- Q: what's the fireproof levels of fireproof and thermal inuslation matertial?
- 1, organic materials: B level material is flammable, B1 level material is flame retardant. 2, inorganic materials: Grade A flame-resistant materials are divided into three classes and two kinds of materials.
- Q: I wanna ask you, which level is b1 fireproof and thermal inuslation matertial ??
- which level is b1 fireproof and thermal inuslation matertial: I soppose you mean rubber and plastic! Only rubber and plastic has b1b2 level. Level b1 is the fireproofing level b1, because the rubber and plastic does not belong to the fireproofing material. It only has fire?retardant. The wholesale of all kinds of thermal insulation material and construction needs to look at the name.
- Q: What kind of materials can be tested their electrical resistivity in the current refractory industry?
- Graphite, Magnesium Oxide, and alumina are all feasible.
- Q: How to determine the fire resistance rating of the aluminium-plastic?panel?
- Fire rating of the best aluminium-plastic?panel in the current market is B1 class, and its grade classifications can refer to the national standard. I have examined factories and tested the fireproof effect of the fire-proof plate myself by burning it, and I have found that the fire-proof plate of Jinwei Aluminium-plastic?Panel in Linyi is really good in quality and fire prevention. In other words, from the single point of fire rating, the corresponding fire rating of the called fireproof aluminum (plastic) composite panel should be at least B class, and for A2 class fireproof aluminum composite panel, its core material currently doesn't include plastic element, so it's called aluminum composite panel which is of inorganic core material. If the ordinary aluminum-plastic panel is classified according to the fire-proof building material, it will belong to that of lower level. For aluminum-pastic panel used in business premises, it is required to reach the grade of flame retardant material or above this in fire prevention. It is expressly stipulated that its fire rating should be A2 class in public places.
- 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: What is the acceptance standard of refractory?
- It depends on the variety of materials. In general the main test items include chemical composition, refractoriness, refractoriness under load, creep, volume density, linear change, strength, slag resistance, thermal conductivity and thermal expansion. If it is shaped products, it is required to inspect the size deviation and whether it has edge. Detection method accords with the relevant national standards and there are lots of them. You can refer to the standard compilation.
- Q: Can you tell me the classification of fireproof sealing material.
- Fire blocking is to use fire blocking material as partition between cable threading hole and electric hole. Its role is to prevent the cable itself catacausis or outside naked light make the fire spread to achieve the purpose of protecting the safety of personnel and equipment. The principle of fire-proof sealing is plugging material acting as bloating heat absorption and heat insulation. Fireproof sealing material in current market include: fire-proof sealing plate, foam sealing materials, flame retardant module, flexible organic plugging material, inorganic fire sealant, plugging and fire package, etc. The wide usage of fire-proof sealing material in building construction can ensure the fire flame and high temperature flue gas not to extend another fire partition tendril.
- Q: What does refractory mean?
- Basic refractory material generally refers to Magnesium Oxide or Magnesium Oxide and calcium oxide as the main component of refractory materials. This kind of refractory material has higher refractoriness and strong resistance to alkaline slag.
- Q: Does anyone know about the A-level fireproof materials?
- A1-level fireproof materials include: 1. inorganic materials: glass wool, rock wool, foam glass,etc. 2. organic materials: phenolic foam insulation composite board. I hope my answer can help you.
- Q: Firing high temperature kiln of refractory and internal temperature being as high as 1600 ℃, metal heat exchanger can't use, how to do?
- Directly using silicon molybdenum kiln, the temperature is better. Now using the electricity is cheaper than the price of other fuels.
