White Fused Alumina GOOD QUALITY Made in China

Q: Who can tell me what is neutral refractory?: Refractories mainly refer to aluminum oxide, chromium oxide and carbon as the main component of refractory materials, such as corundum brick, high alumina brick, and carbon brick. Its characteristic goes to the resistance to both acidic and basic slag. Basic refractories mainly refer to the refractory materials whose mian components are magnesium oxide and calcium oxide, including magnesia bricks, magnesia-alumina bricks, magnesia chrome bricks, dolomite bricks, etc. Basic refractory is good at resisting basic slag erosion.

Q: I wanna ask about the building insulation materials fire rating?: Hello, I am happy to answer your questions about the classification of building insulation materials fire rating: 1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3 combustion performance is level B2 insulation material: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. I hope I can help you

Q: What are the standards of refractory concrete ?: Heat-resistant concrete refers to the kind of concrete which remain undamaged, do not lose the necessary bearing capacity at 200 ~ 1300 ℃ high temperature for long term, and still maintain its physical and mechanical properties.

Q: What is the most reasonable drying heating curve of magnesia refractories? Products of less than 0.5T: o

Q: what is the common materials for home fireproofing material?: 1, lumber core 2,decoration panel 3 , plywood 4 density board 5,chipboard 6 fireproof?panel, 7.gypsum board Hope to adopt my opinion

Q: what's the varieties of thermal insulation material with A level fire?rating?: the main A level fireproof material is rock wool now (note:it is rock wool not mineral wool). A1 level fireproofing, now the largest producer is Taishi rock wool Co., Ltd.; hope my answer can help you, thank you.

Q: What is the fireproofing requirements of external wall thermal insulation materials?: External wall thermal insulation materials fire rating regulations, 1, the height of a building is greater than or equal to 100m , the combustion performance of insulation materials should be level A; 2, the height of a building is greater than or equal to 60m but less than 100m, the combustion performance of insulation materials should not be less than the level B2. When using level B2 thermal insulation material, every layer should set horizontal fire barrier zone 3,The height of building is be equal or greater than 24m but less than 60m, the combustion performance of thermal insulation material should not be less than the level B2. When using level B2 insulation material, each two-layer should set fire barrier zone ; 4, the height of building is less than 24m, the combustion performance of insulation materials should not be less than the level B2. Besides, when using level B2 thermal insulation material, each three-layer should set a horizontal fire barrier zone.

Q: What is fire retardant coating mainly used for?: The functions of refractory coating are as follows: 1. Non-intumescent fire retardant coating is mainly used for the fireproofing of wood, fiber board and other materials, and it is used in the surfaces of wood truss, roof, doors, windows and etc. Second, the intumescent fire retardant coating can be divided into non-toxic intumescent fire retardant coating, expansible fire retardant coating emulsions, solvent-based fire retardant coating. 3. Non-toxic intumescent fire retardant coating can be used to protect cables, polyethylene pipes and insulation board. 4, The expansible fire retardant coating emulsion and solvent-based fire retardant coating can be used for fireproofing of buildings, electricity power, and cables. 5. New fire retardant coating: Transparent fire retardant coating, water-soluble intumescent fire retardant coating, fireproof emulsion paint, polyvinyl acetate emulsion fire retardant paint, water-soluble intumescent fire retardant paint drying at room temperature, fire insulation coating polyolefin fire retardant coating, modified high chloropolyethylene fire retardant paint, chlorinated rubber fire retardant coating, firewall coating, intumescent coatings, wire and cable fire retardant paint, new fire retardant coating, casting fire retardant coating and so on.

Q: what is steel fire door made of ?: 1. fire resistance steel door has steel made door frames, door leaf framework and door panels. if the door leaf is filled with nontoxic fire insulation material, added with fireproof hardware accessories, which consists of a door that is fire resistance. This is a steel door.
