Embodiment 1

[0024] The processing method of the plugging hole of the spinneret template of the present embodiment may further comprise the steps:

[0025] A. Use a copper plate to scrape off and clean the large slurry remaining on the surface of the disassembled spinneret assembly, and use the spinneret outlet surface as the supporting surface to decompose and take out the connecting plate, distribution plate, knife plate and nozzle Silk board;

[0026] B. Put the decomposed spinneret and distribution plate into the calciner, place the spinneret with the wire outlet facing up, and start the calciner to perform the following four-stage calcination:

[0027] The first stage: set the temperature to 290°C, set the processing time to 45 minutes, and keep warm for 60 minutes;

[0028] The second stage: set the temperature to 450°C, set the processing time to 45 minutes, and keep warm for 120 minutes;

[0029] The third stage: vacuuming for 150 minutes;

[0030] The fourth stage: After the va...

Embodiment 2

[0037] In the processing method of the plugging hole of the spinneret template of the present embodiment, step C uses 28kg / cm 2 The water pressure cleaning of spinneret and knife plate; the water temperature of the first ultrasonic cleaning in step D is controlled at 65 ° C, and the water temperature of the first ultrasonic cleaning is controlled at 60 ° C; the water temperature of the ultrasonic cleaning in steps E and F is controlled At 60°C, the remaining characteristics are the same as in Example 1.

Embodiment 3

[0039] In the processing method of the plugging hole of the spinneret template of the present embodiment, step C uses 25kg / cm 2 The water pressure cleaning of spinneret and knife plate; the water temperature of the first ultrasonic cleaning in step D is controlled at 50 ℃, and the water temperature of ultrasonic cleaning for the first time is controlled at 50 ℃; the water temperature of ultrasonic cleaning in steps E and F is controlled At 50°C, the remaining characteristics are the same as in Example 1.

[0040] The spinnerets treated in Examples 1 to 3 were detected by a spinneret micropore detector, and the inner walls of the micropores were smooth and free of debris.

Abstract

The invention discloses a treatment method for hole blockage of a spinneret template, and relates to the technical field of spinneret template cleaning.The treatment method comprises the following steps: cleaning the surface of a spinneret plate assembly, decomposing and taking out a connecting plate, a distribution plate, a knife plate and a spinneret plate; putting the decomposed spinneret plateand the decomposed distribution plate into a calcining furnace, and performing calcining treatment in four stages: after calcining is completed, firstly cleaning the connecting plate and the distribution plate by using a high-pressure multi-jet water gun, then cleaning the spinneret plate and the knife plate, and then polishing inclined planes on two sides of the spinneret plate and an air passage and a yarn outlet surface of the knife plate; putting the spinneret plate into an ultrasonic cleaning machine, injecting water, adding a cleaning agent, and carrying out ultrasonic cleaning twice; then, carrying out ultrasonic cleaning on the distribution plate and the connecting plate, and then independently carrying out ultrasonic cleaning on the knife plate; and checking all spinneret orifices of the spinneret plate to ensure that all the spinneret orifices meet use requirements. The problems that the labor intensity is high, the working efficiency is low and the spinneret orifices are easy to damage in the existing spinneret template hole blockage treatment are solved.

Description

technical field [0001] The invention relates to the technical field of cleaning a spinneret template, in particular to a method for treating blocked holes of a spinneret template. Background technique [0002] The spinneret template is a key part of the meltblown equipment. There are hundreds or even thousands of micropores on the template. The diameter of the micropores is usually below 0.2mm. The viscous polymer melt enters the die of the spinneret box After the flow channel, under the action of hot air flow, it is sprayed out through the micropores on the template, and rapidly condenses and solidifies to form fiber embryos. Impurities are unavoidable in the melt-blown raw materials. Due to the small diameter of the micropores of the spinneret template, in order to reduce the probability of plugging of the spinneret template, a melt filter is usually installed at the extrusion head of the plastic extruder, but , some small impurity particles will still enter the micropore...
