Paraffin wax was blended with F-T wax. The effects of the mass fraction of F-T wax on paraffin 46
# and 58
# were investigated respectively. The results show that the addition of F-T wax can significantly increase the melting point of paraffin, when the mass fraction of F-T wax increases from 0.05% to 30.00%, the melting point of 46
# and 58
# blended wax drops from 72.4 ℃ to 44.4 ℃, and drops from 88.4 ℃ to 62.4 ℃, respectively. With the increase of the mass fraction of F-T wax, the melting point and penetration of blended wax decrease continuously, that is, the mass fraction of F-T wax is inversely proportional to the drop melting point and penetration. The analysis of the crystalline structure of the blended wax shows that, the content of non-isoparaffins in the blended wax is higher. So its crystal structure is an array of inclined lattice arrangement of the long needlelike wax crystals, and the natural paraffin crystallization is different with others, which composition is more complex.
