Q: Who knows about roof fireproofing materials?: Roof thermal insulation materials are various which generally can be divided into two categories, namely inorganic and organic materials: Inorganic materials are expanded perlite, aerated concrete, rock wool, glass wool, etc. Organic materials are styrofoam, polyurethane?foaming?plastic and so on. A. common roof thermal insulation materials 1. the expanding polystyrene board (EPS) has good thermal insulation performance, and cheap price but poor intensity with heat conductivity coefficient of 0.038-0.041. 2. extruded polystyrene board (XPS) has better thermal insulation performance and high intensity but an expensive price with heat conductivity coefficient of 0.028-0.03. It is moisture resistant but needs treatments on surface in construction. 3. rock wool board, with heat conductivity coefficient of 0.041-0.045, is fireproofing, fire?retardant. It has a good hygroscopicity performance but is poor in thermal insulation. 4. gelatine powder polyphenyl granule heat insulating slurry, with heat conductivity coefficient of 0.057- 0.06, has a good flame resistance performance, but the results of recycling and thermal insulation are unsatisfactory. It has high construction requirements. 5. polyurethane foaming material, with heat conductivity coefficient of 0.025-0.028, has good waterproofness and thermal insulation performance, as well as high intensity, but it is expensive. 6. perlite and other slurry, with heat conductivity coefficient of 0.07-0.09, have good flameproofness and water-absorbing ability but are poor in thermal insulation and thermostability.

Q: What's the fire?retardant material of roller shutter fire resistance door ?: Fire resistant rolling shutter door is generally filled with aluminum silicate fiber cotton inside.

Q: How long is the fire-fighting time of A class fire resisting window?: Duration of fire resistance of fire resisting window: A class window is not less than 1.2 hours; B class window is not less than 0.9 hours and C class window is not less than 0.6 hours. Technical Requirements: 1materials and accessories (1) window frame structure adopts stell framework and wooden framework that have a certain strength to ensure integrity and stability. (2) steel framework and batten can choose galvanized steel plate or stainless steel The selection criteria meet requirements of GB12955 steel fire door general technical conditions in the provisions of article 5.1. The selection criteria of wooden framework and batten meet requirements of GB14101 wooden fire door general technical conditions in the provisions of article 5.1.1. Filling material of steel and wooden framework shouldn't adopt non-combustibility material. (5) fire-fighting glass can adopt testing-qualified product that don't influence fire resistance performance of fire resisting window. Light transmittance of glass is not less than 75% of the same layer common plate glass. (6) Sealing material between framework and fire-fighting glass should adopt Flame retardant material which can serve as fire-fighting and smoke-resistant when encounter fire disaster. (7) hardware fitting should accessories product that is tested to be qualified. 二. installation requirement: 1. When Party A takes over goods, he should check numbers, specification, grades and whether Accessories are Conformed and complete according to contract.

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 to classify the grade of wall fireproof and thermal inuslation matertial?: The level classification of wall fireproof and thermal inuslation matertial: Grade A: incombustible building material: Material almost with no combustion. Grade B1: nonflammable building material: Nonflammable material has good flame resistance. It is difficult to fire in case of fire in the air or at high temperature. It is not easy to quickly spread. After the fire source is removed, combustion stops immediately. Grade B2: combustible?building?material: Combustible materials have a certain flame resistance. It will immediately burst into flames in case of fire in the air or at high temperature and is easy to lead to the spread of fire, such as wooden column, timber roof truss, timber beam, wooden stairs, etc. Grade B3: Flammable building material: It has no flame-retardant effect and is highly flammable. Fire hazard is very large.

Q: What are fireproofing materials?: Plants often use the fireproof sealing material with steel structures without much modification. All the panels that meet the first-order fire protection requirements can be fireproofing materials. Like gypsum boards, aluminum sheets and so on. . Coatings are usually those with fine powder, high density and good sealing. Hardeners mainly depends on specific requirements. .

Q: How to prolong the furnace age of Induction furnace by using fireproof materials?: magnesia solid materials have thermal endurance and erosion/ performance and its change of temperature is likely to cause cracks. properties of materials (aluminum) in such case have to be taken into consideration.

Q: Is the refractory reached British BS standard and used for cables in China at present ceramic silicone rubber?: The texture should be designed according to the British relevant BS standard; crosslinked polyethylene or ethylene propylene rubber under 6600V to 19000 / 33000V is not necessarily ceramic silicone. The rated voltages of a small amount of smoke and corrosive gases from 3800 & # 47 when the BS 7835-2000 is affected by fire.

Q: Who knows the fire endurance of rock wool color plate?: Colored steel rock wool board is used for areas with high fireproofing requirements. Colored steel rock wool board belongs to class A according to "Fireproof? Specification of Building Interior Decoration?Design" whose lifetime can reach more than 15 years, operating temperature can up to about 700 ℃, maximum fireproofing time is 6 hours. And rock wool colored plate is environmentally friendly materials, which is is the preferred material in the construction industry .

Q: Where is the development of refractory industry?: The rapid development of continuous casting technology of its related @ China @4 honing refractories develop and increase in variety and quality, continuous development of refractories for the continuous casting billet continuous casting production and quality have a significant impact. Especially, the completion and operation of Baosteel have greatly promoted the technological progress of refractory materials in China, and the refractory materials for continuous casting have made great progress both in variety and in quality.
