- Q: Who know what kind of fire shutter fire rating are there?
- The fire resistance limit of high steel structure reduces the loss of fire, achieves remarkable results. The specification is mae in order to unify the application technical requirements of the design, construction method and quality standard of the steel structure fire retardant coating, and ensure the application effect, safety. The specifications is formulated in accordance with national engineering construction of the relevant policies and "giving priority to prevention, combining fire prevention and fire extinguishing. investigated characteristics of steel structure fire in China, summed up the experience of fire resistant coating for steel structure, and absorb domestic and foreign advanced technology and scientific achievement in fire retardant coatings for steel structures, and repeatedly solicited the relevant scientific research and design, production of construction, colleges and universities, public security department
- Q: What is the importance of silicon powder in refractory processing?
- it can certainly improve the fire resistance
- Q: Does anyone know the difference between refractory and thermal insulation material?
- Refractory refers to inorganic nonmetallic material, whose refractorinessis not less than 1,580℃, but refractory is not necessarily insulated material. Inorganic thermal insulation material also belongs to refractory as long as its refractoriness is higher than 1580℃.
- Q: Which industry does refractory belong to? Does it belong to construction industry?
- It belongs to material, and after all, more than 60% refractories are used in metallurgical industry. If you insist on classifying it, it belongs to supporting industry of metallurgical industry. Refractory industry itself is independent.
- Q: Who knows what kind of fire prevention materials are there?
- 1, Fire-proof board Fire-proof board is the most frequently used materials in the market. There are two kinds of fireproof boards which are commonly used; one is the high pressure decorative board, which has the advantages of fire prevention, damp proof, abrasion resistance, oil resistance, easy cleaning, and more variety of colors and designs. The other one is a glass magnesium fire board, the outer layer of which is a decorative material, the inner layer of which is a mineral glass magnesium fire material. It can resist 1500-degrees high temperature, but not suit for decoration. The installation of fireproof ceiling in the exit passageway, stair well and corridor can ensure safety evacuation, and protect people from the spread of the fire. 2 Fire-proof door Fireproof door is divided into wooden fire proof door, steel fire proof door and stainless steel fire proof door. Usually the fire proof door is used for the opening of the firewall, the entrance to the staircase, the evacuation of the aisle, the openings of the pipeline and other parts of the building, and it has an important role in fire separation and reducing the loss from fire. 2 Fire resisting shutter I hope it may be helpful to you.
- Q: What are the insulation fireproofing materials?
- Insulated shoes, insulated gloves, tape (cloth, plastic, as well as waterproof) yellow wax tube, mouth care, fireproof (ie asbestos cloth is sold by jin) there is pressure-caps black tape, waterproof tape ,casing. There are glass fiber needle felt is widely used in electrical, chemical, construction, transportation, automotive and other industries interlayer insulation and silencer system, and used as an insulating fireproof material.
- Q: what's the fire endurance of fireproof?panel?
- fire endurance of fireproof?panel can reach 3 hours. For example, 12 mm non-asbestos fiber reinforced calcium silicate board, fireproof?panel, two single 75 keel. through the monitoring of national fireproof construction materials quality supervision center, it's security and refractory time will reach over 3 hours. fireproof?panel, also called fire resistance board, scientific name is thermosetting resin impregnated paper laminated wood,english abbreviation HPL(Decorative High - pressure Laminate) is fire resistant building material for surface decoration and has rich surface colors,lines and special logistics performance, it's widely used in interior decoration, furniture, cabinets, laboratory table, external wall, etc.
- 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: Does anyone know about the classification standards of B2-level fireproof and thermal insulation materials?
- The fire-resistant differences of B1- and B2-level extruded insulation boards are as follow: B1-level materials will be smothered as soon as staying away from fire, namely, they will be extinguished after leaving fire, or be put out in 10 seconds. B2-level materials will be in low-grade combustion, namely, the fire will not get wilder, and drippings will not ignite the filter paper. I hope my answer can help you!
