Crystal has always been a symbol of romance. Crystal lamps have been adhering to this characteristic feature and are increasingly used by many merchants in hotels, hotel lobbies or banquet halls to create an atmosphere. Therefore, the regular cleaning and maintenance of the crystal lamp not only makes the effect better, but also prolongs the service life of the crystal lamp.

Cleaning the crystal lamp 1. Select the appropriate crystal lamp cleaner for spraying. You can choose to purchase professional crystal lamp cleaners. After spraying a proper amount of cleansing agent on the crystal lamps, the floating dust of the crystal ball or the wafer will be taken away as the liquid evaporates;

2. Remove the crystal lamp for thorough cleaning. To avoid fingerprints on crystal lamps, wear white cotton gloves when cleaning crystal lamps. Remove the crystals one by one, dip them into a container containing kerosene, and then gently wipe the crystal appearance with a toothbrush. After the dust of the appearance is slowly softened, wash the crystal blocks with detergent powder. In addition, according to the quality of the detailed crystal lamps, the treatment is treated differently. Some of them only need to use the anti-static dry cloth to wipe off the dust of the crystal lamps.

Crystal lamp maintenance

1. Maintain the balance of the lamp body. If you want to remove all the bead strings, the large lamps should pay attention to the balance of the lamp body when the beads are removed. Do not remove the other side and then remove the other side to cause the lamp body to tilt, resulting in deformation of the lamp body or frame; Disassembled.

2. Wipe the bracket accessories to avoid letting the liquid touch the crystal lamp. When wiping the brackets and accessories, do not touch the water with a soft cloth, especially alcohol, so as not to damage the protective film outside the plating layer and affect the surface gloss effect of the lamp holder.

3. Avoid too much effort when installing. The bulb should also be removed and wiped clean before being installed; the bulb should be moderate when it is screwed in. Too loose will cause poor contact, too tight may ruin the bulb.

4. Replace the accessories at the right time. It is found that the beaded connection buckle is rusty and discolored, and it is not beautiful. The second is easy to be brittle. It is best to change it by the way; if the bead string is found to be missing, it should be filled in time.

Duplex Stainless Steel Overview

Duplex Stainless Steels, also referred to as austenitic-ferritic stainless steels, are a family of grades with about equal proportions of ferrite and austenite. These steels have a duplex microstructure which contributes to their high strength and high resistance to stress corrosion cracking. Due to their high content of chromium, nitrogen and molybdenum, duplex steels offer good resistance to local and uniform corrosion. Duplex stainless steels have good weldability.

Today, modern duplex stainless steels can be divided into three groups:
Lean Duplex such as LDX2101
Standard Duplex such as 2205, the work-horse grade accounting for more than 80% of duplex usage
Super Duplex such as Ferralium 255 and Zeron 100 and LDX2507

Of the duplex grades, duplex 2205 is the most widely used. However, the super duplex steels like Zeron® 100 and LDX2507 are excellent for servicing severe corrosive environments, such as offshore and marine applications. Lean duplex 2101 is available as an economic alternative to 300 series stainless steels.
