Description

Technical Field

[0001] The present invention relates to the field of fiber technology, and in particular to a preparation device and a use method of medium- and high-strength polyethylene fibers. Background Art

[0002] Patent application number CN201110285390.8 discloses a method for preparing high-strength polyethylene continuous fibers and the resulting products. By adopting the above technical scheme, the method for preparing high-strength polyethylene continuous fibers of the present invention shortens the standing time, and the newly-generated jelly fibers are allowed to stand in a vacuum environment above room temperature to promote phase separation of the jelly fibers, allowing a large amount of solvent to precipitate, thereby reducing the amount of extractant used.

[0003] However, there are also some problems with the preparation method of the high-strength polyethylene continuous fiber and the resulting products. For example, the dissolving tank for dissolving the material can only be stirred using a stirring frame, and the contact area between the stirring frame and the material is limited, so it can only drive a small amount of material to move. The stirring of the remaining material needs to rely on the material driven by the stirring frame. This results in the material being stirred less and less active the farther away from the stirring frame, and it is impossible to drive all the materials to rotate at the same time, which affects the stirring effect and requires long-term stirring. Moreover, the concentration of the medium and high-strength polyethylene fiber material is high after dissolution, and the resistance to the rotation of the stirring frame is large, which puts a great burden on the motor and even needs to be equipped with a professional ultra-large torque motor. At the same time, the dissolving tank often needs to work continuously for several hours or even a whole day, and its transmission structure will heat up after a long period of operation, and the structure will easily overheat. The overheated structure is more prone to wear and tear, and the loss of lubricating oil is also aggravated. Summary of the invention
