▎ 摘 要
NOVELTY - The sheet has a cylindrical graphene heating sheet main body whose outer side surface is covered with an inflaming retarding mica sheet layer. An outer side of the inflaming retarding mica sheet layer is formed with a Polyethylene terephthalate film layer. An outer surface of the Polyethylene terephthalate film layer is coated with patterns. An inner portion of the graphene heating sheet main body is formed with a cavity. A spiral channel is arranged at the cavity. Two sides of the heating sheet main body are provided with an arc sheet. A corner of a square-shaped section is provided with a circular arc guide plate for changing a right angle to a round angle. USE - Flame-retardant mica sheet integrated graphene heating sheet. ADVANTAGE - The sheet can increase number of the inflaming retarding mica sheet layers to reduce fire accident possibility so as to improve safety performance and heating efficiency and increase rapid radiating speed. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a flame-retardant mica sheet integrated graphene heating sheet.
