Industrial lubricants are widely used, and there are many types of base oils,
Such as: pure mineral oil, Pao poly ɑ Dilute hydrocarbon synthetic oil, polyether synthetic oil, alkylbenzene oil, biodegradable lipid oil. When they become a kind of industrial lubricant, they cannot be mixed with each other. For example, when polyether synthetic oil is mixed with other industrial oils, its performance will decline significantly.
Lubricating oil is generally composed of base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil. Additives can make up for and improve the shortcomings of base oil performance, give some new properties, and are an important part of lubricating oil.
Lube base oil
Lubricating oil base oil is mainly divided into three categories: mineral base oil, synthetic base oil and vegetable oil base oil. Mineral base oil is widely used, with a large amount (about 95% or more), but synthetic base oil or vegetable oil (bio based) base oil is used in some applications.
Additives are the essence of modern high lubricating oil. Correct selection and reasonable addition can improve its physical and chemical properties, endow lubricating oil with new special properties, or strengthen its original performance to meet higher requirements. Therefore, these two base oils have developed rapidly.
Industrial lubricants have different additives in different applications. The hydraulic oil used outdoors should be suitable for the local temperature change, and the hydraulic oil used indoors in a closed environment cannot be used. In addition, the use conditions of heavy-duty gear oil and forming oil are also different. Heavy-duty gear oil contains extreme pressure additives to ensure that it can be used in harsh environments. Forming oil, usually pure mineral oil, does not contain additives.
Industrial lubricants include a wide variety of lubricants and practical applications. Although there are many varieties and numerous examples, its main varieties, such as steam turbine oil, bearing lubricant, hydraulic oil, gear oil, machine tool lubricant, grease, metalworking fluid, textile lubricant, quenching oil, heat transfer oil, electrical oil, refrigeration oil, rust proof oil, etc., are widely used in industry and are generally familiar to people.
We make the following selection standards for the performance of industrial lubricants
Viscosity: viscosity is of decisive significance to the identification and determination of oil quality;
Flash point: flash point is the safety index of industrial lubricating oil during storage, use and transportation, and can also be used as the index of lubricant volatility;
Pour point: it can indirectly prove the important index of low temperature fluidity of lubricating oil during storage, use and transportation;
Performance indicators: due to many performance indicators, the performance gap between different industrial lubricants is very wide. We should make a reasonable and economic judgment in combination with the actual situation at that time;
