Lubricant
A lubricant (sometimes shortened to lube) is a substance that helps to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces. The property of reducing friction is known as lubricity. In addition to industrial applications, lubricants are used for many other purposes. Other uses include cooking (oils and fats in use in frying pans, in baking to prevent food sticking), bioapplications on humans (e.g. lubricants for artificial joints), ultrasound examination, medical examination, and sexual intercourse. It is mainly used to reduce friction and to contribute to a better and efficient functioning of a mechanism. History Lubricants have been in some use for thousands of years. Calcium soaps have been identified on the axles of chariots dated to 1400 BC. Building stones were slid on oil-impregrated lumb ...

Dry Lubricant
Dry lubricants or solid lubricants are materials that, despite being in the solid phase, are able to reduce friction between two surfaces sliding against each other without the need for a liquid oil medium. The two main dry lubricants are graphite and molybdenum disulfide. They offer lubrication at temperatures higher than liquid and oil-based lubricants operate. Dry lubricants are often used in applications such as locks or dry lubricated bearings. Such materials can operate up to 350 °C (662 °F) in oxidizing environments and even higher in reducing / non-oxidizing environments (molybdenum disulfide up to 1100 °C, 2012 °F). The low-friction characteristics of most dry lubricants are attributed to a layered structure on the molecular level with weak bonding between layers. Such layers are able to slide relative to each other with minimal applied force, thus giving them their low friction properties. However, a layered crystal structure alone is not necessa ...

Grease (lubricant)
Grease is a solid or semisolid lubricant formed as a dispersion of thickening agents in a liquid lubricant. Grease generally consists of a soap emulsified with mineral or vegetable oil. A common feature of greases is that they possess a high initial viscosity, which upon the application of shear, drops to give the effect of an oil-lubricated bearing of approximately the same viscosity as the base oil used in the grease. This change in viscosity is called shear thinning. Grease is sometimes used to describe lubricating materials that are simply soft solids or high viscosity liquids, but these materials do not exhibit the shear-thinning properties characteristic of the classical grease. For example, petroleum jellies such as Vaseline are not generally classified as greases. Greases are applied to mechanisms that can be lubricated only infrequently and where a lubricating oil would not stay in position. They also act as sealants to prevent ingress of water and incompressible materia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Personal Lubricant
Personal lubricants (colloquially termed lube) are specialized lubricants used during sexual acts, such as intercourse and masturbation, to reduce friction to or between the penis and vagina, anus or other body parts or applied to sex toys to reduce friction or to ease penetration. Surgical or medical lubricants or gels, which are similar to personal lubricants but not usually referred to or labelled as "personal" lubricants, may be used for medical purposes such as speculum insertion or introduction of a catheter. The primary difference between personal and surgical lubricants is that surgical lubricants are thicker, sterile gels, typically containing a bacteriostatic agent. As of 2015 the personal lubricant market was estimated to be worth at least $400 million. Types By composition Water-based Water-based personal lubricants are water-soluble and are the most widely used personal lubricants. The earliest water-based lubricants were cellulose ether or glycerin solutions. Pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social Lubricant
The term social lubricant is any food, beverage, drug or activity that stimulates social interactions or helps people feel more comfortable in social occasions. Different cultures use different social lubricants for this purpose. Some common social lubricants are: * Humor is the most prevalent social lubricant spanning all cultures and age groups. * Alcoholic beverages (beer in pub culture, or wine in wine bars, for example) * Coffee (in coffee cultures, for example) * Tea (at tea parties, for example) * Tobacco (in cigarettes or a hookah, for example) * Small Talk (informal discourse or conversation, for example) The earliest known usage of the term can be found in Steve Allen's book, "How to be Funny". In the introduction he writes, "Humor is a social lubricant that helps us get over some of the bad spots." {{cn, date=January 2020 The term social lubricant appears on page 110 of the book titled " Alcoholics Anonymous" in the chapter "To Wives”: "We know all about liquor as ...

Surgical Lubricant
Surgical lubricants, or medical lubricants, are substances used by health care providers to provide lubrication and lessen discomfort to the patient during certain medical and surgical procedures such as vaginal or rectal examinations. Some example of surgical compatible lubricants are: * Surgilube is a surgical lubricant made of natural water-soluble gums that also contains the antiseptic chlorhexidine gluconate. * K-Y Jelly was initially used as a surgical lubricant before it gained popularity as a personal lubricant. * Lignocaine gel containing the local anaesthetic lignocaine is a prime example of a non-irritating substances used as surgical lubricant * Medicinal castor oil was the original vegetable-based surgical lubricant. * Indications for medical lubricants: Sjögren syndrome, specifically for treating vaginal dryness, dyspareunia (painful sexual intercourse) and vulvodynia Vulvodynia is a chronic pain syndrome that affects the vulvar area and occurs without an ...
