Factors Affecting Final Mooney Viscosity Stability - Raw Materials
Environmentally friendly recycled rubber is mainly composed of three main raw materials: rubber powder, softener and activator. The stability of raw materials is the main key issue. Stabilizing the raw material source of rubber powder and conducting quality control are the primary factors to ensure the stability of Final Mooney Viscosity.
The second is the problem of softeners. At present, the main softeners are pine tar, tall oil and vegetable oil. Due to their different sources, the quality itself has problems. The quality consistency control of softener raw materials is the first to ensure the stability of Final Mooney Viscosity. The two main indicators of softener quality control that deserve special attention are moisture and volatile matter, which should be used as key control indicators in production.
The third is the problem of raw material activator. The activator is mainly produced with the by-product of antioxidant production as raw material, and its own quality and raw material stability has problems. In addition to the process control of the production process, the quality of each batch of activator produced exists. Therefore, the quality consistency of the activator is a problem that must be strictly controlled by environmentally friendly recycled rubber manufacturers when purchasing goods. In this way, on the basis of the stable quality of the activator, the environmentally friendly recycled rubber with stable Mooney viscosity can be produced.
