浙江Fushun Kunlun brand 56 fully refined paraffin

The density of petroleum wax can be evaluated according to the value of the penetration degree of petroleum wax. The density is higher when the penetration degree is small, and the density is lower when the penetration degree is large. Oil wax needle into the size, but also can explain the oil wax thermal stability of good or bad. To some extent, the penetration degree of petroleum wax can be used to estimate the service characteristics and load bearing capacity of petroleum wax.

First, the main composition of paraffin

Paraffins are mainly composed of normal (straight chain) alkanes above C15, but also contain a small amount of isomeric alkanes or alkanes with long side chains.

Two, the melting point of paraffin

The melting point of paraffin wax is a main index to judge the grade of paraffin wax. For example, the melting point of No. 58 paraffin shall not be lower than 58℃ and no higher than 60℃.

Three, the stability of paraffin

Stability is divided into light stability and thermal stability.

The petroleum wax should have good heat and light stability. Otherwise, for a long time with hot air or direct sunlight, paraffin wax will gradually oxidize and deteriorate, the color becomes dark, and even the odor becomes large.
