AEROSOLS |
|
Aerosol spray is the name given to a type of canister containing liquid under pressure from pressurized vapor in equilibrium with another liquid, which often also dissolves the payload (see propellant below). When the can's valve is opened, the liquid is forced out of a small hole and emerges as an aerosol, or mist. As gas expands to drive out the payload, some propellant evaporates inside the can to maintain an even pressure. Outside the can, the droplets of propellant evaporate rapidly, leaving the payload suspended as very fine particles or droplets. Typical liquids dispensed in this way are insecticides, deodorants and paints. An atomiser is a similar device that is pressurised by a hand-operated pump rather than by stored gas.

CLOTHING / GARMENT / APPAREL |
|
Clothing is defined, in its broadest sense, as coverings for the torso and limbs as well as coverings for the hands (gloves), feet (socks, shoes, sandals, boots) and head (hats, caps). Humans nearly universally wear clothing, which is also known as dress, garments, attire, or apparel. People wear clothing for functional as well as for social reasons. Clothing protects the vulnerable nude human body from the extremes of weather and other features of our environment. But every article of clothing also carries a cultural and social meaning.

COATINGS |
|
A coating is a covering that is applied to an object to protect it or change its appearance. They may be applied as liquids, gases or solids.
Examples of coatings:
Anodizing
Chemical vapor deposition and physical vapor deposition
Chromate conversion coating
Enamel (paint)
Industrial coating
Oxide (coating)
Paint
Plasma coatings
Electroless plating or electrochemical plating
Phosphate (coating)
Polymer coatings, such as Teflon
Sputtered or vacuum deposited materials
Plate steel is often ordered from the mill pickled and oiled)
Enamel (vitreous)
Fusion bonded epoxy coating (FBE coating)

CORROSION EVALUATIONS |
|
Corrosion is deterioration of intrinsic properties in a material due to reactions with its environment. Weakening of steel due to oxidation of the iron atoms is a well-known example of electrochemical corrosion. This type of damage usually affects metallic materials, and typically produces oxide(s) and/or salt(s) of the original metal. Corrosion also includes the dissolution of ceramic materials and can refer to discoloration and weakening of polymers by the sun's ultraviolet light.

HORSES |
|
The horse (Equus caballus or Equus ferus caballus) is a sizeable ungulate mammal, one of ten modern species of the genus Equus. Horses have long been one of the most economically important domesticated animals, and have played an important role in the transport of people and cargo for thousands of years. Most notably, horses can be ridden by a person perched on a saddle attached to the animal, and are also widely harnessed to pull objects like wheeled vehicles or plows. In some human cultures, horses are also widely used as a source of food. Though isolated domestication may have occurred as early as 4500 BC, clear evidence of widespread use by humans dates to no earlier than 2000 BC, as evidenced by the Sintashta chariot burials, thus firmly establishing the domestication of the horse.

PAINT |
|
Paint is the general term for a family of products used to protect and add color to an object or surface by covering it with a pigmented coating. As a verb, painting is the application of paint. One who paints is called a painter.

PHOTOGRAPHY |
|
Photography is the process of making pictures by means of the action of light. It involves recording light patterns, as reflected from objects, onto a sensitive medium through a timed exposure. The process is done through mechanical, chemical or digital devices commonly known as cameras.
The word comes from the Greek words φως phos ("light"), and γραφις graphis ("stylus", "paintbrush") or γραφη graphê, together meaning "drawing with light" or "representation by means of lines" or "drawing." Traditionally, the product of photography has been called a photograph. The term photo is a convenient abbreviation. Many people also call them pictures. In digital photography, the term image has begun to replace photograph. This term is neither more nor less correct than photograph, either in film or digital photography. (The term image is traditional in geometric optics.)

PLASTICS |
|
Plastic covers a range of synthetic or semisynthetic polymerization products. They are composed of organic condensation or addition polymers and may contain other substances to improve performance or economics. There are few natural polymers generally considered to be "plastics". Plastics can be formed into objects or films or fibers. Their name is derived from the fact that many are malleable, having the property of plasticity. Plastics are designed with immense variation in properties such as heat tolerance, hardness, resiliency and many others. Combined with this adaptability, the general uniformity of composition and light weight of plastics ensures their use in almost all industrial segments.
