Q:How should fireproof building materials be ranked?
Division of fire-proof grade of buildings is one of the most basic measures in the fire-fighting technology and measures of buildings. According to our national code of building design, fire-proof grade of buildings are classified into four levels of first, second, third and fourth, of which the first level is the highest in fire resistance and the fourth level is lowest in fire resistance. Fire resistance rating of buildings depends on the combustion performance and fire endurance of the building component. The so-called building component refers to the walls, foundations, beams, pillars, floors, stairs, ceilings, etc.
Q:What are the physical properties of refractory material?
The mechanical properties of refractory material include compressive strength, volume density and sclerosing, slag resistance, elastic modulus, thermal shock resistance, oxidation resistance, bibulous rate, fluidity, resilience, bond strength and slump, electrical conductivity, specific heat, heat capacity, the impact strength, linear change, torsional strength, stomatal aperture distribution, resistance to acid, etc. The use performance of refractory material include refractoriness, thermal emissivity, condensation, porosity, coefficient of thermal expansion. Thermal properties of refractory material include thermal conductivity, temperature conductivity, plasticity, the hydration resistance, creep performance. The physical properties of the refractory materials include structure performance, mechanical properties, shear strength, load softening temperature, CO erosion resistance. The structure properties of the refractory materials include porosity, alkali resistance and sintering. The operating performance of refractory material include consistency, tensile strength, the use performance and operating performance, wear resistance, bending strength, thermal properties.
Q:Which are fireproofing external wall materials?
According to combustion performance, external wall thermal insulation materials are classified as Grade-A and Grade-B. Grade-A refers to incombustible material and Grade-B combustible material. A few years ago the fire in CCTV building and Shenyang Hotel were caused by Grade-B material. Currently Grade-A material is more commonly uesd and less expensive than Grade-B material. Grade-A material can be divided into thermal mortar, phenolic foam board, rock wool board, foam cement board, etc. Thermal mortar is easy for construction and unexpensive, but it is also easy for faking due tou its simple procesing. It is recommended to find a large factory whihc has gone through the formalities.
Q:What are the raw materials of refractory concrete ?
Q:What are the specifications of fire resistant bag?
Currently there are four specifications: C10, C40, B40 and B50 suitable for steel ladle of less than 60 tons. I hope it can help you.
Q:What are the advantages and disadvantages of new external wall fireproof and thermal inuslation matertials?
Advantages: 1)Low requirements on the waterproof, weather resistance and other technical indicators. The dry wall and gypsum plastering mortar, etc. can meet the requirements and can be easily obtained; 2) The inner insulation material are separated by the floor, and construct within a height of only a storey , without erecting scaffold ; 3) In the hot summer and cold winter or hot summer and warm winter area, the inner insulation meets the requirements; 4) The glass beads overcome the shortcomings of expanded perlite, like, large amount water absorption, easy powdering, big volumetric shrinkage in the slurry mixing process, easily leading to post-insulation product performance degradation and hollowing, cracking, and also make up for the defects of polystyrene particles organic materials, like, flammable, poor fire performance, producing harmful gas at high temperatures and anti-aging, poor weather resistance, poor workability and large rebound in construction, ect. Disadvantages of external wall insulation : 1) Since the ring beam, slab and column structure would cause thermal bridges, leading a greater heat loss; 2) It is of low intensity, high water absorption, easy to shrink and crack. The insulation system is prone to cracking, leaking or loss and other common quality problems, especially it is easy to crack at the seams, thus being difficult to exsit as long as the building. 3) It is inconvenient for the users to redecorate and hang ornaments; 4) It takes up indoor used space;
Q:What defect does fused cast refractories have ?
The impact on the quality of glass is mainly the defects that eroded down refractory materials mixed in the glass, thus being prodeced of grass products. Defects are mainly foreign body defects such as sand, knot and wave reinforcement.
Q:Which refractory quality inspection authority is good?
Of course, it is Research Institue of Refractory Materials in Luoyang, Henan. In fact, what we want is accuracy and authority. Quality and inspection costs, which is more important?
Q:Who knows what kind of fire prevention materials are there?
1, Fire-proof board Fire-proof board is the most frequently used materials in the market. There are two kinds of fireproof boards which are commonly used; one is the high pressure decorative board, which has the advantages of fire prevention, damp proof, abrasion resistance, oil resistance, easy cleaning, and more variety of colors and designs. The other one is a glass magnesium fire board, the outer layer of which is a decorative material, the inner layer of which is a mineral glass magnesium fire material. It can resist 1500-degrees high temperature, but not suit for decoration. The installation of fireproof ceiling in the exit passageway, stair well and corridor can ensure safety evacuation, and protect people from the spread of the fire. 2 Fire-proof door Fireproof door is divided into wooden fire proof door, steel fire proof door and stainless steel fire proof door. Usually the fire proof door is used for the opening of the firewall, the entrance to the staircase, the evacuation of the aisle, the openings of the pipeline and other parts of the building, and it has an important role in fire separation and reducing the loss from fire. 2 Fire resisting shutter I hope it may be helpful to you.
Q:Why do magnesium oxide refractory bricks can be made into refractories?
Nature: It is loose white powder and tasteless. When exposed to the air, it is easy to absorb moisture and carbon dioxide. It is dissolved in acid and ammonium salt and insoluble in water and ethanol, with the melting point of 2800 and the boiling point of 3600. The magnesium oxide has high fire-resistance insulation properties, with high melting point . It can be said to be non-combustible materials.
