Duct Tape
Duct tape or duck tape is cloth- or scrim-backed pressure-sensitive tape, often coated with polyethylene. A variety of constructions exist using different backings and adhesives, and the term "duct tape" has been genericized to refer to all of them. A variation is heat-resistant foil tape useful for sealing heating and cooling ducts, produced because standard duct tape fails when used on heating ducts. Duct tape is generally silvery gray in color, but also available in other colors and printed designs, from whimsical yellow ducks to practical camouflage patterns. It is often confused with gaffer tape which is designed to be non-reflective and cleanly removed, unlike duct tape. During World War II, Revolite (then a division of Johnson & Johnson) developed an adhesive tape made from a rubber-based adhesive applied to a durable duck cloth backing. This tape resisted water and was used to seal some ammunition cases during that period. "Duck tape" is recorded in the ''Oxford ...

Cotton Duck
Cotton duck (from , meaning "cloth"), also simply duck, sometimes duck cloth or duck canvas, is a heavy, plain weave, plain woven cotton Textile, fabric. Duck canvas is more tightly woven than canvas, plain canvas. There is also linen duck, which is less often used. Cotton duck is used in a wide range of applications, from sneaker (footwear), sneakers to painting canvases to tents to sandbags. Historically, white untwilled cotton or linen fabric uniforms of this name were worn by British and French soldiers serving in the tropics. Duck fabric is woven with two yarns together in the warp (weaving), warp and a single yarn in the weft. By treating with wax, duck fabric can be made waterproof (see waxed cotton). Cotton duck strips were the origin of duck tape, recorded in the Oxford English Dictionary as having been in use since 1899 (see duct tape). Classification Duck is classified according to weight in a numerical system, with grade 1 the heaviest and grade 12 the lighte ...

Masking Tape
Masking tape, also known as painter's tape, is a type of pressure-sensitive tape made of a thin and easy-to-tear paper, and an easily released pressure-sensitive adhesive. It is available in a variety of widths. It is used mainly in painting, to Masking (in art), mask off areas that should not be painted. Some inexpensive masking tapes are suited for general use in homes and offices. Others are designed for professional house painters. Masking tapes for automotive or aircraft use have special characteristics for these demanding applications. History Masking tape was created in 1925 by 3M employee Richard Gurley Drew. Drew observed automobile, autobody workers growing frustrated when they removed butcher paper they had taped to cars they were painting. The strong adhesive on the tape peeled off some of the paint they had just applied. Touching up the damaged areas increased their costs. Drew realized the need for tape with a gentler adhesive.

Richard Gurley Drew
Richard Gurley Drew (June 22, 1899 – December 14, 1980) was an American inventor who worked for Johnson and Johnson, Permacel Co., and 3M in St. Paul, Minnesota, where he invented masking tape and cellophane tape. Biography When Drew joined 3M in St. Paul, Minnesota in 1921, it was a modest manufacturer of sandpaper. While testing their new Wetordry sandpaper at auto shops, Drew was intrigued to learn that the two-tone auto paintjobs so popular in the Roaring Twenties were difficult to manage at the border between the two colors. In response, after two years of work in 3M's labs, Drew invented the first masking tape (1925), a two-inch-wide tan paper strip backed with a light, pressure-sensitive adhesive. The first tape had adhesive along its edges but not in the middle. In its first trial run, it fell off the car and the frustrated auto painter growled at Drew, "take this tape back to those Scotch bosses of yours and tell them to put more adhesive on it!" (By "Scotch", he mean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inner Tube
An inner tube is an inflatable torus that forms the interior of some pneumatic tires. The tube is inflated through a valve stem and fits inside the tire casing. The inflated inner tube provides structural support and suspension, while the outer tire offers grip and protects the more fragile tube. Use Nowadays, most bicycle tires use inner tubes. They are also used in items such as dolly carts, wheelbarrows, and many motorcycles. In the past, car tires used inner tubes, but most cars now use tubeless tires that hold air without an inner tube. Tubeless tires offer advantages, as they can operate at both low and high pressures without the risk of pinching or bursting, unlike tube tires. Large inner tubes are used for various recreational activities, such as flotation devices in tubing. History Inner tubes were invented in the 1800s for use with pneumatic tires, as standard wheels at the time were not air-filled, making them uncomfortable to ride on. Over the years, inner ...

Rosin
Rosin (), also known as colophony or Greek pitch (), is a resinous material obtained from pine trees and other plants, mostly conifers. The primary components of rosin are diterpenoids, i.e., C20 carboxylic acids. Rosin consists mainly of resin acids, especially abietic acid. Rosin often appears as a semi-transparent, brittle substance that ranges in color from yellow to black and melts at stove-top temperatures. In addition to industrial applications such as in varnishes, adhesives, and sealing wax, rosin is used with string instruments on the bow hair to enhance its ability to grip and sound the strings, and it provides grip in various sports and activities. Rosin also serves as an ingredient in medicinal and pharmaceutical formulations and can cause contact dermatitis or occupational asthma in sensitive individuals. It is an FDA approved food additive. The name "colophony" originates from , Latin for "resin from Colophon" (), an ancient Ionic city. Properties R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electrical Tape
Electrical tape (or insulating tape) is a type of pressure-sensitive tape used to insulate electrical wires and other materials that conduct electricity. It can be made of many plastics but PVC (polyvinyl chloride, "vinyl") is the most popular, as it stretches well and gives effective and long-lasting insulation. Electrical tape for class H insulation is made of fiberglass cloth. Varieties A wide variety of electrical tapes are available, some for highly specialized purposes. "The primary tapes used in electrical applications are vinyl, rubber, mastic, and varnished cambric."Bob Goodman and Rodney G. Brown (3M).Electrical Taping Skills: A Lost Art?, ''EC&M'', p.2. Electricians may use various colors of tape to insulate wire and to indicate the voltage level and phase of the wire (colored tape sometimes is called "phasing tape"). When wires are phased, a ring of tape is placed on each end near the termination so that the purpose of the wire is obvious. The following tabl ...

Friction Tape
Friction tape is a type of woven Textile, cloth adhesive tape, historically made of cotton, impregnated with a rubber-based adhesive. Sticky on both sides, it is mainly used by electricians to Insulator (electricity), insulate splices in electric wires and cables. The rubber-based adhesive provides a degree of protection from liquids and corrosion, while the cloth mesh protects against punctures and abrasion. It has been supplanted by Polyvinyl chloride, PVC-based electrical tape except commonly used for over wrapping. Other uses Friction tape is commonly used to improve the grip on various sporting implements, including tennis racquets, baseball bats, and hockey sticks. It is also used similarly on the handlebars of bicycles, dirt bikes, lawnmowers, and other small machines that require gripping or steering.

Zinc Oxide
Zinc oxide is an inorganic compound with the Chemical formula, formula . It is a white powder which is insoluble in water. ZnO is used as an additive in numerous materials and products including cosmetics, Zinc metabolism, food supplements, rubbers, plastics, ceramics, glass, cement, lubricants, paints, sunscreens, ointments, adhesives, sealants, pigments, foods, batteries, ferrites, fire retardants, semi conductors, and first-aid tapes. Although it occurs naturally as the mineral zincite, most zinc oxide is produced synthetically. History Early humans probably used zinc compounds in processed and unprocessed forms, as paint or medicinal ointment; however, their composition is uncertain. The use of ''pushpanjan'', probably zinc oxide, as a salve for eyes and open wounds is mentioned in the Indian medical text the Charaka Samhita, thought to date from 500 BC or before. Zinc oxide ointment is also mentioned by the Greek physician Dioscorides (1st century AD). Galen suggested treatin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adhesive Tape
Adhesive tape is one of many varieties of backing materials coated with an adhesive. Several types of adhesives can be used. Types Pressure-sensitive tape Pressure-sensitive tape, PSA tape, self-stick tape or sticky tape consists of a pressure sensitive adhesive coated onto a backing material such as paper, plastic film, cloth, or metal foil. It is sticky (tacky) without any heat or solvent for activation and adheres to surfaces with light pressure. Typical adhesives are polymers such as acrylates, natural rubber, natural, and synthetic rubber. These tapes usually require a release agent on their backing or a release liner to cover the adhesive. Sometimes, the term "adhesive tape" is used for these tapes. Water-activated tape Water-activated tape, gummed paper tape or gummed tape is starch- or sometimes animal glue-based adhesive on a paper backing which becomes sticky when moistened. A specific type of gummed tape is called reinforced gummed tape (RGT). The backing o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Venetian Blinds
A window blind is a type of window covering. There are many different kinds of window blinds which use a variety of control systems. A typical window blind is made up of several long horizontal or vertical slats of various types of hard material, including wood, plastic or metal which are held together by cords that run through the blind slats. Vertical blinds run along a track system which can tilt open and closed and move side-to-side. Window blinds can be manoeuvred with either a manual or remote control by rotating them from an open position, with slats spaced out, to a closed position where slats overlap and block out most of the light. There are also several types of window coverings, called shades, that use a single piece of soft material instead of slats. The term window blinds can also be used to describe window coverings more broadly. In this context window blinds include almost every type of window covering, whether it is a hard or soft material; i.e. shutters, rol ...
