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:Pals who know something about fire resistant material please tell me how many types of refractory material there are
Classified into ordinary and special refractories. The ordinary refractory material is calssified into acid, neutral and alkaline according to the chemical property. Special refractory material is calssified into high temperature oxide according to the composition for , infusible compound and high temperature composite in addition, can be divided into ordinary refractory products according to the fire intensity (1580 ~ 1770 DEG C), high-grade refractory products (1770 ~ 2000 DEG C) and special refractory products (2000 DEG C above). According to the products shape can be divided into bulk (standard brick, special-shaped brick block, special shape (crucible, sagger, pipe, etc), fibrous shape (silicates of aluminum and zirconium oxide and boron carbide matter) and irregular shape (fireclay, refractory castables and incompletely material).
Q:How many hours of the fire endurance time of the rock wool laminboard?
Limit is usually two hours. Pay attention to it please.
Q:what's the materials of fireproof housing?
I'm very glad to answer for you. 1. Mobile homes in high-rise buildings, as for the interior hidden artifacts of single and multi-layer mobile homes, when its fire endurance is ruled above 1.5 h, you should choose the non-swelling large activity fire retardant coating; 2.as for Indoor mobile house, light roof mobile house and mobile house need to be decorated, when its fireproof limit is ruled under 1.5 h, you can choose swelling mobile house fire retardant coating; 3. The fire endurance of mobile houses need to be above 1.5 h, outdoor mobile houses project shoule better not choose swelling fire retardant coating. 4. Indoor mobile houses extremly need to be decorated, hot standby is a living place of mobile houses, bearing steel structure of equipment, bracket, the part easy to be knocked like skirt, its fire endurance needs to be above 1.5 h, you better choose fireproof panel of mobile houses. 5. Open mobile houses, you should choose fire retardant coating of mobile houses suitable for outdoor, and use the coating with over one-year outdoor mobile houses project operation and the coating function without significant changes. 6. multiple layer coating should be matched with each other, the bottom layer coating should be able to be used with rust-proof paint together or have rust-proof function. 7, while choosing the fire retardant coating for special function, it should have over one-year project operation and verification case and matched fire-proof function.
Q:What kind of refractory material should be used for common boiler?
Build by using clay refractory mortar. Common clay brick is used as combustion layer. Xindeyuan Refractory Material, red brick is used as external wall. Light clay brick is used as thermal insulation layer, thank you.
Q:How long is the duration of fire resistance that fireproof window of level B can endure?
Level B refers to the fire resistance rating and different hours in fireproofing of the fireproof window. Fireproof window of level A can endure fire for 1.5 hours while level B, 1.2 hours
Q:The history of refractory material
Q:What is the definition and classification of amorphous fire resistance materials?
9.8. brick made of refractory bone material and powder material can be used directly or after adding appropriate liquid formulation Refractory paint. Refractory slinging material 6. Prefabricated cubes, bonding agent or other additives. fire-resistance sparying material compround additives. Refractory pressed into the material, binder. Refractory ramming material 3, The material is a new fire proof material without calcination Heavy aggregate and lightweight aggregate: Inorganic binding agent and organic bond, its fire resistance is not less than 1580. Refractory castables 2 mouldable refractory Classification according to the type of bonding agent: 1. Classification according to refractory aggregate. According to the production and construction method, refractory mud or refractory mire, with a certain proportion of the mixture
Q:How is the grading of the level A new material fire insulation material?
The standard to distinguish level A and level B is the different fireproofing coefficient. The level A is non-combustible. The level B is divided into B1, B2 and B3. B1 is flame retardant, B2 combustible and B3 flammable. The level A is commonly phenolic aldehyde, rock wool, thermal mortar, foam ceramics, foam glass and foam concrete on the current market. Among the advantages of level A materials, the biggest one is foam concrete currently, also known as foam cement, which the Xuzhou Green Year EEB company's main produces.
