What are the hazards of nitrile rubber roller?
Anti entangling instability. According to the analysis of the work function, fiber friction effect and electrostatic charge diffusion theory of "Holm effect": when the cots and aprons by extrusion, tensile and friction in the drawing operation, will produce electrostatic effect and potential difference. If the potential difference is not zero, it is inevitable to produce fiber winding rubber roller phenomenon. Any two kinds of solid materials, such as rubber and fiber, the chemical composition of different physical states or different, when they contact each other, redistribution of charge will be generated, and produce electrostatic effect and potential difference in the process of separation. In the process of rubber hose production, NBR has been added a large number of additives, which is difficult.
Elasticity and good abrasion resistance can not have both, "care for this and lose that" phenomenon. Elasticity is guaranteed at the expense of loss of wear.
In recent years, with the application of new techniques and techniques, such as core yarn, compact spinning, siro spinning and poly fiber spinning, the fretting requirements of the top roller have been put forward. And the use of NBR cots 7 days - 12 days, there will be wear, groove, concave phenomenon, resulting in fluctuations in quality of spinning. At the same time, the spinning process is developing toward the direction of heavy weight, big drafting, high speed and heavy pressure, and higher requirements for the performance of roller. It is more and more difficult to meet the requirement of spinning, so it is urgent to develop new elastic material and draft rubber roller.
