È stato aggiornato il profilo di An earring is a piece of jewelry attached to the ear via a piercing in the earlobe or another external part of the ear (except in the case of clip earrings, which clip onto the lobe). Earrings have been worn by people in different civilizations and historic periods, often with cultural significance. Locations for piercings other than the earlobe include the rook, tragus, and across the helix (see image at right). The simple term "ear piercing" usually refers to an earlobe piercing, whereas piercings in the upper part of the external ear are often referred to as "cartilage piercings". Cartilage piercings are more complex to perform than earlobe piercings and take longer to heal. Earring components may be made of any number of materials, including metal, plastic, glass, precious stone, beads, wood, bone, and other materials. Designs range from small loops and studs to large plates and dangling items. The size is ultimately limited by the physical capacity of the earlobe to hold the earring without tearing. However, heavy earrings worn over extended periods of time may lead to stretching of the earlobe and the piercing. http://www.asejewel.com/ring/ 3 anni, 2 mesi fa

“Nowadays, PPR is the most commonly used material for pipes and fittings. PPR is a random copolymer polypropylene. In winter, the flexibility of PPR water pipes will decrease, while the rigidity will increase and flatten. If the pipe is impacted by an external force, the surface of the pipe will crack more seriously.
Therefore, PPR Pipe…[Leggi tutto]

“Metal honeycomb substrates used in catalytic converters are made from extremely thin metal foil, typically with a thickness of just 0.05mm. By comparison the walls of a ceramic substrate may be four times thicker. For this reason, metal substrates offer less resistance to gas flow and therefore can accommodate a given flow rate with a lower…[Leggi tutto]

È stato aggiornato il profilo di Solder is a fusible metal alloy used to create a permanent bond between metal workpieces. Solder is melted in order to wet the parts of the joint, where it adheres to and connects the pieces after cooling. Metals or alloys suitable for use as solder should have a lower melting point than the pieces to be joined. The solder should also be resistant to oxidative and corrosive effects that would degrade the joint over time. Solder used in making electrical connections also needs to have favorable electrical characteristics. Soft solder typically has a melting point range of 90 to 450 °C (190 to 840 °F; 360 to 720 K), and is commonly used in electronics, plumbing, and sheet metal work. Alloys that melt between 180 and 190 °C (360 and 370 °F; 450 and 460 K) are the most commonly used. Soldering performed using alloys with a melting point above 450 °C (840 °F; 720 K) is called "hard soldering", "silver soldering", or brazing. In specific proportions, some alloys are eutectic — that is, the alloy's melting point is the lowest possible for a mixture of those components, and coincides with the freezing point. Non-eutectic alloys can have markedly different solidus and liquidus temperatures, as they have distinct liquid and solid transitions. Non-eutectic mixtures often exist as a paste of solid particles in a melted matrix of the lower-melting phase as they approach high enough temperatures. In electrical work, if the joint is disturbed while in this "pasty" state before it fully solidifies, a poor electrical connection may result; use of eutectic solder reduces this problem. The pasty state of a non-eutectic solder can be exploited in plumbing, as it allows molding of the solder during cooling, e.g. for ensuring watertight joint of pipes, resulting in a so-called "wiped joint". http://www.hcdurostone.com/solder-pallet-material/ 3 anni, 3 mesi fa
