Q: I wanna ask what are the acidic refractories?
Usually, acidic refractory refers to a kind of refractory which contains a amount of silicon?dioxide. There are the following: (1) silica?brick with stronge acidity, unshaped silicious refractory, quartz glass and fused silica combined products; (2) semi-silica refractory with moderate acidity and pyrophyllite refractory; (3) clay-based refractory with weak acidity. The main features of the acidic refractories is resistant to the erosion of acidic substances (acidic residue) in high temperature, but is easy to react with alkaline material (basic slag). zirconite fireproofing material and silicon carbide as the special acidic refractories refractories are also in this category.
Q: What is required to do refractory material?
What kind of refractory material? It’s too extensive.
Q: What is the main material of fireproof wooden door?
Fireproof door is an important part of fire-fighting apparatus and society fire prevention, so the quality and use of fireproof door is the key to the success of the fire prevention. Some customers don't know clearly that whether the fireproof door should install a door closer. Today I specially read the explanation of relevant state departments for fireproof door, in the explanation in 5.3.3, fireproof door should be installed fireproof door closer or set, so that normally open fireproof door can automatically close close-door device of the door leaf (except for the use of special parts, such as pipe shaft doors, etc.) in the event of a fire. In other words, except for some special parts which don't need to be installed door?closer, such as pipe shaft doors, other parts are required to install fireproof door closer.
Q: What is the limit of fireproof rolling shutter?
Fireproof rolling shutter door is a kind of fire protection and heat insulation facility which is suitable for the large openings of buildings, having a certain effect on the design and installation. Fire shutter doors are widely used in fire partition of industrial and civil building. It can effectively prevent the spread of fire, to protect the safety of life and property. It is an indispensable modern building fire facilities. According to the national standard 14102-2005 GB standard, the provisions of 14102-2005 GB specify that: 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.
