Why can't gasoline be stored in plastic barrels? Will gasoline spontaneously combust when exposed to the sun?

As people's living standards improve, almost every household owns a car, which brings great convenience to people's travel. Therefore, gasoline has become an indispensable vehicle product in people's lives. Gasoline is a dangerous good, so it is very necessary to learn the relevant knowledge about gasoline. Let's open it and take a look!

Why can't gasoline be stored in plastic barrels?

Because gasoline is a Class A flammable liquid with a flash point of less than 28°C and an explosion lower limit of less than 10%, and plastic containers are not conductive, injecting gasoline directly into a plastic barrel can easily cause static electricity to accumulate, thereby generating static electricity sparks and causing an explosion. Therefore, gasoline must be contained in metal containers such as iron barrels and iron kettles.

Gasoline is a flammable and dangerous good. When filling flammable liquids such as gasoline, the problem of static electricity elimination must be considered. The energy of static electricity itself is very small and the human body generally cannot feel it, but many dangerous goods may burn or explode when encountering this static electricity spark.

When filling flammable liquids such as gasoline with iron barrels, certain grounding measures should be taken so that the static electricity generated by the friction between the iron barrel and the liquid can be immediately discharged through the ground wire. In addition, a small amount of magnesium stearate or acetic acid can be added to the gasoline to increase the conductivity of the gasoline.

Will gasoline spontaneously ignite when exposed to the sun?

Although gasoline will not spontaneously ignite when exposed to the sun, it is recommended to store it in a cool place. Experiments have shown that the auto-ignition point of gasoline is 427 degrees Celsius. When the air temperature reaches 427 degrees Celsius, gasoline will spontaneously ignite without an open flame or heat source.

Gasoline generally will not spontaneously ignite when exposed to the sun in the absence of other open flames or heat sources. If the gasoline is not sealed, it will gradually evaporate when exposed to the sun.

Generally, gasoline will not spontaneously combust when exposed to the sun in a sealed state. Currently, almost all sealed oil barrels contain anti-explosion agents, and being exposed to the sun will only affect the quality of the gasoline due to the increase in pressure inside the barrel.

How much is one liter of gasoline?

One liter of gasoline weighs about 1.4 to 1.8 jin. One liter is equal to 1000 milliliters, and the density of gasoline is 0.7-0.78 grams per square centimeter. According to the calculation formula of volume, density and weight, one liter of gasoline weighs about 700-780 grams, that is, 1.4-1.8 jin.

Different types of gasoline have different densities. For example, the density of No. 93 gasoline is 0.725 grams per cubic centimeter, and the density of No. 97 gasoline is 0.737 grams per cubic centimeter, so the weight per liter of No. 93 and No. 97 gasoline is also different.

In addition, weather temperature is also one of the factors that affect gasoline density. Generally speaking, the temperature is higher from April to September, and the average density of No. 90 gasoline is lower, about 0.734 kg per liter, while the temperature is lower from December to March of the following year, and the density of No. 90 gasoline is about 0.758 kg per liter.
