- Q: What is the fire endurance of ceramsite concrete blocks?
- The fire endurance of 240mm thick ceramsite concrete blocks is 2.9 hours. It is made by adding pottery into fine aggregate, using cement as binding material, by mechanical mixing, molding machinery and natural protection. Ceramsite building blocks are used as wall material, which can reduce workers' labour intensity. It saves work and material. There is no empty drum during rendering. It is not easy to produce fissure. It has sound insulation, good thermal insulation performance, and is convenient to decorate. Nails, expaned setscrew and no wood anvil can be directly hit into wall. Moreover, It has high firmness.
- Q: What are the qualifications of refractory industry?
- Special qualification issued by Fire department
- Q: Concrete composition and function of magnesia bond used in refractory
- Mainly high purity magnesia powder and silica fume, in accordance with the 4:1 ratio of the mixture, that is, we often use in the castable MgO-SiO2-H2O binding system! Compared with cement, the content of CaO is lower, the high temperature strength of the product is increased, and the slag corrosion resistance of the product is increased!
- Q: How to make fire resistant materials for building stoves
- Why Qianjun game protected mode can attack the foreign baby call
- Q: The difference between refractory and thermal insulation material
- In simple terms, refractoriness is different. The refractoriness of refractory is high while that of insulation material is low.
- Q: how to divided the external wall thermal insulation materials fire rating
- The external wall thermal insulation materials is divided by fire rating: 1. The thermal insulation material of level A combustion performance: inorganic fiber spray coating, glass wool, foam glass, foamed ceramics, rock wool, foam cement and hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
- Q: What is the concept of lightweight refractory material?
- Lightweight refractory material has high porosity, mechanical strength and erosion resistance. Compared with normal refractory bricks, it is a kind of refractory material with large volume shrinkage in high temperature, low thermal conductivity and small bulk density. It is used as thermal insulation material in industrial furnace and other thermal equipments. It has poor wear resistancel.
- Q: What kind of material is refractory bauxite?
- Refractory bauxite, also known as bauxite alumina or bauxite with high alumina, is the main raw material for the production of high alumina (aluminum content ≥48%, belongs to LAS) refractory.
- 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: Who can tell me the properties and classification of insulating refractories?
- Bubble method. This method is the foam agent in a frothing machine mixing with water and prepared uniform fine foam, the foam added in common mud mixing into the foam slurry injection model, together with the drying, demoulding, at 1320 DEG C to 1380 DEG C (high alumina insulating refractory brick for burning) after processing, the plastic products.
