Q:How long is the fire-fighting time of A class fire resisting window?
Duration of fire resistance of fire resisting window: A class window is not less than 1.2 hours; B class window is not less than 0.9 hours and C class window is not less than 0.6 hours. Technical Requirements: 1materials and accessories (1) window frame structure adopts stell framework and wooden framework that have a certain strength to ensure integrity and stability. (2) steel framework and batten can choose galvanized steel plate or stainless steel The selection criteria meet requirements of GB12955 steel fire door general technical conditions in the provisions of article 5.1. The selection criteria of wooden framework and batten meet requirements of GB14101 wooden fire door general technical conditions in the provisions of article 5.1.1. Filling material of steel and wooden framework shouldn't adopt non-combustibility material. (5) fire-fighting glass can adopt testing-qualified product that don't influence fire resistance performance of fire resisting window. Light transmittance of glass is not less than 75% of the same layer common plate glass. (6) Sealing material between framework and fire-fighting glass should adopt Flame retardant material which can serve as fire-fighting and smoke-resistant when encounter fire disaster. (7) hardware fitting should accessories product that is tested to be qualified. 二. installation requirement: 1. When Party A takes over goods, he should check numbers, specification, grades and whether Accessories are Conformed and complete according to contract.
Q:what is the Specifications Grading for Fireproof rubber insulation materials ?
External insulation materials, welded wire mesh matt external wall insulation, external wall thermal insulation mesh matt. 1,inorganic activel thermal insulation materials 2,silicate thermal insulation material 3,ceramic thermal insulation 4, gelatine powder polyphenyl granule, 5,teel wire gauze picking cement cystosepiment(Estazolam platepowder particles)6 extruded sheetXPX. 7,Rigid polyurethane coating at the scene, Polyurethane insulation board8,rigid polyurethane foam,9EPS foam board roofing materials. 1, a ceramic insulation board 2, xps extrusion board 3, perlite and perlite brick 4, vermiculite and vermiculite brick heating, air conditioning Material: Phenolic resins, polyurethane waterproof thermal insulation integration, sponge rubber, polyethylene, polystyrene foam, glass wool, rock wool Steel material: Polystyrene, extruded sheet, polyurethane panels, glass wool carpets and the like. Five inorganic thermal insulation materials: Foam cement, DY inorganic active insulation system super thin vacuum insulated panel for building external walls .
Q:What refractories are accessible with ease in daily life? This material is suitable as a disposable mold and crucible for melting brass.
There are many refractories in daily life. Such as the lining of furnace! And refractory cotton ... If you want to melt brass, you need to resort to professionals! It's rare in daily life to find out those molds that can be made by ourselves. You can buy a corundum crucible in the neighbouring laboratory equipment market! Remember that brasses' melting point is at above1000 degrees, so the material must have refractoriess of 1000 degrees.
Q:How long is the fire resistant limit for ultra thin fire retardant coating?
There is no detailed stipulation for ultra-thin fire retardant coating, and the thickness of the inside is the fire resistance limit shall reach certain time(at least). In engineering, the thickness of the fire retardant coating is generally determined according to the manufacturer's testing report. We use thin fire retardant coating for steel structure: if the fireproof limit is 2.5 hours. the thickness should be 4.9mm. If fire-resistant limit is 2 hours, the thickness shall be 3.5mm. If the refractory limit is 1.5 hours, the thickness shall be 1.75mm. If the limit is 1.0, the thickness is 1.17mm hope my answer can help you
Q:Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?
Strictly speaking, as long as there are solid wood packaging, you need to do fumigation inspection, proved not necessarily used, there are IPPC chapters on it.
Q:What refractories can withstand high temperature above 2100 degrees?
But the price is more expensive, while the insulation performance is not as good as common materials. Is there a material that can withstand 2100 ℃? Currently, the long-term use temperature of the best refractory bricks is about at 1800 ℃, while materilas that can withstand a temperature of 2100 ℃ are relatively rare in the production.
Q:Which refractory material is better in China? Industrial furnace, mainly in non-ferrous industries, glass kiln, cement kiln business.
Such solid nano microporous insulation material with nano inorganic refractory powder special, with a huge surface area, nano particles contact between the minimum point contact point contact thermal resistance is very large, the heat conduction effect of the material becomes very small, resulting in heat conduction coefficient of solid such nano porous insulation materials very small; nano pores formed of nanoparticles, the average size of 20 nm, and the average free path of molecular thermal motion at room temperature under static air is 60 nm, thus locking the air molecules in powder within nano pores, making the micro convection heat transfer effect between the stationary air molecules disappeared. The room temperature thermal conductivity of solid such nano microporous insulation material is lower than the static air; at high temperature, the main effect of heat transfer heat radiation, Good energy-saving insulation materials with nano microporous infrared additive special, stop at a high temperature and reflected infrared radiation, reduce the heat radiation effect to the lowest point, the radiation heat transfer coefficient of materials under high temperature is reduced to the lowest value.
Q:What are the commonly used admixture for alumina-magnesia refractory? What are the impacts on its performance?
Sodium silicate, pure calcium aluminate cement, boric acid
Q:How long usually will the A-level fireproof materials prevent the flame?
Having a fire resistance test on any building components -----according to the standard time-temperature curve. This period starts from the time when affected by fire and ends up with losing the ability to support or to insulate fire or the integrity of the components. It can be expressed in hours. A-level fireproof materials can last for 2 hours.
Q:The following statement is correct: artificial corundum has a high melting point and can be used as a high grade refractory material. The main component is silica dioxide
1. corundum is the main component of alumina. 2. agate is the main component of silica. 3. is right. 4. glass is silicate. 5. solar cells are made from monocrystalline silicon. So 3.5 correct, choose D.
