Q: What are the materials of white firebricks?: The commonly-used firebricks include alumina bricks, corundum bricks, chamotte bricks, high alumina bricks, diatomite bricks, zircon bricks, lightweight corundum bricks, zirconia bubble bricks and so on ~~~

Q: What are the fire endurance requirements of class A fire resistant door ?: Hardwares are professional fire resistant lock, fireproof?door closer, fire hinge, handle, latch and sequencer, and they can also be configured according to user needs. Fire resistant time of class A and B fire resitant door is 12h and 09h respectively. It can also be customized according to customer needs into a variety of non-standard specifications. Steel fire door is developed in accordance with the national standard GB12955-2008, and in line with ISO3008, BS476 standards. Requirement: fire endurance should meet the A,B and C fireproof requirements respectively. You can also choose to install hold-open door device to leep the door leaf usually in open. Doorframe and door leaf is made up of imported or domestic quality electrolytic steel plate, electro galvanized steel plate or stainless?steel plate, filled with quality expanded perlite fireproof?panel which can withstand high temperature above 1200 ℃. The surface is processd with electrostatic spraying plastics, and auxiliaries are stainless steel fire resistant lock (or pipe shaft lock ) , galvanization for steel (or stainless?steel) fire hinge, domestic(or imported) door?closer.

Q: Where is the production of refractory manganese alloy manufacturers? Manganese is recommended between 63 and 70!: The cut is relatively transparent if you jam, we have also used silicon manganese alloy

Q: How to detect the acid resistance of refractory? Is there any standard? Thank you: What material it is. There are many kinds of refractory materials, and I basically understand all petrochemical refractory.

Q: how about the performance of aluminum silicate fire proof thermal insulation?: aluminum silicate fire proof thermal insulation board has a good performance. it is a artificial board that separates the wood and plant fiber by mechanical and chemical methods and mixed the adhesion agent and water-proofing?agent, molding by high temperature and high press. MDF(medium density fibre board) structure is more even than natural wood. it avoids rot, moth-eaten and other problems, while medium density fiber board has small expansion and contraction, which is easy to be processed. Since the surface of medium density fibre board is smooth, the board is easy to paste a variety of finishings, which makes furniture more beautiful. A variety of decorative wood-based panel is to embellish their homes.

Q: What's the function of aluminium dihydrogen phosphate on the refractories?: Mainly used for binder of high-temperature furnace refractory. Characteristics of liquid aluminum dihydrogen phosphate, castable. solid used for refractory spraying coating, chamotte, ceramic construction, which has high break resistance after being dried in 350-500 ° C, phosphate bricks. Characteristics of the solid aluminum dihydrogen phosphate, binding agent used for castable and casting industry: together with the refractory aggregate, ramming mixes at room temperature: Easy to mix, crush resistance, hydration resistance, chamotte, will not become soft even if soaked or boiling in water, molding. Liquid use refractory spraying coating, mainly used for corundum, chrome corundum water gap in refractory industry. The production of chrome aluminum zirconium corundum brick for water-coal-slurry gasifier is especially suitable for site construction applications mainly used for the electrical industry, high-temperature kiln and furnace, hardener, after mixing between 90-110 ° C for 4-24 hours at a constant temperature, forming strong bonding strength, electrical insulation, heat treatment resistance furnace

Q: As for fireproofing material rock wool and glass wool, which one is better?: As for fireproofing effect, the effect of rock wool is certainly better than glass wool , the highest temperature of rock wool is 1100 ℃, but the temperature of glass wool is only 600 ℃. In addition, if it's used in the external walls, then,unit weight of the glass wool is limited,and high unit weight can only be 60-90, but unit weight of rock wool can reach over 140, now external wall can't use glass wool, and only rock wool is A class fireproofing material. glass wool has lower thermal conductivity, rock wool has longer fiber length,as for the price, tons price of glass wool is more expensive than rock wool, but if it's acculated by square, square price of glass wool is cheaper than rock wool.

Q: Does the refractory material used in steelmaking all refer to refractory brick?: The refractory material used in steel making doesn't all refer to refractory brick, but also includes refractory castable. The foaming?agent, ladle filler sand and deoxidizer are not refractory materials but ferrous metallurgy auxiliary materials.

Q: What substitutes are available for high-end refractories in addition to zircon sand?: Natural ore, synthetic raw materials such as industrial synthetic mullite, etc..

Q: Which are roofing fireproofing material?: (1) Foamed concrete is a kind of fire-proof thermal inuslation matertial featured by good fire resistance and thermal insulation. Besides, it is also characterized by excellent sound proofing, penetration resistance, easy construction, safety and environmental protection without toxin and pollution. (2) Foam glass is featured by light weight, small heat conductivity coefficient and water absorbption, non-inflammability, fire resistance, high strength, no moulding, corrosion resistance, non-toxin and stable physical and chemical properties and thus widely used petroleum, chemical engineering and underground construction. It is also featured by thermal insualtion, heat/cold preservation and sound absorbption and thus can be used for thermal insulation of external wall and roof of civil builduing. Foam glass is featured by stable chemical property, easy to be processed and not easy to deforme, and durable. (3) With slag, basalt and other natural ore as the main raw material, rock wool, mineral wool and its products are made by high temperature melting into fiber, and then processing with binder. It has low thermal conductivity, fire resistance, easy construction and good effects of energy saving and thus is highly cost-effective. (4) With phenolic foam material as main material, phenolic resin plate is made by foaming thermoset phenolic resin. It is featured by light weight, fire resistance, no burning in the air, no smoking, non-toxin, no dropping and non-embrittlement and thus is an ideal thermal insulation material used in HAVC projects. Due to its high obturator formamen rate, low heat conductivity coefficient, good thermal insulation, water resistance and water vapor permeability, phenolic foam is an ideal thermal insulation material.
