What is the paper Cots paper rolls for papermaking rubber rollers. A Fourdrinier popular eighty seven have size rollers. According to the structure can be divided into rolls (flat roll surface no pattern), grooved roll (surface coating layer with a groove), thread rolls (surface layer coated thread groove), the vacuum roll, Curved rolls ( Hollow bending) and high-roll. Distinguish substandard parts for squeezing water from the paper machine, press, calender and other results. Popular manufacturing various types of SR (such as PU, etc.). Ministries for paper machine in a large, thick-walled rollers. According to the press can be divided into sub-function rubber roller and press rubber roller driven by the types of slave rollers. Cots press should be able to withstand high pressures, and to drive the results from the other dependent cot, high hardness, in Shore 85 ° ~ 95 °. When the upper and lower pulp by squeezing through two rollers, the roller (cast iron roll core, outsourcing, brass or hard rubber) by the pressure oblige moisture out, and the next roll (ie press Cot) from supporting the outcome. Cots driven by the press some dependent cot collecting breast roll (the first paper machine rollers, roller supporting copper mesh case (also known as dewatering roll, supporting the copper network), scraper roller, brush roll. Its plastic layer should have good elasticity, shrinkage resistance, flex resistance and thermal conductivity. The maximum hardness tolerance should be allowed within limitations, otherwise it will constitute a pulp pressed dry and affect the degree of uneven paper quality. Popular in Shore hardness 40 ° ~ 100 °, tolerances ± 2 ° ~ ± 4 °. hardness depends on the printing rollers rubber material to staff members, a good quality of printing rollers, printing have good hardness, in the printing process First it is dependent on rubber material, followed by post-processing principles printing rollers hardness is certain: in Sheung Shui and to ensure good ink capacity, and there is sufficient under the premise of resistance to chemical corrosion and physical effects capabilities, Hardness printing rollers should be appropriately reduced. In the actual printing application, choose the appropriate type of plastic rubber material and can be avoided due to the rubber roller printing quality caused by failure to ensure that the printing is relatively stable and smooth. In addition, different places Cots, having different properties of rubber-based adhesive roller presses used in automatic cleaning apparatus for cleaning a good transmission and self-cleaning ability, and good corrosion resistance; In addition, now have to specifically address In addition to hair and dirty cot paper paper dust problem. The importance of a good debugging printing rollers long been engaged in the printing industry who are well aware of the importance of printing rollers, because it is a direct relationship with the plate, and product quality has a thousand Wanlv silk ties, whether you are using offset printing, letterpress printing, gravure, flexo presses are faced with how to choose and debugging skills. If you can not follow its rational use and operation rules, not only India ideal and excellent product, but also damage the rubber roller, but also shorten the life of the printing plate. The printing rollers adjust to the optimum level and ideal point there are some difficulties, not overnight can grasp, because it has no fixed formula , won by leading machine in the long-term production practice summary, exploration, mining, innovation, finishing a set of effective printing skills, so that good printing rubber roller essential debugging.
