Q:What are grade classifications of the external walls for fireproofing?
The basic level can be divided into: A1, A2, B1, B2, B3 and other levels. There are many technical indicators to make specific division, but I partly cannot report for a while, because it is very professional and technical. Please contact Qingdao Shanfang Instrument Co., LTD for details, they specialized in the external wall thermal insulation materials fire rating testers.
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:How many grades of fire rating are there for interior decoration materials?
It can be divided into construction classification and fire resistance rating. Fire prevention for buildings. Fire prevention measures should be taken in the architectural design to prevent fires and reduce fire hazards to life and property. Building fire protection includes two aspects: fire prevention before fire disaster and measures in fire disaster, among which the former is mainly to confirm the fire resistant rating and fire-resistant structure.
Q:How about the prospect of refractory material?
Area depends the market. Resource-based industry
Q:What's the material of fireproof and wear-resisting floor?
Hello! Fireproof floor is non-flammable, wear resistant, and beautiful. It is made by construction steps and has many advantages: seamless, environment friendly, non-toxic, resistant to abrasion and corrosion, waterproof, dustproof, beautiful in appearance with integriality and no irritating odor The material of fireproof floor is in the form of liquid which will be in the shape of solid membrane after the completion of construction. It can be widely applied to the ground in the factory, residential ground or walls, and large areas like institutions and warehouses with high requirement on fire prevention. It can also be used in the field with no requirement on fire protection for it is beautiful in apperance and just like epoxy floor, and with good cost performance, it is a kind of commonly used decorative material. Hope it's helpful for you!
Q:What are the specifications of refractory kilns ?
There several points need to be noted ① selection of body material. The refractory lining of the front kilneye turns gelid and hot rapidly and frequently, so the temperature is in the range of 800 ℃ ~ 1250 ℃, allowing it to withstand wear of the cement clinker and corrosion of the cement base. The body material of castable refractory must be chosen according to its service conditions, in order to ensure that it is cheap and easy to use. ② the selection of admixture. Shapeless refractory materials are typical in-situ reaction refractories. Therefore choosing admixtures is very important and must ensure workability, baking performance, and excellent material properties. Admixture for Kiln refractory castable includes dispersants, accelerators, plasticizers, sintering agent, bulking agent and antidetonant. Materials of sintering agent are animate clay, zirconite, titanium dioxide and Peng compounds. Such substances produce a certain amount of mullite crystals, zircon phase, titanium aluminate crystal and inconsistent melting compounds (2Al2O3 • B2O3), etc. under the operating temperature and in situ reaction. They are accompanied by volume expansion and microcracks, enabling it to compensate for the sintering shrinkage, so that the casting material can have sintering strength, corrosion resistance and good thermal shock resistance. In summary, the refractory castable material for the rotary kiln shall be determined in accordance with its service conditions. It is recommended that clients should also communicate with technical personnels and sales staff about some facts of the rotary kiln when buying it, so that they can get the satisfying rotary kiln.
Q:Who knows the fire rating of fire partition with steel stud?
Partition system made by fire partition with steel stud and high-quality keel has good fireproofing performance and is non-combustible sheet. Flame burn duration is zero. It does not burn at 800℃, and it is without flame at 1200℃. Its fire resistance rating reaches GB8624-A standard through test, which reaches the highest fireproofing and non-combustible level grade A1. 10MM fire endurance can reach up to 4 hours fire resistance maximum limit. It can absorb a lot of heat during the process of burning and delay the rise of temperature in surrounding environment.
Q:How can refractory materials be divided?
Refractory materials in China can be roughly divided into refractory products and unshaped refractories.
Q:Who knows about the grade C fireproof door materials?
grade C fireproof door materials: 1. the doorframe raw materials of grade C fireproof doors: the galvanized steel sheet is no less than 1.2 mm(the thickness of steel plate is no less than 1.5 mm when the height and width of doors are more than 2.1 m and 1.2 m respectively). 2. the door leaf raw materials of grade C fireproof doors: the thickness of galvanized steel sheets is no less than 0.8 mm. 3. the reinforcement raw materials of grade C fireproof doors: the thick steel plate is no less than 1.2 mm, if there are bolt-holes, the thickness of which is no less than 3.0 mm. 4. filler: The fireproofing filling materials that fit the environmental and standard needs(for instance, door leafs are filled with perlite fireproof materials inside, and doorframes are filled with fire-resistant cement) meet the test criterion promulgated by the relevant state departments. 5, the sealing requirements: there are seal grooves in doorframes and within which are embedded with refractories.
Q:what materials can make external wall fireproofing paint have the fireproofing effect
Adding flame retardant or fire retardant materials can be fireproofing, which commonly referred to as the external walls of fire retardant coating or fire retardant coating. Principle: Fireproof paint itself is flame-retardant or non-combustible, so that the protected base material can not directly contact with the air in order to the ignition delay and reducing the burning speed; except that, it also has a lower thermal conductivity, which can delay the transfer of flame temperature to the protected base material; fireproof paint thermal can decompose non-combustible inert gas by heating to dilute the thermal decomposition of combustible gas in protected object, making it difficult to burn or slow down the speed of burning.
