Assembly Process of Disposable Lighters and Hazards of Disposable Lighters
One-time lighter assembly process
Step 1: install the washer and put the washer into the lighter.
Step 2: put the sparker, and the regulator is installed on the screw valve to regulate the output air size;
Step 3: this step is particularly noteworthy, a critical step for success or failure.Commonly known as the "lever", the position and direction, pros and cons should be accurate and correct judgment, and the connection gap with the spark device should be relatively small to be correct;
Step 4: cover the plastic back cover and metal front cover. If the metal front cover is not good enough, you can properly pull it out to make it bigger in the middle.
Step 5: verify if you can, and if you fail, follow the process again and again to find the problem.Solve and succeed.
Hazard of a disposable lighter
Why is a one-time fire opportunity prone to violent explosions?This is due to the nature of the liquid butane, which is a colorless, flammable, and harmful gas, which turns into a liquid when liquefied under pressure.Flash point to - 60 ℃, spontaneous combustion point is 405 ℃, explosion limit of 1.9% - 8.5% and the minimum ignition energy for 0.25 mm.Saturated vapor pressure continuously increased with temperature rising and savings, is 160.1 kpa when 0 ℃, 30 ℃ is 413.4 kpa, 40 ℃ when 543.1 kpa, 50 ℃ to 702.2 kpa.General storage considerations: usually stored in a cool and ventilated warehouse.Warehouse temperature should not be more than 30 ℃, must be far away from fire and heat source, prevent the strong sun.
The liquid isobutane in a lighter will increase continuously with the change of ambient temperature, and the internal pressure will continue to increase. Sometimes large direct sunlight or friction, extrusion, collision, which is extremely prone to violent explosion.Therefore, people should pay great attention to the following important issues such as fire prevention and explosion protection when carrying disposable lighters for general storage, use or travel:
Do not put a one-time lighter directly in glass cabinet, cab, lest the direct sunlight makes the environment sharp temperature rise and cause a one-time lighter suddenly violent explosion burning.Also do not put one-time lighter in the place that is close to fire source, heat source easily, lest one-time drive machine is affected by heat violent explosion fire.
Take public transportation when you travel, and limit your lighters to a minimum.The country strictly official regulations each passenger can only carry a one-time lighter not more than 5.In order to ensure the personal safety of you and others, you can not take a disposable lighter when flying.Otherwise the one-time lighter suddenly produces violent explosion, that consequence is unimaginable.
After the family one-time lighter is used, want to put in the safe place that the child cannot get, prevent the child is taken disorderly take ignition carelessly, or carelessly gravity falls down lighter, because lighter is subjected to the action of external force also can produce violent explosion easily.
There is already a very large disposable lighter on the market. Most of these lighters are not anti-dropping. Even if some anti-dropping structure is used internally, they will not reach the standard range.Below the condition of high temperature or impinge, the force of explosion of oversize lighter is compared the power of small lighter blast to be sure to be mostly, the person that the environment of the home or job is bad or the heart is bad must not use easily.
