Some people believe that manufacturers produce long and short gas cylinders to attract more people.
At present, the commonly used picnic fuel is butane gas canisters. Many people have a question when purchasing this type of gas. To be honest, few people really pay attention to the difference between them. They think flat gas cylinders are small and easy to carry, so they buy them. Some people believe that manufacturers produce long and short gas cylinders to attract more people. Some people think that flat gas cylinders are more stable and prefer to use flat gas cylinders, while others think that flat gas cylinders are expensive and must be bought for a penny. In fact, these are wrong.
In fact, these two gas cylinders are not only different, but also contain different gases. Long gas cylinders are commonly used, with a capacity of 220g. Their gas is liquefied butane, while the gas in flat gas cylinders is isobutane. The names of these two gases sound similar, but their gasification points are different. The gasification point of butane is 0 degrees, while the gasification point of isobutane is -12 degrees. what do you mean? In other words, when butane gas is used at or below 0 degrees, it can be said that it cannot be used because butane is in a liquid state at or below 0 degrees and cannot become a gas, cannot be flushed out of a gas cylinder, or ignited on a furnace. Similarly, isobutane is only in a liquid state when the temperature is below -12 degrees Celsius, and therefore cannot be used.
Do you understand? Flat gas cylinders are designed for cold regions. In this cold region, the temperature should be above -12 degrees Celsius. Of course, it can also be used above 0 degrees. Many people bring long gas cylinders to cold regions without starting a stove, but flat gas cylinders can ignite, giving the impression that they are more stable.
Above, we said that flat gas cylinders are suitable for cold regions, but what about high-altitude regions? In fact, there is another type of gas, which is also a flat gas canister. Its fuel composition is a mixture of butane, propane, and isobutene. The butane here is from a long gas tank. What are the benefits of this gas? The benefits of mixing two gases. The advantage of butane is that it is cheap, but its gasification point is weak (only 0 degrees), while the gasification point of propane is very low (-42 degrees). After the fusion of these two gases, even in an environment of -40 degrees, propane can turn into gas, and then butane can be pushed out, and we can ignite the furnace normally.
