How is the original jade stone fake? Let you avoid being cheated!
The junk market in the jade market is no longer a new thing, even in the relatively safe field of rough stones, there are also fraud. There are five common falsification techniques. Transfer the flowers: Cut the jade on the poor texture and transplant the jade with the size of the incision, the texture is fine, and the color is beautiful. The local good quality is used to cover the overall bad quality. In the identification, it is necessary to pay attention to the sand in the lower part of the incision and the sand on the mother. The lower part of the incision is generally loose sand, which cannot be granulated, and the sand of the mother is mostly granular. If the whole is different from the sand in the lower part of the incision, then pay attention. Escape from the dead: A good-looking gambling stone, unsatisfactory after unraveling, and then join it to restore its original appearance. The sand at the interface is generally finer than other places and is not granulated. At the time of identification, if the tight sand is a straight line, pay attention. However, when it comes to rust skin, it is generally difficult to identify. Fairy scattered flowers: This refers to the selection of a good place, but no loose flower performance on the original stone, choose the location, sprinkle glue on it, and then spread the polished jade powder on the surface, repaired and buried in the soil for dozens of days Just fine. Opening the window to explore the moon: In the case that the internal situation of the original stone is unknown, in order to find out the internal situation, first open a small hole to find out the inside story. If it is not ideal, then cover the small hole, like this method, it is generally difficult to identify . Fish head mixed beads: select a good part on the original stone, dig a small groove, then put green glass or green toothpaste, and then carefully trimmed the fish. However, most of these things have bubbles in them and the colors are the same. You can identify the true and false by comparing the sand on the edge of the insert with the sand.
Cold Resistant Hydraulic Accumulator Bladder.
The standard Bladder Accumulator consists of a [closed" rubber bladder inside a forged steel shell. A mechanically actuated valve closes when the fluid has been expelled, blocking off the fluid port, thereby enclosing the bladder within the shell. Where high discharge rates are required, a high flow model is available.Applications with corrosive environments may require shells furnished with an internal and/or external coating or manufactured from stainless steel.

When the pressure level of a system permits, a Low Pressure Accumulator may be used. It is similar to a standard bladder accumulator, except that the poppet valve is replaced by a perforated plate covering the fluid port, and the shell may be of welded construction.
