Q:Who knows the setting requirements of roofing fire barrier zone?
curtain wall style architecture should meet the following requirements: The space between the inner cavity of the base wall and curtain wall and base wall, pier between two windows, window sill wall and skirt wall should be sealed by the fire-proof sealing material at each floor. I hope I can help you!
Q:What are the refractory materials above 1000℃
corundum would be fine
Q:what materials can make external wall fireproofing paint have the fireproofing effect
First, the width of fire barrier is greater than 30CM, and the thickness should be same to the thickness of insulation material. fire barrier zone insulation board must do the whole area sticking construction with the base wall during the construction. fire barrier zone insulation board is required to assistant binding by anchor bolt, anchor bolt must suppress the underlying mesh. fire barrier zone should be set at the upper position of door and window openings, the distance between the low edge of isolation belt and the upper edge of the window must be less than 50cm. When the fire barrier zone is set on the edge of the window, fire barrier zone at the upper part of the window should do flanging when sticking, flanging glass fiber mesh must exceed 10CM than firebreak insulation board. flanging network, underlying network and surface network can not be overlapped or butted at the top of the window. the thermal resistance of fire barrier zone must be half than EIFS thermal resistance in the cold northern areas, while the thermal resistance of fire barrier zone must be three times than EIFS thermal resistance in the hot summer and cold winter area. Cement foam insulation board is recommended to use as external insulation board materials, level A exterior wall cement foam insulation board is a new ultra-lightweight thermal insulation material, with the advantages of lightweight concrete and insulation performance, with characteristics of low production costs, simple process, easy to operate, small product density in 180250kg / m3, high strength, low water absorption and good insulation properties, thermal conductivity of 0.05 ~ 0.07W / m · K and level A non-combustible; it is suitable for external wall insulation and fire isolation belt, and can meet the urgent needs of the market of exterior thermal insulation. With the increase of the intensity of the building fireproofing, the products will become the leading products in building insulation market in the future.
Q:what's the requirements of refractory for forge furnace?
accurate answers please refer to Current Situation and Development Trend of Refractory Material in Heating Furnace ,Quality Requirement of Modern Industrial Furnace Refractory Material(GB/T17638-1998) Standard,Furnace-constructing Technology, if you need the mail box, please senf e-mail to me, my QQ number: 249704548.
Q:What are the requirements of the performances of brasque refractory?
The requirements of the performances of brasque refractory: 1, should have sufficient refractoriness and softening point under a fixed load. Because under the action of the electric arc, the inner and surface temperature of the different parts of the brasque can be up to 1500 ~ 1800 ℃. 2, should have strong slag resistance. Because the inward permeation of slag and smoke at high temperature through its pores of brasque cause melting loss of refractories, organization delamination and flaking. 3, should have good thermal shock resistance. Because in the steelmaking process, opening the furnace door, lifting the furnace lid will cause sudden temperature change of brasque refractory,flaking and cracking, resulting in premature failure of brasque. 4, should have sufficient strength, because the brasque will be impacted at the time of loading, vibrated when tilting, flushed by metal, slag and gas flow when boiling. 5, the thermal conductivity and the conductivity should be small. Refractories commonly used for electric furnace include magnesia bricks, dolomite brick, high-alumina refractory bricks, silicious refractory brick and magnesite ramming material. Due to the different working environment of each parts of the furnace, refractories are different.
Q:What are the characteristics of thealuminium oxide refractory?
The substance used in refractories must have the following characteristics and properties: 1, High stability: Anti-oxidation, anti-reduction and thermal decomposition; 2, High melting point of 2800 degree; 3, Low price. The magnesium oxide refractories have all these three characteristics and properties, particularlly in the aspects of melting point and stability .
Q:Is there vermiculite in refractory?
Paint, small thermal conductivity, chemical, shipbuilding and other industries. Expanded vermiculite has excellent electrical insulating property, and it is stratified structure. It is a good thermal insulation material used in growing seedings, flowers and trees, bulidings, rubber and smelting. I hope my answer will make you satisfied. Refractory contains crystal water and board between its layers. For example, the interlayer of fireproof door contains expanded vermiculite, and after expansion, its specific gravity is 60-180kg& # 47. Electric insulation material. Expanded vermiculite is widely used for thermal insulation material and sealing material. Of course, some refractory also uses vermiculite; fireproofing material. Vermiculite is a good refractory material, whose maximum using temperature and unit weight can be repsectively up to 1,100 ℃ and 50-200kg/m3. When it is expanded, it is called expanded vermiculite. It is highly thermal insulated. Hard water softeners and paint. After unripe flake vermiculite is roasted in high temperature, its volume will expand 6- 20 times quickly. Friction materials, its volume can be quickly expanded several times to dozens of times. In addition. Quality expanded vermiculite
Q:How much is the duration of fire resistance of the porous brick shale?
It’s said on the internet that 950℃ is moderate and don’t exceed 1100℃, or the bricks are inclined to be melted.
Q:What is the use of refractory?
It is fire-retardant and insulated.
Q:What's the difference between refractory metal raceway and fireproof raceway?
Fire protection slot won't cause fire accident under the temperature of no more than 200℃. While the refractory cable tray is made with refractory materials and can withstand high temperature of 800℃ with no fire accident happening. The test standard depends on the maximum temperature it can endure. Hope it's helpful for you!
