Q: What are some of the new refractories and what are their characteristics?: Alumina, a better refractory material, is a new type of ceramic refractory, the characteristics are unclear.

Q: I know which material is the fire resistance rolling shutter door: Fire resistance rolling shutter door and ordinary roller shutter are basically same, the differences are: Its inner and outer sides are generally made of galvanized iron sheet, filling asbestos fireproofing material betwwen two layers of fire resistance rolling shutter door, and some fire shutter doors can be interlocked with the relevant fire control system, when the breaking out of fire , it can automatically "half-drop" and "full drop".

Q: What's the function of aluminium dihydrogen phosphate on the refractories?: Mainly used for binder of high-temperature furnace refractory. Characteristics of liquid aluminum dihydrogen phosphate, castable. solid used for refractory spraying coating, chamotte, ceramic construction, which has high break resistance after being dried in 350-500 ° C, phosphate bricks. Characteristics of the solid aluminum dihydrogen phosphate, binding agent used for castable and casting industry: together with the refractory aggregate, ramming mixes at room temperature: Easy to mix, crush resistance, hydration resistance, chamotte, will not become soft even if soaked or boiling in water, molding. Liquid use refractory spraying coating, mainly used for corundum, chrome corundum water gap in refractory industry. The production of chrome aluminum zirconium corundum brick for water-coal-slurry gasifier is especially suitable for site construction applications mainly used for the electrical industry, high-temperature kiln and furnace, hardener, after mixing between 90-110 ° C for 4-24 hours at a constant temperature, forming strong bonding strength, electrical insulation, heat treatment resistance furnace

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 type of firebrick does TZ-3 represent?: Height is 65mm, length is 230mm, and width is 114mm, that is the t-3 firebricks which meet the national standard.

Q: What is the concept of lightweight refractory material?: Lightweight refractory material has high porosity, mechanical strength and erosion resistance. Compared with normal refractory bricks, it is a kind of refractory material with large volume shrinkage in high temperature, low thermal conductivity and small bulk density. It is used as thermal insulation material in industrial furnace and other thermal equipments. It has poor wear resistancel.

Q: Does anyone know which materials belong to light fire resistant material?: Building board of lightweight fireproof partition material: 1, GRC lightweight partition material glass fiber reinforced concrete; it is a kind of fiber cement composite with alkali-resistant glass fiber as reinforced material and cement mortar as the base material . Aerated concrete block equipment foundation construction Its outstanding features are having good tensile, rapture strength and good toughness. This kind of material is particularly suitable for the production of ornament mould and the manifestation of strong texture. Compared with these external wall decorative materials, the biggest advantage of GRC material is to meet the individual needs of architects, completing the expression of various ornament moulds and skin textures. 2, fiber reinforced low alkalinity cement building plate. The standards stipulate the classification, raw materials, technical requirements, test methods, inspection rules, packaging, labeling, transport and storage of the fiber reinforced low alkalinity cement building plate.

Q: The principle of choosing fire-resistant material in Thermal Energy and Power Engineering equipment.: Different thermal technology equipment has different operation condition and select different refractory material. We should take economical and practical as principle.

Q: which is better as household fireproof material ?: the thickness recommended is 1mm or more # 304 stainless steel plate, refractory corrosion-resistant, easy to clean. It now appears that among the most common fireproof material, asbestos is the best. But the asbestos harmful effect is also great, especially for lung damage. Now on the market, the polyurethane, polystyrene, rock wool glass wool, phephenolic aldehyde fireproofingthermal insulation board. But now the phenolic aldehyde fireproofing thermal insulation board has superior performance! phenolic aldehyde containing only carbon, hydrogen and oxygen atoms, when subjected to pyrolysis, except small amounts of CO gas, the other will not produce toxic gases, maximum smoke density is 5.0%.

Q: Who knows what fire heat preservation material are there?: It can be realized through inorganic insulation materials, such as glass wool, rock wool, foam glass etc.. The phenolic foam materials inside organic foam material is more special. Phenolic foam does not only have a good thermal insulation performance, but also can be combined with steel and other materials, to achieve a class A fire retardant level. Class A thermal insulation include: Rock (ore) cotton, foam glass, inorganic thermal insulation mortar, etc.. 1 thermal insulation materials with class A combustion performance Phenol, powder polystyrene particles etc.. Fire insulation materials of fire barrier zone can use class A material with class A combustion performance in rock (ore) cotton, foam glass, inorganic thermal insulation mortar.
