Types Of Greases
Lithium, Calcium, Soda, Aluminium, Complex and Mixed soap base Greases, Soap free Grease, PTFE, Silicone and Molybdenum modified Greases, Specialty and Synthetic Greases.
Basic Defination
The original Definition of ASTM of Grease was "A solid or semi solid combination of petroleum products and a soap or mixtures of soaps with or without fillers, suitable for certain types of lubrication. Subsequent technological advances have led to the use of synthetic lubricating fluids on the one hand and non-soap thickeners on the other hand. Current - Modified Definition of Grease is "A solid or semi solid product of dispersion of thickening agent in liquid lubricant. Other ingredients imparting special properties may be included. Most greases are in fact is a combination of petroleum oils and metallic soaps. |
Grease is a lubricant of higher initial viscosity than oil, consisting originally of a calcium, sodium or lithium soap jelly emulsified with mineral oil. Greases are typically used in areas where a continuous supply of oil cannot be retained, such as open bearings or gears. Grease is a fine dispersion of an oil-insoluble thickening agent - usually soap in a fluid lubricant which is generally mineral lubricating oil. The soap is made up of fatty acid, tallow or vegetable oil saponified with alkali which can be hydrated lime, caustic soda, lithium hydroxide or aluminum hydroxide. The lubricating oil component is refined base oil-naphthenic, of medium viscosity index, or cylinder oil stock. Structurally grease is a water-in-oil emulsion. Its appearance is smooth, mostly translucent, soft or hard. Properties essential for performance of grease are structural stability, lubricating quality, low and high temperature performance (which are provided by the selected lube oil base stock), where as properties such as water resistance, high temperature quality, resistance to break down through continuous use and ability of grease to stay in place are provided by the soap. Additives e.g. Graphite, modified clay, asphalt, oxidation and corrosion inhibitors, extreme pressure additives molybdenum disulphide etc. are used to impart specific properties as required by end application. Factors to be considered when selecting greases are the type of grease, which in turn depends on operating temperatures, water resistance, oxidation stability etc. The second factor, no less important, are the grease's characteristics, including viscosity and consistency. |
The value of plastic lubricants has been recognized since very early times when animal fats were used for Axles and the like.
In general any lubricating fluid can be gelled by means of a suitable thickness to form a lubricating Grease. In practice mineral oils are almost exclusively used. For soap type Greases mineral oils of relatively low viscosity index 60 are preferred since the greater solvency of the more aromatic oils for soaps makes manufacture easier and gives greases with lower soap contents and with better properties.
Synthetic Fluids: Esters and silicones are used, only in greases for special applications, where cost is secondary to performance to meet low temperature and high temperature requirements; - 75C to + 320C. The Soaps used are the metallic salts of long chain fatty acids derived from wide range of natural fatty materials. Soaps are mainly produced by specifying the fat or fatty acid with appropriate alkali in the presence of oil. In some cases pre-formed soaps are used, such as aluminium stearate, lithium sterate etc. Non Soap Thickners may be inorganic e.g. silica or clay or organic with a very high melting point . e.g. terephthalamates, arylureas (these may be either pre-formed or formed in situ) and the dye stuffs, indanthrene and phthalscyanine. They need to be oleophilic and this characteristic may be imparted either in the thickner formulation (i.e. by including a long chain hydrocarbon chain or surface esterification ) or by coating the particle surfaces with organic cations. In the latter case about 75 percent of the particle surface is covered, which gives the desired effect without affecting inter particle forces too much. Pre-treated clays (i.e. coated and dried) need aids to facilitate dispersion in oil. These dispersion aids are low molecular weight polar organic compounds such as methanol, acetone, diacetone Alcohol and propylene Carbonate. A satisfactory Grease for a given application is expected to:
Soap Greases consist of dispersions of soap fibres in oil in concentrations mostly in the range 5 to 22%. By weight sometimes solid block greases contain 50 to 40% of soap. The thickeners in non-soap greases are usually particulate rather than fibrous in nature and in this case the structure is maintained by 3 dimensional linkages due to very short range inter particle forces (Vander waals forces). These linkages are readily broken and re-formed. |
Types Of Greases |
The metallic radical of the soap largely determines the characteristics of the greases the fatty radical having a secondary effect. Greases are therefore classified in terms of the metal they contain. |

What is Resin ?
Resins are film forming materials used in the production of paints and coatings. It binds the pigment particles into a coherent film that adheres to the substrate. The quality of the resin used in the production of paints and coating decides the durability of the paint. Resins are used depending upon the functional properties of the paint.
Functions of Resin:
To provide gloss and elasticity. | |
For the suspension of pigments. | |
To provide resistance to water, chemicals and abrasion. | |
Makes coating adhere to the surface. | |
Acts as a dispersant. | |
For drying properties. |
Alkyd resins from the largest group of synthetic resins are used in paint industry. Most air drying enamels are based on long or medium oil alkyd resins. These resins dry at room temperature and have excellent flow and leveling properties, good exterior durability and can be thinned with mineral turpentine. Oils used for producing alkyd resins are linseed oil, soybean oil and Dehydrated Castor Oil (DCO).
Plant Operations:
Frigmaires solvent based plant produces paints, coatings, stains, and surface treating products at a rate of about 1.1 million gal/yr. This paint manufacturing plants operations primarily involve blending and mixing of raw materials, product testing and packaging and cleaning of vessels and lines. Color separation of the product is done to befit customer specifications.
Water-based and solvent-based paints are mixed in different tanks from 200- to 1000-gal capacity. The material used in water-based paints include water, latex, resins, extenders, and dispersed pigments. For solvent-based paints, the materials are generally similar in type, but solvent replaces water and latex. Other ingredients used in this base include plasticizers, tints, and thinners.
After batches are made up, they are transferred to the let-down tanks. Additional water (or solvent), resins, preservatives, anti-foaming agents, thinners, and bactericides are added thereafter in the tanks. Batch testing encompasses checking color, viscosity and gloss. The material are then filtered and charged to cans for labeling, packaging, and shipping.
Waste Generation:
The principal waste streams are the result of equipment cleaning, especially from water-based paints. For example, rinsing the let-down tanks ordinarily requires about 35 gal of rinse water, but that amount increases to 53 gal if light paint is to be blended after dark paint. The hazardous nature of water rinses results from the mercury used as a bactericide in the paint.
The rinses are separated from the paints according to the color intensity. Waste rinses that are not reused are piped to holding and flocculation tanks, after that alum is added to lower the pH and flocculent is added to precipitate some solids. Finally, the supernatant liquid is removed for reuse in other paint formulations.
The tanks are rinsed with mineral spirits at a rate of about 5 gal/400-gal tank. There after, the washings are sent off-site for recovery, followed by recycling or sale as fuel.

What are Emulsions: | ||||||||||||||||||||||||||||||||||||||||||||||
Emulsions are solvent free binders used in the preparation of paints and coatings. These are produced by the polymerization process where monomers are dispersed in an aqueous phase to get a uniform and stable emulsion. Paints and coatings based on emulsion systems are best in performance and are environment friendly. Functions of Emulsion:
