Paintballs
Paintball is an equipment-intensive sport and in order to safely conduct a game, every player requires a paintball marker, marker with propellant to fire the paint, a mask to protect the eyes and face, Paintball equipment#Paintballs, paintballs, and a loader to hold them. To ensure safety off the playing field, a barrel sock or plug for the marker is also compulsory. Depending on type of play, additional equipment can include gloves, a pack designed to comfortably carry pods containing extra paintballs, and a squeegee or swab for cleaning out the barrel in case a paintball breaks. Players may also elect to wear padding or armor in order to reduce the impact of incoming paintballs. Markers A paintball marker is the primary piece of equipment used in paintball to tag an opposing player. An expanding gas (usually carbon dioxide or high-pressure air) forces a paintball through the barrel at a muzzle velocity of approximately . This velocity is sufficient for most paintballs to break ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paintball Marker
A paintball marker, also known as a paintball gun, paint gun, or simply marker, is an air gun used in the shooting sport of paintball, and the main piece of paintball equipment. Paintball markers use compressed gas, such as carbon dioxide (CO2) or compressed air (HPA), to propel dye-filled gel capsules called paintballs through the barrel and quickly strike a target. The term "marker" is derived from its original use as a tool for forestry personnel to mark trees and ranchers to mark wandering cattle. The muzzle velocity of paintball markers is approximately ; most paintball fields restrict speed to 280–300 ft/s, and small indoor fields may further restrict it down to 250 ft/s. While greater muzzle velocity is possible, it has been ruled unsafe for use on most commercial paintball fields. Marker types Paintball markers fall into two main categories in terms of mechanism – mechanical and solenoid driven electropneumatic. Mechanically operated Mechanically operate ...

Paintball
Paintball is a competitive team shooting sport in which players eliminate opponents from play by hitting them with spherical dye-filled gelatin capsules called paintballs that break upon impact. Paintballs are usually shot using low-energy air weapons called paintball markers that are powered by compressed air or carbon dioxide and were originally designed for remotely marking trees and cattle. The game was invented in May 1981 in New Hampshire by Hayes Noel, a Wall Street stock trader, and Charles Gaines, an outdoorsman and writer. A debate arose between them about whether a city-dweller had the instinct to survive in the woods against a man who had spent his youth hunting, fishing, and building cabins. The two men chanced upon an advertisement for a paint gun in a farm catalogue and were inspired to use it to settle their argument with 10 other men all in individual competition, eventually creating the sport of paintball. The sport is played for recreation and is also play ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electropneumatic Paintball Marker
An electropneumatic paintball marker is a paintball marker that uses a pneumatic solenoid to actuate the hammer and/or bolt's movement. History and basic operation The origin of the electropneumatic paintball marker is the subject of a patent dispute, (blocked link) but is generally acknowledged to have happened more or less simultaneously with the introduction of WDP's and PneuVenture's Shoc ...

Capsule (pharmacy)
In the manufacture of pharmaceuticals, encapsulation refers to a range of dosage forms—techniques used to enclose medicines—in a relatively stable shell known as a capsule, allowing them to, for example, be taken orally or be used as suppositories. The two main types of capsules are: * Hard-shelled capsules, which contain dry, powdered ingredients or miniature pellets made by ''e.g.'' processes of extrusion or spheronization. These are made in two halves: a smaller-diameter “body” that is filled and then sealed using a larger-diameter “cap”. * Soft-shelled capsules, primarily used for oils and for active ingredients that are dissolved or suspended in oil. Both of these classes of capsules are made from aqueous solutions of gelling agents, such as animal protein (mainly gelatin) or plant polysaccharides or their derivatives (such as carrageenans and modified forms of starch and cellulose). Other ingredients can be added to the gelling agent solution including plast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gelatin
Gelatin or gelatine (from la, gelatus meaning "stiff" or "frozen") is a translucent, colorless, flavorless food ingredient, commonly derived from collagen taken from animal body parts. It is brittle when dry and rubbery when moist. It may also be referred to as hydrolyzed collagen, collagen hydrolysate, gelatine hydrolysate, hydrolyzed gelatine, and collagen peptides after it has undergone hydrolysis. It is commonly used as a gelling agent in food, beverages, medications, drug or vitamin capsules, photographic films, papers, and cosmetics. Substances containing gelatin or functioning in a similar way are called gelatinous substances. Gelatin is an irreversibly hydrolyzed form of collagen, wherein the hydrolysis reduces protein fibrils into smaller peptides; depending on the physical and chemical methods of denaturation, the molecular weight of the peptides falls within a broad range. Gelatin is present in gelatin desserts, most gummy candy and marshmallows, ice creams, dips ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Fiber
Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers (Commonwealth English), carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic (CFRP, CRP, CFRTP), also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications. The binding polymer is often a thermoset resin such as epoxy, but other thermoset or thermoplastic polymers, such as polyester, vinyl ester, or nylon, are sometimes used. The properties of the final CFRP product can be affected by the type of additives introduced to the binding matrix (resin). The most common additive is silica, but other addi ...

Polycarbonate
Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, molded, and thermoformed. Because of these properties, polycarbonates find many applications. Polycarbonates do not have a unique resin identification code (RIC) and are identified as "Other", 7 on the RIC list. Products made from polycarbonate can contain the precursor monomer bisphenol A (BPA). Structure Carbonate esters have planar OC(OC)2 cores, which confers rigidity. The unique O=C bond is short (1.173 Å in the depicted example), while the C-O bonds are more ether-like (the bond distances of 1.326 Å for the example depicted). Polycarbonates received their name because they are polymers containing carbonate groups (−O−(C=O)−O−). A balance of useful features, including temperature resistance, impact resistance and o ...

Tippmann C-3
The Tippmann C-3 was the first propane powered paintball marker. It operates on a unique system Tippmann calls 'Propane Enhanced Performance'. The name 'C-3' may refer to the chemical formula of propane, C3H8. Operation While traditional Paintball markers rely upon the expansion of an inert compressed gas (namely or air) for Paintball propulsion, the C-3 utilises the energy released in propane combustion. This is a simplified explanation of the C-3's firing system: The C-3 operates on a closed bolt system. As the pump is pulled back by the shooter, the bolt moves back to allow one paintball to fall into the breech. As the shooter returns the pump to the forward position, completing the pumpstroke, propane is drawn into the combustion chamber. The bolt also moves forward, sealing the breech, and bringing the paintball into the firing position. After the pump stroke, the shooter pulls the trigger, causing a spark and igniting the propane. The resulting expansion of gases for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
