Why Mooney Vicometer is so important to the rubber industry

Mooney Vicometer is a rotary viscometer, which is designed according to the principle of fluid mechanics. Mooney Vicometer should meet the requirements of ZBN72024. It consists of a rotor, a cavity, a temperature control system and a torque measurement system.

Mooney Vicometer is often used in the rubber industry because the Mooney viscosity reflects the quality of rubber processing performance, the molecular weight and the wide range of distribution. The compound with high Mooney viscosity is not easy to be mixed uniformly and extruded. Its molecular weight is high and the distribution range is wide. Low Mooney viscosity rubber is easy to stick to the roller, its molecular weight is low, and its distribution range is narrow. If the Mooney viscosity is too low, the tensile strength of the cured product will be low. Mooney viscosity and time curve can also show the performance of rubber vulcanization process.
The manufacturer of Mooney Vicometer tells you that the current production of environmentally friendly reclaimed rubber is mainly based on dynamic desulfurization process. Due to various influencing factors, the Mooney viscosity of environmentally friendly reclaimed rubber products and their storage process is unstable, which affects the processing and product quality in the application of rubber products. Therefore, the stability of the Mooney viscosity of environmentally friendly reclaimed rubber has been improved. It has become a common concern for rubber recycling companies.
The Mooney Vicometer manufacturer tells you that Mooney viscosity mainly affects processing performance. The Mooney viscosity is high, and there are certain difficulties in the mixing and extrusion process, but the viscosity is high, the shearing force is large, and the mechanical properties of the final compound are better.
The Mooney Vicometer manufacturer tells you that the Mooney viscosity value is closely related to plasticity. A high viscosity value indicates that the rubber has a large molecular weight and poor plasticity. On the contrary, the rubber has a small molecular weight and good plasticity. Reasonable control of the rubber Mooney viscosity value is beneficial to the mixing of rubber. Refining, calendering, extrusion, injection and molding vulcanization and other processing technologies, so that the vulcanized rubber can obtain good physical and mechanical properties.
The manufacturer of Mooney Vicometer tells you that environmentally friendly reclaimed rubber is mainly composed of three main raw materials: rubber powder, softener and activator, and the stability of the raw materials is the main key issue. The manufacturer of Mooney Vicometer tells you that the rubber powder comes from all kinds of waste tires and various rubber products. The quality stability of the rubber powder itself is a relatively difficult problem to control. Therefore, stabilizing the raw material source of the rubber powder and quality control are the guarantee for the recycled rubber door. The primary factor for the stability of the viscosity.
The second is the softener problem. At present, the main softeners are mainly pine tar, tall oil and vegetable oil. The Mooney Vicometer manufacturer tells you that these softeners are generally industrial by-product softener raw materials. Due to their different sources, these softeners Quality consistency itself has problems. Therefore, the quality consistency control of softener raw materials is the second important factor to ensure the stability of the Mooney viscosity of recycled rubber.
