- Q:What's the fire resistance test method of doors and roller shutters?
- Fire resistance test method of doors and roller shutters: This standard specifies the fire resistance test method for roller shutter doors under standard fire conditions. The method is used to test the fire resistance of the ventilating duct when bearing the external fire (A duct) and internal fire (B duct). Fire resistance test of vertical ducts may be conducted referring to this standard. 1.Test specimen1.1 The test specimen is obtained by cutting from any part of the qualified metal tube unless otherwise relevant standard or mutual agreement specifies the cutting position of the metal tube. 1.2 Length of the specimen: L≈2.5D+50mm (D: outer diameter of the metal tube). The cut surface of the specimen must be perpendicular to the axis of the metal , and the seamed edge of the cut should be round off. Test method GB243-82 of metal tube necking 2. Test procedures 2.1 In the test, punch or press the metal tube into the tapered conical seat (see Figure) with a hammer or press machine, and make it uniformly diminished to the regulated shrinkage X which is calculated according to the following formula: Test method GB243-822 for metallic pipe necking: The inner wall of the seat cover used in the test should be polished, and has certain hardness and is coated with lubricating oil. Its conicity is 1:10, 1:5 or others in accordance with relevant standard provisions. If there is no provision, then adopt the conicity of 1:10. This standard is not suitable for: a) The pipeline whose fire resistance depends on the fire resistance of the ceiling; b) The pipeline with access door, unless otherwise the access door is included into the pipeline and tested together; c) The pipeline with two or three sides; d) Fume exhaust pipes;
- Q:Does the aluminum silicate thermal insulation material fireproof?
- it can be fireproof and has a strong fireproof?performance.
- Q:How much is the duration of fire resistance of the porous brick shale?
- This is really a simple question. The temperature should be limited within 1050℃, or it will be scorched. I think 980℃would be acceptable.
- Q:What is the function of refractory in ceramics?
- Refractory is used as materials of kiln,sagger and kiln car for ceramic sintering. Its refractoriness is higher than ceramics, and the essential material and tool for ceramic sintering.
- Q:How to distinguish between class A fire resistant door and class B fire resistant door from appearance ? What are the differences between the two refractories? Thank you !
- It is difficult to distinguish from appearance. Their fire endurance are also different. The filling refractories of grade A and Grade B fire resistance steel doors are all perlite. The only difference lies in the filler compaction density.
- Q:How to choose the material of refractory?
- Long using temperature of aluminum oxide fiber is 1400 ℃, containing chromium aluminum silicate fiber, quartz, high purity aluminum silicate fiber, long-term use of temperature is 1000-1200 ℃ has aluminum silicate refractory fiber according to different raw materials, advanced refractory fiber (such as alumina. Commonly used vitreous aluminum silicate refractory fibre is amorphous, zirconium oxide refractory fibre) using temperature is 1700 ℃ view as >and the best temperature is 1300 ℃. Crystalline refractory fiber are polycrystalline mullite fiber, including ordinary aluminum silicate fiber, alumina and graphite refractory fiber, etc. The use of common refractory fiber temperature is 1150 ℃;>
- Q:What are the applications of refractory in petroleum?
- It can be used in chemical filler. For general process, some insulation parts also need to use refractory.
- Q:What's the fire endurance of A grade fireproof glass curtain wall?
- An hour and a half, an hour, and half an hour. As a key step in the home fire prevention, fire door is particularly important. According to the fire endurance and heat insulation performance, it can be classified as follows: A class fire door with fire endurance of no less than 1.5h; B class fire door with fire endurance of no less than 1h; C class fire door with fire endurance of no less than 0.5h. We can choose according to different needs, while A class fire door and B class fire door are now commonly used. Fire door has great varieties, and the material it uses is also of wide range. It includes stainless steel fire doors, glass fire doors, steel fire doors, etc. The most important feature of fire door is its fire resistance period. The main difference between A class fire door and B class fire door lies in their fire endurance, of which the former is no less than 1.5h, while the latter is no less than 1h. Difference between A class fire door and B class fire door also lies in their fireproofing material. That is the thickness of the built-in fire prevention board, of which A class fire door is 52mm, while B class fire door is 46mm. Therefore A class fire door obtains longer fire resistance period than that of B class fire door and gains better fireproof performance. A class fire door and B class fire door also differ in the places they are used. A class fire door is generally used in important fire fighting access of machine rooms, warehouses and oil depots, etc. and flammable and explosive public places, while B class fire door is generally used in the ordinary fire fighting access of some ordinary buildings. But B class fire door is more widely used than A class fire door.
- Q:what's the standard of fireproofing material?
- first, the classification of fire resistant levels of buildings, 1, the classification basis of fire resistant levels of buildings, the classification of fire resistant levels of buildings is one of the basic building fire protection technology measures, our national architectural design specification divides fire resistant levels of buildings into first, second, third and fourth class, first class ios the highest and has the most strong fire-resistant capacity, fourth class is the lowest and has the weakest fire-resistant capacity. Fire resistant level of buildings depends on the combustion performance and fire endurance of the components of the buildings. construction components refer to the wall, base, beam, column, floor, stair, suspended ceiling and other basic components of buildings. Combustion performance and fire endurance of building components are shown in table 4-11), the combustion performance of building components are divided into non-combustible component,hard-comnustible component,combustible?component,according to their response to the fire. as for building components, non-combustible component includes wall column and base,etc; hard-comnustible component includes hanging?bracket, suspended ceiling and internal pipe;combustible?component includes doors and windows, suspended ceiling, decoration materials,etc.
- Q:Can anyone say something about what A-level fire-proof decorative material is?
- Now A-level market is very confusing. The major products are material monomer A-level and composite A-level, now a lot of B-level material is wrapped in calcium silicate board. The foam cement overall composite is level A, such as phenolic aldehyde composite, as well as some of the foam paddings, while monomer A-level includes rock wool, ultra-thin insulation panel and the like.. But there are few products with real sound A level qualification. Many manufacturers are playing the edge ball with A-level fire rating examining reports and B-level system detection reports and records, but this situation will not last long, which will soon be clear. I hope the information above can help you. Hope you adopt
