The development trend of industrial smooth oil is the function of progressive products; especially the demand for the equipment proposed by the equipment manufacturer (OEM); the cost of reducing the product and the development of environmentally friendly products.
The development of smooth oil skills comes from two aspects. First, the quality of the base oil is improved through the improvement of the base oil production skills; second, the quality of the product is improved through the improvement of the smooth oil formula skills. In these two skills; The oil is the base.
(1) Improve the production process; improve the quality of the base oil.
Currently; the international smooth oil base oil is being converted from APII to APII/IIII; the base oil is produced in the positive hydrogenation technology. The smooth oil base oil produced by the hydrogenation skill; its sulfur, nitrogen and aromatic content is low; viscosity index High; good thermal oxidation stability; low volatility; long oil change period. International smooth oil hydrogenation base oil demand is gradually added; hydrogenation skills are rapidly developed. Estimated to 2005; global hydrogenation base oil consumption will account for base oil About 10% of the total. Polyalphaolefin composition oil (PAO) has a high viscosity index; excellent low temperature function and thermal oxidation stability; is selected in military and advanced internal combustion engines; but its price is constrained in industrial smooth Widely used in oil. In the 1990s; foreign developed the technology of producing smooth oil (GTL) from natural gas; it is the same as PAO, it is similar to alkanes; its function is close to it; the price after large-scale production is lower than PAO; A class of base oils with prospects.
(2) Carry out multi-functional additives.
Smooth oil additives are such chemicals; they are incorporated into a smooth oil base oil in a relatively small amount; that is, they can significantly improve certain properties of the smooth oil base oil; perhaps imparting a smooth oil base oil to some new ones that would not have been nature.
The use of smooth oil additives on the economic benefits of progressive smooth oil products and the achievement of certain specific skill indicators can not be ignored; even the key effect. There are many types of smooth oil additives; different types of additives have different functions. In order to reach the progress and balance of various functions; in a smooth oil formula, it is often necessary to participate in several or even dozens of additives; make the formula messy; increase the dosage and add the cost. Foreign countries are committed to multi-functional additives; will have no The same function "functional" is combined in the same molecule; after participating in an additive to reach a variety of functions. The most typical example is a thickener capable of tackifying, depressing and dispersing effects. In the smooth oil additive; Different additives can affect each other. For example; extreme pressure anti-wear additives are usually sulfur or phosphorus-rich compounds; they can form a sulphur-phosphorus compound film on the metal surface; reduce conflicts and avoid wear; but affect antioxidants and The effect of corrosion inhibitors is carried forward. Foreign countries are developing an additive that can reduce friction and improve the thermal oxidation stability of oil products.
(3) Improve the compound formula skills; reduce the amount of additives.
Modern industrial smooth oil production mostly uses compound additives for blending; not only the blending process is simple; and it can reduce the total dosage; save the cost. In the compounding skills; in addition to the use of multi-functional additives; it is important to discuss the synergy of additives Effect; the effect of the two additives when used together is much better than when using an additive alone; this can greatly reduce the total dosage of the additive. Reducing the total dosage of additives in industrial smooth oil is the quality of the oil. Amount and the important measure to reduce the cost. Current; the total dosage of anti-wear hydraulics has been reduced from 1.5% to 2.0% in the past to 0.4% to 0.6%, the total addition of industrial gear oil The dose is also reduced to less than 1.2%. The turbine oil is at the same dosage; the antioxidant life has been improved from the original 3000-4000 hours to more than 10,000 hours. The dosage of some single agents is also significantly reduced; In the past, it usually added 0. 05%-0. 1% demulsifier; now only need to participate in 0. 005% can have a good effect.
(4) Develop and apply new skills.
For human beings to have a better living environment; these years; international countries' demand for environmental protection and legislation is becoming more and more severe. Because of the leakage of equipment and the abandonment of smoothing agents; the pollution of industrial smoothing agents to the environment has now attracted the attention of the public. Non-toxic; biodegradable special smooth oil products have become the most sought-after research topic in the 21st century. The first part includes biological skills, nano skills and metal wear self-correcting skills. The application of biological skills in smooth oil is to discuss development. Biodegradable smooth oil products; such as biodegradable hydraulic oils, chain saw oils, two-stroke engine oils and smooth greases. The primary base oils for biodegradable smooth oils are vegetable oils and constituent ester oils. Currently used in vegetable oils. Most of them are low-acid rapeseed oil, high oleic sunflower oil, etc., which are composed of alcohol esters and fatty acid esters, complex esters, etc. Biodegradable smooth oil has outstanding smoothness and viscosity temperature function; High viscosity index; simple degradation into carbon dioxide and water in the air, these years; nanotechnology and data in the smooth category of the use of conflict technology The author attaches great importance to the use of smooth oil in nano-materials; the research on improving its anti-wear and anti-pressure functions has become a hot topic. There are currently two methods for preparing nano-material smooth oil; the first one is one-step method; In-situ composition method; it uses smooth oil as medium; directly forms nano data smooth data; and directly scatters in smooth oil; particle size is smaller than visible wavelength; therefore, the prepared smooth oil is clear, the second method is two steps Method; firstly prepare oil-soluble nano-smooth data; then disperse it into smooth oil. The amount of nano-materials in smooth oil can be freely modulated according to demand. Metal wear self-correction data (ART) is also a sought-after research topic. The effect mechanism is different from that of oily and extreme pressure additives or friction reducers; it does not form a film on the metal surface; nor does it generate an antifriction layer; instead, it directly attacks the chemical displacement reaction in the part where the conflict energy is converted into heat energy. Produce an organic or inorganic composite coating with excellent friction reduction and greatly improved microhardness; this will greatly improve the operation of the equipment. Lifespan. According to reports; use ART bearings; when the life reaches 21 times the use of the usual smooth oil; still can maintain the initial accuracy and clearance; basically no wear.
