FACTORY:
- Q: Can anyone tell me the requirements of the refractory masonry?？
- Refractory materials actually have two functions. The first one is to improve the refractoriness and the second one is to improve the body plasticity of refractory materials.The higher the aluminum content is, the better refractory it will be. Of course, the content of aluminum in refractory materials can not be impoved only by using kaolin. Such raw materials that contain more aluminum as bauxite chamotte should be used as framework.So the content of aluminum in kaolin does not need to be too high and more than 38% of aluminum is enough. However, the viscosity should be taken into account. It will be better if the viscosity is better as the extra bentonite do not need to be added.The refractoriness that is is above 1400 degree is enough.
- Q: I wanna ask about the building insulation materials fire rating?
- Hello, I am happy to answer your questions about the classification of building insulation materials fire rating: 1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, 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: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. I hope I can help you
- Q: how about the performance of aluminum silicate fire proof thermal insulation?
- aluminum silicate fire proof thermal insulation board has a good performance. it is a artificial board that separates the wood and plant fiber by mechanical and chemical methods and mixed the adhesion agent and water-proofing?agent, molding by high temperature and high press. the density of fiber. tha above information is coming from the Internet and it is just for reference.
- Q: How long is the duration of fire resistance of hollow glass magnesium board
- Glass magnesium board is non-combustible board with excellent fire resistance ability, the continuous burning time of flame is 0, non-combustible at 800℃, no flame at 1200℃, achieving the highest level of fire retardant level A1; Partition System cooperated with high-quality keel can endure fire for more than 3 hours. In the process of combustion, a large amount of heat energy can be absorbed, and the temperature of the surrounding environment will be delayed.
- Q: How to choose refractory material
- Refractory fiber according to different raw materials, there are aluminum silicate, quartz, alumina and graphite, refractory fiber. Commonly used aluminosilicate refractory glass fiber is amorphous, including ordinary aluminum silicate fiber, high-purity aluminum silicate fiber, chromium silicate fiber, long-term use temperature of 1000-1200 degrees.
- Q: Who can introduce the external wall thermal insulation materials fire rating regulations?
- According to public fire-fighting [2007] No. 182, the contents of the notification on the implementation of a number of issues of national standards GB8624-2006 "building materials and products combustion performance classification", since there is large differences between the new version of the standard GB8624-2006 and the old version of GB8624-1997 in the principle, hierarchical structure and test methods. According to the cintent of notification, in order to ensure a smooth transition between the old and new standards, the current national standard "Fireproof? Specification of Building Interior Decoration?Design" GB50222, "fire?safety?rules of tall civil buildings design" GB50045, "Fireproof? Specification of Building Design" GB50016 have not completed the relevant amendments, the new classification method of GB8624-1997 and GB8624-2006 can be used for temporary reference in terms of combustion performance of materials . From GB8624-2006 standard implementation, the classification of combustion performance is too granular, which do not match to the actual construction of the current project in our country. Therefore, the relevant departments carry on the 3rd amendment for the GB8624-2006 standards, namely GB8624-2012, and it will be released on December 31, 2012 and implemented on October 1, 2013. The combustion grading requirements in the standard: Level A is non-combustible materials (products); level B1 is nonflammable material (products); level B2 is combustible materials (products); level B3 is flammable materials (products).
- Q: What is refractory aggregate?
- Refractory aggregate is fire-resistant product improved with low temperature binder, chemical?compound and normal temperature strength.
- Q: What parts of cement kilns are refractories used on?
- Generally they are used in cyclone, feed pipe, and duct and refractories are high-strength alkali-resistant castable, calcium silicate board, high-strength alkali-resistant brick, dome-shaped alkali resistant brick. Refractories in smoke chamber are high-alumina refractory castable, anti-skinning pouring material and calcium silicate board. Refractories in duct are high-strength alkali-resistant bricks, calcium silicate boards and steel fiber reinforced castable. Refractories in hooding parts of kiln are high strength castable high alumina and calcium silicate board. Refractories in rotary kiln are phosphate bonded high alumina brick, silmo brick, magnesia chrome brick, steel fiber reinforced castable. Refractories in grate?cooler are vault alkali brick, high alumina refractory castable, steel fiber reinforced castable and calcium silicate board. Refractory in coal burner is dedicated castable for coal burner.
- Q: What are the refractories for converter?
- Magnesia carbon material with large surface repair vessel, in addition to supporting the use of magnesia and magnesia cement.
