- 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:How to divide the fire rating standards of insulation materials?
- The fire rating classification standards of insulation materials, 1. Insulation materials with A-level combustion performance: inorganic fiber spraying, rock wool, glass wool, foam glass, ceramic foam, foam cement, close-celled perlite, etc. 2. Insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), Phenolics, Polystyrene rubber powder 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 is the high-temperature flame-retardant fibre board?
- high-temperature flame-retardant fibre board is good decorative material. Hope it helps you.
- Q:What materials is silicious thermal insulation board made of?
- Refractories that contain more than 93% of the monox are acidic refractory materials which include ordinary silica brick, high-density and high-purity silica brick, silica brick that contains chromium, fused quartz products, unburned brick and siliceous ramming materials. It has good softening temperature under a fixed load and can resist corrosion of acid slag, but will have chemical reaction with alkaline slag. Silicious refractory of industrial value mainly is crystalline quartz, such as α and β quartz, tridymite and cristobalite.
- Q:What are the specific steps of stirring the steel ladle castable?
- Steps are as follows. 1 Compulsory mixer is used to stir the castable and bags, rope and other debris can not mix in the castable when stirred. 2, Castable should be unpacked on the scene. Stirred volume depends on the capacity of the mixer. Castable should be accurately measured and put into a blender. 3 The process of first dry mixing and then wet mixing is adopted. After the castable is added to the mixer, it is dryly mixed for 2 minutes, add about 5.2 to 5.5 percent of water and continue to add water while stirring. Water that is 80% of the total should be added, and then decide whether to continue to add or not depending on the consistence (noting that the water must be clean water and sewage can not be used). Then it is wetly mixed for 4 minutes and stirred for not less than 6 minutes at one time, until castable is even. In general, the bottom is slightly dry and the wall of the ladle is slightly dilute (the amount of water is only for reference). 4, The amount of water and mixing time should be controlled strictly when stirred to ensure that the needs of the consistency are met. If castable is too thin, it will seriously affect the quality of the material. The stirred volume, stirring time and water that is added should be consistent and they can not suddenly be thick or suddenly be thin. If the consistency does not meet the requirements, the castable should be put back to the mixer and stirred with appropriate water or dry materials. 5, It should be stirred evenly and casting should finish in 20 minutes, in order to avoid sclerosis, affecting structural strength of ladle lining 6, After each completion of construction, varieties of castable should be changed and the mixer should be cleaned 7, Stirring can stop in halfway. If the mixer breaks down and it can be repaired in a short time, some of the materials have to be removed before the machine is opened. If the machine can be repaired on time, castable refractory should all be removed.
- Q:Is fireclay corrosive?
- No. All of the refractory materials have stable chemical properties and their usability can be guaranteed under high temperatures.
- Q:what kind of fireproof materials is used for high rise buildings?
- First, fire resistance steel door: in the general real estate, developer uses more of fire resistance steel door. The mid-low-end doors are the earliest products and mostly widely used with longer servce time. The disadvantages are corrosions, thus it will rust, fade after being used for a while, and will affect the overall appearance. Styling lines are hard, not matching well with modern home decorative styles. Second, the stainless steel fire doors: anti-theft performance ,durable, stronger security. Compared to the general iron or mixed iron and steel security doors, stainless steel doors never rust and most importantly its uniqueness in addition to lasting bright color. Disadvantages: Stainless steel security doors are mostly silver, giving us dull feelings by seeing its appearance and color, lack of coordination. Third, glass fire door: high quality fire glass doors. recent years have seen wide application in office buildings and some high end public place, less in individual users. Compared to the current categories of timber, fire glass door is not only simple and luxury and durable.
