Q: How long can gypsum board endure fire?
Fire endurance refers to the fire-resistent limit of the whole system of light-gauge steel structure coupled with gypsum. It does nor merely refers to gypsum board. Fire endurance of the common gypsum board with the thickness of 9.5mm keeps 1.5 hours. Those gypsum board with the thickness of 12mm has a fire endurance of 3 hours.
Q: Is fireclay corrosive?
No. All of the refractory materials have stable chemical properties and their usability can be guaranteed under high temperatures.
Q: How is the division of the fire resistant level of the rock wool board?
The fire rating of European style rock wool board is level A , which uses Da Guang Beijing Jinyu rock wool board, with the main advantages are: 1, High acidity coefficient: The high coefficient of acidity greatly improves the life resistance and weather resistance of the rock wool board. 2, Hydrophobic air permeability: According to the picture, Jinyu Star rock wool is water-repellent, at the same time it also has breathability, so the liquid water is not easy to dip into the rock wool, and the water vapor and other gas molecules could pass through the rock wool. In particular, the insulation materials have this feature which enables the building to have "respiratory function" thus making the room more comfortable and preventing anti-mildew phenomenon happening indoor. 3, Environmental protection: The goldfish can survive freely, which just shows it is environmental; 4, High strength: The advanced pleating and curing technology make the rock wool board tensile and high compressive strength. It not only can be applied on the external wall thermal insulation and sandwich board core material, but also can be used to make structural cotton in the flexible waterproof roofing. Its quality is so stable that it is convenient in construction and durable in use. 5, Fireproofing: Not just talking about the fire rating, but the fireproofing time, which is generally up to two hours, and can be used for lining thermal insulation fire-resistant part of the glass curtain wall, through-wall pipe seal, pier?between?two?windows, window sill wall and other parts; 6, Derived advantages: Agriculture applies the soilless cultivation cotton;
Q: what is the original materials of fireproof coating?
Main raw material includes high-temperature aluminum surface, expanded vermiculite,closed cell perlite, high mark number cement, Fireproof paint itself is flame-retardant or non-combustible, protecting the substrate from direct contact with the air,delaying the time for catching fire and reducing the burning speed. For example, indoor thick fire retardant coating for steel structure.
Q: Who knows which chrome refractories produced by the Henan refractory plant can be used for continuous casting?
The sand is used as the filling material for the bottom of the ladle. Zhengzhou real iron refractory Co., Ltd. is specialized in the production of non-ferrous industries. All kinds of refractory materials used in glass kilns and cement kilns are sold directly by manufacturers. The prices are reasonable.
Q: Manganese steel belongs to refractories
Material wear and other harsh working conditions, extrusion, there will be work-hardening phenomenon rapidly on the surface. The most important feature of manganese steel is that it is not refractory under a strong impact, and under extrusion conditions, part of it will be fractured. The main form of damage is wear and consumption: It is a kind of inorganic non-metallic material whose refractoriness is not lower than 1580 ℃, mainly used to endure impact. Manganese steel is a kind of high strength steel, which is free of deformation, so that it can remain austenite good toughness and ductility at heart while keeping good wear resistance at the same time on hardened layer. Refractories are
Q: what should be paid sttention when buying the refractory?
solve the resources and the cost as much as possible. Accurate understanding and knowing the material temperature changes of various partsin order to choose the appropriate refractories. 4: 3, work performance, for example, take measures to ensure the overall life, and it is a very good buying principles: melting in high temperature metal erosion. These are the four major problems to consider when using refractory. You can choose low prices and low transportation costs of materials to meet the basic principles under the conditions described above. 2.carefully observe the material to prevent the desturction and reducing the costs. according to the structure of furnace, reasonable coordination of all parts of the material, fully take the advantages of material characteristics and strive to develop the recycle, to avoid the destruction of the materials.1. the working characteristics and the sport condition and analyze the reason of destroying the material, which can not only gurantee the product quality and reduce the expenses, get familiar with the chemical component and physics of the material.
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: How many levels are there in the classification of PP fireproof materials?
The level of fireproof materials: A-level: Non-combustible building materials have rare chance to burn. A1-level: Non-combustible materials, no open fire A2-level: Non-combustible materials, smoke should be tested and qualified. 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 are highly flammable with no flame retardant ability, fire risk is high.
