How to use ceramic reticulate roll correctly? What is daily maintenance? Remember these details!

Ceramic roller is widely used, its surface is a regular porous structure, through direct or indirect (all kinds of resin, rubber plate) way can accurately transfer all kinds of functional coatings,# ink, ink and other types of materials, such as# paper,# plastic, #film, metal, etc. In order to realize the purpose of material surface physical and chemical properties change and rich color, it is often called metering roller, which plays a very important role in the application of flexible printing ink supply system. In the daily work, if the use of the roller is unreasonable, it will not only affect the uniform transmission of ink, so as to harm the printing quality of printed matter, but also greatly reduce the service life of the roller. In fact, there are mostly problems with the roller, and the author starts from the structure of the roller and the principle of ink transmission, and talks about the correct operation of the roller and matters needing attention together. 01 roller structure The structure of the roller is similar to "sandwich", which is composed of roller core, base material and surface coating. Among them, the #roller core is usually metal material, providing support and strength; Basic materials are mostly copper electroplating, used for carving mesh holes and mesh walls; Surface #coatings are common with chromium metal or ceramics, which enhance wear resistance and corrosion resistance. The surface of the roller is evenly distributed with many small concave holes in the same shape, which is commonly called "ink holes". It is these ink holes that play the role of ink storage, uniform ink and quantity ink transfer in printing. 02 roller storage The storage cases of ceramic roller shall be stored in dry places indoors to prevent damage caused by moisture, rain and direct sun exposure. When changing ceramic reticulated roll, the roll surface of ceramic reticulated roll should be protected to prevent collision damage. After the completion of the work, the ceramic reticulated roll must be timely and thoroughly cleaned, do not store the unclean and undry ceramic reticulated roller, when stored with natural fiber packaging foil paper wrapped roll, and then put into the storage box. The ceramic mesh roll not stored in the box should be fixed on the special storage bracket. It is strictly prohibited to tilt the roll surface on the ground, otherwise it is easy to cause ceramic coating damage on the surface of ceramic reticulated roller. 3. Use of roller 1. Angle of roller scraper The Angle between the scraper and the line of the roller contact is generally between 25 ~ 30. If the Angle is too large, its scraper is almost worn over the roller, and the surface of the roller is not smooth. When it is running at high speed, it will cause the vibration or beat of the elastic scraper blade, so that the solution is bounced up, resulting in uneven coating amount, resulting in a large problem of coating volume difference. In addition, too large angles can easily damage the blade of the scraper. 2. new roll run-in Do not make samples of important orders with new rollers unless you have to. Although a network roller is treated by removal of hair, polishing and other processes, and pre-run-down, it can effectively reduce the wear of scraper when used, but this does not mean that the importance of runing in the use of the new roller can be ignored. When the new roll is on the machine, it should pay attention to observe at the same time, when it finds the wire, it should stop and wipe the scraper in time. In general, the hardness of the particles is not enough to lead to the wear of the roller, but it does not rule out that some hard small particles will impact the wall of the wall under the action of the scraper to produce small ceramic clings at the edge of the scraper. In general, it usually takes two to three weeks of continuous run-in. 3. when the shutdown is discontinued for a short time, the roller needs to keep rotating. When long time stops, the roller needs to separate the scraper in time, loosen the rubber pressure roll, clean the floating ink, so as not to use again, the situation that the horizontal uneven ink supply or the component ink is difficult to clean after drying. 4. detection of ink load of the roller for ream Although the high hardness and long service life of ceramic

Printing knowledge - screen printing ink preparation and recycling method

  Printing knowledge - screen printing ink preparation and recycling method In the process of screen printing, the first problem encountered before printing is the deployment of ink color, whether color real reproduction directly affects the product quality and market space share. To make customers satisfied, you first need to know how to improve the quality of ink by using ink color blending techniques. 1 screen printing ink to find a container to put ink to avoid waste (it is recommended to use a transparent disposable cup, easy to be easily poured into the right amount of ink (how much to pour) The ink preparation method is clear basic requirements: first determine the printing material (paper, plastic, metal, etc.), select the corresponding system of ink (such as screen printing plastic ink for plastic, high temperature curing ink for metal). With the basic color as the main body, a small amount of auxiliary color is added, and the amount of each amount is not more than 5% of t...

Printing knowledge - field printing shows maximum saturation

  Printing knowledge - field printing shows maximum saturation   Four-color printing is printed with CMYK(cyan, magenta, yellow, black) four-color overprint that you need. In the popular point, that is, you can use these four different colors to add up to get the color you need. Field printing refers to 100% color, such as 100% black is field black, and printing a large area of color block on printed matter. 1 There are a lot of people in the field saturation in the printing product color saturation do not know how to deal with, it is easy to cause unnecessary loss, theoretically, is to give full play to the maximum field density of #offset #printing #ink to achieve the maximum saturation. Although 95% of the dot will increase to 100% after printing, this is different from the effect generated by 100% field printing. 95% of the dot only reaches the field in 95% dot area, while 5% of the dot area has ink, but the ink #density is thinner. 95% of the dot increases to 100% in...

Analysis of the Causes of Pressure Faults in Inkjet Printers

Image
  Analysis of the Causes of Pressure Faults in# Inkjet Printers 1 The ink line speed is normal, but there is pressure loss or it is too high (1) Check if there are any additives in the additive bucket and replenish them. Check the viscosity of the #ink to determine if it has become thinner (check if the printed characters are too light). Otherwise, the entire machine should be cleaned. For machines that have not undergone regular maintenance, the #filter elements and filter screens must be replaced. (2) Check if the shape of the breakpoint is correct and adjust the breakpoint. (3) Check whether the electrode of the nozzle is clean and clean the #nozzle. 2 Pressure loss fault caused by #pump motor failure (1) Pump motor failure leads to power loss, resulting in total pressure loss and pressure fault display. (2) The motor is disconnected from the pump. At this time, although the motor is rotating, the gear at the front end of the pump does not rotate, resulting in total pressure los...
