Introduction to Paraffin
Paraffin is a common mineral wax obtained from petroleum fractions through a series of physical and chemical treatments. Due to its excellent physical properties such as high melting point, low volatility, and insulation performance, paraffin wax is widely used in multiple fields. This article will introduce the composition, properties, uses, and production methods of paraffin wax.
1¡¢ Composition of paraffin wax
The main component of paraffin is a mixture of hydrocarbons with carbon atoms between C16 and C35, which mainly includes straight chain alkanes and a small amount of branched alkanes. In addition, paraffin also contains small amounts of impurities such as cyclic hydrocarbons, aromatic hydrocarbons, colloids, and asphaltene.
2¡¢ Properties of paraffin wax
1. Physical properties
Paraffin is a white or slightly yellow translucent solid with a high melting point, typically between 70-90 ¡æ. The density of paraffin is relatively small, generally between 0.8-0.9g/cm 3. In addition, paraffin also has good electrical insulation properties, low water absorption, low volatility and other characteristics.
2. Chemical properties
Paraffin is a relatively stable compound that is not easily reacted with substances such as acids and bases. Under high temperature conditions, paraffin undergoes cracking and oxidation reactions, producing gases such as carbon, hydrogen, and oxygen. In addition, paraffin also has good chemical stability and can withstand certain pressures and corrosive environments.
3¡¢ The use of paraffin wax 1 Industrial lubricants, due to their low volatility, high viscosity, and high temperature resistance, can be widely used as industrial lubricants in fields such as steel, machinery, textiles, and chemicals. Especially in high-temperature lubricants, paraffin wax is widely used as a base oil and additive, which can meet the lubrication needs under harsh conditions such as high temperature, high pressure, and high load. 2. Paraffin wax is also an important raw material for candle manufacturing. Due to its good plasticity and ease of processing, paraffin can be processed into candles of various shapes and specifications. In addition, various spices and dyes are added during the candle manufacturing process to enhance the beauty and user experience of the candle. |
