Modern necklaces, mostly as an accessory, did not seem to be the case before the distant. In the distant Paleolithic era, the cavemen connected the perforations of small stone beads, small shuribs, animal teeth, and animal bones to their chests. Many people thought that this was the predecessor of the necklace. According to research experts, the primitive people’s behavior of wearing necklaces is not for beauty, but for counting and memorizing. If you want to say other things, it is only for the companion who is trying to hunt. There are many animals. This is a utilitarian behavior, and the source of the jade necklace, which is gradually developed from utilitarianism to aesthetics, has gradually formed through the passage of the age.

After the Neolithic Age, it was discovered from the excavated tombs that these string ornaments had many artificial traces in the choice of particle size and materials. Some unearthed relics also found jade ornaments that were passed through. Formed by certain craftsmanship, this may be the earliest craftsmanship of man making decorations, which is the initial stage of development of necklaces. After entering the class society, the poor and the nobility began to wear necklaces, but the necklaces they wear have great differences in materials. Most of the necklaces worn by the aristocratic class are mainly jade, while the civilians dress themselves with snails, shells and shells.

In addition to wearing necklaces, ancient women also prevailed in sputum, and sputum can also be called 璎珞, which was originally decorated between the necks of Buddha statues. After Buddhism was passed down from India to China, the shackles on the Buddha statue were also emulated. Buddhists recited the beads used to count the Buddhist scriptures, and also passed along with Buddhism to China. Since most of the folk women believe in Buddhist chanting, the wearing of the beads is quickly becoming popular. Chaozhu is a kind of ornament introduced by the Jurchens of the Qing Dynasty. It is made of coral, crystal, jade, amber, turquoise, agate and other materials. The necklaces of the Republic of China, influenced by Western culture and customs, have undergone great changes in the style of the necklace. At that time, the most important thing was to put a pendant on the necklace. The common pendant style is a chicken heart type or a chicken heart box. The inside of the small box can hide photos and engrave names, which means heart and soul. Nowadays, jade necklaces are gradually gaining popularity. In addition to wearing gold and silver necklaces, the emerald necklaces seem to be more temperamental.

Nowadays, with the advancement of the times and the high development of technology and crafts, the jade necklace has a wider world. The variety of jade necklaces is more and more abundant, and the production process and aesthetic effects are getting better and better. I believe that there will be a big breakthrough in the future jade necklace.

Silicone Shock Absorber

Rubber Damper, also known as Shock Absorber, Isolator, and NBR grommet, NBR is a unsaturated rubber copolymer with polar unsaturated carbon chains, which is copolymerized by propenenitrile and butadiene, according to propenenitrile content from low to high, the higher the resistance to oils but the lower the resistance to cold. Oil resistance is the greatest advantage of NBR elastomer so it has excellent resistance to petroleum base oils and non-polar solvents but poor resistance to polar oils and polar solvents.
Nitrile rubber (NBR, Buna-N) grommet provides excellent resistance to petroleum oils as well as mineral and vegetable oil. Nitrile rubber also offers strong resistance to heat aging - often a key advantage over natural rubber.
