- Q:What's the heat conductivity coefficient, specific heat capacity and density of the refractory material of magnesite-chrome brick and magnesia-alumina brick respectively?
- It is suggested that you find some samples of well-known manufacturers, such as Ogilvy and Mather Group, and that will be more correct.
- Q:Please answer the questions about the packing and transportation requirements of refractory materials.. Requirements for packing of refractory bricks
- Bricks are usually made from pallets.Generally take the automotive, coastal sea city.
- Q:What is the limit of fireproof rolling shutter?
- Fireproof rolling shutter door is a kind of fire protection and heat insulation facility which is suitable for the large openings of buildings, having a certain effect on the design and installation. Fire shutter doors are widely used in fire partition of industrial and civil building. It can effectively prevent the spread of fire, to protect the safety of life and property. It is an indispensable modern building fire facilities. According to the national standard 14102-2005 GB standard, the provisions of 14102-2005 GB specify that: If fire resistance limit of fire resisting shutter is no less than 3 hours, it is AAA fireproof rolling shutter. Therefore, the fire resistance limit of AAA grade fireproof rolling shutter should be 3 hours.
- Q:Is there anyone who can explain how to grade the level of fire insulation board?
- The classification of fire proof level for thermal insulating material 1, Burning performance of building material can be classified into the following several grade according to national standard GB8624-97: Non combustible building materials: Non-conbustible material. Class B1: Refractory building materials: Flame retardant materials have good flame retardant effect.
- Q:what's the classification of fireproof materials?
- Fireproof materials are used in construction, in various forms and it has played an absolute role in modern fireproofing, common fireproofing materials include fireproof?panel, fire door, fireproofing glass, fire?retardant?coating, fireproof bag,etc Or the material itself has a high temperature resistance, heat-resistant, flame-retardant properties. Most of them are used for the construction industry.
- Q:What are the fire resistances of grc partition panels?
- waterproofing: It has good water resistance; 2. fireproofing: fire resistance of partition panel≥3.5h, it has an excellent fireproof performance and can be applied to fire-proof bulkhead; 3.soundproofing: According to the different thickness of walls and surface treatments, perlite light partition panels insulation can be 40-50 decibels, to ensure that products can be used for office, commercial, entertainment and residential buildings; 4, light weight:
- Q:I wanna ask that magnesium oxide is refractory?
- Magnesium oxide is used in refractory material, because it has the following characteristics and properties: 1, high stability: Anti-oxidation, anti-reduction, thermal decomposition; 2, high melting point, 2800 degrees; 3, low prices. In particular, the stability and melting point is very good, I hope I can give you help.
- Q:What material is used for making refractory stone bowl?
- Good refractory stone pot is carved from high-quality natural refractory stone in a professional way. But many are also made of synthetic materials, the price is lower, too.
- Q:Kinds of refractory mortar
- Refractory mortar can be divided into ordinary refractory material and special refractory material. Ordinary refractory materials can be divided into acidic, neutral and alkaline refractory materials chemical properties. Special refractory material can be divided into high temperature oxide, refractory compounds and high-temperature composite materials according to their components. Furthermore, according to refractoriness, it can be divided into general refractory products (1580 ~ 1770 ℃), high grade refractory products (1770 ~ 2000 ℃) and super refractory products (2000 ℃ above). It can be divided into bulks (standard bricks, special-shaped bricks, etc.), special shapes (crucible, sagger, pipe, etc.), fibrous (aluminum silicate, zirconia filter and boron carbide , etc.) and indefinite shape (refractory clay, pouring materials and ramming mass, etc.). According to the sintering process, it is divided into sintered products, fused cast products and melting jetting products.
- Q:Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?
- If the outer packing is made of solid wood, it must be fumigated! If it is not solid wood, you can do without!
