Q:How to make the service life of refractory materials longer?
Take acid resistant refractory materials as example: the atmosphere should be acidic atmosphere, if used in an environment whose temperature is 1900℃, it would exacerbate the loss of refractory materials, so don’t use overloaded. Second, select the appropriate refractory materials according to the environment. For example, if its operating temperature is 1800℃, generally speaking, the normal use of it according to the instruction of refractory materials would be fine.
Q:who knows the uses of refratories?
Of course, the role of the refractory material is fireproof, generally used in large buildings. It can reduce casualties and economic losses caused by the fire. it also can be used on the chemical instruments. ! !
Q:What's the definition of fire endurance of the fire-resistant coating for steel structure?
Fire endurance (h): Under the condition of standard fire resistance test, the time when the building components, accessories, or structure is subjected to fire to the time when they loose stability, integrality or thermal insulation is called fire endurance which is showed in time. Steel is the kind of building material that is nonflammable with many properties of seismic resistance and bending resistance. In practical applications, steel can improve the load capacity of buildings in a relative way, meet the needs of buildings design, beauty and mould, and it can also avoid the defects of poor flexibility and tensile strength of buliding materials like concrete. Therefore, steel is quite popular in the construction industry, and it is widely used in single-story or multi-storey skyscrapers, plants, warehouses, waiting rooms and airport terminals, etc. However, as a kind of building material, it has some unavoidable defects in fire prevention. That is its mechanical properties like yield point, tensil strength and elasticity modulus will decrease dramatically with the rise of the temperature.
Q:Does refractory belong to metallurgical auxiliary materials?
Refractory includes metallurgical auxiliary materials.
Q:what's the fire endurance of fireproof panel?
non-asbestos calcium silicate board, fireproof panel partition will excced over 4 hours, two single 75 keel. 12 mm fireproofing calcium silicate board partition, through the monitoring of national fireproof construction materials quality supervision center, it's security and refractory time will reach over 4 hours.
Q:What kinds of refractory will be used in kiln of sintering ceramics?
High alumina brick, clay brick, insulating brick and silicon carbide plate.
Q:What are included in wall fireproofing material?
Wall fireproofing materials include dry wall and gypsum block. Dry wall is made into board material through process by using building plaster as main material, adding an appropriate amount of additive and fiber to make board core and using tailor-made board paper as protection surface. Dry wall ia characterized by light weight, sound insulation, heat insulation, strong processing performance and easy construction method. Gupsum block is lightweight building plaster product made by using building plaster as main raw material, adding water, stirring, moulding by casting and drying. Fiber reinforced material or lightweight aggregate are allowed to add during the production and foaming agent can also be added. It is soundproof, fireproof, convenient to construct and many other advantages. It is a kind of new wall material with low carbon, environmental protection, health and in line with the development requirements of the times.
Q:How many levels are there in the classification of PP fireproof materials?
PP fireproof materials level V-0: After two 10-second fame tests on the sample, the flame extinguishes within 30 seconds. Inflamer can not drop. V-1: After two 10-second flame tests on the sample, the flame extinguishes within 60 seconds. Inflamer can not drop. V-2: After two 10-second flame tests on the sample, the flame extinguishes within 60 seconds. Inflamer can drop.
Q:Does anyone know fire-proof material of fireproof wooden door?
Because the timber of fireproof wooden door has gone through fire retardant treatment, so it can prevent fire. Its principle: Fire-retardant treated timber has become flame retardant material itself and its fire endurance has increased. The commonly used method of fire retardant treatment for timber including: Spraying method, soaking method, boiling method, vacuum method, vacuum-pressure method. Spraying method and soaking method are generally used for timber surfaces which are no longer going through planing process, and thin plate fire retardant treatment, whose thickness is less than 10mm . Vacuum method and vacuum-pressure method have excellent flame retardant efficiency, but their equipment are expensive. Fireproof wooden door refers to the door whose fire endurance of door frames, skeleton of the door leaf, door panels made of timber or timber work reaches the provisions of "GB50045-95 design of tall buildings for fire protection".
Q:Who knows what is the external wall thermal insulation materials for level A fireproofing?
In general, external wall thermal insulation materials can be divided into level A and level B by combustion grading. Level A is non-combustible material, and level B is combustible materials. A few years ago, the fire of the CCTV Building and Shenyang Hotel put the blame on the level B material. At present, the level A material is widely used, and the prices of same level A materials may be even cheaper than the level B material. Level A material is generally divided into thermal mortar, phenolic foam board, rock wool board and foam cement board. I hope this information can be helpful to you. Hope you adopt.
