FUSED SILICA SAND FOR REFRACTORY

Q:What are the raw materials of refractory?: Refractory is mainly resistant to high temperature and fire. Sic refractories are widely used in refractory. I hope my answer will be helpful to you.

Q:What's the organzational structure of refractory material?: Ingredients (harmful); phase composition. The main components of refractory material include chemical composition and phase composition. The addtional components include main crystal phase, matrix, crystal phase, chemical composition

Q:What types does refractory floor include?: It includes ecoplates, chipboard,density board, composite?board, etc. Wherein ECO-plate is solid wood board, and it is environmetanl and healthy. Its nail-holding ability and flatness is much better than that of chipboard and solid wood particle board. After all it is solid wood board. But we must pay attention to whether the eco-board is produced in the original factory. According to our original factory, the board only produced by Treezo Group and Dede board are the original.

Q:How to apply the alumina powder on refractories?: What kind of the refractories can make the aluminium oxide increase the aluminum content and specific gravity, and erosion-resistant.

Q:What's the maximum temperature that the high-temperature resistant refractory ceramic fiber cotton can endure?: It depends on what material the ceramic fiber gasket uses. It’s usually referred to high temperature gasket made from ceramic fiber paper. It is generally classified into normalized form and high alumina type, of which the former can resist the maximum temperature of 1260℃ and its continuous use temperature is 1000℃, and the latter can be used for a long period at the temperature of 1200℃. Nichrome wire, stainless steel wire and glass fiber are reinforced. Ceramic fiber coating cloth and slag cloth, sintering ceramic fiber cloth and ceramic fiber fumigation cloth) Characteristics of the ceramic fiber cloth: It has high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment.

Q:What is neutral refractory? Can refractory suppliers tell the main components of it?: The material using Al2O3, clay, bauxite and corundum as the main components is neutral material; the material using MgO and CaO as the main components is basic material; the material using SiO2 as th emain component is acidic material.

Q:What's the A grade fireproofing material?: Main materials are steel, wood, steel and wood. Fire door is one of the measures for buildings fire separation, and it is generally installed at the firewalls, entrances and exits of stairwells or tube well openings, which is required to play the role of fire protection and smoke control. Fire door plays an important role in preventing the spread of smoke and fire and reducing damages, so it must be strictly required. Fire dooor is classified into three classes of A, B, C, and their fire insulation and fire integrity is greater than or equal to the following values: A class fire door: 1.5h; B class fire door: 1.0h; C class fire door: 0.5h. It is in accordance with the provisions of 4.5.1.2 Article in GB12955-2008 "New Standard of Fire Doors".

Q:Who knows about the fire endurance of A grade fireproofing glass doors?: The fire endurance of A grade fireproofing glass doors should be no less than 3 hours. A grade fireproofing glass doors use common glass of 6 mm. The shock resistance of float glass is about less than 5 min, and that of toughened glass is about 15 to 30 min. Fireproofing glass is classified in accordance with fire rating, the fire endurance of which is usually from 30 to120min, and that of the most common fireproofing glass is 60 to 90min, but now the market is a mixed bag, the so-called fireproofing glass is generally fake ultra-strong tempered glass. Therefore, you should buy the genuine glass with formal certificates, or you will bring yourself great inconvenience, and even more serious consequences.
