- Q: How many kinds of fireproof materials are there in the market?
- I wonder that how many kinds of fireproof materials are there? Does anyone know about it, please tell me, thanks
- Q: What kind of material is good for cabinet fireproof board
- What kind of material is good for cabinet fireproof board What are the advantages and disadvantages of using it? How much is the price? A about how much does one piece cost?
- Q: Refractory materials are needed for casting metallurgy.
- Refractory material used in foundry work is that refractories for cupola furnace? Cupola is a high temperature furnace which is used for melting molten iron, and refractory material adopted is mainly low iron high grade clay brick and clay lightweight insulation bricks, etc.foundry ingot refractory material is pearl sand (also known as pearl jewelry sand, fused ceramic, ceramic sand) it is made of high quality bauxite material by arc melting furnace.
- Q: Who knows about the criteria of fireproof and thermal insulation materials?
- Seven levels are divided according to "The classification of combustion performance of building materials and products", namely, A1, A2, B, C, D, E, F. It mainly refers to the combustion performance of materials. You can check on this standard for the specific dividing evidence. There are detail charts which mainly describe that whether there is drip or not, the ignition time, continuous burning time and so on.
- Q: What materials are needed to make the amorphous refractory bricks?
- I am so glad to answer your question. The amorphous refractory brick is composed of a certain proportion of aggregate and powder, a binder and an additive.
- Q: How is the performance of refractory materials?
- It is a little difficult to answer. There are some requirement for refractory materials, such as fire resistance, softness, creep, thermal shock, abrasive resistance. Besides, requirements for construction performance include: Liquidity, plasticity and other linear change rate, volume density, strength (including high temperature) and all other important indicators must be tested the same conditions with the use of test conditions and test items like body density, strength, line changes in the basic project
- 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 are the types of refractory sealant?
- Refractory sealant has low exothermicity and will form a hard corking content during burning, it includes: Liquid polysiloxane has at least two active groups selected from alkoxy, hydroxy and alkenyl; a cross-linking agent, a catalyst, a reinforcing filler and wollastonite. These cured silicone rubber sealant has low heat release and will form a hard coking content structure while buring. Refractory sealant composition can be used in sealing structure to prevent flames, air and other steams passing. 1. In a liquid organic polysiloxane polymeters, each R1 is independently selected from the alkyl, aryl, alkenyl and haloalky which has 1-18 carbon atoms, and each R2 is independently selected from the hydroxy, alkoxy, alkenyl, and X is an integer from about 10 to 1,500. 2. A crosslinking silicone compound having at least 3 silicon-bonded eactive groups. 3. A R2 pressed of silicon bonding capable of promoting component A. 4. Wollastonite and a selective reinforcing filler.
- Q: What are the requirements when producing fireproof materials by kaolin?
- . Kaolin are kaolinite crowded mineral composed of tiny flakes tubulose, lamellar smaller than 2 microns. it is composed of kaolinite, dickite, pearl stone, halloysite etc. I chemical formula of which is AL2O3-2SiO2-2H2O, the main mineral component is kaolinite and halloysite. Except kaolinite and halloysite there are other minerals montmorillonite, illite, pyrophyllite, quartz and feldspar associated. kaolin contains large amounts of the chemical composition AL2O3, SiO2, and a small amount of Fe2O3, TiO2, and small amounts of K2O, Na2O, CaO and MgO, etc. white pottery is made of kaolin and is now internationally accepted scientific name --Kaolin, derived from the eastern suburb of Jingdezhen high-Village side of the mountain kaolinite. kaolin plasticity, cohesiveness, certain dry strength, sinterability and whiteness after burning, making it the main raw material for ceramic production;. white, soft, highly dispersed, adsorption and chemical resistance with other excellent process performance, it has been widely used in the paper industry as well as industrial sectors such as agriculture and defense cutting-edge technology in the field of rubber, plastics, refractories, petroleum refining . according to the purpose and need, it can be processed, treated and purified, they can be used to produce activated clay.
- 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.
