The Use of Paraffin Wax
Paraffin wax is a kind of mineral wax and also a kind of petroleum wax. It is a flake or needle crystal obtained by solvent refining, solvent dewaxing or wax freezing crystallization, solvent dewaxing to obtain a wax paste, and solvent deoiling and refining. Paraffin wax is also called crystal wax. It is a hydrocarbon mixture having a carbon number of about 18 to 30. Its main component is a linear alkane (about 80% to 95%), and a small amount of an alkane having an individual branch and a monocyclic naphthene having a long side chain (the total content of both is 20% or less). The main quality indicators are melting point and oil content. The former indicates temperature resistance and the latter indicates purity. It is widely used as a component and packaging material for food and other commodities (such as wax paper, crayons, candles, carbon paper), coating materials for baking containers, cosmetic raw materials, and for fruit preservation. It can also be used to improve rubber aging resistance and increase flexibility, electrical component insulation, precision casting and so on. It can also be used to oxidize to synthesize fatty acids.
Paraffin wax has many uses, mainly used in high-frequency porcelain, carbon paper, stylus wax paper, precision casting, decorative sound-absorbing panels and other products. It is also used in packaging, electronics, textile candle crayons, match manufacturing and other industries. In addition, it is also used in the manufacture of high-grade candles and various industrial, civil candle products and additives, modifiers and so on.
Fully refined paraffin and semi-refined paraffin are widely used. They are mainly used as ingredients and packaging materials for food, oral medicine and certain commodities (such as wax paper, crayons, candles, carbon paper), and coating materials for baking containers. They are also used for fruit preservation, electrical component insulation, improved rubber aging resistance and increased flexibility. They can also be used to oxidize to produce synthetic fatty acids.
