Q:What are the differences between first-level fire-resistant materials and second-level fire-resistant materials?
Level B1: building materials with flame retardancy: this kinds of materials have good effect in flame retardation. Under the case of open fire or high temperature, it is not easy to be ignited and spread quickly, and when the fire source is removed, fire would stop immediately. Level B2: combustible building materials: combustible building materials also have effect in flame retardation. It will get burnt as soon as it meets open fire or high temperature, so it can easily give rise to rampant fire, such as wooden pillars, wood roof trusses and wooden stairs.
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:What is the type of heat resistance property of high temperature electric furnace ?
According to the levels of refractoriness : Common refractories: & Gt: 1580 ℃ ~ 1770 ℃ advanced refractories: 1770 ℃ ~ 2000 ℃ AAA refractories; 2000 ℃
Q:Introduction to refractory material
The best way to learn is on-site contact. If for produing purpose, it is better to ask teh leader of a plant. If for application, go to steel mill (cement plant, glassworks, etc.) to learn and look up information. Theory alone is of no help.
Q:What are included in wall fireproofing material?
External wall thermal insulation materials are divided into A and B according to combustion level. Grade A is incombustible material, while grade B is combustible material. A few years ago, fires in CCTV building and Shenyang hotel resulted from grade B material. Currently grade A is usually used, and some are even cheaper than the grade B material. Grade A is roughly divided into insulation mortar, phenolic board, rock wool board, foam cement board, etc. Insulation mortar is quite good. It is easy and convenient to construct, has low cost, but the production is too simple and it is easy to fake.
Q:what kind of refractories is used to make the industrial silicon furnace mouth long life?
Fused zirconia corundum brick, the smelter of the glassworks is used this kind of lining, and you can contact by private letter.
Q:How to apply the alumina powder on refractories?
The most common one in use is the refractory bricks.
Q:What is the difference between wear-resistant material and refractory material?
One is to require wear-resistance. It can be both fire-resistant and wear-resistant, and they can enter different categories. Faced with different demands, it has a variety of features. But both can also be integrated. I think many materials have same division. One is fire-resistant. The two concepts are different division. They are not comparable.
Q:What do we mean by saying that a ladle cover knots, elbow knots, blowpipe knots in refractory materials? What is the “knot”?
Blowpipe is also the construction of unshaped refractory materials. Refractory material for ladle cover is light weight heat insulation refractory material. What you said that the construction of bend out refractory materials in some steel mills called "knot".
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.
