- Q:Who knows what kind of fire prevention materials are there?
- Plant use general steel structure more often without too much modification. If there is a need for modification, boards which can meet the requirements of fireproof are suitable, such as gypsum boards and aluminium sheets. As for coating, it is favorable to use coating that has fine powder, high density and better sealing. Hardening agent mainly depends on the specific requirements.
- Q:Who knows about the criteria of fireproof and thermal insulation materials?
- Seven levels are divided according to "The classification of combustion performance of building materials and products", namely, A1, A2, B, C, D, E, F. It mainly refers to the combustion performance of materials. You can check on this standard for the specific dividing evidence. There are detail charts which mainly describe that whether there is drip or not, the ignition time, continuous burning time and so on.
- Q:What are the additives and recipes of refractory?
- SM water reducing agent
- Q:Can anyone tell me what is A-leve fireproof material?
- What you say is probably palstic! B-level means the fireproof rating is at B1-level because palstic material doesn't belong to fireproof materials. It only is fire?retardant. When wholesaling all kinds of insulation materials and construction, it need tos look at the names. B1-level refers to the fire endurance rating of the fireproof material, which is determined according to the fire resistance of the material. In addition, different parts of the material have different fire endurance ratings! You can download a "Specifications of Fireproof Design for Buildings" for further information!
- Q:What are the new refractories? What are the features? How about their application and development?
- In metallurgy, in what position should it be used, in order to make the best. Answers are as following. In iron, steelmaking or converter. When questioning, pay attention to the ways. Answers: Try to use synthetic refractory materials.
- Q:What are the main components of refractory cement?
- Refractory cement, also known as aluminate cement, can also be gray. Aluminate cement is often yellow or brown. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. The main mineral of aluminate cement is mono calcium aluminate (CaO · Al2O3, abbreviated CA) and other aluminates, and a small amount of dicalcium silicate (2CaO · SiO2), etc.
- Q:Does anyone know what is the use of waste refractory materials?
- 1.Waste refractory bricks can be reused to make the refractory bricks after being crushed by crusher, but the price is not very high. The purchasing price of refractory plant is ?60/ton. Because the refractory material has been calcinated for two times, it becomes easier to make bricks expansion coefficient with waste refractory bricks, but too much is inadvisable. If too much, the refractory materials would have a bad combination, which will give rise to loose bricks and incomplete corners. Nowadays, ordinary refractory plants would purchase waste refractory bricks to produce bricks, but better plants wouldn’t do this.
- Q:Are refractory materials and fireproofing materials the same?
- Refractories are generally used in the industry such as power plants, electric stove and industrial furnace. They include refractory bricks and insulation materials. Fireproof materials are generally used in building and they are fireproofing.
- Q:Who knows the setting requirements of roofing fire barrier zone?
- First, the the minimum of fire barrier width is greater than 30cm, and the thickness should be same to the thickness of the insulation materials. Fire barrier zone insulation board must do the whole area sticking construction with the base wall during the construction. Fire barrier zone insulation board is required to assistant binding by anchor bolt, anchor bolt must suppress the underlying mesh. Second, Fire barrier zone should be set at the upper position of door and window openings, the distance between the low edge of isolation belt and the upper edge of the window must be less than 50cm. The thermal resistance of fire barrier zone must be half than EIFS thermal resistance in the cold northern areas, while the thermal resistance of fire barrier zone must be three times than EIFS thermal resistance in the hot summer and cold winter area. Third, When the fire barrier zone is set on the edge of the window, fire barrier zone at the upper part of the window should do flanging when sticking, flanging glass fiber mesh must exceed 10CM than firebreak insulation board. Flanging network, underlying network and surface network can not be overlapped or butted at the top of the window. I hope you can be satisfied
- Q:Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?
- If the outer packing is made of solid wood, it must be fumigated! If it is not solid wood, you can do without!
