Q:What are the requirements of refractory temperature of refractory brick?
Refractory bricks furnace pipe material is generally divided into two types, namely, shapeless refractory material and shaped refractory. Shapeless refractory material, also known as castable refractory, is hybrid powder material made up of many kinds of aggregate or aggregate and a kind of or many kinds of binders. It must cooperate and evenly stir with a kind or many kinds of liquids during use and has strong mobility. Shaped refractory material usually refers to refractory brick whose shape has standard rules. It can also be processed temporarily during cutting according to requirement. Refractory brick, called refractory brick for short, is refractory material made by firing refractory clay or other refractory raw materials. Faint yellow or brownish, it is mainly used in building smelting furnace. It can resist 1,580 ℃-1,770 ℃ high temperature.
Q:What are the types of advanced refractory?
Divided into ordinary and special refractory two categories. Common refractories by chemical properties into acidic, neutral and alkaline. Special refractory are divided by the high temperature oxide, refractory compounds and high-temperature composite materials by its compositions. according to refractoriness it can be divided into ordinary refractory products (1580 ~ 1770 ℃), advanced refractory products (1770 ~ 2000 ℃) and premium refractory products (2000 ℃ above). The article can be divided into blocks (standard bricks, shaped bricks, etc.), special shape (crucible, sagger, pipe, etc.), fibrous (aluminosilicate, zirconia and boron carbide quality, etc.) and irregular shape (refractory clay, pouring materials and ramming mixes, etc.) According to the sintering process is divided into sintered products, cast products, melt blown products. The appearance is shaped or amorphous according to pH it can be divided into acidic, neutral and alkalinity according to basic operation mode, there are castable refractory ramming spraying materials, impressionable plastic material, coating. according to different components, there are clay, high alumina, corundum, spinel, magnesia, magnesium, calcium, magnesium aluminum quality,magnesia-chrome, silicon, etc.
Q:What are the commonly used fire protection materials
Firewall. The fire wall is made of non combustible material, and is directly installed on the base of the building or the reinforced concrete frame or fire proof walls . Fireproof limit of the firewall, according to the current "building regulations", is 4 hours, wheras the specification of Technical specification for concrete structures of tall building is 3 hours. doors resistant to fire, heat in a certain period of time These door usually prevent the spread of fire and gas in the fire resistant wall, staircase, pipe well. Fire door can be divided into steel fire doors, wood fire doors and composite materials fire door according to the material used. According to the limit of fire resistance can be divided into the class A fire door (1.2h), B fire doors (0.9), class C fire door (0.6h); (3) fire window. Windows resistant to fire, heat in a certain period of time It is usually installed in the fire resistance wall or doors; the fire shutter. This roller shutter can be refractory in a certain period of time. It is typically used for heat and fire insulation in escalator with difficulties to install fire resistant wall, fire resistant valve and smoke resistant valve. Fire resistant valve is installed in the ventilation and air conditioning system of air supply and return air duct, usually in the open state, fire, It will be turn off when the pipeline gas temperature reached 70 degrees, can meet the requirement for fire resistance and insulation for gas and fire. Smoke fire resistant damper installed in the exhaust system pipe, when the pipeline gas temperature reached 280 degrees, it will close automatically, insulating fire and gas.
Q:Which kind of external wall fire barrier zone material is better?
I recommended foam cement and particulate thermal insulation composite waterproof material, which is fire isolation area product, which uses surface of vertical?plate arranged fiber technology to make the compressive?strength in the vertical direction up to above 80KPa. At the same time, under the conditions of both exterior heat insulation and effects of humiture in the long-term, it can still maintain the non-aging performance of various aspects, and safety (reliability), fire resistance and excellent durability.
Q:What's the fire endurance of A grade fireproof glass curtain wall?
The following is fire endurance of A class fireproof glass curtain wall. Fire endurance of the fire window: A class fire window: no less than 1.2h; B class fire window: no less than 0.9h; C class fire window: no less than 0.6h. Technical requirements: 1. Materials and fittings: (1) Window frame should adopt the steel frame or wood frame with certain strength so as to guarantee the integrality and stability of the fitting; (2) Steel frame and mound layer can choose the galvanized steel sheet or stainless steel sheet. Its selection standard is in line with provisions of Article 5.1 in GB12955 "General Technical Requirements on Steel Fire Doors"; (3) Selection standard of wood frame and mound layer should be consistent with the provisions of Article 5.1.1 in GB14101 "General Technical Requirements on Wood Fire Doors"; (4) Filler material inside the steel frame and wood frame should be incombustible material; (5) Fireproof glass can choose the qualified product with no influence on the fire resistance test of the fire window, and its light transmittance should be no less than 75% of that of the ordinary sheet glass with the same layers; (6) Sealing material between the frame and the fireproof glass should use flame retardant material which can play the role of fire prevention and smoke insulation in case of fire.

Q:How long usually will the A-level fireproof materials prevent the flame?
A-level fireproof materials refer to the materials which are made of non-combustible materials, it is a different concept from fire resistance. non-combustible elements: Components are made of non-combustible materials. Non-combustible materials refer to materials that will not burst into flame, and burn as well as be carbonized when affected by fire and high temperature in the air. Fire resistance: Having a fire resistance test on any building components -----according to the standard time-temperature curve. This period starts from the time when affected by fire and ends up with losing the ability to support or to insulate fire or the integrity of the components. It can be expressed in hours.
