Characteristics of some kinds of grease such as bentonite
Soap grease, grease grease production accounted for 90%, the most widely used. The most commonly used are calcium based, sodium based, lithium based, calcium based, complex calcium based grease. Composite aluminum base, composite lithium base grease also occupies a certain proportion, two kinds of fat are promising varieties.
Organic grease: any of various organic compounds thickened with petroleum, lubricating oils, or synthetic lubricants, each having different characteristics, most of which are used as a special purpose. Such as bronze thickening indanthrene phthalocyanine, synthesis of lubricating oil made of high temperature grease can be used to 200~250 DEG C; fluorine containing thickeners such as grease made of Teflon fluorocarbon or thickening Perfluoroethers, resistant to strong oxidizing agent, lubricant as special components. Polyurea lubricant, such as, can be used in the anti radiation conditions of bearing lubrication, etc..
Inorganic grease: mainly has two kinds of bentonite, grease and silica gel grease. Silicone grease is a kind of grease made of surface modified silica gel and condensed methyl silicone oil. It can be used in electrical insulation and vacuum sealing. Bentonite grease is composed of silicone grease table is composed of a surface active agent (e.g. two methyl eighteen alkyl benzyl ammonium chloride or amino acid) made of petroleum oil organic bentonite thickening after treatment of different viscosity or synthetic lubricating oil, suitable for automobile chassis, wheel bearing lubrication and high temperature of bearing.
Hydrocarbon grease grease made from ozokerite thickening oil base called hydrocarbon grease. With good plasticity, chemical stability and colloidal stability, insoluble in water, water does not produce emulsification. Its disadvantage is its low melting point, and alkyl grease is mainly used as a protective action.
