Q: A chemical problem with refractory materials
In chemistry, there is never absolute
Q: How is the division of the fire resistant level of the rock wool board?
It's like this: China's national standard GB8624-97 divides the combustion performance of building materials into the following grades. Level A: non-flammable building materials. Level B1: flame-retardant building materials. Level B2: combustible?building?materials. Level B3 flammable building materials. section II Combustion performance and fire endurance of building components. First, The combustion performance of buildings of building components. The building is composed of components, such as foundation, walls, lubrication columns, beams, plates, roofs and stairs, ect. Building components are constituted by the building materials, whose combustion performance depends on the combustion properties of the used construction materials. Section One Combustion performance of building components. The building components are divided into three categories according to their combustion properties. First, non-combustible component: the component made by incombustible?materials. The incombustible?material refers to that when meeting the Oxygen in the air, it will not burn.
Q: What refractories have good mechanical property resistance and heat expansion and cold contraction property?
Aluminium oxide ceramics. I would like to know that what kinds of refractory materials can combine together and what kind of masonry way can be used for these materials so as to achieve the perfect combination.
Q: Who knows what kind of material the fire-proof plate use, and is it good?
It is the decorative board made by adopting silicious material or calcareous material as the main raw material, and blending them with certain proportion of fibrous material, lightweight?aggregate, adhesive and chemical?additive before steam pressing. It is a kind of new material and more and more frequently used currently not only for it is fireproof. Construction of the fire-proof plate has higher requirements on the adhesive, and the price of the fire-proof plate with better quality is more expensive than that of the decoration panel. The thickness of the fire-proof plate is generally 0.8mm, 1mm, and 1.2mm. So it is the best material for making cupboards.
Q: What antioxidant will be used in refractories?
Antioxidant: Si, Al, Mg, Ti, AlSi, AlMg, SiC, TiC, ZrC and these metal nitride, boride. Sintering agent: different mechanism, Cr2O3 to promote the sintering of alumina;CaO/MgO style promote ZrO sintering;Siliceous ramming material to add boron bottles, magnesia coating and clay, etc.
Q: What is the most reasonable drying heating curve of magnesia refractories? Products of less than 0.5T
o
Q: What are the characteristics of the carbon composite refractories?
The features of carbon composite refractories: 1. It is with an aggressive high thermal shock resistance 2. Good resistance to molten steel and slag
Q: What are the materials used in refractory material processing?
AZS special refractory brick, corundum brick, magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, alumina, Magnesium Oxide, beryllium and other refractory materials. Often used insulation refractories are diatomite products, asbestos products, insulation panels and so on. Unshaped refractory materials commonly used are fettling, refractory ramming material, refractory castable, refractory plastic material, refractory clay, refractory gunning, refractory cast material, fireproof coating, lightweight castable, mud etc..
Q: how long is the fire endurance of plasterboard?
fireproof endurance can reach a maximum of 4hours, suitable for a variety of public buildings firewall, and partitions for public exit passageway, reaching standard level of fireproof. the lightweight partition made of gypsum board and steel stud is mainly for dividing architecture space. Rock wool can be filled in the mddle according to its design requirements, using different series of gypsum board, steel stud. the walls may have fire resistance and sound insulation property of various degrees.
We has been adhering to scientific and technological innovation as the company development ideas, establishing the export-oriented development strategy and has close technical cooperation with scientific research institutions.We supply many kinds of calcined bauxite.
