        Lubricating oil for lubricating oil machine, also known as grease, so what is the specific classification of widespread use now?Let's see。
        (1) Lanzhou lubricating oil - soap-based grease。
        Lanzhou lubricating oilSoap-based grease accounts for about 90% of grease production。Widely used。.Commonly used greases are calcium base, sodium base, lithium base calcium sodium base, complex calcium base and so on。Composite aluminum base, composite lithium base grease also occupies a little proportion, these two kinds of fat are promising varieties。
        (2) Lanzhou lubricating oil - organic grease

        Various organic compounds thickened petroleum lubricants or hellanthes lubricants, each has its own characteristics, these greases are mostly used for purposes。For example, the high temperature grease made of Yindanshilin and phthalocyanine, which is afraid of thickening into lubricating oil, can be used for 200~ 250℃ working conditions;Greases made of polytetrafluoroethylene thickened fluorocarbons or perflurane carbons or perflurane, capable of strong oxidation and lubrication as components。For example, polyurea grease can be used for bearing lubrication under radiation-resistant conditions。

Lanzhou lubricating oil

        Polyurea grease of Lanzhou Lube oil is made of polyurea thickening agent thickened petroleum lubricating oil or synthetic lubricating oil, and has good temperature resistance。The consistency of fat has little change in the wide temperature range of 25~225℃。In addition, because there is no metal ion in the thickener molecule, the catalytic effect of metal on lubricating oil at high temperature is eliminated, so it has good oxidation stability.At 149℃, 10.Under the condition of 00r/min, the bearing life of urea grease is more than 4000 hours。Polyurea is a rapidly developing product in the past ten years, used in steel industry lubrication, food industry, power, electronics industry, long life seal bearing lubrication。
        (3) Lanzhou lubricating oil - inorganic grease
        Lanzhou lubricating oil mainly includes bentonite grease and silicone grease。Greases made of methicone thickened with calcium-silicone can be used for electrical insulation and vacuum sealing。Bentonite greases are made from surfactants such as dimethyl ammonium chloride or amino amides such as bentone434。Suitable for lubrication of automobile chassis, wheel bearings and high temperature bearings。Its characteristics are as follows: the bentonite grease of Lanzhou lubricating oil has no dripping point, its temperature resistance depends on the high temperature performance of the surfactant and the base oil, and its low temperature performance depends on the type of the selected base oil。The amount of thickening agent also affects the low temperature properties of fats。Colloidal stability is good, and the mechanical stability of greases varies according to the type of surfactant。Metal surfaces are slightly less resistant to corrosion。Therefore, anti-rust agents are added to the grease to improve this performance。
