Press roll part of the rotational resistance is basically comes from the roll surface deformation in the process of contact pressure and recovery of energy consumption.Of course, for a specific pressure zone width and area in terms of stress, deformation of the roll surface is very necessary.If there is no roller surface deformation, pressure zone is prone to the negative aspects of a paper crushing and dehydration.When the rubber hardness and elastic modulus are designed in a specific level, the roll of rotational resistance by other performance of rubber material is required to decide.
To save energy has become an d virtue rolls a major topic in the study of r&d project, through a lot of research and testing, we have recently had some encouraging results.D latest polyurethane products - PressPolar virtue can provide customers with a new energy-saving options.Compared with traditional coating products, containing new macromolecule material PressPolar rubber roller rotation resistance can be greatly reduced.PressPolar main application under the line pressure has a larger deformation of rubber roller diameter squeezing (300-350 kn/m line pressure)

Traditional rubber coated products (WelPress II) and PressPolar drive energy simulation.Although at lower speeds PressPolar still can provide significant energy saving effect.
Traditional rubber coated products (WelPress II) and PressPolar drive energy simulation contrast shows up in here.At higher speed, more frequent load) and load pressure is bigger (greater deformation of rubber), the greater the influence of the roll cladding layer.Even at low speeds, PressPolar still can provide significant energy saving effect.
As shown in figure, the difference of 40 kw can provide a year 340 MWH of energy saving effect.Depending on the area of the electricity price, can save about 30000 euros a year.Energy saving is not only feasible in theory, is also in the actual paper machine production process was confirmed.
In addition to energy saving, PressPolar cladding layer can don't need internal cooling water.This means saving water pump drive and water cycle system maintenance costs.No internal cooling water system, the phenomenon of water seepage of sub internal also can be avoided.In addition, in the field of modern paper industry, PressPolar is the wear-resisting, one of the most durable polyurethane coated products.
