Q:What is the fire endurance of ceramsite concrete blocks?
What is mentioned in fire safety rules is that the fire endurance of 240mm thick hollow brick of ceramsite concrete is 2.9h, so 190mm thick hollow brick is 3h. B05 thickness(mm), fire endurance(h). Combustion performance 100 4.0. Non-combustible component 150 6.0200 8.0300 〉8.0B06 100 〉4.0150 〉6.0200 〉8.0300〉8.0: The fire endurance performance of building blocks wall in the table is taken from the Tianjin Construction Standard "light steam pressing aerated concrete block" DB / T29-128.
Q:Refractories for iron-making blast furnace?
This question is too professional - as far as I know, there are blast furnace noumenon bricklaying - trough slag runner fire-resistant model ~ main channel carbon rod ~ ramming mixes ~ ~ I do not know the specific details.
Q:Can anyone tell me what material the first rate fire resistant door is?
Class A fire door materials are mainly steel, wood, steel and wood,and other materials. If there is filling material in a Class A fire door, it is generally the perlite. According to the actual situation in China, the fire doors and windows are divided into class A, class B, class C, whose minimum fire endurances are stipulated, namely class A 1.50h, class B 1.00h, Class C 0.50h. There are fireproof wooden doors and fireproof steel doors. whose main purpose is to achieve fire endurance time. But door closers are required to be installed.
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?
// Baike? Url x3d CQ3i6_yUCWUMgk3aaRGGLURNtvKPl5IdZpj35Yvommk7Nyif0IJD-SkdIW29GCHwLpb9cT9Ii25GLcEJg-ZHcq "target x3d" _blank "x26gt; http://baike.baidu.baidu.
Q:How long can gypsum board endure fire?
General gypsum plaster board with a thickness of less than 12mm has a fire endurance which is less than half an hour. Scheme One of gypsum board partition system by using 75# series of lightgage steel joist: separation distance of keels keep 600mm in vertical direction. The thickness is greater than 0.5mm; gypsum board: it shoule be the board of double-sided and single-layer with the thickness of 12mm. Fire-resistant gypsum plaster board's fire-resistance limit: 1 hour. Sound insulation index: over 35 rwdb.
Q:What kind of materials can be tested their electrical resistivity in the current refractory industry?
Graphite, Magnesium Oxide, and alumina are all feasible.
Q:how is the high-temperature flame-retardant fibre board?
------ Different category of high temperature materials including refractory and heat-resistant material, inorganic compounds, high-molecular polymer. refractory usually refers to an inorganic material that can endure temperature above 1580 ℃ . They are for building kiln, combustion chamber and other buildings that require heat resistance materials. It is generally made of quartz sand, clay, magnesia mineral, dolomite.
Q:Who knows the new fireproof and thermal inuslation matertial?
Ceramic foam insulation board, XTP vacuum insulation panels and a variety of composite insulation panels, etc. Relatively speaking, the inorganic insulation board is a trend. In terms of the overall performance, the cost performance of the foam insulation board is higher. XTP has the best performance, but with a little trouble in construction. Because of the vacuum characteristics, transportation and installation process should be very careful.
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.
