Spinneret or metal sintering net cleaning method

Abstract

The invention specifically relates to a spinneret or metal sintering net negative pressure cleaning method characterized by comprising the following steps: 1, heating up a to-be-cleaned spinneret; 2, placing the spinneret of the step 1 into liquid nitrogen for cooling; 3, carrying out ultrasonic cleaning for the spinneret; 4, placing the spinneret into a negative pressure environment so as to separate and precipitate attachments on the spinneret surface and feed hole inner wall surfaces from the spinneret, thus realizing thoroughly cleaning effect. The whole spinneret or metal sintering net cleaning method is very concise in process, can completely and fully clean the surface and each ultra-small hole of the spinneret, and secondary pollution is prevented.

Description

technical field [0001] The invention relates to the field of fiber yarn manufacturing equipment, specifically to a cleaning equipment for spinnerets or metal sintered nets and a negative pressure cleaning method thereof. Background technique [0002] Spinneret is widely used in the field of fiber manufacturing, such as glass fiber, aramid fiber, carbon fiber, PE fiber and other fibers in the manufacturing process, must flow through a plate with many very small holes and then be cooled and formed. This spinneret is also called spinneret. The quality of the spinneret (head) is an important condition to ensure the quality of the finished raw silk and a good spinning process. Its function is to extrude the precisely metered spinning solution through numerous micropores on the spinneret (head) to extrude fiber bundles with a certain thickness and fine texture. [0003] The problem now is that due to the viscosity of the raw materials in the liquid state, after a long time of us...

AI Technical Summary

Problems solved by technology

[0003] The problem now is that due to the viscosity of the raw materials in the liquid state, after a long time of use, the holes on the spinneret (head) and the holes on the metal sintering net used together will be bonded to the remaining raw materials in the holes. while clogging

The diameter of the wires flowing through the spinneret (head) and metal sintered mesh is not uniform, which affects the product quality

Traditional cleaning methods or heating or ultrasonic cleaning, all have the defect that the attachments in the spinneret (head) guide holes cannot be completely removed
