The aging phenomenon of rubber rollers is an inevitable occurrence in the life of the product!

The aging phenomenon of rubber rollers is an inevitable situation in the life of products. As a professional roller technology production and processing unit, Laiwu Likai Machinery Co., Ltd. today specially introduces the aging phenomenon of rubber rollers in what aspects.

1. When the stretched rubber roller produces ozone aging, the surface will produce ozone cracking. The ozone cracking of the rubber roller has a critical stress. When the elongation or stress of the rubber is lower than the critical value, it will not produce cracking when ozone aging occurs.

2. The ozone aging of rubber rollers is a surface reaction, and the reaction depth of the unstressed rubber surface is 10-40 molecules thick.

3. When the rubber roller produces ozone cracking, the direction of the crack is perpendicular to the direction of the force. This is the difference between ozone cracking and photo-oxygen aging cracking.

Continuous product iteration of the winding core shaft reinforces the foundation for precision coil production.

In coil-processing lines for metallurgy, galvanizing, cold rolling, thin films, papermaking, and other applications, the take-up reel core shaft is a critical functional component of both winding and unwinding equipment, primarily responsible for load-bearing, torque transmission, and stable tension control. The operational accuracy, structural stability, and durability of the core shaft directly determine the coil’s shape, flatness, and surface quality, making it an essential part for ensuring the continuous and reliable operation of the entire production line. As downstream demand evolves toward high‑end sheet materials and precision flexible substrates, take-up reel core shafts are undergoing ongoing structural and process optimization to align with industry trends toward higher speeds, greater precision, and increased intelligence.

Steel Strip Galvanizing Line Reel: Iterative Adaptation of Core Line Components to Support the Upgrading of Steel Manufacturing

In the continuous hot‑dip galvanizing process for steel strip, the reel—serving as the core component of the uncoiling and recoiling units—plays a critical role in supporting the strip, transmitting tension, and forming the coil. The operational condition of this equipment directly affects the surface quality of the galvanized strip, the coiling geometry accuracy, and the overall efficiency of the production line. As domestic galvanized sheet‑metal capacity undergoes upgrading, improvements to reel‑manufacturing processes have also attracted considerable industry attention.
