Aluminium Lithographic Coil (also called PS panel) is a professional material that used for the printing application. It has high surface quality requirement. It is produced by surface degreasing solution, drying, photosensitive coating treatment and cutting to the specification that customer required.
This products are popular with national and overseas markets for its good quality and competitive price. such as southeast Asia, North America,Europe and so on. If you are interested in our products, welcome to contact with us
We professionally offering PS plate with below characteristics:
1 Photosensitive Coating
Consisted by imported photographic emulsion and resin, the coating layer of the plate have outstanding alkaline resistance, superior stability, high sensitive and increased adjusting flexibility as well as better resolving power.
2 Vacuum ventilating layer
With tiny ventilating grain layer on the surface, the vacuuming time during exposure can be greatly decreased, as well as preventing the proportion of tiny dots from exposuring to vague.
3. Water Receptive Layer
Excellent water reception capability speeds up the ink-water balance procedure and helps to reduce water absorption during printing process. Superior water retaining capability do effectively prevents non-image areas of the plate from scumming and avoids paper from distortion. Consequently, the printing quality improved
4. Multi Grain Layers
Multi grain layers polish up water receptive property of the non-image areas on the plate. It increases the ink /water adjusting flexibility, make sure the developing performance of the tiny dots. It also strengthens the dots’ adsoption power to the coating layer, which can consequently extend the run-length of the plate.
5. Anodic-Oxidized Layer
A durable and strong oxidized surface formed after the anodic oxidation process on the aluminium material, which can help to prolong the run-length. This layer can also resists the corrosive effect done by the correction fluid.
Ultrasonic Waves. Principles and Science.
Ultrasonic waves and sound waves are fundamentally the same. A hand pistol (gun) is fired. A man plays a mouth harmonic. Another man plays a drum, a hand compresses the drum head. A burning candle is placed on the side of the drum, as the drum head is hit, air blows out the candle flame. The drum head is hit with drum sticks. A tuning fork vibrating. A loud speaker vibrating, as it vibrates it imparts energy to the air in such a way that a candle is blown out. Another loud speaker emitting low and high frequencies. A diagrammatic representation of the normal range of human hearing. “Ultrasonic waves”. An outstretched bat. Bats hanging upside down. Close up of a bat’s ear. Bats flying inside a barn. A dog walks along a country path, a man wearing a raincoat and carrying a shot gun walks behind the dog. The man blows on the ultrasonic whistle, close up of the ultrasonic whistle, the dog running. Drawing of a ship or of a submarine, the ship produces a beam of ultrasounds to the bottom of the sea. An ultrasound generator is loaded from a ship onto the sea, the power is switched on. Close up of a man observing the ultrasound reflection on a machine. Close up of a transverse section of a loud speaker. Close up of the loud speaker. A man stands next to a power unit and holds a wave generator (a magneto-Strictor). Close up of the Magneto-Strictor. A man stands next to a special Magneto-Strictor which is composed of nickel coils wrapped with solenoid winding. Close up of the dial indicator which measures the expansion of the coil when the current is turned on. Close up of the current being turned on. Close up of the dial indicator measuring the expansion of the coil. A magnified close up of the coil to show that it vibrates. Close up of the coil of a crystal transducer, another type of wave generator. Diagram illustrating the ordinary loudspeaker frequency range, the Magneto-Strictor frequency range and of the quartz crystal transducer. A loud speaker spreads sound in all directions. A crystal transducer is placed in a water tank, and a reflector is placed in front of the transducer, a screen is placed outside in front of the tank and the room is darken. A mercury lamp is directed to create a shadow of the transducer and reflector. Close up of the power unit. Close up of the ultrasonic shadows, they appear as vertical lines on the screen . Close up of the shadow of the ultrasonic waves. A concave mirror is placed in the tank in front of the transducer, the ultrasonic waves produce a water fountain. Shadow photography shows how the waves are focused by the concave mirror. Top view of the tank revealing the position of the transducer, mirror and beam. A candle flame is held above a drum head while it is beaten, a trofet? is placed above the drum head and the flame gets blown out. A glass funnel concentrates ultrasonic waves, these concentrated ultrasonic waves carry enough energy to light a cigarette. A man smokes a cigarette lit by the ultrasonic waves. Close up of the man’s mouth inhaling and expelling cigarette smoke. Close up of a funnel shaped Magneto-Strictor drill. Carbon mixed with water is placed on top of a glass plate, the glass plate is drilled by the funnel shaped Magneto-Strictor drill. Close up showing the drilling. An underneath shot shows the shape of the drill as it drills the glass. A microscopic shot of the drilling, tiny pieces of glass are seen been chipped away. The drill comes through the glass. A view of the drill being lifted from the cut glass, and a close up of the cut shape. Close up of a ship’s propeller showing signs of surface pitting (cavitation). Cavitation is described in the laboratory using a Magneto-Strictor: A piece of glass coated with aluminium is placed in the water tank 1/2 inch away from the Magneto-Strictor, as soon as the power is turned on, one can observe the aluminium being eroded from the surface of the glass. A close up of the ultrawaves eroding the aluminium, cavitation bubbles tear at the aluminium. Close up showing a hole being torn on the aluminium surface. A man pours water into a beaker containing oil, the oil will not mix with the water, however when a Magneto-Strictor with a long probe is put into the beaker, the cavitation action mixes the oil and water. Close up of cavitation mixing oil and water.
