Q:How long can gypsum board endure fire?
General gypsum plaster board with a thickness of less than 12mm has a fire endurance which is less than half an hour. It is clearly stipulated in Clause 2.0.4 of "Specification of Fire-resistance of Decoration Design in the Interior of Buildings" that "gypsum board, mineral wool board and acoustic board whose combustion performance reach at B1 grade installed on steel joists can be used as A-grade incombustible materials. Although the gypsum board is non-combustible material, we need to examine materials' stability in the face of fire and their fire retardant limits besides exmine their fire prevention standards. Fire retardant limit refers to the ability and time that materials can resist fire when encounting fire and taking palce changes.
Q:What's the organzational structure of refractory material?
Although hacing same chemical composition refractory material products also is mineral organizer. There are differences in the type of mineral phase, high refractoriness under load, quantity and crystalline state. The organizing minerals and microstructure are reflected by folding strength, high temperature pit definite density torsional strength, high-temperature torsional strength and product property. But, for example, wear or crack may cause damage. The performance index can reflect the internal structure of refractory: the nature of the thermal performance---linear expansion coeffcient. And the mineral composition of refractory material depends on the chemical composition and process conditions, the heat capacity and temperature conductivity. If the processing conditions are different, the influence of chemical action, and thermal conductivity: represents the nature of the mechanical properties - normal temperature, high temperature compression strength, high temperature creep performance and elastic modulus. Chemical compositions are the basic characteristics of refractory, representing the nature of the density---porosity, corrosion occurred refractory materials in high temperature use As a result, the composition and quantity directly determines the performance of refractory, true density: representing the forming of high temperature performance --- refractoriness, high temperature volume stability, so you can't analyze the effect on the product performance just from chemical composition. The performance of various refractory materials are different. It must be emphasized that macroscopic organization structure of refractory material is also an important factor that affects performance; reflecting complexity of penetration---air permeability, thermal shock resistance and slag resistance. The main component is the foundation of refractory characteristics.
Q:who knows the fire resistant levels of fireproofing glass?
Fireproofing glass is a kind of special glass which can keep its integrity and thermal insulation performance in regular insulating refractory trials. and it can be divided into three classes according to its fire resistance: Class A, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. This kind of glass has the properiyies of transmittance, fireproofing ( smoke insulation, fireproofing, and keeping out thermal radiation), sound insulation, shock resistance, and it's suitable for steel and wooden fire door of building decoration, windows, varnishing, partition walldaylighting roof,ceiling screen,perspective floor and other construction components demading for transparency and fireproofing. Class B, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. Such kind of fireproofing glasses mostly are composite fireproofing glasses and has characteristics of transmittance,fireproofing and smoke insulation. Class C, it's a kind of fireproofing glass that only satisfies the requirements of refractory integrity. This kind of glass has characteristics of transmittance, fireproofing, smoke insulation and high strength,etc. It's suitable for fireproofing glass partition wall, fire Windows, outside curtain wall and other places without insulation requirements. Classify from the structure,fireproofing glass can be divided into composite fireproofing glass and monolithic fireproofing glass.
Q:What requirements should refractory materials meet?
The operating temperature of forging furnace is above 1000, which can ensure the normal operation of the furnace, prolong the life of the furnace and save energy. General requirements for refractories are as follows. 1 They should deform at a sufficient temperature without melting. 2, They should have necessary structural strength without softening and deforming. The volume should be stable at high temperature without expansion, contraction or cracking. 4, They can resist erosion of molten metal, slag, gas and other chemicals.

Generally speaking, high fire resistance, non combustible Various standards for evaluation varies according to different types, which includes anti-corrosion, acid and alkali resistance, waterproof, anti termites and so on. I hope my answer can slove your problem
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 to distinguish the fire resistant level of construction materials?
Division of fire resistant level of building material: 1, It can be divided into five levels according to the importance: a, special class: commerative, historic, international and national buildings. b, Class A: high-grade residential architecture and public building. c, class B: middle-grade residential architecture and public building. d, class C: orinary residential architecture and public building. 2, It can be divided into four grades according to fireproof performance: Fire resistance level buildings is divided into four levels. Standard of fire resistant level is based on the combustion performance and fire endurance of main components of the house. 3, It can be divided into 4 levels according to durable life: a, A grade durable life, over 100 years, for important buildings and high-rise buildings. b, second level durable life, from 50 to 100 years, for ordinary buildings. c, third level durable life, from 25 to 50 years, for secondary buildings. D, fourth level durable life, less than15 years , for temporary buildings. I hope my answers will help you.

Q:Can polystyrene foam color steel plate be used as decorative fireproofing material ?
Polystyrene foam plastic can not be used as fireproofing material; polystyrene foam plastic is made up of polystyrene resin as main component, foaming agent and other additives. It is a buffer material which is most widely used[1]. It is closed hole structure, so it has low water-absorbing quality and excellent water resistance; low density, about 0.015 ~0.03; good mechanical strength, excellent buffer performance; good machinability, easy to be moulded; good dyeing property, thermal adaptability and anti-radiation; high dimensional accuracy, uniform structure. Therefore, it has a large share in external wall thermal insulation. But it will emit polluted styrene gas when burning. It is a kind of class B material in construction.
Q:How long is the fire endurance of Grade A fire resisting shutter
Fire door can be divided into Grade A, Grade B and Grade C fire door according to its fire endurance. Their fire endurance is not less than 1.20h, 0.90h and 0.60h respectively. Use fire resisting shutter as fire compartment separation in places where it is difficult to set firewall. When fire resisting shutter whose unexposed surface temperature rise is used as judging condition of fire endurance is used, its fire endurance should not be lower than 3h. When fire resisting shutter whose unexposed surface temperature rise is used as judging condition of fire endurance is not used, individual protection of  closed automatic water spray system shoule be set at two sides of the shutters and duration of water spray system should not be less than 3.0h.
