$Insulation Low Cement Refractory Castable For Rotary Kiln$

Q: How long is the duration of fire resistance of autoclaved flyash-lime bricks?: The compressive strength of the autoclaved flyash-lime bricks is generally higher, which can reach 20MPa or 15MPa, at least 10MPa, and it can withstand the 15 freeze-thaw cycles. Besides,fly ash brick is a kind of potential active hydraulic material. In the humid environment, it can continue to produce hydration reaction and make the internal structure of the brick is more dense, which is conducive to improvement of the strength. It is found in experiments and many investigations that sample some carbide which is used for foundation, plinth and drains, after one or twenty years of freezing thawing and wetting drying, some bricks have been completely carbonized, but strength is not reduced, increased instead. This is one of the merit of autoclaved flyash-lime bricks.

Q: How many kinds of fireproof materials are there in the market?: Inorganic insulation materials basically can achieve the goal, such as glass wool, rock wool, and foam glass. The phenolic foam in the organic foam material is special. Phenolic foam is not only good at insulation, but also good at compounding with steel and other materials to achieve A-level performance, and the A-level insulation materials are: rock(ore) wool, foam glass and inorganic thermal insulation mortar. Insulation materials with B1 combustibility mainly are: Phenolics, polystyrene granules, etc. The insulation materials of fire barrier zone can use such A-level materials as rock (ore) wool, foam glass, and inorganic thermal insulation mortar, etc.

Q: What characteristics do A grade external wall fireproofing material have?: 1. Save space and reduce costs; 2. Fireproofing, green and environmental protection; 3. Waterproofing; 4. Sound insulation; 5. Thermal insulation; 6. Install easily and shorten the construction period; 7. High safety performance.

Q: The effect of a high content of water in liquid resin exerted on refractory material?: For one thing, Substandard whiteness, transportation, low quality and the storage of refractory material may account for this. For another, a high content of moisture reduced the performance of refractory material. A high content of moisture is equal to buy water with same money in terms of trade settlement. Based on this, we can’t consider the super-standard water content from a single aspect, because the water content in refractory material is definitely super-standard, and another problem is particle size. Many people hold the idea that excessive amount of water content may revive its original performance, but it tends to have influenced the quality of refractory material.

Q: How to count the construction costs of refractories?: In winter, the temperature of the the fire-resistant masonry, fire-resistant plastic, sodium silicate, phosphoric?acid castable should be maintained above 5 ℃. Usually greenhouses in which heating facilities are installed to maintain the appropriate temperaturere for the construction environment should be erected in refractory masonry. The temperature around the construction site of the industrial furnace and refractory masonry shall not be lower than 5 ℃.

Q: What are fireproofing materials?: Class A incombustible material: Granites, marbles, terrazzos, cement products, concrete products, plasterboards, clay products, glass, tiles, mosaics, steel, aluminum, copper alloys; B1 class flame nonflammable materials: Ceiling materials: gypsum plaster boards, fibrous plasters, cement particle boards, mineral wool decorative acoustic panels, glass wool decorative acoustic boards, perlite decorative acoustic boards, flame retardant plywoods and medium density fiberboards, rock wool decorative panels, flame retardant woods, aluminum foil composite materials, flame retardant phenolic laminates, aluminum foil glass fiber reinforced plastic composite materials; Wall covering: gypsum plaster boards, fibrous plasters, cement particle boards, mineral wool boards, glass wool boards, perlite boards, flame retardant plywoods, flame retardant medium density fiberboards, fireproof plastic decorative plates, nonflammable double-sided particle boards, multicolor paints, nonflammable wallpaper and textile wall cloth, flame retardant simulated granite decorative plates, magnesium oxychloride cement prefabricated wall panels, flame retardant glass fiber reinforced plastic plates, PVC plastic clapboards, high-strength and lightweight composite wallboards, fire-retardant molded wood composite boards, flame retardant colored artificial boards, nonflammable glass fiber reinforced plastics, etc.

Q: What crusher is used for raw material of broken refractory material? What is the rough crushing process? What are the materials? Thank you!: Now cone crusher is generally used.

Q: What does refractory mean?: Basic refractory material generally refers to Magnesium Oxide or Magnesium Oxide and calcium oxide as the main component of refractory materials. This kind of refractory material has higher refractoriness and strong resistance to alkaline slag.

Q: Which refractory is better for building 1500 degree kiln ?: The top and wall use alumina hollow ball brick. If it is cubic kiln, the kiln bottom should use heavy corundum brick. If it is continuous kiln, burning zone should use alumina hollow ball brick, burning zone seal and kiln car face brick. If it is pit furnace, curved seal should use heavy corundum brick, and furnace wall and top should use alumina hollow ball brick. That depends on what kind of kiln it is. Curved seal and kiln car should use heavy corundum brick. You can add me friends to have further talks.
