Chemicals are closely related to life----the use of gas characteristic

The first and most characteristic feature of liquefied petroleum gas is the explosive nature of liquefied petroleum gas. Generally, when a liquefied petroleum gas safety accident occurs, an explosion will occur and it will explode before burning. The main reason is because the calorific value of liquefied petroleum gas is relatively high. It is several times higher than the calorific value of ordinary gas to compare liquefied petroleum gas from the calorific value, so it will appear when there is a safety accident in liquefied petroleum gas. The situation of the explosion. Combustion occurs after the explosion, and the burning of liquefied petroleum gas is similar to the power of the explosion and is highly destructive.

1) Flammability of liquefied petroleum gas

Liquefied petroleum gas has the main components of petroleum. These components include propane, butane, propylene, butene, etc. The components are typical hydrocarbon compounds, and the largest characteristic of hydrocarbon compounds is flammability. Moreover, the flash point and the self-ignition point of these hydrocarbon compounds contained in the liquefied petroleum gas component are very low, and it is easy to cause combustion.

(2) Toxicity of liquefied petroleum gas

Liquefied petroleum gas is a toxic gas, but the volatilization of this toxicity is conditional. Only when the concentration of liquefied petroleum gas in the air exceeds 10% will the toxicity of the reaction occur. When the human body is exposed to such toxicity, it will cause vomiting, nausea or even coma, which will cause great harm to the human body.

(3) The flowability of liquefied petroleum gas

Liquefied petroleum gas is very easy to flow, and in the event of a leak, liquefied petroleum gas will flow out of the reservoir. In general, 1 liter of liquefied petroleum gas will volatilize into about 350 liters of gas after flowing out. These gases will burn when they encounter electricity, causing a serious fire.

Therefore, pay attention to the use of security.
