The wax is a kind of mineral wax, also be a kind of petroleum wax; It comes from the lubricating oil fractions crude distillation income by solvent refined, solvent dewaxing or the wax frozen crystallization, squeezing dewaxing system cerate, again by solvent oil refining and took off the flake or needle crystal. Also called morphology wax, carbon atoms about 18 ~ 30 number of hydrocarbon mixtures, the main group is divided into linear paraffins (about 80% ~ 95%), and a small number of individual teams with linear alkanes and take long chain of the side chain of monocylic cycloparafin hydrocarbon (together content 20% below). Main quality index for melting point and oil content, the former heat-resistant ability, the latter said said the purity. Which two USES a wide before, mainly for food and other goods (such as wax paper, crayons, candles, carbon) components and packaging materials, roasted containers with dressing, cosmetic raw material, used for fruit fresh and improve rubber anti-aging sex and increase flexibility, electrical components insulation, precision casting, etc., can also be used to oxidation generating synthetic fatty acids.
