What is a lubricant : A lubricant is an agent (liquid, semi-solid, solid, gas) interposed between two moving surfaces to reduce friction
Basic Lubrication Concepts : Lubrication can be a daunting obstacle to someone unfamiliar with its basic concepts. Even someone with experience can be confused by the technology of current machinery combined with the multitude of lubricants available on the market today. Reviewing a few of the basic principles of lubrication can make it easier to see why proper lubrication is necessary in every application.
Friction : Webster defines friction as the "rubbing of one body against another," and as "resistance to relative motion between two bodies in contact." Friction can be beneficial. As we overcome this resistance to motion between two objects in contact, heat is generated. This heat is what warms our hands or starts a fire. Friction is also the principle behind the braking systems we find on our automobiles. In fact, once we were able to get a car moving, there would be nothing to stop it without friction except the effects of gravity or other objects.
However, friction can also be our enemy. The heat generated as the result of friction can cause damage. Because contact is required to generate friction, wear in the areas of contact can occur. This can lead to material failures, overheating and the formation of wear deposits.
Although there are many ways to reduce friction, the most common way is through the use of a fluid or semi-fluid material. The key characteristic of such materials is that they are not readily compressible. Fluid and semi-fluid materials allow us to minimize component contact or eliminate contact altogether. These fluids are commonly referred to as lubricants.
Types of lubrication : There are three types of lubrication or lubrication situations that can exist between two surfaces separated by a lubricant. Whether or not these situations occur is dependent upon the ability of the lubricant to provide adequate protection to the moving surfaces.
When a fluid lubricant is present between two rolling and/or sliding surfaces, a thicker pressurized film can be generated by the movement of the surfaces (at their respective velocities). The non-compressible nature of this film separates the surfaces and prevents any metal-to-metal contact. The condition in which surfaces are completely separated by a continuous film of lubricating fluid is commonly referred to as Hydrodynamic or Full fluid film lubrication.
Although hydrodynamic lubrication is the ideal lubrication scenario, in many situations it cannot be maintained. Hydrodynamic lubrication is limited by the lubricants viscosity, the rotation speed or RPM and by component loading. An increase in speed or viscosity increases oil film thickness. An increase in load decreases oil film thickness.
Boundary Lubrication is a condition in which the lubricant film becomes too thin to provide total surface separation. This may be due to excessive loading, low speeds or a change in the fluids characteristics. In such a case, contact between surface asperities (or peaks and valleys) occurs. Friction reduction and wear protection is then provided via chemical compounds rather than through properties of the lubricating fluid.
The third type of lubrication situation is known as Elasto hyro dynamic Lubrication (EHD or EHL). This situation occurs as pressure or load increases to a level where the viscosity of the lubricant provides a higher shear strength than the metal surface that it supports.
Our clients can avail from us a wide array of Coolant Plant.
Antifreeze differ from engine coolant : Engine coolant is a generic term used to describe fluids that remove heat from an engine. Antifreeze is a more specific term used to describe products used to provide protection against freezing. Many people use these terms interchangeably.
Antifreeze prevents engine’s cooling system from freezing in the winter, what else does antifreeze do for engine’s cooling system :
- Antifreeze (engine coolant) performs several functions in addition to providing freeze protection
- It contains chemicals that inhibit corrosion and scale formation in the engine and radiator
- This (engine coolant) provides protection against boiling in the summer. At one atmosphere pressure pure water boils at 212 °F (100 °C) but a 50/50 blend of water/ethylene glycol boils at 223 °F (106 °C)
Working of the cooling system : The cooling system removes excess heat from the engine block and heads, keeps the engine operating at its most efficient temperature, and gets the engine up to the correct temperature as soon as possible after starting. Ideally, the cooling system keeps the engine running at its most efficient temperature no matter what the operating conditions are.
Environmental issues require cleaner burning engines. Engine manufacturers have raised engine operating temperatures in order to reduce exhaust emissions and improve fuel economy. Today’s engines run on the borderline of overheating, with in-cylinder combustion temperatures around 2,000 °F. As fuel is burned in the engine, about one-third of the energy in the fuel is converted to kinetic energy for moving the vehicle. Another third goes out the exhaust pipe and the remaining third is removed by the cooling system. If no cooling were provided, metal parts would melt and the pistons would seize. The engine coolant must have indirect contact with the combustion chamber, the cylinder walls, and the valve seats and guides. As the engine coolant circulates through the engine, it picks up heat from the engine. The coolant releases this heat as it passes through the radiator.

Brake Fluid Plant
We are instrumental in providing to our valuable customers excellent quality of Brake Fluid Plant. Brake fluid is a type of hydraulic fluid used in hydraulic brake applications in motorcycles, automobiles, light trucks, and some advanced bicycles. It is used to transfer force under pressure from where it is created through hydraulic lines to the braking mechanism near the wheels. It works because liquids are not appreciably compressible. Braking applications produce a lot of heat, so brake fluid must have a high boiling point to remain effective, and must also not freeze under normal temperatures. These requirements eliminate most water-based solutions.
Brake fluid comes in a number of forms, and is standardized worldwide by the United States Department of Transportation (Dot). Dot 2 is essentially castor oil; Dot 3, Dot 4, and Dot 5.1 are composed of various mineral oils, glycol esters, and ethers; some are synthetic oil based, and Dot 5 is silicone-based. As of 2006, most cars produced in the U.S. use DOT 3
Some very old British cars use Girling brakes, which are incompatible with DOT 3 brake fluid. British-car dealers are careful in observing this precaution; but UK law does not require such observations be taken by commercial garages.
Glycol based fluids are half as compressible as silicone type fluids, even when heated]. Less compressibility of brake fluid will increase pedal feel (firmness), but in either case this effect is minimal. The U.S. Army has used silicone brake fluid exclusively since 1982 successfully. Glycols are hygroscopic and will absorb water from the atmosphere, reducing the boiling point of the fluid and degrading hydraulic efficiency. Changing fluid on a regular basis will greatly increase the performance of the brake system, but this is often not a concern in passenger cars. On the other hand, changing fluid at least every several years will preserve the life of brake system components (by removing accumulated water and other contaminants, thereby reducing rust on internal components), and increase the overall reliability of the brake system.
Polyethylene glycol, and other brake fluid ingredients may be corrosive to paint and finished surfaces such as chrome, and thus care should be taken when working with the fluid. Additionally, polyethylene glycol, in the concentrations found in DOT brake fluids, reacts violently, producing a large fireball, with some household chemicals, notably pool care products.

There has been a need since ancient times for lubricating greases. The egyptians used mutton fat and beef tallow to reduce axle friction in chariots as far back as 1400 BC. More complex lubricants were tried on ancient axle hubs by mixing fat and lime, but these crude lubricants were in no way equivalent to the lubricating greases of modern times. Good lubricating greases were not available until the development of petroleum-based oils in the late 1800's. Today, there are many different types of lubricating greases, but the basic structure of these greases is similar.
In general, grease consists of a thickening agent dispersed throughout lubricating oil. The thickening agents or gallants include alkali metal soaps, clays, polymers, carbon black, colloidal silica and aluminum complexes. The lubricating oil may be petroleum oil or synthetic oil. The most common type of grease is the soap-based grease. The soap comes from animal or vegetable fats or fatty acids, wool grease, rosin or petroleum acids. The lubricating oil is commonly mineral oil from paraffinic, naphthenic or aromatic hydrocarbons. Other components of these greases include unreacted fat, fatty acids and alkali, unsaponifiable matter (including glycerol and fatty alcohols), rosin or wool grease and water. Some of the other additives used in grease are oxidation inhibitors, rust and corrosion inhibitors, color stabilizers, metal passivators, water repellants and viscosity index improvers.
In soap greases the metallic soap consists of a long-chain fatty acid neutralized by a metal such as aluminum, barium, calcium, lithium, magnesium, sodium or strontium. The fatty acids usually contain 16 to 18 carbon atoms. A common form of soap-based grease uses lithium 12-hydroxystearate as the thickener. To properly thicken the grease the soap must be in the form of fibers of suitable size dispersed throughout the lubricating oil. The crystalline fibers are usually in the size range of 1-100 micrometers with diameters 0.1 to 0.01 of their length. For good shear stability the fiber should have a large ratio of length to diameter, and for good oil retention the fiber should be as small as possible. Therefore, greases need a mixture of these two types of fibers. Also, there must be a balance between the solvency of the fluid and the solubility of the soap to get suitable thickening.
Another type of thickener that is not soap-based is prepared from clays. The clay, such as bentonite or attapulgite, is reacted with a quaternary amine to change the clay from hydrophilic (water-loving) to hydrophobic (water-rejecting) and oleophilic (attracting oil). Effective thickening is achieved by combining the clay with a polar activator or dispersant, such as acetone, methanol or ethanol, with small amounts of water and by delaminating and reducing the platelets to a small size. This process will increase the total surface area of the dispersed clay, which immobilizes a very high percentage of oil based on the weight of clay. This will thicken the grease.
