Collar Machine Required: offset press machine maintenance of the waterway mainte
Print Network HC Water is responsible for providing ink to the plates required for the water balance. Water, the less the better, this structure after the process of its smaller. But the water is too small, ink-water balance is difficult to control, this is the requirement that it is in good working condition. The following chart through the waterway of the transmission chain of the water chamber maintenance precautions:
Pelton Pelton roll string mass of water roll water roll Roll with water sheets plates Pelton is dressed
Fountain Solution Used as Fountain Solution Acidic, the sink should be acid. Before work in the sink to clean fountain solution, or because the evaporation of water, sink inside more and more concentrated acid solution, the corrosion is also growing. Pelton inside surface of the water should not be too high, or sink, work roll fountain solution may be to throw. Pelton also should pay attention to after working long hours, there may be caused by acid corrosion, should be regularly checked their corrosion. Otherwise, once broken, fountain solution may be spilled drum up, making the city drum surface rust. From the perspective of protecting Pelton, pH, the closer the better 7.
Sink roll is to control the amount of water used to, the surface should be acid, denounced the oil, water absorption; In addition the surface should be clean. If the sink roller surface coating is damaged, it will affect the water supply; it should be promptly replaced if damaged. If the surface of ink or oily or something, the need for timely wipe, otherwise it will affect water supply stability.
Transfer roller is the role of the water to scoop the water roll on roll pass rate of the water. If the force on both sides of their uniform, it will ensure a smooth transfer fountain solution. Glue down the water surface should be uniform, not in some places are down, some places do not. In case this situation should change in time. Glue down the surface of the water should be kept clean and shall promptly remove any dirt, to be washed daily.
String is the role of water roller circumferential and axial directions Beat both fountain solution. Roll on the surface of the water requirements of series with the sink roll.
Roll is the role of the water directly to the plate surface, the supply of fountain solution. Their work directly affects the quality of Indian goods level. Roll their requirements more stringent than the mass of water. The other is the pressure between the printed version should be strictly controlled. Too easy to form the impact is too small may affect the amount of water.
Non-Chinese part of the plate surface should have good water absorption, while the graphic part of the exclusion of water. But Print As the plate when the wear surface may undermine its hydrophilicity, the ink roller and the pressure between the plates, rubber and the pressure between the plates to be strictly controlled. Plate should also pay attention to their own protection.
Blanket Itself should be hydrophobic, but always more or less to the printed version of the paper on some of the water to go. To Blanket Is, the worse the better the surface water absorption, while the more intense the ink better. If this feature is destroyed, you need to replace the blanket.
Sheets is the end of the waterway. From the perspective of sheets of water smaller, the smaller of its expansion. In general, offset paper, expansion coefficient, should reduce the amount of water. Ability to resist expansion of the coated paper, water can be relaxing its control.
