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:How to deiron refractory?
Our company uses magnetic separation method.
Q:What is streaming fireproof material?
Since streaming fireproof material has less surface energy, so when it is placed in a location to be used, it can be automatically filled so long as mixed with water at proper ratio. And then using vibrator or vibrostand and other tools to compact the mixture so as to satisfy the use requirements. Therefore, it does not require vibration, and it has less friction force between the particles. Generally hydraulic refractory castable must be mixed with water at proper ratio when in construction . While, the concept of "streaming" is in terms of refractory castable.
Q:For refractory knowledge. What is the ratio of clay ramming mass?
Soil aggregates, dispersing agent, water reducing agent, plasticizer, binding agent and powder! ~ Bone meal feed approximately 6, OK
Q:How is the division of the fire resistant level of the rock wool board?
It's like this: China's national standard GB8624-97 divides the combustion performance of building materials into the following grades. Level A: non-flammable building materials. Level B1: flame-retardant building materials. Level B2: combustible building materials. Level B3 flammable building materials. section II Combustion performance and fire endurance of building components. First, The combustion performance of buildings of building components. The building is composed of components, such as foundation, walls, lubrication columns, beams, plates, roofs and stairs, ect. Building components are constituted by the building materials, whose combustion performance depends on the combustion properties of the used construction materials. Section One Combustion performance of building components. The building components are divided into three categories according to their combustion properties. First, non-combustible component: the component made by incombustible materials. The incombustible material refers to that when meeting the Oxygen in the air, it will not burn.
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.
Q:What is refractory cement?
How to use exactly refractory cement? Someone professional advised me to buy this cement. Does it differ a lot from common cement? Is refractory cement expensive?
Q:who knows the fire resistant level of fireproof gypsum board ?
Gypsum board is flame retardant materials, combustion performance rating B1, but when mounted on a steel joist, it can be seen as rating A(non-combustible material) . So it is fine to use as a ceiling. As for the Dragon brand, rock wool can be filled in the mddle according to its design requirements, using different series of gypsum board, steel stud. the walls may have fire resistance and sound insulation property of various degrees. You can randomly choose several samples to run some tests at the quality inspection insititute and the quality of these samples are subject to the testing results.
Q:What are the characteristics of the carbon composite refractories?
The features of carbon composite refractories: 1. It is with an aggressive high thermal shock resistance 2. Good resistance to molten steel and slag
Q:how to classify Insulating Refractory ?
Insulating Refractory by the physical form of the material is divided into: thermal insulation refractory slab, thermal insulation refractory blanket, thermal insulation refractory loose wool, and thermal insulation refractory irregular part. thermal insulation refractory material can also be classified by materials, temperature, manufacturing technique and application area.
