Q: Does anyone know the characteristics of refractory for glass kiln?: Refractory is a kind of non-metallic material with refractoriness not less than 1580 ℃, which has better thermal shock resistance and chemical erosion resistance, low heat conductivity coefficient and low expansion coefficient. Refractoriness is the centigrade?temperature of refractory cone specimen wiyhout any load resisting high temperatures without melting down Refractory is widely used in industries like metallurgy, chemical, petroleum, machinery manufacturing, silicates, power, etc., which is mostly used in the metallurgical industry, accounting for 50% to 60% of total output.

Q: What are the materials for refractory materials? What are their names?: High temperature oxide materials in refractory special applications, such as aluminum oxide, lanthanum oxide, beryllium oxide, calcium oxide, zirconium oxide, refractory compounds, such as carbides, nitrides, borides, silicides and sulfides; high temperature composite materials, including metal ceramics, high temperature inorganic coatings and fiber reinforced ceramics.

Q: In entering fire door, which material does well?: Hello: The basic material has steel, wood, or steel. The fireproof sandwich board, such as rock wool and perlite. The material of fire door, fire door has steel fire door and wooden fire door. There is no doubt that wooden fire door can't be used as entering door. In the steel fire door, two layers of steel plate in the clip is flame retardant material. In general, there is no lock. Of course, you can add locks in it, but it doesn't have pry proof function. I hope my answer can help you.

Q: what is the fireproofing material of engine room? who knows it ?: 1. The new type fire?retardant?coating in fire retardant coating, the expanded vermiculite, expanded perlite heat insulation material and cenosphere adiabatic powder, etc. These inorganic component, is a major part of the thick coating type of fireproof coating, and they also are the major factor affecting the level of performance of fireproof coatings. The fireproofing thermal insulation properties of fireproof coating, is mainly determined by the fire back surface temperature of this factor, but also related to the fire endurance. If it reaches the same temperature for a longer time, it shows that it's fireproof thermal insulation is better, and the fire endurance therefore is higher. 2. The new fireproof board new fireproof board now is welcomed by the people and the important factor is its environmental protection, and with the increasing high-rise buildings, the fire protection requirements and strength requirements are also rising, it is a big challenge for the performance and standard of the fireproof board.. Now fireproof board is mainly used siliceous material or calcareous materials, and then mixed with the fiber material, lightweight aggregate, adhesives and chemical additives, it is not only be fireproofing, but also improve their thermal insulation performance, and light weight, good carrying capacity, good durability, no aging problem, more importantly, it is good in environmental protection.

Q: Detailed description of magnesia dolomite refractory material?: The use of low chromium or chrome free refractories is more and more widely used, developed countries in the development of chrome free refractories to replace the chromium containing material, through research and production practice show that dolomite refractories is the refining of AOD furnace, large cement kiln ideal material.

Q: Firing high temperature kiln of refractory and internal temperature being as high as 1600 ℃, metal heat exchanger can't use, how to do?: Directly using silicon molybdenum kiln, the temperature is better. Now using the electricity is cheaper than the price of other fuels.

Q: What's the fire resistance rating of the exterior fire?retardant?coating?: Current fireproofing material is mainly classified into five grades: A class: Incombustible building material which is almost incombustible. A1 class: It is noncombustible and cann't cause open fire. A2 class: It is noncombustible but needs to measure the smoke it will cause and that should be qualified. B1 class: Flame-retardant building materials: Good in fire retardation, it is non-combustible when meeting open fire in the air or under high temperature, and it is difficult for the fire to spread quickly. Besides, when the fire source is removed, combustion stops immediately. B2 class: Combustible building material: It has certain fire retardation. In the case of open fire in the air or at high temperature, it will immediately burst into flames, and easily lead to the spread of fire, such as the spread to wooden pillars, timber roof truss, timber beams, wood stairs, etc. B3 class: Flammable building material has no fire retardation effect at all. It is highly combustible with big fire risk. Besides, the classifications of fire resistance rating of building materials are different according to different standards: dDIN4102: A1, A2, B1, B2, B3; x0dEN13501-1: A1, A2, B, C, D, E, F. Hope it helps.

Q: how long is the fire endurance of plasterboard?: Gypsum board is flame retardant materials, combustion performance rating B1, but when mounted on a steel joist, it can be seen as rating A(non-combustible material) . So it is fine to use as a ceiling. You can randomly choose several samples to run some tests at the quality inspection insititute and the quality of these samples are subject to the testing results.
