- Q: who knows the fire resistant levels of fireproofing glass?
- According to the fire resistance levels, it can be divided into three categories: Class A: a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. Including composite flameproof?glass and perfusion type fireproofing glass . This kind of glass has the properiyies of transmittance, fireproofing ( smoke insulation, fireproofing, and keeping out thermal radiation), sound insulation, shock resistance, and it's suitable for steel and wooden fire door of building decoration, windows, varnishing, partition walldaylighting?roof,ceiling?screen,perspective floor and other construction components demading for transparency and fireproofing. Class B: Marine fireproofing glass, including porthole fireproofing glass and rectangular window fireproofing glass, surface glass pane is tempered safety glass, the inner surface glass pane material can be arbitrary selection. Class C: it's a kind of monolithic fireproofing glass that only satisfies the requirements of refractory integrity. This kind of glass has characteristics of transmittance, fireproofing, smoke insulation and high strength,etc. It's suitable for fireproofing glass partition wall, fire Windows, outside curtain wall and other places without insulation requirements.
- 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: What is the difference in the nature between the refractory material and thermal?insulation?material
- thermal?insulation?material is a material which has a strong impedance to the heat flow. the nature of the material requires that the material can isolate the delivery of thermal, and the low heat conductivity coefficient and expansion coefficient of the non-metal material.refractory is good in heat resisitance and chamical erosion but not high temperature resistance. Requirements on nature is still in high temperature.
- Q: Is there requirement for radiation indicator in refractory?
- All refractories have no radiated harm to environment, so there is no requirement. From the elemental analysis, magnesite. I do not know it is helpful to you. But for refractory rwa material, any chemical element is radiated, including silicon?dioxide; If they are radioactive. From the use analysis, such as bauxite, do not have use value.
- Q: What needs to be noted when choosing and using blast furnace fireproof materials? Who knows?
- there are different temperatures in various parts of the blast furnace, thus using different types of refractory.
- Q: How is the performance of refractory materials?
- It is a little difficult to answer. There are some requirement for refractory materials, such as fire resistance, softness, creep, thermal shock, abrasive resistance. Besides, requirements for construction performance include: Liquidity, plasticity and other linear change rate, volume density, strength (including high temperature) and all other important indicators must be tested the same conditions with the use of test conditions and test items like body density, strength, line changes in the basic project
- Q: What are the differences between intensive refractory busway and other busways?
- Compact busway is named according to its structure, and fire-resistant busway is named after its uses. Compact busway especially refers to busway which is closely laminated between phases and between phase and shell, and use thin insulating material to achieve the insulation result. Suitable for power supply system of alternating current three-phase four-wire, three-phase five-wire system, frequency of 50 ~ 60Hz, rated voltage up to 690V, rated operational current of 250 ~ 5000A, as auxiliary equipment for mining, enterprises and high-rise buildings, and especially suitable for the transformation of workshop and old enterprises. Fire-resistant busway is composed of shell coated with fire retardant paint, bus line wrapped with fire-resistant mica tape and bracket made by refractory insulating material. Bracket has a plurality of grooves where inbedding the bus line and fixed it. There is a busway connecting box at one end of the busway and there is a bus line splitter box in the busway. Fire-resistant busway has excellent insulation properties, which can not only be used continuously in a normal environment, but also can be used in the fire environment continuously for more than one hour, suitable for high-rise buildings and important facilities.
- Q: Why should graphitic refractory materials be used now that graphite can burn?
- C is inactive in nature. Carbon will not burn unless the temperature is about 2000℃, so it can't be lit generally. Coal can be lit because it contains other combustible substance which ignite carbon indirectly. While graphite, carbon black, is more pure and dense than coal., so it is hard to oxidize.Their molecular structures are also different, just like diamond is harder than graphite.
- Q: how does the fire endurance of first rate fire resistant window?
- class A window not less than 1.5 hours, class B window not less than 1 hours, Class C window not less than 0.5 hours.
- Q: Classification of porosities in refractories and their effects on properties
- The pores in refractory include open pores, through pores and closed pores.
