- Q: What is the importance of silicon powder in refractory processing?
- it depends on the type of refractory material, in addition to lS friends talked about, in the amorphous mobility\ strength should also have an impact
- 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: What are the applications of refractory in petroleum?
- It can be used in chemical filler. For general process, some insulation parts also need to use refractory.
- Q: What's the fire endurance of fire windows?
- That is fire resistance rating, fire-resistant time in the case of fire! It can be basically classified into the following levels and the fire endurance of the fire window is as follows as well: A class fire window: no less than 1.2h; B class fire window: no less than 0.9h; C class fire window: no less than 0.6h. This is in accordance with the latest specification of gb16809-2008 fire windows.
- Q: What are the basic requirements of continuous casting for molten steel? What are the requirements for refractory materials?
- The rapid development of the technology of continuous casting refractories so the corresponding development and improvement in variety and quality, continuous development of refractories for the continuous casting billet continuous casting production and quality have a significant impact. Especially, the completion and operation of Baosteel have greatly promoted the technological progress of refractory materials in China, and the refractory materials for continuous casting have made great progress both in variety and in quality.
- Q: How many grades of fire?rating are there for interior decoration materials?
- It can be divided into construction classification and fire resistance rating. Fire prevention for buildings. Fire prevention measures should be taken in the architectural design to prevent fires and reduce fire hazards to life and property. Building fire protection includes two aspects: fire prevention before fire disaster and measures in fire disaster, among which the former is mainly to confirm the fire resistant rating and fire-resistant structure.
- Q: what's the detailed address of fireproof and thermal inuslation matertial market?
- Following are the detailed addresses of fireproof and thermal inuslation matertial markets: Kunpengyu thermal insulation material co., LTD., Bantian street Daoban xuegang road 1-4, Jindu business building 503, Shenzhen Huameida rubber and plastic thermal insulation material wholesale, Shenzhen Longgang district Nanlian road 7, Nanpeng thermal insulation material Xiangxin road 1-4.
- Q: Why the corundum can be used as refractory
- Corundum has high refractoriness, so its high temperature performance is very good.
- Q: What kinds of refractory materials that can resist 3,000 Celsius degree?
- I think that graphite is the only one.
- Q: Can the teflon material resist fire?
- Teflon material does not burn, but the heat resistance temperature of it is about 300℃.
