Description

Technical Field

[0001] This utility model belongs to the field of viscosity detection technology, specifically relating to a viscosity detection device for resin reaction vessels. Background Technology

[0002] Resin generally refers to an organic polymer that softens or melts when heated, tends to flow under external force when softened, and is solid, semi-solid, or sometimes liquid at room temperature. In a broader sense, any polymer compound that can be used as a raw material for processing plastic products is called a resin.

[0003] In resin synthesis reactions, viscosity is a key parameter for judging the reaction progress. Traditional resin production relies on experience to determine the reaction endpoint, requiring multiple viscosity measurements. Traditional viscosity measurement involves inserting a viscosity sensor from the top of the reactor into the vessel to measure the resin viscosity. However, this method has drawbacks: it cannot monitor resin viscosity in real time, multiple measurements extend the production cycle, and it can only measure viscosity at one location. Since the viscosity of resin may vary at different points during synthesis, traditional methods have inherent errors. To address these issues, a viscosity measurement device for resin reactors is proposed. Utility Model Content
