- Q: who knows the fire resistant levels of fireproofing glass?
- Fireproofing glass is a kind of special glass which can keep its integrity and thermal insulation performance in regular insulating refractory trials. and it can be divided into three classes according to its fire resistance: Class A, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. 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, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. Such kind of fireproofing glasses mostly are composite fireproofing glasses and has characteristics of transmittance,fireproofing and smoke insulation. Class C, it's a kind of 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. Classify from the structure,fireproofing glass can be divided into composite fireproofing glass and monolithic fireproofing glass.

- Q: What is the function of refractory material?
- Refractory is a basic material in the field of high temperature technology. Generally, the refractory is used as structural material or lining to resist high temperature in various thermal equipment and high temperature container. In the iron and steel industry and metallurgy industry, coke ovens are mainly composed of refractory materials. Various refractories that meet the requirements are essential in blast furnace for ironmaking, hot stove, all kinds of steel-making furnaces, soaking furnace and heating furnace. Not only the die casting for molten steel needs lots of refractory materials, but also the continuous casting needs some high-quality refractory materials. Without high-quality refractory materials, external refining is also not impossible to achieve. Statistics show that the steel industry is the sector that needs the most refractory. Pyrometallurgy and thermal processing of ferrous metal also needs refractories. All high-temperature furnaces or lining in construction materials industry or other high temperature industries that produce silicate products such as glass industry, cement industry, and ceramics industry must be constructed with refractory materials. All kinds of roasting funaces, sintering funaces, heating furnaces, boilers, flues, chimneys and protective layers in chemical, power and machinery manufacturing industry need refractories. In short, when some kind of structures, devices, equipments or vessels are used under high temperature, they all should utilize refractory to resist the high temperature because those materials will deform, soften and fuse or will be eroded, scoured or broken due to the physical, chemical, mechanical effects, which may stop the operation, affect the production, contaminate processed objects and impact the quality of products.
- Q: Which industry does refractory belong to?
- It belongs to construction industry.
- Q: What does the function of SiC for refractories?
- Silicon carbide for machine non-metallic materials with high temperature wear characteristics of silicon nitride bonded silicon carbide ceramic cups and other products in a blast furnace ladle brick aluminum silicon carbide as an antioxidant added MgO-C
- Q: Who knows about the grade C fireproof door materials?
- There are no differences in the interior materials of the grade A , B and C fire doors, they all use fire?rock?wool?boards. The only difference is the thickness of built-in fire rock wool boards. The rock wool boards' thickness of grade A fire doors is 52 mm, that of grade B is 46mm, and that of grade C is 40 mm.
- Q: What are the materials used in refractory material processing?
- Refractory materials generally refer to inorganic non-metallic materials with a refractoriness of more than 1580 degrees. It includes natural ore and a variety of products made by a certain process according to certain requirements. It has certain high temperature mechanical properties and good volume stability. It is the necessary material for all kinds of high temperature equipment. Ordinary refractories are often used brick, semisilica brick, clay brick, high alumina brick, magnesia brick etc..
- Q: What are the requirements on fire resistance period of C-level fireproof glass?
- What are the requirements on fire resistance period of Class C fireproof glass? The fireproof glass is a special glass which can maintain its integrity and insulation in required fire resistance tests, it can be classified into three types: Class A the fireproof glass which meet demands of fire integrity, and fire insulation at the same time. This glass has advantages of excellent transmittance, fire-proofing(smoke resistance, fire insulation, and blocking heat radiation), sound insulation and impact resistance. It can be applied to architectural ornaments, fire resistant timber doorsets with steel structure, windows, upper beam, partition walls, daylighting roofs, ceiling screens, perspective floor and other building components which need transparency and fireproofing. Class B: The fireproof glass which meets demands of fire integrity and thermal radiation intensity at the same time. This glass is mostly composite fireproof glass which has advantages of transmittance, fireproofing, and smoke resistance. Class C: The fireproof glass which only meets demand of fire integrity. This glass has advantages of transmittance, fireproofing, smoke resistance and high intensity. It can be applied to fireproof glass partition walls, fire windows and with no requirements on outdoor curtain walls, etc. The fireproof glass can be classified as composite fireproof glass and single chip fire-proof glass in terms of structure.
