What is the meaning of turpentine is what

The turpentine, mainly pine trees or pine trunks secreted resin, containing rosin and turpentine. It is also known as rosin, pine paste, pine gum, pine liquid and pine fat. Its special chemical structure, can be used as latex paint and adhesive and other materials, so the resin has a high commercial value. It is a mixture of many polymer compounds, so it has different melting points. Resin can be categorized into two types: natural resin and synthetic resin. There is only one type of resin, but with the development of chemical industry, there are many synthetic polymers, some of which are very similar to natural resins in terms of chemical and physical properties, and therefore, the polymers are called synthetic resins. They are viscous liquids or lumpy solids in air. Its special chemical structure makes it commercially valuable as a material for latex paints and adhesives. The two main processing methods for turpentine in China are the steam method and the direct fire method.
