Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of melt flow rate meters, specifically a melt flow rate meter with a protective cover. Background Technology
[0002] A melt flow rate meter is a specialized instrument used to measure the melt flow properties of thermoplastics under certain conditions. Its core function is to evaluate the processing performance and molecular weight of materials by quantifying the melt flow rate.
[0003] A melt flow rate meter, also known as a melt flow index meter, measures the mass or volume of thermoplastic melt passing through a standard die within a specified time under specified temperature and load, thus characterizing the material's flowability. Polymer raw materials (such as granular plastics) are added to a barrel, heated to a molten state at a specific temperature, and a constant load (weights) is applied, causing the melt to be extruded through a standard die at the bottom. The extruded material is then slit, and the slit material is prone to splashing. Traditional melt flow rate meters lack protective features, leading to easy splashing of extruded material and difficulties in collection. Utility Model Content
