Paraffin is a kind of mineral wax!

Paraffin wax is a kind of mineral wax, but also a kind of petroleum wax; It is a flake or needle crystal obtained from the lubricating oil fraction obtained by distillation of crude oil by solvent refining, solvent dewaxing or wax freezing crystallization, press dewaxing, and then solvent deoiling, refining and wax paste. Also known as crystal wax, carbon atom number is about 18 ~ 30 of the hydrocarbon mixture, mainly divided into straight chain alkanes (about 80% ~ 95%), there are a small number of individual branch chain alkanes and long side chain of the single ring cycloalkanes (the total content of both below 20%). The main quality indicators are melting point and oil content, the former means temperature resistance, the latter means purity.

White oil is usually classified according to the purity of its saturated hydrocarbons. Industrial white oil is commonly used, which is suitable for chemical fiber aluminum processing, rubber plasticizing and other oils, and is also suitable for textile machinery, precision instrument lubrication and compressor sealing oil; Cosmetic grade white oil, suitable for making cosmetic industry raw materials, hair lotion, hair oil, lip balm, skin care fat, etc. Also used in food, pesticides. Food grade white oil is suitable for food glazing, anti-sticking, de-coating, defoaming, sealing, polishing, food machinery, surgical instruments rust, lubrication and prolong the storage life of wine vinegar, fruits, vegetables, cans, etc.

The paraffin products produced are classified according to varieties, including fully refined paraffin wax, semi refined paraffin wax, food and food processing paraffin wax, microcrystalline wax, vaseline, various special waxes and special waxes. Such as wax for automobile, wax for electronic industry, rubber protective wax, temperature sensitive wax, oxidized microcrystalline wax, wax based hot melt adhesive, wax for explosive industry, etc. There are many kinds of waxy crude oil in China, and petroleum wax resources are abundant. According to statistics, the output of finished paraffin wax in 2005 has reached 154 * 104t, and its output and export volume have respectively reached 37% and 47% of the world's total output, becoming the largest country in paraffin wax production and export in the world. Although the output of paraffin wax in China is large, the product structure is unreasonable. The output of special wax products with high added value is very low, accounting for only 0% of the output of paraffin wax. About 5%, much lower than the total output of 93 * 104t/a paraffin wax, and the special wax and special wax products account for 30% of the total output of the United States.
