Q:How many hours of the fire endurance time of the rock wool laminboard?
Hello. The fire endurance now on the market is generally about two hours. The 50mm color steel sandwich version of Bo magnesium rock wool, with refractory time being five or six hours, is very good.
Q:What's the definition of fire endurance of the fire-resistant coating for steel structure?
1. Fire endurance. Conduct fire resistance test of any building component according to the standard time-temperature curve, and the time when it is subjected to the fire to the time when it loses support capability or fire insulation function or its integrality is destroyed is referred to fire endurance. 2. Steel has relatively low fire endurance which is usually 0.25h only, namely 15 minutes; 3. Of steel structure buildings, steel can be used as beams, pillars, etc. but its fire endurance is not enough (usually these components have higher requirement on fire endurance, and take pillar as an example, it is usually demanded that the fire endurance should be 2-3h), and under this condition, it needs to brush fire retardant coating so as to raise the fire endurance. As to the specific quantity or types of the fire retardant coating, it is decided upon the actual conditions. In short, the building material needs to meet the required fire endurance of the buildings.
Q:What kind of refractory material should be used for common boiler?
Build by using clay refractory mortar. Common clay brick is used as combustion layer. Xindeyuan Refractory Material, red brick is used as external wall. Light clay brick is used as thermal insulation layer, thank you.
Q:what should be paid sttention when buying the refractory?
solve the resources and the cost as much as possible. Accurate understanding and knowing the material temperature changes of various partsin order to choose the appropriate refractories. 4: 3, work performance, for example, take measures to ensure the overall life, and it is a very good buying principles: melting in high temperature metal erosion. These are the four major problems to consider when using refractory. You can choose low prices and low transportation costs of materials to meet the basic principles under the conditions described above. 2.carefully observe the material to prevent the desturction and reducing the costs. according to the structure of furnace, reasonable coordination of all parts of the material, fully take the advantages of material characteristics and strive to develop the recycle, to avoid the destruction of the materials.1. the working characteristics and the sport condition and analyze the reason of destroying the material, which can not only gurantee the product quality and reduce the expenses, get familiar with the chemical component and physics of the material.
Q:How to apply the alumina powder on refractories?
The most common one in use is the refractory bricks.
Q:What are the requirements of the performances of brasque refractory?
It is a kind of inorganic non-metallic material whose refractoriness is not lower than 1580 ℃. Refractoriness is the centigrade temperature of refractory cone specimen wiyhout any load resisting high temperatures without melting down But only refractoriness can not fully describe the refractories, 1580 ℃ is not absolute. Refractory is now defined as material of physical and chemical properties allowing to be used in high temperature environments. Refractory is widely used in industries like metallurgy, chemical, petroleum, machinery manufacturing, silicates, power, etc., which is mostly used in the metallurgical industry, accounting for 50% to 60% of total output.
Q:which kind of material should be used in fireproofing cabinet?
Cabinet fireproof panel can be divided into fiber cement fireproofing board, metal fireproof panel, mineral wool fireproof panel, perlite fireproof panel and many other fireproof panels. Wherein fiber cement fireproofing board is a new material with growing popularity , it has good thermal insulation and sound insulation performance and belongs to a1 level fireproofing material. Fiber cement fireproofing board is a kind of decoration sheet that takes silicious material or calcareous material as the main raw materials and is made by being combined with fibrous material and other additives in certain proportion. Metal fireproof panel is a kind of sandwich dalle that takes aluminium plate, stainless steel plate, colorful steel plate and other metal materials as main raw materials and is made by adding some fire retardant materials. Mineral wool board is a kind of fireproofing decorative board that takes mineral wool and glass wool as the main raw materials. Perlite fireproof panel is a kind of fireproofing hollow plate that take low alkalinity cement as the main materials and fireproofing perlite as filler.
Q:what is the material of fixed first rate fire resistant window?
Fixed first rate fire resistant window is produced by the steel sash windows, steel casement, fireproofing glass. Fireproof windows, is composed by steel window frame, steel casement, fire-proofing glass. it refers to the window which can isolate and stop the fire spreading. The fire window product is named after the main material of window frame and the window casement, window frames is made of steel, casement is made of wood or the sash frame is made of wood and the casement is made of fire window.
Q:How to choose thermal insulation materials for flood heating?
How to choose the appropriate thermal insulation materials: 1, Thermal insulation material shall have a small thermal conductivity, good thermal insulation properties. Besides, that also depends on whether the specific temperature changes of in the insulation materials' working environment can ensure the material has good thermal insulation. 2, when purchasing, we must be make sure it is light, and loose enough. These heat insulating material can not only afford bracket, and can also increase the heat transfer performance of the heat insulation material. prevet water penetration. Waterproof function should be soild, even if it accidentally absorbs water, its thermal insulation function must be guaranteed. 3, None of the organic material should applied to production of insulation materials, Thermal insulation material containing organic matter may get rotten, mildewed, and cause other destructive . At the same time they should not contain flammable substances, in order to avoid the fire. I hope my answer can help you
