Anonymous users2024-01-24(1) There is still liquid in the bottle but it can't ignite, how does the liquid in the catheter come from; The reasons for the analysis may be: the temperature is low and the liquid is difficult to vaporize; Liquefied petroleum gas contains liquid impurities, and liquefied petroleum gas contains water;
Therefore, the answer is: it is difficult for liquids to vaporize at low temperatures; Liquefied petroleum gas contains liquid impurities, and liquefied petroleum gas contains water;
2) The books consulted should be books on the physical and chemical properties of liquefied petroleum gas; It can also be solved by going online, consulting experts, visiting liquefied petroleum gas companies, etc.;
Therefore, the answer is: about the physical and chemical properties of LPG; Go online, consult experts, visit LPG companies.
3) The main components of liquefied petroleum gas are propane, butane, propylene, butylene, etc., according to the boiling point data of several components, it can be known that the boiling point of butane and butene in liquefied petroleum gas is high, and it is not suitable for vaporization when the temperature is close to 0;
Therefore, the answer is: the boiling point of butane and butene in liquefied petroleum gas is high, and it is not suitable for vaporization when the temperature is close to 0.
4) If the residual droplets in the conduit are liquefied petroleum gas, they are flammable, which can be verified by taking a small amount of residual liquid and igniting it, and if the liquid burns, the above explanation is reasonable;
Therefore, the answer is: take a small amount of residual liquid and ignite it, if the liquid burns, it means that the above explanation is reasonable.
5) The temperature is low, and the LPG is not easy to vaporize, so it can be used in a ventilated place with a temperature higher than 10;
Therefore, the answer is: it is better to use it in a ventilated place with a temperature higher than 10.
1.After the LPG is used up, there is a residual liquid in the cylinder, the composition of which is (pentane), and some people find that the residual liquid can dissolve the grease, the reason is (organic matter can dissolve each other), so they pour it out as a detergent to wipe the oil. Is this practice of waste utilization advisable? >>>More
The liquefied petroleum gas in the kitchen is upright, and it should be placed in the corner of the kitchen, in a ventilated and dry place out of people's reach, and not let children touch it, which is very dangerous.
According to the specification, to wear a steel casing, the casing specifications should be two levels larger!
No, and the water heater should be balanced as much as possible.
Generally, it is necessary to separate at least one cabinet door, and there must be a solid plate in the middle.
