Paraffin wax is a colorless to white translucent lump. Pure paraffin is white, while paraffin containing impurities is yellow. It is tasteless, odorless, and greasy. Soluble in ether, chloroform, benzene, petroleum ether, volatile oil or various fatty oils, slightly soluble in ethanol. It has stable chemical properties and does not react with acids, alkalis, oxidants and reducing agents. It will turn yellow under ultraviolet irradiation, can burn and decompose, and is stable at room temperature. It is understood that paraffin wax is divided into crude paraffin wax, semi-refined paraffin wax, fully refined paraffin wax and food wax according to the degree of refining of paraffin wax. The deeper the degree of refining, the lighter the color and the better the product quality and the higher the production cost.
Crude paraffin refers to paraffin wax that has been sweated or deoiled by solvents but has not yet undergone the final refining process. In order to obtain paraffin wax with a high melting point, it needs to be refined again. Crude paraffin wax has a higher oil content and the product is darker in color. Due to the above reasons and other reasons, its quality is relatively poor compared with fully refined paraffin wax with the same melting point. Crude paraffin with a higher oil content has lower tensile strength and a softer and more brittle structure. It has good thermal stability, certain toughness and shrinkage.
Crude paraffin wax has the following applications:
Degraded use of various semi-refined wax applications;
Lubrication of various steel wire ropes Anti-rust;
Industrial petroleum jelly;
Emulsion explosive materials, industrial packaging paper;
Anti-corrosion demoulding of formed panels for construction;
Low-end candles, various combustion aids, frost-resistant thermal insulation of crops;
Particleboard and fiberboard moisture-proof;
Low-end hydrocarbon-based grease;
Low Lubricant for terminal PVC products
