红外线加热是通过液化石油气 (LPG)的燃烧,激发金属材料或陶瓷介质产生红外线,利用红外线照射待加热路面,但由于红外线波长通常在1 mm左右, 所以加热深度通常只有3-4 cm,而且表层与里层温度梯度较大。由于该方式无法控制面层温度,所以会造成表层沥青科烧焦,从而达不到再生的目的。
Infrared heating is the combustion of liquefied petroleum gas (LPG), excitation of metal or ceramic medium to produce infrared, the use of infrared light to be heated pavement, but because the infrared wavelength is usually about 1 mm, so the heating depth is usually only 3-4 cm, and Surface and inner temperature gradient. As the way can not control the surface temperature, it will cause the surface asphalt Branch scorched, so as to achieve the purpose of regeneration.
