- Q: Preparation of refractory clay
- Is it to make refractories? Add some andalusite to the refractory mortar will improve the effect.
- Q: What is the main constituent of refractory brick?
- Primarily magnesium oxide and sodium silicate as binder.
- Q: Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?
- Solid wood logs are necessary. If it is the type of smoke free material, it will not be necessary. You'd better confirm it with the port of destination. Vietnam has the requirement to smoke
- Q: How much is the content of boron carbide in refractory material?
- Boron carbide is used in refractory material. For example, generally we could add 0.2% of boron carbide into magnesia carbon bricks. It is suggested that 0.5% is enough, because it has strong effect in boosting melt. It is said that 0.5% would be alright since boron oxide after oxidation belongs to material of low melting point, so the amount should be limited within 0.5%-1%,
- Q: How to distinguish the fire?rating of rubber and plastic thermal insulation material?
- It is divided into level A, B1, B2 and B3. According to the current "burning behavior of building materials classification method", Level A insulation material is a non-combustible material, which belongs to YT. However, from the point of view of the current market , level A insulation material are very few, only glass wool, rock wool board, foam glass and vitrified micro bead. However, compared with level A insulation material, the more welcomed by the market is the organic insulation material. This is characterized as thermal insulation material, which is divided into three levels: level B1 is flame retardant, level B2 is flammable and level B3 is flammable. The level B1 nonflammable thermal insulation material is determined according to the fire endurance of the material. And different parts of the material are divided differently! Such as the common EPS / XPS insulation boards through special treatment of adding flame retardant. . Level B2 combustible insulation material is commonly the EPS expanded polystyrene foam insulation board and XPS board, that is, the ordinary plate. This material has low ignition point, and releases large amounts of harmful gases in the combustion process . Level B3 flammable insulation material is commonly the thermal insulation material taking polystyrene foam as the main material. Since this material is highly flammable, it has been out of the external wall thermal insulation materials. As for the civil construction insulation materials, China's current popular building insulation materials in the market are mainly made of three organic foams: EPS (molded polystyrene board), XPS (extruded polystyrene board) and PU (polyurethane).
- Q: Is there any difference between insulating bricks and refractory bricks? Are there any professional refractories factories that are reliable in the quality and quality of these irritated materials?
- Physical and chemical property indexes of high strength and high alumina refractory bricksProject indexPLG-1.0 PLG-0.8 PLG-0.5 PLG-0.4AI2O3% 56545250Fe2O3%, 2, 2, 1.5, 1.5Bulk density g/cm3 1, 0.8, 0.5, 0.4Normal temperature compressive strength MPa shall be no less than 7531.5A change of a burn line of not greater than 2%The temperature is 1400140012501250 centigradeThe coefficient of thermal conductivity, W/m.k average temperature (350 + 5) is not greater than 0.45, 0.35, 0.25, 0.20
- Q: What is the difference between the fire?rating and the fire resistant level of the fire-fighting equipment?
- Fire rating and fire-fighting rating are the misnomer to the building fire resistant level. The building fire risk is measured by fire resistant level. The article 3.2.1 and 5.1.7 of "Architectural design code for fire protection" have made provision respectively on the fire resistant level of plant (the storeroom) and civil construction. Article 3.0.2 of "Code for fire protection design of tall buildings" has made provisions on the fire resistant level of tall buildings. Fire resistance rating of the building is divided into four levels. Standard of fire resistance rating is determined by the combustion performance and fire resistance of the main housing member. Level one or two are in accordance with the Article 1.0.2 in this specification.
- Q: Is it normal for caable fire resistant material to catch on fire?
- Abnormal, preventive measures: 1 take fire preventive measures. Measures taken for fire retardant measures of cable: (1) seal closely with fire resistant materials holes ran by cables through walls, shafts to prevent the cable fire, high temperature gas diffusion and spread when cables are on fire. (2) to wrap the cable with the insulation refractory material, when the cable is surrounded with fire, warpped cable is insulated by the insulation material from fire, so it will not be burned. If the cable itself is on fire, fire will be extinguished thankes to lack of oxygen in warpped cable, to avoid the fire to spread out. 2 to strengthen the cable circuit switch and regular protective check and maintenance, to ensure that the action is reliable. 3 to strengthen the cable operation and monitoring, to avoid the overload of the cable operation. . 4 regularly clean dust on the cable, to prevent cable from catching on fire due to the accumulation of dust. 5 to ensure the construction quality, the quality the cable must be strictly in line with the requirements and standards. 6 cable laying should maintain enough distance form the heat pipe, control cable is no longer than 0.5 meters; power cable is no longer than l meters. Control cable and power cable should be divided into slots, be layered and seperated instead of being overlapped . For the parts that do not meet the requirements, measures must be taken to insulate heat and fire. 7 regularly teat cable , abnormal problem should be handled in a timely manner. 8 install fire alarm so that fire will be discovered on time, and cables will not catch on fire. 9 the cable trench should be kept dry to prevent the cable from being affected with damp, or leading to declined insulating function and short circuit.
- Q: What is the the best ratio of mortar in refractory cement?
- Specifical proportions are as following: 42.5R cement is 425 rapid hardening cement. Using the 425 cement to compound the mortar. The reducion of cement will naturally impact the workability of the mortar. The mix design standard of the mortar specifies the minimum amount of cement is not less than 200kg / m3. If it is composite mortar, and the strength and workability can be ensured, it is Ok to use 425 to compound. You can look for instructions of mixing proportion of mortar online as a reference.
