Floor Cleaning
Floor cleaning is a major occupation throughout the world. The main job of most cleaners is to clean floors. Reasons for cleaning floors The principal reasons for floor cleaning are: * To prevent injuries due to tripping or slipping. Injuries due to slips and trips on level floors are a major cause of accidental injury or death. Bad practice in floor cleaning is itself a major cause of accidents. * To beautify the floor. * To remove stains, dirt, litter and obstructions. * To remove grit and sand which scratch and wear down the surface. * To remove allergens, in particular dust. * To prevent wear to the surface (e.g. by using a floor wax or protective sealant). * To make the environment sanitary (e.g. in kitchens). * To reduce ingestion/inhalation rates of microplastics. * To maintain an optimum traction (e.g. for dance floors). *Reduce workload inbetween shifts (e.g. dedicated cleaning crew). Methods of floor cleaning The treatment needed for different types of floors i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Performance Surface
A performance surface is a flooring suitable for dance or sport. Performance surfaces are normally laid on top of, or are part of, a sprung floor to produce a complete dance floor or sports floor. Dance performance surfaces made of sheet vinyl are also called dance floors and marley floors. They are called marley-type floors from a very popular reversible vinyl flooring manufactured for years until about 1978 by Marley Floors Ltd. Theatres often have a number of roll-out floors with different characteristics to satisfy the requirements of different forms of dance. This article deals mainly with the customization of a floor for different activities by the use of different surfaces. The sprung floor article deals with the basic requirements and construction of floors to make them suitable for dance and indoor sports. Requirements The sprung floor article outlines some of the different standards with regards to the performance surface of a sports floor. Below are some of the ke ...

Formulation
Formulation is a term used in various senses in various applications, both the material and the abstract or formal. Its fundamental meaning is the putting together of components in appropriate relationships or structures, according to a formula. Etymologically ''formula'' is the diminutive of the Latin ''forma'', meaning shape. In that sense a ''formulation'' is created according to the standard for the product. Abstract applications Disciplines in which one might use the word ''formulation'' in the abstract sense include logic, mathematics, linguistics, legal theory, and computer science. For details, see the related articles. Material applications In more material senses the concept of ''formulation'' appears in the physical sciences, such as physics, chemistry, and biology. It also is ubiquitous in industry, engineering and medicine, especially pharmaceutics. Pharmacy In pharmacy, a formulation is a mixture or a structure such as a capsule, tablet, or an emulsion, ...

Floor Scrubber
A floor scrubber is a floor cleaning device. It can be a simple tool such as a floor mop or floor brush, or in the form of a walk-behind or a ride-on machine to clean larger areas by injecting water with cleaning solution, scrubbing, and lifting the residue off the floor. With advancements in robotics, autonomous floor-scrubbing robots are available as well. Automatic floor scrubbers Automatic floor scrubbers, also known as auto scrubbers, are a type of floor cleaning machine that are used to scrub a floor clean of light debris, dust, oil, grease or floor marks. These machines have either a rotary (disk) or cylindrical scrubbing head and an automated system for dispensing cleaning solution and then vacuuming it up. So, in one pass over the floor, a user can dispense a cleaning agent, scrub it into the floor, then vacuum it all up with an autoscrubber squeegee attachment at the back of the machine. Auto scrubbers have a separate dispensing (solution) tank and collection (recove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vinyl Composition Tile
Vinyl composition tile (VCT) is a finished flooring material used primarily in commercial and institutional applications. Modern vinyl floor tiles and sheet flooring and versions of those products sold since the early 1980s are composed of colored polyvinyl chloride (PVC) chips formed into solid sheets of varying thicknesses ( is most common) by heat and pressure. Floor tiles are cut into modular shapes such squares or rectangles. In installation the floor tiles or sheet flooring are applied to a smooth, leveled sub-floor using a specially formulated vinyl adhesive or tile mastic that remains pliable. In commercial applications some tiles are typically waxed and buffed using special materials and equipment. Modern vinyl floor tile is frequently chosen for high-traffic areas because of its low cost, durability, and ease of maintenance. Vinyl tiles have high resilience to abrasion and impact damage and can be repeatedly refinished with chemical strippers and mechanical buffin ...

Porcelain
Porcelain () is a ceramic material made by heating substances, generally including materials such as kaolinite, in a kiln to temperatures between . The strength and translucence of porcelain, relative to other types of pottery, arises mainly from vitrification and formation of the mineral mullite within the body at these high temperatures. Though definitions vary, porcelain can be divided into three main categories: hard-paste, soft-paste, and bone china. The category that an object belongs to depends on the composition of the paste used to make the body of the porcelain object and the firing conditions. Porcelain slowly evolved in China and was finally achieved (depending on the definition used) at some point about 2,000 to 1,200 years ago; it slowly spread to other East Asian countries, then to Europe, and eventually to the rest of the world. Its manufacturing process is more demanding than that for earthenware and stoneware, the two other main types of pottery, and it ...

Ceramic
A ceramic is any of the various hard, brittle, heat-resistant and corrosion-resistant materials made by shaping and then firing an inorganic, nonmetallic material, such as clay, at a high temperature. Common examples are earthenware, porcelain, and brick. The earliest ceramics made by humans were pottery objects (''pots,'' ''vessels or vases'') or figurines made from clay, either by itself or mixed with other materials like silica, hardened and sintered in fire. Later, ceramics were glazed and fired to create smooth, colored surfaces, decreasing porosity through the use of glassy, amorphous ceramic coatings on top of the crystalline ceramic substrates. Ceramics now include domestic, industrial and building products, as well as a wide range of materials developed for use in advanced ceramic engineering, such as in semiconductors. The word "'' ceramic''" comes from the Greek word (), "of pottery" or "for pottery", from (), "potter's clay, tile, pottery". The earliest kno ...

Travertine
Travertine ( ) is a form of terrestrial limestone deposited around mineral springs, especially hot springs. It often has a fibrous or concentric appearance and exists in white, tan, cream-colored, and even rusty varieties. It is formed by a process of rapid precipitation of calcium carbonate, often at the mouth of a hot spring or in a limestone cave. In the latter, it can form stalactites, stalagmites, and other speleothems. It is frequently used in Italy and elsewhere as a building material. Similar (but softer and extremely porous) deposits formed from ambient-temperature water are known as tufa. Definition Travertine is a sedimentary rock formed by the chemical precipitation of calcium carbonate minerals from fresh water, typically in springs, rivers, and lakes; that is, from surface and ground waters. In the broadest sense, travertine includes deposits in both hot and cold springs, including the porous, spongy rock known as tufa, and also the cave features known as speleot ...

Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Marble
Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or Dolomite (mineral), dolomite. Marble is typically not Foliation (geology), foliated (layered), although there are exceptions. In geology, the term ''marble'' refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is commonly used for Marble sculpture, sculpture and as a building material. Etymology The word "marble" derives from the Ancient Greek (), from (), "crystalline rock, shining stone", perhaps from the verb (), "to flash, sparkle, gleam"; Robert S. P. Beekes, R. S. P. Beekes has suggested that a "Pre-Greek origin is probable". This Stem (linguistics), stem is also the ancestor of the English language, English word "marmoreal," meaning "marble-like." While the English term "marble" resembles the French language, French , most other European languages (with words like "marmoreal") more closely resemb ...

Carpet
A carpet is a textile floor covering typically consisting of an upper layer of pile attached to a backing. The pile was traditionally made from wool, but since the 20th century synthetic fibers such as polypropylene, nylon, or polyester have often been used, as these fibers are less expensive than wool. The pile usually consists of twisted tufts that are typically heat-treated to maintain their structure. The term ''carpet'' is often used in a similar context to the term ''rug'', but rugs are typically considered to be smaller than a room and not attached to the floor. Carpets are used for a variety of purposes, including insulating a person's feet from a cold tile or concrete floor, making a room more comfortable as a place to sit on the floor (e.g., when playing with children or as a prayer rug), reducing sound from walking (particularly in apartment buildings), and adding decoration or color to a room. Carpets can be made in any color by using differently dyed fibers. C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sweepers
A street sweeper or street cleaner may refer to a person's occupation or to a machine that cleans streets. Street sweepers have been employed in cities as "sanitation workers" since sanitation and waste removal became a priority. A street-sweeping person would use a broom and shovel to clean off litter, animal waste and filth that accumulated on streets. Later, water hoses were used to wash the streets. Machines were created in the 19th century to do the job more efficiently. Today, modern street sweepers are mounted on truck bodies and can vacuum debris that accumulates in streets. Modern sweepers Street sweepers are capable of collecting small particles of debris. Many street sweepers produced today are PM10 and PM2.5 certified, meaning that they are capable of collecting and holding particulate matter sized less than 10μm and even down to 2.5μm. Despite advancements in street sweeping technology, the mechanical broom type street sweeper accounts for approxima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
