Heat Insulation Ceramic Fiber Blanket Price

Q:What are the construction measures of refractory material in winter? Please descriptive briefly.: The temperature is low in winter, so refractory bulk materials should be stirred evenly on time to avoid freezing.

Q:what is the fireproofing material of engine room? who knows it ?: 1. The new type fire?retardant?coating in fire retardant coating, the expanded vermiculite, expanded perlite heat insulation material and cenosphere adiabatic powder, etc. These inorganic component, is a major part of the thick coating type of fireproof coating, and they also are the major factor affecting the level of performance of fireproof coatings. The fireproofing thermal insulation properties of fireproof coating, is mainly determined by the fire back surface temperature of this factor, but also related to the fire endurance. If it reaches the same temperature for a longer time, it shows that it's fireproof thermal insulation is better, and the fire endurance therefore is higher. 2. The new fireproof board new fireproof board now is welcomed by the people and the important factor is its environmental protection, and with the increasing high-rise buildings, the fire protection requirements and strength requirements are also rising, it is a big challenge for the performance and standard of the fireproof board.. Now fireproof board is mainly used siliceous material or calcareous materials, and then mixed with the fiber material, lightweight aggregate, adhesives and chemical additives, it is not only be fireproofing, but also improve their thermal insulation performance, and light weight, good carrying capacity, good durability, no aging problem, more importantly, it is good in environmental protection.

Q:Who knows about the grade C fireproof door materials?: Wood or steel materials are usually used in them. The new national standard fire doors: According to the enacted GB12955-2008, the fire endurance of grade C fire doors is 0.5 hours and that of grade A and B are 1.5 hours and 1.0 hours respectively.

Q:How to classify fire resistance rating of brick-concrete structure?: In order to ensure the safety of the building, the fire protection measures must be taken to make it have a certain degree of fire resistance, even if there is a fire, it will not cause too much damage. According to the national conditions of our country, and in the light of other countries standards, < high-rise civil building fire protection design specification > defines fireproof rank of high-rise civil buildings into level one and two; < code for fire protection design of buildings > divides the rank into level one, two, three, four, level one is the highest level, level four is the lowest. Besides that the minimum fire resistance of the building component is specified, buildings of fire resistance rating also specified requirements for combustion performance. Because the component with the same fire resistance limit is different, it is different in the fire.According to our country national standard < building design fire protection code >, the fire resistance rating of the building is divided into four levels. The fire resistance of a building is determined by the combustion performance and fire resistance of building components (such as beams, columns, floors, walls, etc.). Generally speaking, the fire resistance building of level one is a mixed structure of reinforced concrete structure or a mixture of brick wall and steel concrete structure; the fire resistance building of level two is a mixed structure of steel truss structure, reinforced concrete column and brick wall; the fire resistance building of level three is brick-wood structure made of wood roof and brick wall; the fire resistance building of level four is combustible structure which is composed of wood roof and non-combustible wall.

Q:What antioxidant will be used in refractories?: Antioxidant: Si, Al, Mg, Ti, AlSi, AlMg, SiC, TiC, ZrC and these metal nitride, boride. Sintering agent: different mechanism, Cr2O3 to promote the sintering of alumina;CaO/MgO style promote ZrO sintering;Siliceous ramming material to add boron bottles, magnesia coating and clay, etc.

Q:how is the high-temperature flame-retardant fibre board?: The market is mainly divided into three kind of fiber. Density fiberboard, medium density fiberboard, high density fiberboard. Density fiberboard: It is rolled timber sheet made of wood shaving material produced by timber or non timber fiber that is added with or without glue or auxiliary material. A density of less than 450 kg / cubic meter, the larger fiber particles, the internal structure is not homogeneous, relatively lack of strength, lighter weight. MDF: use wood fiber or other plant fiber as material, added with glue. A sheet pressed at high temperature and pressure. A density between 450-880 kg / cubic meter, fiber particles is moderate, well proportioned internal structure, greater strength, moderate weight. HDF: Use wood fiber or other plant fiber as material, added with glue. A sheet pressed at high temperature and pressure. Its density is about 880 kg / cubic meter, small fiber particles, well proportioned internal structure, greater strength, greater weight. there are also artificial boards such as chipboard and melamine board in the market, generally used for making furnitures. the thickness of fiberboard that is produced and controlled more flexibly, is generally 5 per cent (general bulk price of 30 yuan per square meter), 9 cm (50 yuan), 18 cm (100), 25 cm (120), etc. There are thicker. However, proper deviation is acceptable. The board is usually thicker or thinner than the specified thickness. For example, It is only 16mm when specified 18mm.

Q:What are refractory materials?: Refractories can be divided to two categories based on the shape and three categories according to the chemical nature of acidity, neutralily and alkalinity. Alkaline refractory materials are magnesia-carbon brick, magnesia chrome brick, calcium magnesium brick and magnesia-chrome bricks. Neutural refractory mateial are high alumina brick, corundum brick and clay brick. Case-hardened refractory materials are castable, ramming mass, gunning mix, coated mix, dry vibration material, etc.

Q:As for fireproofing material rock wool and glass wool, which one is better?: As for fireproofing effect, the effect of rock wool is certainly better than glass wool , the highest temperature of rock wool is 1100 ℃, but the temperature of glass wool is only 600 ℃. In addition, if it's used in the external walls, then,unit weight of the glass wool is limited,and high unit weight can only be 60-90, but unit weight of rock wool can reach over 140, now external wall can't use glass wool, and only rock wool is A class fireproofing material. glass wool has lower thermal conductivity, rock wool has longer fiber length,as for the price, tons price of glass wool is more expensive than rock wool, but if it's acculated by square, square price of glass wool is cheaper than rock wool.

Q:What 's the highest temperature can magnesium plate glass resist ?: Glass magnesium plate is non combustible plate having good fire-resisitance quality. Flame will never burn continuously on it. It does not catch on fire when temperature reach 800 ℃, and will not be lit up at 1200 ℃. The plate, having high-quality keel partition system, is rated as the highest non-combustible level A1 with fire resistance being above 3 hours. It absorbs a lot of heat when fire is burning, delaying rise of ambient temperature.

Q:How many refractory materials does the annual output of 1 million tons of coke oven require?: The production of dense synthetic Magnesium Oxide requires many steps, briefly summarized as follows:(1) Mgcl2+Ca, Mg (OH) 2, =Mg (OH) 2+CaCl2Sea salt or brine, dolomite, magnesium hydroxide, residual salt(2) Mg (OH) 2 Mg0 (low density);(3) MgO, Mgo (compact)The resulting compact Magnesium Oxide generally has a purity of up to 95%-99%, depending on the manufacturing process and the final application requirements. As shown above, Magnesium Oxide can be obtained from sea water and slaked lime. The density of the final product is through the high temperature roasting in shaft furnace and the large area obtained by calcination, and the mechanical compaction. Through the pre sintered refractory material to fundamentally eliminate the permanent contraction or extension is extremely important, it is obviously, because we cannot expect excessive contraction or extension in the use of the materials can be used to store the proper degree of molten metal or slag. The production of magnesium oxygen throughout the world (Fang Meishi) large factories in the United States, Michigan by brine well production, and by the sea water production Magnesium Oxide factory is located in Florida, Texas, California and Maryland.
