$calcined bauxite for refractory bricks$

Q: Do you know what the main indicators are for the inspection of refractory materials? Thank you very much for your requests and reports: Porosity, volume density, water absorption, true density, thermal expansion, thermal conductivity and heat capacity.

Q: How many kinds of A-level fireproof and thermal insulation materials are there?: Please give us some information about the kinds of A-level fireproof and thermal insulation materials in the market.

Q: What the fireproofing materialare of the refractory kettle and where they can be sold?: Many places sell these. Nearly 10 years, can't brun when it is dry, adsorption. You can also baidu these materials. Heat transfer evenly, feldspar, clay and other raw materials with a ceramic products. Traditional casserole can not resist heat difference and also can withstand for 100 high temperature without crack. Aiming at the problem of traditional casserole, easy to crack and air permeability, people joined the spodumene on raw material, produce a high-temperature resistance casserole. It is produced after the high temperature burning makes an earthenware pot to keep the original advantages. Hebei has many places to sell these materials and is also relatively cheaper. The traditional casserole has features of not easy to transfer heat's quartz and slow cooling. Due to production technology and raw materials, it greatly improves the casserole' practicability after research and improvement.

Q: Urgently!! Refractory problems, online, etc.: I feel that is the coating package, the coating of water is too large, the retaining wall in fused powder hydrated, can not produce strength under high temperature. What do you think?

Q: What characteristics do A grade external wall fireproofing material have?: 1. Save space and reduce costs; 2. Fireproofing, green and environmental protection; 3. Waterproofing; 4. Sound insulation; 5. Thermal insulation; 6. Install easily and shorten the construction period; 7. High safety performance.

Q: Fire rating of decoration materials: code for fire protection design of buildings

Q: What are the common refractory insulation cotton material?: I know less about this, I hope the following will help: Fire resistant thermal insulation material mainly refers to inorganic thermal insulation material and compround thermal insulation material. According to the shape can be divided into: Fibrous finishes, slag wool, rock wool, glass wool, aluminum silicate cotton. ceramic fiber, micro pile of diatomite, calcium silicate, expanded perlite, expanded vermiculite, aerated concrete etc., foam like bubble glass, volcanic ash glass, foam clay, foaming concrete, paste powder polystyrene particles insulation slurry

Q: Who know about the knowledge of acid refractory material? Please explain in detail.: Refers to the silicon dioxide

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 are grades of refractory materials?: Refractories have lots of varieties which all have different purposes. It is necessary to classify refractories scientifically in order to scientifically study, choose and manage them. Classification methods of refractories include chemical properties classification, chemical composition of mineral classification, manufacturing technique classification, morphology of the material classification. 1 divided according to the level of refractoriness: ordinary refractory materials: 1580 ℃ ~ 1770 ℃, advanced refractories: 1770 ℃ ~ 2000 ℃ and super refractories: above 2000 ℃ 2, divided in accordance with shapes and sizes : Standard ones: 230mm × 113mm × 65mm, no more than four ruler.
