Q:How long is the duration of fire resistance of hollow glass magnesium board
It belongs to second level refractory building. The fire resistance limit of prestressed hollow slab is 0.7 hours, according to provision 3.2.7 and 5.1.5 of fire safety rules. When reaching 20 thick protective layer, the fire resistance limit of the prestressed hollow slab is 0.7 hours. When reaching 30 thick protective layer, the limit of the fire resistance of prestressed hollow plate is 0.85 hours. Protection layer of prestressed hollow board prefabrication is 15, plaster ceiling has 12 protection layers, the total protection layer amounts 27, which can achieve fire resistance limit of not less than 0.75 hour.
Q:How many types of special refractories are there?
Metal ceramics, high temperature coatings, high temperature fiber and other reinforced materials
Q:Preparation of refractory clay
Is it to make refractories? Add some andalusite to the refractory mortar will improve the effect.
Q:What refractories have good mechanical property resistance and heat expansion and cold contraction property?
Explain that where you use it for and what requirements you have. Follow-up: I use it in metallurgical furnaces with the features of strong stirring and acidic residue.
Q:How is the fire endurance of the fireproof paint?
second level firerpoof of cooling rack. with a fire endurance from 1 to 1.5 hours. According to the code for fire protection design of buildings. 1. fireproof grading of first level is 1.5 hours 2, fireproof grading of second level is 1.0hour.
Q:What is the limit of fireproof rolling shutter?
According to the national standard 14102-2005 GB standard, the provisions of 14102-2005 GB specify that: According to provision 14102-2005 GB: If fire resistance limit of fire resisting shutter is no less than 3 hours, it is AAA fireproof rolling shutter. Therefore, the fire resistance limit of AAA grade fireproof rolling shutter should be 3 hours.
Q:Can polystyrene foam color steel plate be used as decorative fireproofing material ?
No, only non-combustible product can prevent fire. Most polystyrene foam boards are flammable which cannot prevent fire. Polyphenyl can only retard flame, highest fire retardant fire rating being B1 level. Under the same conditions, fireproof performance of polystyrene foam board will be better because most extruded sheets are made by recycling materials and contain much more impurities which will affect flame resisting property. The second reason is that high temperature in extruded sheet manufacturing technique will decompose part of flame retardants. For B1 level extruded sheet, it is difficult to reach 30 burning oxygen index, while for B2 level, it is hard to reach 32. So polyphenyl board is safer.
Q:What are the construction fire-proof materials?
1. fire retardant coating 2. fireproof panel 3. fire proof and sealing material 4. flame resisting decorative materials 5. Green fire prevention materials
Q:Who can tell me what is neutral refractory?
It is a material that can resist acidic and basic slag, flux and chemical erosion form other refractories at high temperatures. The main components include carbon, silicon carbide, aluminum oxide, chromium oxide and other trivalent oxides, such as carbon refractories and chrome refractories, etc. Strictly speaking, neutral refractories refer only to the carbonaceous refractories, including carbon brick and graphite silicon carbide products, etc. Sometimes, high alumina refractories with high Al2O3 content also belong to this material, such as some materials that are acidic but tend to be basic refractories, like sillimanite, mullite bricks and corundum bricks. Recently developed aluminum carbon bricks, zirconium carbon bricks alumina - silicon carbide - carbon bricks, silicon nitride bonded silicon carbide brick and so on are also neutral refractories. This material can be used in the bottom of blast furnace, the lining of hearth and bosh, and the lining of aluminum electrolytic cell, calcium carbide furnace, ferroalloy furnace, molten steel ladle, plating tank, reaction tank, and autoclave and so on.
Q:What types does refractory floor include?
There are many types refractory bricks, including silicon aluminum refractory brick, the leading product in refractory bricks. And its high temperature resistance can reach up to 600 degree centigrade or more, so it is an excellent refractory brick. And this high-alumina refractory brick is very suitable for metal industry for its strong practicability. Another one is alkaline series refractory brick, including magnesite refractory brick, and these two bricks are good materials resistant to high temperature.
