Shuangkai Lighter - Pursue quality and cast high-quality goods.
Disposable plastic lighters are people's daily necessities, especially for people who smoke a lot, they are a must-have item on the body, and they always take their lighters wherever they go. However, many people think that lighters are originally so small that there is no major danger. This is a big mistake because some accidents that cause serious explosions due to improper storage of lighters are not uncommon nowadays.
Why are disposable plastic lighters prone to explosions? This is due to the nature of liquid butane-filled-in disposable plastic lighters. Butane is a colorless and flammable harmful gas, and it turns into liquid immediately after being liquefied under pressure. The flash point is -60°C, the auto-ignition point is 405°C, the explosion limit is 1.9%-8.5%, and the minimum ignition energy is 0.25 mJ. The saturated vapor pressure keeps increasing with the increase of temperature. It is 160.1kPa at 0°C, 413.4kPa at 30°C, 543.1kPa at 40°C, and 702.2kPa at 50°C. General storage precautions: Usually stored in a cool and ventilated warehouse. The temperature of the warehouse should not exceed 30 ℃, and it must be kept away from fire sources, heat sources, and strong direct sunlight.
The liquid isobutane in the lighter, with the continuous increase of the ambient temperature, the internal pressure will continue to increase, and sometimes combined with direct sunlight or friction, extrusion, or collision, it is extremely prone to an explosion. Therefore, when people usually store, use or carry disposable plastic lighters as much as possible, they should pay great attention to the following important issues such as fire and explosion protection:
Do not put disposable plastic lighters directly in glass cabinets or cabs, to avoid the sudden and violent explosion and combustion of disposable plastic lighters caused by the sudden increase in the temperature of the environment caused by the direct sunlight. Also, don't put disposable plastic lighters in places close to the fire and heat sources, to avoid the one-time punching machine being heated and violently exploding and catching fire.
When taking public transportation when traveling and playing, disposable plastic lighters should be carried in as limited quantities as possible. The state strictly stipulates that each passenger can only carry more than 5 disposable plastic lighters. To ensure the personal safety of you and others, disposable plastic lighters should not be carried on the plane. Otherwise, the disposable plastic lighters explode violently, and the consequences are unimaginable.
Disposable plastic lighters in the family should be placed in a safe place out of the reach of children after use, to prevent children from ignoring the lighters, or accidentally dropping the lighters with gravity, because the lighters are prone to explosions under the action of external forces.
