Manja (kite)
Fighter kites in Afghanistan, Bangladesh, India, Nepal and Pakistan fly on abrasive string called manja (or manjha). In Brazil, similar string is called "cerol", and in Chile "hilo curado". Kites are typically flown in specific seasons or festivals. All flyers will use coloured manja line, coated with powdered glass, and attempt to cut down opposing kites - which will drift away. Participants or bystanders often run after and try to capture such kites; a practice known as kite running. Names Abrasive cutting line for fighter kites is known under many local names: * ''manjha'' – India, Nepal, Bangladesh and Pakistan. * ''tar'' – Afghanistan * ''hilo de competencia'' – Chile * ''hilo curado'' – Chile * ''dore'' – India and Pakistan * ''manjho'' – Rajasthan, India * ''gelasan'' – Indonesia * ''cerol'' – Brazil Composition Traditional manja is based on fine pure cotton thread coated with a mixture of rice glue, tree gums and similar natural ingredients - and an ab ...

Fighter Kite
Fighter kites are kites used for the sport of kite fighting. Traditionally most are small, unstable single-line flat kites where line tension alone is used for control, at least part of which is manja, typically glass-coated cotton strands, to cut down the line of others. Kite fighting is contested in many countries, but particularly in Afghanistan, Bangladesh, India, Indonesia, Nepal, Pakistan, Vietnam, Korea, Thailand, Chile and Brazil. Materials In most traditional fighter kite manufacture, the skins of kites are made from a lightweight thin paper and the spars are usually made from a lightweight and flexible wood, usually bamboo. In modern American fighters, the kite skins are made from a variety of synthetic materials – mylar, aircraft insulation (orcon or insulfab), nylon, and polyester sheeting. The spine may still be bamboo, but often along with the bow is constructed of fiberglass or carbon fibre. Line Historically, for most Asian type fighters, a thin cotto ...

Kite Running
Kite running is the practice of running after drifting kites in the sky that have been cut loose in kite fighting. Typically the custom is that the person who captures a cut kite can keep it, so the bigger and more expensive looking the kite, the more people can usually be seen running after it to try to capture it. Kite fights Kite fighting is a popular pastime in the Indian subcontinent throughout the year and during kite flying festivals, and also in Afghanistan, Iran, in Chile and Brazil, and many other places throughout the world. In most cases, the fine string that is used to fly these kites is coated with powdered glass and flyers try to cut the string of the other kites. Running When the loser's kite string is cut, the kite drifts free with the wind until it falls to the ground. Kite running is the practice of running after these cut kites to try to capture them when they come down. Typically the custom is that the person who captures a cut kite can keep it. In cities a ...

Zirconia Alumina
Zirconia alumina is commonly used as a sand-blasting medium. It is typically used as an abrasive in casting and foundry processes. Zirconia alumina is a mixture of zirconium dioxide Zirconium dioxide (), sometimes known as zirconia (not to be confused with zircon), is a white crystalline oxide of zirconium. Its most naturally occurring form, with a monoclinic crystalline structure, is the mineral baddeleyite. A dopant stabi ... and aluminium oxide. Zirconia toughened alumina typically consists of alumina with a 10 to 20 percent zirconia concentration, which enhances the toughness of the alumina. To achieve the increase in the composite's strength, a process known as stress induced transformation toughening takes place. Stress induced transformation toughening results in uniform internal strain, which causes the zirconia structure to crack, and the zirconia particles to switch phases. Because of this phase switch, the amount of zirconia particles increases and creates stresses w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synthetic Fibers
Synthetic fibers or synthetic fibres (in British English; see spelling differences) are fibers made by humans through chemical synthesis, as opposed to natural fibers that are directly derived from living organisms, such as plants (like cotton) or fur from animals. They are the result of extensive research by scientists to replicate naturally occurring animal and plant fibers. In general, synthetic fibers are created by extruding fiber-forming materials through spinnerets, forming a fiber. These are called synthetic or artificial fibers. The word polymer comes from a Greek prefix "poly" which means "many" and suffix "mer" which means "single units". (Note: each single unit of a polymer is called a monomer). Early experiments The first fully synthetic fiber was glass. Joseph Swan invented one of the first artificial fibers in the early 1880s; today it would be called semisynthetic in precise usage. His fiber was drawn from a cellulose liquid, formed by chemically modifying ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
