Processing of high erucic acid rapeseed oil

1. Used as a model lubricating oil for continuous cast steel Because high erucic oil contains polymerized long chains, it is conducive to the play of lubricity. Tests have shown that the high erucic oil is used as a lubricant for the steel mold, which has good lubrication performance and low oil consumption (113.4 to 170.1 g/ton). 2. Lubricating Oil Used as Mechanical Lubricant High erucic oil is mixed with mineral oil to make mixed oil. It is widely used in the lubrication of high-speed and high-pressure working machinery and has good results. 3. Quench oil used as metal heat treatment The high erucic acid oil has a high boiling point, a large heat capacity, is stable to heat, and has a slower polymerization and oxidation rate, and is a better quenching oil. It was determined that the quenching cooling rate of vegetable oil was 160°C/sec and the mineral oil was 100°C/sec. When the vegetable oil is properly treated and the water content is kept at 0.3%, the polymerization and oxidation can be delayed during quenching, thereby increasing the number of uses. 4. Additives used in the rubber industry High erucic acid oil reacts with sulfur to produce an elastic colloidal material for use in colloid erasers. Mixing the vulcanized vegetable oil with natural rubber or synthetic rubber at a high ratio produces a product with good elasticity, strong light resistance, and good oxygen resistance. Used in rubber compounds to increase the toughness of the product. It can also be used for rubber adhesives. 5. The hydrogenated fat used as a raw material for making waxes has a higher melting point than its hair fat and is close to the melting point of beeswax (62-65°C), but its hardness is higher than that of the latter. The liquid fatty wax can be prepared by the alcoholization of the unsaturated fatty acids in the high erucic oil with sodium reduction. Using this liquid for waxing and hydrogenation, another product can be made. Its melting point is 66-68°C, and its flexibility is higher than that of beeswax, which is similar to many industrial waxes. 6. Fuel used as a diesel engine Currently, there is a shortage of energy in the world. Using vegetable oil as fuel oil has been tested in many countries. For example, Sweden uses vegetable oil and mineral oil (50:50) as tractor fuel oil, and its power is unchanged. Other adverse effects. 7, other uses In the textile industry, vegetable oil as one of the textile lubricant formulations; in the electrical industry, vegetable oil for high temperature insulation oil; in the beneficiation industry, vegetable oil fatty acids can be used as a mineral flotation agent; in railway transportation, with As one of the formulas for the lubricating oil of railway vehicles. In addition, vegetable oil is also used as a component of grinding oil, metal wire drawing and metal cutting lubricants for steel gauges, and also used as a mold release agent for various molds (such as a brick mold release agent and a sand mold release agent).
