For areas that are difficult to maintain, such as fueling, cleaning, decontamination, etc., effective measures should also be taken to improve the maintainability of the equipment. A set of text or color blocks is overprinted by multiple units, increasing the difficulty of printing. The departure of employees after the year is a common practice for many printing companies, especially the loss rate of front-line staff is more serious. The use of flexo printing to produce corrugated boxes requires the pursuit of exquisite patterns on the one hand and the difficulty of printing on the other. For English words, especially small ones, it is necessary to consciously bold the strokes to avoid thinning or even dying of the strokes due to ink spreading during printing. The slag remover concentration and the recoil effect are poor. The rinsing tank often provides the concentrated water and backflushing of the slag remover. For example, if the booster pump is equipped, the liquid level fluctuation will affect the slag removal. The concentration of the device (when the slag separation effect is deteriorated at ≥1%) and the recoil effect (the backlash is caused by the tail slag blocking or the fiber recovery efficiency is lowered). Maintenance management equipment has failed and maintenance has not been prevented first. Therefore, it is necessary to strictly comply with established standards, such as "cleaning", "refueling standards" and "self-inspection standards". Here, a method for preparing nanocellulose by low-intensity ultrasonic assisted amino acid ionic liquid is provided. How long is the shelf life of thermal paper? For NCC, the higher the crystallinity, the better the thermal stability. The color density of the composite film and the upper matte oil print is reduced. Externally, the workshop director should communicate well with the relevant department workshops. The flat net board is made by 1:1. If the flat screen laser plate making is adopted, the net point can withstand a certain pressure, and the expansion rate will be greatly reduced, which can greatly reduce the probability of occurrence of the rib stripe phenomenon. The second phenomenon (there are color differences among the same batch of colors, some are consistent with the sample, but some are inconsistent with the sample). Human factors: I think that the first few colors are accurate, and when the ink is not balanced, it starts all the way. In the printing process, the water and ink volume are constantly adjusted, and the side is opened and closed, which will inevitably cause color difference in the color of the same batch of printed products. This has a great relationship with the skill level, experience and personality of the captain. The color difference of the same batch of products caused by insufficient. Offset color printing is when the light is incident on the surface of the paper, the light is reflected to the retina of the human eye, and the color is seen by the photosynthesis received by the chromophoric cells. Generally, we require coloring under natural light conditions (ie, standard light sources). In the low-intensity ultrasonic assisted process, the cavitation of the ultrasonic wave will form mechanical vibration energy and vibration waves, which is more conducive to the promotion of fibrillation inside the fiber. Under this condition, the hydrogen bonds between the fiber chains in the corn stover are destroyed. The biomass fibers are gradually decomposed into nanofibrillated fibers. In the process of learning and execution, we must continue to learn and be familiar with the operation and action of equipment, the correlation between quality and equipment, and the ability to operate the equipment correctly and detect abnormal conditions early. Prepare the cleaning and refueling benchmarks Based on the experience gained in the second step of the activity, prepare a temporary benchmark to maintain the basic conditions of equipment, such as cleaning, refueling, and fastening. When the air content of the water system rises, the level of the slurry tank will fluctuate up and down, which will cause the flushing tank to have no overflow and sometimes a large overflow. This unstable overflow fluctuation is particularly easy to carry a large amount of air into the slurry water system and improve The air content of the slurry brings a series of chain reactions such as running failure, retention efficiency and dehydration efficiency, paper bubbles or perforations, reduced speed of production, reduced production efficiency, increased defoaming agent dosage (even affecting the sizing effect, increasing chemical cost). . Cause white water and clean water waste When the liquid level of the slurry tank drops, it is necessary to increase the amount of supplementary water (usually clear water). When the liquid level of the slurry tank is too high, the excess overflow of white water passes through the net white pool, multiple discs, and clear filtrate. Pool, clean water tower, and finally overflow into the trench. The scraper is thicker due to the scraper, which causes rib peeling and printing paste. There is also no proper cleaning of the equipment, etc., that is, if the work is not done, it will cause the equipment to deteriorate. Why do you want to pass the FSC forest certification?
The product leaves no trace after peeling off the sticker. The conventional printing plate making dots of the printing plate are all bumps, and the display of the dots is mainly controlled by the printing pressure.
