- Q: I wanna ask that magnesium oxide is refractory?
- Yes, Magnesia belongs to ionic crystals, the oin of magnesium has two charge, oxygen and magnesium ions are relatively small radius, these two factors make a lot of magnesium oxide lattice energy, high melting point is up to 2800 degrees Celsius. Because the magnesium oxide is stable and not react with water, it is widely used as a refractory material.
- Q: How to detect the acid resistance of refractory? Is there any standard? Thank you
- There is a standard. However, the range what you said is a little big, it's difficult for me to say. But though the scope is a bit big, it should be: You can check the industry standard network, to see whether you can check it.
- Q: how about the performance of aluminum silicate fire proof thermal insulation?
- aluminum silicate refractory fiber board has following characteristics:1. the structure is more even than natural wood. it avoids rot, moth-eaten and other problems, 2. fiber board has small expansion and contraction, which is easy to be processed. 3. its smooth surface is easy to paste a variety of finishings and you can make furniture more beautiful. Decorative wood-based panel is to embellish their homes. I hope it is useful to you!
- 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: Which schools are the best schools in the world for learning knowledge about refractories?
- Wish it helps you out.
- Q: The performance of refractory material
- The mechanical properties of refractory material include withstand voltage strength. The structure properties of the refractory materials include porosity, bulk density, such as thermal emission rate. The physical properties of the refractory materials include temperature conductivity structure performance, wear resistance, hiphotos, electrical conductivity, creep, the hydration resistance, adhesive strength.
- Q: What 's the highest temperature can magnesium plate glass resist ?
- 2 hours, according to the fire resistance test report, 2h
- Q: Who knows the fire endurance of B-level fireproof doors and windows?
- According to the fire endurance, fireproof doors can be divided into A-grade, B-grade and C-grade, whose fire endurance should not be less 1.2h, 0.9h and 0.6h respectively. Fire endurance of fireproof windows: A-grade fireproof windows are not less than 1.5h and B-grade fireproof windows are not less than 1h. The door leaves of A-grade and B-grade fireproof windows should be steel materials, and their glass should be composite fireproof glass whose thickness is no less than 26mm. Monolithic fireproof glass window is not B-grade fireproof window, nor A-grade fireproof glass window. It si called non-insulated fireproof window.
- Q: What are the specifications of fireclay bricks?
- Dimensions of refractory bricks : 230 * 115 * 65mm
- Q: How to divide fire resistant level of fire door?
- The classification of fire resistant level of fire door: Grade A is not less than 1.2h. Grade B is not less than 0.9h. Grade C is not less than 0.6h. It is suitable for fire door with different levels: Grade A: Equipment room (such as fire-pump room,power distribution room, generator room, smoke control fan room, etc) door, fire?compartment, door on firewall; Grade B: Eclosed staircase, front door of stair room, smoke-proof?staircase and fire elevator share lobby door, front door of fire elevator, household door which directly opens to front room or shares room; Grade C: The vertical shaft door, such as strong electric wells, weak electric wells, pipe shaft door and air conditioning facilities. I hope this information can help you.
