- Q: Are fire materials poisonous after burning?
- High temperature oxide materials in refractory special applications, such as aluminum oxide, lanthanum oxide, beryllium oxide, calcium oxide, zirconium oxide, refractory compounds, such as carbides, nitrides, borides, silicides and sulfides; high temperature composite materials, including metal ceramics, high temperature inorganic coatings and fiber reinforced ceramics.
- Q: What's the fireproof specification for constrcution external wall thermal insulation materials?
- incombustible material: Class A1 (homogenous): such as YT inorganic active insulation material for wall thermal, foam glass, rock(ORE) wool, glass wool, insulation?board of aerogel,expanded perlite series, expaned glazed hollow bead, foam insulation boards, ETC. Class A2 (non-homogeneous composite): such as phenolic foam, gelatine powder polyphenyl granule thermal insulation material, inorganic coating materials and other nonflammable material. phenolic foam insulation board, urea resin foam and board, high flame-retardant polyurethane rigid foam and board, high flame retardant polystyrene cystosepiment, gelatine powder polyphenyl granule heat insulating slurry and other combustible?materials. Requirements for combustion levels of common antiflaming EPS, common inflaming retarding XPS, common antiflaming rigid PU foam board: Class A is incombustible?material (product); B1 nonflammable material (product); B2 combustible?material (product); B3 combustible material (product).
- Q: The primary problem, does the gas permeable brick is fired refractory bricks(refractory) ?
- gas permeable brick have two types:built-in type and external mounted type. the built-in gas permeable brick and the external mounted gas permeable brick are usually made by fire burning, and small part of bricks are made by the low temperature heat.
- Q: which kind of material should be used in fireproofing cabinet?
- Natural stone,marble. advantage: Colorful, soft texure, natural and diverse texture, easy to cut or engraving molding. Disadvantages: Because it is a natural formation, tiny loose crackle is easily folded, because the stone is porous material structure, if sewage and waste water permeate in the structure in the process of production, transportation or construction, it's difficult to clean and easy to crack. In daily cleaning, it is inevitable that there will be some residue left, and dirt is filled into crack under the wiping of rag and becomes a breeding ground for bacteria. 2, granite. advantages: Granite has big density and high hardness, with wear-resistant surface, it's one of the most common materials for family decoration. Compared with natural marble, it can be used in the materials of kitchen countertops, and granite has good anti-bacterial regeneration ability. Disadvantages: As the cabinet table material, natural stone is usually not very long, so in order to produce a long overall table (especially U-shaped, L-type table), it will certainly exist joints, which are also easy to hide dirt. 3, artificial stone. advantages: Artificial stone has richful lines and colors, and it can be comparable to stone, it's non-toxic, non-radioactive, easy to clean, and can be truly seamless splicing. it belongs to economic environmentally friendly material. Disadvantages: Artificial stone belongs to the processing industry, and has low technology requirements, The inferior products of many small companys are fulled in the market and damage customers' interests. There exist faded color,poor aging resistance,oil stain and other issues in affordable products.
- Q: What refractories have good mechanical property resistance and heat expansion and cold contraction property?
- Explain that where you use it for and what requirements you have. Follow-up: I use it in metallurgical furnaces with the features of strong stirring and acidic residue.
- Q: How to classify the grade of wall fireproof and thermal inuslation matertial?
- External wall thermal insulation materials are mainly divided into grade A, grade B1, grade B2 and grade B3. In accordance with the current "Combustion Performance Classification Method of Building Materials", grade A thermal insulation material is incombustible?material and belongs to inorganic heat preservation material. However, grade A thermal insulation material is few in terms of the current market. There are only JETCO YT inorganic active wall thermal insulation material, glass wool, rock wool board, foam glass, vitrified micro bead and grade A fireproofing thermal insulation board. However, compared with grade A thermal insulation material, the more welcomed by the market is the organic insulation materials. Thermal insulation material that is determined as grade B is divided into three levels. Grade B1 is grade is flame retardant. Grade B2 is combustible. Grade B3 is flammable.
- Q: Which kind of furnace hearth refractory is better?
- hearth selected material] hearth material must be durable, high temperature resistant, general selecting masnory made of refractory cement, silicon carbide refractory products, mullite or multicrystal mullite (which is the general term of minerals composed of a series of aluminum silicate, mullite is only stable binary compound in the Al2O3-SiO2 system) etc.. [hearth] is a three-dimensional space surrounded by furnace walls for combustion of the fuel. The funtion of hearth is to ensure the fuel to burn as far as possible, and to cool the gas temperature of the hearth exit to the allowed temperature of convection heating surface safe operation . Therefore, the hearth should have sufficient space and adequate heating surface. In addition, there should be reasonable shape and size in order to fit the burner and the organize aerodynamic field inside the furnace to prevent the flame from adherence, dashing walls and have high fullness and eve wall thermal load.
- Q: What are the advantages and disadvantages of new external wall fireproof and thermal inuslation matertials?
- The new external wall fireproof and thermal inuslation matertials have both the advantages and disadvantages. 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 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.
