Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of polyethylene particle production, in particular to a cross-linked polyethylene finished product particle size analysis device. Background Art
[0002] In the actual production process of cross-linked polyethylene insulation materials, due to different machines, different operating habits of the operators, and other objective and human factors, the particle sizes of the finished cross-linked polyethylene products will vary. When shipped, the finished products produced by different units or the finished cross-linked polyethylene products produced by the same unit with different formulas / different time periods will have different particle sizes. If the finished particles with too large size differences are used in production, there will be risks such as unstable glue output and fluctuations in the insulation layer.
[0003] At present, there are no specific control measures for the size of finished product particles. Generally, technical personnel or production personnel observe with the naked eye. If there is no obvious difference, the product will be shipped normally. However, relying on the experience of technical personnel or production personnel for control is prone to problems. If more sophisticated instruments are used to measure the particle size, it is time-consuming and laborious, and the size of the finished product particles cannot be adjusted in real time. If it is found that the particle size is unqualified, then it is adjusted. At this time, many unqualified products have been generated, causing losses. Therefore, we propose a cross-linked polyethylene finished product particle size analysis device to solve the above-mentioned problems. Utility Model Content
