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 are first rate fire resistant window materials?: class A window not less than 1.2 hours, class B window not less than 0.9 hours, Class C window not less than 0.6 hours. technical requirments: 1, materials and accessories (1) the window frame is made with a certain strength sufficient to safeguard the integrity and stability of the steel frame or wooden frame. (2) steel frame and mound layer can choose the galvanized steel plate or stainless steel plate. Its selection standards is in line with GB12955 "Steel Fireproof Door General Technical Condition" provisions of Article 5.1. (3) wood frame and mound layer material selected from the standard should be consistent with GB14101 "General Technical Conditions of Wooden Fireproof Door" in the provisions of Article 5.1.1. (4 ) steel, wood frame the inside filler material should be incombustible material. (5) fireproofing glass can be used without affecting the fire windows fire resistance test approved product. light transmittance of glass should not less than 75% of commom sheet glass which is the same number of layers. ( 6) a sealing material between the frame and the fire-resistant glass flame retardant materials should be used, which can play the role of fireproofing and smoke insulation in case of fire (7) hardware fitting should be tested as approved supporting product

Q:Which brand of AAA refractory is good?: Foshan Nanhai Yanbu Shuying fire-resistant insulation material is very good, and it is a professional company of the production and sale of refractories. Our company specializes in the production of refractory bricks, refractory bricks, refractory castable, refractory aggregate, refractory materials, bauxite, alumina bricks and to undertake the production of various common refractory bricks and non-sizing bricks. The Zhengzhou Fire High Temperature Materials Co., Ltd. is also a good company. It is a collection of R & D and production company. The company mainly produces refractories, refractory bricks, refractory castable, refractory aggregate, refractory materials, special refractory bricks.

Q:whether the aluminum silicate thermal insulation material is fireproof or not?: aluminum silicate is fireproof, and the melting point is between -40 ~ 800 ℃. Aluminum: it takes the flint clay clinker as raw material, produced by resistance or electric arc furnace fusion and injection fiber-forming process. its characteristics: Low thermal conductivity, excellent thermal and chemical stability, without binder and corrosive material.

Q:How to understand qualitative and qualitative refractory materials?: Such as amorphous refractory castable, referred to as bulk loading, cast material, ramming material, refractory clay etc., utensils and other special products. Amorphous refractory material products, refractory heat insulating bricks and experimental and industrial crucible, spraying materials, such as burning bricks, electric melting brick, turn it into required shape and process heat treatment in where it is used.

Q:What are the structural properties of refractory materials provided by the manufacturer of the refractories include?: On the other hand, the turbulence is severe, and the side wall of the tundish is washed into the liquid steel and the service life of the lining of the tundish is reduced. In order to solve this problem, China 5%% honing develops a tundish anti turbulence pad, which is made of Al2O3>75% high alumina castable. Anti turbulence pad mounted casting ladle and tundish flow impact zone in the bottom of the flow out of the steel ladle nozzle casting hole center back in the anti turbulence pad repeatedly to consume the kinetic energy of the fluid flow, thereby reducing the steel flow speed, avoiding turbulence.

Q:What are the requirements of the performances of brasque refractory?: Physical properties of refractory include structural properties, thermal properties, mechanical properties, usability and operation property. The selection of the brasque refractory must have the following characteristics: 1. properties of not distortion and not melting at sufficient temperatures 2. have the necessary structural strength at high temperatures and does not soften and deform 3. must keep stable volume at high temperatures and will notcrack caused by expansion and contraction 4. will not rapture and flake when temperature is drasticly changed or heated unevenly 5. resistant to chemical erosion of metallic solution, slag and furnace gas, etc.

Q:What are the features of construction class A fire resistant door ?: 1, fireproof and thermal insulation Foam cement board is a Class A non-combustible inorganic heat preservation material which has good fireproof?performance can remain integrity after 3 hours baking at 1200℃. It can be used in buildings to improve fireproof?performance.

Q:How to distinguish the fire resistant level of the rubber and plastic thermal insulation material?: It is divided into level A, B1, B2 and B3. According to the current "burning behavior of building materials classification method", Level A insulation material is a non-combustible material, which belongs to YT. However, from the point of view of the current market , level A insulation material are very few, only glass wool, rock wool board, foam glass and vitrified micro bead. However, compared with level A insulation material, the more welcomed by the market is the organic insulation material. This is characterized as thermal insulation material, which is divided into three levels: level B1 is flame retardant, level B2 is flammable and level B3 is flammable. The level B1 nonflammable thermal insulation material is determined according to the fire endurance of the material. And different parts of the material are divided differently! Such as the common EPS / XPS insulation boards through special treatment of adding flame retardant. . Level B2 combustible insulation material is commonly the EPS expanded polystyrene foam insulation board and XPS board, that is, the ordinary plate. This material has low ignition point, and releases large amounts of harmful gases in the combustion process . Level B3 flammable insulation material is commonly the thermal insulation material taking polystyrene foam as the main material. Since this material is highly flammable, it has been out of the external wall thermal insulation materials. As for the civil construction insulation materials, China's current popular building insulation materials in the market are mainly made of three organic foams: EPS (molded polystyrene board), XPS (extruded polystyrene board) and PU (polyurethane).

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.
