter fire partition separating, when the back fire surface temperature rise refractory limit determination conditions of fire shutter, the fire resistant limit not less than 3H; when employed does not include back fire surface temperature rise do fireproof limit determination conditions of fireproof rolling curtain, on both sides of the shutter should be set up a separate closed type automatic water spraying system protection, sprinkler system continuation of time should not be less than three hours.
