Paper Mill Machinery Rubber Press Roller
Paper mills have been using rubber press rolls in different stages of the paper making processes for many years.The success of rubber roll covers depends on optimal physical and mechanical properties of the cover composition.
For example, a cover with improved abrasion resistance increases the operating time between regrinds.Dynamic modulus and hysteresis properties are critical when determining if a cover material will run successfully in a given set of nip conditions.Several new covers have been introduced for press, size press, Yankee pressure, and coater backing applications.These new covers are listed in Table 1.Additionally, most of these rolls can now run non-water cooled, which provides a measurable benefit to the paper maker through energy savings.it's benefits when used with rubber covers will also be illustrated.
1. Low hysteresis to run cool-Hysteresis is power loss in the form of heat during deformation and recovery of the cover through the nip cycle.
2. High tear strength -Superior toughness to withstand impact at high loads without cracking.
3. Superior abrasion resistance - Maintains crown and venting profile. This will also increase the time between regrinds.
4. Superior bonding system -The cover must stay well bonded to the shell and intermediate layers.
