The world-wide competition in paper manufacturing is becoming fiercer and more complex. To survive in such a complex environment, enterprises must work hard to improve quality, reduce waste, and increase output, so that the production process of the enterprise is more effective. The following is a brief introduction to some new methods and technologies that can improve the paper feedability.
The current situation is that many companies spend a lot of energy on storing and saving fibers, including the use of lighter materials, the use of paper with higher ash content, and the extensive use of recycled fibers. Although this saves material, it affects the paper feedability of the roll paper, which reduces the quality of the paper produced. At the same time, the paper manufacturer must speed up the machine to keep these papers in a normal state during the production process. When producing such paper, there is no gap between the machine and the paper, making the dryer unable to work properly. To handle such high-sensitivity paperboard, better rollers are needed, and paper pressure must be precisely controlled.
In recent years, through the use of consistency profile, an innovative design has been invented, this is the cross-type paper quantitative compression profile. By changing the consistency to control the basis weight of the paper, the blade can maintain consistency in the cross machine. When the knife edge and the baffle plate are parallel, the jet velocity will change, resulting in uncoordinated fiber orientation. Both the profile and the knife edge must pass through the machine's transverse cut, and the weight control does not depend on the control of the fiber angle. One of the main advantages of the consistency press is that the running speed of the paper machine can guarantee the quality of printing. The consistency pressure type makes the machine cold start, gear number change and shut down the machine takes less time than other technologies. The final effect of using this technology is that a lot of cost is saved and the product quality is greatly improved.
The ENP technology is a major technological breakthrough in terms of web feedability. This technology was first used in the production of linear cardboard and corrugated paper. The increased squeezing force of this technique increases the dryness of the paper. For this reason, it has become a technical standard in the cardboard industry. The operating speed of some ENP technologies can reach 1500KN / M. Now ENP technology has been widely used in identifying paper grades. A large number of experiments have shown that under the technical conditions of ENP, the dryness of the cardboard can reach the level of 6 points. Because of these advantages, ENP technology is a powerful auxiliary tool in the process of producing fine paperboard.
Pulp is also a very important factor in ensuring paper feedability. Now, the automatic system has been used to detect the consistency, freeness, average fiber length, fiber length distribution, curl and roughness of the pulp. In addition, it can also detect brightness, color and luminosity.
RRS MICROPOS is the latest equipment to control the pressure of the impression line. This control equipment can monitor the hardness and pressure of the product, which guarantees the quality of the product to the greatest extent. Because it can quickly determine the location and cause of paper breakage, this digital system is now being widely used in paper mills, it can solve the problem of paper breakage to the greatest extent.
Minolta has launched a CM-3630 spectrophotometer, which can detect color, brightness and fluorescence in time. ABB has invented three new form tool machines, one is thinning machine tool, one is weight form tool machine, and the other is blade form tool machine. These new profiling machine tools can quickly detect changes in paper basis weight and coating basis weight, thereby improving product quality.
NDC has released a detection system that can detect dry humidity for paper machines, thereby maximizing product productivity. One of the latest inventions is a new type of monitoring tool that can provide faster and more valuable data and issue early warnings of potential quality problems, thereby keeping the machine in a fast working state. This monitoring tool is mainly used in paper machines, and the use of this tool can maximize the paper feedability.
