Tungsten Alloy Shielding For Digital Compound Machine

Tungsten alloy shielding for digital compound machine is used to shield the radiation released from the digital compound machine. Digital compound machine, also known as copying machine, is the ultimate tool for the modern office. It is a machine that outputs document in the form of laser printing and can edit and operate images and text as required. In addition to the basic function of copying, it also can be used for printing, scanning, fax, etc. Digital compound machine is to translate the optical signals of original manuscript scanned by the optical system into electrical signals by CCD, then process the image signal through digital image processing circuit and input them into the laser modulator. Modulated laser beam will scan photosensitive drum which is charged to produce electrostatic effect, and complete the copying process after developing, transfer printing and fixing. Digital compound machine substantially has the same functions with laser printer and scanners.

The form of laser printing used by digital compound machine is an electrostatic digital printing process. It produces high-quality text and graphics by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a "drum" to define a differentially-charged image. The drum then selectively collects electrically charged powdered ink, and transfers the image to paper, which is then heated in order to permanently fuse the text or imagery. Today, it is accepted that even low-power lasers with only a few milliwatts of output power can be hazardous to human eyesight when the beam hits the eye directly since the laser has thermal effect, light pressure effect, electromagnetic effect and biostimulation. And laser radiation can also cause skin burns with difficulty heals, skin aging. What's more, the electromagnetic radiation released from digital compound machine also easy to cause fetal malformation, miscarriage, premature birth. Therefore, it is better to put a tungsten alloy shielding around the digital compound machine to shield the radiation generated from it.

Tungsten alloy is a tungsten-base alloy with addition of some other elements. According to the research, the radiation shielding performance of a metal material increases with the enhancing of its density, the density of tungsten alloy can reach very high, and therefore it has great radiation shielding ability to effectively absorb and shield radiation released from the digital compound machine, so as avoiding these radiation damaging office workers. With the popularity of digital compound machine in major offices, tungsten alloy radiation shielding for digital compound machine will also serve as a radiation shielding appearing in major offices.
