Definitions
- the write-only-once-support is manufactured in a manner similar to conventional playback discs. As well as normal CDS, they employ a polycarbonate substrate, a reflective layer, and a top protective layer. However, sandwich between the substrate and the reflective layer, there are a recording layer composed of an organic dye. Unlike normal CDS, a spiral is used to guide the recording laser along the spiral track; this greatly simplifies the design of the hardware of the recorder and ensures the compatibility of the discs. "
- CD-Rs are basically made like this, from top to bottom:
- Reflective layer 24 Carat gold or silver alloy
- R does not have a hard top layer like the Kodak "infoguard", it is very easy to scratch the top and leave a CD unusable.
- a printed CD has higher and lower areas, called “plains” and “holes”, respectively.
- a laser in the recorder creates marks in the organic substrate layer that has the same reflective properties.
- the pattern of holes and plains on the disc encrypts the information and allows it to be recovered in an audio or computer CD player.
- the discs are written from inside the disc to the outside. On a CD-R you can verify this by looking at the disc after writing it.
- the spiral track of a 74-minute disc is 22188 laps around the CD, with approximately 600 laps per millimeter that travels out from the lead-in (23mm from the center) to the outer edge of 58mm .. If we "unwind" the spiral, it would be about 5700 meters (3.5 miles) in length.
- CD-RW The construction of a CD-RW is different:
- Reflective layer (aluminum)
- Taxable layer film that changes state, for example the part that changes shape
- optical media from 1982 to 2001 totals more than 110,000 million units.
- the sector anticipates an annual growth of approximately 15 percent with a consumption of poly carbonate of about 800,000 tons in 2005.
- the trend in this sector is the diversification of formats: a smaller growth is expected for CD of audio and CD-ROM, which until now dominated the market with percentages of 80 percent, in favor 120 rewritable CDs and DVDs and DVDs, whose demand will increase substantially.
- the audio CD and CD-ROM formats are expected to keep a third of the market in 2005, while the other two thirds will be for rewritable CDs and DVDs and DVDs.
- the recycled polycarbonate acquires new characteristics by establishing new chains for the mixture of expanded polystyrene and high density polypropylene, with the original polycarbonate and others under study, in the form of glass or dyes.
- the machinery system is designed to operate either automatically, semi-automatically or manually, which is distinguished by having readings of input signals, and outputs, of detectors that monitor the signals for process control, inputs are handled of accountants
- the design of the machinery is modular and each team can work independently.
- the material used is cold Rolled and high molecular weight polyethylene because it is not in contact with oxidizing diluents and does not handle high temperatures.
- the present patent application relates to a machinery for the recovery of poly carbonate from CD.
- the first process is based on the study of the particle to establish the ideal size for its continuous process.
- the blades were adapted to give greater friction and the ideal size of the particle, it is analyzed under the cutting process and the study of the tension and friction of each particle
- This mill is manufactured in structural steel and 3/16 inch sheet, composed of a rotating shaft or mass, on which three are mounted blades and in the flat part of these on both sides two spatulas were adapted to collect and friction the particles as 185 we observe in Fig. 1, the previous blades rotate clockwise, shearing and collecting the material against the two fixed blades mounted on the structure.
- a screen calibrated with a 6mm hole to homogenize the particles. It has a nozzle system to circulate support air in a circular direction, so that, taking advantage of the
- the hopper (politol) is adapted with horizontal movements which facilitates the diffusion of the enzymatic substance, the hopper has a temperature of 6 degrees
- Each line of force is positively oriented in it. sense of field
- the geometry of the hopper allows the CD particles to slide and facilitates their transport for the third process
- the hopper has an agitation system by means of air with a laminar path, to volatilize the dust molecules that are
- 210 separate, in the lower part has a filter system which separates impurities by means of tubes as seen in fig3.
- 235 has a system of cilia which leads them to a distal tubule which transports them to an annex tank for recovery, its geometric shape is spherical made of 3/16 caliber sheet with flat support in the upper part, to fix the Transport system. It has a solid 2-inch diameter pipe, it is designed to pressurize without any risk, in Ia
- 240 side is a pressure gauge of 0-150 psi for pressure control of 10 and 30psi.
- connection for support air is% NPT, in the upper part it has a pneumatic system that controls a cylinder by means of a directional valve to allow the entry of the material and the sealing of the East tank
- the enzymatic substance impregnated in the CD particles require energy to displace the paper particles and some small residues of the metallic layers that are still in the polycarbonate particle and that is completely decontaminated, as the enzymatic substance has gone through
- the substrate is poor in energy becoming a poor substrate to perform its cleaning reaction
- the electric field system raises the energy level of the substrate to that of the final particle.
- the tower represents the range of potentials for various pairs of redox with the most negative above and the most positive below.
- the dipoles tend to be arranged parallel to the field, although the internal friction of the substance towards the particle is not complete, this combined action allows all the dipoles to have the tendency to orient themselves in parallel, which facilitates that all dipoles are aligned, when applying the dipole the
- the material after the first and second process is apparently separated from the metallic thin layer and the layer of the printed layer but the electromagnetic field helps to detect them and prepare it for the fourth process so that the polycarbonate particle leaves completely separated from the others.
- This equipment is rotary which takes the particle and subjects it to a potential, releasing a discharge on the surface of the polycarbonate by sending them through a pair of electrically charged plates. A helical movement is subsequently printed through an electromagnetic field. This movement
- the particle is then subjected to a vacuum chamber
- bladders which have small fibers in the form of cilia, these are intended for locomotion and filtration of small metal and paper molecules that are still in the polycarbonate particle, and these help propel the air or liquid to a certain direction , the bladders print movement, in this tank we find a temperature between 30 and 60
- the tunnel is made of 1/8 sheet supported on 14 x square tubes
