Q:What are the materials of white firebricks?
They are made of baked refractory materials with pale yellow and a little brown on the surface and very cheap. They are mainly used to pile up smelting furnace and can withstand high temperature from 580 degrees Celsius to 770 degrees Celsius. While the firebricks, also called refractory bricks by others, have a certain size and shape. They can be classified according to manufacturing process, namely, the unburned bricks, burnt bricks and electrically fused bricks. Also they can be divided into common bricks, standard bricks and specific bricks according to different size and shape.
Q:Which fireproofing materials factory is the best in Xiangyang?
Xiangyang Tianhua Fireproof Materials Co., Ltd. has a variety of products with complete specifications. The products include fireproof cable tray, fire resistant groove, fire-resistant shield, ATD-AB, organic fire-proof caulking, intumescent fireproof pillow, fire retardant module, cable refractory coating, ultra-thin fireproof coatings for steel structure and other products. All products have passed the relevant tests and inspections, all performance indexes are in full compliance with national or industrial standards, and meet the technical requirements of cable fireproofing. Xiangyang Weicheng Fireproof Materials Co., Ltd. is specialized in research and development of fire-fighting apparatus and fire retardant materials! It's main products: fireproof bag, asbeston, fireproofing mud, and other types of fireproofing materials.
Q:Who knows what material is in the center of fireproof rolling curtain?
Material and the type high silica cloth as curtain, side rails, with galvanized steel in its end and stainless steel two kinds of materials with double curtain in the end I hope my answer can help to you
Q:How to divide the fire rating standards of insulation materials?
The fire rating classification standards of insulation materials, 1. Insulation materials with A-level combustion performance: inorganic fiber spraying, rock wool, glass wool, foam glass, ceramic foam, foam cement, close-celled perlite, etc. 2. Insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), Phenolics, Polystyrene rubber powder particles,etc. 3. Insulation materials with B2-level combustion performance: Expanded polystyrene sheets(EPS), Extruded polystyrene board(XPS), Polyurethane(PU), Polyethylene(PE), etc.
Q:What things and cement mixed can act as refractory?
This has a lot. I suggest you can check monolithic refractories.
Q:A chemical problem with refractory materials
Not necessarily. What you mean is silicate
Q:which kind of material is chosen for fireproofing window?
Firstly, fireproofing window glass must be tempered, ordinary glass won't play a role of fireproofing, and fireproofing window fan is fixed, can't be open, if you can open it, it won't play a role of fireproofing. And you can ask the property to provide texture report of fireproofing windows, fireproof material stipulated by our national fire protection laws and regulations must have fireproofing inspection reports, there must be. and fire window glass should have a fireproofing sign. The main role of fireproofing window is to isolate the fire, and play a role of fireproofing and escaping, avoid the fire quickly spread in.
Q:How is refractory material made?
It is made from yellow mud and water.
Q:How to do environmental impact assessment for refractory Co., Ltd.
The preparation of a report or statement. During the compilation process, any problems should be actively communicated with the construction side. For example, dust collector selection, environmental protection investment, total emission approval. (especially the total emission, you must let the construction side and communicate with the environmental protection bureau to get the total amount, otherwise you write the EIA does not make any sense.) Generally speaking, the preparation of the report is longer, about forty days; and the preparation of the report table is shorter, about fifteen days.
Q:What are some of the new refractories and what are their characteristics?
Refractory common AZS refractories are often used brick, corundum brick, magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, aluminum oxide, beryllium oxide and other refractory materials, Magnesium Oxide
