Q:Does the refractory material used in steelmaking all refer to refractory brick?
For example, refractory castable doesn't only refer to refractory brick, but also some bulk material and ramming mass. Desulfurizer belongs to ferrous metallurgy auxiliary material.
Q:Who knows what material is in the center of fireproof rolling curtain?
Material and the type high silica cloth as curtain, side rails, with galvanized steel in its end and stainless steel two kinds of materials with double curtain in the end I hope my answer can help to you
Q:What's the fire endurance of A grade fireproof glass curtain wall?
An hour and a half, an hour, and half an hour. As a key step in the home fire prevention, fire door is particularly important. According to the fire endurance and heat insulation performance, it can be classified as follows: A class fire door with fire endurance of no less than 1.5h; B class fire door with fire endurance of no less than 1h; C class fire door with fire endurance of no less than 0.5h. We can choose according to different needs, while A class fire door and B class fire door are now commonly used. Fire door has great varieties, and the material it uses is also of wide range. It includes stainless steel fire doors, glass fire doors, steel fire doors, etc. The most important feature of fire door is its fire resistance period. The main difference between A class fire door and B class fire door lies in their fire endurance, of which the former is no less than 1.5h, while the latter is no less than 1h. Difference between A class fire door and B class fire door also lies in their fireproofing material. That is the thickness of the built-in fire prevention board, of which A class fire door is 52mm, while B class fire door is 46mm. Therefore A class fire door obtains longer fire resistance period than that of B class fire door and gains better fireproof performance. A class fire door and B class fire door also differ in the places they are used. A class fire door is generally used in important fire fighting access of machine rooms, warehouses and oil depots, etc. and flammable and explosive public places, while B class fire door is generally used in the ordinary fire fighting access of some ordinary buildings. But B class fire door is more widely used than A class fire door.
Q:What's the fire retardant material of roller shutter fire resistance door ?
It is composited by inorganic materials, and main componets are perlite and inorganic adhesive, etc.
Q:What are the materials of insulation firebricks?
The raw materials of firebricks, firebricks have various raw materials, and the composition of which can be divided into six categories: soil, stone, sand, mineral, powder and others. One of the raw materials, soil: bauxite, kaoline, clay, diatomite Another raw material, stone: fluorite, kyanite, andalusite, forsterite, vermiculite, mullite, pyrophyllite, chlorite, dolomite, sillimanite, magnesia-alumina spinel, and silica Another raw material, sand: clay sand, zircon sand, quartz sand, and magnesite Another raw materials, mineral: chromium mineral Another raw material, powder: aluminum powder, micro-silica powder, and silicon powder Another raw materials, others: asphalt, graphite, phenolic resin, perlite, cenosphere, sialon, corundum, silicon sulfate, silicon carbide, sodium silicate, silica sol, boron carbide, calcium aluminate cement, nitride material, haydite, aluminum oxide, alumina sol and zirconia, etc.
Q:Does the production of refractory belong to advanced technology?
It certainly is advanced technology as it is the new material.
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:What are the additives and recipes of refractory?
You can try FDN.
Q:what should be paid sttention when buying the refractory?
First, look at the appearance of the product, it will be better if the surface of product is smooth, if there are the injuries and damages which may influence the use, do not use it. Second, the main characteristics of insulation material is flame resistance, reduce the loss of fire occurred at the time of purchase combustion performance testing products, non-combustible stone wool products are the best. Third, refractory insulation with good hygroscopicity is also very important, it can keep your room drying for a long time , played the role of moisture-proof, and more capillary, the hygroscopicity is better.
Q:what materials can make external wall fireproofing paint have the fireproofing effect
Adding flame retardant or fire retardant materials can be fireproofing, which commonly referred to as the external walls of fire retardant coating or fire retardant coating. Principle: Fireproof paint itself is flame-retardant or non-combustible, so that the protected base material can not directly contact with the air in order to the ignition delay and reducing the burning speed; except that, it also has a lower thermal conductivity, which can delay the transfer of flame temperature to the protected base material; fireproof paint thermal can decompose non-combustible inert gas by heating to dilute the thermal decomposition of combustible gas in protected object, making it difficult to burn or slow down the speed of burning.
