Hazardous part 1: The reason for the paper feed wheel: Reaching out or standing on the paper feeder to get the damaged cardboard: The hand or foot is caught in the paper feed roller. Protective measures: Handling dangerous parts according to regulations 2: Printing machine opening and closing Reasons for the incident: When the equipment is closed, there is no notice. The person has not come and left or the hand has not had time to take out the injury: the hand or the body is caught by the equipment. Protective measures: When opening and closing the machine, pay attention to remind the staff of the dangerous part three: printing machine Causes of slotting: When the knife is disassembled, the hand is cut, or when the hand is turned, the hand is touched. The hand is cut. Protective measures: Take extra care when disassembling the knife. Do not touch the dangerous part when the machine rotates. Four: Printing cylinder and anilox roller Cause: When installing the printing plate, do not pay attention to the injury situation: the hand is involved in the printing cylinder and the anilox roller. Protective measures: install the printing layout, first turn off the printing machine, and inform the staff . The combination of tool dismantling and equipment demolition eventually rescued the injured and immediately sent it to the hospital. Because the machine stuck the injured person's right foot, the blind action would cause a serious second injury. After the commander weighed, the decision was taken. The rescue method combined with tool disassembly and equipment demolition, first fix the machine with a safety rope, then use the non-tooth saw to cut and dismantle, and the firefighters use the carton board to isolate the ground to prevent the Mars from splashing. To the injured. The angle of the scraper should be appropriate. The inclination of the metal scraper should be ≤23°-25°, and the inclination of the PE scraper should be slightly larger. Compared with the prior art, the utility model has the following beneficial effects: comprehensively utilizing bamboo raw materials, preparing bamboo raw long fibers to form woven bamboo raw fibers, preparing bamboo raw short fibers to form cellulose whiskers, and using cellulose whiskers to be woven. The bamboo fibrils are modified and finished to obtain bamboo fibrils modified by nano cellulose whiskers. The holes in the cable require a seal. The six common causes of the softening of the carton are: the rainy season, the wet weather, and the humidity. When the paper is processed, the fine fibers are easy to fall off, resulting in hair loss, which is not conducive to the later hydroentangle compounding and use.
Cardboard raw paper and corrugated paper, especially the material of the tile wire, have poor water absorption. The pattern printed with engraved gravure inks exhibits thick and distinct colors, fine and clear patterns, and rich and delicate layers. After the storage environment is off, the cardboard should be taken out of the hot air that has not been dissipated to avoid the condensation caused by the temperature difference. The environment of the storage cardboard or carton should be kept ventilated and ventilated. The cardboard carton cannot be placed directly on the ground, and the pad (pallet, splint) is used. Inherit. So Minera applied the coloring material on the engraving plate, wiped off the color of the non-recessed part of the plate, and then applied the paper with heavy pressure to transfer the color material in the groove to the paper, which was beautiful and unique. The prints have a special bumpy feel and the anti-counterfeiting effect is obvious, which greatly inspires the printing of banknotes. Customers with branding needs and advertising needs use another way to order POS paper. The cleaning degree of the cylinder surface of the large drying cylinder and the tightness of the scraper: the long-fiber low-slurry degree is relatively insufficiently combined with the paper fiber. If the large-cylinder scraper is not tight, the paper scraps are easily brought into the paper, causing hair loss. When the press part blanket is improperly selected or the use period is too long, the local dehydration ability is insufficient in the later stage, and when the elasticity is poor, the surface modification of the paper should not be replaced regularly. The second stage uses a floating separation method to separate solids with large buoyancy. The precipitation method is to separate the fibers and the filler by means of sedimentation, so as to recover the fibers and fillers and clarify the white water. After arriving at the scene, the fire commander quickly learned about the scene and found that a worker in the workshop of the printing plant was accidentally stuck in the right foot and could not move the machine while operating the printing press. Therefore, under the conditions of satisfying the vertical and horizontal wet and dry strength of the paper and the normal production of the paper machine, the degree of beating is reduced as much as possible. In addition, consideration should be given to installing a filter unit to prevent problems in the white water recovery system and causing fluctuations in water quality. To this end, we have developed and developed a reverse oblique blow type high efficiency hot air nozzle as shown in Fig. 3 (right). Solution: It is recommended to use van trucks, which is also the trucks commonly used by major suppliers. The ink is in a three-dimensional state on the paper, so that touching it by hand may have a feeling of unevenness. In the mid-eighteenth century, the Austrian bank tried to make banknotes with a harder and more wear-resistant steel gravure. Production process technical conditions 1 slurry ratio using 100% bleached sulfate softwood pulp (indicator: brightness 88%-90%, dust degree not more than 25mm2 / kg, fiber length not less than 0mm, pulp degree 13-15OSR) . When you receive a RMB, if you do not have a money detector at hand, what to do if you determine the authenticity. In addition, white water closure can have varying degrees of impact on paper performance.
1 Check the task manager to check the memory to see if there is a memory leak. If it is not treated in time, the blood vessel necrosis will be at risk of amputation.
