- Q: How to use fire-resistant soil?
- It can live with water, not too sticky. Don't be too thin. It's best to put the stove in the inner wall.
- Q: The primary problem, does the gas permeable brick is fired refractory bricks(refractory) ?
- Yes. After moulding by casting in the firing of 1450 ° degrees.
- Q: Where is the sizing nozzle for refractories? Just enter the line, master into!
- Hua Heng refractories in the industry reputation is good, especially in the Southern small steel sales are among the best!
- Q: What are the features of construction class A fire resistant door ?
- Residential building: If the building height exceeds 100 meters, the combustion performance of thermal insulation material should be A level. Other civil building: Class A fireproofing material MCM should be set in buildings whose height is above 50 meters. National A level fireproof flexible?material is made up of soil, rock flour, sand, cement and other inorganic powder and modifying agent. Product density is 2327kg / m3. Upon examination, the combustion performance of the product meets A level requirements, and the additional classification meets s2, d0, t0 requirements. According to GB 8624-2006 sepcification, combustion performance of the product should reach A2-s2, d0, t0 level. Light, thin: 2-4mm thick / piece, saving space and cement, convenient to transport. : State Class A fireproof flexible?material. Freezing-thaw resistance: up to 100 freezing-thaw experiments (close to 100 years), the surface has no powder, no crack and no peeling. Aging and acid resistance: anti-aging property can reach more than 3500h, that is, it will not degenerate for 50 years. Recyclable: new energy, renewable , no "three wastes" emission
- Q: What is the concept of lightweight refractory material?
- Lightweight refractory material has high porosity, mechanical strength and erosion resistance. Compared with normal refractory bricks, it is a kind of refractory material with large volume shrinkage in high temperature, low thermal conductivity and small bulk density. It is used as thermal insulation material in industrial furnace and other thermal equipments. It has poor wear resistancel.
- Q: What crusher is used for raw material of broken refractory material? What is the rough crushing process? What are the materials? Thank you!
- Now cone crusher is generally used.
- Q: What is neutral refractory? Can refractory suppliers tell the main components of it?
- The material using Al2O3, clay, bauxite and corundum as the main components is neutral material; the material using MgO and CaO as the main components is basic material; the material using SiO2 as th emain component is acidic material.
- Q: Could you tell me how does fire protection standard of decorative material is divided?
- Divided by plate material: structure material, base layel materials and fabric; Divided by fire protecrtion type: easy to burn, difficult to burn, flame retardant, incombustible material. Material has no fire rating, only the different from the time of combustion limit. Building fire protection. Building fire protection is the fire prevention measures of buildings. In the architectural design, fire protection measures should be taken to prevent fires and reduce fire hazards to life and property. Building fire prevention measures includs prophylaxis before the fire and measures during the fires. The former is mainly to determine the fire resistance rating and fire-proof structure, control fuel quantity and space easy to fire site; The latter mainly for fire partition, setting of evacuation and smoke, fire-fighting equipment, etc. In ancient China, flammable wood are usually taken as a building material, which has accumulated many experiences for the building fire protection .
- Q: What is the quote of fireproof and soundproof materials used in KTV?
- 1. fire retardant, sound absorbing sheet,eggs,pyramid,sound-absorbing material, piano room, studio, KTV, with glue on the rear, 15 Yuan 2. bar, KTV, fireproof sound insulation cotton, sound-absorbing materials, studio, eggs, drum practice room, sound-absorbing and sound insulation materials, pyramid, 25 Yuan 3. fireproof wood excelsior absorbent, sound absorbing board, wall ceiling decoration materials, materials, theater, KTV, wood color fiberboard, 30 Yuan.
- Q: what textures of furnace refractories are good?
- The common one uses the ordinary aluminous fireclay brick and GB / T 3994-2005 insulating fireclay brick. The ones with excellet texture are high-grade thermal insulation refractory brick and GB / T 3995-2006 high alumina insulating firebrick, whose model is A13, the texture is alumina, A13 50u, advanced heat insulating brick B5; intermediate heat insulating brick B2, and so on. Dolomite brick: The formation of coating is of good performance and corrosion resistance, but to some extent, there exsits the f-CaO in the brick, which is easy to hydrate, and hard to transport and storage, thus less using in the production. Magnesia-chrome brick: The formation of coating is good, so it is widely used for burning zone, but the disadvantage is poor thermal shock resistance, coupled with the highly toxic positive Hexavalent Cr, so the international countries that produce and use the magnesia-chrome bricks are gradually reducing. The production unit using this brick now, please find alternatives as soon as possible.
