Jadeite is a treasure of jade and is a beautiful and magical product of nature. It can not only be decorated, but also has ornamental and collectible values. Jadeite is a rock dominated by soda-alumina, which can be divided due to the different degrees of fineness and color of the rock. Many varieties, usually divided into delicate old jade or old pit; coarsely divided into new species or new pits, small particles mottled visible; between the above two varieties, if there are particles, Divided into new and old species. "Plant" is one of the keys to measuring the quality of jadeite. It refers to the thickness and transparency of jade. The old-fashioned color is better after processing, and then look at the color under the good conditions. This is what the jargon says is "a layman's color, and the insider looks at it."
Among the old jadeites, there is a kind of glass that has no color but is psychic and versatile. The jargon is called a kind of colorless. Glass type, as the name suggests, is as transparent as glass, with very fine quality and dense crystalline particles. It is one of the best in jade. Colorless glass species does not involve the determination of color, and the evaluation value is relatively easy. For those who just started collecting jade, it is easier to master. In the past few years, a large number of primary collectors have entered the jadeite category, making colorless. Glass varieties have become the fastest-growing varieties in recent years.
Glass type jade has good transparency (that is, transparency refers to the ability of an object to transmit visible light), and particles, impurities, and splitting are easily seen clearly. Because jadeite is not a diamond, as a single crystal mineral, diamonds are not allowed to have impurities seen by the naked eye; jadeite is a combination of various minerals, and there must be various structural and crystal changes. Most jadeites are opaque and can't see the inside. The ice and glass are fine and clean. You can see the structure inside. If you don't know how to do it, you will think that this jade is not perfect. In fact, it is a flaw that reflects the jade texture. Excellent. A high quality jade has a bit of impurities and is generally not a big problem. In fact, the top jadeite is not without any embarrassment. Looking at a jade, the focus is not on picking, but on a few big aspects - good, good color, good shape. Just because there is a little impurity, it is a mistake to miss the good emerald. The transparency of jadeite varies greatly. The crystal clear jade is called the head of the water, otherwise it is called the dry, and the transparency is related to the germplasm. As the saying goes, "the seed is good and the ugly."
The glass species of jade comes from the old pit jade stone. The old pit cui material is very rare in the production area, accounting for less than 1% of the output of the jade raw materials in the mine; the gambling stone is the gambling of jadeite and the emerald green, and the old pit jade stone often has a husk, its original stone. The gambling is also relatively large; in recent years, such raw stones in the raw material market, whether in the country of origin of Myanmar or in China, most of them need to be auctioned, so the old pit jade stone is relatively rare.
In the colorless type of jade, the glass species of jadeite should be in the position of the pyramid spire, and the ethereal and transparent, often weaken the carving skills. On a large area of ​​clear surface, after a high-quality polishing, there will be a group of floating light, which is often said to "starting Ying". In recent years, the value of glass jade in the jewelry market has skyrocketed and is unstoppable. Because it is not as colorful as a green jade, pure water is more like the love of young people, there is a low-key luxury.
Buffer rings (HBY, HBTS) are mainly installed on the pressure side of the piston rod seal. The buffer rings literally help improve the durability of the piston rod seal and play three roles:
Buffer the impact pressure generated by the piston rod side of the hydraulic cylinder, and relieve the back pressure
Prevent the oil temperature from being directly overheated to the seal, which will lead to the deterioration of the seal, and play the role of buffering and slightly cooling.
Reduce the friction resistance of the piston rod seal and the sliding and heating of the seal during the movement of the oil cylinder.
