- 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:Graphite and other carbon materials may be oxidized to CO or CO2 at high temperatures. But why can they be refractories?
- There is no contradiction for this. Any substance can be combustible, but different materials have different ignition points.There are many types of graphite. Pyrolytic graphite has a much lower ignition point. Therefore, as long as it reaches at a certain temperature, it can convert into graphite. Mostly, in practical applications (such as brake pads will add a certain amount of graphite), graphite is required to have refractoriness of below 1000 ℃. Graphite can serves as both the combustible and refractory material. So, it can be used as a fire-resistant and high-temperature-resisrant material because graphite (lamellar graphite) has a ignition point of at least 3000 degrees in an oxygen free condition. The above information is for reference only and is offered by Xin Ruida Graphite Company.
- Q:The fire prevention board line is made of what material?
- (1) if it's real wood floor, the line should be made of wood. The ready-made wooden line, walnuts, price range depends on the texture width. The common width is 100 mm. One linear meter is around $17 - $30. Paulownia is cheaper with one linear meter more than 10 yuan. When it is composite wood floor, high-density plate modelling line can be used. The price is commonly between 40 to 80 yuan (2400 x 1200 mm), which depends on the thickness and density and also the factory. There are also imitated wooden aluminium line. (3) if it's the marble ground, you would better use marble line, which is 200 yuan one square meter. It's price is also unequal. The imitated stone is also available. There are a lot of kicking decoration materials and it depends on how you use it. That is to say crural line should be coordinate with the ground. It means that it sjould not only to be beautiful but also to be practical. It would be better if it is relatively cheap as well.
- Q:what's the fire endurance of fireproof?panel?
- fire endurance of fireproof?panel generally is 3 hours. For example, 12 mm non-asbestos fiber reinforced calcium silicate board, fireproof?panel, two single 75 keel. through the monitoring of national fireproof construction materials quality supervision center, it's security and refractory time will reach over 3 hours. fireproof?panel, also called fire resistance board, scientific name is thermosetting resin impregnated paper laminated wood,english abbreviation HPL(Decorative High - pressure Laminate) is fire resistant building material for surface decoration and has rich surface colors,lines and special logistics performance, it's widely used in interior decoration, furniture, cabinets, laboratory table, external wall, etc.
- Q:What is refractory?
- Refractory materials are widely used in metallurgy, machinery manufacturing, chemical industry, petroleum, power and other industrial fields. It is an inorganic nonmetallic material mostly used in metallurgical industry with the minimum refractoriness of 1580 ℃, able to resist high temperature without softening (annealing). It accounts for 50% to 60% in total output. Refractoriness refers to refractory's ability to resist fire.
- Q:What are the material requirements of class A fire resistant door ?
- Refractory time should be no less than 1.5 hours.
- Q:What is high alumina refractory?
- High alumina refractory: High alumina refractory products, with high refractoriness, compressive strength and refractoriness under load, it is used for masonry of a variety of large-scale blast furnaces such as steel furnace, air heating furnace and electric furnace, and for high-temperature parts of thermal equipment like rotary?kilns.
- Q:Ask some questions about refractories
- Is a kind of refractory material, jargon called hook materialThe iron runner: a combination of the super high Los resistant technology, aluminum and corundum, silicon carbide and other raw materials, to high-quality composite binders and additives, strict proportioning, elaborate. The utility model has the advantages of good slag resistance, good thermal shock resistance, long service life, convenient use, simple construction, and obvious reduction of labor intensity of workers.Application: it is suitable for blast furnace tapping system.
- Q:What does the function of SiC for refractories?
- As inorganic material, the silicon carbide has the characteristics of high temperature resistance and good anti-wear ability. The sisic products can be used at the blast furnace ceramics. For the unburned?brick, such as alumina-magnesite carbon brick, the silicon carbide can also be added as an antioxidant.
- Q:Can anyone tell me which materials are fire-proof high temperature resistant material?
- Fireproof high temperature resistant material is the synthetic material with fireproofing properties, or the material itself is high temperature resistant, heat-resistant, flame-retardant material. Fireproof materials are mainly used for construction with a variety of forms, which plays an absolute role in modern fire protection. The commonly used fireproof materials including fireproof panels, fire doors, fireproof glass, fire retardant coating and fireproof bag, etc.
