Q:How to measure the influence of high-temperature performance of the products refractory in the formation of the liquid phase.
Generally how can do high-temperature performance to measure how much liquid may affect hot bending strength rul refractoriness levels of high temperature creep?
Q:How to divided the grade of external wall thermal insulation materials?
Synthesized the three versions of GB8624 (1997,2006,2011), external wall thermal insulation fire rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. There are many technical indicators to make specific division, but I partly cannot report for a while, because it is very professional and technical. I hope I can help you!
Q:What is the importance of silicon powder in refractory processing?
in amorphousness it is mainly the mobility
Q:which kind of material is chosen for fireproofing window?
(1) window frame uses steel frame or wooden frame with certain strength that can safeguard the integrity and stability of the components. (2) steel frame and mound layer can choose galvanized steel sheet or stainless steel plate. Its selection criteria conform to the article 5.1 in GB12955 Steel Fireproof Door General Technical Condition. (3) the selection criteria of wooden frame and mound layer should conform to the article 5.1 in GB12955 Wooden Fireproof Door General Technical Condition. (4) the inside filler material of steel, wood frame should use incombustible material. (5) fire-resistant glass can choose test approved products without affecting the fire resistance of fireproofing windows . Light transmittance of glass should not be less than 75% of same layers commom sheet glass. (6) the sealing material between the frame and the fire-resistant glass should use flame retardant materials, it can play a role of fireproofing and smoke insulation in the fire.
Q:Fefractory of aluminium oxide.
Do you mean the alumina hollow ball brick? We can exchange private messages in specific.
Q:What is the function of refractory in ceramics?
Refractory is used as materials of kiln,sagger and kiln car for ceramic sintering. Its refractoriness is higher than ceramics, and the essential material and tool for ceramic sintering.
Q:How to make use of waste refractory materials whose main elements are alumina and mullite?
Crushing and pressing refractory bricks, or refractory parts . Such as welding positioner tracks use disposable tools.
Q:What are the characteristics of thealuminium oxide refractory?
Alumina refractory are characterized by uniform granularity, mobility, good dispersity. And it has good acid and alkaline slag erosion resistance, high strength, abrasion resistance, high melting point, erosion resistance , anti-flush and excellent thermal shock resistance.
Q:Who knows what is the standard of insulation material whose fire proof is level A?
Level A is distinct from B in coefficient of fire proofing. Level A is non combustible, while Level B is divided into B1( flame retardant), B2(combustible) and B3( inflammable). Currently in the market, level A materials are as follows: phenolic, rock wool, insulation mortar, ceramic foam, foam glass, and foamed concrete. The most advantageous of level A material at present is foamed concrete, also known as foamed cement. Xuzhou Lvchuang Construction company is working on this, you can search fro it on the internet, it has high cost performance.
Q:What are the differences between first-level fire-resistant materials and second-level fire-resistant materials?
1, these refer to fire resistance rating of building materials. 2, As for steel, elements that used in different parts should reach different duration of fire resistance according to fire resistance rating. For example, fire resistant pillars of first level can endure fire within 3 hours; the second level, 2.5 hours; the third level, 2 hours. With respect to beams, three levels of fire resistance are included.
