Q: what kind of refractories is used to make the industrial silicon furnace mouth long life?: Fused zirconia corundum brick, the smelter of the glassworks is used this kind of lining, and you can contact by private letter.

Q: What's the fireproof specification for constrcution external wall thermal insulation materials?: Specification for constrcution external wall thermal insulation materials: Article 1 In order to implement the "State Council opinions on strengthening and improving fire prevention work" (state issued [2011] No. 46), to standardize fireproof design and application of external wall thermal insulation materials of newly constructed, renovated, and expanded civil buildings and to prevent and reduce fire of building external wall thermal insulation materials, this provision is made in accordance with relevant national technical standards and our province real situation. Article 2 When there is no cavity between external wall thermal insulation material for exterior wall and base wall and between decorative layers, the insulation system shall comply with the following provisions: (A) Residential buildings: 1. When the building is higher than 54m, combustion performance of the thermal insulation material shall be A level; 2. When the building is not higher than 54m,combustion performance of the thermal insulation material shall be at least B level. When using B1 level insulation materials, non-combustible materials should be used to make the protective layer, and a protective layer thickness of the first floor of the building should be not less than 10mm, the other floors not less than 5mm; incombustible?materials of more than 300mm height should be used to make horizontal fire barrier zone in every floor. (B) Other buildings in addition to residential buildings

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: How long is the fire resistant limit for ultra thin fire retardant coating?: There is no detailed stipulation for ultra-thin fire retardant coating, and the thickness of the inside is the fire resistance limit shall reach certain time(at least). In engineering, the thickness of the fire retardant coating is generally determined according to the manufacturer's testing report. We use thin fire retardant coating for steel structure: if the fireproof limit is 2.5 hours. the thickness should be 4.9mm. If fire-resistant limit is 2 hours, the thickness shall be 3.5mm. If the refractory limit is 1.5 hours, the thickness shall be 1.75mm. If the limit is 1.0, the thickness is 1.17mm hope my answer can help you

Q: which kind of refractory is used in golden smelting furnace? How about his using temperature: generally the price of the quartz sand refractory material is higher and the temperature can meet the requirement of 2000 degree.

Q: How to distinguish between class A fire resistant door and class B fire resistant door from appearance ? What are the differences between the two refractories? Thank you !: First, the materials are the same. But the thickness of grade A and grade B fire doors is different juding from their appearances. Grade A :50. Grade B:45. Added question: Do you refer to steel fire door?

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

Q: What are the advantages and disadvantages of new external wall fireproof and thermal inuslation matertials?: Advantages: 1)Low requirements on the waterproof, weather resistance and other technical indicators. The dry wall and gypsum plastering mortar, etc. can meet the requirements and can be easily obtained; 2) The inner insulation material are separated by the floor, and construct within a height of only a storey , without erecting scaffold ; 3) In the hot summer and cold winter or hot summer and warm winter area, the inner insulation meets the requirements; 4) The glass beads overcome the shortcomings of expanded perlite, like, large amount water absorption, easy powdering, big volumetric shrinkage in the slurry mixing process, easily leading to post-insulation product performance degradation and hollowing, cracking, and also make up for the defects of polystyrene particles organic materials, like, flammable, poor fire performance, producing harmful gas at high temperatures and anti-aging, poor weather resistance, poor workability and large rebound in construction, ect. Disadvantages of external wall insulation : 1) Since the ring beam, slab and column structure would cause thermal bridges, leading a greater heat loss; 2) It is of low intensity, high water absorption, easy to shrink and crack. The insulation system is prone to cracking, leaking or loss and other common quality problems, especially it is easy to crack at the seams, thus being difficult to exsit as long as the building. 3) It is inconvenient for the users to redecorate and hang ornaments; 4) It takes up indoor used space;

Q: What material is used for making refractory stone bowl?: It is attractive and diverse in appearance, hard, and heat fast, not stick food when using. The cooked food is attractive and delicious and rich in various trace elements which is beneficial to the human body. It is also of high quality, and all these make it popular among the customers.
