- Q: what grades are fire resistance of fireproofing glass divided into?
- Fire resistance of fireproofing glass is generally divided into three levels, class A glass can satisfy the requirements of fire resistance and thermal insulation at the same time. Class B, it's a kind of fireproofing glass that can satisfy the requirements of fire resistance and heat radiation strength at the same time. Class C can satisfy the requirements of refractory integrity, if you want to know more specific requirements, you can also surf the internet for a more detailed description.
- Q: The mechanism and function of antioxidants in carbon containing composite refractories are briefly described.
- With the advantages of carbon refractories especially excellent slag resistance and high heat stability, but graphite under high temperature oxidation, in order to improve the oxidation resistance of carbon composite refractory materials, often adding a small amount of antioxidants, to improve the oxidation resistance of carbon composite refractories. Antioxidant additives commonly used in metal powder, silicon powder, magnesium powder, silicon carbide powder and so on.
- Q: What is the principal part of silicious refractory material
- Shenzhen Longgang Jiangyou Hua Boiler Accessories Co., Ltd. is specialized in refractory cement, refractory mortar, refractory clay, refractory aggregate and perlite. And other refractory | thermal insulation material, it has cooperated projects in Shenzhen, Huizhou, Dongguan, Guangzhou, Foshan, Zhuhai and other sites. For more information you can find our website on Baidu.
- Q: who knows the requirements of refractory for forge furnace?
- Here is the requirements of refractory for forge furnace: according to the chemical properties,casting fireproof materials are divided into three major categories: acidic, neutral and alkaline refractory materials. alkaline and neutral refractory materials are commonly used, such as alkaline magnesia-carbon bricks and burned magnesite bricks, magnesite-chrome bricks, magnesium-calcium brick, neutral high alumina brick, corundum brick, clay brick, etc., shapelessness materials include: castable refractory, ramming?mass, gunning mix, coating, dry vibrating materials and so on! Hope my answer can help you.
- Q: What are the insulation fireproofing materials?
- Insulated shoes, insulated gloves, tape (cloth, plastic, as well as waterproof) yellow wax tube, mouth care, fireproof (ie asbestos cloth is sold by jin) there is pressure-caps black tape, waterproof tape ,casing. There are glass fiber needle felt is widely used in electrical, chemical, construction, transportation, automotive and other industries interlayer insulation and silencer system, and used as an insulating fireproof material.
- Q: What are the chemical composition of refractory cement?
- Calcium aluminate prepared by calcining as the main component. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. Refractory cement is also known as aluminate cement.
- Q: What are fire?ratings of wall thermal insulation material?
- Grade A material has no ignition and is material with thermal insulation effect, anti-combustion material. Currently it mainly refers to inorganic thermal insulation mortars of vitrified micro bead, hole-closed?expanded perlite, rock wool,mineral wool,glass wool,cement base or gypsum base, inorganic thermal insulation mortars and self thermal insulation system of lightweight block. Grade B1 is nonflammable thermal insulation material, which is determined by fire endurance of this material. In addition, the division of the material of different parts is different! What is commonly seen, such as EPS / XPS insulation boards adding flame retardant through special treatment. Grade B2 is combustible thermal insulation materials, and what is commonly seen is EPS expanding polystyrene board and XPS extruded polystyrene board, that is, the general board. This material has low ignition point, and releases large amounts of harmful gases in the combustion process . Grade B3 is flammable insulation material. Thermal insulation material with polyphenyl foam as main material is commonly seen. Since this material is highly flammable, it has been eliminated external wall thermal insulation materials.
- Q: The principle of choosing fire-resistant material in Thermal Energy and Power Engineering equipment.
- Different thermal technology equipment has different operation condition and select different refractory material. We should take economical and practical as principle.
- Q: Who knows the fire endurance of B-level fireproof doors and windows?
- Rock wool board of B-grade fireproof doors keeps 46mm in thickness, doors that are generally used in relatively common fire fighting access, while A-grade fireproof doors are generally used in machine rooms, warehouses, oil depots and other important fire fighting access and flammable and combustible pulbic places. B-grade fireproof doors are more widely used than A-grade fireproof doors.
- Q: Can anyone tell me what is the material of which the mould for refractory is made？
- I can make the mould and give you a discount. If necessary, you can contact me at 261240643 (qq).
