The lighter uses liquefied butane gas as fuel, and electronic ignition or steel wheel friction calcium carbide as the ignition source. The size of the flame can be adjusted. The transmission fire structure has friction type, pick-up type and hand type.
Butane (CH3CH2CH2CH3), also known as n-butane, is a general term for two alkane hydrocarbons having the same molecular formula (C4H10). These include: n-butane and isobutane (2-methylpropane). Butane is a flammable, colorless, easily liquefied gas. It is an important raw material for the development of petrochemicals and organic raw materials, and its use is receiving increasing attention.

Nature: colorless flammable gas. The melting point is 13535C, the boiling point is 05C, the relative density is 0.5730 (25C), the refractive index is 13326 (20 ° C), and the critical temperature is 1520l. C, critical pressure 38OkPa, critical volume 4387mlg. Insoluble in water, soluble in ethanol, ether, chloroform and other hydrocarbons. Forms an explosive mixture with air with an explosion limit of 19% to 84%.
