Lithium battery as heater - be careful when using it to prevent fire

Lithium battery heaters such as electric stoves, electric irons, electric water heaters, and electric ovens have brought a lot of convenience to our work and life, but because the crawler heater has a relatively large power, improper use can easily cause a fire. Silicone rubber waterproof heating pads are thin sheets that heat up when powered on. The core is made of nickel-chromium wire or nickel-chromium foil etched into a certain shape, so it has high reliability. It is generally printed on insulating materials with any slurry such as graphite slurry and resistor slurry. Silicone rubber heating plate heating element: The nickel alloy heating wire is wrapped around the glass fiber, and the heating power can reach 2.1W/c㎡, and the heating is more uniform. Moisture-proof and chemical-proof silicone rubber materials provide longer heater life. Pressure-sensitive adhesive can be used for bonding on flat and smooth workpieces. Silicone rubber heaters are mainly composed of nickel-chromium alloy heating wires and silicone rubber high-temperature insulation layers. The silicone rubber high-temperature insulation layer is a thin sheet made of silicone rubber and glass fiber cloth (standard thickness is 1.5mm), and the silicone rubber heater has good softness.

First, due to long-term high-temperature baking, it is easy to ignite on combustible or nearby flammable materials:

Fourth, the resistance wire will continue to be used after multiple repairs, which may cause line overload and cause fire.

The fire protection system reminds that when using lithium battery heaters, flammable and explosive items cannot be placed near the tracked heater, and a certain safe working distance must be maintained; the lithium battery heater must be placed on a non-heat-conducting non-combustible material base; the safe interception flow management of the lithium battery heater wire must meet the capacity design requirements of my country's lithium battery heater; industrial lithium battery heaters must have separate circuits for protection devices in any case; there must be plugs installed between the wires, and the wire ends cannot be directly inserted into the socket; aging and damaged lithium battery heater wires should be discovered and replaced in time, and lithium battery heaters without self-installed fuses in the circuit shall not be used at the same time; when using the lithium battery heater, the teacher must be constantly supervised and the plug should be unplugged when leaving. During the use process, if there is a power outage, the plug should be unplugged in time and do not forget it; for the resistance wire that has been repaired by students many times, it is better not to use it anymore, and a new resistance wire should be replaced; it is strictly forbidden to use the lithium battery heater to dry flammable and explosive items; the electric oven should have a device to control different temperatures, which should effectively prevent the temperature from being too high and the baking time from being too long.
