Q:I am a manufacturer of refractory materials. I would like to receive some orders from abroad. I would like to know what foreign trade companies in Dalian place foreign orders abroad
Dalian foreign trade companies are numerous, and fire prevention materials are also quite a lot
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 between first-level fire-resistant materials and second-level fire-resistant materials?
The combustion performance of materials could be divided into: A( noninflammability), B1(flame retardancy), B2(flammability), B3(inflammability). Building materials are divided into four ranks according to these properties. 1. In accordance with Code for Design of Building Fire Protection(GBJ16-1987)(revised edition in 2001), fire hazards in producing and storage can be divided into five types. In Fire Prevention Code of Petrol Chemical Enterprise Design(GB50160--1992)(revised edition in 1999), classification of fire hazards is also achieved according to the hazards of materials that have been using, producing and storing. Measures in prevention of fire explosion could be taken from the perspectives of fire separation, fire resistance level of structures, allowable floors, safe evacuation, and fire extinguishing facilities based on different levels of fire hazards. 2. Four fire resistance rating of buildings are listed in the book Code for Design of Building Fire Protection. And specific stipulations are made to the fire resistance of main elements of buildings, such as bearing walls, beams,pillars, and floors. When designing a building, if permitted, refractory materials of high-rank should be adopted in those buildings which have high potential fire hazard and a lot of combustible material and valuable equipment. While making sure fire resistance rating, the duration of fire resistance of each elements should meet its requirements.
Q:What's the material of electrical fire prevention board?
Electrical fire prevention board uses the material of inorganic binders, which mainly includes water glass, gypsum, phosphate, and cement; refractory mineral fillers: alumina, asbestos powder, calcium carbonate, perlite, cornstarch and etc.; electrical fire prevention board is mainly aimed at fire protection and thermal insulation. Iron plate is electrically conductive with good thermal conductivity, which will cause the result that the equipment is not insulated and suffers larger superheating surface. Hope my answer is helpful for you.
Q:Can I use ordinary cement with the addition of sand, clay, and salt as refractory material to paste the stove?
Add some hair and slags, or it will crack before calcination.
Q:who knows the fire endurance of fireproof coating?
fireproof coating of different thickness differs in its fire endurance. Let me intrduce you as follows: The amount of time of 0.5 hours refractory thickness 0.45mm 0.79kg / m21 hr 0.9 mm 1.5kg / m21.5 hour 1.4 mm 2.3kg / m22 hr 2.0 mm 3.3kg / m22.5 h 2.8 mm 4.6 kg / m2
Q:What's the A grade fireproofing material?
1. fire-proof plate; 2. fireproof wooden door; 3. fireproof wooden window frame; 4. fire resisting shutter; 5. fireproof and mothproof wood; 6. fireproof glove compartment; 8. fire retardant coating; 9. fire-proof sealing material.
Q:How many refractories are there for boiler above 1200 ℃?
In addition to refractory brick, refractories include refractory concrete (refractory cement+aggregate), fire-resistant insulating layer (refractory cement+vermiculite powder or refractory cement + diatomaceous earth) and the like. Refractories often used are azs brick, corundum brick, direct-bonded magnesia-chrome bricks, carborundum brick, silicon nitride bonded silicon carbide brick, nitride, silicide, sulfide, boride, carbide and other nonoxide refractory materials, calcium oxide, chromium hemitrioxide, aluminium oxide, beryllia and other refractories. Thermal insulation refractory materials often used are diatomite product, asbestos product, insulation board,etc. Unshaped refractories often used are repairing mass, ramming mass, castable refractory, plastic refractory, refractory mortar, refractory gunning mix, sling refractory, refractory coating, lightweight refractory castables, stemming, etc.
Q:What parts of cement kilns are refractories used on?
These parts are decomposition furnace, smoke chamber, kiln, kiln hood, grate cooler, tertiary air duct and coal pipe.
Q:Who knows which chrome refractories produced by the Henan refractory plant can be used for continuous casting?
Chrome drainage sand can be used for coupling process there are many manufacturers do it, this is mainly a lot of chrome, chrome iron ore mainly refers to the drainage sand, adding ladle material amount regulator performance guide. Drainage sand as filling material of ladle bottom nozzle, one hand can be sintered at low temperature, to avoid joining the molten steel drainage sand floating accident, on the other hand, in the high temperature and long time refining steel surface can not meet the state of sintering is too thick, otherwise it will affect the automatic pouring rate, Hua Heng worth a try I'm not favored, my sky is the wind or rain rainbow you hate yourself in the manipulation of really useless emotional heart to still ache for breaking up before the sorry shuttle time in the moving picture of the clock in the opposite direction when the initial time begins to move back to love you
