Q:Can anyone tell me what material the first rate fire resistant door is?
Material of Class A fire doors can be divided into steel and wood, so fire doors can be divided into fireproof steel door and fireproof wooden door. In fact, fire doors of all classes are divided into steel, wood, steel and wood, and other materials (see GB ). Mainly depending on what kind of material the customers want. The fire door is called class A fire door not because of the material but because of the fire-resistant time. The fire resistant time of class A fire door is not less than 1.2 hours and fire doors as long as meeting this condition can be called class A fire doors . The filling material in class A fire doors is generally perlite, whose difference is in thickness. A few of them will use fireproofing materials like foam core board, vermiculite fireproof board, MC composite material and so on. The thickness of class A fire door is usually 50mm. I hope my answer can help you.
Q:which kind of refractory is commonly used in the industry
Therefore it is known as special fire-resistant materials, such as yttria, high alumina raw material (sometimes neutral), olivine,which is used for alkalinity furnace, dolomite, and we roughly divided into several categories, beryllia, cerium oxide, these materials have a strong alkaline slag resistance, thorium oxide, lime, serpentine, which is picked from these refractory raw materials. the raw materials of basic refractory materials are mainly magnesia clay and titanium oxide, but because not many sources of raw materials, it can not be widely applied in the refractory industry, and we can analyze which kind of materal is processed by the pulverizer. There are many kinds of refractory materials, rotary?kiln can only be used in particular circumstances. These materials have a variety of slag resistance at different degrees. the main material of special refractories is zirconium oxide. the refractory clay is the most basic and most widely used raw material in the refractory industry.
Q:What are the construction measures of refractory material in winter? Please descriptive briefly.
Binding agent should be attaced great importance to when construction is conducted in winter. Generally if the bingding agent is water or cement, antifreezing measures should be taken.
Q:Who knows the fire rating of fire?partition with steel stud?
Partition system made by fire?partition with steel stud and high-quality keel has good fireproofing performance and is non-combustible sheet. Flame burn duration is zero. It does not burn at 800℃, and it is without flame at 1200℃. Its fire resistance rating reaches GB8624-A standard through test, which reaches the highest fireproofing and non-combustible level grade A1. 10MM fire endurance can reach up to 4 hours fire resistance maximum limit. It can absorb a lot of heat during the process of burning and delay the rise of temperature in surrounding environment.
Q:How to divide the fire rating standards of insulation materials?
1. According to the GB8624-97 national standard, building materials can be divided into following levels in terms of combustion performance. A-level: Non-combustible building materials: Materials almost don't burn. B1-level: Fire-retardant building materials: Fire-retardant materials are good at resisting flame. It is difficult for them to burst into fire when coming across open fire in the air or at high temperature. It will not quickly get wilder and when the fire source removes, it will be extinguished immediately. B2-level: Combustible building materials: Combustible building materials can play a certain role in preventing combustion. It will immediately burst into flames when coming across open fire or at high temperature, and will lead to fire spreading, such as wooden pillars, roof frames and beams as well as stairs. B3-level: Inflammable building materials: Inflammable building materials are highly flammable with no flame retardant ability. The fire risk is high. 2.The exterior wall thermal insulation materials can be classified according to fire rating. 1. Insulation materials with A-level combustion performance: rock wool, glass wool, foam glass, ceramic foam, foam cement, close-celled perlite, etc. 2. The insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), Phenolics, Polystyrene rubber powdery particles,etc. 3. Insulation materials with B2-level combustion performance: Expanded polystyrene sheets(EPS), Extruded polystyrene board(XPS), Polyurethane(PU), Polyethylene(PE), etc.
Q:How to choose thermal insulation materials for flood heating?
How to choose the appropriate thermal insulation materials: 1, Thermal insulation material shall have a small thermal conductivity, good thermal insulation properties. Besides, that also depends on whether the specific temperature changes of in the insulation materials' working environment can ensure the material has good thermal insulation. 2, when purchasing, we must be make sure it is light, and loose enough. These heat insulating material can not only afford bracket, and can also increase the heat transfer performance of the heat insulation material. prevet water penetration. Waterproof function should be soild, even if it accidentally absorbs water, its thermal insulation function must be guaranteed. 3, None of the organic material should applied to production of insulation materials, Thermal insulation material containing organic matter may get rotten, mildewed, and cause other destructive . At the same time they should not contain flammable substances, in order to avoid the fire. I hope my answer can help you
Q:what's the fireproof levels of fireproof and thermal inuslation matertial?
at present,thermal insulation and fireproofing materials on the market include inorganic thermal insulation bead board(Shanghai Benniao construction and energy saving decoration materials company) rock wool (Hebei Shenzhou glass wool products co., LTD.) foamed glass ceramic (Nanjing Institute of Building Research) or sogou search.
Q:It the Special Fire-Proof Material belonged to ceramics? Is there a national standard of the Special Fire-Proof Material?
The fiber and reinforcing material of the metal ceramic is also belonged to the Special Fire-Proof Material. ~~~~GB is too much trouble, GB online should ~~~ Lei Bao Refractories for you. The high temperature inorganic coating. 5. The refractory compound. 3. The high melting point oxide. You can search it on the internet according to the classification~~~~ The special refractories can be divided into five categories: 1. metal ceramic
Q:Who knows the classifications of magnesia refractory?
Magnesia chrome series products: The main ingredients of magnesium chromium series are MgO and Cr2O3. Periclase is the first phase and magnesia-chrome spinel is the second phase. Products belonging to this series are magnesium chrome brick and chrome magnesia brick. The main ingredients of magnesium aluminum series are MgO and Al203. As they generate MgO and Al203, all magnesium chromium series products contain magnesia material. magnesium calcium series products The main components are MgO and CaO. They have high melting points, which are important magnesia materials. 5, magnesium silicon series products: The main component of magnesite series is SiO2, when the C / S<5, SiO2 and MgO generate MgO.Al2O3 (forsterite). From the perspective of microscopic mineral, main products of pure aluminum series include magnesium aluminum brick, periclase spinel brick, corundum spinel brick and aluminum-spinel castable in unshaped materials. I hope this answer can help you.
Q:Who knows the new fireproof and thermal inuslation matertial?
New fireproof and thermal inuslation matertial: foam concrete building blocks brick. The foam concrete building blocks brick is a new fireproof and thermal insulation material, with distinct advantages compared with the organic insulation material . Foam concrete can be used as wall materials, and it has a good self-insulation properties, so there is no problem of dropping off the outer insulating layer. A small part takes external wall exterior insulation, with mostly anchoring or dry hanging, which are not easy to fall off. Very few uses paste. Since the foam concrete and wall materials are of the same nature and strong adhesive, so it is also not easy to fall off.
