how lubricating grease is made?
14994
Lubricating grease is made by dispersing the thickener (solid phase) into the lubricating fluid (liquid phase) to form a stable product. In most cases, the thickener is the reaction product of carboxylic acid(s) and alkaline earth metal hydroxide(s), forming an organic salt, commonly referred to as a soap.

Products made from crude oil These petroleum products include gasoline, distillates such as diesel fuel and heating oil, jet fuel, petrochemical feedstocks, waxes, lubricating oils, and asphalt.

['Mineral oils – mineral oils are created as a result of refining crude oil and then improving their quality by adding certain substances. ... ', 'Fire resistant fluids – there are 4 main types. ... ', 'Water / oil emulsions – this is when the predominant substance (around 60%) is the oil.']

Some lubricants have a high acid content, which kills sperm. What's more, the lubricant's thick consistency makes it hard for sperm to move. This applies to both commercially available lubricants and homemade solutions such as coconut oil or saliva.

Chemical product that dissolves water-insoluble substances (such as greases and oils) from hard surfaces such as floor, machines, tools. Most heavy duty degreasers are made from hydrocarbon solvents such as kerosene and xylene.

Check it for compatibility with the base fluid used in the grease that is currently in service. ... This tells us two things, EP 2 grease is a NLGI Grade 2 and it is fortified with Extreme Pressure (EP) additives. This tells us nothing else about the thickener type, base oil type or viscosity of the base oil.

Use this general-purpose grease to lubricate most machinery. NLGI viscosity grade is a rating of a grease's consistency. NLGI 1 is about the consistency of tomato paste. Mineral-oil-based grease, derived from petroleum, is usually more economical than synthetic-oil-based grease.

Dielectric grease, or tune-up grease, is a silicone-based grease that repels moisture and protects electrical connections against corrosion. ... The grease does not conduct electricity, so it shouldn't be applied directly to the mating surfaces (pins and sockets) of an electrical connection.

jlindquist74: I'm being told that the common white lithium grease, which we used to lubricate VersaPlanetary gearboxes, does not adhere to gears well, and is the reason our VPs failed as much as they did. The red stuff is supposed to work better, supposedly it sticks to the metal better.

Nail polish is made by combining nitrocellulose and plasticizers with color pigments. The mixing is done in a "two-roll" differential speed mill, which grinds the pigment between a pair of rollers that are able to work with increasing speed as the pigment is ground down.

Most motor oils are made from a heavier, thicker petroleum hydrocarbon base stock derived from crude oil, with additives to improve certain properties. The bulk of a typical motor oil consists of hydrocarbons with between 18 and 34 carbon atoms per molecule.

Remove Baked on Grease If you have pans or trays with baked on grease try this awesome trick for removing it. You can add a mixture of hydrogen peroxide, dish soap, and baking soda to remove the baked on grease with little to no scrubbing. This is one of my favorite hydrogen peroxide tricks.

Summary. Soaps are surfactants, which means they dissolve in water and oils and can clean. Soapmaking involves reacting fats/oils with a strong hydroxide base, to form glycerin and soap (salts of fatty acids). Fat/oil molecules (triglycerides) are made up of glycerin chemically attached to 3 fatty acids.

Typically lubricants contain 90% base oil (most often petroleum fractions, called mineral oils) and less than 10% additives. Vegetable oils or synthetic liquids such as hydrogenated polyolefins, esters, silicones, fluorocarbons and many others are sometimes used as base oils.

Lubricating oil creates a separating film between surfaces of adjacent moving parts to minimize direct contact between them, decreasing frictional heat and reducing wear, thus protecting the engine. In use, motor oil transfers heat through conduction as it flows through the engine.

Friction is sometimes unhelpful. For example, if you don't lubricate your bike regularly with oil, the friction in the chain and axles increases. Your bike will be noisy and difficult to pedal. When there is a lot of friction between moving parts, energy is lost to the surroundings as heat.

Wax lube also keeps your bike chain cleaner than other kinds of lubes, as dirt and grit are “shed” from the wax compound. Don't lube your bike chain with WD-40. Only use lubricants designed specifically for use on bike chains. WD-40 is a solvent that evaporates quickly, and only contains a small amount of lubricant.
