fused magnesite

Q:What's the organzational structure of refractory material?: Ingredients (harmful); phase composition. The main components of refractory material include chemical composition and phase composition. The addtional components include main crystal phase, matrix, crystal phase, chemical composition

Q:What are the materials of class A fire resistant window?: Fixed class A fire resistant window should be made up of steel frame, steel casement, and fireproof glass. Fire windows, made up of steel frame, steel casement, and fireproof glass, refers to window that isolate and stop the fire from spreading. Fire window is named according to the main materials of the frame and casement. Window frame is made up of steel and casement wood, vise versa. I hope it is useful.

Q:Manganese steel belongs to refractories: NO!

Q:What is the new fireproofing standard of external wall thermal insulation materials?: The new national standard "Fireproof? Specification of Building Design" (GB50016-2014) has been issued, it will be carried out from May 1, 2015. Compared with "Fireproof? Specification of Building Design" GB 50016-2006 and "fire?safety?rules of tall buildings design" GB 50045-95 (2005 edition), the major changes of new standard is the following: 1. It has combined with "Fireproof? Specification of Building Design" and "Fireproof? Specification of Tall Buildings Design", and has adjusted incompatible requirements between two standards, and has unified the classification of residential buildings in accordance with the building height; 2. It has increased two chapters including the fire-fighting rescue facilities and wooden structures, and has improved the requirements for fire fighting and rescue, and standardized the fireproofing requirements of wood construction; 3. Additional requirements for the fireproofing requirements of building external insulation system; 4. The fire-fighting equipment is written in a separate chapter and improve relevant contents; cancel the design requirements of fire water supply system and smoke control system, and they are regulated by the relevant national standards; 5. appropriate increase in the high-rise residential buildings and fireproofing technical requirements for high-rise civil building whose height is greater than 100m; 6. add the fireproofing requirements used by covered pedestrian during evacuation; adjust and add designers density of construction materials, furniture, lighting shops and exhibition hall; 7. add the fireproofing requirements of underground warehouses, logistics buildings, large combustible gas tank (zone), ammonia storage tanks, LNG storage tank, and adjust the fire?separation distance of liquid oxygen tank; 8. improve the relevant requirements to prevent vertical or horizontal spread of building fire.

Q:What is the most reasonable drying heating curve of magnesia refractories? Products of less than 0.5T: You'd better oxidize magnesia preformed unit at room temperature for a longer period of time, then bake it, during which, it's enough to control the maximum temperature within 300 degrees. During the middle process, usually heating up for 4 hours and keep warm for 3 hours. The entire heating up process takes about 20 hours. If it is the site operation magnesia-based castable, it should be heated slowly in the early stage, and pay attention to keeping warm at 80 degrees Celsius. Every manufacturers has their own heating curves, so do not blindly adopt existing curves, try to make your own heating curve.

Q:What is the main material of fireproof wooden door?: Fireproof wooden door has a lot of materials! including imported timber decorative effects: utilizing the diversity and easiness to cut of the timber, with all the decorative characteristics of the timber. Material selection features, door frames: Using high-quality hardwood, such as imported miscellaneous wood, camphorwood, lauan, hemlock, etc., insetting fire and smoke proof adhesive tape

Q:The development prospect of fire-resistant material: I also want to know, who can say, thanks all the way.

Q:What kind of material is refractory fiber?: Refractory fiber, also known as ceramic fiber, is a fibrous thermal insulation refractory. It has the characteristics of ordinary fibers, such as softness, flexibility, having a certain tensile strength. And it can be further processed into a variety of products such as paper, wire, rope, tape, blankets and felts. Besides, it has high temperature resistance and corrosion resistance which ordinary fibers don't have. As a fire retardant and thermal insulated material, it has been widely used in metallurgy, chemical, machinery, building materials, shipbuilding, aviation, aerospace and other industrial sectors.

Q:what is the material of fixed first rate fire resistant window?: Window frames and fireproofing glass, fire sealing strip, fireproofing glass mound layer, which is infexible fan, and the flexible fans have to plus folding and closing window cleaner. (3) window frames must be integral with the building, using wood or iron to connect the wall. After the installation of the steel frame, the cement mortar must be watered between the window frame and the wall, and it should conserve more than 24 hours before normal use.

Q:What kind of materials can be tested their electrical resistivity in the current refractory industry?: Graphite, Magnesium Oxide, and alumina are all feasible.

We has been adhering to scientific and technological innovation as the company development ideas, establishing the export-oriented development strategy and has close technical cooperation with scientific research institutions.We supply many kinds of calcined bauxite.
