Ceramic Fiber Blankets For Sale

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:Can anyone tell me what is A-leve fireproof material?: What you say is probably palstic! B-level means the fireproof rating is at B1-level because palstic material doesn't belong to fireproof materials. It only is fire?retardant. When wholesaling all kinds of insulation materials and construction, it need tos look at the names. B1-level refers to the fire endurance rating of the fireproof material, which is determined according to the fire resistance of the material. In addition, different parts of the material have different fire endurance ratings! You can download a "Specifications of Fireproof Design for Buildings" for further information!

Q:What kind of materials can be tested their electrical resistivity in the current refractory industry?: Graphite, Magnesium Oxide, and alumina are all feasible.

Q:Who can introduce the difference between galvanized fireproof?coatings and steel structure fireproof materials?: Steel structure with heat galvanization has a process requirement, which is to spray fireproof coatings. Fireproof coatings have different functions and purposes from galvanized process. When the steel surface derusted, it generally needs to brush rich-zinc primer before spraying fireproof coating. Fireproof coating plan itself includes anticorrosion plan, and fireproof coating is just a layer of coating plans, which is an intermediate layer in general. Fireproof coating plan generally includes primer, fireproof coating and finishing paint. Some fireproof coatings can be directly painted on the bare steel elements without primer and finishing paint.

Q:How to count the construction costs of refractories?: In winter, the temperature of the the fire-resistant masonry, fire-resistant plastic, sodium silicate, phosphoric?acid castable should be maintained above 5 ℃. Usually greenhouses in which heating facilities are installed to maintain the appropriate temperaturere for the construction environment should be erected in refractory masonry. The temperature around the construction site of the industrial furnace and refractory masonry shall not be lower than 5 ℃.

Q:Who knows what material is in the center of fireproof rolling curtain?: In fact, in general, the middle of fire roller shutter is fire prevention materials, filled with asbestos fire protection materials in the fire shutter door of the two layer of iron sheet. I hope my answer can help you

Q:Which are fireproofing external wall materials?: According to combustion performance, external wall thermal insulation materials are classified as Grade-A and Grade-B. Grade-A refers to incombustible material and Grade-B combustible material. A few years ago the fire in CCTV building and Shenyang Hotel were caused by Grade-B material. Currently Grade-A material is more commonly uesd and less expensive than Grade-B material. Grade-A material can be divided into thermal mortar, phenolic foam board, rock wool board, foam cement board, etc. Thermal mortar is easy for construction and unexpensive, but it is also easy for faking due tou its simple procesing. It is recommended to find a large factory whihc has gone through the formalities.

Q:Which basic refractory is better?: Zhengzhou Xindeyuan Refractories Co., Ltd.and Zhengzhou Rongsheng Kiln Refractories cO.,Ltd. Their basic refractories mainly refer to refractories with magnesium oxide and calcium oxide as main components what can resist errosion of basic slag, including magnesia bricks, magnesia-alumina bricks, magnesia-chrome bricks, dolomite?bricka and so on(magnesia bricks), among which magnesia bricks is the most common. Magnesia brick containing more than 80% to 85% magnesium oxide, has good resistance to basic slag and iron slag, and higher refractoriness than clay and silica brick. It is mainly used for open-hearth?furnace, oxygen-blown converter, electric furnace, ferrous metal smelting equipment and other high temperature equipments.

Q:Does refractory belong to metallurgical auxiliary materials?: Refractory includes metallurgical auxiliary materials.

Q:How many fire endurance grades are the AAA fire resisting shutter divided?: The fire shutter is divided into A / B / C classes. The refractory limits are not less than 1.2 /0.9 /0.6 hours. References to "general technical specification for steel fire resistance rolling shutter door GB 14102-93". 4.3 4.3.1 Classification according to fire resistance time. The common steel fire resisting shutter(see Table 3) The categories of the codes of the refractory time hF1 1.5F2 2.04.3.2 composite steel fire shutter composite steel fire shutter(see Table 4). Table 4 and Category Code refractory time hF3 2.5F4 3.04.4 refractory press time, smoke performance classification 4.4.1 ordinary steel fire anti-cigarette curtain (see Table 5) Table 5 and category code leak smoke refractory time h (20Pa pressure) FY1 1.5 ≤0.2m3 / m minFY2 2.0 ≤0.2m3 / m min4.4.2 composite steel fire anti-cigarette curtain (see table 6) table 6 and category code leak smoke refractory time h (20Pa pressure) FY3 2.5 ≤0.2m3 / m minFY4 3.0 ≤0.2m3 / m min excerpt complete fire shutter when the fire district for fire resistance of 3 hours, the opening portion on the firewall setting fire shutter fire resistance of 1.2 hours. **** Fire resistance of 3.0 hours called premium (fire back surface). "Construction Regulation" is mentioned in setting up a firewall and used as the separation of the fire resisting shutter and the fire?compartments. When taking the fire back surface temperature rise as the fire resistance standard of the fire resisting shutter, the fire endurance should not be less than 3.00h; When taking the fire back surface temperature rise as the fire resistance standard of the fire resisting shutter, the two sides of the roll should have protection of ?closed automatic water spray system, and the duration of water spray system should not less than 3.00h. In summary: The fire resisting shutter can be divided into: Grade, A, B and C looking to adopt
