Application of titanium chain in jewelry
Starting with the line to make the chain, about the beginning of the Egyptian and Mesopotamian civilization about 2,500 years ago, there was a technique of weaving chains into gold chains. At the beginning, it was connected in a ring shape, starting with the simplest form, slowly increasing the fineness, twisting, etc. of the production, and thinking about how to make a new type of chain. In the medieval European royal palace, the portraits of the wealthy merchants must be painted with a large number of gold chains hanging on their bodies. In Japan, the tassels on the ancient armor and the spreaders of the knives are used in chains.
According to its use, the chain can be divided into: industrial applications, such as heavy objects such as anchors for hoisting ships and transmission parts, mainly steel materials; people's livelihood households, such as the slings of mercury lamps, plugs of bathtubs, etc., so that the value of iron, Brass and aluminum are the main materials; jewelry applications, the longest history, the most diverse types, divided into two kinds of hand-made and automatic mechanical, the use of materials from gold, platinum and silver and other precious metals to brass, red Alloys such as copper, aluminum, silver, and stainless steel are used in necklaces, bracelets, pendants, pendants, and brooches.
The earliest notice of making titanium was about around 1980. At that time, European countries began to implement countermeasures against the human body for metal allergy, and began to limit the total content of nickel metal in the jewelry. Brass and copper jewelry because of the need to use nickel metal to increase the gloss of its jewelry, so there is no doubt that its nickel metal content must exceed. Not only nickel metal, but also allergic to precious metals (gold, platinum) is also widely known. For this reason, it is inevitable that the titanium metal suitable for the human body will be explored as a material for jewelry. But the actual use is stagnant. The biggest reason is that the largest customer base of jewelry is women, and its interest in titanium is not enough. On the other hand, for the actual product planner, the titanium chain and peripheral parts are extremely rare compared with other metal materials, and the processing method and surface treatment method are completely different from the existing metals, thus causing titanium metal. The use of stagnant.
Titanium itself does not have the same price as gold and white. However, the functional properties of titanium (physical suitability, high food resistance, shape memory characteristics, light weight) and processing difficulties make "sparseness" and "persistence" in the individual's performance in the material for jewelry to have a specific distinction. possibility. Nowadays, titanium metal is mainly used in the health industry, which is a topic of allergy to metals. It is often used in the magnetic gas collar of one of the magnetic gas therapy devices. Its food resistance is superior, and titanium is used which does not cause metal allergy. Chains and parts have also increased.
Slim Rotary Damper mainly used for small diameter, long height space. Shaft Damper is used to dampen drives, control speed, and many other applications. Shaft damper are widely used in invisible screens. Shaft damper can make the movement of structures soft, quiet and safe to mitigate the impact, avoid the damage, increase the mechanical life, reduce noise, and improve product quality.
