An engineering electric blanket is a heating product made by the composite technology of glass fiber aluminum foil fabric, glass fiber felt, and silicone heating wire. It features certain thermal insulation, heating, waterproof, fireproof, and abrasion-resistant properties. It is widely used in winter concrete construction and maintenance to increase the temperature around the concrete, ensuring normal curing of the concrete.

The working principle of an engineering electric heating blanket involves weaving or sewing the electric heating wire in a serpentine pattern into the insulating material. Once powered, it emits heat and is controlled by a temperature control element. Its basic composition includes the heating layer, outer layer, insulating layer, as well as temperature control and safety components.

Engineering electric heating blankets are primarily used for heating and curing concrete during winter construction. After the concrete is poured, cover it over the concrete surface or outside the formwork, then power it on to heat and cure the concrete, accelerating the solidification process. This method offers significant advantages in cold temperatures, tight schedules, and high quality requirements, making it more valuable for wider application compared to traditional curing methods.
