- Q:Why do magnesium oxide refractory bricks can be made into refractories?
- 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:what's the classification of fireproof and thermal inuslation matertial?
- 1. thermal insulation material with A class combustion performance. Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite (2) thermal insulation material with B class combustion performance: extruded polystyrene board after special processing (XPS)/ polyurethane after special processing (PU) , phenolic aldehyde, gelatine powder polyphenyl granule. 3,thermal insulation material with B2 class combustion performance: molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane (PU), polyethylene (PE),etc. sea capacity module and vitrified micro bead(cooperate with the innovator of vitrified micro bead, Liu Weihua) fireproofing issues have been completely solved.
- Q:Is there vermiculite in refractory?
- Vermiculite is usually used as lightweight material in refractory field, and its volume density is about 0.5.
- Q:What kind of refractory materials are used in the intermediate frequency furnace?The domestic boric acid can be used as a lining?, how much is the rate?
- The variety of refractory materials for intermediate frequency furnace is mainly made of aluminum and silicon, both shaped and unshaped refractory materials are available. I have no ideas what you said boric acid, I’ve never seen that boric acid was used as an additive.
- Q:Is the refractory reached British BS standard and used for cables in China at present ceramic silicone rubber?
- The texture should be designed according to the British relevant BS standard; crosslinked polyethylene or ethylene propylene rubber under 6600V to 19000 / 33000V is not necessarily ceramic silicone. The rated voltages of a small amount of smoke and corrosive gases from 3800 & # 47 when the BS 7835-2000 is affected by fire.
- Q:Can anyone say something about the curtain wall fire-proof material key sealing point?
- When sealing the gaps between glass?curtain?wall and floors of all layers and the outer edge of the partition with rock wool or mineral wool, its thickness should not be less than 100mm and should be filled densely; Rock wool or mineral wool for horizontal smoke prevention zone between floors should use galvanized steel sheet whose thickness is not less than 1.5mm to support; The gaps between supporting plate, major structure, curtain wall structure and supporting plate should be filled with fire-resistant glass, whose fire endurance should meet the design requirements. Fire-resistant glass for curtain wall are mainly include monolithic fire-resistant glass as well as the hollow glass and laminated glass made by monolithic fire-resistant glass.
- Q:How to divide the fire resistant level of construction thermal insulation materials?
- How to divide the fire resistant level of construction thermal insulation materials: Combining three versions of GB8624 (1997,2006,2011) external wall thermal insulation fire?rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. There are many technical indexes for specific division, very professional and technical, so it is hard to say clear now. For details, please contact Qingdao Shanfang Instrument Company who is specialized in fire?rating tester for external wall thermal insulation materials.
- 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.
- Q:Who can introduce the external wall thermal insulation materials fire rating regulations?
- 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:Can I use ordinary cement with the addition of sand, clay, and salt as refractory material to paste the stove?
- You can add some hair, sand, yellow mud and some salt, but don’t use cement, it would lead to a thermal explosion.
