| [Visitor (23.83.*.*)]answers [Chinese ] | Time :2020-07-07 | Paraffin is a mixture of hydrocarbons, so it does not have a strict melting point like a pure compound. The so-called melting point of paraffin refers to the temperature at which the stagnation period appears for the first time on the cooling curve when the melted paraffin sample is cooled under prescribed conditions. All wax products require good temperature resistance of paraffin wax, that is, they do not melt or soften at a specific temperature. According to the conditions of use, the region and season of use, and the difference in the environment of use, commercial paraffins are required to have a series of different melting points.
The main factor affecting the melting point of paraffin wax is the weight of the raw material fraction selected, and the melting point of paraffin wax removed from the heavier fraction is higher. In addition, the oil content also has a great influence on the melting point of paraffin. The more oil in the paraffin, the lower the melting point. |
