有机防火堵料的使用寿命及特点
发表时间:2018-09-27 16:34:00来源:/

(1)良好使用环境。在室内常年恒温恒湿的场所,如铁路信号机房、电信公司机房、火力发电厂集中控制室等。在这类场所中有机防火堵料保持恒温恒湿且无日光照射,处于良好的保护状态。

(1) good use environment. Perennial indoor constant temperature and humidity places, such as railway signal room, telecommunications company room, thermal power plant centralized control room. In this kind of place, the organic fire-proof material keeps constant temperature and humidity without sunlight, and is in good protection condition.

(2)一般使用环境。在建筑物、构筑物内随季节变化进行冷热循环,空气湿度也随季节变化而变化,但无日光照射,温度也不会过高或者过低,基本随大自然的变化而变化的场所。如建筑物、构筑物内的楼道竖井、室内的电缆夹层、电缆的引入口、室内的建筑缝隙以及管道贯穿口等。这类场所的有机防火堵料经历自然的温度和湿度变化,无日光照射,处于一般的自然环境状态。

(2) the general use of the environment. In buildings, structures with seasonal changes in the cold and heat cycle, air humidity also changes with seasonal changes, but no sunlight, temperature will not be too high or too low, basically with the changes of nature. Such as buildings, structures in the corridor shaft, indoor cable sandwich, cable entrance, indoor building gaps and pipeline penetration, etc. Organic fire retardant plugging materials in such places undergo natural temperature and humidity changes, without sunlight, in a general natural environment.
(3)恶劣使用环境。在特殊的使用场所,高温、高湿、太阳直晒等场所。如室外的电缆隧道、发电厂、钢铁厂的电缆隧道,室外的变配电所等场所,这类场所的有机防火堵料长期处于比自然环境恶劣的状态。
(3) harsh environment. In special places of use, such places as high temperature, high humidity and direct sunlight. For example, outdoor cable tunnels, power plants, steel works cable tunnels, outdoor power transformer substations and other places, such places of organic fire retardant plugging in the long-term worse than the natural environment.

有机防火堵料的使用寿命。在良好使用环境下有机防火堵料的使用寿命比较长,堵料的理化性能基本保持合格,耐火性能逐年降级。这类堵料还可继续使用,在电缆更换、设备大修等情况下有机防火堵料可重复使用。在一般使用环境下,有机防火堵料的使用寿命一般,在一定时间内堵料可重复使用,在一定时间后后能保持一定的耐火性能,不拆除的情况下可保持相应的耐火性能使用。在恶劣使用环境下,有机防火堵料的使用寿比较短,一定时间后耐火性能也失去,因此在恶劣的使用环境中,应及时更换有机防火堵料,以保持相应的耐火等级。
The service life of organic fire plugging material. The service life of organic fire retardant plugging material is longer in good use environment, the physical and chemical properties of the plugging material are basically qualified, and the fire resistance is degraded year by year. This kind of plugging material can also be continued to use, in the case of cable replacement, equipment overhaul and other organic fire retardant plugging material can be reused. In general use environment, the service life of organic fire retardant plugging material is general, the plugging material can be reused in a certain period of time, after a certain period of time can maintain a certain fire resistance, without removing the case can maintain the corresponding fire resistance. In the harsh environment, the service life of the organic fire retardant plugging material is shorter, and the fire resistance is also lost after a certain time. Therefore, in the harsh environment, the organic fire retardant plugging material should be replaced in time to maintain the corresponding fire resistance grade.
