Solution

1, Problem & PhenomenonMooney viscosity test results were qualified, but obvious differences in roll sticking occurred between batches. For the same cord fabric compound using different batches of natural rubber, roll sticking behavior varied significantly, resulting in mass rejection of semi-finished products, rework, repair, or even scrap. 2, Cause of Roll StickingHigher roll speed increases […]

1, Two batches of rubber compounds (Sample A and Sample B) with identical formulations were tested for curing characteristics using a rotorless rheometer. Results were extremely similar, and both batches would normally be qualified, indicating consistent quality of cured products. 2, Notably, Sample A had a slightly longer TC90 value than Sample B, suggesting better

Rheology: an interdisciplinary and comprehensive subject integrating mechanics, chemistry and engineering. It establishes the constitutive relations of materials such as non-Newtonian fluids, viscoelastic solids, and substances between fluids and solids through experimental or theoretical approaches. In other words, it develops mathematical models reflecting the macroscopic properties of materials, and studies the laws of material flow
