Cleaning Products
Cleaning is the process of removing unwanted substances, such as dirt, infectious agents, and other impurities, from an object or environment. Cleaning is often performed for beauty, aesthetic, hygiene, hygienic, Function (engineering), functional, safety, or environmental protection purposes. Cleaning occurs in many different contexts, and uses many different methods. Several occupations are devoted to cleaning. Contexts Cleaning occurs in various commercial, domestic, personal, and environmental contexts, which differ in scale and requirements. * Commercial cleaning, in business or other commercial settings ** Terminal cleaning, in healthcare settings * Housekeeping, including spring cleaning * Hygiene, including personal grooming * Environmental remediation, the removal of pollution or contaminants from the natural environment Methods Cleaning is broadly achieved through mechanical action and/or chemical processes (usually solvation); many methods rely on a combination of m ...

Washing
Washing is a method of cleaning, usually with water and soap or detergent. Regularly washing and then rinsing both body and clothing is an essential part of good hygiene and health. Often people use soaps and detergents to assist in the emulsification of oils and dirt particles so they can be washed away. The soap can be applied directly, or with the aid of a Towel, washcloth or assisted with Sponge (tool), sponges or similar List of cleaning tools, cleaning tools. In social contexts, washing refers to the act of bathing, or washing different parts of the body, such as Hand washing, hands, Hair washing, hair, or Face washing, faces. Excessive washing may damage the hair, causing dandruff, or cause rough skin/skin lesions. Some washing of the body is done ritually in religions like Christianity and Judaism, as an Ritual purification, act of purification. Washing can also refer to washing objects. For example, laundry, washing of clothing or other cloth items, like bedsheets, or Di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemical Process
In a scientific sense, a chemical process is a method or means of somehow changing one or more chemicals or chemical compounds. Such a chemical process can occur by itself or be caused by an outside force, and involves a chemical reaction of some sort. In an "engineering" sense, a chemical process is a method intended to be used in manufacturing or on an industrial scale (see Industrial process) to change the composition of chemical(s) or material(s), usually using technology similar or related to that used in chemical plants or the chemical industry. Neither of these definitions are exact in the sense that one can always tell definitively what is a chemical process and what is not; they are practical definitions. There is also significant overlap in these two definition variations. Because of the inexactness of the definition, chemists and other scientists use the term "chemical process" only in a general sense or in the engineering sense. However, in the "process (engine ...

Sound Wave
In physics, sound is a vibration that propagates as an acoustic wave through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the ''reception'' of such waves and their ''perception'' by the brain. Only acoustic waves that have frequencies lying between about 20 Hz and 20 kHz, the audio frequency range, elicit an auditory percept in humans. In air at atmospheric pressure, these represent sound waves with wavelengths of to . Sound waves above 20 kHz are known as ultrasound and are not audible to humans. Sound waves below 20 Hz are known as infrasound. Different animal species have varying hearing ranges, allowing some to even hear ultrasounds. Definition Sound is defined as "(a) Oscillation in pressure, stress, particle displacement, particle velocity, etc., propagated in a medium with internal forces (e.g., elastic or viscous), or the superposition of such propagated oscillation. (b) Auditory sens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acoustic Cleaning
Acoustic cleaning is a maintenance method used in material-handling and storage systems that handle bulk granular or particulate materials, such as grain elevators, to remove the buildup of material on surfaces. An acoustic cleaning apparatus, usually built into the material-handling equipment, works by generating powerful, audible sound waves which shake particulates loose from surfaces, reducing the need for manual cleaning. Higher frequency sound waves are used in Ultrasonic and Megasonic cleaning History and design An acoustic cleaner consists of a sound source similar to an air horn found on trucks and trains, attached to the material-handling equipment, which directs a loud sound into the interior. It is powered by compressed air rather than electricity so there is no danger of sparking, which could set off an explosion. It consists of two parts: *The acoustic driver, usually made from solid machined stainless steel. In the driver, compressed air escaping past a di ...

Abrasive Blasting
Sandblasting, sometimes known as abrasive blasting, is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface or remove surface contaminants. A pressurised fluid, typically compressed air, or a Centrifugal force, centrifugal wheel is used to propel the blasting material (often called the ''media''). The first abrasive blasting process was patented by Benjamin Chew Tilghman on 18 October 1870. There are several variants of the process, using various media; some are highly abrasive, whereas others are milder. The most abrasive are shot blasting (with metal shot (pellet), shot) and sandblasting (with sand). Moderately abrasive variants include glass bead blasting (with glass beads) and plastic media blasting (PMB) with ground-up plastic stock or walnut shells and corncobs. Some of these substances can cause anaphylactic shock to individuals allergic to the media ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wet Cleaning
Wet cleaning refers to methods of professional cleaning that, in contrast to traditional dry cleaning, avoids the use of organic solvents, the most common of which is tetrachloroethylene (commonly called perchloroethylene or "perc"). Proponents of wet cleaning state that these methods can be used without shrinking or otherwise damaging garments that typically require dry cleaning. Computer-controlled wet cleaning machines, special dryers, detergents and spot removers make wet cleaning an environmentally sound method. Wet cleaning machines have controls that allow them to safely and efficiently clean a wide variety of garments in water. Equipment, detergents and skill all contribute to successful wet cleaning. The specialized detergents and conditioner used in the wet clean process are milder than home laundry products. All of the products are disposed of down the drain and are easily handled by the local waste water treatment facility. For professional cleaners, wet-cleaning is ...

Pressure Washing
Pressure washing or power washing is the use of high-pressure water spray to remove loose paint, mold, grime, dust, mud, and dirt from surfaces and objects such as buildings, vehicles and concrete surfaces. The volume of a mechanical pressure washer is expressed in gallons or liters per minute, often designed into the pump and not variable. The pressure, expressed in pounds per square inch, Pascal (unit), pascals, or Bar (unit), bar, is designed into the pump but can be varied by adjusting the unloader valve or using specialized nozzle tips. Machines that produce pressures from 750 to 30,000 pounds per square inch, psi (5 to 200 MPa) or more are available. The terms pressure washing and power washing are used interchangeably in many scenarios, and there is some debate as to whether they are actually different processes. An industrial pressure washing surface cleaner is a tool consisting of two to four high-pressure jets on a rotating bar that swivels when water is flowing. Som ...

Wet Wipe
A wet wipe, also known as a wet towel, wet one, moist towelette, disposable wipe, disinfecting wipe, or a baby wipe (in specific circumstances) is a small to medium-sized moistened piece of plastic or cloth that either comes folded and individually wrapped for convenience or, in the case of dispensers, as a large roll with individual wipes that can be torn off. Wet wipes are used for cleaning purposes like personal hygiene and household cleaning; each is a separate product depending on the chemicals added and medical or office cleaning wipes are not intended for skin hygiene. In 2013, owing to increasing sales of the product in affluent countries, Consumer Reports reported that efforts to make the wipes "flushable" down the toilet had not entirely succeeded, according to their test. Invention American Arthur Julius is seen as the inventor of wet wipes. Julius worked in the cosmetics industry and in 1957, adjusted a soap portioning machine, putting it in a loft in Manhattan ...

Paper Towel
A paper towel is an absorbent, disposable towel made from paper. In Commonwealth English, paper towels for kitchen use are also known as kitchen rolls, kitchen paper, or kitchen towels. For home use, paper towels are usually sold in a roll of perforated sheets, but some are sold in stacks of pre-cut and pre-folded layers for use in paper-towel dispensers. Unlike cloth towels, paper towels are disposable and intended to be used only once. Paper towels absorb water because they are loosely woven, which enables water to travel between the fibers, even against gravity ( capillary effect). They have similar purposes to conventional towels, such as drying hands, wiping windows and other surfaces, dusting, and cleaning up spills. Paper towel dispensers are commonly used in toilet facilities shared by many people (such as at schools or shopping malls), as they are often considered more hygienic than hot-air hand dryers or shared cloth towels.

Toilet Paper
Toilet paper (sometimes called toilet/bath/bathroom tissue, or toilet roll) is a tissue paper product primarily used to clean the human anus, anus and surrounding region of Human feces, feces (after defecation), and to clean the external genitalia and perineum, perineal area of urine (after urination). It is commonly supplied as a long strip of perforated paper wrapped around a cylindrical paperboard core, for Toilet paper holder, storage in a dispenser within arm's reach of a toilet. The bundle, or ''roll of toilet paper'', is specifically known as a toilet roll, loo roll, or bog roll (in British English, Britain). There are other uses for toilet paper, as it is a readily available household product. It can be used for blowing the nose or wiping the eyes (or other uses of facial tissue). It can be used to wipe off sweat or absorb it. Some people may use the paper to absorb the bloody discharge that comes out of the vagina during menstruation. Toilet paper can be used in cle ...

Textile
Textile is an Hyponymy and hypernymy, umbrella term that includes various Fiber, fiber-based materials, including fibers, yarns, Staple (textiles)#Filament fiber, filaments, Thread (yarn), threads, and different types of #Fabric, fabric. At first, the word "textiles" only referred to woven fabrics. However, weaving is not the only manufacturing method, and many other methods were later developed to form textile structures based on their intended use. Knitting and Nonwoven, non-woven are other popular types of fabric manufacturing. In the contemporary world, textiles satisfy the material needs for versatile applications, from simple daily clothing to Bulletproof vest, bulletproof jackets, spacesuits, and Medical gown, doctor's gowns. Textiles are divided into two groups: consumer textiles for domestic purposes and technical textiles. In consumer textiles, Aesthetics (textile), aesthetics and Textile performance#Comfort, comfort are the most important factors, while in techn ...

Detergent
A detergent is a surfactant or a mixture of surfactants with Cleanliness, cleansing properties when in Concentration, dilute Solution (chemistry), solutions. There are a large variety of detergents. A common family is the alkylbenzene sulfonates, which are soap-like compounds that are more soluble than soap in hard water, because the polar sulfonate is less likely than the polar carboxylate of soap to bind to calcium and other ions found in hard water. Definitions The word ''detergent'' is derived from the Latin adjective , from the verb , meaning to wipe or polish off. Detergent can be defined as a surfactant or a mixture of surfactants with cleansing properties when in Concentration, dilute Solution (chemistry), solutions. However, conventionally, detergent is used to mean synthetic cleaning compounds as opposed to ''soap'' (a salt of the natural fatty acid), even though soap is also a detergent in the true sense. In domestic contexts, the term ''detergent'' refers to househ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
