- Q: What kinds of fireproof and fire retardant materials are there?
- recommend new Nano-insulation refractory insulation material Aerogel material, which consists of 99% pores of different sizes. it is not only the lightest and the most remarkable insualting material, but also having hydrophobic porous particles. 1830s invention.It has low thermal conductivity,not susceptibale to electrical, thermal and impact of sound with strong physical stability. It is a good insulator, but also has a strong impact resistance, three times the weight of the same volume of air. It is not heavy and can be used as heat insualting materials,buffer?materials, sound proof materials. It has attracted world attention and will be widely used in the future. Aerogel (Aerogel) features: Nontoxic to humans, insoluble in water, no burning, odorless, the world's lightest, low thermal conductivity. Aerogel heat shield is a new industrial insulation products. New products based on nanotechnology materials Aerogel, Aerogel materials in foreign countries has been widely used. We find it a lot better than the traditional insulation materials. To this end, the company introduced the product to China to open the Chinese market and import the best insualting materials to oil refining, electric power, shipbuilding, chemical, industrial pipelines, aerospace, machinery and equipment industries.
- Q: Concrete composition and function of magnesia bond used in refractory
- According to the chemical composition and use can be divided into metallurgical magnesia, magnesia brick, magnesia brick, magnesia brick, magnesia calcium brick, magnesia brick and other varieties. Its performance is greatly affected by CaO/SiO2 ratio and impurities. High purity magnesia brick refractoriness under load and thermal shock resistance are better than the general magnesia brick. High refractoriness, has good resistance to alkaline slag and iron slag, is a kind of important senior refractories. Use of magnesia product production by sintering process, sintering temperature is 1500 ~ 1800 DEG C, in addition, you can also add chemical bond, made of brick and unshaped refractory material. Mainly used in open hearth furnace, electric furnace, converter, oxidation non-ferrous metal smelting furnace, cement kiln and alkaline refractory kiln etc..
- 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: How long is the duration of fire resistance that fireproof door of level B can endure?
- According to the duration of fire resistance, fireproof doors can be divided into three levels, namely level A,B,C. And accordingly, the duration of fire resistance of them should not lower than 1.20h, 0.90h and 0.60h. Fireproof door, a door that can meet the requirements of fire resistance stability, fireproof door integrity and thermal insulation at a certain time, is a fireproof separator which is located in fireproof partition, emergency staircase and vertical silo. Apart from functioning as a common door, a fireproof can also prevent the spread of fire and smoke in a certain period to make sure that people are safely evacuated.
- Q: What are grade classifications of the external walls for fireproofing?
- The basic level can be divided into: A1, A2, B1, B2, B3 and other levels. There are many technical indicators to make specific division, but I partly cannot report for a while, because it is very professional and technical. Please contact Qingdao Shanfang Instrument Co., LTD for details, they specialized in the external wall thermal insulation materials fire?rating testers.
- Q: Manganese steel belongs to refractories
- Material wear and other harsh working conditions, extrusion, there will be work-hardening phenomenon rapidly on the surface. The most important feature of manganese steel is that it is not refractory under a strong impact, and under extrusion conditions, part of it will be fractured. The main form of damage is wear and consumption: It is a kind of inorganic non-metallic material whose refractoriness is not lower than 1580 ℃, mainly used to endure impact. Manganese steel is a kind of high strength steel, which is free of deformation, so that it can remain austenite good toughness and ductility at heart while keeping good wear resistance at the same time on hardened layer. Refractories are
- Q: Who knows about the fire endurance of grade C fire doors?
- The fire endurance of grade C fire doors is no less than 0.5 hours. As the key role of family fireproofing, fire doors is particularly important. It can be classified according to the fire endurance and thermal insulation performance: The fire endurance of grade A fire doors is not less than 1.5 hours; that of grade B fire doors is not less than 1.0 hours; and that of grade C fire doors is not less than 0.5 hours. We can choose in accordance with different needs, but commonly used fire doors are grade A and B fire doors now.
- Q: What's the heat conductivity coefficient, specific heat capacity and density of the refractory material of magnesite-chrome brick and magnesia-alumina brick respectively?
- It is suggested that you find some samples of well-known manufacturers, such as Ogilvy and Mather Group, and that will be more correct.
- Q: What types does soft fire prevention materials have?
- Soft type fire resistant species. Finishing fire retardant paint, component fire retardant coating, fire-resistant coating for steel structure and othe kinds of fire retardant coating. Flame retardant plastics and its products, textiles, building materials, flame retardant fabric and exterior wall thermal insulation system products, floor materials, such as various types of fire prevention materials;Fire prevention board, fire doors, fire prevention, fire shutter, fire glass window frame, elevator doors, ventilation pipes, fire blocking material, fire smoke exhaust fan and other kinds of artifacts (resistance) fire prevention.
- Q: Does the aluminum silicate thermal insulation material fireproof?
- With stable performance,long fiber length, strong tensile strength, strong seismic performance, low shot, light unit weight, low thermal conductivity, good insulation properties. it is not bad.
