Q: What is the role of adding chromium oxide green in unshaped refractory materials: Generally, less is added in corundum or corundum spinel refractory material, but it can significantly improve the material performance such as high temperature strength, erosion resistance, thermal and shock stability, etc.

Q: what is the requirements of roofing insulation materials fire rating?: The fireproofing requirements of architectural design are regulated by architectural design fire?safety?rules, roofing insulation material only has the requirements of materials combustion performance, namely non-combustible material. No fire rating requirements.

Q: What are the fire resistance ratings of the glass partition?: The glass partition system is composed entirely of metal structures, glass, color plate and other materials which also has fire resistance capacity. When the inner structure of the system is steel structure, the fire resistance of which is 30 mins, 60mins or even longer. The fireproof glass is a special glass which is able to maintain its integrity and insulation in a fire resistance test. According to fire resistance performance, it can be divided into three categories: Class A: The fireproof glass which meets 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.

Q: Fire rating of decoration materials: All light steel keel gypsum board is considered level A; if the wood finishes up to B2 grade fire rating depends on the proportion of the use of wood veneer and the proportion of this wood veneer fire grade, if the proportion of wood veneer is small,it can be considered level A

Q: Which kind of external wall fire barrier zone material is better?: I recommended foam cement and particulate thermal insulation composite waterproof material, which is fire isolation area product, which uses surface of vertical?plate arranged fiber technology to make the compressive?strength in the vertical direction up to above 80KPa. At the same time, under the conditions of both exterior heat insulation and effects of humiture in the long-term, it can still maintain the non-aging performance of various aspects, and safety (reliability), fire resistance and excellent durability.

Q: Which one is the best refractory material?: Resin bonded refractory is mainly abot aluminum magnesium carbon, and carbonaceous etc. Thermoplastic resins need to add the coagulant (Uto), ageing mixture for a period of time, so the production cycle is long. Hot hard resin is relatively not so complex, but it’s not as good as thermoplastic resins in thermoplastic binding.

Q: what are the types of piping insulation material fire?rating?: Pipe insulation material Fire rating: heat conductivity coefficient(at room temperature) 0.025 grade non-combustible Class A low temperature bending ≤ 5000 breaking elongation 5,000 specifications 5000 anti-bending?strength 5000 compressive?strength 5000 special brand of high use temperature -250 ~ 150 ℃ core material, phenolic foam, form, stratiform, shape,flake.

Q: What kinds of refractory materials that can resist 3,000 Celsius degree?: I think that graphite is the only one.

Q: How do refractory materials apply into pyrophyllite?: Generally speaking, shaped refractory materials require of some powdery materials like spray grouts and iron trough in addition to pyrophyllite brick made of a mixture of pyrophyllite aggregate and powers.
