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 is carbon composite refractories? I hope that the answer is in detail.
Q:How can the furnace be replaced after the gasifier or water wall is replaced with refractory material?
The furnace shall be made according to the type of refractory and the moisture content and the type of bond. Pay special attention to the discharge of free water and crystalline water, not too fast to prevent cracks!
Q:How to understand qualitative and qualitative refractory materials?
Such as amorphous refractory castable, referred to as bulk loading, cast material, ramming material, refractory clay etc., utensils and other special products. Amorphous refractory material products, refractory heat insulating bricks and experimental and industrial crucible, spraying materials, such as burning bricks, electric melting brick, turn it into required shape and process heat treatment in where it is used.
Q:Who knows the fire endurance of rock wool color plate?
I'm glad to answer your question and offer you some of my experiences, for reference only. rock wool board is artificial inorganic fiber taking basalt as raw material and produced by melting with high temperature, which has characteristics of lightweight, non-combustible, heat absorbing, small thermal conductivity. The initial research is a common type of application in the building mainly used for industrial buildings which should be consistent with provisions in "the application types and basic requirements of building insulation materials". Successfully tested in June, 1981 Rock wool board is a new type material with fuctions of thermal insulation, fire retardant, sound absorption. The fire endurance of general rock wool board is 140-180 degrees, within two hours, better not exceed this safe period, in order to avoid security risks.
Q:What are included in roof thermal insulation fireproofing material?
Aluminium foil, bubble, aluminium foil/air bubbles/fireproofing aluminium foil thermal insulation material, fireproofing bubble thermal insulation material, fire retardant thermal insulation material, thermal insulation construction materials, aluminum foil insulation material.
Q:What kind of foundry ingot refractory materials are there? Please be more detailed.
Classification of refractory materials used in foundry smelting process: refractory brick, siliceous brick, high alumina brick, corundum brick, magnesia brick, magnesia brick, magnesia carbon brick. Unshaped refractory materials: ramming material, castable, refractory cement, silica, magnesia, etc.
Q:who knows how to classify the fire resistant levels of fireproofing material?
Materials used in construction are called construction materials. The combustion performance of construction materials refers to all physic and chemical changes happened when burning or contacting fire, the properity is measured by combustibility of material surface and flame transmission, heating, smoke,charring, weightlessness, and the producing of toxicity resultant. Our national standard GB8624-97 classifies the combustion performance of construction materials into following several levels. Class A: Incombustible building material, class B1: Nonflammable building material, class B2: Combustible building materials, class B3: Inflammability construction materials, generally speaking: first fire resistant level construction is the mixed construction of reinforced concrete structure or brick wall and steel concrete structure; second fire resistant level construction is the steel structure roof truss, reinforced concrete column or mixed structure made by brick wall; third fire resistant level construction is the wood and brick made by wooden roof and brick wall; fourth fire resistant level one is the combustible structure made by wooden roof, hard-comnustible component wall.
Q:Does anyone know the refractory temperature of fire-resistant glass?
Ordinary glass will be completely liquefied in the furnace of about 1100 degrees for half an hour and will not deform below 600 degrees. toughened glass fire-resistant glass is the product of ordinary glass after being processed Glass will mainly burst after encountering fire. When unevenly heated or encountering sudden drastic changes in temperature, ordinary glass will burst if the sharp temperature difference is over 70-120 degrees and toughened glass will burst at 200 degrees. It is not yet clear of the bursting temperature for the refractory glass. (I hope this answer can help you!) Hope you adopt !)
Q:What are the differences of ceramics and refractories? Is the ceramics belonging to refractories?
The ceramics and refractories are different with the porcelain ceramic with high temperature of 1300℃ as household porcelain refractory. The porcelain refractory material of 1450℃ as the same as the aluminum oxide, kaolin, refractory clay and other raw materials demand the deployment ratio of the raw material the same as the temperature.
