FACTORY:
- Q: How many kinds of A-level fireproof and thermal insulation materials are there?
- A-level non-combustible materials are mostly inorganic thermal insulation materials, as well as some organic compound materials can also be non-combustible; but if the convenient construction is required, panels are exempted, you can only choose inorganic thermal insulation mortar.
- Q: How many kinds of fireproof materials are there in the market?
- I wonder that how many kinds of fireproof materials are there? Does anyone know about it, please tell me, thanks
- Q: What is the requirement of refractory concrete for raw materials? What is the main principle of commercial mixing station?
- There are many kinds of raw materials used, three, two aluminum oxide is one of the most commonly used raw materials, as well as alumina, hollow ball, Magnesium Oxide, zircon, etc., or the specific design temperature and the use of parts.
- Q: Who knows how to divide the building fire grade and fire resistance grade?
- I hope to help you building fireproof rank division is one of the most basic measure in building fire safety technical measures, Building's fireproof rank is divided into class one, two, three, four according to China's architectural design specification. Fire-resistant capability of the highest level is the strongest; Fire resistance of four level of the weakest. The fire resistance level of a building depends on the combustion performance and fire resistance of the building components that comprise the building. The so-called building component refers to a series of basic components, such as wall, foundation, beam, column, floor, stair, ceiling and so on.
- Q: What's the refractory material in common use currently?
- According to its category, raw material of basic refractory: Mainly magnesite (magnesia), dolomite, lime, olivine, serpentine, high alumina material (sometimes neutral); main neutral raw material: chromite, graphite, silicon carbide (artificial).
- Q: How should fireproof building materials be ranked?
- 5. Civil building 5.1. Fire resistance rating, number of layers and floorage of civil buildings 5.1.1. Fire resistance rating of civil buildings should be classified into four levels of first, second, third and fourth. Unless otherwise specified in the code, the combustion performance and fire endurance of building components with different fire resistance rating should be no less than that of the regulations in Table 5.1.1. Table 5.1.1: Combustion Performance and Fire Endurance (h) of Building Components (Figure) Note: 1. Unless otherwise specified in the Code, the fire resistance rating of the building with wooden pillars as load-bearing and incombustible material as the building wall should be the fourth level; 2. For the suspended ceiling of the building with the second level of fire resistance rating, if it uses non-combustible component, it won't be limited in its fire endurance; 3. For buildings with the second level of fire resistance rating, if it is really difficult for the partition wall of rooms with the area of no less than 100m2 to implement the regulations of the Table, the partition wall can adopt the non-combustible component with fire endurance of no less than 0.3h; 4. For buildings with the first or second level of fire resistance rating, if it is really difficult for the partition wall of both sides of the evacuation walk to implement the regulations of the Table, the partition wall can adopt the non-combustible component with fire endurance of no less than 0.75h. 5. Fire endurance and combustion performance of the residential building component can be implemented in accordance with the provisions of current national standard GB 50368 "Residential Building Code".
- Q: What kind of refractory bricks material is best?
- It depends on your purposes. In general, aluminous fireclay brick is usually used. GB/T 3994-2005 insulating fireclay brick. Bricks with good textile are as follows: high-grade thermal insulation refractory brick, GB/T 3995-2006 high alumina thermal insulation refractory brick. Model is A13, and the texture is aluminium oxide. A13 50u, high grade heat insulating brick B5; intermediate heat insulating brick B2, etc.
- Q: What are the new types of refractories? What are the characteristics? Their applications and developments?
- AZS refractories are often used brick, corundum brick, magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, alumina, Magnesium Oxide, beryllium and other refractory materials.Often used insulation refractories are diatomite products, asbestos products, insulation panels and so on.Unshaped refractory materials commonly used are fettling, refractory ramming material, refractory castable, refractory plastic material, refractory clay, refractory gunning, refractory cast material, fireproof coating, lightweight castable, mud etc..
- Q: Does the aluminum silicate thermal insulation material fireproof?
- Yes, because of its low heat conductivity coefficient, and good thermal insulation, it can be setting fire.
