Rubber Mixing Process
\n
In the rubber mixing process, the open mill utilizes two counter-rotating rollers to extrude and shear rubber compounds. This action breaks molecular chains, ensuring uniform blending of all formula ingredients to achieve optimal mixing results. The film discharged from the roller gap wraps around one roller due to differences in surface speed and temperature between the two rollers, then returns through the rollers repeatedly to complete the mixing cycle.
\n
During plasticizing, rubber molecular chains are shortened while elasticity is reduced. During mixing, each component surface is continuously renewed and uniformly blended. On intermittently operated open mills, rubber material passes through the rollers multiple times after feeding before final sheet cutting.
