- Q: What is the fire resistance thickness of the thin fire-retardant coatings?
- There is no detailed requirement on the thickness of the thin steelwork fireproof coatings and the thickness there refers to a certain thickness which must(at least) have fire resistance for a certain time. The thickness of fireproof coatings in engineering generally depends on the manufacturer's test reports. Our thin steelwork fireproof coatings: the fire resistance is 2.5 hours, the thickness is 4.9 mm, the fire resistance is 2.0 hours, the thickness is 3.5 mm, the fire resistance is 1.5 hours, the thickness is 1.75 mm, the fire resistance is 1.0 hours, the thickness is 1.17 mm.
- Q: How long is the fire-fighting time of A class fire resisting window?
- Duration of fire resistance of A class fire resisting window is not less than 1.2 hours; B class window is not less than 0.9 hours. And when install fire window, you must use Level to correct or use hanging line method to correct verticality of four directions, making its same horizontally anf vertically. Window frame must be integrated with the building, using wooden or metal parts connected to the wall. After steel frame is installed, cement mortar must be watered between window frame and wall , and is maintained more than 24 hours before normal use.
- Q: Who knows what is the external wall thermal insulation materials for level A fireproofing?
- external wall thermal insulation materials level A fireproofing: Incombustible building material is a material that does not occur any burning. Class A1: Monomer inorganic non-combustible. Noncombustible means no open fire. Class A2: Non-flammable organic compound is namely composite materials and non-flammable, the amount of smoke must be qualified. Class B1: nonflammable building material: non-flame material has good flame resistance. It is difficult to fire under the condition of open fire in the air or high temperature, and it is not easy to quickly spread, and when the combustion?source is removed, the combustion will stop immediately. Class B2: combustible?building?materials: flame material has a good flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily lead to the spread of fire, such as wooden column, timber roof truss, timber beam and wooden stairs.
- Q: What's the requirements of fire-fighting criteria of heat insulating material?
- Specific provisions go as the following article 8: roof grassroots adopted duration of fire resistance is the non-combustible component that shouldn't less than 1.00 h's. Its roof insulation materials should not be below B2; Otherwise, the combustion performance of insulating material should not be below the B1 level. Article 9: The junction of the roof and wall, the insulation layer around the opening part of roof should use the grade A thermal insulation material to set level fire-fighting belt that width is not less than 500 mm. Article 10: the roof waterproof membrane or flammable insulation layer should adopt incombustible material to cover.
- Q: The classification of fire-resistant material
- Refractory material cna be divided into common and special fire proofing material. Common fire proofing material can be sub-divided in to acid fire proofing material, neutral fire proofing material. and alkaline fire proofing material according to chemical properties. Special fire proofing material can be divided into high temperature oxide refractory, refractory compounds and high temperature composite materials according to the composition. In addition, it also can be divided into common refractory products (1580 ~ 1770 ℃), high-grade refractory products (1770 ~ 1770 ℃) and super refractory products (above 2000 ℃) according to the strength . According to the shape, it can be divided into block (standard brick, special-shaped brick, etc.), special shape (crucible, sagger, pipe, etc.), fibrous (aluminum silicate, zirconia and boron carbide, etc.) and irregular shape (refractory clay, refractory castable, ramming material and so on). According to sintering process, it can be divided into sintered product, fused cast product and melting jetting product.
- Q: What effect does aluminium powder play in refractory bricks?
- Aluminum powder is the main temperature resistant material ~ ~ ~ ~!
- Q: How is the performance of refractory materials?
- It is a little difficult to answer. There are some requirement for refractory materials, such as fire resistance, softness, creep, thermal shock, abrasive resistance. Besides, requirements for construction performance include: Liquidity, plasticity and other linear change rate, volume density, strength (including high temperature) and all other important indicators must be tested the same conditions with the use of test conditions and test items like body density, strength, line changes in the basic project
- Q: What do refractory materials include?
- What refractories are included? Refractories include AZS brick, corundum brick, direct-bonded?magnesia-chrome, carborundum brick, silicon nitride bonded silicon carbide brick, non-oxide refractory materials such as nitride, silicides, sulfides, borides and carbides, oxidation calcium, chromium oxide, aluminum oxide, magnesium oxide and beryllium oxide.
- Q: How many types of fire-resistant material?
- 1. Acid fire-resistant material refers to one with more than 93% SiO2. It is featured by resistance to the corrosion of acidic slag ad high temperature and easy to react with alkaline molten slag. 2. Alkaline refractory material generally refers to one with magnesium oxide or magnesium oxide and calcium oxide as the main component. It has high refractoriness and strong resistance to basic slag. 3. Silicate aluminum refractory material refers to one with SiO2, Al2O3 as the main component. According to the content of Al2O, it can be divided into three categories: half siliceous (15-30% Al2O3), clay (Al2O3 30 ~ 48%), high aluminum (more than 48% of Al2O3). 4. Fused cast refractory material refers to shaped refractory products made by high temperature melting and casting.
- Q: What is the the best ratio of mortar in refractory cement?
- The ratio of refractory cement are: M10 the ratio of cement and mortar: cement: Sand= 346kg: 1631kg M7.5 ratio of cement and mortar: cement: Sand =274kg: 1631kg M5 The mix proportion of cement and mortar: cement: Sand = 209kg: 1631kg M10 mix proportion of composite mortar: cement: Sand: Lime =306kg: 1600kg: 29kg M7.5 mix proportion of composite mortar: cement: Sand: Lime =216kg: 1600kg: 64kg M5 The mix proportion of composite mortar: cement: Sand: Lime =205kg: 1600kg: 100kg
