摘要:
为研究碳纤维混凝土在低温下导电发热性能,测试低温下碳纤维混凝土的融雪化冰能力以及相互之间的关系,为冬季公路或机场的融雪化冰工程奠定基础。采用模拟的方法进行实验研究,分别研究了低温下碳纤维混凝土的发热规律、3 mm冰层覆盖情况下的融雪能力、外界温度与除冰时间关系、电热功率与除冰时间关系。结果表明:在-25 ℃情况下,2%碳纤维含量的碳纤维混凝土在36 V交流电压的作用下80 min左右温度达到0 ℃,且随着时间的推移,温度上升速率不断增加; 在3 mm冰层覆盖下,通电80 min时冰层开始融化,120 min时冰层基本融化完,说明在“中雪”情况下,通电120 min就能保证“旧雪”完全融化完毕; 随着电热功率的增加,碳纤维导电混凝土的融雪能力也不断增强,根据实验数据可以得出碳纤维导电混凝土的最经济导电功率为500~700 W/m2.低温时,不同温度情况下,随着温度的变化,融雪化冰时间也随之变化,随着温度的“上升”,融雪化冰时间几乎成直线下降,外界温度越接近0 ℃,融雪化冰时间越短。在-5 ℃情况下,碳纤维混凝土温度上升到0 ℃只需要46 min.
Abstract:
The conductive and heating properties of carbon fiber reinforced concrete at low temperatures were studied.The capability of melting and deicing ice of carbon fiber reinforced concrete at low temperatures and their relations were studied.These studies may lay the foundation for melting and deicing ice at the winter road or the airport.The experimental work was studied for carbon fiber reinforced concrete using the simulation method.The heating rules of carbon fiber reinforced concrete at low temperatures,the snow melting ability under the condition of 3 mm ice cover,the relationship between the outside temperature and deicing time,and the relationship between heating power and deicing time were studied.It is pointed that the temperature for 2% of the carbon fiber content of carbon fiber reinforced concrete may reach 0 ℃ from -25 ℃ for 36 V AC voltage under the action of 80 minutes.It is found that the rising rate of temperature increases as time goes on.The ice 3 mm under the ice surface began to melt under 80 minutes of electricity time and it is vanished after 120 minutes.The results indicate that for the median snow,the covered snow may completely be melted after 120 minutes of electricity time.It is also pointed that the capability of melting ice increases with increasing the electric power.The results indicate that the most economical conductive power of the carbon fiber conductive concrete is 500~700 W/m2.At low temperature,the time of snow melting is changing with the change of temperature.With the increase of temperature,the time of snow melting almost drops linearly.The closer the outside temperature is to 0 ℃,the shorter time melting snow need.It takes only 46 minutes to increase the temperature of CFRC from -5 ℃ to 0 ℃.
