- Q: How long usually will the A-level fireproof materials prevent the flame?
- The classification of A-level materials is based on GB8624 - 2006 building materials and products combustion performance of grading method. Specific technical requirements are: 1, temperature ≤30 degrees; mass loss rate ≤50%; continuous burning time is 0; 2, the gross calorific value of main components, overall products, external non-substantial components ≤2.0MJ / kg; any internal non-substantial component ≤1.4MJ / kg;
- Q: Can I use ordinary cement with the addition of sand, clay, and salt as refractory material to paste the stove?
- You can add some animal hair, like bristles. After all, we don’t have so much hair. Remember not to use cement, because it will crack. Instead, make use of animal hair, lime, yellow mud and sand, after mixing up, and they would be firmer while in calcination.
- Q: What is the material of fire resistant glass reinforced plastics grating?
- What is the material of fire resistant glass reinforced plastics grating?
- Q: Which are roofing fireproofing material?
- (1) Foamed concrete is a kind of fire-proof thermal inuslation matertial featured by good fire resistance and thermal insulation. Besides, it is also characterized by excellent sound proofing, penetration resistance, easy construction, safety and environmental protection without toxin and pollution. (2) Foam glass is featured by light weight, small heat conductivity coefficient and water absorbption, non-inflammability, fire resistance, high strength, no moulding, corrosion resistance, non-toxin and stable physical and chemical properties and thus widely used petroleum, chemical engineering and underground construction. It is also featured by thermal insualtion, heat/cold preservation and sound absorbption and thus can be used for thermal insulation of external wall and roof of civil builduing. Foam glass is featured by stable chemical property, easy to be processed and not easy to deforme, and durable. (3) With slag, basalt and other natural ore as the main raw material, rock wool, mineral wool and its products are made by high temperature melting into fiber, and then processing with binder. It has low thermal conductivity, fire resistance, easy construction and good effects of energy saving and thus is highly cost-effective. (4) With phenolic foam material as main material, phenolic resin plate is made by foaming thermoset phenolic resin. It is featured by light weight, fire resistance, no burning in the air, no smoking, non-toxin, no dropping and non-embrittlement and thus is an ideal thermal insulation material used in HAVC projects. Due to its high obturator formamen rate, low heat conductivity coefficient, good thermal insulation, water resistance and water vapor permeability, phenolic foam is an ideal thermal insulation material.
- Q: Why should graphitic refractory materials be used now that graphite can burn?
- In theory, any substance can burn as long as certain temperature is reached. Graphite is turned from diamond under anaerobic condition and at high temperature of 2 000 ~ 3 000 ℃. that is to say, ignition point of graphite (lamellar graphite ) under anaerobic condition will be at least above 3 000 ℃. There are many types of graphite, and their ignition points are also different. Ignition point of pyrolytic graphite is much low. Except for a few cutting-edge areas, fire endurance demand for most areas in daily life (eg. brake pad will add a certain amount of graphite) is under 1000 ℃. Therefore, graphite can be used as refractory material. That is, graphite can both burn and can be used as refractory material, which are not contradictory.
- Q: Who can tell me the properties and classification of insulating refractories?
- Insulation materials can be classified according to service temperature, production process and application fields.
- Q: How can the furnace be replaced after the gasifier or water wall is replaced with refractory material?
- The furnace shall be made according to the type of refractory and the moisture content and the type of bond. Pay special attention to the discharge of free water and crystalline water, not too fast to prevent cracks!
- Q: What is the biggest difference between refractory bricks and clay refractory bricks? Where can I find information on the refractory bricks?
- You can look up knowledge manual of refractory material to find phosphatic material, etc. Xinjiang refractory bricks, castable refractory, refractory material, silicious, corundum and alumina-magnesia: High alumina and clay refractory bricks can be divided into
- Q: What kinds of refractory materials that uses a-Al2o3 powder? What are the purpose of it?
- 04La-Al2O3 powder is a alumina powder whose raw material is industrial aluminum oxide which has been calcined at high temperature. It is a good polishes for ceramics and jade, meanwhile, it is also an important raw material for high-end refractory materials. The technical indicators parameters A1023 mark A1535 chemical composition AL2O3≥ 99.92 3%, ≥ 3.10FE203≤ 0.799 Refractory calcined alumina powder (a-Al2O3) 1.2 true density (g & # 47, by fully ground powder made of different fineness .O.10 0.07 0.04NA2O≤ 0.93a-Al2O3 (%) ≥ 95 95 primary crystallization average grain (um) 2 ~ 3 3 ~ 5 average particle size (um) 40 ~ 602.6SIO2≤ 0.1 0.15B2O3≤ - 0, glass, engineering ceramics typical use electronic ceramic insulating ceramic refractory ceramic wear 3
- Q: How to divide fire resistant level of fire door?
- The classification of fire resistant level of fire door: Grade A is not less than 1.2h. Grade B is not less than 0.9h. Grade C is not less than 0.6h. It is suitable for fire door with different levels: Grade A: Equipment room (such as fire-pump room,power distribution room, generator room, smoke control fan room, etc) door, fire?compartment, door on firewall; Grade B: Eclosed staircase, front door of stair room, smoke-proof?staircase and fire elevator share lobby door, front door of fire elevator, household door which directly opens to front room or shares room; Grade C: The vertical shaft door, such as strong electric wells, weak electric wells, pipe shaft door and air conditioning facilities. I hope this information can help you.
