Can mineral oil be used for chains operating at a high temperature of 260°C?
August 14, 2022
The lubricating oil used in the high temperature chain operating at 260°C is best to use synthetic oil. Some people will ask why they can't use the relatively cheap mineral oil. For this question, we must first understand the mineral oil. Mineral Oil Mineral oil is first refined from petroleum, which is made from the bottoms left over after crude oil has been fractionated into light substances. In essence, it is a poor composition in crude oil, so its high and low temperature performance is relatively inferior, and the pollution to the environment is relatively large.
Why can't it be used? Because it is used in high temperature chains, the temperature must be relatively high, and the maximum temperature of mineral oil is about 120 ° C, and the oxidation stability of mineral oil is extremely poor, and oxidation reaction occurs when it is more than 100 degrees. , coking and carbon deposition, and the volatility is also large. Therefore, in the case of 260 ℃, mineral oil can't play a role at all, only a large amount of carbon deposits will cause the chain to be stuck. High temperature chain oil It is not feasible to use mineral oil for high temperature chains at 260°C. It is recommended to use synthetic oil under such high temperature conditions. Synthetic high temperature chain oil can continuously lubricate and protect the chain under high temperature conditions of 260°C. The high temperature chain oil has a temperature resistance of up to 330 °C, has excellent high temperature performance and adhesion performance, has very little volatilization at high temperature, and does not form coke and carbon deposits, which is very suitable for chains operating at high temperatures.
